Problem using tag

2009-11-20T21:48:24Z

Hi Friends,

I am using the url tag as follows:

<s:url id=*"url"* action=*"InvoiceFrame"*>

<s:param name=*"invoiceType"*>LocalInvoice</s:param>

</s:url>

<s:a href=*"%{url}"*>Local Invoice</s:a>

The problem is the parameter defined in param tag is getting appended in all
others urls on the JSP page so affecting other url's implementation.

Please help me / guide me in resolving this issue.

Thanks,

Shekher.

RE: Confused about Drop down lists (database generated)

2009-11-20T21:31:28Z

You can use org.apache.struts2.util.ListEntry , a default object to hold key
value in Roles list box for JSP page dropdowns.

<s:select label="Role:" name="roleId" list="roles" />

Subject: Confused about Drop down lists (database generated)

All the drop down lists in my application need to be generated from the
database. Some of these lists will be needed for more than one JSP.
So, in order to work with the <s:select> tag I am building an action for
each list.

I know this has to be wrong. Especially because some JSP's will need
multiple drop down lists. What is the best way of doing this in struts
2.1.8? Here is an example create method that I am using and the JSP
that feeds it. Should I be using a better way to get to create from a
JSP? I want to be able to use the roles drop down in multiple JSP's.

public String createUser()
{
User user = new User();
user.setUserName(userName);
user.setPassword(password);
user.setFirstName(firstName);
user.setLastName(lastName);
user.setPhone(phone);
user.setEmail(email);
service.createUser(user);
String userId = service.getUserId(user.getUserName());
roleUser = new RoleUser();
roleUser.setRoleId(roleId);
roleUser.setUserId(userId);
service.createRoleUser(roleUser);
roleUser = null;
user = null;
return SUCCESS;
}

Struts2 Tags Example

2009-11-20T17:18:33Z

I am having trouble iterating/manipulating a collection via struts2 tags.

The layout of my entity object is this:

public class Role
{
private String name;
private String description;
private Long id;
private List<RoleFunctionAccess> roleFunctionAccess;
// getter/setters and annotations
}

public class Function
{
private String name;
private String description;
private String url;
private Long id;
// getter/setters and annotations
}

public class RoleFunctionAccess
{
private Long roleId;
private Long functionId;
private Long accessFlags; // bitmask 1-View,2-Add,4-Modify,8-Delete
// getter/setters and annotations
}

The above simply shows the relationship of the entity beans. In the
rendered JSP page am aiming for something like this:

Role: ADMIN
Description: Administrator

Functions:
Admin Users [ ] View [ ] Add [ ] Modify [ ] Delete
Admin Customers [ ] View [ ] Add [ ] Modify [ ] Delete

My action renders the content from a display perspective ok, but it's
getting the checkboxes related to the functions configured properly so
that when the form is submitted that the appropriate
RoleFunctionAccess beans are updated with the correctly bitmasked
accessFlags values.

Can anyone help point me in the right direction?

Why don't you show your complete action configuration with all the result
entries (better include and global results as well).
Do you define a result of name="input" as required for validation failure?
What version of Struts are you using?

s2: Possible bug found - how to report it?

2009-11-20T11:08:10Z

Continuing with my validation problems, I think I've discovered a bug in how struts2 handles the method invocation after validation.

Here is the submit tag:

<s:form action="ScheduleDetailAction_dontCallMe" validate="true">

and in the struts.xml

<result type="chain" name="dontCallMe">
ScheduleDetailAction_callMe
</result>

If the form associated with the form tag gets validated succesfully, everything works. However, if the validation fails, it tries to call the dontCallMeMethod().

java.lang.NoSuchMethodException: ScheduleDetailAction.dontCallMeMethod()

HOWEVER - if I implement dontCallMe(), then everything works, but the dontCallMe() method is NEVER called.

This seems to be bug to me?

Help needed validating a struts select box

2009-11-20T04:51:30Z

Hi all,

I am trying to validate a select box using Struts 2.1.8. The select box
is a required form element, and by default it is empty. I need to
validate that values have been put into it before it is submitted.

_Struts select box:_

<s:select name="myIds" list="myList" listKey="id" listValue="name"
size="8" multiple="true" required="true" theme="simple" />

_Struts XML Validator:_

<field name="myIds">
<field-validator type="required" >
<message key="this.is.required"/>
</field-validator>
</field>

When I use the above snips, the XML validator does not catch that the
select box is empty.

I have tried using validate() to make sure that an empty select box
cannot be submitted. I could not get this to work. The array I get is
of size 0 and setting the array to null doesn't help me either.

Does anyone know how to do this?

Re: How to check if an iterator is empty inside a s:subset?

2009-11-20T03:15:25Z

Finally I've found that:

<s:if test="#attr.myListIterator.hasNext">

did the trick. The thing is that I wasn't able to figure out where to
find out "var" defined objects. Now I know that are accessed trough
#attr.

I hope it will help those people with a similar problem.

Re: struts.i18n.encoding

2009-11-20T02:51:56Z

Hi Cristian,

Thanks very much for your response.

I am using GlassFish 2.1 so will have a look to see if I can implement
your type of solution. What I don't get is why we need to apply a
filter when already the server is configured to use UTF-8 and we have
UTF-8 defined in the meta for the JSP.

It just seems strange that nobody has got this to work with
struts.i18.encoding. Surely there must be some other people out there
with multi language struts 2 apps.

I will try your solution and keep digging some more.
Cheers,
Carl.

Re: struts.i18n.encoding

2009-11-20T01:58:25Z

In my application also used the 'struts.i18.encoding=UTF-8' but I had
the same problem. But I found a way to get it to work.
This way you are only telling struts that has to use UTF-8. But you
also need to tell to your Applications Container
(Tomcat for example) that you want UTF-8.

1. Set the URI encoding of Tomcat's server.xml configuration file. Set
URIEncoding="UTF-8" in your http/https connectors:


<Connector URIEncoding="UTF-8" acceptCount="100" connectionTimeout="20000"
disableUploadTimeout="true" enableLookups="false"
maxHttpHeaderSize="8192" maxSpareThreads="75" maxThreads="150"
minSpareThreads="25" port="80" redirectPort="443"/>

2. Set a custom filter to configure POST requests use UTF-8:


<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>path.to.your.filter.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Tomcat already comes with such an example filter of SetCharacterEncodingFilter.

3. Also in my application's web.xml I have set that JSPs use UTF-8 as a default:

<jsp-config>

<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<page-encoding>UTF-8</page-encoding>
</jsp-property-group>
</jsp-config>

4. In every JSP you I have the following typical <meta> tag inside <head>:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

I hope it will help.

Cristian.

struts.i18n.encoding

2009-11-20T01:14:26Z

Hi Guys,

I have an app with form fields and when submitting them to my Struts 2
actions the values are getting garbled. For example "españa" becomes
"espa?".

I think the problem is with Struts because when I create a basic jsp
page and submit back to itself and display the form field - it works
fine.

I have tried setting struts.i18n.encoding=UTF-8 in the
struts.properties file and the struts.xml file to no avail. Has anyone
used this with success? I have searched the forums and it seems to me
that people have to resort to custom filters to workaround the problem.

Carl.

struts2 breadcrumb plugin

Hi,

I'm looking for the Struts2 Breadcrumb Plugin by Scott Stanlick. The
published Link to the Plugin at
http://cwiki.apache.org/S2PLUGINS/breadcrumbs-plugin.html seems to be dead
and the site http://struts2inaction.com/ that is supposed to be hosting
the plugin seems to be down.

Does anyone have this file and is prepared to send it to me or is there an
alternative download link?

Thank you!

Strange behavior after upgrade

2009-11-19T15:43:04Z

Hello all.

I have upgraded a Struts 2.0.11 project to 2.1.8, and I have some strange
behavior. The Struts stuff seems to work fine, and the Ajax stuff works
fine as well. The Hibernate stuff works as far as reading data is
concerned. But when I try to write a record, nothing happens on the
database and I get no exception thrown, and I get no errors in the log.

For instance, whenever a user logs in, a LoginHistory object is created, and
subsequently written to the login_history table in Postgres. The
application is using the EntityManager to persist a new object. The code is
simple; the LoginHistoryService class says:

public void persist(LoginHistory loginHistory)
{ try {
System.out.println("About to insert login_history record") ;
entityManager.persist(loginHistory);
System.out.println("Done inserting login_history record") ;
}
catch (Exception ex)
{
System.out.println(ex.getMessage() ) ;
}
}

I see the two logged messages, and in stepping through with a debugger, the
persist statement *seems* to be done, but nothing appears in the database.

Also, when changing a User's account data, nothing winds up in Postgres.
The UserService class says:

public void merge(User user)
{ try {
entityManager.merge(user);
}
catch (Exception ex)
{
System.out.println(ex.getMessage() ) ;
}
}

But the record is never changed.

The Hibernate section of pom.xml says:

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate</artifactId>
<version>3.2.1.ga</version>
</dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.2.1.ga</version>
</dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.2.1.ga</version>
</dependency>

As I sit here pulling my hair out, does anyone remember having anything like
this happen after an upgrade to 2.1.8? Or an any other circumstance?

Thanks,
Tom

Setting Session setMaxInactiveInterval

2009-11-19T07:16:03Z

What is the proper way in Struts2 to dynamically set a particular
application's session timeout value (HttpSession setMaxInactiveInterval)
during the login process so that the session properly expires?

Is this only possible by creating an HttpSessionListener and putting it
in web.xml?

public class MyAppSessionListener implements HttpSessionListener
{
public void sessionCreated(HttpSessionEvent event) {
HttpSession session = event.getSession();
session.setMaxInactiveInterval(60*5);
}
public void sessionDestroyed(HttpSessionEvent event) {
HttpSession session = event.getSession();
Session.invalidate();
}
}

<listener>
<listener-class>MyAppSessionListener</listener-class>
</listener>

Thanks,
Chris

How to check if an iterator is empty inside a s:subset?

2009-11-19T04:04:41Z

Hi,

I'm trying to show a "There are no items in the list" message in my
application. I'm using a subset the following way:

<s:subset source="myList" decider="myDecider" var="myListIterator">
<s:if test="#myListIterator.hasNext()">
<s:iterator status="status">
<tr class="<s:if test="#status.even">even</s:if><s:else>odd</s:else>">
<td><s:property value="%{name}"/></td>
<td><s:property value="%{type}"/></td>
</tr>
</s:iterator>
</s:if>
<s:else>
<tr>
<td colspan="2">There are no items in the list</td>
</tr>
</s:else>
</s:subset>

But I'm not able to find how to access to the subset iterator... to
check if the iterator (or the subset list) is empty.

I'd appreciate any help.

Thanks,
Cris

dojo datetimepicker not invoking setter

2009-11-18T22:39:27Z

Hello,

It seems as though using a Dojo element is not invoking the setter in my
action, and I am not certain why. I hope I am simply missing something?

Struts 2.1.8, Tomcat 6.x, Firefox 3.5.x

I have included the following jars in WEB-INF/lib, and have the following
inside the <head> tag of the action's JSP:
<sx:head debug="true" cache="false" compressed="false"
parseContent="false"/>

Jars:
freemarker-2.3.15.jar
struts2-dojo-plugin-2.1.8.jar
struts2-json-plugin-2.1.8.jar
json-lib-2.1.jar

Using s:textfield tag invokes the setter as expected; however, using
sx:datetimepicker and <sx:head> tag does not invoke setter.

<s:textfield name="addMeasurementDate"
size="10"
maxLength="10"
value="2009-01-01"/>
<%--<sx:datetimepicker name="addMeasurementDate"
displayFormat="yyyy-MM-dd">
</sx:datetimepicker>--%>

HTML produced when using <sx:head> and <sx:datetimepicker>:

<td class="dateRowOdd" nowrap="nowrap" align="left">
<div
dojoType="struts:StrutsDatePicker" id="widget_631437215"
name="addMeasurementDate" inputName="dojo.addMeasurementDate"
displayFormat="yyyy-MM-dd" saveFormat="rfc"></div>
<script language="JavaScript"
type="text/javascript">djConfig.searchIds.push("widget_631437215");</script>
</td>

JavaScript entries are present in head tag, and in Firefox's View Page
Source I can click on them and access the JavaScript source.

Action contains:

public void setAddMeasurementDate(String addMeasurementDate) {
System.out.println("----- Date: `" + addMeasurementDate + "\"");
this.addMeasurementDate = addMeasurementDate;
}

I tried nesting the s:textfield inside the sx:datetimepicker tag as well,
but setter is still not invoked.

I can't seem to find any useful information about this issue. I have tried
<s:submit> and <sx:submit id="..."/>, with the same result (setter not being
invoked) (and sx:submit does not refresh the page, but does invoke
execute()).

Any help is greatly appreciated.

Thanks,
Lee

s2: validation of checkbox a radio button

2009-11-18T17:27:44Z

Hello,
I am trying to use client side validations through ...-validation.xml in struts2
I have it working but only for text and file input fields. I need to validate if a checkbox is checked. using "required" or "requiredstring" validators always validates as the field as a value even if you don't checkit. I guess the same happens with a group of radio buttons. (all with the same field name). They have a value.

I have not found a OGNL expression that might work.

Anybody know how to solve this? I'd like to use simple client side validation.

Thanks,
Ignacio

Re: s2: Validation xml file not being used when validating a method

2009-11-18T13:58:38Z

Apparently it isn't working as I expected. I would really like to understand how this works.

Here is my form tag:

<s:form action="ScheduleDetailAction_updateSchedule" validate="true">

Here is my struts.xml entry:

<result type="chain" name="updateSchedule">
ScheduleDetailAction_update
</result>

Here is partial contents of my ScheduleDetailAction-ScheduleDetailAction_updateSchedule-validation.xml

<field name="schedule.count">
<field-validator type="required">
<message>Count is required</message>
</field-validator>
<field-validator type="int">
3
30
<message>Count must be an integer between 3 and 30</message>
</field-validator>
</field>

and I have an update() method in my ScheduleDetailAction.java file.

Here is the problem:

If I enter an integer, the validation is checked and the form works correctly. If I enter a String, for example, I get this error:

NoSuchMethodException: ScheduleDetailAction.updateSchedule()

Why does it honor the struts.xml and redirect to the update() method when the input is correct, and why does it look for a non-existent method called updateSchedule() otherwise?

Thanks in advance.

Are you talking about two submits on the same form? That is definitely possible.

Lazy Initialization Error

2009-11-18T13:24:18Z

I am trying to understand why my web application throws a
LazyInitializationException when trying to lazily initialize a
collection in an entity object.

From what I have read, I needed to setup a filter for Hibernate in my
web.xml and since I am using JPA the filter was defined as follows:

<filter>
<filter-name>hibernateFilter</filter-name>

<filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInVie
wFilter</filter-class>
<init-param>
<param-name>entityManagerFactoryBean</param-name>
<param-value>entityManagerFactory</param-value>
</init-param>
</filter>

And then the mapping was set as follows:

<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

// LoginAction.java
public String execute() {
User user = userService.authenticate(userName,password);
if(user != null) {
setSessionObject(Constants.USER_KEY, user);
return Action.SUCCESS;
}
return Action.ERROR;
}

When a user is at the login form and the LoginAction execute() method is
called, the user object is instantiated properly from the user service
and contains all the eagerly pulled values. I then click on another URL
which calls another action's execute method that does the following:

public String execute() {
User user = getSessionObject(Constants.USER_KEY);
if(user != null) {
if(user.getUserRoles().size() > 0) {
// do some other stuff
}
}
return Action.ERROR;
}

The problem is when getUserRoles() is called, I get the error because
they are not pulled eagerly when the User entity is first fetched from
the database. Is there a way I can avoid this
LazyInitializationException problem?

how to use one user input in two forms?

2009-11-18T13:10:22Z

Dear all,

I want to use a multiple select to ask user select the item they want. The items selected will be on a pdf file which will be sent as attachment of email (user can click "send email" button to send them). The user wants to confirm if the pdf is right before he sends it. Therefore, I create a "PDF" button to ask user to check if the PDF attachment is what he wants to send.

Here is the situation:
Since the "PDF" button and "send email" button will both use the selected item info, I don't want the user to select the same list twice(of course user doesn't want to do that).

I thought to store the selected info in session when the user click "PDF" so that they have the info when he clicks "send email". But user may just click "send email" directly without checking first, then the selected info will be lost.

Any suggestions about this? Thanks

Re: Question about objects in a JSP

2009-11-18T12:29:51Z

By 'old struts', I'm assuming 1.x ...

In our application, our application sets values into the request with request.setAttribute("varName", var) and then references the variables in the jsp with (for example) <c:out value="${varName}" />

Then you can use the <c:if/> tags etc,

Not sure if I answered your question...

Re: Getting Context within

2009-11-18T08:30:36Z

Something like the following should work (double-check the syntax though!):

<%@ page import="com.oe.wa.cal.bean.DownloadBean" %>
> <%
>
for (DownloadBean db: (List<DownloadBean>)
request.getAttribute("downloadList").iterator()) {

> out.print(db.getSomeProperty());

}

Getting Context within

2009-11-18T07:22:37Z

Hi,

So I think I have a better way to ask my question ;-)

Given something like this block of tags:

<logic:iterate id="download" name="Downloads">
<bean:write name="download" property="displayName"/><br />
<bean:write name="download" property="description"/>
</logic:iterate>

How can I do something like this inside the <logic:iterate/>:

<%@ page import="com.oe.wa.cal.bean.DownloadBean" %>
<%
DownloadBean db = (DownloadBean) request.getAttribute("download");
out.print(db.getSomeProperty());
%>

Note that I want to do this with a scriptlet and not with tags.

Thanks!

Jon

Struts in Action is for the Struts 1 series... I think the OP would be
better learning Struts 2 from the book "Struts 2 In Action" available
here -

http://www.manning.com/dbrown/

More recently, Dave Newton's book has been getting good reviews as well -

Rupesh,
Probably you can try this with Apache HttpClient.
