Where to disable encrypting of non latin chars?

2009-11-26T19:17:30Z

I just have found another issue after upgrading from [2.1.6] -> [2.1.8]. Struts now encode any non latin char to its HTML entity of property.

E.g. now I have such a mess in HTML output (in browser it looks OK):
описание

How to disable encoding of every char but leave only encoding of special chars like?:
< > ' "

You could write your own value stack that extends the OGNLValueStack
and just hacks the property name to make it the right/wrong case, but
oh boy does that scream trouble :)

What an amusing thread. It seems to me the only problem here is the arrogant

Well, yes, i am getting paid for this. So the time that i need to rename
the methods costs my employer big money.

This is a case of true backwards incompatibility and causes trouble in
non-trivial projects such as ours. Other projects may decide to not
upgrade from earlier Struts versions to V 2.1.8.1, which is something i
would definitely take serious if i were working without getting paid,
because having your stuff used by as many people out there as possible
is a major point of FOSS, right? Freedom of choice is the other, meaning
that we could of course stick with V2.1.6 and patch it to our liking. I
personally voted against the latter option and decided to go for the
renaming option because we need some other fixes that are available in
2.1.8. And, to tell the truth, our choice to use "getmProperty()" as
accessor method naming pattern was a bad one originally but we lived
with it since the beginning and are now being bitten in the behind :-)

Please don't try to make us feel guilty :-)
You'll get paid for this, we're not.

In previous post I stated clearly: "If the only problem is the number
of methods to be changed"
not "If you can change only some classes".

jEdit should be powerful enough to open each java file in project
directory, find all strings matching regex:
([sg]et)([a-z])Property\(
replace it with:
$1\u$2Property\(

This should work for both getters and setters and make first character
upper case, assuming you have get[1character]Property() pattern.

All this in one step.

Use of hashcode as ETag in Rest plugin.

2009-11-26T07:44:15Z

Hi,
Rest plugin's DefaultHttpHeaders class uses hashCode of the model object (if the action is model driven) or hascode of the action object.I guess its a wrong assumption to make that two different objects will have different hashcodes. So we can have same hashcode even if model objects are not equal and that will wrongly send 304 response even if resource is changed. Is this a known bug in REST plugin?I have also posted this on struts dev mailing list.
Thanks,Unmesh

2009-11-26T07:41:44Z

Well, i was hoping for an interceptor-based solution. But since
something like this apparently is unavailable, i'm going for the method
renaming approach, which is tedious work because i'm only changing the
classes that are used by the Struts2 part of our codebase. So a global
search/replace approach will not work, i have to go through each
applicable class and refactor-rename each method.

Hi Robert,
maybe not in one step,
but for sure it's pretty easy to do.
Just look for "public [^ ]+ get[a-z]" regexp in your codebase, and
eclipse will do the rest,
plus there's a bonus, You don't need to change anything in your jsp files.
Ant to be absolutely sure everything worked well
simply run all your tests after the refactoring.

But of course it's for You to decide what to do.

I would think that is a feature of Struts that it requires proper OOP names.

Hi,

we do of course use a refactoring tool, but we are talking about a huge
amount of methods. I'm not aware of a refactoring tool that would allow
me to rename *all* methods in *one* step.

In Java Action Bean you would just have to return a specific string that
struts.xml uses.

Instead of programmatically doing it, you can just specify redirect in your

Hi
If the only problem is the number of methods to be changed, maybe you should consider using a refactoring tool.

-you do that only once
-your code is kosher
-you don't get performance overhead introduced by another interceptor

RE: Preserving Messages and Garbage values Across a Redirect in Struts 2

2009-11-26T05:13:15Z

Messages are stored since you use RedirectMessageInterceptor.

Action property Data is not retained during redirect.

Try following scenarios,

Method1:

So you need to set explicitly from Action property to ActionContext in
Action1 and Need to retrive from the context and set to properties in
Action2.

Method2:

Try to use alias interceptor and put alias through the <param> tag in
struts.xml of Action1 and Action2 properties as below.

<param name="aliases">#{ 'action1Property1' : 'action2Property1',
'action2Property2' : 'action2Property2'}</param>

<interceptor-ref name="alias"/>

Method3:

Have you tried chain instead of redirectaction and use same properties in
Action1 and Action2.

Subject: Re: Preserving Messages and Garbage values Across a Redirect in
Struts 2

I donno If i can able to explain it to you, I will try my best , here is
the

secinario

Step 1. When the user click the button on the page, depend on the string

return from the action method the page will be display and is configured in

the struts.xml file as mention below.

<action name="determineCaseEvaluationType"

class="com.activity.EvaluateCaseAction"

method="determineCaseEvaluationType">

<result name="guidelInitConsid"

type="tiles">editGuidelinesCaseEvaluation</result>

<result name="shrtsntcInitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

<result name="sscat2p1InitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

</action>

step 2. There are fields in the pages like 10 text boxes 2 drop down and 2

radio buttons , when I fill all the field and click submit it will do the

neccessary business operation and return the string to which page is to

display, and is mention in the struts.xml file as mention below

<action name="saveInitConsiderationEval"

class="com.activity.EvaluateCaseAction" method="saveInitConsiderationEval">

<interceptor-ref name="redirectInput"/>

<result name="success" type="redirect-action">

determineCaseEvaluationType

</result>

<result name="input" type="redirect-action">

determineCaseEvaluationTypeForInput

</result>

</action>

step 3. : when valiations fails I need to determine on which page

validations failed and hence I am forwarding the the input to method which

it will determine what page to be displayed.

<action name="determineCaseEvaluationTypeForInput"

class="us.ga.state.pap.cons.clemency.presentation.action.activity.EvaluateCa
seAction"

method="determineCaseEvaluationTypeForInput">

<result name="guidelInitConsid"

type="tiles">editGuidelinesCaseEvaluation</result>

<result name="shrtsntcInitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

<result name="sscat2p1InitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

</action>

I hope you got the sicenario , Its tofugh to explain whatz going on in the

mind !

Thanks

Siddiq.

Re: Struts 1.1 To Struts2.x Migration

2009-11-26T05:08:11Z

I suggest first try to migrate a small project to 2.1 from 1.x and then move
to your production application.

If you want a sample 2.1 application, you can get it here
http://code.google.com/p/startsoft/ (It has some bugs)

S2 2.1.8.1: Need custom decapitalization (or leniency similar to 2.1.6)

2009-11-26T03:48:30Z

Hi,

we are currently in the process of evaluating if upgrading our app from
Struts 2.1.6 to 2.1.8.1 is feasible. Currently it is not because various
things stopped working, but i'll like to work on one of them at a time.

We frequently (*very* frequently, actually) use property names such as
"mProperty" which are to be bound to class member variables of the same
name and get/set via methods called "getmProperty" and "setmProperty".
This practice deviates from the JavaBean rules for property access, i.e.
in this example, the getter would have to be called getMProperty and the
setter setMProperty (each with a capital M). Struts 2.1.6 was able to
map the property "mProperty" to calls to getmProperty and setmProperty,
respectively. Struts 2.1.8.1 apparently does not have this leniency (or
faulty behavior, depending on your POV...) and behaves strictly
according to what Introspector.decapitalize() does.

Since we (obviously) don't want to rename the myriads of
getters/setters, i'd like to know if there is a way around this, maybe
with a custom interceptor somewhere?

Robert

Re: "Struts2 + Spring + ibatis" vs. "Struts2 + Spring + Hibernate"

2009-11-26T02:03:29Z

I dont have a production server running Struts2 and iBatis.

I have however worked with iBatis and some other Web Presentation Framework
and I have researched on this extensively too. The bottom line is to go with
iBatis when you are working with existing database application and Hibernate
when new database is made.

Error Messges(Field Validator Type = regex)

2009-11-25T23:46:41Z

Hi Friends,
        I am using struts 2.1.6. Facing problem with error messages.
When i use 'regex' validator in validation.xml file than
1. when i clicked on submit button for the first time.
       It is showing error messages like
                 Customer name is required.
                 Allow alphabets only.
the above message 'Allow alphabets only must show when some invalid data enter in the field other than alphabets.
2. with out entering data again i clicked submit button.
than know error messages are
Customer name is required.
Allow alphabets only.
Customer name is required.
Allow alphabets only.       Repated twice.
if i clicked again thrice.........
And my code in xml file is, and using default theme

<field name="customer.name">
    <field-validator type="requiredstring" short-circuit="true">
      true
      <message key="error.cusname.req"></message>
    </field-validator>
    <field-validator type="regex" >
            <![CDATA[(^[a-zA-Z ]+$)]]>
        <message key="error.cusname.fv"></message>
    </field-validator>
   </field>
if i remove regex than it is working fine.
Could u tell me how to reolve this issue.

Thanks,
Taj

Ya thats true, but its not clean such as the way used in spring, or JSF
managed beans. lookup service is a another dependency for your project.

Why is it a challenge accessing EJB in Struts2? All you need to do is to
lookup your local or remote EJB interface, which is in fact 1 line of
code.
Joachim

Struts2 is good for your presentation layer. It is the MVC front
controller.
Accessing EJB is a kind of a challenge inside Struts2 rather than spring.
Struts2 + spring + hibernate will be a good combination if it is suitable
for your problem domain.

Struts2 is good for your presentation layer. It is the MVC front controller.
Accessing EJB is a kind of a challenge inside Struts2 rather than spring.
Struts2 + spring + hibernate will be a good combination if it is suitable
for your problem domain.

Re: Is Using Spring With Struts 2 A Good Idea?

2009-11-25T09:13:42Z

Thanks to everyone who has replied so far.

Your input is very valuable as we evaluate using Struts 2 and Spring together.

Wes - thank you for the feedback on some areas of concern when using Spring. Teaching our other Java developers how to use Spring is an issue. I do think there are now several good online sources for helping others learn to use Struts 2 and Spring (I do wish the Struts 2 book you started that included a nice chapter on Struts 2 and Spring would have been published. I got the early access version and it was a big help in learning how to use Spring with Struts). I've also tried to write up some good articles on my blog.

Once you get past the learning curve - I've found that using Spring speeds up my development and also makes my application easier to test/enhance/change in the future. Does anyone disagree with that?

Please keep the feedback (both good and bad) about using Struts 2 and Spring coming.

Thanks again.

Bruce Phillips

Bruce, I am currently working on a commercial product that combines
the two. I could sing songs of praise, but I figure you've already
gotten a few of those messages, so I will try to come up with a few
drawbacks I've noticed.

One thing I noticed early on is that it seriously compounds the amount
of XML configuration you will have to manage. I am a fan of the
Conventions plugin, but still feel obligated to stick to traditional
(explicit) configuration for projects of serious size. I just deployed
an app recently at a customer that contains 1678 lines of XML
configuration just for struts and spring (this does not include
sitemesh, web.xml, maven poms, etc.).

Another thing I noticed is that this (these) project(s) now require a
significant learning curve. I think most of the people on this list
wouldn't be scared to jump into a project using struts 2, spring, jpa,
maven, etc. But... In my neck of the woods (just north of Kentucky,
but not a whole lot more civilized), it is difficult to find trained
Java professionals who are fluent in the technologies named above.
What is interesting is that when you look at the code, on a per source
file basis, it is all very simple (POJO-based development with simple
services/implementations). However, conceptually fitting all the
pieces together always tends to fall on my shoulders since my team
tends to be less experienced in the different libraries.

With that being said, I will add that it really is a pleasure to use
all of these things together. After a certain point in every project,
development time speeds up drastically. Changes are easy and a nice
library of components is created that allows for easy additions. All
of these things tend to come together once you get past the first two
points above.

I've been using it for over 50 projects with excellent results. Once you
start using spring in big projects you really can't go back.

RE: Is Using Spring With Struts 2 A Good Idea?

Hi Bruce,

First off I think I have definitely used your blog in the past, I just
want to is has been very useful.

Now I would imagine the question you asked will lead to some very
interesting answers that I look forward to reading. However on the
whole, I don't think it could be class as bad practise using Spring,
unless the size of your application isn't big enough to warrant it, but
then if that was the case would you still use S2?

I love Spring, I am a big fan of the coding by interface and decoupling
of layers. I have fallen into (maybe a trap) the routine of using Struts
(1/2) with Spring and Hibernate JPA. I find this a nice complement of
tools and pretty much allows me to accomplish majority of what my web
application sets out to do.

For example and app I writing at the moment I am using

Struts 2
Scriptaculous/Prototype
Spring 2.5.5
Hibernate JPA

I like splitting my application into layers of

Actions
Service
DAO

However with the light of the entitymanager a DAO is fast becoming
slightly redundant as most of my DAO methods consist of one line.

The beauty of Spring with transactions is the ability to mark out a tx
boundry with simply using the @Tranactional annotation on the service
method. This also allows for encapsulation (I hope I have the right OO
term here) as you can this to the DAO methods but mark it as saying a tx
is required and would fail if a tx isn't open.

There is also stereotyping which allows you to mark classes as Service,
DAO (actual @ is repository) or Controller (if you are using Spring MVC)
this can lead to a more refined autowiring as well as pretty much
eliminating the need for XML configuration. I personally use
stereotyping for exception translation from the entitymanager (look for
DataAccessException) this allows for a cleaner Service layer.

I have also use Spring in conjunction with EJB's either looking up an
EJB an injection into a POJO or injecting a POJO into an EJB - Very
useful when coming across legacy projects...

Spring is such a huge project and I don't think I have even used the tip
of the ice berg.

I hope this helps...

James

Subject: Is Using Spring With Struts 2 A Good Idea?

At the University of Kansas (#1 college basketball team :) we use Struts
2
for our web application framework. Its worked very well for us.

I've been learning the Spring framework and how to use it with Struts 2.
I
think the two frameworks work very well together.

I'm preparing a class for the other Java developers on how to use Struts
2
and Spring together. As part of my research I'd like to hear from other
Struts 2 developers on if you use Spring with Struts 2 and if you think
its
a good or bad practice.

Thanks in advance for any feedback you can provide on why or why not
it's a
good idea to use Struts 2 with Spring.
