Re: Javascript(?) Spreadsheet

2009-10-26T05:11:02Z

Hi Dave,

Yeah, the commercial Javascript grids or spreadsheets put a lot of work
into detecting the browser and acting accordingly. You still have to
worry about new releases, but since you control the Javascript, you can
easily update it when the vendor comes out with a fix.

I used one of the Javascript grid kits in a project about 5 years ago,
but my experience is probably outdated now. It worked well and looked
good, but the learning curve to do what I needed was a little steep.

They typically obfuscate their Javascript code, so making small
modifications to their code is a big headache. Sometimes you ca pay
more and get the Javascript code in un-obfuscated form. That is
something to look for in whichever kit you choose.

For your project, you might just want to use that and a servlet to
implement your project.

Rick,
Thanks for the info. To answer your questions:
I'm expecting that as many as 1000 users could be using the web app/service at the same time. That's my baseline requirement, anyway.

Most of the data is numeric, with a couple of text and an image.

The numeric data is highly interdependent, but individual calcs are mostly quite simple. Changing one value CAN invoke a cascade of most of the calcs, some several times.

By "state", I mean things like user-specific data, program mode, current data values.

Perhaps the above makes it more clear why I'm even considering client-side scripting, but I understand what you're saying about browser-based dependencies (even if I don't understand WHY that has to be the case!).

I've seen components like BlueShoe's javascript spreadsheet, but haven't used them. I would think such would be less sensitive to the particular browser, since they should be well tested - one can hope.

Would be nice to know what others' experience has been.

Dave

Browser based solutions can be a pain because 1- All the browsers run
Javascript differently, 2- All browsers have different syntax for
Javascript, 3-Developing large apps with scripting languages is a
debugging nightmare, 4- You generally can't control which browser or
version of browser the users employ.

With 1,000 users the transaction rate shouldn't be that high, unless its
an app that all 1000 are using simultaneously.

50 data items is not that much unless some are images or something like
that. 50 text item at 20 characters each is less than 1K of data.

When you say 100 calculations, are those done all at one on a page
submit or does changing cell A affect the value in cell B?

If the latter is the case you can set up the page as a grid of text
boxes (or maybe pull down menus for items that have a fixed, finite
number of values).

You can use Javascript to do simple, easy to debug calculations to put a
new value in cell "C" if "A" or "B" change.

That avoids the 2 second or so delay that you would get if you use JSF
to do that. That can be a real pain if you are futzing with 50 boxes
that update after each change.

When you say state is important, what exactly do you mean?

Javascript(?) Spreadsheet

2009-10-25T14:17:51Z

All,
I'm developing a web app that:
1) Has a good bit of data, say 50 items, that the user can futz with.
2) About 100 small calculations; and state is important.
3) Sessions last longer than a minute, and 5-10 minutes wouldn't be unusual.
4) Expecting 1000+ users.

Now, #'s 1 and 2 suggest I want to minimize server transactions. #'s 3 and 4 tell me I don't want to suck up a lot of server resources.

A javascript (or other?) spreadsheet solution sounds like a reasonable possibility. I'd like to know what others have done in similar situations, and, if a browser-based spreadsheet solution is the right answer, what products you've used and would recommend.

TIA,
Dave

Calendar control shows duplicate dates

2009-10-25T09:42:39Z

I have a visual web app running in NB 6.7.1 that uses the Woodstock calendar control. When the month is set to November 2009, the control displays November 1 twice. Which then throws off the entire calender with respect to the day of the week for any given date.

I suspect this has something to do with daylight saving time, which reverts to standard time on November 1.

An example of the problem can be seen at http://webdev2.sun.com/example/faces/calendar/calendar.jsp
Set the month to November and observe that November 1 shows up as Sunday and Monday.

Any help would be appreciated.

The jsp for the control is as follows:

<webuijsf:calendar binding="#{AddRequest.startDateCal}" id="startDateCal" selectedDate="#{SessionBean.startDate}"
style="font-family: 'Arial','Helvetica',sans-serif; font-size: 14px; font-style: normal; font-weight: bold; left: 280px; top: 232px; position: absolute" tabIndex="3"

Reference problem--"jsf12-support library could not be found"

Maintaining deployed app

2009-04-27T13:04:48Z

I figure we're all here developing, deploying and maintaining web apps, so...

My dev system is not my server system (duh ;) ), so I deploy to the server remotely using the Glassfish admin web app. Very cool.

However, I can't seem to figure out how to maintain the backing database. I like to use Squirrel SQL for doing database maintainance, but the server refuses the connection. I'm sure I have to open port 1527 on the router, but it seems I also have to tell the Derby and/or Glassfish server to allow an external host to connect. So maybe some of you have some common means of:

1) Backing up the database remotely, to my dev system's local drive. Of course, I'll need to re-deploy/restore the database once my changes are made. Setting up Squirrel to do this would be cool, but I'm open to other options.
2) Putting up a "Server will be/is unavailable" notice when I need to redeploy the app or update the database.

This seems pretty basic stuff, and maybe I've worked too many 20-hour days to figure it out on my own (I've tried). A good URL will do, or SQL and/or Java snippets. Whatever.

One other thing. My server runs ubuntu hardy. To start the database server, I use asadmin start-server on the command line. No, I don't want that to be automated - the server is still 'beta'. But is there a way to do this within the Glassfish admin web app? I've seen stuff about JDBC connection pools, but I haven't set one up (to my knowledge, but maybe NB did when I wasn't looking), so I don't know if start/stop is a Glassfish console capability.

TIA,
Dave

Re: Table Pagination when Navigating to Page

2009-04-25T08:38:00Z

The table "remembers" the last paginate setting. If you display all the rows in the table, navigate to another page, then navigate back to the first page, the table will display the rows based on the last paginate setting.

Okay, temper's settled, so a bit more detail on the 'solution'.

I, uh, didn't really notice that no matter which menu button I clicked, I was seeing the SAME page, which does NOT have/need pagination. <groan> All the buttons returned 'case1'. Get it now? Change the handlers to return the correct 'case#', and things work fine.

Re: Displaying lots of data

2009-04-23T06:04:59Z

For (1) you can configure the table for multiple pages. In the table's properties window, make sure the paginateButton checkbox is selected. If you want the user to have the option to display all rows, you can make sure the paginateButton checkbox is selected. (I don't recommend doing this if the table could potentially contain 100s or 1000s or records.) To set the number of rows to be displayed, set the table's row group component's rows attribute to 5 or 10 or whatever.

For (2), I recommend including a button or radio button column in the table and only displaying a few "key" fields from the table. When the user clicks the button or selects the radio button, the record's details can be displayed.

You may find the following links useful for handling buttons or radio buttons in a table component.

click on hyperlink1 - action sets request bean variable with the hidden field value and navigates to page 2 in new window.

works fine the first time.

however if the page1 dropdown value gets changed the hyperlink1 action is repeated - displays page 2 in new window with the new value.

this continues as i keep changing the dropdown.

Any ideas?

Instead of Design view, source view of the page opens when a ".jsp" file is created.

I am using NetBeans IDE 6.1 (Build 200901051526)

Can someone help with this issue?

Please see the image below..

How do I access textField component using javascript in netbeans6.5

2009-01-17T21:02:41Z

I write a simple javascript function as the following

document.getElementById('form1:textField1').value = "hello";

But the textfield shows nothing in netbeans 6.5.
The above code works fine in netbeans 5.5.1.

I already added binding property to both form1 and textfield1.

How to access textfield using javascript in netbeans 6.5 ?

Thanks a lot for your response.
My problem was solved by upgrading woodstock component.
This is a bug of woodstock component come with netbeans.

Hi,

I don't see this using FF 3.0.5 in a simple test with 6.5 and woodstock
4.2 version however I don't know exactly what you have in your project.
I'm not sure if upgrading your woodstock version will solve issue as
was similarly posted in this thread on old Creator forum:

Another alternative would be to migrate to ICEfaces

Weird problem with Firefox 3.05 on Windows

2009-01-12T04:42:31Z

I created a simple Visual JSF Project with several pages.
The problem is every time I go to new page it shows only blank page.
I have to refresh page every time I change page.
This kind of problem happen only on Windows (I test on XP)
but working fine on Linux (Ubuntu).
The browser I use on both OS is Firefox 3.05.

IE 6 is working fine on XP.

Any suggestion?

Thank in Advance

Re: How to Bind an Entity Bean to a DropDownList

2009-01-07T15:44:17Z

After poking around (NB team there is very poor documentation for this) I crafted a solution...

First off, let me say that I am not using the non-stylable WoodCrap DrowDownList component. Rather, I am implementing a Standard DropDownList.

I pulled my lookup table values in ServletListener.contextInitialized() and stored those values as an arraylist of SelectItems in the ServletContext to save on Session bloat:

<code>
ServletContext sc = event.getServletContext();

// Global Db data cache in VM
Coordinate coordinate = new Coordinate();
coordinate.Initialize();

// Countries
List list = (List<Lookup>) coordinate.getCountryLookups(); // see entity manager above
ArrayList CountryAL = new ArrayList();
for (int i = 0; i < list.size(); i++) {
Lookup lookup = (Lookup) list.get(i);
CountryAL.add(new SelectItem(lookup.getLookupid().toString(), lookup.getValue()));
}
sc.setAttribute("countries", CountryAL);
sc.setAttribute("default country", "237");
</code>

Secondly, I created get properties in my page fragment:

<code>
public ArrayList getCountries() {
FacesContext fc = FacesContext.getCurrentInstance();
return (ArrayList) fc.getExternalContext().getApplicationMap().get("countries");
}

public String getDefaultCountry() {
FacesContext fc = FacesContext.getCurrentInstance();
return (String) fc.getExternalContext().getApplicationMap().get("default country");
}
</code>

Lastly, I did the binding using the page fragment design object tree view...
1. select the DDL > right click > Property Bindings > select DefaultCountry as the binding target.
2. expand the DDL. You now see the f:selectItems name (mine is called ddlCountryItems).
3. select the Items name > right click > Property Bindings > select countries as the binding target.

If NB acts buggy save, close, reopen, clean and build.

Compile and life should be all good. I hope this really does help out someone.

Thanks,

Chris

How to Bind an Entity Bean to a DropDownList

2009-01-06T20:02:00Z

Environment: NB 6.1, Vista OS, MySql 5.1, GlassFish.

Over the past day I have sought clear direction as to how to bind a JPA entity bean to a dropdownlist. I examined the following Nabble links for assistance:

http://www.nabble.com/Visual-Web-Designer%3A-Bind-an-EJB3-entity-bean-to-a-dropdown-list-td14888317.html#a14920128
http://www.nabble.com/Dropdown-list-of-user-tp11783679p11801513.html

Here is what I have done thus far:

<entity bean>
I used the IDE to auto-gen the POJO entity which is a simple lookup table in the Db:
id unsigned int,
domain varchar(50)
value varchar(255)
</entity bean>

<in an entity manager>
public List getCountryLookups() {
Query query = _EM.createNamedQuery("Lookup.findByDomain");
query.setParameter("domain", "Country");
return query.getResultList();
}
</in an entity manager>

<entended an ObjectListDataProvider>
public class CountriesDataProvider extends ObjectListDataProvider {

private static ArrayList _ArrayList;

public CountriesDataProvider() {
if (_ArrayList == null) {
FacesContext fc = FacesContext.getCurrentInstance();
_ArrayList = new ArrayList();
_ArrayList.add((List<Lookup>) fc.getExternalContext().getApplicationMap().get("countries"));
setList(_ArrayList);
}
}
}
</entended an ObjectListDataProvider>

<getter and setter in page fragment>
private CountriesDataProvider _Countries = new CountriesDataProvider();

public CountriesDataProvider getCountries() {
return _Countries;
}
</getter and setter in page fragment>

Now this is where things get hazy... I have binded the dropdownlist to the getcountries property - but the rendering didn't work.

So my questions are:

1. Bind to the selectItems node?
2. Is there a better method for binding an entity bean to the ddl?

Thanks,

Chris
