Hi,

I made a small webapp, where I am able to store some sports training data. In my webapp I have some text fields, which provide lookup functionality via prototype-window by xilinus and loads the lookup content via an iframe (for not having to reload the full page but only the lookup content).

My problem is, that I see the lookup window, but I can only partly interact with it.

eg. I cannot close it via "x" button or type some text in the input field in the iframe.

So is there a way, to do some "cool looking" good working lookup functionality?

greez and thanks for any hints, Manuel

Sorry for not answering sooner.

We tried to reproduce this error (local with a stress test and in a Test Environment) but we were not able to reproduce the error.

We have the following problem in our WebSphere Server:

When out users submit an order, they get sometimes an exeption page. The WAS Logs show the exception below.

Has anyone any idea what the problem could be?

Some infos:
The application is a java struts app with iText, spring and hibernate (middleware, separated). The WAS version 6.1.0.5 is running on a Solaris machine and before is a F5 Loadbalancer with HTTPS
We had no deployment, it seems that this had just started sometime ago.

If you need more info please just ask.

Thanks for any help in advance.

greets, Manuel

Hi!

I have an application, which is developed in JBoss and deployed in WebSphere.

In WAS we use the ResEnv-Entries to set some configuration variables, and in JBoss we use some xml files in the application.

When in WAS some config vars are missing / have typos, the application takes the xml files. Now no error occurs, but the application might connect to a test database, instead of the production.

So I would like to remove the xml files from the application, and have all config only in the Application Server.

Is there any technique in JBoss simmilar to the ResEnv-Entries?

Hope anybody can help me.

Thanks, Manuel

The problem is, that you define the JPanel in the constructor, if you would define it as member variable you would not have that problem.

But actually I can't give you an answer why it behaves like this.

But in general it is better practice to make member variables and create methods, not compute everything in the constructor.

Just create 2 appenders (1 file, 1 stdout), this should be working fine.

If you need more help, it will be useful to know how you configure log4j (property file, xml file, in Java code).

Hi Ronald!

You could just have a variable in your form bean and set this to true in your action and in the jsp / facelet you have an

1. You could try MyEclipse (you have to buy a license) or RedHat Dev Studio (free) or look at eclipse-plugins.2y.net or at www.eclipseplugincentral.com for plugins.

2. It depends what exactly you want your projects to do, but I would say, in most small / middle sized projects you won't need JNDI, JMS, WebServices, XSL ...

3. I don't know EJB, but hibernate, and it is really easy to understand and use. It may be an asset to understand EJB, but you can do with hibernate only as well.

Hello Amit!

Which display technology are you using? (facelets or JSP)

I would prefer your second solution, I think it is much more straightforward.

Just create one Bean thats session scope with all attributes you want, then you are able to store them directly and type safe, whereas when storing directly in session you have no type safety at compiling time, because you could throw everything in.

Hello!

I want to make a weekly scheduler, so I can input some entries (i.e. Tue 12:30-14:00 programming, ...)

I am not sure how to implement the display of one week with all entries in it.

I have an Object WeeklyScheduleEntry, which holds one entry. I implemented a method which gets me a List<WeeklyScheduleEntry> but I do not know how map this list into a JSF table component.

My table component would have to have a fixed size "weekdays x hours per day", and in that table I want to show the (optional) entries.

I have tried some different approaches but none of them really satisfy me.
(I did not try a custom component yet cause of lack of knowledge ;) )

I am using myfaces and facelets for this project.

Any help is very appreciated,
Manuel

Just a guess, but I would look in the namespace configuration (facelets) / in the taglib definitions (JSP).

Hello Kilia!

First of all: a JSP is compiled to a Servlet, so JSP is only a special way of writing servlet. It should make it easier to split up GUI from business code.

You should learn first of all Servlets & JSP, which will give you a basic knowledge of what happens in a dynamic web application.

Then I would either lern EJB or directly struts or JSF.
