Collaborate on GUI(JSP) level among different J2EE apps with different context root

Mon, 12 May 2008 15:39:08 MDT

What are some of the best practices for sharing data in the GUI (JSP) level among different J2EE apps using different context root.

Portal would be a potential solution. But if Portal cannot be utilized, what are different approaches?

It is a lot easier to share data in business tier. But interested in knowing what can we do in GUI tier for doata interchange among multiple apps?

Calling remote services from a portlet service

Tue, 6 May 2008 16:52:50 MDT

This is one of those questions that I'm pretty sure I know the answer to, but have to ask anyway because I don't really like the answer!

In WebSphere Portal V6, if I want a portlet service to call an EJB or a Web Service, I'll have to modify wps.war's web.xml to add the references, correct? I know that it is possible to call a Web Service without externalizing the endpoint or credentials, but that isn't really good design in my opinion.

So is that it? If you want to call an EJB or WS, you HAVE to modify wps.war's web.xml? Have people done this and had good/bad experiences? From what I've read, modifying wps.ear isn't forbidden, but it's kind of a "enter at your own risk" decision.

Any help would be greatl...

Arabic language support in Portlet

Sat, 3 May 2008 02:44:30 MDT

Hi
I have developed the Email portlet and datas are returned from webservices. In my .java file, I have the variable messageo[1] which returns the email title and title may be in English or Arabic.

When variable has English message then it works fine for me but when variable has Arabic message it displays title like "???????" and I tested like s.o.println() also it's displaying like only "???????" in console.

If I test the Webservices(.wsdl file) then it's displays Arabic message, I think problem with my .java file because it's not reading Arabic message in .java file.

I tested the code like below but it's not working in both case.
In java
String value = new String(messageo[1].getBytes("I...

Web Clipping a relative url

Tue, 29 Apr 2008 21:58:20 MDT

Hello. I am trying to create a portlet with the WebClipper portlet in WebSphere Portal 6.0. When I enter the URL to be clipped, I would like to enter a relative url, that way as I migrate the configuration up through the test environments (which all have different domains), I don't have to touch the portlet's configuration.

When I try this, I get an error because the URL is "malformed" i.e. not absolute. Has anyone ever created a Web Clipper portlet with a relative url?

Thanks!

accessing database from webserver

Thu, 24 Apr 2008 20:26:04 MDT

Hi,
We want to access database from webserver i.e. on the login page. In the login page we will be having a survey form which the users fill. This data is to be updated to the database. But we can't deploy the war file in application server and access the war from the webserver since the application is protected i.e. it has access only for the logged in users.
Please send me reply on this ASAP. any reply is appreciated.
Any other alternatives to implement this is most welcomed.
