Can't setValue to PortletPreferences in JBOSS_2.4.0

[trungquoc2080]

I'm using Jboss version 2.4.0 to host portlets but I can't setValue to PortletPrefernces. Once more thing, the methods below runs well in JetSpeed_2.0 and WebSphere, but it throws exception in Jboss_2.4.0. Please see the codes below:

private void processSubmitEditLearningProgramAction(ActionRequest request){
PortletPreferences portletPref = request.getPreferences();

String loginUsername = request.getParameter(Constant.LOGIN_USERNAME);
String loginPassword = request.getParameter(Constant.LOGIN_PASSWORD);
System.out.println("+++++ spURL:"+spURL);
try {
portletPref.setValue(Constant.LOGIN_USERNAME, loginUsername);
portletPref.setValue(Constant.LOGIN_PASSWORD, loginPassword);

portletPref.store(); } catch (Exception ex) {
System.out.println("Error at function processSubmitEditLearningProgramAction store when submit....");
ex.printStackTrace();
}
}

When call this method, it throws an error:
10:18:58,879 INFO [STDOUT] +++++ loginUsername:admin
10:18:58,879 INFO [STDOUT] Error at function processSubmitEditLearningProgramAction store when submit....

If you know how to solve this problem, please help me. Thanks.

Are you logged into the portal when setting the preferences? 2.4.0 lets you go into edit mode when you are not logged in and then throws a read-only exception when you try to update the preferences. This has been fixed in 2.4.1, which doesn't let you get into edit mode unless you are logged in.

Hi Peter,
Thanks for your help, I will try to get Jboss 2.4.1 and test again. Hope that this problem will be solved.

Thanks,

I noticed one more thing. From where are you calling the processSubmitEditLearningProgramAction method? I hope you are calling it from the processAction method.

[trungquoc2080]

Hi Peter,
- This method is called when processAction().
public void processAction(ActionRequest request, ActionResponse response){
processSubmitEditLearningProgramAction(request);
}

- From link: http://labs.jboss.com/portal/jbossportal/download, I download Jboss 2.4.1 (Package: JBoss Portal Binary - Version: 2.4.1-SP1) and test the methods above but it is not working, it throws the same errors that I show to you. If you know another link to download Jboss 2.4.1, please give it to me, I will try to test more.
- Hope that you will read and reply mail to me soon.

Thanks,
TrungQuoc.

The only other thing I can think is to make sure the preference you are trying to set is defined in the portal.xml file and that it is not marked read only.
