LinkageError when accessing to admin portal

[angelo.dangelo]

Hi,
I'm using JBoss Portal 2.6.1 in bundle with AS 4.2.1 and Oracle 10 db.
I deployed my ear application, which contains (besides the WARs of my portlets) the following libraries:
- commons-validator-1.3.0.jar
- jakarta-oro-2.0.8.jar
- joda-time-1.4.jar
- jsf-facelets.jar (ver 1.1.12)
- jsf-portlet.jar (ver 1.2.1)
- tomahawk-1.1.6.jar

After visited my portlets, If I try to access to admin portal, clicking Admin link in the dashboard nav, I have this error:

15:27:04,828 ERROR [CommandServlet] Exception in command invocation
java.lang.LinkageError: loader constraints violated when linking javax/faces/component/UIComponent class

...

Could you, please, help me to solve this problem?

Thank you.

Hi Angelo,

I have the same problem.
I found a work-around:
-Start Jboss without the custom ear application
-login as admin in jboss portal
-visit admin page
-deploy ear application

After it you can redeploy your application as many times you need.
However if you have to re-start jboss you have to repeat the previous steps. Remember to delete the temp folder too.

Please, let me know if you find a "better" solution.

Kind Regards
