I'm getting a strange exception when I try to execute a page-action:

This is the pageAction:
| <page view-id="/protected/examResults.xhtml"
| action="#{resultsManager.selectResults(examId)}">
| <param name="examId" />
| </page>
|
And this is the interface:
| public interface ResultsManager {
| public void selectResults(String examId);
| }
|
with a StatelessSessionBean named "resultsManager" implementing it.
This works fine on a windows-box where I develop, however it fails with the
above exception on a linux-box where I deploy it. Anyone knows why this should
not work?
I even tried to go back to a request-parameter and calling the method without a
parameter, but this gives the same exception on linux (and works fine on the
windows-box) - is it maybe something about the expression-language
extensions??!? I'm currently cluelless and any hints are highly appreciated!!!
cheers
