I have follow all the instruccion to installate PAT in a Pentaho (http://code.google.com/p/pentahoanal...onPluginForPAT) but when I try to launch the example, it doesn't work.

Software:
- biserver-ce-TRUNK-SNAPSHOT-hudson-BISERVER-CE-2466.zip
- PAT-0.5.0-SNAPSHOT.war
- last version plugin-pat

Code:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.ClassCastException: $Proxy15
    org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:583)

...
Any idea?
