JavaBean with SESSION scope serialization-deserialization in tomcat issues: java.lang.IllegalStateException: Attempted to invoke a Seam component outside an initialized application

zmicer Feb 4, 2009 9:44 AM

Hi, All!

I have the following issue with seam. I would appreciate if someone point me to the roots of problem. I am rather novice in seam - thus it may appear this is not a problem but lacks of my understanding of concepts of seam. Then - in advance - sorry for silly question.

I have the following JavaBean:

@Name("searchResultsCash")
@Scope(ScopeType.SESSION)
@AutoCreate
public class SearchResultsCache implements Serializable {

And when I make restart of my tomcat server - I have the following exception

04.02.2009 10:29:46 org.apache.catalina.session.StandardSession activate
SEVERE: Session attribute event listener threw exception
java.lang.IllegalStateException: Attempted to invoke a Seam component outside an initialized application

It is seen the following
search.action.SearchResultsCache$$javassist1.sessionDidActivate(SearchResultsCache$$javassist1.java)

So in the case this is session bean - it has built in through javassist session listeners - which gets event form tomcat servlet container.

But the issue - is it Seam issue or something special should be configured.

I use tomcat 6.0 and seam 2.1.0.GA

Thanks in advance for reading and answering on that item.

Looks very much like the problem described here:

https://issues.apache.org/bugzilla/show_bug.cgi?id=42934

So upgrading to the latest Tomcat 6 version should help.

Thomas, thanks for this tip. I think this issue of tomcat relates to the trace I have provided.

I have tried to debug SeamListener and could see that exception appeared before calling of

   public void contextInitialized(ServletContextEvent event)    {       log.info( "Welcome to Seam " + Seam.getVersion() );       ServletLifecycle.beginApplication( event.getServletContext() );       new Initialization( event.getServletContext() ).create().init();    }

So that means sessionDidActivate is called before - somewhere at tomcat bootstrapping

The most interesting thing is I use tomcat 6.0.18 - one release after the version to where fix mentioned in the link you have provided should have been committed.

Hopely this exception doesn't ruins application - still it is unpleasant to see in log file.
