groovy & context

Hi, I try to save a Java- object to the context with groovy: <% test=context.getContext().get("test"); if(test==null) println "test is null" else println "test is not null" context.getContext().put("test",new Object()); %> If you reload the page the object should be in the context and the output should be "test is not null". But unfortunately I get "test is null". I also tried it with the Servlet-Context like this: <% scontext=context.getRequest().getSession().getServletContext(); test=scontext.get("test"); if(test==null) println "test is null" else println "test is not null" scontext.put("test",new Object()) %> Then I get an exception: java.lang.NoClassDefFoundError: org/apache/catalina/session/StandardSessionFacade This class is in the catalina.jar which is located in tomcat/server/lib and the documentation of tomcat says: These classes and resources are TOTALLY invisible to web applications. I copied catalina.jar to WEB-INF/lib but then I get a ClassCastException: java.lang.ClassCastException: org.apache.catalina.session.StandardSessionFacade I guess this is because of different ClassLoaders. How can I save a Java-Object to a session?
