Hello!
I would be grateful for any advice with the below problem I am
encountering with the WicketSessionFilter.
I managed to convince my colleagues to migrate our www.mypharmisis.com
(a drug ordering system for the Pharmaceutical industry) from Struts
to Wicket after the success of a greenfield project using Wicket. I
don't have the resources to migrate all at once so Struts 1 and Wicket
so I have set them up to coexist congruently. However! I am having
problems sharing necessary state between Struts 1 and Wicket using the
WicketSessionFilter :-(
When my Strut controllers tries to access my WebSession, it throws a
java.lang.IllegalStateException: you can only locate or create
sessions in the context of a request cycle. My stack trace is:
org.apache.wicket.Session.findOrCreate(Session.java:206)
org.apache.wicket.Session.get(Session.java:250)
com.mypharmsisis.pages.session.PharmisisSession.get(PharmisisSession.java:24)
com.mypharmisis.struts.isis.actions.AbstractEasyAction.displayPage(AbstractEasyAction.java:52)
com.mypharmisis.struts.isis.actions.EasyOrderHomeAction.displayPage(EasyOrderHomeAction.java:53)
Here is a snippet of my web.xml:
