[jboss-user] [EJB 3.0] - @EJB injection in JSP and JSP change

[xmedeko]

Hi, I have in my JSP


  | <!%
  |   @EJB
  |   Library lib;
  | %>
  | 

It works fine when I deploy/redeploy the application. But when I just change the JSP page and reload it in the browser, I got the exception


  | java.lang.IllegalArgumentException: failed to set value Proxy to jboss.j2ee:ear=books-ear.ear,jar=books-ejb.jar,name=LibraryBean,service=EJB3 implementing [interface cz.root.jboss.library.Library] on field cz.root.jboss.library.Library org.apache.jsp.search_jsp.lib; Reason: ClassLoaders of value and target are not equal

  | 	org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
  | 
  | 

My application EAR with EJB JAR and WAR:

  | books-ear
  |    +-- books-ejb.jar
  |    +-- books-war.war
  |    +-- META-INF
  | 

JSP pages are in books-war.war and all EJBs with interfaces are in books-ejb.jar. The WAR has no Java class or any JAR.

Do I miss something, e.g. do I have to set classloader?

Thanks
Andy
