Enterprise Manager

Hi,
I get the following error when I go to my Enterprise Manager.

500 Internal Server Error
java.lang.NoClassDefFoundError: oracle/sysman/eml/app/Console at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpApplication.loadServlet(HttpApplication.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpApplication.findServlet(HttpApplication.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpApplication.getRequestDispatcher(HttpApplication.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpRequestHandler.run(HttpRequestHandler.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpRequestHandler.run(HttpRequestHandler.java(Compiled Code)) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java(Compiled Code)) at java.lang.Thread.run(Thread.java:568)


It doesnt even ask me for the login/password. The error comes as soon as I open Enterprise Manager.

Can somebody please advise me on this. It was working fine before. But then we installed a Grid Agent and we also set the x-server and naming service permanently into the reports server. So I dont know if this has something to do with it.

I will appreciate your replies on this.

Thanks in advance.
