Calling Session Bean from Repository Service

[Former Member]

Hello experts,

I have written a SessionBean with Home and Remote Interfaces that has a method UpdateKbUpdateInfo() which uses

CMP Entity beans to do the database transactions.

I call the UpdateKbUpdateInfo() method of the session bean like the following

public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)

{

out = new PrintWriter(response.getWriter());

try {

javax.naming.Context context = new javax.naming.InitialContext();

Object obj = context.lookup("applications/knet");

UserInfoHome userInfoHome = (UserInfoHome) javax.rmi.PortableRemoteObject.narrow(obj,UserInfoHome.class);

UserInfo userInfo = userInfoHome.create();

String msg = userInfo.UpdateKbUpdateInfo("1234","test","test",12345678);

out.println(" the message is : " + msg);

} catch (ClassCastException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (RemoteException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (NamingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (CreateException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

It works fine - no problem.

In the same par file I have created a repository service. The following is the defination of the service

public class ReportingService

extends AbstractRepositoryService

implements IReconfigurable, IResourceEventReceiver {

}

In the received() method of the service I use the follwing code to call the ejb. It is similar to the above code.

public void received(IEvent event) {

ResourceEvent resEvent = (ResourceEvent) event;

IResource aResource = resEvent.getResource();

String room_id = .......................

String resourceName = .....................

String eventtype = ................

long timestamp = .....................

try {

javax.naming.Context context = new javax.naming.InitialContext();

Object obj = context.lookup("applications/knet");

UserInfoHome userInfoHome = (UserInfoHome) javax.rmi.PortableRemoteObject.narrow(obj,UserInfoHome.class);

UserInfo userInfo = userInfoHome.create();

userInfo.UpdateKbUpdateInfo(roomid,resourceName,eventType,timestamp);

} catch (ClassCastException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (RemoteException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (NamingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (CreateException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

} else

log.LogAction(" Rerource null " ,Logger.LEVEL_ERROR);

}

catch (ResourceException re) {

log.LogAction("Exception in archieving --" + re.getMessage(),Logger.LEVEL_ERROR);

}

}

But I get the following error. Similar code works from Portal Component but does not work form a repository service.
