I'm trying to process enable an operation on the server by doing some thing like this in my service method

try {
if (teamAreas.length > 0) {

createOperation = new AdvisableOperation(OPERATION_ID_GETPLANS,
null, teamAreas) {

@Override
public IOperationReport run(
IBehaviorConfiguration configuration,
IProgressMonitor monitor)
throws TeamRepositoryException {
// TODO Auto-generated method stub
return null;
}

};

IServerProcess serverProcess = processServerService
.getServerProcess(teamAreas);

IOperationReport report = serverProcess
.adviseAndExecute(createOperation);
}
} catch (TeamRepositoryException e) {
System.out.println("inside exception");
System.out.println(e.getMessage());
}

Here is my related content in plugin.xml

<extension>
<category>
<operation>
<description>
The server-side view plans operation.

</operation>


</extension>


Now for every user who logs-in and tries to invoke the method, I get this output 'View Plans' failed. Missing required license.. Any Help?
