The Tomcat server is the one that needs the libdrmaa to be in its  
LD_LIBRARY_PATH because it needs to launch the jobs via DRMAA. The  
client doesn't need this property to be set. Make sure that that this  
environment variable is set correctly before starting Tomcat (and also  
that this environment variable is available to Tomcat as well). I am  
assuming that you are starting up Tomcat from a bash shell - so an  
export LD_LIBRARY_PATH before running the Tomcat start script on the  
same shell should do the trick.

I assure you that this is not a problem. If you were running the  
service via SSL and had set up an authorization handler, the client's  
DN would be used to restrict access to the service. However, since you  
are running this service over regular HTTP, this information is simply  
logged, and no action taken. So there is no authentication issue for  
sure.

We are running some tests here to test out Opal with DRMAA+PBS - will  
let you know how that goes. Thanks for testing this feature out for us.

Cheers,
Sriram
