call rpgle program from within a java program...

from within the IBM i.... specifically in the QSH command entry...
I have tried to copy and paste several examples and have not been
successful...

to clarify.. do I have to use a driver to connect back to the i?

import com.ibm.as400.access.AS400;
import com.ibm.as400.data.PcmlException;
import com.ibm.as400.data.ProgramCallDocument;

boolean rc = false;
AS400 as400;
ProgramCallDocument pcd;
String path = "/QSYS.LIB/GEMLIB.LIB/GETMQMSG.PGM";
as400 = new AS400 ();
pcd = new ProgramCallDocument (as400, "GETMQMSG");
pcd.setPath ("GETMQMSG", path);
pcd.setValue ("GETMQMSG.MESSAGE_1", message);
rc = pcd.callProgram("GETMQMSG");


I am getting the following errors:
Recv.java:39: error: unreported exception PcmlException; must be caught or
declared to be thrown
pcd = new ProgramCallDocument (as400, "GETMQMSG");
