When I try to call an RPG stored procedure from my Java program it hangs. In debug, when I step from the execute...
statement, it appears that control leaves my program and never returns.
JDBC runs in process or out of process. The default is out of process so your call was sent to a JDBC thread that hasn't returned a result (example, if there is an object lock etc, on the iSeries). You can run the request in a Java thread easily and let your application continue while the background thread waits for the result. You can set a timeout that says the request failed and have the foreground thread invoke error handling, issue and error message, etc. if the background thread hasn't returned the result after X seconds.
