oracle.jbo.server.util
Class SafeExec

java.lang.Object
  extended by oracle.jbo.server.util.SafeExec

public class SafeExec
extends java.lang.Object

Executes a subprocess in a separate thread, and monitors the executing subprocess. The output can be captured and redirected to a stream. Also, the subprocess is given a finite amount of time to complete, and will be forcibly terminated if it doesn't complete within the timeout. This class is used by the BC4J test framework to deal with errant tests that don't terminate, but it is a standalone utility that can be used anywhere.

Since:
3.1
