I am sending a message to a Queue. One MDB there listens to this queue when message arrives . In the OnMessage method , I am running some command ( a batch file) My code in onmessage look like java.lang.Runtime runTime = Runtime.getRuntime(); java.lang.Process process = runTime.exec(Command2); process.waitFor(); This process may take long time( and block the thread) . Is there is any way I can cancel this task after message that initiates this gets into the queue. How can I cancel this process ? Any Idea ??    More>>


I am sending a message to a Queue. One MDB there listens to this queue when message arrives .

In the OnMessage method , I am running some command ( a batch file)

My code in onmessage look like

java.lang.Runtime runTime = Runtime.getRuntime();

java.lang.Process process = runTime.exec(Command2);

process.waitFor();


This process may take long time( and block the thread) .


Is there is any way I can cancel this task after message
that initiates this gets into the queue.

Too easy.
Make a thread inside your thread, which will look to see if the process is null or not, and sleep for a second.
If the process is not null, then sleep for how long u want to wait for that process, then destroy it (with process.destroy()) no matter what.

I wanted to send u the code, too, but while u probably make 10 times more money than me, I think it's enough.

Best regards, tibi.
