[jboss-dev] JBoss kills started process

During shutdown JBoss 4.2.1 stops (kills?) processes started by Runtime.getRuntime().exec(...) I've created a MBean to control other program needed to work while my aplication under JBoss is running. This process is started by Runtime.getRuntime().exec(...) in MBean.start() method. In MBean.stop() I'd like to send some message to this process - but it is already dead. Q1: why JBoss stops process started by Runtime.getRuntime().exec(...). This not conforms to Java specification. Normal Java program doesn't stop process started by Runtime.getRuntime().exec(...). Q2: how I can change this behaviour of JBoss (I found nothing in documentation)? Kind regards, Krzysztof Tomaszewski
