I have java file which is running on Websphere Application Studio (WSAD). From the Java file i need to invoke a java file to run as like it runs on command prompt. So what i did is i got the RunTime instance and tried to execute the java file like

Runtime.getRunTime.exec("java -cp classpath JavaFilename);

the system was not showing any result or error. Please help me to get it resolved and run the java file

Try using an absolute path for "java", i.e. something like "/usr/bin/java". You may also have to use absolute file paths in the classpath.

You should also read this article; you may have to handle I/O as described in it.
