Can I execute two java programs of different versions of java at the same time?

[samuel, liu]

I am working on a project that only works under Java1.2. And now I need to impalement a screen capture tool for this program. However, I need to use Robot Class in Java 1.3 for the screen capture tool. My question is that can I execute two java programs of different versions of java platforms at the same time? If I can do that, can you explain to me that how can I do it? Or point out some articles or documentations, which might be useful for solving that problem?

What functionality of java1.2 are you using that isn't available in 1.3 (third party packages?)? I think the cleanest solution would be to port the 1.2 code to 1.3. Just a thought.

I need to use Robot Class in Java1.3, which is not in java1.2. well, i wish i can make the decision to port the whole project from 1.2 to 1.3, but i can't.

Just install both versions of the JVM on your machine. Then, call the java.exe using an explicit path. For example:

c:\jdk1.2\bin\java.exe prog1

c:\jdk1.3\bin\java.exe prog2

One other solution could be use an IDE for one project. Tell the IDE to use a particular version of Java(1.3 the newer one) and then keep using the old way to compile/run your older program -- which will still use the old one 1.2
