I'm trying to run a Java program (Poseidon) under Windows XP (SP1 -- not SP1a as far as I can tell). I have msjava.dll in my system directory and many java classes elsewhere on my drive -- but I don't have java.exe or the equivalent.
What do I need to do to be able to run the program?
I don't want to remove the java-related files and start again with Sun's implementation of Java. I just want to tweak the MS Java implementation.
