Error when starting example code in JPVM

I am trying to run the example code provided with the JPVM,the java version of PVM.
I am able to start the JPVM daemon without any errors but when I try to run the example provided I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: jpvm/jpvmException
Caused by: java.lang.ClassNotFoundException: jpvm.jpvmException
    at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

Could not find the main class: hello. Program will exit.
Solution

  • I was running the examples from the examples directory, I copied the .class files into the JPVM root directory and ran them from there and it worked. apparently the jPVM root directory is the working directory and examples need to be ran from there.
