I am trying to invoke some java developed codes from Unix services. I have used BPXBATCH utility to achieve this but i get an error as "javaclass Helloworld" not found.the java developed codes was given to me was class.classpath. I was trying to invoke codes as "parm=sh java helloworld" and by coding the path=/jproj/proj2/class.classpath in jcl. Is there anyone who can help me in running the java developed codes in mainframes. From the java point i am not good but my objective is to run this codes in mainframes. Is there anyone who has worked in similar kind of projects.
