Can Anyone let me know about how to create a Java Program (.classfile) that would be running on a windows or Linux machines Machineand makes a internet web service call every 3 hours.
no, but you can run java programs with javaw, which helps a little if you want abackground app.on linux machines, you just run the java program with '&' at the end of thecommand line to demonise the pogram.
In Linux you can use "cron" with java and you don'thave to forget CLASSPATH.
