Sounds like you are try to launch with the -jar argument but the JAR file doesn't have a Main-Class attribute in the manifest. If so then put the JAR file on your class path and specify the name of the main class, eg: something like: java -classpath foo.jar foo.Bar
Try this
java -XbootClasspath/a -jar <<Prog name>>
I think you are trying in windows XP.
Also you need to modify if there are any other jars to be reference. For eg if a.jar is also required for this try as below
java -XbootClasspath/a:a.jar -jar <<Prog name>>
