java -jar doesn't use the environment classpath setting. You need to specify the classpath in the jar's manifest file.

actually iam installing the application using install4j tool.when i run the jar command the application should run.i cannot hardcode the classpath setting
because it may run on my system but on other system the classpath will be different.

So install the required jar files in the same directory as InstaSecure.jar and use relative paths names in your classpath.

But problem is the required jar files are different for different software version which the user may be selecting.

Well your install program will have to sort that out. All I'm saying is, if you want to use the -jar option of java then you have to specify your classpath in the manifest file. If this is a problem then don't use the -jar option.
 
It is sorta covered in the JavaRanch Style Guide.
