I have created Java Programme which is based on Swing-Servlet Communication. After it the Jar-File which contain the Swing Programme Class files put on Client Side .same swing-Files on Server side .Now the Problem comes when i update any of Swing Files on server side then how could i download it to client. and second if i got download then how could i update my JAR files through this new File. with in Programme.
Actually there is nothing you should do. Just update your jar files on the server side. The JWS on the client will check for the latest updates and update the jar files to your classpath authomatically.
