    Jnlp .jar download


      I am making a java web start application. I have so many jar files, which are being used by that application...I am adding the jar files like this:

      <jar href="lib/appframework-1.0.3.jar"/>
      <jar href="lib/swing-worker-1.1.jar"/>

      Actually When I try to run the application offline, it works fine. But when I try to run the application online, it gets very slow...it takes time to download jar files(I think so).....and it takes five minutes to execute a functionality by the application. I don't know how can I fix this. The size of some of the jar files in the resources are big...

      Please let me know the solution of this problem!

      Thank you.

          If you don't already have try adding <update check="background"/> to see if it would help.
          Also, usually you would have your supporting jars defined with download="lazy" to help your app startup time.

            Please post full JNLP file here.
            How big is "big" here?

            Do you have <update check="background"> in your JNLP file?

            Debug hints:
            * Enable java console, enable verbose tracing (http://download.oracle.com/javase/7/docs/webnotes/tsg/TSG-Desktop/html/plugin.html#gcexdf)
            and see what is going on when application takes longer than you expect

            * Use http sniffer tools to trace network connections on startup (e.g. wireshark). Your goal is to have 0 network connections when application is cached.
