i've written code for an applet which can be accessible by the remote browser.. before it starts
accessing features, browser has to load the jar file, right? i've 3 jar files all are of MB sizes
and due to this.. whenever a client opens application its taking big times to open starting page..
how can i overcome this problem?? is there a way for a client to work without jar in an efficient
manner??
bye,regards

1. You can install the jar files at client side and remove them from your html page.
2. You can extract all the class files from your jar files and and put them to the codebase of your applet, so that the browser will load the classes only when it need them. If the browse DOES need a lot of class files, this way is not efficient.

Alternative Ideas: if it is possible and you have the resources, lighten the applet by taking all the processing out and write it into a servlet.  Then set-up the servlet and applet to talk to each other.  Then your applet is basically just a gui (can include some pre-checking) and your servlet does the processing.  Distributed computing example.  However, it does make it more complex.  Or you could look into Java Web Start.  I tend to think of applets as 'small, cute thingies'  and anything that goes into the megabyte range as a qualifier for an application.

Mb sizes .... !!!

Good god, it would take years to develop so big an applet

It sounds like your jar files include stuff not needed

YOu do not need to send the client the whole Virtual Machine, you assume that the browser on the cleint has the standard classes and just supply your custom ..

I consider a jar file of 300K as massive and representing at least a years programming
