You'll need to find an MD5 implementation in JavaScript and use it according to its directions.

Are you sure this is something you want to do on the client? This is something usually done on the server.

the jsp is executed on the server while the js code is executed by the browser on the client, so you can't store it.
You can always run a method on the server:



For javascript you'll have to modify the link that goes on the server. If you have



Now when you will click the second link you will modify the first one (it contains a parameter named "md5" with the desired value).
Anyone can see your js function code, so be careful.
I don't know what you really want but i hope this example will help you.
