there are about one trillion technologies to share data between two java applications, most popular are probably RMI and CORBA.
In your case I would call the second application via CORBA and register a user obtaining an unique code, than inlude this code into the link to the second webapp which the browser sees. The second webapp can than test this code and react accordingly. This way both apps can be deployed on same machine or different machines or even different parts of the world and it will still work. If you dont have much data to send to the other application (only userid for example) you could encrypt this data with an encryption algorithm (blowfish?) and decrypt it on the other side. regards Leon On 6/22/06, Miller, Andy <[EMAIL PROTECTED]> wrote:
I've found need to do this myself before. It ended up being a big mess. Fortunately for me I only had a few pieces of data that needed sharing back and forth, so I simply used Cookies to save myself a ton of time. However, it is not a graceful solution, and as eric has stated, it is a shortcoming...

You'll be forced to do something kludgy and authenticate to both systems and maintain two sessions. I would love to see a thread started about this because it is a big shortcoming I come up against frequently in Java. That is, different wars and contexts are a great way to separate and manage different large scale projects, but when it comes time to piece it back together as part of a large possibly modular application, yr fcked. Siteminder (a proprietary product) is a way to get around this and is Java friendly, but don't know how it works.
