Java PHP Session Integration?

[nadreg]

I want to build a Java portal around a vBulletin installation I have, and I want to use a single sign-in across both platforms. Ideally, a user would sign-in to the vBulletin platform, but the Java side would have access to the user session.

Has anyone done anything like this before? Any ideas on how/if this can be done?
