Servlet + JSDT registry

hi,

Well, this is quite a specific question and i’m totaly unexperienced with servlets. I was wondering if it was possible to launch a registry with a servlet. More precisely, a registry from the Java Shared Data Toolkit api which is not a standart part of J2EE.
Therefore, 2 questions:
Is this running registry thing possible? (And create sessions afterwards?)

i’ve tried to set up a JSDT registry but i only get error after error.
Let’s look at this piece of code (nearly all the code! :P):


    ...
    if (RegistryFactory.registryExists("html") == false)
        RegistryFactory.startRegistry("html");
    ...

I’ve tried to put it into 3 different places:
in the constructor:
=> the “HTTP 500: internal server error.” page or a ‘NoClassDefFoundError’
in the init(…) method:
=> Can’t contact servlet runner at 127.0.0.1:6905
in the doGet(…) method
=> again the “HTTP 500: internal server error.” page or a ‘NoClassDefFoundError’

In some cases, i also had some 'ServletException’s, but i’m not sure in which case exactly they were.

Any idea why these 2 lines are making so much trouble? Is there a way to make these 2 lines work cleanly? Is it even possible to launch a registry via servlets?!

Does anyone know how this works?!?

…well, the reason was i was in a “server sandbox” which denied access to sockets or something like that, that’s all.
