However, we don't have installed the SAS StoredProcessApplication (I have to ask to the admins to be sure if they don't have it, but I'm quite fond about it), so I don't know where I could locate the missing jar: sas.svc.bootstrap.jar.
I don't know whether you can get or find the JAR files without installing the Middle Tier of the BI platform or the Java "plumbing" that's part of the Middle Tier.
Your best bet for help with this question may be to contact SAS Technical Support. They can give you pointers about where to look for things and test things to see if you have a correct install and correct configurations.
And, they can help you with your servlet question.
thanks for your kind answer! I've been able to solve this problem with some other Java code (it seems that the ServerFacade is an useful class for connecting to the metadata repository, but nothing more ).
Now I've got another kind of problem, but I'm going to open a new topic...anyway, thanks again!
