Report Designer java.util.collection

[klawi]

Hi there and greetings,

maybe someone out there can help me. I have a tabel within my database with several entries.
Now, I want to run a report with a parameter to select one or more choices from this table.
At the moment I use java.util.collection as a class and I can choose any number of Input parameters
by typing them in the value box. This works just fine!

But the possible choices for the input parametrs should be selected from the database table! Is this possible?

Thanks for yout time and best wishes
Werner
