Problems with Swedish Characters

Hello!

I think this is a classic problem but I ca not see how to solve this.

I read info from a database that I think (99% sure) store data in UTF-8.

This data is filled into a XML Document with encoding UTF-8

This xml is sent over JMS to an other system.

But when it reach the other system the swedish characters is corrupted in the xml.

I guess when my Java app populates the xml the data is considered to be "Unicode" thare fore it gets corrupted. Correct me if I'm wrong. Do you think the same or do you have an other opinion?

And the most important how do I solve this?

Best regards
Fredrik
