Thanks to Hans-Peter Minnig i found out that my problem was the
version of the Jasper plug-in.
I used the version that i downloaded from the link i received from Servoy after the purchase.
I now use the version that i got from Hans-Peter and this works fine !!
Is there a way to check the version of the plug-in and is there a
way to check for available new-versions and upgrade ?
