Hi, I'm experiencing strange effects which indicate that there is something wrong with the thread safety of orion database operations. I have a swing UI that accesses a servlet which accesses lots of ejbs. after a few clicks, I get lots of database exceptions related to protocol errors. this happens randomly (e.g. first few times a finder method is invoked, it works fine, later it crashes with database exceptions, the again it works). I've only seen those kinds of protocol errors when I accidently accessed the same jdbc (Oracle) connection from multiple threads concurrently. I'm using orion 0.8.3 with Oracle 8.0.5 on linux jdk1.2.2 (problem happens with both the sun/inprise and the blackdown jdk) robert -- (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de
