Hi Henner Thank you for the reply.
I use the current binary (2.5) with Tomcat 5.5.9, the only non-default configuration to this Tomcat is that I have also unzipped the compat 5.5.9 libraries to get JDK 1.4.2 support, and that I have done the log config according to http://jakarta.apache.org/tomcat/tomcat-5.5-doc/logging.html Any web application using log4j deploys to Tomcat without problem - except web applications based on DBForms, which breaks Tomcat logging. Also I discovered last night that any other web application using log4j stops working after after a DBForms web application has been deployed. I have reproduced teh issue on multiple Tomcat installations, both on WIndows and Linux. When time permits, I'll grab the org.dbforms.servlets.ConfigServlet source and see if I can disable the log4j loading in there, compile and see if that was the root cause or not. I will keep you updated with my findings. best regards Audun On 7/6/05, Henner Kollmann <[EMAIL PROTECTED]> wrote: > Do you use the current sources?
