Re: find out why the loading of the driver fails
Thanks for your suggestions. Amazingly enough it seem to work if I put the driver where you suggested. I got another error, but that seem to be Postgresql-related. I suppose the reason why it is not loaded from the WEB-INF/lib-directory is because the driver is defined in server.xml as a resource, and that the container and webapp is somehow seperated. And I might have screwed up the CLASSPATH when starting tomcat, so it can't find the driver frm there either. back to the drawingboard. thanks. //ju --- p niemandt wrote: 1.

find out why the loading of the driver fails
Hello. Does anyone have any good hints on how to tweak tomcat to output more information about errors? When I am trying to load a JDBC-driver it fails, but it doesn't give me a clue on why it fails. I checked the web for similar errors, so I started by adding the .JAR-file to the classpath, and put a copy of it in WEB-INF/lib. I also doublechecked that the dbengine is up and running, and that the user/password/ip is OK. Finally I set the debug-attribute in the Server-tag to 1, but it didn't give me any more information. :-/ The error I got is: --- org.apache.jasper.JasperException: SQLException: Cannot load JDBC driver class 'org.postgresql.Driver' at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:248) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) ... --- Any ideas are welcome. TIA // ju _ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
