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

1. I would put the db driver jar under $TOMCAT/common/lib
This directory is shared by all your web applications: any libraries
under this directory should be visible to your app.
2. Set your debug to 100: There are a few places you can / should do
this (for developing / debugging): Basically, any place you see a debug
parameter / attribute: Make it 100: You should get a lot of debugging
information, including which jar files have been picked up and deployed.
