can't deploy spring project on tomcat

Question

I had a working spring project and updated the framework to version 3.2.2. Now I can build my project but I can't deploy it any more. Aparently Tomcat can't find a class responsible for the logging. But the springframework is in my CLASSPATH, and I'm sure it is contained in the WAR, too. Did I misunderstand the tomcat log?

I even started a new minimalistic spring project - same result.

I'm quite stuck here - any help is appreciated.

Here's my Netbeans log:

Tomcat server started.
Incrementally deploying http://localhost:8080/SpringTest
Completed incremental distribution of http://localhost:8080/SpringTest
Incrementally redeploying http://localhost:8080/SpringTest
Deploy is in progress...
deploy?config=file%3A%2Ftmp%2Fcontext9144781847406895845.xml&path=/SpringTest
FAIL - Deployed application at context path /SpringTest but context failed to start
/home/maex/NetBeansProjects/SpringTest/nbproject/build-impl.xml:1061: The module has  not been deployed.
See the server log for details.
BUILD FAILED (total time: 7 seconds)

And the more interesting Tomcat Apache log:

Answer 1

It looks like you have several issues, but let's start with the 2 obvious ones.

INFO: validateJarFile(/home/maex/NetBeansProjects/Bonjour/build/web/WEB-INF/lib/servlet-api.jar) - jar not loaded...

This error is cause by the inclusion of the servlet*.jar in your runtime, it only needs to be available during build time. The servlet container (e.g. tomcat) should provide the servlet*.jar for you at runtime.

Caused by: java.lang.NoClassDefFoundError: Lorg/apache/commons/logging/Log;

You are probably missing the commons logging jar. make it available, either in the webapp/WEB-INF/lib or container lib.
