Run into a problem that Apache TomCat has stopped working. After doing some research discoveed that TomCat does not automatically start on boot up. I did go to TomCat configuration and clicked on the START button but nothing happens. Looking around find a log file and noticed the following error:

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

It may be the issue with the Java not referenced properly in tomcat. Try to run the Tomcat in Command Line by going to the folder where you installed your tomcat directory.

ex: C:\ProgramFiles\Apache Software Foundation\Tomcat 5.0\bin\startup.bat

2. To start the Tomcat automatically when you login to your machine. Goto Control Panel --> Administrative Tools --> Services --> Apache Tomcat and right click select the option Automatic it might set as manual now.

Hope it helps,

Jeff,

You did not mention when you noticed Tomcat wasn't working anymore. Was this after upgrade, or initial install, or did it just happen out of the blue (which of course never happens, because something must have changed, only you did not notice it)?
It may be that the java version you're using is not 100% compatible with the tomcat version, or not all paths to java (and/or java parts) have been set up correctly, or ....

After removing and reinstalling Apache Tomcat without any success I downloaded and reinstalled Java Version 6, Update 12 and Apache Tomcat is now working correctly.

Frustrating at times but a good learning experience!
