Unable to start Apache Tomcat as a windows service

Hi All,

I am able to start Tomcat as a windows service and from today it stopped working. No changes in the environment.

I referred to this document (https://www-304.ibm.com/support/docview.wss?uid=swg21503767) and everything seems to be perfect.

Errors popped up in the stderr_<date>.log

java.lang.ClassNotFoundException: org.apache.catalina.startup.Catalina
at java.net.URLClassLoader.findClass(URLClassLoader.java:497)
at java.lang.ClassLoader.loadClass(ClassLoader.java:639)
at java.lang.ClassLoader.loadClass(ClassLoader.java:605)
at org.apache.catalina.startup.Bootstrap.init(Bootstrap.java:222)
at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:410)

Any pointers to my problem?

Thanks in advance.

Cheers,
Simon
