title: NoClassDefFoundError: org/apache/catalina/startup/Bootstrap when running tomcat from exe/as service
body: <p>I have been running a Tomcat 6.0.37 server for quite some time via the startup.bat.Now I want to run tomcat as a service that starts automatically when the machine starts up.</p>
  
  <p>I created the service with the bat : service.bat install.This created the service succesfully.When trying to start it however I get the error in the title.I then tried running just the exe(tomcat6.exe).This gave me the exact same error.</p>
  
  <p>I have checked that CATALINA_HOME,JAVA_HOME and JRE_HOME is set correctly.bootstrap.jar does exist in tomcat/bin.Path to the jvm is correct.jvm.dll does exist in jre6/bin/server.</p>
  
  <p>I also found a thread with a different class missing where they said rt.jar was missing from the jre,I checked this and mine exists in jre6/lib/.I really don't have anymore ideas as to what can be wrong.</p>
