From Java 6 a process needn't have the management agent enabled when it starts, as the Attach API permits the management agent to be activated on demand.
Common Troubleshooting Scenario
If you have already looked into Tomcat logs, there are no error messages, and you just want to find out what is going on, you may try the following
- Look into Tomcat access log (the log file generated by AccessLogValve).
- If your request is not listed there, then it has not been processed by Tomcat. You need to look elsewhere (e.g. at your firewall).
2. Take a thread dump. This way you will find out what Tomcat is actually doing. - If you are troubleshooting some process that takes noticeable time, take several (three) thread dumps with some interval between them. This way you will see if there are any changes, any progress.
3. Try debugging. - A good place for a breakpoint is
org.apache.catalina.connector.CoyoteAdapter.service()method. That is the entry point from Tomcat connectors and into the Servlet engine. At that place your request have already been received and its processing starts.
- If your request is not listed there, then it has not been processed by Tomcat. You need to look elsewhere (e.g. at your firewall).
