Cannot connect to instance of Tomcat 6 started in Eclipse

Question

I am running Tomcat 6.0.36. The server runs fine when run standalone in the console. I also configured Eclipse to be able to run it so that I can debug. The configuration went through successfully with no errors. However, when I ran the server, I was unable to access http://localhost:8080 in a browser (get a 404).

Here is the Eclipse trace:

The console trace is as follows:

The first thing I noticed is the 2nd line from the Eclipse trace:

INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path

while the well functioning console trace reports

INFO: Loaded APR based Apache Tomcat Native library 1.1.23 using APR version 1.4.6.

Is APR indeed the problem? If yes, how do I fix it so that the Eclipse server uses the same library as the console?

Answer 1

APR is not a problem. When you start tomcat from eclipse, eclipse 'overrides' some server configuration (also you can change config files directly from eclipse in the 'Server' project under package/project explorer).

If you want to access root of your tomcat you can double click on the server (when all projects are removed) and select the configuration that says Takes control of Tomcat installation . Then save, restart the server and you'll be able to access localhost without any app deployed on it.
