Description Jim Anderson CLA 2020-10-01 11:22:05 EDT
I recently installed Eclipse IDE 2020-09 and I am trying to set up Eclipse to used Tomcat 8.0. I have created a project for a website that I am working on. When I try to run the project, I do the following:

1) I select the project in the naviator
2) I right click and select "Debug As --> Debug On Server

A "Debug On Server" window pops up

3) I click the arrow to the left of "Apache" and a list of possible Tomcat servers appears.
4) I select "Tomcat v8.0 Server"
5) I click on the "Next" button

The "Debug On Server window refreshes and has a sub-heading: "Tomcat Server Specify the installation directory". The 'Name' box correctly shows "Apache Tomcat v8.0". The box for "Tomcat installation directory" is empty with a 'Browse' button next to it.

6) I click on 'Browse..." button and an error window pops up with the following
message:

    Problem Occured
    Unhandled event loop exception
    No more handles

This is a serious error for me because I can not move forward at this point. I'm am going to try starting over by removing the installation and reinstalling Eclipse and the project.

As a side note, when I detect exceptions in my own code, I try to provide the source file name and the method name to help isolate where the error message comes from.

That is a operating system message and normally indicates a memory leak.

That's a great tip ;) Please take a look in your workspace directory. There is .metadata directory which contains a .log file. The information you mention should be in there. Please attach that.
