Could not use Derby plugin on Eclipse

Question

I have downloaded the latest stable version of Derby:

http://db.apache.org/derby/releases/release-10.8.2.2.cgi

Installed it to the Eclipse plugins folder, as suggested.

Then I am trying to use the following instruction:

http://db.apache.org/derby/integrate/plugin_help/start_toc.html

The third step fails:

Error: Could not find or load main class org.apache.derby.drda.NetworkServerControl

Googled, but cannot find the info how to solve this problem. Any ideas?

Answer 1

I have solved this problem by making a new clean project instead of using an existing project!
