Breakpoints ignored in Eclipse?

[Kravchenko Dmitry，修改在13 年前。]

How to debug liferay portlets in Eclipse? I have breakpoints totally ignored, while server is working, "Debugging" flag is indicated and protlet is started with "Debug As..." command.

What can prevent debugger work?

Check that your project is in the Source tab in Debug Configurations. If it's not then the breakpoints are ignored.

Additionally, if you aren't running the Tomcat server from within Eclipse, make sure that your Tomcat instance is configured for debugging and your Eclipse is configured to hook into it, as described on the Tomcat Wiki.

Thank you, it started to work!

It is stange although: why it was so? While adding your option, I saw that there was "Default" entry in "Sources" tab, which, in turn, was containing some names of my project. Why wasn't it work w/o explicit setup?

Directly speaking: why Eclipse does not execute a direct order of "debug on server" which it is given? What is the sense of "debug" command if the source doesn't set in the tab?
