Problem: Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

Solution:

Remove the possible Breakpoint that presents conflicts
Open the "Debug View" /  Tab "Breakpoints", search them and uncheck them

Other possible solution: Change Start time in Server

Open the "Servers View" / Open Tomcat (or other) / "Tab Timeout" / Change Start tim
