Mac上解决Tomcat远程调试冲突与配置指南

Eclipse Remote Debugging for Mac OS X
Added by Anthony Whyte, last edited by Anthony Whyte on Oct 27, 2005  (view change)
Assumptions
Mac OS environment
Java 1.4.2 installed
Tomcat 5.5.x installed together with Compat *.jar
Maven installed and build.properties defined
Eclipse 3.1.x installed
MyEclipse 4.0.x installed (optional)
Setup
1. Environment: set JPDA variables (e.g., saved in .bash_profile)
Set the Java Debug Wire Protocol (JDWP) for the connection and the port the debugger will use to communicate with the JVM, typically port 8000. Add lines, save and restart system.

# Eclipse Debugging
JPDA_TRANSPORT=dt_socket; export JPDA_TRANSPORT
JPDA_ADDRESS=8000; export JPDA_ADDRESS
However, I recently discovered that a certain application (unknown at present) is squatting on Port 8000 and preventing the debugger from launching. So I reset my JPDA address to Port 8001 and changed the port address in the Eclipse debugger and all is well again.

# Eclipse Debugging
JPDA_TRANSPORT=dt_socket; export JPDA_TRANSPORT
JPDA_ADDRESS=8001; export JPDA_ADDRESS
2. Tomcat: start in debug mode
arwhyte $ cd $CATALINA_HOME
tomcat $ catalina.sh jpda start
3. Eclipse: set breakpoint(s) in code and switch to Debug Perspective
Debug Perspective: Window > Open Perspective > Debug > Other > Debug

Click on Bug icon, click Debug... and launch debug configuration wizard. Select Remote Java Application, click New and define the following settings:
