何为远程调试？我们一般调试一个 web项目的java代码时，需要将你的tomcat服务器和你的开发工具（比如Jbuilder）集成，或需要工具的一些插件支持(比如Eclipse 下的myclipse等)，这些方式都是在本地进行，即你的开发工具和tomcat运行在同一台服务器上，如果你的开发工具和服务器不再一台机器上那就需要实现远程调试功能了。

实现方法：
在tomcat的catalina.bat文件中加入下面的设置，当然SET CATALINA_OPTS 变量应该在使用它之前。这是在tomcat启动时设置一些虚拟机参数，使服务器允许远程连接功能，address=5888表示远程连接的端口号，可以设置成任意其他不冲突端口。其他的应用服务器比如weblogic也应该可以设置这些参数，有兴趣的可以测试。

SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5888
这样就Ok了，重启动tomcat,可以直接独立启动，而不用在eclipes的插件中启动。打开eclipse中的debug设置窗口，选择Remote Java Application ，新建一个debug项，输入服务器IP和刚才设置端口号，点ok就可以进入debug状态了。Jbuilder中同样可以设置Remote Java Application。

方法1：适用于tomcat6

修改startup.bat 在尾部修改成以下列方式启动

set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket
call "%EXECUTABLE%" jpda start

其它的java远程调试，在jvm上添加如下参数：
-Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=y

方法2：适用于tomcat5
修改catalina.bat

set _EXECJAVA=%_RUNJAVA%
set MAINCLASS=org.apache.catalina.startup.Bootstrap
set ACTION=start
set SECURITY_POLICY_FILE=
set DEBUG_OPTS=
set JPDA=
set JAVA_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=9999,suspend=n,server=y

(转)Tomcat启动脚本catalina.sh

http://bluestar.javaeye.com/blog/181464

关键字: tomcat 启动脚本

1 - 概述

脚本catalina.sh用于启动和关闭tomcat服务器，是最关键的脚本
另外的脚本startup.sh和shutdown.sh都是使用不同的参数调用了该脚本
该脚本的使用方法如下（引自该脚本本身）：

  echo "Usage: catalina.sh ( commands ... )"  echo "commands:"  echo "  debug             Start Catalina in a debugger"  echo "  debug -security   Debug Catalina with a security manager"  echo "  embedded          Start Catalina in embedded mode"  echo "  jpda start        Start Catalina under JPDA debugger"  echo "  run               Start Catalina in the current window"  echo "  run -security     Start in the current window with security manager"  echo "  start             Start Catalina in a separate window"  echo "  start -security   Start in a separate window with security manager"  echo "  stop              Stop Catalina"

Tomcat中设置远程调试设置

http://blog.chinaunix.net/u/21344/showart_498246.html

 在tomcat/bin/的catalina.bat文件中加入下面的设置，当然SET CATALINA_OPTS 变量应该在使用它之前。这是在tomcat启动时设置一些虚拟机参数，使服务器允许远程连接功能，address=5888表示远程连接的端口号，可以设置成任意其他不冲突端口。其他的应用服务器比如weblogic也应该可以设置这些参数，有兴趣的可以测试。

SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5888 

这样就Ok了，重启动tomcat,可以直接独立启动，而不用在eclipes的插件中启动。打开eclipse中的debug设置窗口，选择Remote Java Application ，新建一个debug项，输入服务器IP和刚才设置端口号，点ok就可以进入debug状态了。
不过要注意在Linux下，有一点点差异，是要编辑catalina.sh文件。      而且要改成这样：
     CATALINA_OPTS="-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5888"
     也就是把SET去掉，后面加双引号引起来，因为在Linux下，是没有SET这个语法的。
