【转】Tomcat中设置远程debug方法

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.iteye.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"

#!/bin/sh
# =============================================================
# 该脚本设置正确的环境变量和系统信息，然后启动或者停止tomcat server
# 具体的操作是：
# 使用命令行参数作为args的实参，调用org.apache.catalina.startup.Bootstrap.main(String[])
# ==============================================================

#                   "stop", or "run" command is executed.
#
#   CATALINA_TMPDIR (Optional) Directory path location of temporary directory

#
#   JSSE_HOME       (Optional) May point at your Java Secure Sockets Extension
#                   (JSSE) installation, whose JAR files will be added to the
#                   system class path used to start Tomcat.

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。
