Prerequisite: one of the following two
1, Linux configure tomcat in catalina.sh add the following
CATALINA_OPTS = "- Xdebug -Xrunjdwp: transport = dt_socket, address = 8000, server = y, suspend = n" ( do not wrap to the same line )
2, Window modified catalina, bat file, add:
Set “CATALINA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"或
SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8999
Parameter Description:
-Xdebug: Enable debug mode
-Xrunjdwp <sub-options>: load JVM 's JPDA reference implementation library
= the dt_socket Transport: the Socket connection, optionally dt_shmem connected to the server through the shared memory debug mode
address = 8000: debug server listens on port
server = y: if the server is, n- client
suspend = n: whether to start the process of loading pause, the y- is when you start to pause, to facilitate debugging boot process
3, modify the registry HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Apache Software Foundation \ Procrun 2.0 \ ivms6-Tomcat-6700 \ Parameters \ Java content option option to add the following information:
-Xdebug
-Xnoagent
-Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5889
4, start tomcat , to see tomcat Launch OK,
If you start successfully, Tomcat log file (catalina.out) there will be the following output:
Listening for transport dt_socket at address: 8000
5, using the eclipse debugging:
Click Debug , you can debug the
The rest is the same as the ordinary debugging. Breakpoints added directly in the source code on the line
2、Window中修改 catalina,bat文件，添加：
Set “CATALINA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"或
SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8999
参数说明：
-Xdebug ： 启用调试模式
-Xrunjdwp<sub-options> : 加载JVM的JPDA参考实现库
transport=dt_socket ：Socket连接，可选dt_shmem 通过共享内存的方式连接到调试服务器
address=8000 ：调试服务器监听的端口
server=y ： 是否是服务器端，n为客户端
suspend=n ： 启动过程是否加载暂停，y为启动时暂停，方便调试启动过程
3、修改注册表中HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\ivms6-Tomcat-6700\Parameters\Java内容option选项，添加如下信息：
-Xdebug
-Xnoagent
-Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5889
4、启动tomcat，看看tomcat是否启动成功，
如果启动成功，tomcat日志文件(catalina.out)中会有如下输出：
Listening for transport dt_socket at address: 8000
5、使用eclipse调试：
点击debug，就可进行调试了
剩下的就和普通调试一样了。断点直接在源代码中添加就行
