Setting up JPDA for Tomcat7 in ubuntu-server
提问by Ospho
I am attempting to setup the JPDA for Tomcat7 in ubuntu.
I have used the apt-get method of installing Tomcat7.
By attempting to edit the /usr/share/tomcat7/startup.sh file with the following lines I try to get tomcat7 to boot into debug mode and allow remote debugging via eclipse.
我正在尝试在 ubuntu 中为 Tomcat7 设置 JPDA。
我已经使用了安装Tomcat7的apt-get方法。
通过尝试使用以下几行编辑 /usr/share/tomcat7/startup.sh 文件，我尝试让 tomcat7 启动到调试模式并允许通过 eclipse 进行远程调试。
JPDA_TRANSPORT="dt_socket"
JPDA_ADDRESS="8000"
exec "$PRGDIR"/"$EXECUTABLE" jpda start "$@"
After editing the startup.sh file, I reboot tomcat7 using:
编辑 startup.sh 文件后，我使用以下命令重新启动 tomcat7：
sudo service tomcat7 restart
Then attempt to connect to the tomcat jpda in eclipse with the IP address and port 8000. I receive a "Connection Refused" error from Eclipse.
然后尝试使用 IP 地址和端口 8000 连接到 eclipse 中的 tomcat jpda。我收到来自 Eclipse 的“连接被拒绝”错误。
I have attempted to manually start tomcat7 using the startup.sh script rather than the service executable method as I thought perhaps the startup.sh was not being called.
我尝试使用 startup.sh 脚本而不是服务可执行方法手动启动 tomcat7，因为我认为可能没有调用 startup.sh。
sudo ./startup.sh
This failed with the following output:
这失败了，输出如下：
Using CATALINA_BASE: /usr/share/tomcat7
Using CATALINA_HOME: /usr/share/tomcat7
Using CATALINA_TMPDIR: /usr/share/tomcat7/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/share/tomcat7/bin/bootstrap.jar:/usr/share/tomcat7/bin/tomcat-juli.jar
touch: cannot touch `/usr/share/tomcat7/logs/catalina.out': No such file or directory
./catalina.sh: 389: ./catalina.sh: cannot create /usr/share/tomcat7/logs/catalina.out: Directory nonexistent
I have also attempted to alter the startup script at /etc/init.d/tomcat7 as I am using service to start/restart tomcat7 to no avail...
我还尝试更改 /etc/init.d/tomcat7 中的启动脚本，因为我正在使用服务来启动/重新启动 tomcat7 无济于事...
What am I doing wrong?
我究竟做错了什么？

In Ubuntu 12.04+ there is a section like this in /etc/default/tomcat7:
在 Ubuntu 12.04+ 中有这样一个部分/etc/default/tomcat7：
# To enable remote debugging uncomment the following line.
# You will then be able to use a java debugger on port 8000.
#JAVA_OPTS="${JAVA_OPTS} -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"
So just uncomment it and run sudo service tomcat7 restart.
所以只需取消注释并运行sudo service tomcat7 restart。

Settings required in Tomcat:
Tomcat 中需要的设置：
1)Create setenv.sh file under */tomcat/bin/. The location will be same as the catalina.sh file
1)在*/tomcat/bin/下创建setenv.sh文件。该位置将与 catalina.sh 文件相同
2)Place the below content inside it.
2）将以下内容放入其中。
export CATALINA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n" Now start the Tomcat server. Once it is started please proceed with the below steps.
export CATALINA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n" 现在启动Tomcat服务器。启动后，请继续执行以下步骤。
Settings required in Eclipse:
Eclipse 中所需的设置：
3)In Eclipse go to Windows-->Preference--> General-->Network Connection --> Active Provider should be Direct. After changing to direct restart the eclipse.
3) 在 Eclipse 中，转到 Windows--> 首选项--> 常规--> 网络连接--> Active Provider 应该是 Direct。改完后直接重启eclipse。
4)In eclipse right click on project and debug as ->debug configuration ->Remote java application ->Create new configuration.
4）在eclipse中右键单击项目并调试为->调试配置->远程java应用程序->创建新配置。
Fill the below fields
填写以下字段
Name: as your wish
名称：如你所愿
Project: Select the project which you need to debug.
项目：选择需要调试的项目。
ConnectionType: Standard socket attach
连接类型：标准插座连接
Host: Localhost Port: 8000(It should be same as mentioned in point 2)
主机：Localhost 端口：8000（应该和第2点提到的一样）
Then click debug.
然后点击调试。
The debug will start at port 8000. Now you can verify by keeping breakpoints.
调试将从端口 8000 开始。现在您可以通过保留断点来验证。
