在ubuntu服务器中为Tomcat7设置JPDA [英] Setting up JPDA for Tomcat7 in ubuntu-server

问题描述

我正在尝试在ubuntu中为Tomcat7设置JPDA。

我已经使用apt-get方法来安装Tomcat7。

通过尝试编辑/ usr / share /tomcat7/startup.sh文件包含以下几行，我尝试使tomcat7进入调试模式并允许通过Eclipse进行远程调试。

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.

 JPDA_TRANSPORT="dt_socket"
 JPDA_ADDRESS="8000"
 exec "$PRGDIR"/"$EXECUTABLE" jpda start "$@"

编辑startup.sh文件后，我使用以下方法重新启动tomcat7：

After editing the startup.sh file, I reboot tomcat7 using:

 sudo service tomcat7 restart

然后尝试使用IP地址以eclipse连接到tomcat jpda端口8000。我从Eclipse收到连接被拒绝错误。

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.

我试图使用startup.sh脚本而不是像我这样的服务可执行方法来手动启动tomcat7。以为startup.sh可能没有被调用。

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.

sudo ./startup.sh

此操作失败，并显示以下输出：

This failed with the following output:

 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

我还试图更改/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，但无济于事...

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...

我在做什么错了？

推荐答案

在Ubuntu 12.04+中有一个部分在 / etc / default / tomcat7 中是这样的：

In Ubuntu 12.04+ there is a section like this in /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"

所以只需取消注释并运行 sudo服务tomcat7重新启动。

So just uncomment it and run sudo service tomcat7 restart.
