How to start debug mode from command prompt for apache tomcat server?

Question

I want to start debug mode for my application. But I need to start the debug mode from command prompt. Is it possible ? And will the procedure vary between tomcat 5.5 to tomcat 6.?

Answer 1

On windows

$ catalina.bat jpda start

On Linux/Unix

$ catalina.sh jpda start

Answer 2

For windows first set variables:

set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket

to start server in debug mode:

%TOMCAT_HOME%/bin/catalina.bat jpda start

For unix first export variables:

export JPDA_ADDRESS=8000
export JPDA_TRANSPORT=dt_socket

and to start server in debug mode:

%TOMCAT_HOME%/bin/catalina.sh jpda start

Answer 3

1. From your IDE, create a remote debug configuration, configure it for the default JPDA Tomcat port which is port 8000.

2. From the command line:

   Linux:

    cd apache-tomcat/bin export JPDA_SUSPEND=y ./catalina.sh jpda run

   Windows:

    cd apache-tomcat\\bin set JPDA_SUSPEND=y catalina.bat jpda run

3. Execute the remote debug configuration from your IDE, and Tomcat will start running and you are now able to set breakpoints in the IDE.

Note:

The JPDA_SUSPEND=y line is optional, it is useful if you want that Apache Tomcat doesn't start its execution until step 3 is completed, useful if you want to troubleshoot application initialization issues.

Answer 4

简短的回答是在 JVM 启动时添加以下选项。

JAVA_OPTS=" $JAVA_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8080"

Answer 5

First, Navigate to the TOMCAT-HOME/bin directory.

Then, Execute the following in the command-line:

catalina.bat jpda start

If the Tomcat server is running under Linux, just invoke the catalina.sh program

catalina.sh jpda start

It's the same for Tomcat 5.5 and Tomcat 6

Answer 6

These instructions worked for me on apache-tomcat-8.5.20 on mac os 10.13.3 using jdk1.8.0_152:

$ cd /path/to/apache-tomcat-8.5.20/bin
$ export JPDA_ADDRESS="localhost:12321"
$ ./catalina.sh jpda run

Now connect to port 12321 from IntelliJ/Eclipse and enjoy remote debugging.

Answer 7

There are two ways to run tomcat in debug mode

1. Using jdpa run

2. Using JAVA_OPTS

First setup the environment. Then start the server using following commands.

 export JPDA_ADDRESS=8000 export JPDA_TRANSPORT=dt_socket %TOMCAT_HOME%/bin/catalina.sh jpda start sudo catalina.sh jpda start

refer this article for more information this is clearly define it

Answer 8

If you're wanting to do this via powershell on windows this worked for me

$env:JPDA_SUSPEND="y"

$env:JPDA_TRANSPORT="dt_socket"

/path/to/tomcat/bin/catalina.bat jpda start

Answer 9

Inside catalina.bat set the port on which you wish to start the debugger

if not "%JPDA_ADDRESS%" == "" goto gotJpdaAddress
set JPDA_ADDRESS=9001

Then you can simply start the debugger with

catalina.bat jpda 

Now from Eclipse or IDEA select remote debugging and start start debugging by connecting to port 9001.
