Answer 2

For the first Windows variables:

 set JPDA_ADDRESS=8000 set JPDA_TRANSPORT=dt_socket 

To start the server in debug mode:

 %TOMCAT_HOME%/bin/catalina.bat jpda start 

For the first export unix variables:

 export JPDA_ADDRESS=8000 export JPDA_TRANSPORT=dt_socket 

and start the server in debug mode:

 %TOMCAT_HOME%/bin/catalina.sh jpda start 

Answer 3

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

• At the command line:

  Linux:

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

  Window:

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

• Set up remote debugging from your IDE, and Tomcat will start, and now you can set breakpoints in the IDE.

Note:

The JPDA_SUSPEND=y is optional, useful if you want Apache Tomcat to not run it until step 3 is completed, useful if you want to fix problems with application initialization.

Answer 4

The short answer is to add the following parameters when starting the JVM.

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

Answer 5

First go to the TOMCAT-HOME/bin .

Then run the following command at a command prompt:

 catalina.bat jpda start 

If the Tomcat server is running Linux, just run catalina.sh

 catalina.sh jpda start 

Same for Tomcat 5.5 and Tomcat 6

Answer 6

There are two ways to start Tomcat in debug mode.

1. Using jdpa run

2. Using JAVA_OPTS

Set up your environment first. Then start the server using the following commands.

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

refer to this article for more information, this clearly define it

Answer 7

These instructions helped 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 8

Inside catalina.bat, set the port on which you want to run the debugger

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

Then you can just start the debugger with

 catalina.bat jpda 

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