Overview
In this article, we'll cover how to debug the SAP Hybris application remotely using Eclipse.
Start Hybris in Debug Mode
The Hybris installation comes with startup scripts for Windows and Linux.
Windows
C:\>cd %HYBRIS_HOME%\bin\platform C:\Apps\hybris\bin\platform> hybrisserver.bat debug
Linux
$ cd ${HYBRIS_HOME}/bin/platform
$ ./hybrisserver.sh debug
Configure Eclipse
Launch Eclipse and go to Run -> Debug Configurations
Right-click on Remote Java Application and select New
Choose a name and select the Hybris code project. Change localhost to the hostname of the machine running the Hybris app in debug mode.
Click the Debug button on the bottom of the dialog screen. This will hook Eclipse with the Hybris server that is running and listening on port 8000.
Open the Debug perspective. We can now set breakpoints in our code to begin debugging.
Debugging Exceptions during Hybris Startup
Sometimes we need to debug an exception that occurs during startup.
In this situation, we need to tell Tomcat to wait for a remote debugger to connect before continuing with its startup routine.
This can be accomplished by modifying bin\platform\tomcat\conf\wrapper-debug.conf and setting suspend=y:
wrapper.java.additional.22=-Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=y
Troubleshooting
Failed to connect to remote VM. Connection Refused
If you're seeing this error in Eclipse, make sure Tomcat is running in debug mode:
The configuration is under bin\platform\tomcat\conf\wrapper-debug.conf
In this file, there should be entries to tell Tomcat to run in debug mode:
wrapper.java.additional.20=-Xdebug wrapper.java.additional.21=-Xnoagent wrapper.java.additional.22=-Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n
