Hello Folks,


While writing this blog I myself get this feeling that I am doing something really outdated and makes we wonder why I or someone has not written yet. May be it was too obvious for the people. But then is it really so obvious?

I happened to see few questions around it on SCN Q&A, also I myself had to read code of some standard modules for getting to know certain parameters. I happened to go through this blog too. And then I realized for whom it is not so obvious,

  • People with limited knowledge to access the OS level of SAP servers and with limited knowledge of how the server structure looks like (Hardly anyone gets the access).

  • People really not pro in Java and EJBs in SAP AS Java servers.

So it made me land up here writing an outdated blog which I or anyone should(could) have written half a decade back. I am showing a sample for the popular MessageTransformBean module. So here's how do we do it in a non-pro way


  • Navigate to NWA-> Configuration->Infrastructure->Application Modules

  • Filter on Type=EJB Module, search for jar starting with and look JNDI names. By JNDI names you will come to know which module you are looking at

Just another example


  • Once you copy the name of jar as shown in screenshot navigate to - Navigate to NWA-> Configuration->Infrastructure->Java Class Loader Viewer

  • Type the name (copy) in component name and hit enter

  • Go to the Resources tab and you have located the physical location of the jar file for the module


  • If you have access to the OS level then great. If you don't simply ask basis team to download and give you this jar file

  • Once you have the jar file you can go for java decompiler tool. I go for jd-gui requires no installation and no hustle from below link

download the zip version for windows

  • Extract and Run

  • You and simply drag and drop the jar or open jar with it and you will see the code.


That is all it was a short and sweet blog (not for the experts out there). I tried searching for contents related to this to be sure I am not violating the rules of engagement 😉 ;).


Hope it helps few folks!
