SAP Portal Webdynpro Java Project from ear,


  • We have an old WD Webdynpro java project that is deployed on enterprise portal. We need to make changes to the code now. We downloaded the copy of the EAR using offline config tool. It contains the file. However, we are not able to import the same in NWDS.

  • We need to understand the way/steps to create the project from the source

  • We have no copy of the *.sca files to import back, no one has taken the backup before.

Please let me know if you have any ideas on this scenerio.

    Hello Vikas,

    Extracting a deployed SCA and editing it is NOT supported scenario.

    The supported by SAP way is to use NWDI and import a development configuration in the NWDS.

    Then you might change the source code and with the help of CMS, to deploy it to the RTS.

    In case you do not have this SCA in the DTR, then you might try to import a development configuration and manually to create DCs .

    These documents might come handy.

    Dear Vikas,

    Hope you are doing good.

    There is no standard procedure to recover lost code using the as the SCAs are not preserved while being deployed on the target system. It is possible that under the following path you will find the war-files that have been deployed:


    Depending on the build option used when building the archives in NWDI, these may contain files called ''.
    The official recommendation is to proceed as per Milen's advise.
