    Hi

    Did you put the required jar file into lib folder of your application.

    for more check this pdf

    https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/user-interface-technology/wd%20java/7.0/ui/using%20business%20graphics.pdf

    thanks

    Hi Suman,

    Generally, the reason you receive such an exception is that your application misses

    runtime reference to the component that contains the class mentioned in log...like in

    your case the log mentions it could not find the class definition for class - IWDAbstractChart.

    To make the runtime interface reference could you try the following?

    1) Right-click your WD project.

    2) Select 'Properties' > 'Web Dynpro References'> 'Interface References'

    3) Add class

    4) Apply and OK

    5) Build the project and run.

    Regards,

    Anagha

    Hi Suman,

    You get such NoClassDefFoundError when you have upgraded one of either NWDS or WAS.

    As in other thread java.lang.NoClassDefFoundError, it is recommended both NWDS & WAS should of same version (It may work sometimes in some cases if there are not major changes in the SPs).

    Kind Regards,

    Nitin

      Yes Suman. Please upgrade your NWDS to the same level as WAS. The libraries will then be there & the class not found problem should resolve.

    Hi Suman,

    Yes, please upgrade your NWDS to SP13 version.

    After upgrade, please start your NWDS in a fresh new workspace (starting in same older workspace can lead to metadata corruption as the older plug-in classes are already loaded there).

    You will need to import your project from the earlier workspace (so dont delete older workspace or keep a copy of the project in case you want to delete the older workspace)

    This should solve your NoClassDefFoundError.

    Kind Regards,

    Nitin

      Hi Suman,

      If the java.lang.NoClassDefFoundError error is finally resolved by upgrading your NWDS do let us know the same.

    Hi,

    After logging to Service market place, go to installation and upgrades->support packages and patches->sap netweaver->sap netweaver 7.0->entry by component->developer studio->NW Developer studio7.0.

    Hope it helps.

    Thanks,

    Prasanthi.

      Tell us the complete procedure.

    Hi Suman,

    After downloading the required service pack SP13 from SAP Service Marketplace, you will find a setup exe file in the downloaded content. Just run this exe. You will get a wizard with different options for Upgrade, Uninstall.

    You can choose Upgrade option & continue.

    Alternatively, you can choose Uninstall option & first remove the previous uninstallation. After uninstalltion, check that the eclipse folder at installation path (default path should be "C:\Program Files\SAP\IDE\IDE70\eclipse") is empty. Then again run the exe & do a fresh installation.

    After upgrading NWDS, start the IDE in a fresh new workspace (to avoid corruption of metadata due to old classes already loaded in older workspace)

    Hope this helps you.

    Kind Regards,

    Nitin
