Using External Library in Mobile Web Dynpro Offline

Question

Hi all,
i would like to use a jar in a Mobile Application for Handheld and i followed the steps from the wiki "Using External Library in Mobile Web Dynpro Offline" at
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/home/usingExternalLibraryinMobileWebDynpro+Offline
>How to use External Library in Mobile Web Dynpro Offline
>For using external jar in local deployment scenario, one can do following:
>1. In the dc where jar has to be used, add the jar as external jar classpath entry. It can be done via <dc> > (Right-click)> properties->Java Build Path->Select "add external jar".
>2. Do the programming using the jar.
>3. Shut down the mobile client.
>4. Copy the jar in the "lib" folder of mobile client installation.
>5. Deploy the application in the IDE.
>6. Run the application.
>In 5, the jar will not deployed and will be picked from the lib folder during 6.
>...
>Note: This will work on and after SAP Net Weaver CE 7.1 SR3 with Mobile plugins from CE 7.1 SR3 (and after).
i get a error at the deployment with the message "...package myres does not exist...":
    >echo:     C:Documents and SettingsTPCompworkspace.jdiLocalDevelopment     4CDFCC9F800D44D0F2B7FEDE7245CFB5gen_oca

     >javac: ERROR: import myres.TestA;
there is only sap.comtcmobileocaapi~api.jar in the class path and myres.jar was not added.
how can i fix my problem or does the steps in the wiki not work yet for SAP Net Weaver CE 7.1 SR3 with Mobile plugins from CE 7.1 SR3 ?
Thanks,

Hi,
1) in Development Infrastructure Perspective -> rightklick in Navigator/Projekt Explorer  -> new Project  -> (Development Infrastructure)  Development Component (DC).
NWDS generates Project Ressources e.g. the folder "libraries"
2) copy the jars to the "libraries" folder.
3) rightklick on the newly created Development Component (DC) ->  Development Component -> Show In ->  Development Properties -> go to the Tab "Public Parts",
in -> "Defined Public Parts" -> klick on Button "Add" -> give a name for "Public Part" -> at "Purpose" select "Compilation" -> Finish.
rightklick on the newly created Public Parts -> select  "Manage Entities" and select the jars you want to use -> Next -> Finish.
4) switch to the Mobile Apps for Handhelds Perspective ->  in Development Component  select e.g. the Service Component or the UI Component ->
rightklick ->  Development Component -> Show In ->  Development Properties -> got to Tab "Dependencies" -> klick on Button "Add"  -> under the Node MyComponents -> select the newly created Development Component with the Public Parts/jars (that was created in 1 - 3).
thats all, now you can deploy your application
