Problem when Creating Project (Composite Application Services) in NWDS

I've seen a few posts regarding this but I don't feel as if any real solution was given.
I just installed Netweaver Developer Studio (7.0.15) with the current JDK/JRE (1.6.0_07).  When trying to create a new Composite Application Services project within the Studio, using the new project wizard, I get an error: Problem when Creating Project.
I get the EJB Module and Dictionary to create within my navigator with no problems, however, during the creation of the metadata, the error occurs.  I do have the metadata folder appear within the navigator, but nothing in it.  None of the other three items are created.
I have tried the attempt at deleting the metadata folder within my workspace directory and trying again but the same exact result occurs.
Is there any other solution out there for this problem besides attempting to find older versions of NWDS, etc. that are more "stable"?
Thank you!

Durga,
Very simple but effective solution.
I had tried uninstalling / re-installing NWDS with no effect but uninstalling / re-installing NWDS AND all java related products on my machine did work.
Note: For anyone else with this issue in the future.  I installed the Java SDK / JRE 1.4.2_18 with NWDS 7.0.15 in case this is also a possible issue with versions.
Thanks, Durga!

  • Error when trying to create a Composite Application Services project

    Hi Experts,
    I am facing a problem while trying to create a project using NWDS 7.0 SP 13
    New Development Component Project-> Composite  Application Services
    then pressing finish, it throws an error as follows
    "Generation can not completed due to one or more error"
    Reason :
    Errors occurred during code generation
    Warning :
    EAR-META-INF generation failed : null
    Plz help me to solve this
    Thanks in advance,
    John

    Hi John,
    It looks like there might be issue with CAF services related plugins. Check if there are any errors in log file under metadata folder of your workspace.Try deleting the metadata folder & restart the NWDS or start in a new workspace.
    I feel if the issue persists, it is a bug & you can raise an OSS ticket.
    Kind Regards,

    Hi Chandan,
    I still encounter the error message and this time, it only create the ejbmodule folder. In mine previous creation, I have dictionary, ejbmodule, metadata and webdynpro.
    I realised that there is some different in the .plugin folder and the previous .plugin folder of the .metadata.
    Not sure whether is it affected by the .plugin folder. Is there a list of .plugin required?
    can advise?
    Thanks again.

  • Exception in calling a web service from a composite application service

    Hi,
    I have created a composite application service with external service as a web service. My web service is deployed on localhost as well as I am running my composite application service in localhost. When i try to test the application service, I get the exception
    com.sap.caf.mp.base.exception.InvocationException: Invalid parameters
    The exception happens in MPConnector.java 'process' method where I am calling the execute operation on the service.
    I have tried testing this through Service Browser as well as creating a callable object on the Application service and testing the callable object.
    I am using the NWDS 7.0.06 version
    and EP installed on my machine is the Sneak Preview 7.0 sp 7
    Will appreciate all help in this regard.
    Thanks,
    Prachi

    Hi Navneet,
    I have verified the input/output parameters. They are simple types. All are Strings. Nothing really complex there.
    I have the Service Exceptions added already.
    And definitely the permissions are disabled but still this isn't working.
    Any more clues might be helpful.
    Thanks,

  • Field not set: ParentEPSObjectId when creating Project.

    Hi everyone,
    I'm developing .net application and getting data from primavera by using p6 web service. At the moment I stuck on project creation. I'm using following code to create a new project:
    Public Function CreateOneProject(pProjectName As String, pProjectId As String, pParentEpsObjectId As Integer, pPlannedStart As Date, pPlannedFinish As Date, pParentOBSObjectId As Integer) As Integer
         Dim vNewProject As Project()
         vNewProject = New Project(0) {}
         Dim vProject As New Project()
         vProject.Name = pProjectName
         vProject.Id = pProjectId
         vProject.ParentEPSObjectId = pParentEpsObjectId
         vProject.StartDate = pPlannedStart
         vProject.FinishDate = pPlannedFinish
         vProject.OBSObjectId = pParentOBSObjectId
         vNewProject(0) = vProject
         Dim retVal As Integer() = gProjectService.CreateProjects(vNewProject)

  • What is Composite Application Services?

    Dear Experts
    What is Composite Application Services? What is it's use?
    How can I create one?
    Please give some sample scenarios so that I can try working it out.
    Regards
    Aparnna

    Hi Aparnna,
    You should use CAS or SAP Netweaver Composite Application Framework when you want to develop a composite application based on Netweaver platform. By composite application means an user-centric application based on a business process which is composed by services provided by backend legacy or enterprise systems. In CAF/CAS perspective in NWDS you can create a CAF core project and define your business entities with its corresponding access and lifecycle methods. These methods can be exposed as web services to be consumed by the CAF UI like Web Dynpro or Visual Composer.
    For more information on CAF please refer the following links:

    Hi Khaleel,
    Do you see only this message or do you also see something like below:
    CreateWssSiteContent: Creating project site failed! Project Uid=8e180c10-5433-4424-a236-54ea989872fa, site URL=http://PROJECT.test.com/PWA/AAAtest1000, site name=AAAtest1000. Microsoft.SharePoint.SPException: The site template requires that the Feature {e8389ec7-70fd-4179-a1c4-6fcb4342d7a0}
    be installed in the farm or site collection. at Microsoft.SharePoint.Utilities.SPUtility.ThrowSPExceptionWithTraceTag(UInt32 tagId, ULSCat traceCategory, String ......
    So, if you see the above message, its a feature that is missing. How many servers do you have in the farm? Do you have a separate project application service server?
    In that case you will have to copy the feature under "14\TEMPLATE\FEATURES" features folder from WFE to application server also. This is because when creating a project workspace, PSI will refer to this feature on application
    server and since it is not present in application server, it fails creating the site.
    Happy troubleshooting.....

  • Error during creation Composite Application Service

    Hello!!
    In SAP NetWeather Developer Studio we create CAS(Composit Application Service), then we create ENTITY and make GENERATE ALL PROJECT CODE. If CAS is created locally, there are no errors during generation, but if it is created non-locally, an errors occurs with JDO.
    1) The project was not built since its classpath is incomplete. Cannot find the class file for javax.jdo.PersistenceManager. Fix the classpath then try rebuilding this project.
    2) This compilation unit indirectly references the missing type javax.jdo.PersistenceManager (typically some required class file is referencing a type outside the classpath)
    Thank You!!

    Hi Vadim,
    Please uninstall your NWDS and java and reinstall them.
    This may solve your problem.

  • Error when creating a FDM application on SQL Server 2005

    Hi,

    Based on the error message it appears to be having a Shared Services issue. Verify that the "ADMIN" account is being used for the HSS connection and that you are using "ADMIN" to create the application and see if the same error is returned.

  • Problem when creating Database (Database, OS and hardware Configuraiton included)

    Problem when creating Database:
    Below are the problems, which I faced during creation of database. I have mentioned both the problem separately. Plus the log file maintained by Oracle during installation. It might help in diagnosing the error. Plus a little conclusion with I turned up to.
    There are two problems, when creating database with Oracle Database Assistant. One when creating pre tuned database from CD. And second when creating customized database giving options your self.
    Problem # 1:
    When creating pre tuned database from CD. The process of creating Database is 90 % complete and is at step # 3 Initializing Database. It gives error ORA-03113: end-of-file on communication channel.
    I searched following oracle help for this problem.
    ORA-03113: end-of-file on communication channel
    Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two-task software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.
    Action: If this message occurs during a connection attempt, check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server. If the message occurs after a connection is well established, and the error is not due to a physical failure, check if a trace file was generated on the server at failure time. Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.
    Conclusion:
    What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.
    Problem # 2:
    When creating database with custom option. The process of creating Database is 2 % complete and is at step # 2 Creating Database Files. It gives error ORA-12571: TNS:packet writer failure.
    I searched following oracle help for this problem.
    ORA-12571: TNS:packet writer failure
    Cause: An error occurred during a data send.
    Action: Not normally visible to the user. For further details, turn on tracing and re-execute the operation. If error persists, contact Worldwide Customer Support.
    Conclusion:
    What I conceive from this problem and the help available is that, I have to install NET8 again. But I am not sure about the solution, please tell me whether I am rite or not.

    Dont't worry about that. Before you
    create a table(or view), it is wise to
    drop the table(or view) with the same name.
    If the name doesn't exist, of course there
    is an error message. See the following script:
    -------------------begin-----------
    drop table students cascade constraints;
    create table students (
    sid varchar2(5),
    fname varchar2(20),
    lname varchar2(20) not null,

    primary key (sid));

  • GenericServiceFactory initialization problem when trying to load Web servic

    Hi,
    I am making a Guided procedure that calls a webservice. I have created a new Destination Template and was able to load the webservice definition successfully, but when I test the callable object I created for that same webservice y get the error:
    GenericServiceFactory initialization problem when trying to load Web service model for WSDL.
    Somehow I think there is something wrong with the user authentication. The Destination template has a user and password but somehow I think the callable object test is not using this information at all.
    Can anyone help ?
    Thanks in advance

    Hi Hans,
    Have you verified if you can call any external web service calls from your J2EE engine?  Go into the SOA Management / Global settings (if you are on CE - if you're on 7.0 it's in manage WS desintations).
    Look at your proxy settings and set them like your web browser that enables external calls.  For example, in the SAP network I set my global proxy settings on my local J2EE engine to be:
    Proxy host:  proxy
    Proxy port: 8080
    Exclude list:  *.sap.corp
    Does that make sense - have you verified if your settings are correct for your company?
    Regards
