How to specify a base class for Remote Interface in Workshop 9.2? -- URGENT

Hi,
I am trying to create a UUP EJB in WebLogic 9.2 workshop. I am using @FileGeneration to create my home & remote interfaces. And the generated remote interface is extending javax.ejb.EJBObject;I want my remote interface to extend com.bea.p13n.property.EntityPropertyManager which in turn implements javax.ejb.EJBObject. Can someone tell how i can do it in Workshop?.
I came across Predefined Variable: remote.baseClass and as per docume
ntation..."If specified, the value of this variable will be used as the base class for all generated remote classes. Where i should specify it?. @FileGeneration does nt have any option for it. Any help is grtly appreciated.
Following are my code snippets:
IMPL Class
@FileGeneration(remoteClass = Constants.Bool.TRUE,remoteHome = Constants.Bool.TRUE, localClass = Constants.Bool.FALSE, localHome = Constants.Bool.FALSE,remoteClassName = "MyEntityPropertyManager",remoteHomeName = "MyEntityPropertyManagerHome")
public class MyEntityPropertyManagerImpl extends GenericSessionBean implements
          SessionBean {
//code
}

This question was posted to both the bea.workshop.developer.general and weblogic.developer.interest.workshop (I had replied to the later on 10/19); after seeing an identical question today on this list want to include a reference to that reply here:

  • AS3: How to create one base class for classes loaded in multiple swfs?

    Our application have 3 different modules and all use
    fscommand and ExternalInterface alot. Now the problem is we are
    combining all those modules, but they all will reside in different
    swfs. Is there any way that they extend to same base class and its
    static members have only one instance accessible by all
    three?

    Hi,
    You can achieve this via Workshop 9.2 by using the exported Ant script for your project as follows:
    -Ensure that all Jars needed to resolve com.bea.p13n.property.EntityPropertyManager (this particular class is found in weblogic92/common/p13n/lib/p13n_ejb.jar) and all referenced classes are added to the Java build path for your WebLogic EJB project (Properties->Java Build Path->Libraries)
    -Export the "Workshop Ant Script" for your WebLogic EJB project (File->Export->Workshop Ant Script); this will generate a "build.xml" Ant script under your project root directory.
    -Edit this default build script as follows: in the call to the "ejbgen" task within the "build" target, add the attribute: propertyFile="ejbgen.properties"
    -Create a file "ejbgen.properties" under the root of your WebLogic EJB project and add the following entry:
    YourSessionBeanClassName.remote.baseClass=com.bea.p13n.property.EntityPropertyManager
    -Add a "<path refid="java.classpath"/>" within the "<classpath>" for the "java" task element that calls "weblogic.ejbc" (this will ensure that the p13n classes are resolved by EJBC)
    Follow the instructions for executing the Ant build script found here: http://edocs.bea.com/workshop/docs92/ws_platform/ideuserguide/conUseCustomAntBuild.html
    For more information on the EJBGen property file support, see: http://e-docs.bea.com/wls/docs92/ejb/EJBGen_reference.html

    Hello,
    Before to use remote assistance in windows 8.1, i need to configure my nat router freebox.

    How to use a fixed port for remote assistance ini windows 8.1 ?
    And why i can't use easy connect ?
    i read that the router must implement the PNRP protocol. I think it's a propriatary microsoft's protocol unknow on my router.

  • So how to specify different answer file for different install images in WDS snap-in?

    hello
    in WDS snap-in, in properties on server name, on client tab, we can define an answer file for unattended windows installation on WDS clients.
    my question is, maybe we have added multiple images in WDS snap-in (win xp image, win 7 , win 2008,...)
    now this one answer file applies to all of them ?
    so how to specify different answer file for different install images in WDS snap-in?
    thanks in advanced 

    Under the "Client" tab of WDS, you should only use an answer-file with settings relevant for the installation. This would be credentials for the WDS deployment share, international settings used during the setup and possibly also destination drive
    details (if you want the installation to take care of partitioning the disk etc). The settings relevant for unattend-files used under "Client" would only be of those in phase 1 (WinPE).
    However, if you would like to have specific unattend file for every installation, e.g. Win7, Server 2008, Win 8 etc, you can browse to the image under "Install Images" under the image Groups. There you can select properties for every image and
    have a personal unattend-file.
    hi Joel
    very cool. thanks a lot, that really helped me.

  • How to specify the XML Declaration for an XML variable

    I need to set the XML declaration for my XML variable as

    expecting the declaration. Can somebody help me with this?
    Thanks

    I work mostly with the Java versions of the parser so you'll have to make the translation to C++. As far as I know, you can't use the SAX API to access to the encoding.
    You need to use the DOM along with Oracle's extension to the basic DOM functionality. Oracle's package, oracle.xml.parser.v2 defines a class which implements the Document interface called XMLDocument. This class has a method, getEncoding(), which returns the encoding. You would use the method in getDocument() in the Parser base class inherited by DOMParser to retrive the XMLDocument.

  • Using base classes for common attributes

    Can TopLink handle use of non-mapped abstract base classes? There are a number of fields that are common to each and every one of my domain objects which, following good OO design principals, are moved up to a common superclass. So I have:
    public abstract class AbstractDomainObject
    private Integer id;
    private Date dateCreated;
    private Integer creatorId;
    private Date dateModified;
    private Integer modifierId;
    // ... appropriate attribute accessors
    Then a concrete class which gets mappped in Workbench:
    public class Address
    extends AbstractDomainObject
    ... specific attributes
    I tried mapping all the specific attributes explicitly defined in the Address class and then using "Map Inherited Fields > To SuperClass" in Workbench. However, when attempting to test my mappings in the SessionConsole, only the attributes explicitly defined on Address are present in the SELECT clause.
    Can what I am trying be done? If so, how?

    Steve,
    What you are trying to do is very common and the process you described is exactly how map the class. I will summarize a couple of points for mapping this scenario.
    1. You only need to import Address in and map it. If AbstractDomainObject is imported into the Mapping Workbench make sure that it is disabled. The abstract class is only required on the project's CLASSPATH.
    2. You should not enable inheritance for the Address class. Inheritance is for situations where the abstract base class has its own independent table. I am assuming that your Address class has its own table that contains fields for all of the attributes it needs along with those of the abstract base class.
    Assuming these conditions are met then TopLink will work fine with you Address class just as if it had all of the inherited attributes directly.
    If you are still having trouble take a look through your generated project (XML or Java) to ensure that mappings exist in Address for All attributes. If the project looks good then I am at a loss. Customers have been using this pattern of use for over 5 years with TopLink and Java inheritance.
    Cheers,
    Doug

  • ClassFileTransformer and how to transform the base class first

    Hello,
    I've written a ClassFileTransformer that uses ASM to enhance classes at load time.
    But some of the enhancements depends on possible enhancements to the super class.
    Example: under some coditions a method doWork() is inserted. This method did not exist in any class (doWork is just an example, I use a name that is not accepted by the compiler but allowed by the JLS).
      public class A {}
      public class B extends A {}If the method doWork() was inserted into class A, then the doWork() of B has to call doWork() of class A:
       super.doWork().Currently I try to load the base class by using
       loader.loadClass(superName.replace('/', '.'));this loads the super class but without passing my transformer !
    How can I solve this ?

    Looking at the comments in ClassFileTransformer.java and the code in ClassLoader, it seems the transformers are called only for class files that get a ClassFormatError. Transformers are intended to fix old broken/incompatible class files on the fly.
    I guess the intended way to do what you are doing is to define a custom class loader. Read class into byte[], transform, call defineClass() on the transformed byte[]. Google for java custom class loader for examples.

  • How to use inbound exit class for more than one workflow step

    Hi All,
    In Offline Workflow Approval Scenarios where the work items are sent to outlook of non sap users inbox through workitem exit of the respective workflow item. Based on the user reply from outlook email(either approve or reject) which sends an auto reply to Offline user . We configure an inbound exit class and assign the same in the SMICM transaction. Based on the code written using SAP_WAPI function modules in inbound class exit offline user gets the user approval result and performs the action in SAP.
    My question now Is how can we use this inbound exit class for all the steps of a workflow.
    For ex: In a workflow I have a decision step followed by an activity step. First I will write the work item exit for the user decision step and inbound exit code for the user decision step and offline user executed the user decision step with approve action.
    followed by that I have an activity step for that I will code a work item exit for that activity level but how can I user the same inbound exit class for the activity step as well .
    Quick reply  would be of great  help for me.
    With Best Regards,
    Veni

    For the outbound processing you have the option of replacing the workflow exit by chancing the bsp application of the extended notification (see note 1448241 solution as an example of how to do the change) and replacing the standard links with a "mailto:...".
    As far as the inbound processing, that depends on what should be done in the activity step, if for example you have a bapi which executes what the user does you can call it in the inbound class instead of the user and then the relevant wapi (complete the workitem/raise event etc.).

  • How to generate the trace files for remote db link session's?

    User are complaining, the db link queries are performing slowness..
    how to enable the sql trace session for db link's in remote database...
    Is there any way to enable sqltrace for the dblink session ?
    if not how to enable the sql trace for entire database level, rather than session based...

    An explain plan of the SQL being ran on the local database will review the SQL being passed to the remote db. You can then explain that SQL on the remote db.
    I have had to tune a few distribued queries so more than likely the explain plan alone will be enough to allow you to tune the query to improve performance. If not then you can go to the trouble of trying to set up dual traces.
