Dynamic Proxy Classses Generation

Hi All,
i am getting an exception while running the Sample Application Given By the Oracle for Dynamic Invocation of Web Services with wsdl URl..
The Link For the Client Application is
http://fgvspnet.fgvsp.br/ojspdemos/servlet/ViewSrc/src/oracle/j2ee/ws/client/impl/WSClientBean.java
The Exception is
oracle.ds.v2.adaptor.AdaptorException The SOAP PA Receives SoAP Fault from the Server Missing Body Information....
Any Clues how to resolve this?
Regs,
Veeru

Hi Veeru,
I am getting this error and I have a simple service that takes a String as input and returns a String back. I am able to read the service from the registry but when the invoke is called on the method, I am getting this error. Were you able to figure out this issue, I belive you had similar issue.

  • Dynamic crystal report generation - issues with column headings

    Hi All,<br>
    I'm trying to generate a crystal report dynamically based on a "result set" data(Query: select REPORT_ID, REPORT_NAME, REPORT_DESC, RPT_FILE_NAME, LOCATION from IRS_REPORT_DETAILS).

    appreciate your help.

    IField field = table.getDataFields().getField(i);
    Here you are getting the first field in the array.  This may not be the field you want to add since we aren't sure how the arrays are ordered when retrieving fields from the report.  It is better to retrieve the fields with the findObjectByName method, thus ensuring you are retrieving the field you want to add to your heading.

    If you are using document/literal, which this WSDL is, you would be much better off using Metro (JAX-WS) as it has a much better dynamic interface in the Dispatch APIs. Metro: http://metro.dev.java.net, JAX-WS: http://jax-ws.dev.java.net.

  • Jax-ws: dynamic proxy-suppress weblogic's default ws-policy handling

    hi all,
    i am writing my own jax-ws client (dynamic proxy) to call a web service, secured by usernametoken profile.
    the wsdl of the web service do include the ws-policy information.
    sample client side code:
    URL url = new URL("path_to_wsdl_file");
    QName serviceQname = new QName("http://model/", "CalculationService");
    Service service = Service.create(url, serviceQname);
    //add resolver and jax-ws handler to add username token SOAPElement fragment to the SOAP message.
    the above code runs fine in J2SE 6.0 environment (without any weblogic-specific library).
    but when i run the above code in a servlet (running in weblogic), the above code fails with the following error:
    Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Unable to add security token for identity, token uri =http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken
    at com.sun.xml.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:196)
    at com.sun.xml.ws.fault.SOAPFaultBuilder.createException(SOAPFaultBuilder.java:122)
    at com.sun.xml.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:119)
    at com.sun.xml.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:89)

    at $Proxy23.add(Unknown Source)
    at client.ServiceLocator.main(ServiceLocator.java:32)
    it seems that the weblogic server will try to handle the ws-policy element (according to those in the wsdl), even though
    i have already added the username-token security header by my own code.
    As i don't add some weblogic-specific code (e.g. weblogic.wsee.security.unt.ClientUNTCredentialProvider), the web service call fails.
    is it possible to disable/suppress such behavior (weblogic runtime handle the ws-policy element) per web service call???
    (i don't want a server scope solution, as there may be other web service client running on the same weblogic server that rely on such behavior).
    i don't want to use weblogic's API (e.g. ClientUNTCredentialProvider) as i want my web service client be portable (username token is easy to be handled by my own code)
    thank you.

    Hi René ,
    i just use plain HTTP, not HTTPS.
    seems don't involve any certificate, am i right?
    in J2SE environment, i can run the webservice client without problem.
    but once i run the client in weblogic, the problem mentioned occurred.
    if i manually delete the ws-policy related tag in the wsdl file (i download it to local filesystem for testing), the client can run in weblogic too.
    so, think there is some setting in weblogic that try to handle the ws-policy by its so-called 'credential provider'(e.g. ClientUNTCredentialProvider ?)
    thank you.

  • Dynamic proxy, several instances, same name, diff ids?

    I'm using a dynamic proxy with a simple invocation handler. Using the proxy for several instances of the target object should yield multiple instances of the proxy. In the debugger, each proxy instance is named $proxy0 with different ids. Can someone please elaborate on this? Specifically, the Proxy instance is created using the target object. Thus, how can each proxy instance have the same name, when different target objects (of the same type though) are used to construct the Proxy object? Is the Proxy instance the same regardless of the target object?
    I : interface
    T: target class
    pseudo thing:
    <code>
    T t1, t2, t3 ... new ...
    I i1 = (I) Proxy.newInst...(..., ..., t1)
    I i2 = (I) Proxy.newInst...(..., ..., t2)
    I i3 = (I) Proxy.newInst...(..., ..., t3)
    Each i has name $proxy0 with different id. For instance: i1-> $proxy0 id=68, i2 ->$proxy0 id= 32, etc.
    </code>
    Insight is appreciated!

    is it the same proxy that is instantiated three times (obviously)?It is the same proxy class that is instantiated three times. Obviously. Because that is the only meaning for 'instantiate' in Java.
    But how can that be when the target object for each Proxy instance is different?Because they are three different instances of the same class, each with a different target object.
    What's the problem here?

  • Proxy Object generation error using Wizard for Web Service Consumption

    HI all,
    I am using the Web Service Proxy Object Generation Wizard (via SE80) and have successfully been able to create a Proxy Object for a Web Service which resides on our INTRAnet.
    ...But now I am trying to consume a Web Service out on the INTERnet and I get an error I cannot quite understand when generating the Proxy Object using the URL of the WSDL of the SOAP Web Service.
    The initial error in SE80 simply states "No vendor specified", but when I double-click on the error to get the long text I get the following error:
    Incorrect value: Namespace prefix q1 of QName q1:RequestArray is undeclared
    Exception of class CX_SLIB
    Has anyone seen this or have experience with this?
    I am a senior ABAP-er but have very little experence on the web development side of things so this looks very foreign to me.
    Any input would be GREATLY appreciated!
    Thanks!!
    -Chris

    RESOLVED! ---
    I figured it out with further trial and error...
    Turns out I was using the SOAP version of the WSDL (I had a choice b/ween SOAP, REST, and XML).
    When I simply supply the XML version of the WSDL to the Proxy in the Web Services Wizard, the error vanished and the Proxy Objects generated just fine !!
    ..Closing this problem.

    Hi Eddie,
    Perhaps you might like this one:

    it uses dynamic proxies to achieve complete RMI transparency.
    Something to consider, good luck.

  • Dynamic proxy invokes basic auth web service

    My dynamic proxy client works fine with any web service except the basic auth secured one.
    I know how to use stub client to work around this issue. But I haven't found a way to get around when dynamic proxy clients are used.
    Any idea is appricated. Thanks

    Paula-
    Given that you can work around this issue with the stub client,
    you should be able to work around the issue in the dynamic proxy client
    in the same way-
    I am interested that you say workaround the issue with the stub client.
    Is there a problem that you have noted?
    If you can let me know how you worked this issue with the stub,
    and what problems you have specifically had with the dynamic proxy client
    I will look at the issue to see if it a bug.
    Please let me know what environment you are working in, the version of jaxrpc 1.x,
    what container, jdk or jre and a sample client program that would help me understand
    the problem.
    Thanks,
    Kathy

  • Dynamic proxy on jwsdp 1.1 deserialization error

    Hi,
    I want to use a dynamic proxy to get information from an webservice.
    normal datatypes like String or integer works fine. But when I want to have an object back, I get an deserialization error. I use sdk 1.3.1_08 and the jwsdp 1.1
    Does the jwsdp 1.1 support to transfer objects with dynamic proxy?
    thx
    Matthias

    I must use the jwsdp 1.1 because our clients run on IBM-Webspehre the highest sdk wich is at the moment supported is sdk 1.3.1_08.
    But with the jwsdp and sdk 1.4.2 I became also an exception.
    her it is:
    UrlString = http://localhost:8080/uisservice/endpoint?WSDL

  • JAX-RPC Dynamic Proxy Client Question

    I have a very simple web service successfully deployed using Tomcat 5 and Apache Axis. It simply takes a string and returns a String. Regardless, it's working.
    Now I'm wanting to create a JAX-RPC dynamic proxy client as described on the following page:
    http://java.sun.com/webservices/docs/1.3/tutorial/doc/JAXRPC5.html
    There are numerous other articles out there describing the same method.
    My problem is that I'm getting a ServiceException on the following line every time I try to run my client:
    ServiceFactory factory = ServiceFactory.newInstance();
    Would anyone have any ideas why this might be or what I might be missing? All the articles make it seem like this is just a trivial line and never mention much about it.
    Any help would be appreciated. Thanks.

    Hello,
    You are getting a service Exception on ServiceFactory.newInstance() method?
    Actually, I have never seen this problem before. Is it possible that there are
    classpath issues? That is, are you using just the jars from the jwsdp?
    Regards,
    Kathy

  • How to make a dynamic proxy client in Java ME?

    Hi guys!
    I have an existing static stub web service client to WCF made by generating client stub feature of the Netbeans. How do I make this into a dynamic proxy?

  • No SOAPAction in dynamic proxy client

    I am trying to consume a .NET Web service from a J2EE client. I am using a dynamic proxy client from http://java.sun.com/webservices/docs/1.3/tutorial/doc/JAXRPC5.html#wp79973
    However, I am have a problem with the SOAPAction HTTP header. .NET requires this header element to be set but the proxy sends an empty SOAPAction header. What is the solution to this problem?

    message.getHeaders().addHeader("SoapAction","http://some.action.here");
    this piece of code is not working. This what i'm using.
    my .net service is running at ""http://192.168.4.214/dmwebservice/service1.asmx";" and my method name is "disconnect_cabinet"
    mesg.getMimeHeaders().addHeader("POST" , " /dmwebservice/service1.asmx HTTP/1.1");
    mesg.getMimeHeaders().addHeader("HOST" , " http://192.168.4.214");
    mesg.getMimeHeaders().addHeader("SOAPAction", " http://tempuri.org/disconnect_cabinet");

  • Using Dynamic Proxy in AppServer 7 during EJB deploy

    Hello Guys.
    I know Dynamic Proxy is the default when deploying EJBs starting from AS 8.1. If I want to use Dynamic Proxy in AS before 8.1, how can I do that?
    Thanks.
    Rye

    Just to clarify, I assume you're referring to the Remote EJB dynamic RMI-IIOP feature in 8.x and later.
    Java SE has a generic dynamic proxy facility in the java.lang.reflect package. That can of course
    be used by any JDK 1.4 program and has no relationship to Java EE.
    There is no support for the Remote EJB dynamic RMI-IIOP feature prior to AS 8.x / J2EE SDK 1.4.
    In those releases, e.g. S1AS 7.x / J2EE 1.3 SDK , static RMI-IIOP stubs are generated during
    deployment and must be present for any client access to Remote EJBs.
