Please let me what mistake i am doing if any? or is this a bug
Thanks

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 com.sun.xml.ws.client.sei.SEIStub.invoke(SEIStub.java:118)
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 class from a Class instead of an Interface

Why is not possible to create a dynamic proxy class from a Class instead of an Interface, using java.lang.reflect.Proxy?
I have seen the source code of Proxy :
     * Verify that the Class object actually represents an
     * interface.
     if (!interfaceClass.isInterface()) {
          throw new IllegalArgumentException(
          interfaceClass.getName() + " is not an interface");
It seems to be restricted as a desing desition. Has someone knows about the reason of that?
There is a workarround for creating dynamic proxy classes from any POJO which not implements any interface?

The JDK doesn't allow you to proxy classes for a few reasons: it encourages you to use interfaces - often a good idea - and also, proxying of classes exposes you to unpredictable behaviour. Since dynamic proxies are created by generating a new class at runtime, if you proxied a class you'd be generating a subclass of that class, and if the superclass had any final methods, the proxy wouldn't be able to intercept invocation of them, so your proxy wouldn't work properly. Also, the superclass would actually be loaded, which could produce other unpredictable results if, say, that class had a static initializer. With an interfaces, you generate an object that just has the public API described by the interface, with a class, you're actually generating a subclass of the proxied type, which isn't the same thing
If you really want to proxy a class rather than an interface, there are various third-party libraries around that will do it for you. ASM, CGLIB, BCEL to name a few. My choice would be ASM, but really I'd urge you to try and re-design with interfaces if at all possible

Using Dynamic Configuration api for SOAP adapter

I want to use Dynamic Configuration api to send a SOAP request to a webservice.
tha value in my adapter is
my Target URL is
http://xidr3.bcs.de:50000/XISOAPAdapter/MessageServlet? channel=:Routing2_Service:SS_SOAP_Sender_Working_June12&nosoap=true
which is the corresponding field i have to set in Dynamic Configuration?
I have written the following code is this right?
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
String temp = "http:/"+"/sap.com/xi/XI/System/SOAP";
DynamicConfigurationKey key = DynamicConfigurationKey.create(temp, "TServerLocation");
String varURL =
"http:/"+"/xidr3.bcs.de:50000/XISOAPAdapter/MessageServlet?channel=:Routing2_Service:SS_SOAP_Sender_Working_June12&nosoap=true";
conf.put(key,varURL);
return "";

Hi,
Yes, your code looks fine. Can you let me know what is the error you are getting. Have you checked the Flag in your communication channel.
Use Adapter-Specific Message Attributes
Variable Transport Binding
Once you test your scenario you can see the Dynamic URL in your message Header by going to tcode sxmb_moni. See if you are able to find something called DynamicConfiguration in your message haeader. If yes what is the value set there.
PS: From the target URL you posted It looks like your webservice is hosted on the XI box itself. Is it the same XI box or different box? Just curious to know.
Reward point if answer is helpful

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?

Any example of dynamic proxy with RMI?

Hi, are there any good example of dynamic proxy with RMI, using the new RemoteObjectInvocationHandler class?
I am currently implementing a Registry, and want to use dynamic proxy to wrap around the registry stub, to pass extra information to the client.
I've tried it, but the program will hang and get this exception:
Exception in thread "RMI TCP Connection(1616)-192.168.1.23" java.lang.OutOfMemoryError: Java heap space
My implementation looks like this:
public RegistryImpl extends RemoteServer Implements Registry {
    public RegistryImpl(int port, Properties... properties) throws RemoteException, ChannelException {
         // Create a reference for the registry.
     LiveRef liveref = new LiveRef(id, port);
        ref = new UnicastServerRef(liveref);
         Registry proxy = (Registry)RegistryProxy.newProxyInstance(
              this.getClass().getClassLoader(),
              this.getClass().getInterfaces(),
              new RemoteObjectInvocationHandler(this.getRef()));
         /* Using dynamic proxy */
         usref.exportObject(proxy, null, true);
public class RegistryProxy extends Proxy implements Registry {
     private InvocationHandler handler;
     public RegistryProxy(InvocationHandler handler) {
          super(handler);
          this.handler = handler;
     public Remote lookup(String name) throws RemoteException, NotBoundException, AccessException {
          Remote result;
          try {
               Method m = Registry.class.getMethod("lookup", new Class[]{String.class});
               result = (Remote)handler.invoke(this, m, new Object[]{name});
          } catch (SecurityException e) {
               throw new UndeclaredThrowableException(e);
          } catch (NoSuchMethodException e) {
               throw new UndeclaredThrowableException(e);
          } catch (Throwable e) {
               throw new UndeclaredThrowableException(e);
          return result;
     public void bind(String name, Remote remoteObj) throws RemoteException, AlreadyBoundException, AccessException {
     public void unbind(String name) throws RemoteException, NotBoundException, AccessException {
     public void rebind(String name, Remote remoteObj) throws RemoteException, AccessException {
     public String[] list() throws RemoteException, AccessException {
}I am new to Java programming, any help is appriciated.

Hi Eddie,
Perhaps you might like this one:

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

thnx kwalsh1 i got it working. It was the targets.xml file in jaxrpc/common, i edited the package-dynamic to include all class files!

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:

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?
