Internal error when downloading web service proxy jars

Hi,
I have a web service created from a stateless Java class in OC4J 10.1.2. I access the web page of the service and can download the WSDL and test the services, but if I try to download the compiled or source JAR files of the client proxy I get this:
500 Internal Server Error
java.lang.NullPointerException at oracle.wsdl.toolkit.util.JarUtil.addFileEntry(JarUtil.java:105) at oracle.wsdl.toolkit.util.JarUtil.createJar(JarUtil.java:34) at oracle.j2ee.ws.BaseWebService.generateClientStubJar(BaseWebService.java:1555) at oracle.j2ee.ws.BaseWebService.doGetClientJar(BaseWebService.java:1469) at oracle.j2ee.ws.BaseWebService.doGet(BaseWebService.java:1142) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
I ccan find both the java and class files at %OC$J_HOME%\j2ee\home\application-deployments\myapp\myapp2006\temp\__java_stateless_rpc...(packages)...\proxy
So I have the impression that the problem comes at packaging files into a JAR file.
I've noticed the class names are very long because they include the full package route changing dots for underscores, which in my case results in class names of up to 64 characters (excluding extension and separator dot). Also the proxy directory where those files are created is very deep because after the __java_stateless_rpc directory the full package structure is repeated twice. I've detected that Windows Explorer does not allow me to delete, edit or view properties of those class and source files with names of 64 characters or more under the proxy directory, which for those cases means a complete path of over 256 characters.
I'm not sure if this is the cause, but anyway I don't like those very long class names, is there any way of instructing the servlet to use other name generation scheme?
Regards

Hi,
It seem that I was right and the length of the paths where in the heart of the problem. I've moved my oc4j directory to the root of my filesystem and the problem has dissapeared.
Anyway, I find that name scheme very ugly and also ackward to use in the client, I could probably edit the sources myself but having to do so each time something changes...
I'd propose that the servlett replicated the package structure under which the beans are originally, thus creating a more natural and logical structure with much shorter names.
Maybe the path under __java_stateless_rpc could also be shortened.
Regards

Error when generating Web Services Proxy for SCA Application Module

Hello,
I'm trying to create Web Services for a simple Application Module with JDeveloper 11g (11.1.1.3.0).
I start a new ADF Project, I create an Application Module as simple as possible : it contains only a simple View Object on the DEPT Entity.
On my Application Module, I choose "Service Interface" and I add my View Object in the service interface.
I test my Web Service in the Embedded Weblogic Server, it works well. (I succeed in using the Get operation, for example).
But when I try to generate a Web Service proxy (right-click on the WSDL File -> Generate Web Service Proxy), It always fail with such errors :

Can someone help me to understand this error ?
i never manually edited the WSDL File, so I don't understand why the generated WSDL or XSD files might contain errors.
Thanks for your Help,
Laurent

We have the same problem, and the problem was in the xsd import:
The wdsl import a schema that import other schema, the second import use a relative path, that was wrong.
So check the xsd import sequence....

Hi Yatan
The error is mostly there may be some Duplicate variable/schema element decalared in the wsdl or the xsd referred in the wsdl. Like in WSDL for any Operations, most of the times, we use input and outputs as complex xsd element. We declare these xsd in the same file or in another file and import that in the .wsdl file. So check or validate your XSD file for any Duplicates.
In JDeveloper itself, I think, you can open XSD or WSDL and validate it from right click menu options like that.
Thanks

Compile error when using Web Services Proxy

I used the wizard and kept all default settings then I edited the <Port>.java class to make the actual invocation.
When I tried to compile the generated code I got 2 errors in the FaultMessage class about 2 missing Constructors:
Error(17,5): cannot find constructor Exception(java.lang.String)
Error(25,5): cannot find constructor Exception(java.lang.String,java.lang.Throwable)
Looking at the class hierarchy I noticed that FaultMessage extends from a Exception class which was generated by the Wizard so I decided to add the constructors there.
Once the .ctors are created it works as expected.
I'm posting this message anyway so it helps others if facing the same issue and to raise the question about why is this happening? Perhaps some wrong jars in my system? Aren't Jdeveloper generated classes supposed to work 'out of the box'?
Thanks,
MV

Error when calling Web Service in SAP Netweaver side.

An error occurred while trying to make a request to URI 'http://us4184.wdf.sap.corp:1080/sap/bc/srt/wsdl/sdef_WS_SSC_USR_GET_USER_LIST/wsdl11/ws_policy/document?sap-client=000'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.
Does anybody know where can I put the cross-domain policy in Netweaver platform?
Best regards,
Anders

Hi Anders,
The resolution of the crossdomain problem is not to store an cross-domain-policy file at the [SAP] webservice side; but instead it needs to be done at the (every...) webservice client. In case the client is an IIS based webapplication (and thus the ultimate end-users are accessing it via their browser), this is not such an issue. It there is sufficient to put an crossdomain.xml policy file in the IIS main virtual root of your 'client' .net webapplication (c:\inetpub\wwwroot). It also can be required or at least helpful to put a clientaccesspolicy.xml file; both at the main virtual root and in the virtual root of the specific webapplication
In case of SharePoint application, the crossdomain.xml file must be stored in the WSS virtual root of that site; c:\inetpub\wwwroot\wss\virtualdirectories\<your SharePoint webapp>
Best regards, William.

Validation error while creating Web Service Proxy.

Hi,
I'm trying to create Web Service Proxy. But I'm stuck with a Validation error
model error: type
+"{http://xmlns.oracle.com/2001/XMLSchema/DOM}+
+org.w3c.dom.Document" not found.+
I'm using "Create Web Service Proxy" wizard. There are 6 steps in creating proxy through JDev. wizard.
First step itself displaying the above validation error when I click on "Next" button.
Few points
We have created web service using "oracle.j2ee.ws.StatelessJavaRpcWebService" servlet
Thanks in advance.

Hi,
It might be that the .net service which you have is not WS-I compliant. Can you first run WS-I Analyzer on the wsdl to see it the test passes.
Thanks,

Serialization error when calling web service method

Hi,
In JDeveloper 10.1.3.1, I'm working on an EJB that will be deployed as a web service. There is a method in the EJB that is defined to return a generic Object, but in the implementation, it really returns one of several possible specialized bean objects. I can deploy the EJB successfully to IAS 10.1.3.1.
I created a web service proxy from the wsdl that was generated from deploying the EJB. Using the proxy, I try to call the EJB method and cast the method's return value to the bean object I know should be returned. However, I get an error like this:
java.rmi.ServerException:
start fault message:
Internal Server Error (serialization error: no serializer is registered for (class com.test.TestBean, null))
:end fault message
Does anyone know how this serialization error can be resolved? If I change the web service method signature to return the bean object that is actually being returned (instead of Object), then it works fine. But I want to be able to define the method to return a generic Object because I plan to make the method flexible enough to return several different types of bean objects. Whenever the client calls the method, it will know what is the actual object being returned and I had planned to cast the return value to its actual class.
Thanks for any ideas.

Well, I think so... I've followed all the steps, and my merged WSDL file seems like the one in page 12...
Any suggestion, please?
Thank you,

Gracefully throwing a error when the web service is down

Guys,
I have web service calls in my application. (through web service data control).
My Appliacation throws exception when the web service is down. i want to my application to throw some meaningful error on the UI.
How this can be acheived?

Hi,
you can use a custom error handler defined in the DataBindings.cpx file or use a declarative exception handler in ADF Controller

Validation Failed when creating Web Service Proxy

Hi
I am having trouble creating a web service proxy in JDeveloper (11.1.1.3). When I enter the endpoint URL (which is a https WSDL file). I get the following error:
No WSDL document could be found at https://host:port/.../.././...wsdl.
I can open the WSDL in SOAP UI and it accesses it fine and I can call the service within.
When I put it in a browser I need to enter the authentication details before I can view the WSDL.
But I can't get to the next step in the Web Service Proxy wizard, I've had a look in the threads before an couldn't find any help.
Is there anyone who can help me with this?
Regards
Saheem

Thanks John but unfortunatly that didn't help.
I removed the proxy but the WSDL was still not found I also added the host to the Proxy exceptions list and switched the proxy back on but this did not work either.
I also tried the method in the link you provided. But I get an error when attempting to create a Web Service Dasta Control too. The error I get here is:

Error when processing web service call

Hello Experts,
Based on a requirement, I got a URL based on WSDL, using which I created a Consumer Proxy in SAP.
I created a Logical Port in SOA Manager with type selected as 'WSDL', and didnot gave any authentication id or password in it.
When I'm trying to execute the proxy class to call the webservice using the logical port, it is asking me a prompt for Userid and Password, and when I press enter, it is throwing an error log as stated below.
SOAP:1,007 SRT: Unsupported xstream found: ("HTTP Code 401 : Unauthorized")
(Error when calling SOAP Runtime functions).
I think I configured the Logical port incorrectly. Is there any specific setting that I missed, I dont know.
Kindly help me out.
Thanks,
Mallik

Unsupported xstream found: ("HTTP Code 401 : Unauthorized")
Unsupported xstream means response received from service provider (host) is NOT in valid xml format (usually HTML). You will see this type of error when host or service you are trying to call return HTML (error pages etc).
HTTP Code 401 : Unauthorized : Clearly means that user/password for service provider is incorrect

(Edit Web Service Attributes action)
or by manual editing of the local wsdl or schema files, using the JAXB customization
(local wsdl and schema files are located in xml-resources directory).

I am using netbeans 6.0 RC 2 and the bundled tomcat 6.0.13. Please help me.

Hi Yatan
The error is mostly there may be some Duplicate variable/schema element decalared in the wsdl or the xsd referred in the wsdl. Like in WSDL for any Operations, most of the times, we use input and outputs as complex xsd element. We declare these xsd in the same file or in another file and import that in the .wsdl file. So check or validate your XSD file for any Duplicates.
In JDeveloper itself, I think, you can open XSD or WSDL and validate it from right click menu options like that.
Thanks
