Problem while invoking a web service within an XML native database

Within the eXist dbms, I'm writing a module which implements several extensions to XPath. These extensions must invoke a remote web-service.
I initially tested a standalone consumer, and everythink worked out successfully. Thus I created a jar, I used the same code in eXist, recompiled it, and started the server. I thus launched an XPath query (containing these extensions), and I received the following exception:
Provider com.sun.xml.ws.spi.ProviderImpl not found
What does it mean?
What am I missing?
CLASSPATH should be ok, since it is set to (and it is the same of the "standard" consumer):

Problems while invoking a web service

Hi everybody,
I need to call a web service and treat its response data. So I'm using OdiInvokeWebService tool, and trying to export the response to an xml file, in order to be able to treat the information. The question is that I just can't get the response, because the response file is empty after doing the call. If I try with the "advanced" option of the tool, the result is the same, doesn't matter which mode of request (xml request or xml file request) I use. But I'm even more worried considering that the process works properly when I use a tool like soapUI, that means, I get a result when I call the web service with this tool. It looks very strange because I used ODI previously with the same goal, and I didn't have any problem working in the same way. So, could somebody help me with this issue?
Thanks in advance,
Hibai.

> The problem is, when my application running in Netweaver tries to consume the webservice, it takes the external access to try to reach the webservice URL instead of take the VPN route to do that. ie. my application find an external IP of the webservice instead of finding the internal IP.
You're using a proxy?

Using SAML policy while invoking a web service

I have to invoke a webservice which is secured using the policy wss10_saml_token_client_policy.
In order to achieve the above i have creates a stub using JAX-WS and while invoking the web service I pass the policy as a SecurityFeature.Code snippet given below:
SecurityPolicyFeature[] securityFeatures = new SecurityPolicyFeature[] { new SecurityPolicyFeature(
getValueFromPropertyFile("oracle/wss10_saml_token_client_policy"))};
SomeStub stub =(UserManagementPortTypev1_0)SomeService.getPort("...","....",securityFeatures );
Once deployed in weblogic and when i invoke the service, the soap request formed is correct. It creates for me the soap header with the correct security nodes. The header formed is like below:
<S:Header>

The node NameIdentifier is supposed to be populated with the logged in user id, which will be picked up from JAAS principal.
Now I am invoking the service hosted in weblogic from outside using JSON protocol, I do not have a portal ready to invoke the service.
My question is, is there any way in which i can replicate/ simulate the JAAS principal such that the nameidentifier is populated even when invoked from outside. THis is a requirement from testing perspective.

Hi,
Thanx it is working now.
BTW can you give me some urls with info of this kind of setting which i need to do for other kind of integarions in J2EE platform.Sorry if i am asking too much as i am a starter in this technology.

Problem while Introspecting a Web-Service in OBPM 10GR3 studio

I get the following problem while Introspecting a Web-Service in OBPM 10GR3 studio:-
Introspecting...
downloading /test-ws/testc?wsdl [Error] Instrospection exception: Web Service WSDL parse exception: HTTPS hostname wrong: should be <test-01.test.net>...
Any idea why?
It runs well in a browser, eclipse and SOAP UI?

have you create the destination?
do you use the wizard to generate code?
usually there is catch clause for this line of code
wdContext.currentRequest_SERVICE_MDM_LOOKUPElement().modelObject().execute();

Error invoking a web service within another web service

Hi all!
I have to develop a web service which needs to invoke another web service, thus the first web service is acting as a client of the second one. To get this, the first web service uses the proxy provided by the home page of the second one. However, when the first service invokes the second service, the body within the soap message is modified in such a way that it is not valid for the second service, because some namespaces declarations are added, in spite of the fact that they already exist. Then, I find the following:
Body of the SOAP request created by the first web service:
<a:request attribute1="urn:attribute:one"
xmlns:a="urn:namespace:one" xmlns:b="urn:namespace:two">
<b:body>Hello</b:body>
</a:request>
Body of the SOAP request received by the second web service:
<a:request xmlns:a="urn:namespace:one"
attribute1="urn:attribute:one"
xmlns:a="urn:namespace:one" xmlns:b="urn:namespace:two">
<b:body xmlns:b="urn:namespace:two">Hello</b:body>
</a:request>
I have also tried to run a client using this proxy outside the web service, and everything is ok. So, from my point of view, the problem is when running the proxy inside a web service. I wonder if I have to do something special with this proxy in order to use it within a web service.
Has anybody run into this situation?
Could anybody be so kind as to tell me how to solve it or if, on the contrary, it is an oc4j bug, please?
Thank you very much in advance.
Inma.

Extra Tag Getting Added while invoking a Web service

Hi all,
We are facing an issue while trying to invoke a web service. We are assigning values to invoke input variable of the invoke. The issue is that while invoking an Extra element named “input” is getting added.
For Eg: The required one is
<messages>
<invoke_Webservice_Input>
Payload
</invoke_Webservice_Input>
</messages>
But what is getting passed is :
<messages>
*<input>*
<invoke_Webservice_Input>
Payload
</invoke_Webservice_Input>
*</input>*
</messages>
Due to this, the invoke is failing and we are not able to proceed. The error which we are getting is "*exception on JaxRpc invoke: unexpected null*"
If any has faced similar issues, please share your experience.
PS: The same wsdl is working in other environments. only thing we changed is the Endpoint URI and that endpoint URI is also accessible.
Thanks
Mohan

can u re import the wsdl into the process and then change the endpoint uri... undeploy the previous process.. bounce the server and then deploy the new process and try

User Name and Password in weblogic realm while invoking a web service

Hi,
I deployed a rpc web service using WLS 7.0 SP2 in HP-UX 11 environment. When I
invoke the web service through my browser (IE 6.0) using the web services url,
it brings my service method correctly. From there, if I click the invoke button
it asks me for a network user name and password under "weblogic" realm??? If I
provide the admin user credentials (which I supplied while creating my domain)
it is not accepting that it keeps popping up this network user password window
over and over. Not sure which username/password I have to provide here to see
the result of my service.
If I try to invoke the web service through my client (static) I am getting a connection
refused exception. I guess either way, I am not able to access my web service.
In the attached file, I have cut and pasted the client stack trace as well as
the server log trace from weblogic.
Any ideas would be highly appreciated.
Thanks,
Ganesh
[errorstacktrace.txt]

I think the client is not able to do a HTTP POST
to the WLS server but it can do a HTTP GET.
I dont know why.

Unexpected element name: expected error while invoking external web service

Hi,
In JDeveloper when I invoke external web service call, I am getting following exception
"unexpected element name: expected=..."
But the same application works fine in .NET. Can someone help me as to why I am getting the exception only in JDeveloper and how to fix this exception.
Thanks.

Hi,
Without more information, it will be hard to help, and tell you what could be teh issue.
Usually, this kind of error occurs when the payload and the WSDL schema are out of sync, for example if the order of the element on the wire do not match the order in a sequence declaration, you may get this error.
In such case, .NET handle the XML as if it was a 'all' -- no specific order -- and deserialize the message properly.
Hope this helps,

Problems while consuming a web-service through Netweaver using VPN

Hi all
I'm facing a problem while I'm attempting to consume a .NET web-service that is located in a remote server. We've estabished a VPN connection between our Netweaver CE in Linux to the remote office where the web-service is running.
The problem is, when my application running in Netweaver tries to consume the webservice, it takes the external access to try to reach the webservice URL instead of take the VPN route to do that. ie. my application find an external IP of the webservice instead of finding the internal IP.
When I ping the webservice URL in linux, it brings me the internal IP, but for some unknown reason, the Netweaver don't find the correct route to reach the webservice.
Does anyone have any idea or suggestion on what to do?
Thanks in advance!

Error while invoking a Web service deployed on OC4J from Oracle BPEL

Hi,
I had created a web service from a simple java class using JDeveloper and deployed that on OC4J which had emmited a wsdl for the web service. On the same AS my BPEL processing is deployed in which i had created a partner link by using 1st option (i.e Browse WSDL files from local file system) and invoking the published method of the java class.I am expecting that the method of the class which is deployed as web service will be executed and i will get the return of the method as the response of the invoke activity , but i am getting this error :
<remoteFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="summary">

It seems that the Invoke activity is not able to get the WebService and it is asking for some settings , if any clue regarding this pls reply.
I can also give the wsdl also.

Error while invoking secure web service.

Hi,
I am trying to access a secure web service through a simple BPEL process in SOA Suite 11g. When I test it through enterprise manager I am getting the following error. Since it's a secured websecure i set the WS policy(oracle/wss_username_token_client_policy) in the external reference and also provided the credentials. If anyone has come across similar error or know the solution please let me know. Also I am not sure if its related to security or is it with the way I am trying to call the service.

Thanks very much for your suggestion. I will take a look into the wsdl again and see if something is wrong in that.
I have a peculiar problem with the wsdl. When I created the partner link using the remote wsdl it would throw a compilation error. But when I took a local copy of the remote wsdl and seperated all the schema's from the wsdl and imported them inside wsdl it gets compiled. But I am not sure if this is a appropriate thing to do and if that is creating this problem. Any thoughts on this would be really helpful.
