Proxy Error When Invoking Web Service

Hi all,
i created a web service from a session bean,
when i invoke the web service from my web browser it works great,
but when i try to invoke it from a bpel process, i get the following error in the Invoke Activity:
when invoking endpointAddress 'http://10.0.1.159:8989/EJB-Application2-Model-context-root/updatePayloadServiceSoapHttpPort', (502)Proxy Error ( The ISA Server denied the specified Uniform Resource Locator (URL). )
any idea what to do to resolve this issue?
thanks

It seems that your proxy server refuses serve requests for your private network (10.0.x.x).
Try to turn off proxy server in your BPEL. In devel server turn off proxy (or add this address to exceptions) in <ORAHOME>\integration\orabpel\bin\obsetenv.bat
and if you are using full AS, go to EM a change parameters for these server properties:
-Dhttp.proxySet=true
-Dhttp.proxyHost=yourproxy
-Dhttp.proxyPort=proxyport
-Dhttp.nonProxyHosts=10.0.1.159|and rest of your exceptions

Connection Reset Error, When invoking Web Services

I'm trying to invoke a web service using 'Invoke Web Service' Operation. Its works for 8 out of 10 times. Sometime it stalled with "Conneciton Reset' error.
When retry this stalled action from AdminUI, its works fine.
Can someone advise on this issue?
I have attached the error log for reference.
Thanks,
Nith

If you attempt to retry the stalled component through adminui, it will work. Am i correct?
If so, you can test the following approach.
1. drag a blank component (e.g a decision point)
2. connect a line between the exception of the Web Service Invoke operation to the decision point.
3. Choose java.io.IOException from the eeception drop down.
4. again connect the decision point back to the web service invoke component. (i mean a looping)
This approach was working fine with me.
Please see the attached image shows my routing.
PS: After a couple of days, I tested without looping and it seems to be working. So I removed the loop now.
Thanks,

Java.sql.SQLException: Closed Connection error when invoking web service

Hi
I've assembled a simple web service for an Oracle PL/SQL package and deployed it on a Standalone OC4J, when I come to invoke it on the Oracle Enterprise Manager screen I'm getting the following returned within the envelope body:
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: java.sql.SQLException: java.sql.SQLException: Closed Connection)</faultstring>
</env:Fault>
</env:Body>
The function that is called within the database returns a user defined object that consists of a RAW value and an XMLTYPE. The function takes a string as a parameter, when I enter a string that I know will not return an object there is no error in the envelope body, only when there is an object to return does the error appear.
Anyone have any suggestion as to why this is?

I'm no further forward with this: has anyone assembled, deployed and invoked a web service that returns a XMLTYPE?? I know this should be possible but I think there's maybe some manual intervention required with the classes created with webservicesassembler: I'd really appreciate it if anyone with any experience of this kind of thing could help me think this through.

Jdeveloper WS proxy error while invoking web service deployed on weblogic

Hello experts, can you please help me. I have web service deployed on weblogic server.
I have not set any credential for this web service. I can test the service from SOAPUI without providing any credentials.
Then I generated WS proxy client using Jdeveloper. When I try to run the client, I do not know why I get security execption (shown below) eventhough I have not secured the web service deployed on weblogic server.
java.lang.SecurityException: keyStoreFilename is either null or empty string

// QueryPageInputSecondPage qpisp= new QueryPageInputSecondPage(); //I have commented it in order to resolve security issue
System.out.println("Inside the client class");
} catch (Exception ex) {
ex.printStackTrace();
Inside the method setPortCredentialProviderList(), I have not provided any credentials, keystores etc. Because weblogic is not setup with SSL and also I have not set up any authorization or authentication for the web service. I do not know why I am able to test it through SOAPUI and why not using WS proxy.
Appreciate your quick response.
thanks a lot

"Error while parsing SOAP XML payload: no element found" received when invoking Web Service

Running PB 12.1 Build 7000. Using Easysoap. Error ""Error while parsing SOAP XML payload: no element found" received when invoking Web Service". This error does not appear to be coming from the application code. Noticed that there were some erroneous characters showing up within the header portion of the XML ("&Quot;"). Not sure where these are coming from. When I do a find within the PB code for """" it gets located within two objects, whereas they both reference a "temp_xml_letter". Not sure where or what temp_xml_letter resides???   The developer of this is no longer with us and my exposure to WSDL and Web Services is rather limited. Need to get this resolved...please.

Maybe "extraneous" is an incorrect term. Apparantly, based upon the writeup within Wiki, the parser I am using does not interpret the """? How do I find which parser is being utilized and how to control it?
<<<
If the document is read by an XML parser that does not or cannot read external entities, then only the five built-in XML character entities (see above) can safely be used, although other entities may be used if they are declared in the internal DTD subset.
If the document is read by an XML parser that does read external entities, then the five built-in XML character entities can safely be used.

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

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
[Click here|http://en.wikipedia.org/wiki/List_of_HTTP_status_codes] to understand all HTTP code
I am closing this thread, if you have any question post new question in forum.

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

Error when creating web service client in netbeans

i tried to create a web service client from a wsdl and an error pops up:
web service client can not be created by jaxws:wsimport utility.
reason: com.sun.tools.xjc.api.schemacompiler.resetschema()v
There might be a problem during java artifacts creation: for example a name conflict in generated classes.
To detect the problem see also the error messages in output window.
You may be able to fix the problem in WSDL Customization dialog
(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).
end of error message
I am using netbeans 6.0 RC 2 and the bundled tomcat 6.0.13. Please help me.

Error while invoking web services from Proxy services in OSB

I have a Proxy Service of message type in Oracel Service Bus 10gR3 and it passes the incoming messages from a JMS Queue to Business Service of Web Services type. This Web Service is hosted in Glass Fish v3 and it's binding style is RPC. The JRE used in both the servers are 1.6.0_20. The JMS message is of Text type. The Web Services at the Glass Fish throws MessageCreationException for any content of the JMS message. However, it works fine if Business Service's test client is invoked from the OSB'S Admin Console. However, the same will not work if Proxy Service's test client is called.
The detailed exception stack is given below :

Let me explain what I am trying to achieve. Our application receives data from multiple sources - from mainframe using FTP, JMS Queue and BPM application using Web Services. The data from all these sources are sending to a Web Service running in GlassFish V3. To handle this I have created three Proxy Services and one Business Service on OSB. The Business Service is of type Web Service using the same WSDL from the target Web Service.
The Proxy Services are configured as follows:
Proxy 1 (type - Messaging service) listens to the JMS Queue and receives JMS Text Message -> Business Service(B1) (Web Service).
Proxy 2 (type - Messaging service Polls files from the FTP Server -> Business Service(B1) (Web Service).
Proxy 3 (type - Web service) is invoked by the BPM application and sends a String -> Business Service(B1) (Web Service).
All the Proxies route to the same Business Service - B1 which calls the Web Service in GlassFish. The only Proxy that works fine is Proxy 3 which is created using the same WSDL of the Web Service. In the other two proxies it thows the same exception in GlassFish as I mentioned before.
com.sun.xml.ws.protocol.soap.MessageCreationException: Couldn't create SOAP message due to exception: XML reader error: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog at [row,col {unknown-source}]: [1,0] at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:359)
Is this configuration correct to achieve my requirements?
Once again thanks for the help.

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 :
oracle.jdeveloper.webservices.tools.WsdlValidationException: Error creating model from wsdl "file:/C:/JDeveloper/mywork/ApplicationAppelServiceSCA/Model/src/model/common/AppModuleService.wsdl": 'unset' is already defined'Bytes' is already defined'ref' is already defined'Duration' is already defined'Types' is already defined'Character' is already defined'type' is already defined'Day' is already defined'nestedInterfaces' is already defined'Date' is already defined'datagraph' is already defined'Type' is already defined'Integer' is already defined'ModelsType' is already defined'ChangeSummaryType' is already defined'instanceClass' is already defined'Month' is already defined'DataObject' is already defined'javaClass' is already defined'LongObject' is already defined'DateTime' is already defined'dataObject' is already defined'YearMonth' is already defined'ShortObject' is already defined'Long' is already defined'types' is already defined'JavaInfo' is already defined'IntObject' is already defined'Boolean' is already defined'DoubleObject' is already defi...
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....

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.
