OOW Demo3 - .NET/J2EE interop by examples

Last week, I have been presenting at Oracle Open World on the subject of Web services interoperability between .NET and J2EE, with a focus on Oracle's implementation of JAX-RPC that is available in our latest developer preview.

Today, I have a very simple example of 'tweaking a local copy of the original WSDL'.

Here is the WSDL : http://www.tilisoft.com/ws/LocInfo/ZipCode.asmx?WSDL

C:\ow2005\Demo3>java -jar /oc4j/webservices/lib/wsa.jar genProxy output ./gen_src wsdl http://www.tilisoft.com/ws/LocInfo/ZipCode.asmx?WSDL
SEVERE: WSDL validation failed. The wsdl contains a mixture of styles - "document" and "rpc". Only "rpc" OR "document" is supported in a wsdl, not both.

work around:
- make a local copy
- edit the WSDL, and replace the instances of rpc with document.
- re-run the genProxy command

For some reason, the publisher of this service has been using 'rpc' at the service level, then 'document' at the operation level (or method level in C#).
<wsdl:binding name="ZipCodeSoap" type="tns:ZipCodeSoap">
  <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc" />
  <wsdl:operation name="GetDistance">
    <soap:operation soapAction="http://www.tilisoft.com/ws/LocInfo/GetDistance" style="document" />

There is just one line to modify to get going.
  <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" />

Done deal, you can generate the code with the local copy.

C:\ow2005\Demo3>java -jar /oc4j/webservices/lib/wsa.jar genProxy output ./gen_src wsdl ./etc/ZipCodeV2.wsdl

To test the generated code, edit
C:\ow2005\Demo3\gen_src\com\tilisoft\www\locinfo\ZipCodeSoapClient.java

Just add those 3 lines to the main method:
    // Add your own code here
    Element res = (Element)myPort.getInfo("94403");

    System.out.println("info for 94403 :");
    ((XMLElement)res).print(System.out);

The output will be looking like this (truncated for preserving space here) :
     [java] calling http://www.tilisoft.com/ws/LocInfo/ZipCode.asmx
     [java] info for 94403 :
     [java] <GetInfoResult xmlns="http://www.tilisoft.com/ws/LocInfo/literalTypes">
...


Now, you have access to the raw data from the ADO.NET dataset, and you can start to write your own XSLT to extract the data.

Changing the version of JDK used by JDeveloper

I have recently learned a quick and lazy way to change the version of the JDK used to run JDeveloper 10g R3. I am sure there is an option somewhere in the configuration screen to do the same, which I couldn't find... While JDeveloper is not running, locate the embedded JDK on disk and rename (or delete) that directory. For me, it was C:\opt\jdev\jdk. Once it's done, restart and you will by asked to locate the version of the JDK you want to use. It's another step to get going with JAVA on Vista. -ecco

Connection reset from a WCF Web Service

Here is an error message you may see, when calling WCF Web Services from java: IOException retrieving the response: java.net.SocketException: Connection reset As it may not be obvious the first time you see it, this may save you some time. One reason for this behaviour is when the WCF endpint is expecting to see wsa:Action SOAP header in the request. To find out if you are facing this case, you have to look inside the WSDL, and search for the policy that describes the contract for your endpoint. <wsp:Policy wsu:Id="CustomBinding_Echo1_policy">   <wsp:ExactlyOne>     <wsp:All>       <wsaw:UsingAddressing/>     </wsp:All>   </wsp:ExactlyOne> </wsp:Policy> To make this a concrete example, here is a sample WSDL . To find the policy, you will need to follow the import as the policy are not always advertized in the top-level document. Here is how the import looks:   <wsdl:import namespace="http://example.org/" location="h

unexpected null value for literal data

There is a challenge that is hard to overcome at first; making sense of error messages. You can always Google with the text of the error, “unexpected null value for literal data” and hope to be lucky . If you are using Oracle Application Server 10.1.3.0, here is the explaination for the message and two ways out. The Exception: unexpected null value for literal data at oracle.j2ee.ws.common.util.exception.JAXRPCExceptionBase.<init>(JAXRPCExceptionBase.java:52) at oracle.j2ee.ws.common.encoding.SerializationException.<init>(SerializationException.java:26) ... The relevant schema: <complexType name="Customer"> <sequence> <element name="address" type="tns:Address"/> <element name="firstName" type="string"/> <element name="lastName" type="string"/> </sequence> </complexType> A sample code that will cause this exception: public void testServ() throw
