OC4J SOAP Question

Question

I am working on a new service provider and thinking to write it in Java and put it into the OC4J. I have successfully deployed a simple program which can take a string as the input value and sent it over http/SOAP and then return another string as the out put. The SOAP request is like:
<?xml version = '1.0' encoding = 'UTF-8'?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:getEmpSalary xmlns:ns1="EmpService" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<empNo xsi:type="xsd:string" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">asdf</empNo>
</ns1:getEmpSalary>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
In this case, I know that my Java program need to have a method call getEmpSalary and it will take a String input.
The new service I am working on will typically send me the SOAP request like:
<?xml version = '1.0' encoding = 'UTF-8'?>
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap-env:Body>
<batchRequest xmlns="urn:oasis:names:tc:XXX:2:0:core">
<smallRequest namevalue1 inputA="someValueA" inputB="someValueB" inputC="someValueC" inputD="someValueD" inputE="someValueE">
<somethingElse>
<present name="someName"/>
</somethingElse>
</smallRequest>
<smallRequest namevalue2 inputA="someValueA" inputB="someValueB" inputC="someValueC" inputD="someValueD" inputE="someValueE">
<somethingElse>
<present name="someName"/>
</somethingElse>
</smallRequest>
</batchRequest>
</soap-env:Body>
</soap-env:Envelope>
My questions are:
What's the name of the Java method I should implement for this particular request? searchRequest? What will be the types of input parameters? How can we handle the "somethingElse" item? Note that it's a grouped request with two smallRequests in it.
I am very new to this field and would really appreciate the help, or if you could just indicate some pointers.
Thanks for the help.

Answer 1

First question: What is the main difference between OC4J
WebServices and WebServices using Apache SOAP 2.2?
Answer:OC4J Web Service is much more scalable than Apache
SOAP2.2 and is in tune with JSR 109 which is going to be part of
J2EE 1.4.
Second question: Is the OC4J style going to replace Apache
SOAP2.2?
Answer:Our direction is OC4J Web Services but we also support
for Apache SOAP 2.2 for backward compatibility. Jdeveloper has
option for deploying to either.
Third question: (How) Is the Oracle XDK (going to be) used OC4J
WebServices and/or Apache SOAP2.2?
Question regarding How-To document:
I've deployed the HelloWS (stateless) pure Java Web Service in
OC4J 9.0.2.0.0 and I can access it's home page. There I can make
a selection for either WSDL, proxy jar or proxy source. If I
select to output the WSDL: http://..../hellows/helloService?wsdl
the webservice returns a internal server error 500, indicating a
NullPointer exception. Analyzing the stacktrace shows me that
the error occurs at or due to:
oracle.xml.jaxp.JXSAXTransformerFactory.getAssociatedStylesheet
(JXSAXTransformerFactory.java:424). The NullpointerException
occurs at oracle.xml.parser.v2.DOMLocator.getSystemId
(DOMLocator.java:104).
Any clues to what I'm missing here? Remember the proxy_jar and
proxy_soruce both return without error.
Answer:I actually I have it running on without any errors. I
can&#8217;t think of any problems other than Jdk issues. The certified
JDK is 1.3
