Starting developing web services with Apache CXF
My first question here :)
So I'm assigned a web-service based task but unfortunately I don't know
almost anything about web services ! After some searching I decided to use
Apache CXF but I'm facing some trouble.
I do not need an interface so I only wrote a simple implemented class just
to get things started
----------------------------------------------------------------------------------------------------------------------------
package com.sc.ipk.ws.services;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.xml.ws.BindingType;
import javax.xml.ws.soap.SOAPBinding;
@WebService(serviceName = "calcServiceName", portName = "calcPortName")
@BindingType(SOAPBinding.SOAP12HTTP_BINDING)
public class Calculator {
/**
* @param firstOperand
* @param secondOperand
* @return The sum
* @throws AddNumbersException
* if any of the numbers to be added is negative.
*/
@WebMethod
public int addition(@WebParam(name = "firstOperand") int int1,
@WebParam(name = "secondOperand") int int2) {
return int1 + int2;
}
@PostConstruct
@WebMethod(exclude = true)
public void willResponse() {
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>> Will response");
}
@PreDestroy
@WebMethod(exclude = true)
public void doneResponding() {
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>> Responded");
}
}
----------------------------------------------------------------------------------------------------------------------------
This is my ant java task to produce client, server and wsdl files:
----------------------------------------------------------------------------------------------------------------------------
<java classname="org.apache.cxf.tools.java2ws.JavaToWS" fork="true">
<arg value="-soap12" />
<arg value="-wsdl" />
<arg value="-server" />
<arg value="-client" />
<arg value="-verbose" />
<arg value="-o" />
<arg value="IpkWS.wsdl" />
<arg value="-databinding" />
<arg value="aegis" />
<arg value="-portname" />
<arg value="IxAccess" />
<arg value="-address" />
<arg value="http://localhost:8080/ipk-ws" />
<arg value="-servicename" />
<arg value="IpkWS" />
<arg value="-frontend" />
<arg value="jaxws" />
<!--
<arg value="-s" />
<arg value="src" />
-->
<arg value="-d" />
<arg value="webapp/WEB-INF/wsdl" />
<arg value="com.sc.ipk.ws.services.Calculator" />
<classpath>
<path refid="cxf.classpath" />
</classpath>
</java>
----------------------------------------------------------------------------------------------------------------------------
I use ant because It's much easier for, I'm *terrible* with maven.
Here is what I need to do:
- I need to publish this service so a *.net* client is able to consume it,
that's why I need to use aegis. Unfortunately the *.net* client isn't
accessible now for raid testing but I guess the generated java client code
should get me half way through
Now I'm facing the following issues:
- @WebParam isn't effective, when I use it, i get parsing errors that the
expected elements are "firstOperand" and "secondOperand", this is the error
stack:
Exception in thread "main" javax.xml.ws.soap.SOAPFaultException:

- After succeeding with that, I need to package my service as a *war* file
and deploy it into tomcat 7 and expose a servlet context parameter from
another web app on the same servlet container of course, so how can that be
done !
- Another issue is that the generated client code is generated as if the
soap binding is *1.1* while I declared explicitly in the service
implementation class that the soap binding should be *1.2*
QName serviceName = new QName("http://services.ws.ipk.sc.com/", "IpkWS");
QName portName = new QName("http://services.ws.ipk.sc.com/", "IxAccess");
Service service = Service.create(serviceName);
service.addPort(portName, *SOAPBinding.SOAP11HTTP_BINDING*, "
http://localhost:8080/ipk-ws");
com.sc.ipk.ws.services.Calculator_PortType client =
service.getPort(portName, com.sc.ipk.ws.services.Calculator_PortType.class);
I'm using Apache CXF v2.7.3 and I included these jars in my classpath:
commons-logging-1.1.1.jar
httpasyncclient-4.0-beta3.jar
httpclient-4.2.1.jar
httpcore-4.2.2.jar
httpcore-nio-4.2.2.jar

spring-web-3.0.7.RELEASE.jar
wsdl4j-1.6.2.jar

Along with other JARS of course for other applications but these are
obviously the ones CXF needs, unless I messed something up !
Please don't hesitate to reply if I failed to clarify anything and thank
you in advance for your time.
Re: Starting developing web services with Apache CXF
Posted by Muhammad Gelbana <m....@gmail.com>.
Thank you for your very fast reply :)
When I used SoapUI to test the service while its deployed, (Instead of the
generated client\server classes), everything worked as expected. The
generated classes must have needed extra tuning from me, I think !
Thanks a lot for that great link !

Links #2 (preferably) or #3 should take care of you here:
http://www.jroller.com/gmazza/entry/blog_article_index , link #55 for
the SOAP 1.1/1.2 issue. Link #2 serves equally well as a Maven tutorial.
