XML Parsing is done in Java based applications by a JAXP compliant Parser. The first Parser in the classpath sequence of jars wins and is used by all java classes of a application. Default for OC4J is to provide the Oracle XML Parser, which is a bit old. The solution is to force OC4J to use my JAXP Parser instead of the container Default Parser defined in the shared libraries.

My CXF Web Project is maven based. First thing to do is to add a new maven dependency to xerces 2.9.1 as JAXP Parser to use for CXF.

		
			apache-xerces
			xercesImpl
			2.9.1
			jar
			compile
		

So create with ‘mvn package’ a war file in the target directory.

I removed the CXF Application from the OC4J Container inside the servers view in eclipse and start the OC4J server. Now log in the admin web console with

http://localhost:8888/em/console/ias/oc4j/home

Go to Applications and click on the deploy button. Select on the first screen the WAR file as local archive location. Enter on the second screen a application name and change the context path to your needs. Click on the third screen on the link to change your class loading. Remove all imported shared libraries and click on the checkbox below for “Search first locally for classes”. Click ok to go back to the third screen and click on deploy to start progress. Now it will successfully start the Application and you can see e.g. all deployed webservices with

http://localhost:8888/cxf-sample/

Keep in mind to adopt the context path “cxf-sample” of the url to your needs.

So the libs are defined but nothing happened in eclipse. I use the M2 Eclipse plugin. Now i enable maven with right click on the project and choose from M2 the “Enable dependency management” entry. The plugin now download the libs into the local repository for all projects. In the eclipse build path you will find now a new library called “maven dependencies”. Eclipse WTP does not deploy out of the box this library. Inside the project configuration you will find a section called “j2ee module dependencies”. Just click the check box beside the “maven dependencies” library. Now all dependent libs are deployed as well. As controller act the CXFServlet and for spring need a listener to be defined both in the web.xml:

  cxf-sample
	
contextConfigLocation
WEB-INF/beans.xml
	


			org.springframework.web.context.ContextLoaderListener
		
	

	
		CXFServlet
		
			org.apache.cxf.transport.servlet.CXFServlet
		
		1
	

	
		CXFServlet
		/*
	

I use spring as main configuration tool. CXF depends on spring 2.0.8. The beans.xml imports the default cxf settings and defines the HelloWorld service:

The web service has a interface:

package demo.spring;

import javax.jws.WebService;

@WebService
public interface HelloWorld {
    String sayHi(String text);
}

and a implementation:

package demo.spring;

import javax.jws.WebService;

@WebService(endpointInterface = "demo.spring.HelloWorld")
public class HelloWorldImpl implements HelloWorld {

    public String sayHi(String text) {
        return "Hello " + text;
    }
}

If not set up a local server during creation of the project you need to go to the servers tab in eclipse. Define a new server with server type “Tomcat v6.0 Server”. If the adapter does not appear click on the link to “download additional server adapters”. Under “installed runtime” should be a tomcat 6 server. If not you have to add a new runtime. For tomcat 6 i recommend at least java 1.5 as jre. In the last step you can directly add the created project for cxf. Spring and CXF use commons logging for logging. So i provide in the classpath a simple log4j.xml to output everything interesting to std out:

Setup and implementation are now done. So i started the server inside eclipse. The console should contains lines from spring configuring cxf. To see a list of deployed web services just open a browser to http://localhost:8080/cxf-sample/services, where cxf-sample is the name of your eclipse project. You should see a list of links to the generated wsdl’s of the defined services. Copy the url to the HelloWorldImplPort in the clipboard. For testing i use the free tool soapui which will be started and installed by webstart. Choose under file the point “new wsdl project”. Give it a name and paste the url from the wsdl. Leave the tack for creating sample requests and choose ok. In the tree you see the project, the service, the operations and a request for each operation. Double Click on the only request for our service. Replace the ? with a value of your own inside the arg0 tag and hit the green run button:

   
   
      
         
         
         John Doe
      
   

You should see a response like that on right side of the request in a new window:

   
      
         Hello John Doe
