Dear experts,

I'm trying to implement Apache CXF in CQ. I've generated proxy classes from WSDL using cxf-codegen-plugin. Now my CxfServiceImpl.java looks like below -

import net.webservicex.ConvertTemperatureSoap;
import net.webservicex.TemperatureUnit;

import org.apache.felix.scr.annotations.Activate;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Service;
import org.osgi.framework.BundleContext;
import org.osgi.service.component.ComponentContext;

@Component(label = "CXF Service", immediate = true, metatype = true)
@Service(CxfService.class)
public class CxfServiceImpl implements CxfService {
private ConvertTemperatureSoap convertTemperatureSoap;

@Override
public double convertCelsiusToFahrenheit(double valueToConvert) {
   return convertTemperatureSoap.convertTemp(
   valueToConvert,
   TemperatureUnit.DEGREE_CELSIUS,
   TemperatureUnit.DEGREE_FAHRENHEIT);
}

@Activate
protected final void activate(final ComponentContext context) {
convertTemperatureSoap =
JaxWsClientFactory.create(
ConvertTemperatureSoap.class,
"http://www.w3schools.com/webservices/tempconvert.asmx"); }
}

JaxWsClientFactory.java looks like -

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.BusFactory;
public class JaxWsClientFactory {
   public static <T> T create(Class<T> clazz, String portUrl) {
   ClassLoader oldClassLoader = Thread.currentThread().getContextClassLoader();
   try {
      Thread.currentThread().setContextClassLoader(BusFactory.class.getClassLoader());
       JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
       factory.setServiceClass(clazz);
   factory.setAddress(portUrl);
   return (T) factory.create();
   }
   finally {
   Thread.currentThread().setContextClassLoader(oldClassLoader);
   }
   }
}

I am able to create OSGI bundle and uploaded in Felix console. But when I try to activate bundle then I get error as below and bundle status is showing as Active. Attached is the pom.xml. Sincerely thanks for your help!

I have successfully built Java proxy classes using CFX WSDL to Java and have successfully created an OSGi bundle that works within AEM:

[img]CFXWS.png[/img]

I will write this up as a community article and post the URL from this thread.

Basic steps:

1 - download CXF and create the Java proxy classes:

C:\ApacheCXF\apache-cxf-2.6.0\bin>wsdl2java -p com.aem.ws -d c:\proxyfiles
http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

2 - bundle the files (located in c:\proxyfiles -- see -d in previous command) into a JAR (all proxy classes are in a Java package named com.aem.ws -- see -p in the CXF command).

3 - Use Eclipse to build an OSGi bundle via the plug-in project. Import the JAR that contains the Java web service proxy files.

4 - Deploy the OSGi to AEM. Place into an Active State.

5- Consume the OSGi from a JSP:

<%@include file="/libs/foundation/global.jsp"%>
<h1><%= properties.get("title", currentPage.getTitle()) %></h1>

<h2>Here is an AEM service created from Apache CXF Java proxy classes:</h2>
<%

com.aem.ws.Weather weather = new com.aem.ws.Weather();

com.aem.ws.WeatherSoap wsaop = weather.getWeatherSoap();

com.aem.ws.WeatherReturn wr = wsaop.getCityWeatherByZIP("95101");

%>

<h2>The following describes the weather for 95101 ZIP Code</h2>
<h3><%= "The city is " +wr.getCity()%></h3>
<h3><%= "The state is " +wr.getState()%></h3>
<h3><%= "The description is " +wr.getDescription()%></h3>
<h3><%= "The wind is " +wr.getWind()%></h3>
<h3><%= "The current temp is " +wr.getTemperature()%></h3>
<h3><%= "The current Humidity is " +wr.getRelativeHumidity()%></h3>

Also - modify the sling.properties to use web services as discussed in the web service article. See http://helpx.adobe.com/experience-manager/using/creating-cxf-bundles-consume-web.html.

Can you try using JAX-WS and follow this web service article. This has been tested numerous times and successfully consumes a 3rd party web service:

Thanks Scott for your help as always!

I've already gone through this link but this link does not talk about CXF. I'm looking for CXF implementation.

Yes - the current way that we have documented CQ and web services is using JAX-WS to generate the Java proxy classes. We successfully got it talking to a 3rd party WSDL:

[img]WSClient.png[/img]

However, what we will do is take this use case, and add it to the community article list. Then we will work through it, and develop a community article with working code.

In the mean-time - if any other community member has worked with CXF - please let us know what happened.

The example web service uses USA zip codes.
