WS with Camel CXF Jetty Guice - No Spring!
Hi,
I have an ESB based on Camel, Guice and Jetty. We're not doing any Spring at
the moment and would like to save that can of worms for another day.
But, Now I need to add an inbound CXF endpoint. All examples I can find is
with Spring. Could someone point me to a good example or write one up for
me?
This is basically what we're doing currently:
The very simple Route:
*******************************************************************************
package com....
import org.apache.camel.builder.RouteBuilder;
import javax.jws.WebService;
import java.util.Properties;
public class WSRouteBuilder extends RouteBuilder {
@Override
public void configure() throws Exception {
from("cxf:/eventListener?setDefaultBus=true&serviceClass=" +
Service.class.getName()).to("log:POST");
}
}
*******************************************************************************
The Servlet handle:
*******************************************************************************
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import java.util.Properties;
public class ApplicationServlet extends ApplicationBase implements
ServletContextListener {
...
@Override
public void contextInitialized(ServletContextEvent servletContextEvent)
{
try {
start();
servletContextEvent.getServletContext().setAttribute("injector",
injector);
} catch (Exception e) {
LOG.error(e.getMessage(), e);
throw new RuntimeException(e.getMessage(), e);
}
}
...
}
*******************************************************************************
As you see, I'm adding the guice injector to the servlet context. The guice
injector will provide the started CamelContext as a singleton. The
CamelContext contains the route. And then, the web.xml:
********************************************************************************
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<session-config>
<session-timeout>30</session-timeout>
</session-config>
<listener>
<listener-class>com....ApplicationServlet</listener-class>
</listener>
<servlet>
<servlet-name>MyCXFServlet</servlet-name>
<servlet-class>com....MyCXFServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>MyCXFServlet</servlet-name>
<url-pattern>/webservices/*</url-pattern>
</servlet-mapping>
</web-app>
**************************************************************************************
And finally extending the CXFNonSpringServlet as I could find in some
tutorials... But how do I create the bus and wire it properly???:
**************************************************************************************
package com...
import com.google.inject.Inject;
import com.google.inject.Injector;
import org.apache.camel.CamelContext;
import org.apache.camel.component.cxf.CxfEndpointUtils;
import org.apache.camel.component.cxf.transport.CamelTransportFactory;
import org.apache.cxf.Bus;
import org.apache.cxf.bus.CXFBusFactory;
import org.apache.cxf.bus.CXFBusImpl;
import org.apache.cxf.transport.servlet.CXFNonSpringServlet;
import javax.servlet.ServletConfig;
public class MyCXFServlet extends CXFNonSpringServlet {
@Inject
private CamelContext camelContext;
@Override
protected void loadBus(ServletConfig sc) {
super.loadBus(sc);
// Getting the injector from the context
Injector injector = (Injector)
sc.getServletContext().getAttribute("injector");
// Inject dependencies into this instance
injector.injectMembers(this);
????????????????????
??????setBus()???????
????????????????????
}
}
**************************************************************************************
Please help me with the setBus step!

Hi,
Thanks... It is as you say. It was me not getting the url right...
Had to do this though:
***************************************************************************
package com....;
import com.google.inject.Inject;
import com.google.inject.Injector;
import org.apache.camel.CamelContext;
import org.apache.cxf.BusFactory;
import org.apache.cxf.transport.servlet.CXFNonSpringServlet;
import javax.servlet.ServletConfig;
public class MyCXFServlet extends CXFNonSpringServlet {
@Override
protected void loadBus(ServletConfig sc) {
setBus(BusFactory.getDefaultBus());
}
}
*************************************************************************

Hi,
You don't need to addition work to setup the bus as CXF bus can live without Spring.
If you need to setup the bus, you may consider to call some CXF Java API to setup the features etc.
