Why I get this error in CXF_问答_开发者_运维开发者技术经验分享

I want to make dynamic web service invoker in JSF with CXF. But when I load this simple code I get error. The code:

JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl");

The error:

No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configu开发者_运维知识库ration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions! If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml. A typical config looks like this; org.apache.myfaces.webapp.StartupServletContextListener

Caused by: java.lang.IllegalStateException - No Factories configured for this Application.

Any Idea how to solve the problem?

    This parameter tells MyFaces if javascript code should be allowed in
    the rendered HTML output.
    If javascript is allowed, command_link anchors will have javascript code
    that submits the corresponding form.
    If javascript is not allowed, the state saving info and nested parameters
    will be added as url parameters.

    If true, rendered HTML code will be formatted, so that it is 'human-readable'

    If true, a javascript function will be rendered that is able to restore the

In order to avoid some error like "No Factories configured for this Application" using a CXF Dynamic Client and JSF, you must to do something like this:

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://ws.strikeiron.com/IPLookup2?wsdl");
Thread.currentThread().setContextClassLoader(classLoader);

The errors you quote have nothing to do with CXF, but rather with org.apache.myfaces.

If all that came back from the server, then you have the wrong URL for the ?wsdl. Does browsing that URL produce the WSDL file in an ordinary browser?

You can probably get better debugging assistance on this at the CXF user mailing list. This isn't so much a question as a diagnostic issue that will take a lot of back and forth.
