Fast Infoset

[Joel Turkel <jo...@alumni.brown.edu>]

Hi,

Has anyone had any luck plugging in the java.net Fast Infoset reference implementation into CXF? I tried doing something like the following:

import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLOutputFactory;
import com.sun.xml.fastinfoset.stax.factory.StAXInputFactory;
import com.sun.xml.fastinfoset.stax.factory.StAXOutputFactory;

...

// Server setup
JaxWsServerFactoryBean serverFactory = new JaxWsServerFactoryBean();
serverFactory.setAddress("http://localhost:12345/MyService");
serverFactory.setServiceClass(MyService.class);
serverFactory.setServiceBean(new MyServiceImpl());       
Map<String,Object> properties = new HashMap<String,Object>();
properties.put(XMLInputFactory.class.getName(), new MyXmlInputFactory());
properties.put(XMLOutputFactory.class.getName(), new MyXmlOutputFactory());
serverFactory.setProperties(properties);       
serverFactory.create();

// Client setup
JaxWsProxyFactoryBean clientFactory = new JaxWsProxyFactoryBean();
clientFactory.setAddress("http://localhost:12345/MyService");
clientFactory.setServiceClass(MyService.class);
Map<String,Object> properties = new HashMap<String,Object>();
properties.put(XMLInputFactory.class.getName(), new StAXInputFactory());
properties.put(XMLOutputFactory.class.getName(), new StAXOutputFactory());
clientFactory.setProperties(properties);
MyService service = (MyService)clientFactory.create();

Unfortunately invoking any methods on client proxy results in the following exception because the Fast Infoset vocabulary has not been setup:

Setting up an empty vocabulary on the StAXDocumentSerializer seems to cause an infinite loop in org.apache.cxf.interceptor.WrappedOutInterceptor.handleMessage(). Anyone have any suggestions before I dig much deeper?

Thanks,
Joel
