Hi,

I'm trying to set up the "File System Adapter" like shown here  http://docs.jboss.org/jbossas/jboss4guide/r4/html/ch7.chapt.html http://docs.jboss.org/jbossas/jboss4guide/r4/html/ch7.chapt.html
First I build the rar-archive and moved it to the deploy-folder together with the MBean descriptor (notxfs-ds.xml). So far so good. The admin console and the jmx-console showed me that the AS now knows an the connection-factoty

JMX (jboss.jca)

Now I'd like to use it in my beans to use file access without using java.io.* so I used the following code:


import javax.annotation.Resource;
import javax.resource.cci.ConnectionFactory;
 
...
 
    @Resource(name="NoTransFS")
    private DirContextFactory dcf;
 
    public String action() {
        try {
            DirContext dc = dcf.getConnection();
            NamingEnumeration<SearchResult> res = dc.search("myFile", null);
            while (res.hasMore()) {
                System.out.println(res.next().toString());
            }
        } catch (NamingException e) {
            e.printStackTrace();
        }
        return null;
    }
 
...   


Unfortunately I can't look up the ConnectionFactory so I'll always receive a NullPointerException.I tried several kinds of the @Resource annotation but nothing works out. Maybe the JNDIView helps somebody to give me some hints:

May anybody help me with this problem?`Thanks a lot
