Subject Re: TransactionManager resource - no provider error
Date Tue, 10 Nov 2009 22:19:57 GMT
Actually this is one of those things that a bean is not supposed to be  
able to do and is the purpose of the UserTransaction object.  If you  
can use that instead I definitely would as it will be portable to all  
impls that pass the Java EE TCK.

That said, you could add support for injection of that type via a  
PropertiesEditor like this one:

   import javax.naming.InitialContext;
   import javax.naming.NamingException;
   import javax.transaction.TransactionManager;
   import java.beans.PropertyEditorManager;

   public class TransactionManagerEditor extends  
java.beans.PropertyEditorSupport {

       static {
            
PropertyEditorManager.registerEditor(TransactionManager.class,  
TransactionManagerEditor.class);
       }

       public void setAsText(String text) throws  
IllegalArgumentException {
           try {
               InitialContext context = new InitialContext();
               Object o = context.lookup("openejb:TransactionManager");
               setValue(TransactionManager.class.cast(o));
           } catch (NamingException e) {
               throw new IllegalStateException(e);
           }
       }
   }

   (or here: http://gist.github.com/231273 )

You just need to make sure the TransactionManagerEditor loads fairly  
early or move the register code close to the class where the  
TransactionManager is needed.

This *should* do the trick.  You might need to add a corresponding  
<env-entry>, not sure if we require that.  If we do you can use the  
env-entries.properties file which will not conflict with JBoss at  
all.  (see http://openejb.apache.org/3.0/custom-injection.html)

We could probably add built in support for this, but for now the above  
should work.

I've added a jira for "extended" types usable with @Resource (i.e. non- 
standard), just to make sure we don't loose the feedback:

   https://issues.apache.org/jira/browse/OPENEJB-1104

Feel free to add some more if you have any you need.  Here's the  
standard list:

   https://issues.apache.org/jira/browse/OPENEJB-370

Not sure if that is comprehensive, but seems to be just missing  
UserTransaction.
