Annotations working in Tomcat
I got annotations mostly working in Tomcat. To try this out, install
OpenEJB into Tomcat as noted before and simply add @EJB and @Resource
annotations to your servlet fields. I added an very simply servlet-
samples application which can be checked out with:
svn co http://svn.apache.org/repos/asf/openejb/trunk/openejb3/
examples/servlet-samples
This is a completely standalone sample and should be an easy starting
point. One critical thing to note about the example is the use of
<scope>provided</scope> in the maven pom.xml file to stop maven from
including duplicate copies of the annotation classes into the web
application.
For those that don't want to download the code, here is it:
public class AnnotatedServlet extends HttpServlet {
@EJB private AnnotatedEJBLocal ejb;
@Resource private DataSource ds;
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/plain");
ServletOutputStream out = response.getOutputStream();
out.println("@EJB=" + ejb);
if (ejb != null) {
out.println("@EJB.getName()=" + ejb.getName());
out.println("@EJB.getDs()=" + ejb.getDs());
}
out.println("@Resource=" + ds);
}
}
@Stateless
public class AnnotatedEJB implements AnnotatedEJBLocal {
@Resource private DataSource ds;
private String name = "foo";
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public DataSource getDs() {
return ds;
}
public void setDs(DataSource ds) {
this.ds = ds;
}
public String toString() {
return "AnnotatedEJB[name=" + name + "]";
}
}
public interface AnnotatedEJBLocal {
String getName();
void setName(String name);
DataSource getDs();
void setDs(DataSource ds);
}

I'm going to be tuning the code over the next couple of days, but it
generally works now. Let me know if you find any bugs, or most
importantly if it doesn't work as you would expect Tomcat to work.
One of my goals is to not violate any expectations of Tomcat users,
so if something stops working like is used to do, let me know ASAP.
The integration should feel like the Tomcat team wrote it themselves.

Thats my bad. I should've updated the example. The default JNDI name
strategy has changed. Now the default JNDI name of the bean is going
to be "GreetingBeanRemote".

I implemented redeploy in trunk and 3.0-beta-1. I also refreshed all

That could be. "Unknown reason" is really "hasn't been
investigated". Might be our test suite isn't cleaning up properly?

Thanks again, I got it working now from svn (still need to update the openejb-tmp
downloads).
One more thing, the 21 errors that occur from running the tests twice, is it really
a "unknown reason"? Seems like a hsqldb driver message due to still having some
lock on previously closed sessions.

If you check the servlet-samples, you will see I added an annotated
remote interface to the code.

Based on the stacktrace it appears that your remote interface
includes the "DataSource getDs();" method. When you call this
method, you get a NotSerializableException because a DataSource
object is not serializable. The EJB specification restricts remote
interface to only use serializable data types.
If you remove this method, I bet your code will work.

You don't have the remote interface in your examples, but adding one still gives me
the following when getting the datasource:

It's fixed in your war file but still broken in the current snapshot.
I also noticed that I can't "undeploy" the beans by reloading the web application
(or both the web app and openejb for that matter). Is it possible to avoid
restarting Tomcat every time one just wants to reload the web app?
This is what I get when I try to reload (from Tomcat manager):

I added the @Local annotation to the AnnotatedEJBLocal interface and
added a @Remote AnnotatedEJBRemote interface to the example; both
work fine for me.
Can you try the servlet-examples war?
As for the test client jar, I rewrote the packing configuration for
it the other day, and tested it on linux and windows. So, if it was
broken before, I'm confident it is fixed now :)

Dain,
Correct, I can't get remote interfaces working (you left out the @Local annotation
in your example). I also noticed that the optional tests client jar is packaged
incorrectly (had to unpack it to be able to find and run the Main class).

Can you try my example directly? There may be something wrong with
Karan's example or maybe remote business interfaces are broken.

Re: Annotations working in Tomcat

Dain,
Thanks for the work! I've updated the "New Instructions" adding the manual steps for
Windows users, you can try including this in your installer. Just a minor comment, I
also copied the agent jar in addition to the loader jar into Tomcat's lib folder
because hardcoding to webapps/openejb/lib may be a problem should webapps be changed
or openejb be deployed w/o unpacking the war/zip.
Now for the example, I'm getting the following error:
javax.naming.NameNotFoundException: Name "org.acme.TestServlet/ejb" not found.
I tried out your example by adding it to the previous example Karan posted but even
that one no longer works for me:
javax.naming.NameNotFoundException: Name "GreetingBeanBusinessRemote" not found.
Maybe I'm still missing something?
