No. Because Seam would have no metadata about that session bean. (Not in its classpath.) You can use standard EE injection (@EJB), however.

Hi Pete! Sure I can send! The only thing is that I can only post it tomorrow, code is at my job. I can even send a link for a sample project with code (war) and source, do you prefer? Tomorrow, 11 o clock Brazil time I'll send it. best regards, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4092375#4092375 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4092375 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Here goes a sample:
for foobean.jar
foo.bar.server.ejb.IFoo
| package foo.bar.server.ejb;
|
| public interface IFoo {
| public void bar();
| }
|
foo.bar.server.ejb.IFooRemote
| package foo.bar.server.ejb;
|
| import javax.ejb.Remote;
|
| @Remote
| public interface IFooRemote extends IFoo {
| }
|
foo.bar.server.ejb.impl.FooBean
| package foo.bar.server.ejb.impl;
|
| import javax.ejb.Stateless;
| import foo.bar.server.ejb.IFooRemote;
|
| @Stateless
| public class FooBean implements IFooRemote {
| public void bar() {
| System.out.println("FOOBAR");
| }
| }
|
and I have an ant target that packs up the contents of the foo.bar.server.ejb
package as a jar to be added on WEB-INF/lib folder of the foo.war.

I am not deploying as an EAR since the project is still under development, so I
have an ant target that recreates the war and calls the JBoss JMX Bean for
deploying the WAR/JAR in my workspace. Anyways, when I deploy it as an EAR I'll
setup links for the SessionBeans using jboss.xml file in order to make them
have the same JNDI name.
If you prefer that I upload to somewhere the Eclipse projects just post a
message and I can upload them (with build scripts and etc).
best regards,

[jboss-user] [JBoss Seam] - Re: Seam EJB Injection Classloading issue
I thought it was clear enough on the post below and that was the reason I suggested uploading somewhere the project... I am not deploying EJBs inside an WAR. I am packaging the interfaces for the classes (aka EJB-client package) so I can refer to the SessionBeans inside my Web Application. I am packaging only the interfaces not the implementation classes. Lets try to be very straightforward... Is Seam supposed to be able to inject a reference for a SessionBean deployed anywhere in a JNDI compliant Server using @In annotation? Cause if so either I am doing something wrong or there seems to be something not working as expected. I am already using an workaround to avoid this... plain simple ServiceLocator pattern...

[jboss-user] [JBoss Seam] - Re: Seam EJB Injection Classloading issue
No, but Seam needs the class to be available to its classloader. I think I got confused and thought this should work - but it only works for local ejbs not remote (where Seam can get at the actual implementation class). So I suggest you use the @Unwrap/manager pattern to make your remote ejbs into Seam components (you could easily make a generic component and instantiate lots through components.xml).

[jboss-user] [JBoss Seam] - Re: Seam EJB Injection Classloading issue
Hmm... ok... now we have two confused :D I am ok about Seam not supporting remote EJBs but still I feel confused about it supporting local since theoretically the both should have a common behavior in relation to the client. Errr... Let me try to be clearer... I dont follow how Seam accesses the EJB "directly" when it is a local ejb since in theory all EJB access is meant to be done through the Proxy class that is created by the container. Or am I wrong? Anyway, tks a lot Pete! I'll try the manager tip!

[jboss-user] [JBoss Seam] - Re: Seam EJB Injection Classloading issue
The problem isn't accessing the EJB instance (which Seam accesses it through JNDI), but rather the implementing class (which I'm infering isn't on your war's classpath, but on the classpath of the ear which contains it - whats on your wars classpath is the remote interface). I think this is a limitation of the way the component model is implemented that just was never removed (as opposed to a real restriction of the design of Seam's component model). Feel free to file a feature request for this - I want to see what Gavin says.
