Pessoal,

Estou começando a brincar com EJB 2.1 usando o Apache Geronimo 1.1 no Eclipse.
Um dos exemplos que eu fiz (Exam Study Kit - Manning) usa um stateless Session Bean que ta dando pau na hora do lookup
Eu to usando OpenEJB. Abaixo o código do client e tb o ejb-jar.xml alem da exception..

Se alguem puder me ajudar, acho que tem algo errado no .xml

#FortuneClient.java ##

public static void main(String[] args) {
    try {
	Properties props = System.getProperties();
	props.put(Context.INITIAL_CONTEXT_FACTORY,
	"org.openejb.client.RemoteInitialContextFactory");
	props.put(Context.PROVIDER_URL, "localhost:4201");
	props.put(Context.SECURITY_PRINCIPAL, "system");
	props.put(Context.SECURITY_CREDENTIALS, "manager");
			
	Context ictx = new InitialContext(props);
	Object objref =
		ictx.lookup("java:comp/env/ejb/FortuneSelector");
	FortuneHome home =
		(FortuneHome)PortableRemoteObject.narrow(objref,
			FortuneHome.class);
	Fortune fortuner = home.create();
	System.out.println(fortuner.getNextFortune());
	System.exit(0);
    } catch (Exception ex) {
	System.err.println("Caught an exception!");
	ex.printStackTrace();
    }
}

## ejb-jar.xml ##

&lt;display-name&gt;FortuneBean&lt;/display-name&gt;
	&lt;enterprise-beans&gt;
		&lt;session&gt;
			&lt;display-name&gt;FortuneBean&lt;/display-name&gt;
			&lt;ejb-name&gt;FortuneCookieBean&lt;/ejb-name&gt;
			&lt;home&gt;FortuneHome&lt;/home&gt;
			&lt;remote&gt;Fortune&lt;/remote&gt;
			&lt;ejb-class&gt;FortuneBean&lt;/ejb-class&gt;
			&lt;session-type&gt;Stateless&lt;/session-type&gt;
			&lt;transaction-type&gt;Bean&lt;/transaction-type&gt;
			&lt;ejb-ref&gt;
				&lt;ejb-ref-name&gt;ejb/FortuneSelector&lt;/ejb-ref-name&gt;
				&lt;ejb-ref-type&gt;Session&lt;/ejb-ref-type&gt;
				&lt;home&gt;FortuneHome&lt;/home&gt;
				&lt;remote&gt;Fortune&lt;/remote&gt;
				&lt;ejb-link&gt;FortuneCookieBean&lt;/ejb-link&gt;
			&lt;/ejb-ref&gt;
			&lt;security-identity&gt;
				&lt;description&gt;&lt;/description&gt;
				&lt;use-caller-identity&gt;&lt;/use-caller-identity&gt;
			&lt;/security-identity&gt;			
		&lt;/session&gt;
	&lt;/enterprise-beans&gt;

mais uma coisa, a exception que o Geronimo dá é a seguinte:

09:54:18,328 ERROR [JndiRequestHandler] JNDI request error java.lang.IllegalArgumentException: uri path must be in the form [groupId]/[artifactId]/[version]/[type] : /java:comp/env/ejb/FortuneSelector

Obrigado

troque a linha

Object objref =

ictx.lookup(“java:comp/env/ejb/FortuneSelector”);

por

Object objref =

ictx.lookup(“FortuneSelector”);

Desculpe,

troque então o

Object objref = ictx.lookup(“java:comp/env/ejb/FortuneSelector”);

por

Object objref = ictx.lookup(“FortuneCookieBean”);

Cara funcionou, só que eu tive que baixar um jar e colocar no classpath:

que eu encontrei aqui:

Valeu…
