Hello,
i tried to create a pojo and load it to Guvnor which would call an EJB on
the same Jboss AS 7.1.
Below code works in another app without problem.
public class Calculation implements IFCalculation {
IFRemoteCalculation remoteCalculation;
public Calculation() {
final String jndiName =
"java:global/remoteejb/CalculationBean!com.gp.IFRemoteCalculation";
try {
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.as.naming.InitialContextFactory");
env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
Context ic = new InitialContext(env);
System.out.println("about to look up jndi name " + jndiName);
Object obj = ic.lookup(jndiName);
System.out.println("lookup returned " + obj);
remoteCalculation = (IFRemoteCalculation) obj;
} catch (NamingException e) {
System.out.println("Nem talatam meg a calculation beant! " + e);
}
}
public void add(String s, int faktor) {
remoteCalculation.add(s, faktor);
}
public String getItems() {
return remoteCalculation.getItems();
}
public void setItems() {
remoteCalculation.setItems();
}
}
When i load this as a POJO and try to use it in a Guvnor test scenario with
my rules i get following error:
12:47:17,673 ERROR [org.drools.guvnor.server.RepositoryAssetService]
(http--127.0.0.1-8080-5) Unable to run the scenario.: [Error: could not

It seems it is not possible to get InitialContext in a pojo uploaded to
Guvnor - or is there any way?
