Summary: Cannot get EJB Home interface from Remote interface
Initial Comment:
One cannot get an EJB home interface from a remote
interface (using getEJBHome()) when the JNDI connection
properties are not set in the System property space.
The following code fragment illustrates the problem:
==============================
Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
// host must be remote, not local
props.setProperty(Context.PROVIDER_URL,"remotehost:1099");
props.setProperty(Context.URL_PKG_PREFIXES,"org.jboss.naming");
InitialContext ctx = new InitialContext(props);
FooHome foohome = (FooHome)ctx.lookup("ejb/foohome");
Foo foo = foo.findByPrimaryKey(id);
EJBHome home = foo.getEJBHome();
==============================
The last line will fail with a
java.lang.reflect.UndeclaredThrowableException caused
by a java.net.SocketTimeoutException.
I have traced the problem to
org.jboss.proxy.ejb.GenericEJBInterceptor.getEJBHome(Invocation).
which has the line
InitialContext iniCtx = new InitialContext();
and therein lies the problem. This assumes that the
JNDI connection properties have been set in the System
property space which is not the case in the above example.
The remote interface must have explicit access to the
JNDI properties used to retrieve it in the first place.
It cannot assume that these properties have been set
in the System property space.
Note that this problem also exists in v3.2. It does
not exist in 2.4.x.
