Our current application has a requirement to route all remote EJB calls used for batch jobs through an MDB to facilitate retries. As a result, I need to invoke the remote EJB through reflection.
When looking up the remote EJB3 interface, the returned value from the ctx.lookup(envProperties) call is actually a proxy object and not the real one which is expected. Thus, when looking up the method using clazz.getMethod(..) throws a NoSuchMethodException.
Below is my code.
The Remote Interface:
package my.interface.package;
import java.io.Serializable;
import java.util.Date;
import java.util.List;
public interface MyServiceBeanRemoteInterface extends Serializable {
public List<Long> callBatchJob(Date batchDate, long batchId, boolean flag);
}
Lookup code:
final Properties env = new Properties();
env.put("java.naming.factory.url.pkgs","org.jboss.ejb.client.naming");
env.put("remote.connections","default");
env.put("endpoint.name","client-endpoint");
env.put("remote.connection.default.host","localhost");
env.put("remote.connection.default.port","4447");
env.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED","false");
env.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS","false");
env.put("remote.connection.default.username","testuser");
env.put("remote.connection.default.password","testpassword");
Context ctx = new InitialContext(env);
Object lookup = ctx.lookup( "ejb:myapp/business/MyServiceBean!my.interface.package.MyServiceBeanRemoteInterface");
Class<? extends Object> clazz = lookup.getClass();
/* Fails at below line */
Method method = clazz.getMethod("callBatchJob", Date.class, Long.class, Boolean.class);
Object returnValue = method.invoke(lookup, new Date(), Long.valueOf(6), true);
How do I work around this? The implementation class can vary.
