问题
I have written a simple Ejb program, by looking from
http://mrbool.com/how-to-use-enterprise-java-beans-3-x-based-application-with-websphere-8-5-application-server/28063
The files are
package ejb3.test;
import javax.ejb.Remote;
/**
* TODO: Document me!
*
* @author aprashanth
*
*/
@Remote
public interface ITestEJBRemoteInterface {
public boolean checkNames(String fsName);
}
Implementation Class:
package ejb3.test;
/**
* TODO: Document me!
*
* @author aprashanth
*
*/
import java.util.Arrays;
import java.util.List;
import javax.ejb.Stateless;
/** * Session Bean implementation class TestEJB */
@Stateless
public class TestEJB implements ITestEJBRemoteInterface {
List<String> moListOfNames = Arrays.asList("Kevin","Jiten","Martina","Brian");
/** * Default constructor. */
public TestEJB() { }
/** * Find if the passed name is present in the default list of names * *
*
* @return */
public boolean checkNames(String fsName) {
boolean lboolNamePresent = false;
if(fsName != null)
{
lboolNamePresent = moListOfNames.contains(fsName);
}
return lboolNamePresent;
}
}
Ejb-jar.xml:
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd" version="3.1">
<display-name>TestEJB3 </display-name>
<ejb-client-jar>TestEJB3Client.jar</ejb-client-jar>
</ejb-jar>
At the client side:
I have created the stub using createStub.bat of IBM.and that jar is imported at the client side.
package ejb31.test;
/**
* TODO: Document me!
*
* @author aprashanth
*
*/
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import ejb3.test.ITestEJBRemoteInterface;
public class TestEJBClient {
/** * @param args */
public static void main(String[] args) {
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
props.put(javax.naming.Context.PROVIDER_URL, "iiop://localhost:2809");
ITestEJBRemoteInterface loEJB =null;
Object lobj; try { InitialContext ctx = new InitialContext(props);
lobj = ctx.lookup("checkName");
if (lobj instanceof ITestEJBRemoteInterface) {
loEJB = (ITestEJBRemoteInterface) lobj;
}
String lsName = "Imran";
System.out.println("Is "+ lsName + " present in the list:: "+loEJB.checkNames(lsName));
System.out.println("EJB run successful");
} catch (NamingException e) {
e.printStackTrace();
}
}
}
My project structure and the imported libraries as in the below figure:
At the WAS side, setup steps are as below: Port
Installation Steps
Lastly JndI Configuration.
When I run the client code, I get the following error.
JSAS1480I: Security is not enabled because the ConfigURL property file is not set.

回答1:
Hmm, you have to look better on your screenshot, as it is clearly visible that Enable Administrative Security is CHECKED.
So you either have to disable SSL in the RMI/IIOP inbound transport configuration, or properly configure your client to use SSL.
Something like this:
<java_install_root>/bin/java
-classpath com.ibm.ws.ejb.thinclient_8.5.0.jar:<list_of_your_application_jars_and_classes>
-Djava.naming.provider.url=iiop://<your_application_server_machine_name>
-Dcom.ibm.SSL.ConfigURL=file:///home/user1/ssl.client.props
-Dcom.ibm.CORBA.ConfigURL=file:///home/user1/sas.client.props
<fully_qualified_class_name_to_run>
For details check the following page - Running the IBM Thin Client for Enterprise JavaBeans (EJB)
UPDATE
Now you have issue in the code. You have to use PortableRemoteObject.narrow for unmanaged clients.
Instead of:
Object lobj; try { InitialContext ctx = new InitialContext(props);
lobj = ctx.lookup("checkName");
if (lobj instanceof ITestEJBRemoteInterface) { // <##### this is the problem
loEJB = (ITestEJBRemoteInterface) lobj;
}
use:
lobj = initCtx.lookup(ejbJNDIName);
loEJB = (ITestEJBRemoteInterface) javax.rmi.PortableRemoteObject.narrow(lobj , ITestEJBRemoteInterface.class);
