[EJB 3.0] - Re: ant failed.
by samwan809
Hi, I finally got that working.
Now the problem is with my Client.java code.
Here is the errors I am getting:
| ...
| Test:
| [junit] Testsuite: com.ip6networks.calling_card_registration.test.Client
| [junit] Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 1.497 sec
| [junit]
| [junit] ------------- Standard Error -----------------
| [junit] javax.naming.NamingException: Could not dereference object [Root exception is java.lang.reflect.UndeclaredThrowableException]
| [junit] at org.jnp.interfaces.NamingContext.getObjectInstanceWrapFailure(NamingContext.java:1463)
| [junit] at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:809)
|
|
Here is the Client.java source code:
| package com.ip6networks.calling_card_registration.test;
|
| import junit.framework.*;
| import com.ip6networks.calling_card_registration.test.Calculator;
| import com.ip6networks.calling_card_registration.test.CalculatorRemote;
| import com.ip6networks.calling_card_registration.test.ServiceLocator;
|
| public class Client extends TestCase
| {
|
| public void testCalculator() throws Exception
| {
| Calculator calculator = getSession();
| System.out.println("in Client class");
| System.out.println("1 + 1 = " + calculator.add(1, 1));
| System.out.println("1 - 1 = " + calculator.subtract(1, 1));
|
| }
|
| private static Calculator getSession() throws Exception {
| Calculator mgr = null;
| mgr = (Calculator) ServiceLocator.getInstance().getService("Calculator");
| if (mgr == null) {
| //throw new SystemErrorException("Unable to connect to service");
| throw new Exception("Unable to connect to service");
| } else {
| return mgr;
| }
| }
| }
|
|
Source code for ServiceLocator.java:
| package com.ip6networks.calling_card_registration.test;
|
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import java.util.*;
| import org.apache.commons.logging.LogFactory;
| import org.apache.commons.logging.Log;
|
| public class ServiceLocator {
| private Map<String, java.lang.Object> cache;
| private static ServiceLocator ourInstance = new ServiceLocator();
| private static final Log logger = LogFactory
| .getLog(ServiceLocator.class);
|
| public static ServiceLocator getInstance() {
| return ourInstance;
| }
|
| private ServiceLocator() {
| this.cache = Collections.synchronizedMap(
| new HashMap<String, java.lang.Object>());
| }
|
| public java.lang.Object getService(String serviceName) {
| String serviceHost = "192.168.1.242";
| if (this.cache.containsKey(serviceName)) {
| return this.cache.get(serviceName);
| }
|
| try {
| java.lang.Object service = this.getContext(
| serviceHost).lookup(
| serviceName + "Bean/remote");
| cache.put(serviceName, service);
| return service;
| } catch (Exception e) {
| e.printStackTrace();
| logger.error("Unable to bind to service "
| + serviceName + ". Hostname: " + serviceHost, e);
| return null;
| } catch (Throwable e) {
| e.printStackTrace();
| logger.error("Unable to bind to service "
| + serviceName + ". Hostname: " + serviceHost, e);
| return null;
| }
|
| }
|
| public java.lang.Object getService(String serviceName, String serviceHost) {
| String key = serviceHost + "." + serviceName;
| if (this.cache.containsKey(key)) {
| return this.cache.get(key);
| } else {
| try {
| java.lang.Object service = this.getContext(
| serviceHost).lookup(
| serviceName + "Bean/remote");
| cache.put(key, service);
| return service;
| } catch (Exception e) {
| logger.error("Unable to bind to service "
| + serviceName + ". Hostname: " + serviceHost);
| return null;
| }
| }
| }
|
| private Context getContext(String serviceHost) throws javax.naming.NamingException
| {
| Properties properties = new Properties();
| properties.put(Context.INITIAL_CONTEXT_FACTORY,
| "org.jnp.interfaces.NamingContextFactory");
| properties.put(Context.URL_PKG_PREFIXES,
| "org.jboss.naming:org.jnp.interfaces");
| properties.put(Context.PROVIDER_URL, serviceHost + ":1099");
| return new InitialContext(properties);
| }
| }
|

If I run this code in the jboss environment (that is /usr/java-source/ejb3-tutorial/source/stateless), it runs well.
Thanks
Sam
