Hello guys i've got a problem in sending an Object to sever by remote (EJB3)
technology framework
take look at my code
in server side
| @Remote
| public interface TestRemote {
| public void sendObject(Object obj);
| }
|
| @Stateless
| public class TestBean implements TestRemote {
| public void sendObject(Object obj) {
| System.out.println("Object is Coming");
| }
| }
in client side (swing)
| public class H implements Serializable {
| private static final long serialVersionUID = 1L;
| private int id;
|
| public void setId(int id) {
| this.id = id;
| }
|
| public int getId() {
| return id;
| }
| }
|
| public class RunMe {
| public RunMe() {
| try {
| Properties prop = new Properties();
|
|
prop.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
|
prop.setProperty("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
|
prop.setProperty("java.naming.provider.url","localhost:1099");
|
| Context ctx = new InitialContext(prop);
| System.out.println("Step 1");
|
| ClassLoader cl =
Thread.currentThread().getContextClassLoader();
| Class k = cl.loadClass("client.H");
|
| H h = (H) k.newInstance();
| h.setId(44);
|
|
| System.out.println("Step 2");
| //Thread.currentThread().getContextClassLoader().
| RunMeRemote r = (RunMeRemote)
| ctx.lookup("RunMe/remote");
| r.setObject(h);
|
| } catch (Exception e) {
| System.out.println(e);
| }
| }
| public static void main(String[] st) {
| new RunMe();
| }
| }
|
when I run this program i encountered to this exception
Step 1
Step 2
log4j:WARN No appenders could be found for logger
(org.jboss.security.SecurityAssociation).
log4j:WARN Please initialize the log4j system properly.
java.lang.RuntimeException: java.lang.ClassNotFoundException: No ClassLoaders
found for: client.H (no security manager: RMI class loader disabled)
when i add this code
| public class Client {
|
|
|
| @SuppressWarnings("unchecked")
| public Client() {
| try {
| Properties prop = new Properties();
|
|
prop.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
|
prop.setProperty("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
|
prop.setProperty("java.naming.provider.url","localhost:1099");
|
| Context ctx = new InitialContext(prop);
| if (System.getSecurityManager() == null) {
| System.setSecurityManager(new
RMISecurityManager());
| }
| System.out.println("Step 1");
|
| ClassLoader cl =
Thread.currentThread().getContextClassLoader();
| Class k = cl.loadClass("client.H");
|
| H h = (H) k.newInstance();
| h.setId(44);
|
|
| System.out.println("Step 2");
| //Thread.currentThread().getContextClassLoader().
| RunMeRemote r = (RunMeRemote)
ctx.lookup("RunMe/remote");
| r.setObject(h);
|
| } catch (Exception e) {
| System.out.println(e);
| }
|
| }
|
| public static void main(String[] s) {
|
| new Client();
| }
|
| }
|
another exception is appeared
Step 1
Step 2
log4j:WARN No appenders could be found for logger
(org.jnp.interfaces.NamingContext).
log4j:WARN Please initialize the log4j system properly.
javax.naming.CommunicationException: Could not obtain connection to any of
these urls: localhost:1099 and discovery failed with error:
java.security.AccessControlException: access denied (java.net.SocketPermission
230.0.0.4 connect,accept,resolve) [Root exception is
javax.naming.CommunicationException: Failed to connect to server localhost:1099
[Root exception is java.security.AccessControlException: access denied
(java.net.SocketPermission 127.0.0.1:1099 connect,resolve)]]
Mention. when i want to send a String or int or any prmetive java Object my
program works good and send the date for sever
but when i want to send an object (Entity Object) the exception is appeared.
tell what should i do to send an Object to sever by remote (EJB3) Technology?
thanks so much
