[openjms-developer] Failed to create session: java.security.AccessControlException

[a***@neoxia.com]

Hi,

I have developped a small applet which subscribes to a topic. My openjms server
is properly running because I am able via a standard java application to
publish/subscribe to "topic1", receive message using the http configuration
file...

However from my applet it raises an AccessControlException. Does someone have
any idea ?

applet source code :
import java.applet.Applet;
import javax.jms.*;
import javax.naming.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;

public class TestJmsApplet extends Applet {
private TextField subject;
private TextField data;
private FlowLayout layout;
private Button button;
private InitialContext context;
private TopicConnectionFactory factory;
private TopicConnection connection;
private TopicSession session;
private Topic topic;
private TopicSubscriber subscriber;
private TextMessage message;

/**

public void init() {

Hashtable properties = new Hashtable();

try {
super.init();

properties.put(Context.PROVIDER_URL,"http://127.0.0.1:
8080/openjms/OpenJMSJndi");
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.exolab.jms.jndi.http.
HttpJndiInitialContextFactory");
properties.put(Context.PROVIDER_URL, "http://127.0.0.1:
8080/openjms/OpenJMSJndi");
context = new InitialContext(properties);
}
catch (Exception e) {
e.printStackTrace();
}

this.setLayout(new FlowLayout());

subject = new TextField("Enter your subject", 19);
subject.setVisible(true);
this.add(subject);

data = new TextField("Data received", 19);
data.setVisible(true);
this.add(data);

button = new Button("Subscribe");
button.setVisible(true);
button.addMouseListener(new MouseListener() {
public void mousePressed(MouseEvent e) {
subscribe();
start();
return;
}

public void mouseClicked(MouseEvent e) {

return;
}

public void mouseEntered(MouseEvent e) {
return;
}

public void mouseExited(MouseEvent e) {
return;
}

public void mouseReleased(MouseEvent e) {
return;
}
});

this.add(button);

this.setVisible(true);
this.validate();
}

/**

public void start() {
return;
}

/**

public void paint(Graphics g) {
return;
}

/**

public void subscribe() {
Thread thread;
String sub = subject.getText();
subject.setText("Subscribe to " + sub);

try {
factory = (TopicConnectionFactory)context.
lookup("HTTPTopicConnectionFactory");
connection = factory.createTopicConnection();
connection.start();
session = connection.createTopicSession(false, Session.
AUTO_ACKNOWLEDGE);
topic = (Topic)context.lookup(sub);
subscriber = session.createSubscriber(topic);
thread = new Thread() {
public void run() {
try {
while (true) {
message = (TextMessage)subscriber.receive();
data.setText(message.getText());
}
}
catch (Exception e) {
e.printStackTrace();
}
}
};
thread.start();
}
catch (Exception e) {
e.printStackTrace();
}


return;
}
}
