Hello,


Could somebody explain what to do if you want to enable dynamic class loading for J2EE application clients (Swing client to be more precisely).

According to the documentation, the WebService, listening at http://[host_name]:8083 provides the dynamic class loading service.

I also found that you need to set some system properties at client application level to find the class providing service.

The statement I invoke at client side is
java -cp .;C:\JBossAS-stable\jboss-4.0.2_1\client\jbossall-client.jar;jndi.properties -Djava.security.policy=client.policy -Djava.security.manager=java.rmi.RMISecurityManager -Djava.rmi.server.codebase=http://sinfonix:8083/ client.DynamicClient

The client.policy file contains:
grant{
//permission java.net.SocketPermission "*:1024-", "accept, connect";
//permission java.io.FilePermission "${/}dynamicloading${/}-", "read";
permission java.security.AllPermission;
};

I first tried the first 2 statements but since I'm not sure what to put as java.io.FilePermission I replaced it with the AllPermission.

My jndi.properties file contains:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=jnp://sinfonix:1099

When I call the previous mentionned start-up command and when I enable logging. I get the following message (truncated);
FINE: main: name = "java.rmi.dgc.VMID", codebase = "http://SINFONIX:8083/", defaultLoader = sun.misc.Launcher$AppClassLoader@169e11

Exception in thread "main" java.lang.NoClassDefFoundError: ejb/DynamicLoadingRemoteHome
at client.DynamicClient.(DynamicClient.java:30)
at client.DynamicClient.main(DynamicClient.java:48)

My enterprise application is deployed as an EAR file which contains nothing more than a stateless session bean with one method returning a String. (HelloWorld like example).

Any help or advise would be greatly appreciated !!! Thank you very much.
