Access EJBs via Applet
peterweik May 18, 2005 7:21 AMHello,
I have created one Session Bean with the Busines Logic and a Remote interface and three CMP - EntityBeans which are used by the SessionBean. Everything (Creating, Updating, EJB-QL..)works fine with a servlet or a normal Java Client. Now I have written an applet and the following error occurs:
"access denied (java.lang.RuntimePermission org.jboss.security.SecurityAssociation.getPrincipalInfo)..."
The Web Container is Tomcat 5.5, I have Created a Subdirectory which is called "applets", inside this dir are (hopefully)all the needed classes (the EJB Classes and Interfaces, the unpacked Jbossall-client.jar and a Class which is used by the applet class. The important Code looks like this.
public void initJNDI() throws
NamingException,RemoteException,CreateException{
try{
System.out.println("In initJNDI");
java.util.Properties p = new java.util.Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL,
"odyseus:1099");
//p.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
System.out.println("In initJNDI vor InitialContext(p)");
Context ctx = new InitialContext(p);
System.out.println("In initJNDI vor lookUp()");
Object o = ctx.lookup("PMBusinessLogicHomeRemote");
System.out.println("In initJNDI nach lookUp()");
PMBusinessLogicHomeRemote home = (PMBusinessLogicHomeRemote)PortableRemoteObject.narrow(o, PMBusinessLogicHomeRemote.class);
System.out.println("In initJNDI nach PMBusinessLogicHomeRemote home =..");//This output is show in the java console
pmBusinessLogic = home.create();
}catch(Exception e){
System.out.println("Fehler: " + e.getMessage());
}
}
This is the whole output in the console:
In initJNDI
In initJNDI vor InitialContext(p)
In initJNDI vor lookUp()
In initJNDI nach lookUp()
In initJNDI nach PMBusinessLogicHomeRemote home =..
Fehler: access denied (java.lang.RuntimePermission org.jboss.security.SecurityAssociation.getPrincipalInfo)
null
If I run this in teh appletviewer, then there is no problem.
I would appreciate help very much.
Thanks,
Peter
