Hi,
I wanted to know whether I could develop J2ME programs and run them on a Nokia 9210 communicator. If so then what is the process of porting the KVM to the phone and running my programs on it???
Pls respond ASAP.

Hi,
I am using RMI over IIOP ina commercial project and I am using tnameserv as the naming server as usual.
Is it allright to use this in a commercial application. I may have upto 100 concurrent users making method calls on the RMI server. Will the server handle this efficiently!!!
Please do reply back urgently.

Dear all,
Thanks for your response but as suggested by David I alwaiys start the server with the -D java.rmi.codebase property which holds the URL where my Stub is.
Yet now if I remove the RemoteInterface from the directory where my client is (on a separate machine) I am not able to compile the client and it still gives me an error in the line where I cast the remote reference to the RemoteInterface. It says "class 'remoteinterface not found' ".
Please throw some more light o this as I also believe that the remote interface should not be present with the client and should be reference remotely through the stub but my client fails to compile if I dont include it in the Client's directory.
Pls reply to me urgently!!!

Hi all,
Pls do let me know if there are any ways to reduce the time for an RMI -IIOP call. Are there any methods following which I could reduce the response time of the remote method call. In my application the RMIClient takes a lot of time in Initializing the Context.
Thanks and Regards

Hi,
I have tried removing the Remote Interface from the client machine but the code did not compile giving me the error "myInterface class not found" in the line when i cast to it using PortableRemoteObject.
Pls help if I am wrong somewhere.
I have bounded the remote object as ;
MyImplementation abc=new MyImplementation()
also i am casting in the following way;
MyInterface xyz=(MyInterface)PortableRemoteOPbject.narrow(objref,MyInterface.class);
Please e know as to why am i not able to compile the Client without having the remote interface on its side.
Thanks and Regards

hi,
In my rmi-iiop call to a remote server I have placed the stb class and the Remote interface class along with the client and I am able to complete the call successfully.
my question is that do I really need to place the remote interface with the client and Stb classes.
If I try to remove the remote interface from the client directory then it gives me an error saying that "Remote Interface is not found.
I thought that the remote interface need not be with the client and the stb class.
please clarufy on this if I am wrong i.e. do i really need the remote interface with the client in order to make the rmi-iiop call.
Thanks and regards

Hi,
I have compiled the servlet and it is in the package "stocktr".
I have made the following changes to the weblogic.properties file:
weblogic.httpd.register.UserRegistration_Servlet=stocktr.UserRegistration_Servlet
And I have placed the servlet in the directory: E:/weblogic/myserver/servletclasses/stocktr/UserRegistration_Servlet.class
The HTML page which is calling the servlet is in the directory : ../public_html/reg.html
The ACTION tag has the following attribute : "stocktr.UserRegistration_Servlet"
I am getting Error 404 when i press the submit button.
Please let me know where am i wrong and what do i need to do urgently.
Thanks
