Can't set up IP host by eclipse in project corba

[lanhlung696]

Please help me. My project to display like window explore from any client's ip address. If i used command line, i can set ip & post listen for server by code:
start java TestWEImplServer -ORBInitialPort 1050 -ORBInitialHost localhost
&
java TestWEImplClient -ORBInitialPort 1050 -ORBInitialHost localhost
but went i use eclipse 3.5. jdk 1.6 with plugin ORBStudio_7.7.7.jar for eclipse to run idl file. I don't know how to set ip address to display.
Please, help me as soon as you can.

Where do the programs TestWEImplServer & TestWEImplClient come from?

[lanhlung696]

Sorry, i mistake. Here is my code
file: assignment.idl

module TestCorba{
	struct FileInfo {
		string filePath;
		string fileName;
		boolean isDirectory;
	};
		typedef sequence<FileInfo> FileIf;
	interface TestWE{
		FileIf listRoot();
		FileIf listChild(in string path);
	};

};
