Follow the algorithm presented in the chapter to compile and run the Hello example on one machine. Write a report to describe your experience, including any difficulty you encountered and how you resolved it.

What will be an ideal response?

To start out with, these are the files in the Hello folder:
Directory of C:\mliu\tmp\hello1.4
09/09/01 02:33p 107 Hello.idl
07/31/02 09:12p 1,222 HelloClient.java
09/09/01 05:23p 774 HelloImpl.java
12/29/02 04:03p 1,891 HelloServer.java
07/31/02 09:19p 683 README
11/03/02 09:51p 63 runClient.bat
11/03/02 09:44p 38 runOrbd.bat
11/03/02 09:49p 65 runServer.bat

When the interface file is compiled as follows:
idlj -fall Hello.idl
The resulting directory is as follows:
09/09/01 02:33p 107 Hello.idl
02/26/03 09:48p

HelloApp
07/31/02 09:12p 1,222 HelloClient.java
09/09/01 05:23p 774 HelloImpl.java
12/29/02 04:03p 1,891 HelloServer.java
07/31/02 09:19p 683 README
11/03/02 09:51p 63 runClient.bat
11/03/02 09:44p 38 runOrbd.bat
11/03/02 09:49p 65 runServer.bat

The contents of the HelloApp directory is as follows:
02/26/03 09:48p 319 Hello.java
02/26/03 09:48p 1,893 HelloHelper.java
02/26/03 09:48p 775 HelloHolder.java
02/26/03 09:48p 313 HelloOperations.java
02/26/03 09:48p 2,133 HelloPOA.java
02/26/03 09:48p 2,382 _HelloStub.java

All the .java files are then compiledas follows:
javac *.java

when the runOrbd batch file is run, a console screen is opened and the following commands are shown:
start orbd -ORBInitialPort 1234
which in turn starts another console screen for the running of the orbd at port 1234.

The server is then started using the runServer batch file:
C:\mliu\tmp\hello1.4>runServer

C:\mliu\tmp\hello1.4>java HelloServer -ORBInitialHost localhost -ORBInitialPort
1234
HelloServer ready and waiting ...

A client can then be started using the runClient batch file, resulting in the following display:
C:\mliu\tmp\hello1.4>runClient
C:\mliu\tmp\hello1.4>java HelloClient -ORBInitialHost localhost -ORBInitialPort
1234
Obtained a handle on server object: HelloApp._HelloStub:IOR:00000000000000174944
