Hi all,

I am trying to run the one sample CORBA application , which HelloPersistent, from Here
I have all setup for running this app

but when i am trying to run the servertool for registering server , it hangs in and never responds

I used following command

servertool -ORBInitialPort 1050

(My ORBD is already running on port 1050)
then it gives me prompt and entered following command

servertool> register -server PersistentServer -applicationName s1
-classpath .

after this it hangs in and does not do anything

What could be wrong with this ??

This is what k&b says on page-289 of OCPJP6 book

from K&B book wrote:

Don’t spend time preparing for topics that are no longer on the exam!
In a nutshell, the Java 5 exam differs from the 1.4 exam by moving away from bits, and
towards the API. Many 1.4 topics related to operators have been removed from the exam,
so in this chapter you WON’T see
■ bit shifting operators
■ bitwise operators
■ two’s complement
■ divide by zero stuff
It’s not that these aren’t important topics, it’s just that they’re not on the
exam anymore, and we’re really focused on the exam.

Next time, Whenever you want to ask new question, start in new topic.

Second,answer to above question,Whenever the byte ,short and char type variables used in the expression like above one ,addition , those variables are promoted to int type

Compiling the file which is in package that requires class in the another package , you need to specify the classpath that is root of package directory
In this case, if you want compile class Test which is in directory,say. body/left/leg ,and this Test class requires another class i.e. TestHand, So you must specify classpath to TestHand for compiling the Test class + in Test class. you must specify package declaration .

Here is the program and command line invokation

Hope this helps

try using -classpath switch on javac command and in that set classpath as absolute path to your body folder

Have a small question where do reference variable at the class level gets stored ; for example

Hope i make sense ; thanks in advance


At line 12, you are creating the instance variable/field , Which is the reference variable, declaration and initialization ,of class MyClass
When you will create the instance of the ,then that instance will be stored on Heap memory along with all its instance variables/fields i.e. the state of the object

So, reference variable cL will be on heap as along as instance is on heap
and yes reference variable c2 which is declared inside method will be live as long as method code executes.

Hope this helps..

For reading the file line by line ,you have to use BufferedReader.readLine() method which returns next line text ,if it end of the file (Stream) it returns null
Following is the code for reading data from file
