Congratulations Ravikiran
Did you use the GUI to display application help?

[Ravikiran Choppalli]

Thank you Jane,
I've used HTMLEditorKit to show the User guide file and About box information. Both can be seen from the GUI. I've provided Menu bar on the top.
Thanks,
Ravi.

Congrats!!!
I'm just now starting and i'm not sure how to go about designing my lock/unlock strategy. Can you or anybody else reading this please give me some tips to get started.
Thanks!

CONGRATULATIONS!! Did you define any timeout for the record lock? If so,what is the value of timeout? How did you shutdown your server? Can I use Ctrl+c to shutdown the server? Thanks for your time.

I'm just now starting and i'm not sure how to go about designing my lock/unlock strategy. Can you or anybody else reading this please give me some tips to get started.
>>> The strategy I used is to hold the locks in a container. whenever you try to lock a particular record number, check whether it is already in the container, if so, wait until it is not there and then lock it. Same way, when you try to unlock a particular record, check whether that record number is in the container if so, unlock it and if not, don't do anything.
If the case is to lock the whole database, put some -1 in the container and check for that. Before locking just make sure that there is no element in the container.
GOOD LUCK then...

>>> No, I did'nt use any timeouts for the record locking. Make sure that you call your unlock (from client side) in the finally block so that even if your method fails due to any exception, you make sure that you unlock the record.
>>> Since I'm starting my server from a command line, I guess the only option to shutdown is using ctrl+c. This is how I used and I passed ;-) But if you are running on Unix, since it runs as a process, maybe you can write a shutdown script which checks for the process with particular name and kills it.
Thanks,

congrats on your success
help me on below mentions

2.what had you written in security policy file?
3.had you given HELP option in your gui.if so what had you mentioned in it.
4.what were the question ask to you in written exam?
thanks

Ravi,
You got 20/20 in Documentation. What all documents did you include? Did you provide System Design documentation, with architectural diagrams? Did you generate javadoc on private methods also? Thanks for your input.

[Ravikiran Choppalli]

Pooja,
Thanks for your wishes ...
Here are my inputs for your questions ...
congrats on your success
help me on below mentions
1.you use activation or unicast?
>>> My RemoteDataAdapter extends UnicastRemoteObject. If this is not the answer you were looking, please mention your question more clearly...
2.what had you written in security policy file?
>>> It really does'nt matter. I gave all permissions in the security policy file. This is all I had in both client and server policy files.
grant {
permission java.security.AllPermission;
};

3.had you given HELP option in your gui.if so what had you mentioned in it.
>>> Yes, I've given, as I said earlier using HTMLEditorKit showing in a JEditorPane. You can pass any HTML file and it will display. I gave the overall description about the application and all the functions you can carry out using the application, how you can invoke using keyboard keys, etc...
4.what were the question ask to you in written exam?
>>> These were more general. You will have plenty of time. Mostly about the Major design decisions like RMI Vs Serialized Objects, Extending Vs Modifying Data Class and Your Lock Unlock Strategy.
thanks

>>> I'm happy that I got 20/20 in documentation. Cos' I've put lot of effort to make all the documents very readable formatting the contents and editing the contents. Also, I've followed EXACTLY what was asked in the Instuctions.html to prepare the README.txt file. And for JavaDoc it was very simple. I was using KAWA IDE. I copied all the source files into one directory and ran JavaDoc command from the Kawa Ide. It created everything. I did'nt provide the Links to Java Classes like String etc... so I was sceptic whether I'll score cent on this part of the exam.... Finally I did ;-)
I've provided
1) Design Decisions Document.
2) Readme.txt
3) JavaDoc
4) User Guide Html ]
] - I was showing these from GUI.
5) About Box Html ]
Thanks,
- Ravi.

Luna,
Sorry I missed the part you asked. I did'nt use any Class diagrams or Architectural Diagrams. Actually I've reverse engineered those things from my application code using Togethersoft. I had to do lots of modifications etc. And as I thought it would consume more time, I just skipped it.

HELLO
AS SUGGESTED BY YOU <IHAVE USED EDITOR PANE ><BUT FACING FOLLWING PROBLEMS:>
(1)receiving html parser Exception.
(2)has this problem to do with editor kit.

thanks
pooja vij

[Ravikiran Choppalli]

Pooja,
You've to pass the html file to be shown in the editorpane in the following way :

JEditorPane editorPane = new JEditorPane();
String urlStr = "file:"
+ System.getProperty("user.dir")
+ System.getProperty("file.separator")
+ htmlFile ;

URL helpURL = new URL(urlStr);

editorPane.setPage(helpURL) ;
editorPane.setEditable(false);
Then you should add this editorpane to a scrollpane.
Hope this helps...
Thanks,
- Ravi.
