Well you seem to be moving one step at a time donw the fun road.
Do you get that access denied error when you run your app outside the jar file?
In any aspect of your local mode, do you have a SecurityManager? If you do, you will need a policy file, and start you client as such
java -Djava.security.policy=policy.all -jar client.jar
But I'd suggest removing the SecurityManager.

Without jar file, i always used
set classpth=d:\scjd\starting;
java suncertify.db.BindDataAccess (server side main file)
and never get any problem either in n/w or local mode.
problems start with the idea to run app. with jar file.
(which i am not able to use properly)

Same problem, AccessDenied while reading db.db file from server side also
after reading server side db.db
i register the server object. but never reach this point after using jar file to start the appl.
--1.-- app. works without jar with
java -djava.security.policy=mypolicy.java -classpath d:\scjd\suncertify suncertify.server.BindDataAccess
but restricion is user must have mypolicy.java file in the current directory.
otherwise user can run app. form any directory location with above command.
thanks,
bhuvan.

Just curious...why do you have to create an executable jar while you can set the CLASSPATH to include the jar file and execute the application with out -jar option?

What's really cool, is you can associate .jar files in Windows, so when you want to run the client in local mode, I only need to double click on the client.jar file in windows explorer and it runs.
Actually the reason why I like executable jars is that I try to keep the user from having to understand what classpath is. I know in the first year of Java programming classpath always got me really frustrated. Imagine a user who knows nothing about java.
I still get classpath issues, but when I see the errors at least I know right away where to look.

Nah, everyone gets that message. You need to send an e-mail to Monica at who2contact, and tell them you are uploading the assignment and get that message. They are pretty quick on that one to fix.
