Mark, can you give me some suggestions, to handle the problem. thanks, bhuvan.
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. Mark
------------------------------------------ Do you get that access denied error when you run your app outside the jar file? ------------------------------------------ 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.

Mark, any comments on --1.-- this approch. can i submit with this approch? any idea. regards, 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. Mark

facing one last problem. i am trying to upload my assign. but getting message that i have no right to upload. i have appeared in essay exam few hrs. back. perhaps that's the reason. i have written to sun and waiting response from last 3 hrs. thanks all of you to share your experience and knowledge. I don't know, what will be the result? want to say one thing, Mark, thanks for you help. regards, bhuvan.
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. Mark
