What line is throwing the exception? I am guessing that either the driver or the database file is not available.

No Database file and Driver Are Already Placed and Done All Thing's Perfectly Iam Sure

Then presumably you already know the answer to your question.

Based on your other reply you presumably already know all of the following so this is only in case someone else needs to understand it.
MS Access if a file system based database. That means that the database file must be accessible on the client machine for it to work.
That makes it very ill suited for anything related to internet/network work - such as using in in an applet. Additionally it might be less that well suited for multi-user use which also eliminates browser solutions (which are typically only useful for multi-user situations.)
As for the access problem - that couldn't be clearer - it is a access problem. Such problems can arise in any number of ways and the solution is always the same. And googling will find the same solutions which is normally one of the following.
1. Modify the access rights on the client machine to allow it. It is NOT possible to do this in the browser via java.
2. Sign the jar that has the applet in it.

I suspect that you are using Java rather than Netbeans, but your question makes no sense. You display things in Java by using some code, using either swing commands or System.out.print().
One of these days I'm going to think of a really clever signature.

thank you for reply back..yes im using java. jsp as my front page and java as class...
|
|
|
|

Then please edit your original question and explain what part of your code is not working.

When I suggested that you put some more detail into your question I meant more than just changing the word "Netbeans" to "jsp and java class". This question gives no idea what you are trying to do, where these values come, from or where you are trying to display them.

Hi family, i want to make project game by java, can you introduce me!, and what are the documents necessarily for GAME-java?, thanks you 
|

my long lost brother!
What kind of "game" do you want to create?
I suggest to make up some requirements. Write them down.

You can look through all the samples here[^], or for a specific sample see Sudoku Game in Java[^].

Hello,
I looking to develop a cloud storage service, and I need help on how to approach this, I already have setup apache tomcat and cxf acting as servers. I need to develop a service similar to amazon s3, where client's files are backed up on the servers.
The files are also need to be in sync with the servers and there is a clusters of servers and each need to have their own files in sync. I need to develop the server side web service and then a client to access these services, I'm quite new to web services, and need some tips on where to start and start developing these in java.
regards

I'm quite new to web services, and need some tips on where to start and start developing these in java.
Tip: start with a project that you can handle.
Bonus: Start with a project, which you've got the hardware for.
I doubt that you, as a beginner, are in charge of a multi server cluster system.

I done some research into using Restful web services and developing and I'm using tomcat to create cluster of servers, I was wondering how can I include a database on each server which are also in sync with the other servers, I have research into amazon s3 and they use NoSQL, I need to get somthing like this to work on each server containing user login, and other information such as files(files they uploaded) metadata. this is part of my uni work

Your post is very confusing.
I suspect because you are not only new to web services but also everything associated with server processing.
I suggest that you FIRST do research about what technologies and architectures are involved in and used with business servers. Do not attempt make any decisions about technologies until you have a better understanding of the different stategies for implementing things.
Then SECOND you make a decision about architecture and decision based on the needs of the business. Naturally if you do not understand the needs of the business then you will need to learn that first.

Well, it is quite possible but you need to do a bit of research first: something like this[^].

A law firm handles cases of two categories I.e. either minor or major. Each and every case is assigned a lawyer. The case is either open or closed. Before a case is closed, the lawyer can either win it or lose. For each case, the client should pay an amount that should be set by the law firm. The amount paid for a minor case costs the client ¾ of the amount for major cases. If a case is lost, the firm reduces the client’s pay by 10% the price for a major case. The firm is trying to evaluate the lawyers’ performance through the following criteria.
1. For every major case assigned, the lawyer gets 3 points
2. For every minor case assigned, the lawyer gets 5 points
3. For every case lost, the lawyer loses 4 points
4. For every case won. The lawyer gains 4 points
Write a java program that will enable the firm to enter the amount of money clients are supposed to pay for the major cases. The system should enable the firm to register lawyers, register new cases, register clients, close the cases that are either won or lost, and assign lawyers to cases. The program should display the following on request
1. Show how many cases were lost and how many were won
2. The best and worst performing lawyer
3. Display the amount of money received from all the closed cases
4. For a given lawyer, how much money will was generated from all his closed cases
5. How much money the firm has lost through losing cases

Solution.
1. Learn the basics of programming.
2. Learn the basics of create a program to solve business requirements.
3. Write code based on the posted requirements.
4. Test the code and repeat 3 until the code works.
