The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Signed Applet questions

Asked by KeithEJohnson in Java Programming Language

Tags: access, denied, what

Hi,
I need to create an applet that will print to a local printer. From what I have read I need a signed applet. I have managed to get a signed applet to work to allow me to write a file to my pc, but when attemting to read a file via FileInputStream I get:
Error: java.security.AccessControlException: access denied (java.io.FilePermission c:\Ticket.txt read)

The code I'm using is:
FileInputStream fis = new FileInputStream("c:\\Ticket.txt");
printStatus( new DataInputStream(fis).readLine());
fis.close();

I added this to my java.policy file:
grant signedBy "mySigner" {
permission java.io.FilePermission "C:\Ticket.txt", "read";
};

I read somewhere that FileInputStream should not be used when reading from the client but don't know what else to use.

Right now, I'm simply trying to read a text file and send it to the printer. What I ultimately would like to do is send a stream of text directly to the printer without a file. I'm completely new to Java so I've been doing lots of reading online to see that some people have been able to do similar things but have yet to find any good material to point me in the right direction.

If anyone has any information that can point me in the right direction I would greatly appreciate it.

Thanks,
Keith
