I can run my applet but I am not able to create a PDF file from the input text area after a button click. I am using iTextPDF.

Wooooooah, could you do a little formatting? What are you trying to do? what code is causing the problem? Give us some meat here. — Olivier Poulin, Jul 07 '15 at 17:39
I can able to create applet and run, I have jtextArea to write the words or sentence from that I want to create pdf file by clicking button but some "AWT-EventQueue-2" java.security.AccessControlException: access denied ("java.io.FilePermission" "Report.pdf" "write") how to solve that II am using itextpdf to create applet — Sunil Bhagwat, Jul 07 '15 at 17:54
this looks like a file permission problem. Are you sure you have write permission on your pdf files? — Olivier Poulin, Jul 07 '15 at 18:00
In my applet creation program I have created jar file and In that program I am able to write the words via text area and can create pdf in folder named "Report.pdf" and I add that jar file in web application and run the web application to run the applet — Sunil Bhagwat, Jul 07 '15 at 18:07

I could able to sort out my problem by adding following codes to my C:\Program Files\Java\jre1.8.0_45\lib\security\java.policy

grant codeBase "http://localhost/-" {
 permission java.security.AllPermission;
 permission java.io.FilePermission "<<ALL FILES>>", "read";
 permission java.io.FilePermission "<<ALL FILES>>", "write";
};

An applet that requires access to the local file system on the client computer needs to be **digitally signed** using a valid code signing certificate. Editing policy files is something that will only work for the developer's machine. – Andrew Thompson Jul 08 '15 at 11:18
But how to be digitally signed using a valid code signing certificate – Sunil Bhagwat Jul 08 '15 at 17:25
That is too big a question to answer in a comment. – Andrew Thompson Jul 09 '15 at 00:54
any other resource for get it done. any example how to do that. – Sunil Bhagwat Jul 09 '15 at 09:37
