Printing JasperReport From Applet
I have developed web application which uses JasperReports
for reporting purpose.
In that I have to use Applet to View report at Client side. I can see report in applet normally , but when it comes to printing (when i clicked on Print Button in Viewer), it throws an Exception which I can see in Java Console. I surfed lots of about this Problem and did whatever which are suggested by experts on the net. I added the grant permission in catalina.policy
file as I uses the Tomcat
as my web server. Also, added grant permission to my applet as a codebase in java.policy
file. I signed the jar file which has class file for an Applet. But I still getting the same error.
below is the stack trace from Java console .

In order to allow an applet to print you need to sign the applet:
