SQL query Executor factory not registered.

[rehansiddiquii]

Please help me to register the sql query exceutor in netbeans and java. I am using ireport 5.5.1 and netbeans 8.0 with jdk 8. The problem is that when i run the reports within netbeans, they run but when i build the project and run it from a jar file, report give the exception of this sql query executor. How to do it? Documentation asks to change the property but i couldn't do it, and i didn;t find any good tutorial on this anywhere.
