Problem using external jar

[thutyx]

  I know that this is a comun topic but i couldn find in the forum an old discussion about this.

I have a package in my proyect that i need to export in a jar file.

i added the jar in the ireport designer .. tools -> options ->classpath -> addJar

but now, i cant see my jar in the list of parameter class. So i write the name of the package, but at the moment of compile te .jrxml, guess wath.. ERROR!!!

it says:
