sende fra form til pdf udvikler

Jeg har 3 klasser.
Main: starter en gui klasse op.
asd: indeholder en textarea og en submit button
FormTextField: udskriver en pdf fil

Indtil videre har jeg manipuleret det således at den starter op. trykker submit, og så laves der en pdf fil.
Men, Den pdf fil der laves, bliver lavet ud fra forudbestemt string værdi "hej".

Det jeg gerne vil, er at værdien fra textarea fra klassen asd bliver sendt over, og bliver udskret istedet for. Men har problemer med at gøre dette. Regner med at man skal kalde variablen som den ligger i, istedet for at have en string værdi. men hvordan..

her er koden:
