errore: java.lang.reflect.invocationtarget

[francio21]

salve, ho creato un'applicazione java con eclipse, questa funziona sia se la lancio da eclipse si esternamente, ora voglio integrarla in una pagina html, ma mi da questo errore:

java.lang.reflect.invocationtarget

come posso risolverlo??????

Grazie anticipatamente

Un po più di dettagli non sarebbe male

estraggo il tutto salvandolo in jar:CreaOnto.jar
e questo è il codice html:
