[Java] Bild aus dem Internet

Ich habe ein kleines Java Programm geschrieben. Das mit dem Bildern aus dem Internet holen geht schon, allerdings nicht wenn man die URL per TextFeld angibt.

Hie erstmal mein Code:

Lass dir doch mal die URL in der zeigeBild nochmal auf der Standardausgabe ausgeben. Ich tippe mal, dass da irgendwas schiefläuft, wenn es ansonsten geht (url per Hand eingeben geht ja offenbar wie du sagst).

Das hatte ic hschon, die generierte URL ist korrekt!
