Problem with gpg --batch --gen-key

[Björn Mayer]

  Hi folks,

  I am trying to generate a key from within a Java application. Everything seems to go right,
  but at the beginning, everything stops. I have no idea what could be wrong...
  Anyone of you guys?

C:\>gpg --batch --gen-key
Key-Type: DSA
Key-Length: 1024
Subkey-Type: ELG-E
Subkey-Length: 1024
Name-Real: qwertz

Passphrase: password
%pubring C:\gpg\pubring.pgp
