Maybe you get confused by the version.
JBoss AS7 == EAP6, the release numbers differer.
Since AS7/EAP6 there is no longer a twiddle tool.
Use the latest versions and try AS7/EAP6 as server integration
Hi Wolf-Dieter sorry for my late reply and thank you for your answer,
finally I downloaded Eclipse Luna and I still used jboss-eap-6.2 and had no longer the twiddle tool error
