not sure if AS 4.2.3 is supported but I found an issue when running the WSTrustClient on it. The issue is that when WSTrustClient calls:
nodes = ((Element)data).getElementsByTagName("RequestedSecurityToken");
Just to follow up on this issue...
I upgraded jbossws-native-core to version 3.0.5.GA and also jbossws-common to version 1.0.8.GA and things worked as expected.
