Hi all,
I resolved. I start all again, I download jbossws-native and jbossas 5.1.0 and I follow de install intructions to install jbossws at jbossas 5.1.0
Then in my project (working with netbeans 6.8, jdk 6) only import the jar to compile, in my case jbossws-native-core for the cast
((StubExt) port).setConfigName("Standard WSSecurity Client");
thanks for the answers,
if someone has some problems with wssecurity, write me or post it.
