I installed JBossAS v4.2.2 with native WS version 2.0.1 SP2 (according to jmx-console). Can I now just download: jbossws-3.0.1-native-2.0.4GA an install it on my existing JBoss ? Are they compatible? How do I upgrade in detail? Why are there two version numbers ("3.0.1" and "2.0.4" embedded in the download archive name (see above) ) ? What is the real version of WS component?
