We are having a problem with .NET clients being able to access our Web services. This problem has been traced to a problem with the version of Axis being usedin 4.0.1. Therefore we are looking to upgrade either to Jboss 4.2.3 or the most recent version of Glassfish.
The main reason we are considering Glassfish is because of the excellent, free support that the community provides. With very little effort I have been able to find multiple resources for help in migrating from Jboss to Glassfish. So far, I have not been able to find equivalent resources for aid in migrating from Jboss 4.0.1 to 4.2.3. I have been googling, on this Website and the WWW, topics such as upgrading Jboss and migrating applications to Jboss.
I'm still pretty much of a novice with application servers, so the amount of support I can get is going to be the deciding factor in which option I take. Can anybody here direct me to resources that would help me upgrade from 4.0.1 to 4.2.3? Any help would be appreciated.
There's isn't a definitive guide for migration. But you start looking at http://wiki.jboss.org/wiki/JBossReleaseNotes which has the change logs for various versions.
Then as and when you start running into errors (if any), while migrating, you can always post here in the forums.
