Re: Problems using Axis on i5/iSeries/AS400/whatever they call it these days
Thanks for this info. It turns out that another copy of axis.jar (from an older project) was in the /QIBM/UserData/Java400/ext directory, so the classloading was all wonky, just as you describe. Once I removed the axis.jar file from there, I was able to fire Axis up in Tomcat on the i5. Runs like a champ. Jon Brisbin NPC International, Inc.

Jon, NoClassDefFoundError is a linkage error.
