Hi all,
I realized a project, I succssfully deployed it.

I don't know how to write a client to test if the process I deployed works fine.

I tried by modify the ones I find with jboss examples but I got client-side errors. The error is

[junit] 16:22:22,943 WARN JSR109ClientMetaDataBuilder : Cannot obtain the SEI mapping for: {http://esempio/jaws}Login
