[JBoss Getting Started Documentation] - Fibo tutorial interface package not generated, please help
by tmoore
Hi,
Thank you to anyone willing to help me. I am trying to work my way through the Fibo Tutorial and when I reach the part of Chapter 5 where I run the XDoclet, it seems to run ok but it does not create the interfaces package, or the files that the tutorial shows should be in them. I have tried starting over and going step by step but still get this problem.
I downloaded "JBossIDE-1.6.0.GA-Bundle-win32.zip" and extracted it to it's own directory and used it "as is" as a starting point for the tutorial. Is there something else that I needed to do? I have also downloaded and set up JBoss 4.0.5 and installed it using the JEMs installer and another tutorial. The JBoss server seems to be working.
There are several compilation errors in my Tutorial project, most of which look like they stem from the missing packages and files.
In addition to the compile errors for the missing classes, I also get the following errors listed under problems:
The content of element type "ejb-jar" must match "(description?,display-name?,small-icon?,large-icon?,enterprise-beans,relationships?,assembly-descriptor?,ejb-client-jar?)".
The content of element type "enterprise-beans" is incomplete, it must match "(session|entity|message-driven)+".
I don't know what information is usefull but, here are my ejb-jar.xml and jboss.xml files. If other information would be helpful, please let me know and I will post it.
