JBOSS EAP 6.1.0.alpha - Could not find default constructor for class

[georgesg]

I keep getting the below "WARNING" during deployment. Am currently in the process of migrating web and EJB 2.1 applications from JBOSS 4.3 to JBOSS EAP 6.1.0.alpha.

Kindly  advise is the below error is serious and need to be fixed or can be ignored ?

[sfcoy]

It looks like your deployment contains both eclipse and apache cxf jars, which would not be right. Consider removing them.

[georgesg]

Thanks for the quick response stephen.

for the jetty error, when i decompiled the eclipse-jetty jar file, it actually don't have the default constructor. Attached is the java source for the Class which the exception is complaining.

[sfcoy]

The point is that I don't believe that you should have that jar in your deployment at all.

AFAIK it contains the Jetty Servlet container, which would be completely redundant.
