Real world comparisons of Glassfish and JBoss 5?

Question

Does anyone have experiences with both in the real world? How do they compare in terms of performance (memory usage, speed, etc)? Stability?

Does JBoss Seam work well

Answer 1

I will have to go with Glassfish on this. Deploying a diverse range of application built on different webservices, we had major compatibility issues, resulting in customizing the class loading & still faced many issues. Glassfish I never faced any such issues.
