Could not instantiate Seam component: citiesHome

onuruysal May 8, 2011 9:36 AM

Hi All,

I've Installed Seam 2.2.1 working on JBoss 5.0.1. The core classes (login.java) which comes with seam works properly... But if i add new entity to my project, I'm getting some errors when i deploy.

Did you put *-ds.xml file with datasources configuration to your deploy folder?

see for example "server\default\deploy\hsqldb-ds.xml" file.
