I have created a new project from the scratch and with that project the resource-folder is scanned properly. However, one thing I had overseen: When starting Eclipse (Helios), JBT asks me "to add JSF capabilities" to my project. I add it and sometimes when starting again it asks me again. So I guess: Resources folder "/resources/myComp" is missing in a project root directory is comming from that fact that JSF capilities was removed without notice it. However, now it seems to work.
