hi,

    you don't required to change in the weblogic-xml file, only thing
you have to do is call reference of session bean (whatever)in your
method implementation, that's it. Ofcoarse, you  can ready depended
beans reference in the weblogic -xml file,by specifing <ebj-ref> ejb
name</ejb-ref> , provided they( all the depended beans) are in the same
deployment descriptor.
