Ejb-ref errore when deploying a previously working ear on weblogic 8.1

Question

when deploying an ear module on weblogic 8.1 i get the following error:
The ejb-link 'CustomessagingBrick.jar/CustomMessaginBrick' declared in ejb-ref
or ejb-local-ref 'ejb/Service2' in the application module 'cmbrick.war' could
not be resolved. The target EJB for the ejb ref could not be found.
The ear is composed of two sub-modules:
CustomMessaginBrick.jar
cmbrick.war.
The same ear was deployed on weblogic 6.1.
Every reference in the ear seems in the right place so i am really clueless.
Hereafter i include the relevant portions of the deployment descriptors.
Thanks in advance!

the web.xml for cmbrick.war contains the following data:
<ejb-local-ref>
<ejb-ref-name>ejb/Service2</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home>com.hutchison3g.core.brick.custom.messaging.CustomMessagingBrickLocalHome</local-home>
<local>com.hutchison3g.core.brick.custom.messaging.CustomMessagingBrickLocal</local>
<ejb-link>CustomMessagingBrick</ejb-link>
</ejb-local-ref>
its weblogic.xml file is the following:
<?xml version="1.0" encoding="UTF-8"?>

while the weblogic-ejb-jar for CustomMessaging bricks contains the following:

The issue is that WLS 6.1 didn't really support ejb-links properly. An
ejb-link should allow you to link a webapp or an ejb to another EJB
without requiring additional information or a global JNDI name on the
target EJB.
WLS 8.1 is following your ejb-link and telling you there's not enough
information.
You have 2 options:
1) Remove the <ejb-link>...</ejb-link> from your web.xml. You'll be
using just an ejb-reference at that point, but you've already included
the necessary information in the weblogic.xml that we can locate the EJB
via its global jndi-name
or
2) Change the ejb-link to be
<ejb-link>CustomMessaginBrick.jar#CustomMessagingBrick</ejb-link>
If you wanted to, you could then remove the reference info from the
weblogic.xml
