meaning of Deployers binding role

[Prashu Negu]

I dont understand *Binding* responsibilty of Deployer. For example whats the meaning of "The Deployer BINDS the EJB references to the enterprise bean homes in the target operational environment."

<ejb-ref>
<ejb-ref-name>ejb/EmplRecord</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>com.wombat.empl.EmployeeRecordHome</home>
<remote>com.wombat.empl.EmployeeRecord</remote>
<ejb-link>EmployeeRecord</ejb-link>
</ejb-ref>

If this is specified in DD, then it is automatically binded and this is done by Bean Provider and Assembler. Then, whats Deployer binds?

Thanks,
Prashant

Deployer is an expert for deploying the EAR file to the corresponding container. He knows something that the developers and assemblers do not know, e.g. connection factory references, container specific setting, etc.

For more detail, you could refer to HF EJB page 618.
