DD vendor specific
posted 14 years ago
Just wanted to know why the DD are specific to each vendor. Is there any common way to write a DD which will be not vendor specific?

DD are vendor specific because the EJB container is implemented in different ways. Some (or every )containers provide extra features other than the one specfied in the spec.
Having a common DD would be difficult to achieve. As EJB evolves you will find more vendor specific feature becoming a standard and will fins its place in ejb-jar.xml. for e.g. EJBQL .
If you have a common DD it will be difficult for vendors to compete.

If everything is predefined and regulated by the spec,then the vendors will have a tough time to push their products as every other product will be the same
