Specifying Different EJB Specifications
Problem
You need to change the EJB specification used when generating EJB files.
Solution
Change the ejbdoclet attribute
ejbspec to “1.1”
or “2.0”.
Discussion
By default, the current version of the ejbdoclet
task creates files based on the 2.0 version of the EJB specification.
If you need to change this to an earlier version of the EJB
specification, simply change the ejbdoclet
attribute ejbspec. Here’s an
example:
<ejbdoclet
ejbspec="1.1"
destdir="${dir.generated.src}"
force="${force.generation}">
<!-- all subtasks left out for brevity -->
</ejbdoclet>Tip
The only supported EJB specifications are 1.1 and 2.0.
If your project must run on 1.1 and 2.0-compliant servers, the build process can emit multiple versions of the application, one for each specification.
