Subject Re: Using XDoclet to generate openejb-jar.xml
Date Tue, 21 Aug 2007 13:01:11 GMT
Hi Shiva,

Thanks for pointing me in the direction of those discussions, I hadn't 
seen them on previous searches. The work I've currently done is an 
XDoclet plugin, and therefore is using XDoclet style annotations at the 

I haven't personally done much with EJB3, and hence haven't really had 
much need to use the new JSR-175 annotations, but I certainly think its 
right to consider providing a solution using those as well. I'm quite 
happy to work on something to use JSR-175 annotations too - I'm not sure 
how much overlap it'll have with what I've already done, but I think it 
might have some overlap with the work you've already done with the plan 
generation wizard.

Currently I only have one Geronimo specific annotation in my XDoclet 
plugin, and I'll need a few more, but largely I've used the standard EJB 
annotations. Presumably the same would apply using JSR-175 annotations, 
but providing Geronimo specific annotations might mean that apps might 
break on other app servers (or could developers get away with including 
a small jar file with the Geronimo annotations in their ear files)?

One other thing - I've logged this as a JIRA issue - is this necessary / 
should it be assigned to me, or anything like that?
