Hi,
ok, since feebdack on this one doesnt seem to work out and i only
found fragments of a functionality i was sure that is in the current
release of openJPA, i found out that FilterListener was just dropped
out in terms of features (it was there when this product was called
Kodo).
There "was" a documentation regarding all this which you can see here:
http://people.apache.org/~mprudhom/openjpa/site/openjpa-project/manual/ref_guide_enterprise_queryext.html#ref_guide_enterprise_queryext_jdoql
But as it seems, nobody cared so far to implement this in the
current JPQL parser. And thats where the fun starts because i always
thought that a Kodo->OpenJPA migration is a no brainer. Its really
sad because the backend site of this feature (Filter Extensions)
should be there and only because the JPQL parser (compared to the
JDO Parser back in Kodo) does only understand the default JPA spec
grammar, its left out.
IMO this was a brilliant feature of Kodo. So this a hughe step
backwards.... I will checkout if MethodQL helps me somehow.
Interessting that noone (especial no Kodo user) ever mentioned this
in the list. Cant be that i am the only one using some more advanced
Query features of Kodo.

Hi,
unfortunately i got no response on my last thread:
http://n2.nabble.com/docs-concerning-FilterListener-and-other-extension-points-td2386615.html#a2387075
Is there nobody who can help me out with FilterListener aka custom
Functions in JPQL ? There is definitely no docs on them and no
discussions at all....
I have a query which looks like this:
Query query = em.createQuery("select d from DP_PLZ_DA d where
" +
"(d.plz = ?1 and lower(d.oname24) = ?2) or (d.plz = ?1 and
d.oname24.ext:soundex(?3))")
the soundex() function is my custom FilterListener but no matter
how i try to call this custom function, the JPQL Parser just jumps
into my head and complaining about the JPQL syntax.
Is there anyone on this planet who knows how to trigger custom
functions like these?
A little bit scaring is that there is almost no community support
on OpenJPA. Is IBM the only using it? :-)
