first of all you cannot use two set filter parameter
qry2.setFilter("key == keyParam");
qry2.setFilter("initialVersion <= version");
this is invalid.
qry2.setFilter("key == keyParam && initialVersion <= version");
combine them in one like that
and you cannot use two declare paramether either.
here is an example
http://openimageserver.svn.sourceforge.net/viewvc/openimageserver/OpenImageServer/tags/0.2.94%20beta/src/ois/model/impl/ModelManagerImpl.java?revision=98&view=markup
in line 188 you can see the query you are looking for (in
getImageFileByName method)
