Marco,
Asides from the fact that the implementation needs changing so it still
builds under JDK 1.4 (see XDT-1526), why couldn't this just use the
existing merge handler? i.e. instead of using
<XDtJdoObjectIdGenerator:includeImports/> and
<XDtJdoObjectIdGenerator:includeBody/>
with corresponding
@jdo.create-objectid-class include-imports="somefile"
include-body="someotherfile"
tag parameters, why not use
<XDtMerge:merge file="jso-objectid-imports-{0}.xdt">
<XDtMerge:merge file="jso-objectid-body-{0}.xdt">
instead to include them as per-class merge files? This has the
advantage that the merge files can also include further <XDt...> tags
for processing.
Alternatively, if there is a good reason for handling the JDO include
files this way, perhaps it should make use of xdoclet.util.FileManager
like the merge handler does? That would also fix XDT-1526.
