To tell backgrounds of this:
Currently I have like this:
Action: create Collection from SQL
jx-Generator: create XML from that collection
transformer: sort result and do it HTML
serializer.
Problem is that if result is very very big, then Collection is very
very big. So solution could be like:
Action: generate SQL-query and sort it and just generate iterator for it
JX-generator: create XML from that iterator (forEach
select="iterator.hasnext())")
transformer: xml -> html
serialize
problem is that that iterator needs to be inside transaction (begin/
commit) to work.
And of course I want to make XML to flow well, so I can't just do
blocking operation and I want to keep levels simple so that I don't
want to mix sql + xml together.. I could do that commit in jx-
generator, but then it would not just be template for data.
Maybe patch serializer to do like:
<map:serialize>
<map:act type="foo" />
</map:serilalize>
<!-- this is never executed -->
or <map:act type="foo" execute="documentStart|documentEnd" />
Thanks, Joose

Hi again,
I tested this and seems like that execution of pipeline stops at
serializer,
so where to place that action to do sql:commit thing or do I have
to create CommitTransformer which just waits for endDocument?
Thanks,
Joose

Hi,
is there a way to configure action to happen after XML-document is
fully passed that action?
basicly like this:
1. sql:begin
2. generator
3. transformer
4. serializer
and generator needs to be in transaction to be able to generate
XML.. so I can't place sql:commit between 2 and 3 right? how about
if I place it after serializer, is it executed when document is
fully processed?
or if I can define that execute this action after endDocument sax-
event, then I can place it after 2 and 3, but it might be little
bit unlogical, right?
Thanks, Joose
