IFS HTML Preview

Question

hallo list,
i run Oracle 8.1.7.2, iFS 1.19 an solaris.
iFS fits our purpose quite good, but the customization is really a hard pain.
The only thing i wanna do is to make a HTML preview of the document, when it
is stored via smb or http and display it later via the container.jsp.
In the ifssys schema there is a table called ODM_DOCUMENTFILTER which sounds for
to fit with the ctx_doc.filter procedure.
So my idea was to create a trigger on the table ODMM_CONTENTSTORE (where are the
real documents stored) like
create or replace trigger TRG_ODMM_CONTENTSTORE
after insert on ODMM_CONTENTSTORE
for each row
begin
ctx_doc.filter('GLOBALINDEXEDBLOB_I', :new.ID, 'ODM_DOCUMENTFILTER', :new.ID, false);
end;
Unfortunatly this was not working.
But in the iFS API I found two methods under the Document Class
Document.filterContent() and Document.getFilteredContent().
So my Question is:
1. What can i do that above trigger is working?
2. If not, how can i implement the Document.filterConent() method in the existing parser
without writing a completly new one. The method only has to save the filtered data in the
table ODM_DOCUMENTFILTER.
3. Is there a workaround, which has solved already my tasks.
Thanx for your help.
