Hi,
not sure of the best place to ask this one. Anyway, I've got a servlet
(running on Apache, with JServ 1.0 for what it matters) doing DB
accesses, and some of these accesses take a while to complete. I want to
give the user feedback while the DB query is being performed - something
along the lines of
'Awaiting query results. Please wait ...'
and then when the results are returned, repopulate the same frame with
the results. I've heard that I can do this with MIME, by setting the
ContentType to 'multipart/mixed', and sending several 'parts', but cant
get it to work properly.
For example, if I do
response.setContentType("multipart/mixed;boundary=my_identifier");
ServletOutputStream out=response.getOutputStream();
out.println("--my_identifier");
out.println("Content-Type: text/html\r");
out.println("\r");
out.println("Awaiting query results, please wait ...");
out.flush();
<... perform DB query ...>
out.println(--my_identifier");
out.println("Content-Type: text/html\r");
out.println("\r");
<... DB results ...>
out.println("--my_identifier--");
out.flush();
But I get the whole text including the MIME separators displayed by the
browser (Netscape 4.*). Has anyone got a working example ?, or a
reference I can look at ?
TIA
