Maintenance in a Service-Object

Hi *.*

I have got the following problem or situation:

I have one class for miscellaneous SOAP-services doing SQL-calls.
This class has got the scope of "Application", declared in the
SOAP-deploydescriptor.
Some of the sql-calls give back unpredictable huge resultsets, so I was
forced to block those
and give them to a client by using a selfbuilt mechanism.
That means, that a client gets a quest-handle by the first call and polls
the resultset blockwise by passing the handle
back again to a certain service.

My possible trouble is that it could happen that memory is  not  set free,
if a client crashes or a user kills the
client while it was polling such a blocked resultset.
My idea is to look up the quests, which are held by the server within a
HashMap, by a cycle and watch if they have been accessed
during a certain period of time. Therefore timestamps are also to be
recognised.
My question here is whether  it is possible or allowed to start
Timer-objects in such a SOAP-service-class, which scope is "Application".
Or is this not a correct solution?

looking ahead for an advice

Malte

Have you tried posting to axis-user@xxxxxxxxxxxxx?

I am never getting a response back.  My application just "hangs" for a
loooong time.  Hours.  If I leave it overnight, I come back the next day to
an IO exception stating that the connection timed-out.  I have confirmed
that the remote server is receiving my request, that it is properly
formatted, AND that the response is being sent to me.  My feeling is that
the remote server is setting the content-length of the message incorrectly
(too large for content of the response), and my code just ends up waiting
for
"the rest of the message" that doesn't exist
>     My problem is that I do not understand the content-lenght field, or
rather, what all it includes.  The response that I am getting from the
remote server is below.  Can anyone tell from the message itself if the
content-lenght is set correctly?   The server admin says that he includes
all
leading spaces (to accomplish the indenting/formatting) in the count for the
content length, as well as the cr/lf at the end of each line.  I would have
assumed that this should not be included.
