I have a jython scrip which loops over a bunch of adde requests.
Some times this loop hangs up. (I need to go into the task manager and kill
java.exe to escape).
It looks like it stops when no data is avalable on the server to match the
request. I would have hoped for an exception or at least a time out. As you
can see the script has a try/except structure, but the adde: request just stops.
Is there some other way to indicate to the adde request to stop waiting if
the server never responds? Shouldn't the server send some message when there
is not possible data?
this is the particular request:
adde://suomi.ssec.wisc.edu/pointdata?group=cimssp&descr=wndgoesW&parm=lat lon di
r spd pw itim tlat tlon iday&select='TYPE IR; LAT 34.0 44.0;LON 67.0 87.0'&num=a
ll&pos=1
It is part of a larger script below
Thanks for any suggestions
