Hi,
Sorry if this topic has already been discussed but I can't find it anywhere in
the archive. So here goes. I am VERY new to the xmlBlaster API and as such I
think this will be more of a user error then anything else but never hurts to
ask for someone to point out your own stupidity.
xmlBlaster (version 1.1.1 2006-01-16)
Ok question 1. I have a callback function and on initialization / connect I
pass the function pointer of my callback to the framework. Now all that goes
smoothly and a connection is established however the callback function seems to
get called only once for the first message that arrives into my subscribed
queue. I thought at first it was some memory exception that I was doing with in
my own function so I just changed the callback function to look something like
this:
bool xmlBlasterCallback(MsgUnitArr *msgUnitArr, void *userData,
XmlBlasterException *xmlBlasterException)
{
printf(“callBack called!”);
return true;
}
But to my horror it still only gets executed only once. Where can I look to
start diagnosing this problem?
Whew now on to question 2.
The xa->get function seems to have a few problems (between the chair and the
monitor):
- it keeps returning the same message over and over again unless I delete it
from the queue. Do I really have to do this? I would of thought that it would
make more sense to move on to the next message in the queue as the original
message has been consumed by my client.
Any help with these two things would be greatly appreciated. Also just as a
side note I have tried compiling the cpp api however the last step (linking)
fails. I have read the instructions about xerce link problems but am unable to
resolve it have there been any other reports of potential link problems using
VC2005? (i get 45 link errors all of them seem to be xerce related).
Cheers,
lr
