Hi Samisa,
I have now fixed this since this has become an urgent problem for us.
I want to load the channel libraries during Axis::initialize which is long
before the transport object gets created. But I didn't want to break the
encapsulation of the channel and transport. So I fixed it by adding a
preloadChannels C-style function which is exported from the transport
library. preloadChannels calls static ChannelFactory::preloadChannels to do
the actual loading. This is all called from
SOAPTransportFactory::initialize. So the ChannelFactory has these static
channel libraries loaded and shared across all threads and all stubs, and
other channel libraries which are specific to this instance of the
ChannelFactory/SOAPTransport so an application can still load a different
channel for a particular stub. This "loading a different channel for a
specific stub" is not function that IBM is interested in and it's not
tested but I've tried to ensure that I haven't broken it for whoever uses
it.
Please alter this implementation if you need to.
BTW I'm on holiday next week,
Mark

Hi Mark,
I too think that loading the channel multiple times is an
unnecessary
resource wasting task.
+1 to move this to Axis::initialize()
I am looking into the transport these days, and I hope I will
be able
to look into this as well (provided you haven't solved this already)
Thanks,
Samisa...
