cxf-client: how to use a fresh http connection for multiple soap calls

[ss_eng2000 <ss...@gmail.com>]

Hi,

I am using a generated java cxf-client to make multiple soap calls to a soap
server. This is done in the same thread. I'm running into an error where the
second soap call made on a keepAlive http connection always fails. It looks
like cxf is using the same underlying http connection to make the multiple
calls within the same thread. Is that to be expected? How can I make my
cxf-client create a fresh http connection for each soap call? 

If I configure the soap server to not use the keepAlive connection, sending
of multiple soap calls work. I do not want to launch this way. I also
experimented with creating the javax.xml.ws.Service every time I need to
create a send a soap request. That still results in the same error on the
second soap request.

Note: this works on my personal environment (macosx 10.6.8) and not in other
linux environments. 

thanks.
