axis: unknown certificate

[Lady]

Hi ,
I am using axis 1.3 and J2EE 1.3 under websphere application server
5.0.2

I want to use MySocketFactory and JSSESocketFactory. This is because I
want to connect to a web service that uses self signed certificate and
to other that uses a CA certificate. When I connect to every client
independently I got the response from both web services, but when I
connect to both one after the other, I got an axis fault exception
caused by unknown certificate . I've notice that Axis always remember
the First Factory though I've set AxisProperties.setProperty(
"org.apache.axis.components.net.SecureSocketFactory",
JSSESocketFactory.class.getName ()).

Do you have any idea?

Thanks a lot
