Hi Josef,
Thank you so much for your valuable response.
Yes, i am also thinking that if i am not able to resolve the dns, i will
use the ip address.
But i want to know is there a way that we can tell axis client to not
resolve the ip address on the current host and send the packet as is to the
proxy server. Once it is on the proxy server, proxy will take care of the
same right.
Is there any location where i can find some sample code for axis 2 clients
[over ssl layer]. Currently i am using axis 1.4 jars. Please let me know
which version is better one.
Also i want to know whether axis 1.4 supports proxy settings like
https.proxyHost and https.proxyPort etc.
Thanks,
Thomas
