Hi, I have a long running problem that I cant seem to find an answer to, I am sure I have asked here before but I didn't get any replies.
I get an unknown host exception generated as a SOAP fault by axis, I can't see any reason for this although there is one thing that is unusual and I think it 'could' be the cause. The dns name I am trying to connect to is MHS-0 and it resolves to an IP address fine, however the IP address that is returned by a DNS query to MHS-0 is not MHS-0's IP address. MHS-0 is a load balancer and it returns the IP address of MHS-1 or MHS-2 dependant on load. I can ping, nslookup MHS-0 fine from the commandline and it always returns either MHS-1 or MHS-2's IP. I think that this is a java\axis problem only. I think that it could be that axis resolves MHS-0 to an IP address and sends a request, but the IP address that is returned is for MHS-1 or MHS-2 (dependant on load), if axis now attempted to perform a DNS on that IP address it would not resolve to MHS-0 now. Does anybody know any answers to this, or has anyone experienced anything similar? Would upgrading to the latest version of axis solve this? I am sorry if this is a basic description but I have a limited knowledge of networking and DNS etc. If anyone can help me it would be good as this has been ongoing for sometime now, and currently we have to get around this using a hack and mapping a host entry for MHS-0 to either MHS-1 or MHS-2 IP address (which means we have no load balancing).
