wherein a first data tunnel is established between said first endpoint, through a first firewall, and with said web service gateway; wherein a second data tunnel is established between said second endpoint, through a second firewall, and with said web service gateway; and wherein said first endpoint communicates with said second endpoint through said first firewall, said web service gateway and said second firewall by way of said first tunnel and said second tunnel; and

wherein said web service gateway utilizes WS-Addressing header and other transport-dependent headers to store and extract service destination information.

8. The computer readable medium of claim 7 wherein said instructions for establishing data tunnels includes instructions for establishing at least one data tunnel between an endpoint and said web service gateway.

9. The computer readable medium of claim 7 wherein said instructions for establishing data tunnels includes instructions for initializing data tunnel establishment from said first endpoint to said web service gateway, and said second endpoint to said web service gateway.

10. The computer readable medium of claim 7 further comprising instructions wherein said web service gateway brokers web service messages comprising Simple Object Access Protocol (SOAP) messages between said first endpoint and said second endpoint.

11. The computer readable medium of claim 10 further comprising instructions for providing end-to-end message level security by placing security credentials in said SOAP messages.

12. The computer readable medium of claim 10 further comprising instructions wherein said SOAP message routing is performed using bi-directional next hop routing.

13. A web service gateway comprising:

a memory;

a processor;

a communications interface;

an interconnection mechanism coupling the memory, the processor and the communications interface; and

wherein the memory is encoded with an application providing two-way web service interaction crossing an enterprise domain, that when performed on the processor, provides a process for processing information, the process causing the web service gateway to system to perform the operations of:

establishing, by said web service gateway, data tunnels for directing web service requests and responses between a first endpoint, a second endpoint and said web service gateway, wherein said first endpoint is located in a different enterprise network than said second endpoint; and

maintaining a Service Local Registry at said web service gateway, said Service Local Registry exposing Web Service Description Language (WSDL) interfaces of said first endpoint and said second endpoint, and wherein both incoming and outgoing data packets are transmitted within an established tunnel, to allow said web service gateway to perform bi-directional routing;

wherein said first endpoint is a client and said second endpoint is a server, maintaining a Service Local Registry at said gateway, said Service Local Registry exposing Web Service Description Language (WSDL) interfaces of said first endpoint and said second endpoint, further comprises registering the interface of the client to make it visible for interaction with the server;

wherein a first data tunnel is established between said first endpoint, through a first firewall, and with said web service gateway; wherein a second data tunnel is established between said second endpoint, through a second firewall, and with said web service gateway; and wherein said first endpoint communicates with said second endpoint through said first firewall, said web service gateway and said second firewall by way of said first tunnel and said second tunnel; and

wherein said web service gateway utilizes WS-Addressing header and other transport-dependent headers to store and extract service destination information.
