● Security optimization (WS-SecureConversation)● Establish shared context on multi-message
exchange● Use context to generate derived keys on
subsequent msgs● Increases security and performance

before transport● WS-Trust
● Establish and broker trust relationships● Issuing, renewing, validating security tokens used
by WS-Security

WSIT Programming Model
● No runtime APIs for Tango● Developer writes consumers/providers via
JAX-WS and EJB APIs● Developer/deployer supplies config file to
enable/control Tango components● Config file written by hand or produced by
Tango NetBeans module

Implications for Java Developers
● Sun has worked hard to minimize impact (if any) on existing API's e.g. JAX-WS & JAX-B
● Enterprise developers (JavaEE) will see no changes in their programming model
● Interoperability with WCF should be achievable with minimal pain
● Performance issues are being looked at very closely and the relationship between Fast Infoset, TCP-bindings & Project Tango is getting particular attention
