8. Security Patterns Easy: TLS + Web Server Users Improved: TLS + LDAP Users Best: SAML + STS (+TLS)

9. Java-based WS Platforms JAX-RPC: Axis2-based solutions (Axis2, WSO2, Geronimo etc) JAX-WS: Built-in web containers of web severs Glassfish and Tomcat

10. JAX-WS Approach Good: Part of integrated WS stack Sun Metro Tested on Glassfish and Tomcat Tightly integrated with Microsoft WCF Easy development Bad: Security implemented as NetBeans Plugin Not compatible with JAX-RPC

11. Axis2-based Solutions Good: Popular WS container Can work without any web browser Security implemented as Axis2 modules Has module for JAX-WS clients Bad: Cannot run JAX-WS applications If JAX-WS wins what to do with Axis2 applications?
