I personnaly looked at OracleAS and Java presentations, and especially the one regarding SOA, performances, security and web Services:
Some other presentations that I would like to read/see:
- Java EE/Java SE/Java Authorization Contract for Containers (JACC) Security in a Nutshell
- A New Approach to Diagnosing Java Application Performance
- Next-Generation Web Services Infrastructure and Interoperability
- Performance Management for SOA Applications
and I will take more time do read some others...
