為了簡報,上網找了有關J2EE與.NET比較的資料,以下是來自 Sosnoski Software Solutions, Inc.的重點摘錄:
- J2EE Advantages
- Stability
- Platform evolved over last several years
- Changes coordinated through JCP
- Hundreds of companies and individuals involved
- Public discussion before standards become final
- Portability
- Based on standards, not on implementations
- Choice of vendors for price/performance/support
- Vendor extensions optional, but available for use
- Runs on everything from handhelds to mainframes
- Flexibility to change to new hardware or OS at any time
- Reliability, robustness, scalability
- Individual servers can be much more powerful
- Most servers include full clustering support
- EJB architecture designed for distributed use
- Transactions and security built in from the ground up
- Stability
- .NET Risks
- Security
- Despite PR campaigns, a major Windows drawback
- .NET better than prior frameworks (DNA, DCOM, ActiveX, etc.), but still based on Windows
- Immaturity
- Version 1.0 issues, likely to change in future (已經1.1了 ,應該較好了?)
- Language changes for developers new to .NET
- Application migration to .NET costly
- Not enough real world use yet to evaluate
- Vendor lock-in
- Always and forever, Microsoft owns you!
- License terms may change at any time (including with vulnerability fixes and service packs)
- Prices continuously increasing
- Future direction determined by Microsoft. Period.
- Security
