[Java] J2EE Vs. .NET

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
• .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.
