2. Does Apple support Just-in-Time (JIT) compilation with WebObjects 4.5?

Question 1: What JDK version is used in WebObjects 4.5?

Answer : WebObjects 4.5 uses Sun's 1.1.8 JDK on Windows NT and Solaris, and Sun's 1.1.7 JDK on HP-UX. This is the only version officially supported by Apple. In addition, WebObjects 4.5 supports Sun's Swing interface library, version 1.1.1.

Question 2 : Does Apple support Just-in-Time (JIT) compilation with WebObjects 4.5?

Answer : JIT functionality is not available in this release of WebObjects. WebObjects applications spend much of their time running compiled framework code; the speed benefits of this approach are greater than would be seen with JIT-compiled Java code.
