Are the J2SE reflection and collection classes supported in J2ME?

The J2ME Connected Limited Device Configuration (CLDC) 1.0 spec does not require implementation of reflection or collection classes from J2SE. You can access the spec from the CLDC homepage, at:
java.sun.com/products/cldc

The J2ME Connected Device Configuration (CDC) and related Personal and Foundation Profiles may provide some support. Their specifications are not yet available for review. In the meantime, however, you can review the reflection support and limited collection class support provided by their predecessor technology, PersonalJava 1.2, via the specficiation link on the PersonalJava homepage, at:
java.sun.com/products/personaljava

PersonalJava 1.2 provides for some reflection support. Certain collection classes are also required if a manufacturer implements the optional code signing mechanism. For more information, please download the PersonalJava 1.2 specification and refer to sections 5.10 java.lang.reflect and 5.25 java.util, respectively.
