Bootstrap class loader - system property - sun.boot.class

[Karen Kinnear]

Vigneswaran,

In the hotspot source code, the bootstrap class loader is in
src/share/vm/classfile/classLoader.hpp,cpp.

It works very closely with the VM's common class loading logic
which is in
src/share/vm/classfile/systemDictionary.hpp,cpp

To better understand sun.boot.class.path processing in the vm,
look in src/share/vm/runtime/arguments. cpp

at the comments for SysClassPath:
// Constructs the system class path (aka boot class path) from the  
following
// components, in order:
//
//     prefix           // from -Xbootclasspath/p:...
//     endorsed         // the expansion of -Djava.endorsed.dirs=...
//     base             // from os::get_system_properties() or - 
Xbootclasspath=
//     suffix           // from -Xbootclasspath/a:...
//
// java.endorsed.dirs is a list of directories; any jar or zip files  
in the
// directories are added to the sysclasspath just before the base.

hope this helps,
Karen
