With JDK1.1, security manager should be the constraining factor to invoke
external programs through servlets. But with JDK1.2 it should be possible.
Security is more configurable in JDK 1.2 . As we all know browser's sandbox
is composed of Class loader + Security manager + byte code verifier. Is
servlet sandbox security model also similar. I think only Class loader part
is implemented differently, and rest is same.
Somebody can add more to this topic.
