Difference between BasicProxyPreparer and VerifyingProxyPreparer?

[Esmond Pitt]

Subject says it all really. I've read the Javadoc and even the source code
and I can see that they are doing slightly different things, but what? and
for what purpose? when would I use one rather than the other?

TIA

There was some discussion in this thread:

http://archives.java.sun.com/cgi-bin/wa?A2=ind0702&L=JINI-USERS&P=7651
http://archives.java.sun.com/cgi-bin/wa?A2=ind0702&L=JINI-USERS&P=8722
...

The primary motivation was to facilitate specifying, in a
configuration file, arbitrary context elements, like a
BasicUntrustedObjectSecurityContext, to use for the
Security.verifyObjectTrust invocation (whereas BasicProxyPreparer
always uses the specified constraints as the sole context element).

Thanks Peter

context elements

Is there a proper definition of that somewhere other than 'determined by its
type'?

The classes that implement TrustVerifier specify how they use those
context elements, if at all. If I recall correctly, of the trust
verifier classes in the starter kit, only ProxyTrustVerifier uses
them: both for the constraints for the ProxyTrust.getProxyVerifier
remote invocation on the bootstrap proxy (must be specified), and the
UntrustedObjectSecurityContext for invoking methods on not-yet-trusted
classes (optional, defaults to a very restrictive security context).
