Hello,
I attended a talk about [Hot]Java at Computer Literacy in McLean, VA
yesterday and after thinking about it overnight I have a few questions.
The fellow giving the talk (Harry Foxwell?) talked about a method of
"certifying" java byte codes retrieved over the net using RSA. I have
seen hints of this mechanism in the various documents on the Java web
server as well. Some questions come to mind:
- Is this mechanism in place?
- If so, where can I take a look, or if not, can you expand upon the
nature of this facility?
- What are the implictions of using RSA on the free distribution of Java?
The idea of a browser asking a server for code to implement a new content
type or protocol that the browser doesn't uderstand was mentioned in the
talk and is also discussed on your web page. The presenter at the talk
indicated there was a requirement of some server-side support for this
mechanism - is this really the case? Can you provide more information
about how this (second request to get code to implement new features)
mechanism works?
In working on my own applet, I find a need to present the user with a
listing of a directory (but the FileDialog doesn't do the trick).
Is there a directory object somewhere that I'm missing? If not, is one
planned or do I need to write a native method to handle this?
Finally, I see alot of talk about how Java produces portable code. This
is true provided there is a Java runtime available on the target system.
(This doesn't seem different from any other system that requires runtime
support.)
As a developer, I am wondering how long it will be before "Industrial
Strength" Java runtimes are available on the wide variety of platforms
I'd like to target (i.e. SunOS (4.x in addition to Solaris), Dec Unix,
AIX, HPUX, MacOS, SCO, MS*DO[W]S, OS/2) - when will the market for Java
apps reach critical mass?
I know Netscape claims that they will have Java support in Q4 - does anyone
know if thats calendar or fiscal year? Will this be across all supported
platforms?
I have read OSF's announcement. It seems they are only committed to an
assessment of the technology. Does anyone have any information about firm
plans from vendors like DEC, IBM, SGI, HP or SCO?
Thanks,
Noam
