[REBOL] REBOL and Java integration Re:
From: rebol::techscribe::com at: 31-Aug-2000 16:42
Hi Jamie,
an option would be to use Java's socket (under MS Windows Winsock)
functions and connect to a function server written in REBOL (which could be
as small as four or five lines of code).
Send a character sequence consisting of the REBOL functions you want to
invoke including filenames or urls you want them invoked on, and then have
REBOL do the resulting string.
I.e. if
1. Java sends REBOL the character sequence
parse-webpage/get-title read http://www.rebol.com/
2. the function parse-webpage is defined in REBOL as
>> source parse-webpage
parse-webpage: func [string /get-title][
if get-title [
parse string [
thru <title> copy title to </title>
(page-title: title)]
]
]
return title
]
3. the REBOL server uses do to evaluate this incoming string
>> result: do submitted-script
4. and returns the result using a REBOL port,
5. then your Java app will get a
character sequence consisting of
{REBOL Technologies: Internet Platform for Business Relationship Management}
REBOL becomes kind of a background script evaluator.
Hope this helps.
