LOL, nice exchange - where have you expected print to happen? - On 
my printer :-)

CGI is possible indeed. I did a small tutorial a while ago: http://arnoldvanhofwegen.com/blog/simple-red-cgi-scripting-possible/

Do you want to add using it with GET and POST ?
Arnold

Very much so and connecting it to my MySQL database as well! But 
that is not yet possible at this time. I do not see a use for a form 
if I cannot save information from it.

R2 has all these possibilities, on rebol.org are various examples 
of scripts. For Red we might train our patience muscle of finance 
Nenad in the 'right' direction.

We can finance Doc anyway, but - he knows his priorities, and imo 
CGI is not one of them right now :-) Well, Red still needs some other 
basic stuff, namely objects, I/O (files, networking), parse ... we 
are getting there, it will just take some time ....

Kaj says CGI is possible using get-env to retrieve the request data

CGI support is trivial, you don't need me to add it to Red.
First release of prototype low-level bridge with Java world:

https://github.com/dockimbel/Red/tree/dyn-lib-emitter/red-system/bridges/java
This is a low-level interface suitable for Red/System. Red will have 
a higher-level abstraction layer for interacting with Java.
This has been tested on Windows only currently, let me know if there's 
issues on other platforms.

Can't somehow build it ....
do/args %rsc.r "%bridge/java/JNIdemo.reds -o %bridge/java/JNIdemo" 
... there's a typo, should be %bridges/

You need to have the JDK installed.
Ah thanks!
Fixed.

Don't want to have JDS installed :-)
I got exe, it just prints nothing ... wouldn't I be fine with jus 
same JAVA libs?
DocKimbel

Exe??

Sorry, forgot to add the -dlib option in the README.

ok ...

JNIdemo.dll
DocKimbel

[7649x2]
Right.
Now you need to compile the Java side.
Pekr
9-May-2013
[7651]
you mean JNIdemo.java, right? And for that, I need JDK installed 
....
Andreas

Someone can also send you the compiled .class file, but you'll at 
least need the JRE installed :)
DocKimbel
9-May-2013
[7653x2]
Yep.
Right, if you need to install Java, go for the JDK instead of the 
JRE.
Pekr
9-May-2013
[7655x2]
My idea is, that I don't need JAVA at all, and that Red compiler 
spits out final app for me :-)
well, I mean - that I don't need JDK, just typical JAVA client installation 
...

Andreas, does it work on Linux for you? It seems there's a library 
path access issue there.
Andreas
9-May-2013
[7658x2]
That's the JRE.
(@Pekr ^^)
Pekr

JRE is typically installed on Windows machines, but not sure nowadays. 
But I somehow has it insatlled on my notebook ...

@Pekr: http://bolka.at/2013/red/JNIdemo.class(compiled with Java 
7; hope that doesn't cause problems).

Pekr: if you want to put yourself in the end-user shoes only, then 
just forget about this Java stuff until we get full Android support. 
If you want to test the steps in the meantime, just install the JDK.
Andreas, you need to publish the events.class file too, or they won't 
be able to close the window. ;-)
Pekr
9-May-2013
[7664x2]
downloading JDK, but good to know, that end users will not need to 
fight all that stuff ...
well, what is the .class file good for anyway, even if I have JRE?
Andreas
9-May-2013
[7666]
The .class file is Java's "exe".
DocKimbel
9-May-2013
[7667]
Java 7: I think I've relied on Java 6 docs, but it should work as 
these are old APIs.

Hmm, on second thought, Pekr, if you don't know what .class are, 
maybe don't bother with JDK then...;-)
Andreas

With the JRE, you can run code in .class files.
DocKimbel
9-May-2013
[7671]
We'll provide precompiled classes for you to test.
Andreas
9-May-2013
[7672]
Hmm, the above classes don't run for me with a Java 6 JRE. So ignore 
them, if you don't have Java 7 already.

Well, looking into binary .class, I expected it being some kind of 
executable or package, just pressing Enter does nothing :-) So it 
is not mapped to JRE on my machine .... I selected it manually, and 
it says:

Could not find or load main class, or something like that ...
Andreas

open a command prompt, change to the directory the .class is stored 
in, and run `java JNIdemo`
