Could you post a simple working example to the wiki?

So this works:
byteArray = Rjb::import('java.io.ByteArrayOutputStream')
printStream = Rjb::import('java.io.PrintStream')
out = byteArray.new()
Rjb::import('java.lang.System').out = printStream.new(out)
err = byteArray.new()
Rjb::import('java.lang.System').err = printStream.new(err)
... [do something]
err.toString.should match(/WARNING/)
Thanks Alex!

Maybe worth considering just substituting System.out, System.err
with a
PrintStream hooked to a ByteArrayOutputStream, collecting the
result and
applying regexps to colorize and output to $stdout, $stderr
respectively.
That way, there's no messing with the classpath and no additional
interface
complexity.

So, I would have a .class file for the Java code needed, that I
would add
to buildr.The .class would be added to the RJB classpath, and the
manipulation itself would be done on Java.load.
I can probably to do this in a pluggable way (read: as a separate
project).

It should work fine and I don't see a better approach.

Hi everyone,
I'm trying to find a nice way to redirect the RJB output. I have
some
output
made directly from Java that I would like to reformat and
eventually
colorize.
From what I read, the best solution would be to replace the
PrintStreams
used in System.out and System.err by something that would pipe to
$stdout
and $stderr respectively.
From the RJB doc, I see RJB can bind a Ruby object to a Java
interface.
That
sounds like the right deal...
but PrintStream is a class.
The workaround is to have some Java code exposing an interface,
with a
PrintStream implementation that delegates everything to said
interface,
and
have RJB instanciate the interface and pass output along to
stdout and
stderr.
Was this attempted before ? Any advice on this ?
Thanks,
Antoine
