Fetching Warning Messages
Hi,
I am facing one problem of fetching R warning messages in Java Code
using Rserve. It is easier to trap R Error messages by using catching
RSrvException. I came to know one way of fetching R Warning messages, i.e.
using "withCallingHandlers", below is my Java Program, which uses
withCallingHandlers of R :

JBuilder Reload buffers? confusion (any update?)
Hi,
We've got some Java projects that are being developed on both Unix and
NT and we're struggling with JBuilder 2.0 and its "File has been
externally updated, reload buffers?" messages. Has anyone found a fix?
Is it a bug in JBuilder? i.e should I save my hair and not spend any
more time investigating/trying to fix this problem?

passing graph image data from remote Rserve
Hello,
I am using Rserve to create a dedicated computational back-engine. I
generate and pass an array of data to a java application on a separate
server. I was wondering if the same is possible for an image. I believe
that Rserve supports passing certain R objects and JRclient can cast
these objects into their Java counterparts. If I generate a barplot in R
(remotely), can I pass the graph

Rails' scaffold controller generator - should it test json format also?
(Forgive me if this is incorrect, because I recognized this initially as
something in Rails 4.0.0.beta1 and have just done a cursory look over the
latest generator code.)
Noticed in Rails 4 that the test generated for a scaffold controller only
tests the html format instead of both html and json:

Still the big Icecast problem!
Easy... when I made this java applet :

I can provide my wall JBuilder project for those interested to use it.
Easy way:

windows program over a samba share
Hi,
I don't know if this is possible, but I'd like to install a window program (in
the specific JBuilder Personal) over a samba share, and then to mount a
network share as a disk from windows clients, so they can use the program. Is
it possible? Any idea on how to share windows programs from a linux server?
Thanks,

Versioning of Views; Our Approach
My friend Ben Willis and I have developed a gem for the versioning of Rails
views.
https://github.com/bwillis/versioncake
The versioning is done by the naming convention. Image the following
series of files :
show.v3.json.jbuilder
show.v2.json.jbuilder
show.v1.json.jbuilder
create.v2.json.jbuilder
create.v1.json.jbuilder
The developer pre-defines all view versions in their config. When a

Handshake exception in Rserve [Broadcast]
We had something similar, and as far as I recall the problem turned out to
be that we had not set the config file to allow remote connections.
This would probably be better put on the Rosuda mailing list:

Hope this helps,
