Hi, For those who might not be aware, rjb is a killer gem for using java classes inside your rails app (or any ruby code). Check it out at: http://rubyforge.org/projects/rjb/ I was able to successfully use it in one of my apps that required some code that is only available in java. And it''s much nicer than having to compile a java app, then shell out using backticks, get back the return

Hello, I''m having some problems when try to install rjb i get this message C:\Users\PC1090\Documents\RJB\rjb-1.3.8>ruby setup.rb config ---> bin <--- bin ---> lib <--- lib ---> ext C:/Ruby187/Ruby1.8.7/bin/ruby "C:/Users/PC1090/Documents/RJB/rjb-1.3.8/ext/extconf.rb" checking for jni.h... no *** C:/Users/PC1090/Documents/RJB/rjb-1.3.8/ext/extconf.rb failed

I am trying to do file i/o with rails and rjb and can''t figure out a way to make this work.

I''m trying to interact with a java library (Aspose Slides) inside of my Rails 3 app. I''m trying to get the rjb gem installed but I keep running into the same error when I try to start the app: [BUG] cross-thread violation on rb_gc() (null) Abort trap I''m on OSX 10.6.6, running ruby 1.8.7-p174 (via RVM) and Rails 3.0.4.

I MAY be able to derive something out of the present example given here : http://blog.codeinmotion.com/index.php/2006/12/22/pdf-generation-in-ruby-on-rails/ but this deals with filling out forms. Is there a simpler example that just allows you to talk to itext , send it some plain text and get back a pdf and then send that pdf to the user as downloadable / renderable data? -- Posted via

All, I am attempting to use RJB (Java-Ruby Bridge - see: http://arton.no-ip.info/collabo/backyard/?RubyJavaBridge) in my Rails app. The documentation says: "Both LD_LIBRARY_PATH and JAVA_HOME setting required in environment.rb file of RoR." However, it doesn''t say _how_ to set these variables in environment.rb. I''ve tried JAVA_HOME =

Help! On my Mac dev machine, everything works, and obviously on my Debian production server something is wrong. I set JAVA_HOME and LD_LIBRARY_PATH in environment.rb, but it''s still blocked. Anyone has experience with rjb? -- Posted via http://www.ruby-forum.com/.

Folks, I'm a bit puzzled by the fact that if I generate 100,000 standard normal variates using rnorm() and perform the Jarque-Bera on the resulting vector, I get p-values that vary drastically from run to run. Is this expected? Surely the p-val should be close to 1 for each test? Are 100,000 variates sufficient for this test? Or is it that rnorm() is not a robust random number generator?

Hello everyone, I am passing a variable (showco) to a partial using: <%= render(:partial => "form", :object => f, :locals=>{:mode => "edit", :showco => @showco } ) %> It works fine if there are no validation errors. However, when an error occurs and the form is redisplayed, the variable is not set. The @showco variable is initialized in the

In production I''ve setup a mongrel cluster of 2 servers. Now I''m using RJB(ruby java bridge). So I need certain java environment variables set before mongrel starts. So I set them: export LD_LIBRARY_PATH=/usr/java/jdk1.6.0/jre/lib/i386/:/usr/java/jdk1.6.0/jre/lib/i386/client/:./ export JAVA_HOME=/usr/java/jdk1.6.0/ Then I run "mongrel_rails cluster::start". Now

Hi all, I''m asking this question from the standpoint of a developer with almost 10 years experience with Microsoft technologies, mostly doing server side component and database work.

Without clarifying handle's lifetime, it is unable to see how long the callbacks which the handle owns will live. Then, Rust compiler will infer that the callbacks have 'static lifetime.
