similar to: rjb failure: can't create Java VM

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 =

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

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

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 tried a couple of methods for getting this

Greetings. I am trying to list all keys in a java.util.HashMap field. The Java code to do this looks like: # Collection c = hMap.values(); # # //obtain an Iterator for Collection # Iterator itr = c.iterator(); # # //iterate through HashMap values iterator # while(itr.hasNext()) System.out.println(itr.next()); So, I took a stab at the ruby version: # I have a java hashmap called fields

Heya all -- I recently downloaded the RJB 1.1.1 gem, and the install seemed to go fine. However, when I try to require ''rjb'' I get the following error: no such file to load -- rjb Has anyone seen this before? Any thoughts what it could be? Thanks so much! -Lucas -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this

I am trying to do file i/o with rails and rjb and can''t figure out a way to make this work. Here''s what I am trying to do: - a user uploads an image to the server via a standard html form: <%= file_field("blog", "attach") %> - this returns a ruby File object to the controller in params[:blog][:attach] - then I need to convert this into a Java

Hi, I am unable to install the package rJava. I tried doing what the output suggests, but it doesn't help. How can I get R to find/recognize my Java installation?

Hi folks: I'm trying to update my JGR and related packages, but run into a compile problem, that I suspect must be affecting others. I get this output when compiling rJava, JavaGD, etc.: ## checking Java support in R... present: interpreter : '/usr/bin/java' cpp flags : '' java libs : '-L/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server

Hi Ista! Thanks a lot for your support!! It puzzles me because it?s the first time that something like this happens to me. I?m aware that root and user don?t have the same environmental variables here. However, I don?t know why root chooses Java 9 and my user chooses Java 10. Isn?t Java 10 ready to be used as a root? It seems that we are going to have to wait until rJava releases a new

Hi Jeff!! I really don?t know if running R CMD javareconf with sudo has posed a problem here, now or in the past. What I know is sometimes it?s the only way to really config it, if I don?t run with sudo, in the end it asks me if I want to overwrite the configuration from root override rw-r--r-- root/admin for /usr/local/Cellar/r/3.4.4/lib/R/etc/Makeconf?
