similar to: RJB in Rails - setting JAVA_HOME correctly in environment.rb

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/.

Hello, I just started playing with RubyOnRails. It is indeed fascinating! I have a question about using rails models to connect to backend Java (i.e. EJBs) instead of database. Any pointers will be appreciated. Thanks and Regards, Khaled -- Posted via http://www.ruby-forum.com/.

Hi there, What are you using for text search engine in your rails applications ? I have been using simple search for simple applications, but then I need to search text in model instances inside collections such as user.documents and the like. I believe that simple search does not support any sort of ranged queries, and sql like might be overkill for tables with lots of records. Bests, Sergi

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

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

Heya all -- I recently downloaded the RJB 1.1.1 gem, and the install seemed to go fine.

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 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

While building i got this error Error: JAVA_HOME is not defined correctly. I wonder why vmkit requires JAVA_HOME, i would expect it to be independent of any java staff except the classspath. Am i missing something? Thank you Foivos

I''m trying to figure out how Ruby in general, and/or anything extra Rails may have, can talk to Java APIs of third party server apps. After quite a few search attempts net-wide and on ruby forums, and with "Programming Ruby" in hand, I''m coming up with zilch. Either I''m not finding it, or I''m not recognizing it. I''m assuming there has

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

I am using ferret right now, and it works great for all my regular text documents/information. My problem arises when I want to index/search all of our assets (mostly pdf files). Currently, there is no way to READ pdfs from Ruby. Because of this I have to resort to using Java to read the PDF''s and then Lucene to index them. My problem here is a couple things. One, to index a asset I have

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: I'm trying to find a search tool for a website I am planning. The many CMS packages I've tried fall short when it comes to configurable search modules. I'd appreciate comments/suggestions on the suitability of Xapian given the following: a) the web site under development will have upwards of 1500 URL links to other Internet locations. b) each URL will have --
