similar to: Running Java code in rails

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. So, I''m not very familiar with the java world. Can anyon tell me how/if java development can complement Ruby on Rails development? I''m not interested in how java can duplicate Rails

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

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

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

Has anyone attempted to run Rails inside of JRuby? Is that even possible? Aside from the performance implications, is it a bad idea? I''m thinking that it might be useful in very rare cases where a Ruby/Rails - equivalent of a Java solution may not exist yet. Any thoughts? Wes -- Posted via http://www.ruby-forum.com/.

hi, I need help to call java classes from the a controller action. I can call a java class from a ruby script, but when I am trying to call in controller, then require ''java'' itself gives me load error. I have java 1.4, jruby 0.9.0 and ruby 1.8.5 installed.

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

Hi, In my application, I have to make 3rd party java apis. Actually, I have to use a sms gateway provider''s apis. They have a java sdk which I have to use to send and receive sms. How can I call java apis from within a controller? In my controller, I have to receive request and use the java api to get the data out of request. Process the data in controller action and then send the

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/.

Is it possible to utilize java libraries from a RoR application? I saw some stuff about Web Services (i.e. SOAP), so obviously that is one way. I also was looking at the JRuby project... I was just curious how serious the efforts are to integration java and ruby and how that relates to the rails framework. Thanks for your thoughts! --~--~---------~--~----~------------~-------~--~----~ You

I have the need to take existing PDFs and populate them with data entered via HTML forms. Data saved to database, entered in to PDF file, PDF file with data archived, and then distributed va email and/ or download. The languuage I previous did all my web work in, Lasso, had this stuff built in, but it appears not to be so with Ruby or Rails. The latest info I can find on this is a year

hello, I am using Jruby on Rails. Does anyone know if you can expose a RoR object as a java class so that you can call it directly from java without having to go through a service layer like REST ?

Here are some notes from the scalability session of last week''s Rails camp. They were entered by another session participant and are posted at: http://www.rubyonrailscamp.com/10%3A15%2Bsession%2B-%2Bscaling The key points from my point of view: - the Ruby VM is sketchy, rather like the Java VM around 1997 - the single threaded nature of Rails dispatch handling means we may incur a

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 I''m doing some server-side graphics with Java2D and I''m trying to stream the resulting image to the browser using send_data. When I try to view the image that I streamed, the browser just shows the URL in the window as a very small image (about .4 kb) when I am using jpeg format. For png, it tells me that the image has errors and can''t load it. Here''s what

I''ve spent the last year developing a large Ruby on Rails 2.0 application with over a 100 tables and controllers and hope to be deploying it soon. Before I moved from my Windows XP computer to deployment, I wanted to run it in a local Linux environment to sort out: 1. Amazon S3 files 2. RMagick (went south when I upgraded to Rails 2.0) 3. ARMailer (mail spooling program) I''ve

Last week I posted a question about monitoring Rails applications. Basically, the java folks at my business cited one of their reasons for sticking with Java is it''s monitoring tools. After picking some ears, I found out that the one we''re looking at most is JBoss Operations Network. And I have to say, it''s pretty neat.
