Hi, my composite has a ruby implementation. In my Ruby file I require
"rubygems" and some other ruby files. How do I set those folder and
files in my sca java project ? I tried with calculator script in
eclipse IDE. I works fine but if I add new a "require rubygems" in
the .rb file I get an error <unknown>:19: no such file to load --
rubygems (LoadError).
Any idea where and how do I configure Ruby dependencies in the java
sca project under eclipse?
thanks a lot Susanta
I am looking into this. To test what happens with "require" statements
I changed one of our scripting samples:
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/samples/calculator-script/src/main/resources/calculator/SubtractServiceImpl.rb
and added a "require" as follows:
require 'rexml/document'
include REXML
def subtract(n1, n2)
doc = Document.new <<-eof
<Hello xmlns="http://test";>
<name>Foo</name>
</Hello>
eof
print doc
return n1 - n2
end
and it works, I'm getting:
<Hello xmlns='http://test'>
<name>Foo</name>
</Hello>
3 - 2=1.0
REXML is part of the jruby distribution. Next, I'm going to try to
require another .rb file in the same project and will let u know what
I find.
I made a small change to our JRuby integration code to add the path to
the rubygems hiding inside jruby-complete-1.0.jar to the Jruby loadpath.
I also made a small change to improve the Exception reporting, you
should now see the JRuby exception messages.
The changes are available in SVN revision r580145 of the Tuscany trunk, see:
http://svn.apache.org/viewvc/incubator/tuscany/java/sca/modules/implementation-script/src/main/java/org/apache/tuscany/sca/implementation/script/engines/TuscanyJRubyScriptEngine.java?view=diff&r1=580144&r2=580145&pathrev=580145
This should allow you to "require 'rubygems'".
You may also have to configure your environment as described in the
JRuby Gotchas section there:
http://www.headius.com/jrubywiki/index.php/Java_Integration#Embedding_with_Bean_Scripting_Framework
Why gems are you using? Any Rails by any chance? I think it would be
really cool to show Rails working with SCA...
Hope this helps.
