JRuby 1.3 Fails to Execute Embedded Ruby code in Java
-----------------------------------------------------
Key: JRUBY-3633
URL: http://jira.codehaus.org/browse/JRUBY-3633
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.3RC1
Environment: Mac OS X 10.5.6, Intel Core Duo Macbook, Java 1.6
(SoyLatte -- http://landonf.bikemonkey.org/static/soylatte/)
Reporter: Saad Mahamood
When trying to evaluate Ruby code within Java, the following code fails to
execute and brings up a java.lang.NoSuchMethodError Exception:
ScriptEngineManager scriptEngineManger = new ScriptEngineManager();
ScriptEngine scriptEngine = scriptEngineManger.getEngineByName("jruby");
scriptEngine.eval("puts 1 + 2");
Results in JRuby 1.3:
Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError:
org.jruby.Ruby.runNormally(Lorg/jruby/ast/Node;Z)Lorg/jruby/runtime/builtin/IRubyObject;
at com.sun.script.jruby.JRubyScriptEngine.evalNode(JRubyScriptEngine.java:454)
at com.sun.script.jruby.JRubyScriptEngine.eval(JRubyScriptEngine.java:180)
at javax.script.AbstractScriptEngine.eval(AbstractScriptEngine.java:247)
at
uk.ac.abdn.babytalk2.readability.ReadabilityScore.generateReadabilityScores(ReadabilityScore.java:449)
This exception even after setting the correct JAR libraries on the classpath
(jruby-engine.jar, bsf.jar, and jruby.jar) and the correct VM parameter
(-Djruby.home="/usr/local/jruby-1.3").
Regressing back to JRuby 1.1.6 fixes the error and the ruby code is
successfully evaluated by the script engine.
