Im trying to create and pass a java array to a java method.
According to the CallingJavaFromJRuby, one could just use the to_java
method to create the java array. However, using to_java is not
creating a Java array but org.jruby.java.proxies.ArrayJavaProxy. If I
pass the proxy array to the java method that requires a java array,
the java method issues an exception:
NameError: no method 'addGlobalAttribute' for arguments
(org.jruby.RubyString, org.jruby.java.proxies.ArrayJavaProxy) on
Java::UcarNc2::NetcdfFileWriteable
Am I doing something wrong?
Thanks,

The error message is unfortunately misleading here (and I'd appreciate a bug report so we remember to fix it in 1.7 timeframe). You *are* actually creating a Java array, but for Ruby to handle it like a Ruby object we wrap it in another object of type ArrayJavaProxy. The error is probably caused by calling a method with the wrong type of argument. How are you creating the Java array via to_java? (show code, please) - Charlie

Hi Charles, Thanks for your reply. Ill file the bug report. You are right. Ive figured the problem out. The method Im calling is expecting an Array, but not a Java Array. It is the array type defined in the library Im using. Thanks for your help.
