如何在JRuby Rails应用程序中调试Java代码

Question

On my rails part I use some Java-code packed into jars, I extract the class in ruby as follows: beanA = self.bean_factory().getBean("BeanA") , where bean_factory connects to the database and set up the spring context. The problem is when I'm running the application in debug mode I can't go inside that java object: beanA.method1() while the method invocation itself works OK.

You will not be able to debug the Java libraries unless your IDE understands Java and the libraries in question were compiled with debug information enabled. You'd also need to be using an IDE that understood both Ruby and Java, and the only one I can think of that would do this would be IntelliJ with the RubyMine plugin, unless Eclipse now supports Ruby as well.
