As I just now when Joachim Schuler (the computer science student) have read, there will be in NetBeans 6.0 provides comprehensive support for Ruby.
I do not know why Sun is so dedicated to Ruby. With Groovy has a Java-based scripting language that allows all Java classes (J2EE and personal) use. With its own compiler from the scripts can even use your own Java classes are created, so that the execution speed is increased by several times.
Based on there with Groovy Grails own web framework, the additional Spring (MVC) and Hibernate (OR mapping for databases) uses without the developer having to confront their extensive configuration. To run Rapid Application Development (RAD), I no longer need. Oh yes, all the Grails Web applications run on any Java servlet container (whether standalone or embedded in an application server), because they are J2EE compliant.
But back to Ruby. Anyone who has spent times 1 hour trying to find spaces where a tab belongs, will have Ruby cursed at this time. Certainly, the concepts of Ruby on Rails groundbreaking and pioneering, and thus can certainly explain the euphoria. That it will not suffice to establish Ruby in the business environment.
A good IDE is certainly an advantage. The integration into the existing business environment, it does not solve it. Because development is one thing. The application to operate later and another thing in the operation of the company has reluctantly every six months a new environment, the applications to run on.
I think Sun plans a large community with a tool to give to the NetBeans source and thus better position to Eclipse.
How beautiful the world would be if Oracle, IBM and Sun could agree on Eclipse and try to differ by only would support the IDE from each other. Space would be for everyone
