What is SCA Component for Ruby with IBM WebSphere Process Server?
This prototype provides the capability of implementing an SCA (Service Component Architecture) component as a Ruby script and invoking it using the Bean Scripting Framework (BSF) functionality provided by JRuby. This SCA component uses the SCA extension capabilities to create a new implementation (similar to the BPEL implementation in WebSphere® Process Server).
With the popularity of Ruby, it is easy to imagine users developing their implementations in Ruby in order to exploit the advantages provided by the scripting language. This prototype provides a simple mechanism for developing a component implementation with simple Ruby scripts.
How does it work? The developer must create a Ruby component following the SCA programming model. The developer first writes a schema file to define a component; then the component file in this scenario takes the location of the Ruby script as a parameter. Next, the developer can create an implementation in Ruby script, which then implements a Java interface (the capability of implementing a Java interface is provided by JRuby, the Java interpreter for Ruby). After the component is ready, the developer can invoke it using the standard client API as defined by SCA.
