Scripting language support

Follow up to the scripting languages JSR-223... I must emphasize my dissatisfaction with the web-only nature of the scripting language support initiative. One of the biggest issues I have with JSP is that it is intimately tied to the HTTP request and response. Velocity comes to the rescue (and I'm sure there are other alternatives - please add them to the comments below). Once upon a time the Velocity team even considered submitting it as a JSR.

To the JSR-223 team: please consider broadening the design to allow for scripting hooks in plain ol' J2SE - this will allow us to have a standard way to do things like the following:

• Send templated e-mails (something which we've used Velocity for)
• Generating static templated files, such as a static HTML view of my personal blog (again, I'm using Velocity currently).
• Custom code generators. Stuart Halloway has a code generation example using JSP in his wonderful book, and I suspect he did it this way to keep to pure out-of-the-box Java rather than introducing a third-party tool like Velocity. His example required he run the code generator in a web browser, and cut and paste the results to their final destination.
• I'd like to see more integration with scripting languages to control business rules, allowing run-time flexibility.
• And much more, I'm sure (leave your uses scripting within Java in the comments below)

Comments

• You said it!
  Indeed! In our latest project, we've used WebMacro (similar to Velocity) to format e-mails, generate Java and C++ code, and generate documentation in addition to web pages. Restricting JSR223 to web-tier scripting would be missing a big opportunity.

• Keeping My Fingers Crossed
  I sent email to the JSR expert group about this and asked them to support a scripting framework similar to the Bean Scripting Framework in J2SE. This would make it easier for the Zend group to plug in PHP support. Currently PERL, JavaScript, NetRexx, and Jython are supported. It would make it possible to script both client-side Swing code, and server code.
