ScriptFactory for JSR-223 [SPR-5215]

[spring-projects-issues]

Papick G. Taboada opened SPR-5215 and commented

Spring provides some dynamic language support:

http://static.springframework.org/spring/docs/2.5.x/reference/dynamic-language.html

The JSR 223 provides scripting for the Java platform:

http://www.jcp.org/en/jsr/detail?id=223

Wouldn't it be interesting to provide dynamic language support through that API,
so we could plug in our favorite dynamic language?

We've considered this for Spring 2.5 already but it turned out to be non-trivial, unfortunately. We'll revisit this for Spring 3.0.

Got a JSR-223 based StandardScriptFactory working with Groovy, JRuby and Nashorn on JDK 8 in the meantime, including a <lang:std> configuration element. To be committed soon.

Note that there are limitations for JSR-223 with Groovy and JRuby that still make our native support for those worthwhile. However, for JavaScript, the JSR-223 based approach is the only way to go.
