Hi,
I am having some trouble getting systemjs loading on the Java 8 Nashron engine.
Here is my setup:

  • Java 8: 1.8.0_31
  • Spring boot: 1.3.0.RELEASE
  • SystemJS: 0.19.22

Here are the steps to reproduce this issue:

  1. Load system.js in Nashorn:
@Bean
public ScriptTemplateConfigurer universalConfigurer() {
    ScriptTemplateConfigurer configurer = new ScriptTemplateConfigurer();
    configurer.setEngineName("nashorn");
    configurer.setScripts(
          "static/node_modules/systemjs/dist/system.js"
           // ...
    );
    configurer.setRenderFunction("render");
    configurer.setSharedEngine(false);
    return configurer;
}
  1. Build and run. Nashorn should complain about No environment baseURI (Sorry for this long trace):

Nashorn is not currently supported as an environment.

The main environment hooks that need to be set up to get SystemJS to work are:

  • The ability to load a script dynamically
  • Getting the baseURI
  • Fetching a file
  • Eval

I'm more than happy to support Nashorn by wiring those in, and PRs are welcome, but it is not currently a development priority.

thank you @guybedford
Do you have any clue on how you would implement those hooks in Java world ? I obviously need to do more investigations about Nashorn first :)

This would need to be integrated in the module loader itself, eg by altering the fetch implementation at https://github.com/ModuleLoader/es6-module-loader/blob/master/src/system-fetch.js to have a scenario for Nashhorn. This is not currently implemented in SystemJS, but we can consider it or a possible Nashorn build.

@guybedford In Nashorn, you can call Java classes form JavaScript. So we can imagine having a Java implementation of the JavaScript fetch API which we will then use in SystemJS.
I will look at this more closely when I get more familiar with Nashorn ^^

Closing, to rather track any work here on the ES6 Module Loader project repo.
