TypeError when eval the source about load from classpath

[changkejun]

I copied the junit source and did the following test and got a typeError. How can I solve this?
the building and running jdk is 21.

        try (Context context = Context.newBuilder("js")
        		.allowExperimentalOptions(true)
        		.allowIO(IOAccess.ALL)
        		.option(JSContextOptions.LOAD_FROM_CLASSPATH_NAME, "true")
        		.option(JSContextOptions.NASHORN_COMPATIBILITY_MODE_NAME, "true").build()) {
    		Source src=Source.newBuilder("js", "load('classpath:efw/script/classpath_test.js');", "load-from-classpath.js").build();
            Value result = context.eval(src);
        }catch(Exception e) {
        	e.printStackTrace();
        }

The orginal source is here.

Here is my jar files about graaljs.

The js path.

load('classpath:<someResource>') works when the resource is on the classpath (i.e. when it can be loaded by a system classloader) : graal-js uses ClassLoader.getSystemResourceAsStream(<someResource>) under the hood. You seem to use Tomcat (i.e. a web server) where web application classes are typically not available on the classpath but are loaded using a special class loader. So, I don't think that you can use loading from the classpath in your case.

Thank you for your explanation. I close the issue and look into getSystemResourceAsStream.
