[x3d-public] Problem with conversions to Java, compiling and running generated Java, www.web3d.org/x3d/stylesheets/java/examples

[John Carlson]

Note the extra CDATA section in the generated Java and in the X3D (generated from second Java) below compared to the original above.  I need the later code in order to generate JSON in a test.  We will progress from here to the proper encoding of an MFString in Java.  X3D attached.  Let me know if we need the CDATA strings or if we are taking them out.

HelloWorldProgram.java

                colorTypeConversionScript.setSourceCode("ecmascript:" + "\n"
                                + "\n"
                                + "function " + inputColorFieldName + " (eventValue)" + " // Example source code" + "\n"
                                + "{" + "\n"
                                + "   " + outputColorsFieldName + " = new MFColor(eventValue); // assigning value sends output event" + "\n"
                                + "// Browser.print('" + inputColorFieldName + "=' + eventValue + ', " + outputColorsFieldName + "=' + " + outputColorsFieldName + " + '\\n');\n"
                                + "}");
