Java is only available if you call Java.Initialize before to load the java runtime.
Supported data types include: void, int, long, boolean, string, double, float, char, byte, object, byte array (for container), char array (using FileMaker text).

For PDF content: If you have a DynaPDF Pro license and DynaPDF functions initialized, this function can add previews for the PDF file on Windows and Linux. For MacOS, we make them with PDFKit.
