How can I write a File Path inside RegisterGroovy?

[Iian Valtierra]

Hello. 

I have the next line:

List<String> line= pdfread.convertToLine(pdfread.readContentPDF( path )); 

But, I had working with different path (absolute, relative, changing location) but ir doesn't work. 

I set the path of the parameter from FileMaker Script.

I'm looking for documentation but I can't find some interesting yet.

you will have to give some more context than this...

which library for instance and some code round it.
