Niklas Heidloff recorded a short video. Thanks!
Watch the mini video to see the exporter in action.
Export your content of a database, like views or documents to HTML, XLS (Excel), RTF (Word & Co.) and PDF.
Additionally you may create templates for RTF and PDF files with placeholders and fill them. E.g. you could create serial letters with this function. Take a look at the fillRTFTemplatetoStream function et cetera
You find a javadoc inside the demo application. The java classes work in your SSJS on an XPage.
