Example 1 with FormattingResults

use of org.apache.fop.apps.FormattingResults in project OpenClinica by OpenClinica.

the class PdfProcessingFunction method run.

/*
     * The run() method.  Note that we will assume that all variables (i.e. file
     * paths) are set here.
     * 
     * Running this will open a file stream, perform a transform with the *.fo 
     * file (note, does not necessarily have to have a *.fo suffix) and then 
     * return a success/fail message.
     * (non-Javadoc)
