Create PDF with Coldfusion (openBD CFML engine) java

Wrestling to create PDF in Coldfusion using the following block with no success:

<cfset FileInputStream = CreateObject("java", "java.io.FileInputStream") >
<cfset File = CreateObject("java", "java.io.File")>

<cfset lic = CreateObject("java", "com.aspose.pdf.License")>
<cfset lic.setLicense(FileInputStream.init(File.init("E:\Tomcat\webapps\openbd\Aspose.Pdf.lic")))>


<cfset Document = CreateObject("java", "com.aspose.pdf.Document").init() >
<cfset demo_pdf = Document.init() >

<cfset Section = CreateObject("java", "aspose.pdf.Section").init() >
<cfset Text = CreateObject("java", "aspose.pdf.Text").init() >

<cfset sec1 = section.demo_pdf.getSections().add() >
<cfset sec1.getParagraphs().add(Text.init("Τέσσερα"))>
<cfset demo_pdf.save("E:\Tomcat\webapps\openbd\HelloWorld.pdf")>

The error produced is: "java.lang.NoSuchFieldException" on line "<cfset sec1 = section.demo_pdf.getSections().add() >".
