HTML to PDF Need :NoSuchMEthod Erros on
callingorg.apache.fop.fo.FOTreeBuilder in Driver class
Can some one please throw light as why the Driver class is missing in version 1.0.0. I used version.2.03 but then it has "init" method missing for FOPTreeBuilder.
O just simply want to convert HTML into PDF. I believe there has to be a way within Apache Fop to do this ? Am I wrong?
Which version of FOP supports HTML to PDF conversion? IS there a way one can convert html into a .fo file or XML and then FOPFOtpPDF or FopXMLToPDF?
HOw does one proceed on just html page being the input for which PDf needs ot be created? IS there any provision for this html to PDf conversion?Is there a sample code in any of the versions of FOP which converts HTML page into a
PDF? Even if it is not in the example I can use a Java class if at all it is present in any of the FOP versions.
Is this something out of scope for FOP?>

Hello GuysBit new on Apache FOP. I am trying to run a demo code to convert HTML into PDF. I am getting following exception on using fop 0.20.5 versionI could not find the driver class in fop 1.0.0 version.IS there a sample code that converts html into pdf in FOP 1.0.0 version. I need urgently some sort of HTML to PDF conversion library. Am I missing here? Would FOP work for HTML to PDF conversion? Any help would be appreciated.

AW: HTML to PDF Need :NoSuchMEthod Erros on
callingorg.apache.fop.fo.FOTreeBuilder in Driver class
Posted by Georg Datterl <ge...@geneon.de>.
Hi Kapil Garg,
Between FOP 0.20 and Fop 1.0 there was a complete internal redesign. Examples how to start FOP now should be available, fop 0.20 is no longer supported.
A transformation from HTML to PDF will most likely never be perfect. There are transformation files out there and there are commercial products, but doing it on your own will only help you for simple pages. As soon as (for example) CSS was involved, I was completely lost.
Regards,
Georg Datterl
