Subject Re: any HTML to PDF example within apache FOP?
Date Mon, 23 May 2011 07:50:16 GMT
Admittedly I am not familiar with HTML to PDF (and fairly new to FOP) but just wondering if
the java heap size is a factor at all with the memory issues? Can you please give more detail
about your setup? What environment? Do you have a -Xmx<size> option anywhere? If so
then is it possible to increase the heap size (unless I am on the wrong track of course).

Thanks.

-Mike

Subject: HTML to PDF :NoSuchMEthod Erros on callingorg.apache.fop.fo.FOTreeBuilder in Driver
class
Date: Sun, 22 May 2011 05:05:31 +1000


Hello Guys
Bit 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 version
I 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.


Exception in thread "main" java.lang.NoSuchMethodError: org.apache.fop.fo.FOTreeBuilder: method
