Description
Hello,
I was trying to understand how FOP is working and I downloaded the latest stable version and created a new project in JDeveloper 10g. I'm using the binary release 1.0 . I could do run succesfully the examples using the command line. But when I'm trying to call it from any application, I always stumble on the same error which is the following (It's almost the same with all the example I tried) :
XML-22900: (Fatal Error) An internal error condition occurred.
javax.xml.transform.TransformerException: XML-22900: (Fatal Error) An internal error condition occurred.

Debugger disconnected from local process.
Process exited.
After analysing the error, I found that the attribute "delegate" is always null after running : transformer.transform(src, res);
Since those are your examples, they should work and have no errors. Just for fun I did edited the FOTreeBuilder class in the FOP.jar, adding if (delegate == null)
{this.startDocument()}So it began to work without errors, thought it's not correct since the PDF file is unreadable. I've tried the following examples :
ExampleFO2.java
ExampleXML2PDF.java
and the example in the user guide.
The only difference between your files and mine is that I created my own package in JDev, but I did copy/paste all the rest of your code.
I'll continue to search a way to correct the error.
