I no longer get the AbstractMethodError when trying to extend FOP but...

2002-11-21 Thread Raffi Simon

WHen I downloaded the FOP I took both fop-0.20.4-src.tar.gz and fop-0.20.4rc-src.tar.gz which is the best to use as FOP. the one with the RC was the one giving me problems.

I have attached my ExtElementMapping file and I also rebuilt FOP with debugging turned on this is the error I get:

AbstractMethodError means that a method on a class is called that is
abstract. Compare your implementation with
org.apache.fop.svg.SVGElementMapping. addToBuilder is just plain public
and that's how it should be. Going to bed now...back in 9 hours.

as a test, I took the ExtensionElementMapping.java file that comes with the sourse files and I added a system.out.println to the code and compiled it and placed it in the classpath, I still get the same exception. I do not think this has to do with my implementation.

Turn on debug info in the build.xml and recompile FOP. Having line
numbers will make it a lot easier for you to track down the problem.
Looking at the source of Driver I guess you don't have a method
addToBuilder(FOTreeBuilder) in your ElementMapping implementation.

AbstractMethodError when trying to extend FOP

2002-11-21 Thread Raffi Simon

I follow the directions to extend FOP, I created a jar file with my classes and place a org.apache.fop.fo.ElementMapping file in the jar and when I run the FOP with my custom element I get the following.
[INFO] FOP 0.20.4rcException in thread "main" java.lang.AbstractMethodError    at org.apache.fop.apps.Driver.addElementMapping(Unknown Source)    at org.apache.fop.apps.Driver.addElementMapping(Unknown Source)    at org.apache.fop.apps.Driver.setupDefaultMappings(Unknown Source)    at org.apache.fop.apps.Driver.(Unknown Source)    at org.apache.fop.apps.CommandLineStarter.run(Unknown Source)    at org.apache.fop.apps.Fop.main(Unknown Source)
Can anyone help?
