ExceptionInInitializerError

[coospaa]

Dear all,

I'm using Fop-0.20.5 to generate pdf here. Inside Fop, it calls some methods defined in jai_core.jar and jai_codec.jar. At first, the application gave me NOClassDefFoundError. It was located at org.apache.fop.image.JAIImage.loadImage(JAIImage.java:97). So I added jai_core.jar and jai_codec.jar into the manifest file of Fop.jar. And then it gave me the error listed below:

java.lang.ExceptionInInitializerError: java.lang.IllegalArgumentException: Instance(101) of javax.media.jai.JAI$RenderingKey already registered

Could anyone gimme a hand? I'm totally baffled.

Thanks and best regards,

isn't fop open-source?
So you could get the source, and debug through it.

ExceptionInInitializerError is coming from the constructor, or a static Initializer-Block, invoked on the first call to the class, or from a static definition like:

static FooBar foobar = new FooBar ();

Perhaps a look at the docs for javax.media.jai.JAI$RenderingKey helps too.
