Hello,

My name is Valerio and I’m a developer of the CADIT company in Verona, Italy.

I am running tests with IKVM [ikvm-0.38.0.2] in order to compile libraries in FOP 0.20.5. NET and use them in applications .NET 2.0.

I'm experiencing some problems in the management of images that I cannot resolve.

When I try to generate a PDF from a FO that includes a picture I encounter this exception:

FOP ExampleFO2PDF

Preparing...

Input: XSL-FO (c:\work\prtTestIMG.fo)

Output: PDF (c:\work\prtTestIMG.pdf)

Transforming...

[INFO] Using com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser

roperties

ass java.lang.ClassCastException - Unable to cast object of type 'java.io.Buffer

edInputStream' to type 'java.awt.image.ImageProducer'.

[INFO] Parsing of document complete, stopping renderer

Can you give me some advice on how to resolve this issue?

Attached you’ll find the source FO and sample I used for this test.

Many thanks and Best Regards, Valerio

Hi,

FOP has duplicate resources in the jar files. That you need to compile it in multipe dll's. With ikvm 0.40 you can use:

ikvmc -target:library -sharedclassloader { avalon-framework-4.2.0.jar } { batik-all-1.7.jar } { commons-io-1.3.1.jar } { commons-logging-1.0.4.jar } { fop.jar } { serializer-2.7.0.jar } { servlet-2.2.jar } { xalan-2.7.0.jar } { xercesImpl-2.7.1.jar } { xml-apis-1.3.04.jar } { xml-apis-ext-1.3.04.jar } { xmlgraphics-commons-1.3.1.jar }
