Thanks Matt, Terence, This leads me to suspect the problem is with OSGI, I'm currently repackaging the FOP jars as an OSGI bundle (it's not on springsource unfortunately). I will update this thread if that resolves it.

Mind you, we're also using fop-pdf-images. I'd review what jars are actually being loaded - this sounds like a mismatch somewhere. Ah, java. Run once, run... once.

The images were JPEG and OSGI was not used. -Terence Bandoian On 11/24/2014 9:53 AM, Iain Soedring wrote: Hi, I have an xsl file that includes an external image: <fo:external-graphic src="/images/BrandGraphic.PNG"/> When running as a standalone Java application the transformer.transform function works, and I get a valid PDF file. When running in Tomcat/OSGI, on the same server (same JRE), I get the following error: FATAL ERROR: 'java.lang.IllegalArgumentException: Unknown function: gatherContextInfo' :Unknown function: gatherContextInfo If I remove the image from the XSL, everything works. I checked in the fop 1.0 source, and see that this comes from org.apache.fop.util.text.AdvancedMessageFormat public FunctionPart(String functionName) { this.function = getFunction(functionName); if (this.function == null) { throw new IllegalArgumentException("Unknown function: " + functionName); } } Unfortunately no stack trace is output when catching this exception, and tracing back through the code I can see various places from where this could have got called. the 'gatherContextInfo' function itself is in org.apache.fop.fo.FONode.java, and is overridden in sub-classes. On the class-loading side, I've verified that the same jars are loaded in both tomcat and standalone. The following are the ones that I find are essential for my transform to work: avalon, batik, commons-io, commons-logging, xmlgraphics. On tomcat there are many more libraries loaded, but the only overlap I can see is commons-logging, where my war file already uses a different version of this. I have asked the same question on stackoverflow: https://stackoverflow.com/questions/27066409/apachefop-tomcat-osgi-error-java-lang-illegalargumentexception-unknown-functio , but I haven't get much response beyond what I'd already looked at so far. One other issue I found running FOP in Tomcat/OSGI, was the need to override the PDF renderer, with this code: FOUserAgent useragent = fopFactory.newFOUserAgent(); PDFRenderer pdfrenderer = new PDFRenderer(); pdfrenderer.setUserAgent(useragent); useragent.setRendererOverride(pdfrenderer); fopFactory.addElementMapping(new FOElementMapping()); ... Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, useragent, out); otherwise the code would fail with: Caused by: java.lang.UnsupportedOperationException: Don't know how to handle "application/pdf" as an output format. Neither an FOEventHandler, nor a Renderer could be found for this output format. at org.apache.fop.render.RendererFactory.createFOEventHandler(RendererFactory.java:360) Does anyone have any idea what could be going wrong here?
