-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 OK. This is strange. I have the following stylesheet. The problem is that I can't use an extension without a root element (NPEs). <xsl:stylesheet xmlns="http://www.w3.org/1999/xhtml"; xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:tasks="http://schemas.openprivacy.org/reptile/settings/jvm/tasks"; xmlns:bootstrap="http://schemas.openprivacy.org/reptile/bootstrap"; xmlns:pe="xalan://org.openprivacy.reptile.extensions.JVMProperties" xmlns:jp="http://schemas.openprivacy.org/reptile/java/properties"; extension-element-prefixes="pe" version="1.0"> <xsl:output indent="yes" omit-xml-declaration="yes"/> <xsl:template match="/bootstrap:bootstrap"> <jp:properties> <!-- fill in properties --> <pe:properties/> </jp:properties> </xsl:template> </xsl:stylesheet> The only problem is that if I remove the <jp:properties> parent node I get an Exception. Example: <xsl:template match="/bootstrap:bootstrap"> <!-- fill in properties --> <pe:properties/> </xsl:template> I tried to find an entry about this in Bugzilla but didn't see anything that could apply. Here is the offending code from the stack trace I will include below: public void addAttribute( String uri, String localName, String rawName, String type, String value) throws TransformerException { QueuedStartElement qe = getQueuedElem(); if ( !qe.nsDeclsHaveBeenAdded() ) addNSDeclsToAttrs(); - ----------- and the stack trace ------------------- file:/usr/local/rsync/projects/reptile/tmp/../src/xsl/settings/jvm/properties.xsl; Line 48; Column -1; javax.xml.transform.TransformerException: Unknown error when calling extension! at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.java:1269) at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:3070) at java.lang.Thread.run(Thread.java:498) - --------- ; SystemID: file:/usr/local/rsync/projects/reptile/tmp/../src/xsl/settings/jvm/properties.xsl; Line#: 48; Column#: -1 ; SystemID: file:/usr/local/rsync/projects/reptile/tmp/../src/xsl/settings/jvm/properties.xsl; Line#: 48; Column#: -1 javax.xml.transform.TransformerException: Unknown error when calling extension! at org.apache.xalan.templates.ElemExtensionCall.execute(ElemExtensionCall.java:326) at org.apache.xalan.templates.ElemForEach.transformSelectedNodes(ElemForEach.java:499) at org.apache.xalan.templates.ElemApplyTemplates.execute(ElemApplyTemplates.java:193) at org.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2251) at org.apache.xalan.transformer.TransformerImpl.applyTemplateToNode(TransformerImpl.java:2134) at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.java:1246) at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:3070) at java.lang.Thread.run(Thread.java:498) - --------- java.lang.NullPointerException at org.apache.xalan.transformer.ResultTreeHandler.addAttribute(ResultTreeHandler.java:1183) at org.apache.xalan.transformer.ResultTreeHandler.addAttribute(ResultTreeHandler.java:1291) at org.apache.xalan.transformer.ResultTreeHandler.addAttributes(ResultTreeHandler.java:1313) at org.apache.xalan.transformer.ClonerToResultTree.cloneToResultTree(ClonerToResultTree.java:208) at org.apache.xalan.transformer.ResultTreeHandler.cloneToResultTree(ResultTreeHandler.java:819) at org.apache.xalan.extensions.XSLProcessorContext.outputToResultTree(XSLProcessorContext.java:260) at org.apache.xalan.extensions.ExtensionHandlerJavaClass.processElement(ExtensionHandlerJavaClass.java:428) at org.apache.xalan.templates.ElemExtensionCall.execute(ElemExtensionCall.java:305) at org.apache.xalan.templates.ElemForEach.transformSelectedNodes(ElemForEach.java:499) at org.apache.xalan.templates.ElemApplyTemplates.execute(ElemApplyTemplates.java:193) at org.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2251) at org.apache.xalan.transformer.TransformerImpl.applyTemplateToNode(TransformerImpl.java:2134) at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.java:1246) at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:3070) at java.lang.Thread.run(Thread.java:498) - --------- java.lang.NullPointerException at org.apache.xalan.transformer.ResultTreeHandler.addAttribute(ResultTreeHandler.java:1183) at org.apache.xalan.transformer.ResultTreeHandler.addAttribute(ResultTreeHandler.java:1291) at org.apache.xalan.transformer.ResultTreeHandler.addAttributes(ResultTreeHandler.java:1313) at org.apache.xalan.transformer.ClonerToResultTree.cloneToResultTree(ClonerToResultTree.java:208) at org.apache.xalan.transformer.ResultTreeHandler.cloneToResultTree(ResultTreeHandler.java:819) at org.apache.xalan.extensions.XSLProcessorContext.outputToResultTree(XSLProcessorContext.java:260) at org.apache.xalan.extensions.ExtensionHandlerJavaClass.processElement(ExtensionHandlerJavaClass.java:428) at org.apache.xalan.templates.ElemExtensionCall.execute(ElemExtensionCall.java:305) at org.apache.xalan.templates.ElemForEach.transformSelectedNodes(ElemForEach.java:499) at org.apache.xalan.templates.ElemApplyTemplates.execute(ElemApplyTemplates.java:193) at org.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2251) at org.apache.xalan.transformer.TransformerImpl.applyTemplateToNode(TransformerImpl.java:2134) at org.apache.xalan.transformer.TransformerImpl.transformNode(TransformerImpl.java:1246) at org.apache.xalan.transformer.TransformerImpl.run(TransformerImpl.java:3070) at java.lang.Thread.run(Thread.java:498) - -- Kevin A.
