http://issues.apache.org/bugzilla/show_bug.cgi?id=35644 Summary: NullPointerException from SQLTransformer Product: Cocoon 2 Version: 2.1.7 Platform: PC OS/Version: Windows NT Status: NEW Severity: normal Priority: P2 Component: blocks AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I have a pipeline which consists of a file generator, the SQL transformer, and an XML serializer. Unfortunately, I forgot to add the database driver to the load-classes init param, so the DriverManager was unable to find anything to handle my serverURL and hence the SQL transformer was unable to get a connection. I expected to get an error, however, I didn't expect it to be a NullPointerException (stack trace below). Looks like the transformer needs to be more careful about what it passes into Xalan? At least in the Xalan 2.6.0 sources, ensurePrefixIsDeclared method has a check for null namespaces, but not for a null rawName...? java.lang.NullPointerException at org.apache.xml.serializer.ToStream.ensurePrefixIsDeclared(ToStream.java:2634) at org.apache.xml.serializer.ToStream.startElement(ToStream.java:1736) at org.apache.xalan.transformer.TransformerIdentityImpl.startElement(TransformerIdentityImpl.java:1020) at org.apache.cocoon.xml.AbstractXMLPipe.startElement(AbstractXMLPipe.java:94) at org.apache.cocoon.xml.AbstractXMLPipe.startElement(AbstractXMLPipe.java:94) at org.apache.cocoon.transformation.AbstractSAXTransformer.startTransformingElement(AbstractSAXTransformer.java:658) at org.apache.cocoon.transformation.SQLTransformer.start(SQLTransformer.java:765) at org.apache.cocoon.transformation.SQLTransformer.executeQuery(SQLTransformer.java:323) at org.apache.cocoon.transformation.SQLTransformer.endExecuteQueryElement(SQLTransformer.java:476) at org.apache.cocoon.transformation.SQLTransformer.endTransformingElement(SQLTransformer.java:738) at org.apache.cocoon.transformation.AbstractSAXTransformer.endElement(AbstractSAXTransformer.java:336) at org.apache.cocoon.components.sax.XMLTeePipe.endElement(XMLTeePipe.java:89) at org.apache.cocoon.components.sax.XMLByteStreamInterpreter.parse(XMLByteStreamInterpreter.java:100) at org.apache.cocoon.components.sax.XMLByteStreamInterpreter.deserialize(XMLByteStreamInterpreter.java:73) at org.apache.cocoon.components.pipeline.impl.AbstractCachingProcessingPipeline.processXMLPipeline(AbstractCachingProcessingPipeline.java:267) at org.apache.cocoon.components.pipeline.AbstractProcessingPipeline.process(AbstractProcessingPipeline.java:483) at org.apache.cocoon.components.treeprocessor.sitemap.SerializeNode.invoke(SerializeNode.java:120) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:46) at org.apache.cocoon.components.treeprocessor.sitemap.PreparableMatchNode.invoke(PreparableMatchNode.java(Compiled Code)) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java(Compiled Code)) at org.apache.cocoon.components.treeprocessor.sitemap.PipelineNode.invoke(PipelineNode.java:138) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java(Compiled Code)) at org.apache.cocoon.components.treeprocessor.sitemap.PipelinesNode.invoke(PipelinesNode.java:92) at org.apache.cocoon.components.treeprocessor.ConcreteTreeProcessor.process(ConcreteTreeProcessor.java:234) at org.apache.cocoon.components.treeprocessor.ConcreteTreeProcessor.process(ConcreteTreeProcessor.java:176) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:243) at org.apache.cocoon.components.treeprocessor.sitemap.MountNode.invoke(MountNode.java:117) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:46) at org.apache.cocoon.components.treeprocessor.sitemap.PreparableMatchNod -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
