NoSuchMethodError/NullPointerException with Lotus Notes 6

Hi,

I am trying to use the Batik transcoder API as part of a Lotus Notes 6 Java agent. The code is pretty much the same as
the SaveAsJpeg example in the documentation and it all works fine until I actually try and transcode the TranscodeInput
into the TranscoderOutput, which gives me the following error:

java.lang.NoSuchMethodError: org.w3c.dom.DOMImplementation: method
createDocument(Ljava/lang/String;Ljava/lang/String;Lorg/w3c/dom/DocumentType;)Lorg/w3c/dom/Document; not found
      at org.apache.batik.dom.util.SAXDocumentFactory.createDocument(Unknown Source)
      at org.apache.batik.dom.svg.SAXSVGDocumentFactory.createDocument(Unknown Source)
      at org.apache.batik.dom.svg.SAXSVGDocumentFactory.createDocument(Unknown Source)
      at org.apache.batik.transcoder.XMLAbstractTranscoder.transcode(Unknown Source)
      at SaveAsJPEG.createJPEG(SaveAsJPEG.java:37)
      at JavaAgent.NotesMain(JavaAgent.java:32)
      at lotus.domino.AgentBase.runNotes(Unknown Source)
      at lotus.domino.NotesThread.run(NotesThread.java:208)

Although Lotus Notes natively uses IBM's XML4j.jar, adding XMLResourceDescriptor.getXMLParserClassName() to the code
returns the following:

org.apache.crimson.parser.XMLReaderImpl

If I remove XML4j.jar from my Notes installation, the agent fails on the same line but  for a different reason:

java.io.IOException: java.lang.NullPointerException
      at org.apache.batik.dom.util.SAXDocumentFactory.createDocument(Unknown Source)
      at org.apache.batik.dom.svg.SAXSVGDocumentFactory.createDocument(Unknown Source)
      at org.apache.batik.dom.svg.SAXSVGDocumentFactory.createDocument(Unknown Source)

      at JavaAgent.NotesMain(JavaAgent.java:32)
      at lotus.domino.AgentBase.runNotes(Unknown Source)
      at lotus.domino.NotesThread.run(NotesThread.java:208)
org.apache.batik.transcoder.TranscoderException: null
Enclosed Exception:
java.lang.NullPointerException
      at org.apache.batik.transcoder.XMLAbstractTranscoder.transcode(Unknown Source)
      at SaveAsJPEG.createJPEG(SaveAsJPEG.java:37)
      at JavaAgent.NotesMain(JavaAgent.java:32)
      at lotus.domino.AgentBase.runNotes(Unknown Source)
      at lotus.domino.NotesThread.run(NotesThread.java:208)

Again, XMLResourceDescriptor.getXMLParserClassName() returns the following:

org.apache.crimson.parser.XMLReaderImpl

Has anyone got any ideas? If it helps, Lotus Notes creates a new classpath each time an agent is run, in the following
order:

1) Any classes or archives added to Lotus Notes ini file (I have none)
2) Any default classes or archive files Notes uses (this is where XML4j.jar gets picked up from)
3) And classes or archive files attached to the agent itself (this is where all the Batik files are)

Thanks,

Karl

Re: W3C "valid" SVG documents

Posted by Jane Singer <js...@cc.huji.ac.il>.

OK, I typed that  into the example by mistake, it is not in the document.

I guess my general question is, are the documents created by the
org.apache.batik.dom.svg.SVGDocumentFactory valid W3C documents?
I'm having a lot of trouble combining W3C component with those created by
batik and others. It seems most of my problems have to do with the order I
list things in the classpath.
Jane

Re: W3C "valid" SVG documents

Posted by Vincent Hardy <vi...@sun.com>.

Hello Jane,

Try your file without the trailing </xml>. It should work better.
Vincent.
