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 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

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
