org.w3c.dom.DOMException: The current document is unable to create an element of the requested type (namespace: http://www.w3.org/2000/svg, name: spot). at org.apache.batik.dom.AbstractNode.createDOMException(Unknown Source) at org.apache.batik.dom.svg.SVGDOMImplementation.createElementNS(Unknown Source) at org.apache.batik.dom.svg.SVGOMDocument.createElementNS(Unknown Source) at mypackage22.KeyAccidentClient$4.run(KeyAccidentClient.java:349) at org.apache.batik.util.RunnableQueue.run(Unknown Source) at java.lang.Thread.run(Thread.java:534) Pls advice.
