Exception running XSInstance.java

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
  If I run XSInstance with the latest code (svn 1766) and the file trunk/xml/xsds/purchaseOrder.xsd I get the exception:
Exception in thread "main" java.lang.NullPointerException
    at jlibs.xml.sax.helpers.MyNamespaceSupport.declarePrefix(MyNamespaceSupport.java:104)
    at jlibs.xml.sax.XMLDocument.declarePrefix(XMLDocument.java:94)
    at jlibs.xml.sax.XMLDocument.toQName(XMLDocument.java:112)
    at jlibs.xml.sax.XMLDocument.addAttribute(XMLDocument.java:232)
    at jlibs.xml.xsd.XSInstance$XSSampleVisitor$2.preProcess(XSInstance.java:286)
    at jlibs.xml.xsd.XSInstance$XSSampleVisitor$2.preProcess(XSInstance.java:1)
    at jlibs.core.graph.WalkerUtil.walk(WalkerUtil.java:40)
    at jlibs.xml.xsd.XSInstance.generate(XSInstance.java:103)
    at jlibs.xml.xsd.XSInstance.main(XSInstance.java:704)

This does work with svn rev. 1753 so it is an error that was introduced with 
the changes between those builds. 

What is the expected output? What do you see instead?
Should generate the XML

What version of the product are you using? On what operating system?
Windows, but I ran the test just in Java with the XSIntance

Please provide any additional information below.
I appreciate your solution and it looks like it could be very helpful to us. 
Thanks for maintaining it.

Wow, quick turn around on that fix. It's working great now. Thanks for your 
useful code.

thanks

the problem is XSObject.getNamespace() can return null string as per its javadoc
but jdk's xml apis never expect null for namespaceuri

thus problems arise when we use to libraries which don't conform.
