Hi

I am trying to use AXIOMXPath in a statement such as this (using Axis2 version 1.0):

AXIOMXPath xpathExpression = new AXIOMXPath (xpathString);                        
OMElement node= (OMElement)xpathExpression.selectSingleNode(OM_message);

I have verified the XPath is valid.

But... I get the following error:

java.lang.NullPointerException
        at org.apache.axiom.om.xpath.DocumentNavigator.getDocumentNode(DocumentNavigator.java:603)
        at org.jaxen.expr.DefaultAbsoluteLocationPath.evaluate(DefaultAbsoluteLocationPath.java:97)
        at org.jaxen.expr.DefaultXPathExpr.asList(DefaultXPathExpr.java:98)
        at org.jaxen.BaseXPath.selectNodesForContext(BaseXPath.java:674)
        at org.jaxen.BaseXPath.selectNodes(BaseXPath.java:213)
        at org.jaxen.BaseXPath.selectSingleNode(BaseXPath.java:234)

Any suggestions would be appreciated.

Thanks,

Brian Bacsu
