Direct Known Subclasses:

XPathProcessorException

public class XPathException

extends javax.xml.transform.TransformerException

This class implements an exception object that all XPath classes will throw in case of an error. This class extends TransformerException, and may hold other exceptions. In the case of nested exceptions, printStackTrace will dump all the traces of the nested exceptions, not just the trace of this object.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.
