    • resolveEntity

      public org.apache.xerces.xni.parser.XMLInputSource resolveEntity(org.apache.xerces.xni.XMLResourceIdentifier aResourceIdentifier) throws org.apache.xerces.xni.XNIException, IOException
      Implemented because of the XNI interface. The entity resolver tries to find the resource in the classpath. This interface imlementation allows this resolver to be used as either the standard EntityResolver or one that can be used by the Xerces XNI components. If the resource can't be found an exception is thrown
      Specified by:
      resolveEntity in interface org.apache.xerces.xni.parser.XMLEntityResolver
      Parameters:
      aResourceIdentifier - The resource identifier that should be resolved.
      Returns:
      The XMLInputSource of the resource if found. Never returns null.
      Throws:
      org.apache.xerces.xni.XNIException - Error resolving name instance
      IOException - Error loading XML schema
