Raising Exceptions in XSLT mapping.?

Question

Hi,
When there is an mapping exception, in UDF, i raise an exception...
Similar is the case with Java & ABAP mappings.
Now, How do i raise mapping exceptions in XSLT mapping (Java & ABAP)..?

You could use Java enhancement, but instead of just adding info to the trace, you could raise a real exception, using an ErrorHandler object. Ive successfully worked with the one below (not with XSLTs, tho, but I dont see why it shouldnt work.
import java.util.Map;
import org.xml.sax.ErrorHandler;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import com.sap.aii.mapping.api.AbstractTrace;
import com.sap.aii.mapping.api.StreamTransformationConstants;

public class MappingErrorHandler implements ErrorHandler {
     private static AbstractTrace trace = null;
     public MappingErrorHandler(Map param) {
          trace =
               (AbstractTrace) param.get(
                    StreamTransformationConstants.MAPPING_TRACE);
     public void warning(SAXParseException exception) throws SAXException {
          trace.addInfo(
               "**Parsing Warning**n"
                    + "  Line:    "
                    + exception.getLineNumber()
                    + "n"
                    + "  URI:     "
                    + exception.getSystemId()
                    + "n"
                    + "  Message: "
                    + exception.getMessage());
          throw new SAXException("Warning encountered");
     public void error(SAXParseException exception) throws SAXException {
          trace.addInfo(
               "**Parsing Error**n"
                    + "  Line:    "
                    + exception.getLineNumber()
                    + "n"
                    + "  URI:     "
                    + exception.getSystemId()
                    + "n"
                    + "  Message: "
                    + exception.getMessage());
          throw new SAXException("Error encountered");
     public void fatalError(SAXParseException exception) throws SAXException {
          trace.addInfo(
               "**Parsing Fatal Error**n"
                    + "  Line:    "
                    + exception.getLineNumber()
                    + "n"
                    + "  URI:     "
                    + exception.getSystemId()
                    + "n"
                    + "  Message: "
                    + exception.getMessage());
          throw new SAXException("Fatal Error encountered");
