Re: NoClassDefFoundError with SAXParser

[N. Ganesh Babu]

Hi Rishi,

I am new to XML parsing. I am using xmlvalid parser to do parsing of xml files. But I want to user Xerces java version. I have downloaded the binary file and unzipped. Can you please explain me the command for execution of this xml parser.

Thanks
Ganesh

Hello Everyone,

 

I have been using the Xerces J SAXParser for some time now.  I recently made a modification to my codebase, only to find that I am now getting a NoClassDefFoundError when I call the SAXParser.parse(InputSource in) method.

 

The xercesImpl JAR is still in my classpath.  My changes had nothing to do with how I am using the parser.  Furthermore, I am still able to set the handlers and features.

 

I would really appreciate any help you guys can give me in regards to solving this problem....Thanks in advance... Rishi

 

Here is the code segment:

 

            XMLReader parser = (XMLReader) Class.forName(DEFAULT_PARSER_NAME).newInstance();
            if (parser == null) {
                return false;
            }           
            parser.setContentHandler(mapStore);
            parser.setErrorHandler(mapStore);

 

            parser.setFeature("http://xml.org/sax/features/validation", setValidation);
            parser.setFeature("http://xml.org/sax/features/namespaces", setNameSpaces);
            parser.setFeature(
                "http://apache.org/xml/features/validation/schema",
                setSchemaSupport);

 

            InputStream byteIn;
 
            for (int i=0; i < fileList.length; i++) {
                String filePath = MyFileManager.getConfigFolder() + fileList[i];
                byteIn = new FileInputStream(filePath);

                if (byteIn == null) {
                    initException = new NonFatalParseException("Failed loading one or more configuration files.");
                }
                else {
                    InputSource in = new InputSource(byteIn);
                    parser.parse(in);
                    MyFileManager.addLoadedFiles(fileList[i]);
                    byteIn = null;
                    in = null;
                }
            }
            mapStore = null;
            parser = null;
            return true;
        }
        catch (Throwable e) {
            initException = new FatalParseException(e.getMessage());
            return false;
        }
