facing problem in reading & writing the files

Try using the following pattern:


//read


BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream(fileNameIn), "ISO8859_2")));

// write

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileNameOut), "ISO8859_2")));

I am using the same but facing problem when applying xslt to the xml the resulting xml have default encoding set to UTF-8 how I can change it during transformation?

Not sure. Can you post some code around the area you're doing that?

public String map(MapperParams params) throws MapperException, CBSException {
      logger.debug("Executing map");
      logger.debug("mapping parameters" + params.toString());
      String fileExtension = null;
      this.xslMappingFile = params.getXslMappingFile();
      this.inputFile = params.getInputFile();
        logger.debug("this.inputFile....."+inputFile);
      String fileType = "";
      switch (params.getFileType()) {
            case MapperParams.WIT : {
         fileType="_WIT";
         fileExtension = ".xml";
                  break;
            }
            case MapperParams.MIB : {
                  fileType="_MIB";
         fileExtension = ".txt";
                  break;
            }
            default :
                  break;
       }

      this.witXmlFile = inputFile + fileType + fileExtension;

      logger.debug("the new output "+fileType+" XMLFile " + this.witXmlFile);

      }
  the output xml contains <?xml version="1.0" encoding="UTF-8"?> while I want to put it as <?xml version="1.0" encoding="ISO-8859-2"?>

Have a go with this. If it doesn't work, try tweaking the encoding string:

transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "ISO8859-2");

Still same output I mean in the resulting xml file <?xml version="1.0" encoding="UTF-8"?>  is coming not <?xml version="1.0" encoding="ISO-8859-2"?>

You're setting it immediately after this i assume?:

>>transformer = TransformerFactory.newInstance().newTransformer(xslDomSource);

yes

try {
         transformer = TransformerFactory.newInstance().newTransformer(xslDomSource);
            logger.debug("b4************************************transformer.setOutputProperty");
             transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "ISO8859-2");
      }

Try iterating the properties before and after.

sorry could not get you.

During  xmlDoc = dBuilder.parse(fs); the xmlDoc contains <?xml version="1.0" encoding="UTF-8"?>   while in the fs it is <?xml version="1.0" encoding="ISO-8859-2"?> .

I think if I can change here then it may give the correct result but how I can change do not know.

Presumably you're transforming using http://java.sun.com/j2se/1.4.1/docs/api/javax/xml/transform/Transformer.html#transform(javax.xml.transform.Source, javax.xml.transform.Result)

Try setting the encoding in the Result

Thanks  a Lot for your responses.

Yes the code is

DOMResult result = new DOMResult();
               try {
                        logger.debug("xmlDomSource..."+xmlDomSource.toString());
                        logger.debug("result..."+result.toString());
                        try{
                           logger.debug("result.getNode()..."+getDocumentAsString((Document)result.getNode()));
                     }catch(Exception e)
                     {
                        logger.debug("Exception in result.getNode()...");
                     }
                  transformer.transform(xmlDomSource, result);
               }
but how I can set the encoding in the result. there is no method for this it seems.

That's probably because you're using a DOMResult - until things are moved out of memory and into a renderable form, encoding is not really an issue. If you were to use a StreamResult, you could set the encoding.

even in StreamResult there is no such method for changing the encoding

BufferedWriter br = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileNameOut), "ISO8859_2")));
StreamResult out = new StreamResult(br);

Yes this finally I am doing but my main point is that the output file should have the prolog of <?xml version="1.0" encoding="ISO-8859-2"?> not <?xml version="1.0" encoding="UTF-8"?> . This what you wrote will give the output charset as ISO... but not what I need in the prolog. My requirement is to further read the resulting xml & then do something but as the resulting xml have ISO.. char set & the prolog have UTF-8 so I get the exception.

OK - got you. What about setting the prolog using the xsl?

<?xml version="1.0" encoding="ISO-8859-2"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="ISO-8859-2" indent="yes"/>
      <xsl:template match="/">

I am using the above prolog. Though the XSLT I have written have all english character's but still I used <?xml version="1.0" encoding="ISO-8859-2"?>

but no use since getting the exception.

Is that not working then?

yes it is not working..
