Store&read chinese characters in MS SQL server 2000 using Java

Question

Hi,
I have a problem to store Chinese characters in MS SQL Server 2000, storing question marks(??????) instead of Chinese characters
I am using JSF framework, SUN APPLICATION Server 9.1 , MS SQL Server 2000 server and Microsoft data source driver class (com.microsoft.sqlserver.jdbc.SQLServerDataSource) to connect db.
I have one solution:
IN JSP:
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
and
In database column type should “nvarchar” in place of varchar
while inserting or updating the same need to add ‘N’ prefix with the value like insert into client(Name, Id ….) values (N+)
the above is working fine but the problem is here i have already defined database with 100s of tables I cant change database tables as well as queries
Thanks,
Sathi

I don't know any betterer option, than to copy the database tabels redefining the Chinese data fields as nvarchar.
To be frank I had also problems writing to a html file Chinese text stored in MS SQLServer 2000 nvarchar fields.
The following worked:'
     public String getEncodedData(ResultSet resultSet, int columnIndex, String charset)
     throws SQLException
          //final String methodName = "getEncodedData";
          InputStream binaryStream =resultSet.getBinaryStream(columnIndex);
          String readStringFromStream=readStringFromStream(binaryStream, charset);//UTF_16LE);
          return readStringFromStream;
     public String readStringFromStream(InputStream inputStream, String charset) {
          final String methodName = "readStringFromStream";
          StringBuffer buffer = new StringBuffer();
          try {
               int ch;
               InputStreamReader isr = new InputStreamReader(inputStream, charset);
               Reader in = new BufferedReader(isr);
               while ((ch = in.read()) > -1) {
                    buffer.append((char)ch);
               in.close();
               return buffer.toString();
          } catch (IOException exception) {
               Log.printError(this,methodName, exception);
               return null;
     }And writing it to file:
     public void writeEncodedStringToFile(String text, String filePath, String charset, boolean append){
          final String methodName = "writeEncodedStringToFile";
          OutputStreamWriter writer= null;
          try {
               FileOutputStream fileOutputStream = new FileOutputStream(filePath, append);
               writer = new OutputStreamWriter(fileOutputStream, charset);
               writer.write(text);
          } catch (IOException exception) {
               Log.printError(this,methodName, exception);
          }finally{
               try {
                    writer.close();
               } catch (IOException exception) {
                    Log.printError(this,methodName, exception);
