Converting ResultSet to XML

Oftentimes, we need to convert ResultSets to XML for transferring data across different applications. Here is very simple code that transforms ResultSets into XML.

 import java.sql.*;import*;public class XMLWriter{    public String generateXML(final ResultSet rs) throws SQLException    {        final StringBuffer buffer = new StringBuffer(1024*4);        if(rs == null) return "";        if(! return "";        buffer.append("
");        buffer.append("
");        ResultSetMetaData rsmd = rs.getMetaData();        int colCount = rsmd.getColumnCount();        for(int id=0;; id++)        {            buffer.append("	
");            for(int i = 1; i <= colCount; i++)            {                int type = rsmd.getColumnType(i);                buffer.append("		");                buffer.append(getValue( rs, i, type));                buffer.append("
");            }            buffer.append("	
");        }        buffer.append("");        rs.close();        return buffer.toString();    }    /**     * This method gets the value of the specified column     */    private String getValue(final ResultSet rs, int colNum, int type)throws SQLException    {        switch(type)        {            case Types.ARRAY :            case Types.BLOB :            case Types.CLOB :            case Types.DISTINCT :            case Types.LONGVARBINARY :            case Types.VARBINARY :            case Types.BINARY :            case Types.REF :            case Types.STRUCT :                return "undefined";            default :            {                Object value = rs.getObject(colNum);                if(rs.wasNull() || (value == null))                    return ("null");                else                    return (value.toString());            }        }    }}
