How to use clob object

Question

I read the serval topic of clob, but I can't read clob in jsp also.
my code is:
<%@ page language="java" import="java.sql.*,java.util.* "%>
<%@ include file="conn.jsp"%>
<%@ page import="oracle.sql.*,oracle.jdbc.*" %>
<%
try {
Class.forName(URL);
Connection conn=DriverManager.getConnection(METHOD,USER,PWD);
Statement stmt=conn.createStatement();
String sql_str="select * from pub_01";
ResultSet rs = stmt.executeQuery(sql_str);
if (rs.next()) {
new_pos=DBMS_LOB.INSTR(rs.Content,CHR(10),pos);
Str=DBMS_LOB.SUBSTR(rs.Content,new_pos-pos, pos);
pos=new_pos+1;
CLOB clob=((OracleResultSet)rs).getCLOB(2);
String str=clob.getSubString(1,10);
/*if(PreviewObj != null){
oracle.sql.CLOB MyClob = (oracle.sql.CLOB)PreviewObj;
System.out.println(
MyClob.getSubString(1, (int)MyClob.length())) ;
// out.println(trans.hz_format(rs.getString("content"),1));
rs.close();
conn.close();
catch (SQLException e) {
out.print("SQL Exception occur. Error: ");
out.print(e.getMessage());
%>
but can't execute. error is:
SQL Exception occur. Error: ORA-12535: TNS: ????

oDataTable.Rows.Add 2
For ii = 0 To oDataTable.Columns.Count - 1
    For jj = 0 To oDataTable.Rows.Count - 1
