Error when call webservice on servlet

Question

Hi All,
I'm having a problem when calling webservice inside the servlet on the WebLogic environment.
My code:
* Webservice:
package ws;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import javax.naming.NamingException;
import javax.sql.DataSource;
@WebService
public class getData {
public getData() {
super();
@WebMethod
public String getHello() {
return "HELLO HELLO";
private Connection getConn() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup("jdbc/hnxwebsite");
//System.out.println("POOL !!!!");
Connection con = ds.getConnection();
con.setAutoCommit(false);
return con;
@WebMethod
public String getIndexData(@WebParam(name="param") String param) {
StringBuffer sb = new StringBuffer();
String sql =
"Select * From idx_index_info iii where iii.index_code= ?";
Connection con = null;
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
con = getConn();
pstmt = con.prepareStatement(sql);
pstmt.setString(1, param);
rs = pstmt.executeQuery();
int columnCount = rs.getMetaData().getColumnCount();
Object val;
while (rs.next()) {
for (int i = 1; i < columnCount; i++) {
//System.out.println(i);
val = rs.getObject(i);
if (val != null)
sb.append(val.toString() + "\n");
} catch (SQLException e) {
e.printStackTrace();
} catch (NamingException e) {
e.printStackTrace();
} finally {
try {
if (rs != null)
rs.close();
if (pstmt != null)
pstmt.close();
if (con != null)
con.close();
} catch (Exception e) {
e.printStackTrace();
String str = sb.toString();
int len = str.length();
//System.out.println("LENGTH >>>>"+len);
return str;
public static void main(String[] arg) {

I'm no webservices/servlet expert , but can you check the obvious out here -
javax.xml.ws.WebServiceException: com.ctc.wstx.exc.WstxIOException: Exceeding stated content length of 228
at ......
at hnx.wsClient.procWeb(wsClient.java:75)+ // check if you are passign something thats more than 228 chars
at hnx.getIndex.doGet(getIndex.java:40)
