my bean:
=======
package app;

import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import java.io.*;
import java.sql.*;

public class db_connection {

public static String queryExecute(String mrn, Connection conn)
throws pcSQLException {

try {
String querytext = null;
String strQuery = "select mrn from qdsn.procedurea where mrn = '" + mrn + "' ";
Statement stmt = conn.createStatement();
System.out.println("conn = " + conn);
ResultSet rset = stmt.executeQuery(strQuery);

while (rset.next()) {
querytext = rset.getString(1);
System.out.println("this is result from bean" + querytext);
return querytext;
}//end while

} catch (Exception e) {
throw new pcSQLException();
}//end catch
return null;
}
}//end db_connection

Error Message while trying to compile:
======================================

queryExecute() in app.db_connection cannot be applied to (java.lang.String,java.sql.Connection)
[javac] selectstr = db_connection.queryExecute(mrn, conn);
[javac] ^
[javac] 1 error

Please help!!!
Thanx in advance

[parthiban subramaniam]

cant see anything worng with the code mate
unless you have a old version of db_connection class which had the method queryExecute()
this should not happen,
clear out the classes and try to recompile thos whole lot from the scratch

hope that helps
cheers,
