unusual errror:driver does not support function

Hi,
Here is a part of my code that should search for records and display the same in my jsp page. But it throws an unusual error that driver does not support this function.
<%
Connection con=null;
java.sql.PreparedStatement stmt=null;
ResultSet rs=null;
String table="";
int year=0;
String str="";
String user_login="";
String project_title="";
try
{

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc

dbc:mech_iit");
table=request.getParameter("table");
System.out.println(table);
year=Integer.parseInt(request.getParameter("list_year"));
System.out.println(year);
user_login=request.getParameter("user_login");
System.out.println(user_login);
if(table.equals("publication"))
{
str="select paper_title,year from publications where user_login=? and ([year]=?)";
}
else
if(table.equals("sponsored_project"))
{
str="select project_title,year from sponsored_projects where user_login=? and ([year]=?)";
}
if(table.equals("consultancy"))
{
str="select project_title,year from consultancy_projects where user_login=? and ([year]=?)";
}
else
if(table.equals("supervised_project"))
{
str="select project_title,year from projects_supervised where user_login=? and ([year]=?)";
}
else
if(table.equals("manual"))
{
str="select title,year from manuals where user_login=? and ([year]=?)";
}
else
if(table.equals("technical_report"))
{
str="select tech_title,year from tech_reports where user_login=? and ([year]=?)";
}
stmt=con.prepareStatement(str);
stmt.setString(1,user_login);
stmt.setInt(2,year);
rs=stmt.executeQuery(str);

while(rs.next())
{
project_title=rs.getString(1);
String year1=rs.getString(2);
//tech_title=rs.getString("tech_title");
//paper_title=rs.getString("paper_title");
System.out.println(project_title);
System.out.println(year);
out.println("<html>");
out.println(" ");
out.println(" ");
out.println("<p align=center>");
out.println("<b>"+"RECORDS"+"</b>");
out.println("</p>");
out.println("<table border=1 div align=center width=80% cellpadding=2 cellspacing=2>");
out.println("<tr>");
out.println("<td>");
out.println("<div align=center>");
out.println("<b>"+"<font face=Arial>"+"Title"+"</font>"+"</b>"+"</div>");
out.println("</td>");
out.println("<td>");
out.println("<div align=center>"+"<b>"+"Year"+"</b>"+"</div>");
out.println("</td>");
out.println("</tr>");
out.println("<tr>");
out.println("<td>");
out.println(project_title);
out.println("</td>");
out.println("<td>");
out.println(year);
out.println("</td>");
out.println("</tr>");
out.println("<tr>");
out.println("<td>");
out.println(project_title);
out.println("</td>");
out.println("<td>");
out.println(year);
out.println("</td>");
out.println("</tr>");
out.println("</table>");

}

}

catch(Exception ie)
{
System.out.println("jasu");
System.out.println("Exception:"+ie);
}
%>
like if i try to search for consultancy_projects for year 2001 an exception occurs that java.sql.SQLException that the driver does not support this function.

rs=stmt.executeQuery(str);

As you have specified the query in con.prepareStatement(str) function. So use rs=stmt.executeQuery(); function. I think this is the problem.
Let me know if there is anyother.

Moved to the JDBC forum.

i guess i got my solution ..tkx
