Updating information using sqlplus

Question

I cannot figure out why my code will not update my database. Using
sqlplus. I can type it into the database myself, but I cannot seem to pass the information through my jsp program
String type = request.getParameter("studentSelection");
String student = request.getParameter("student");
String change = request.getParameter("change");
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
conn = DriverManager.getConnection(jdbcURL, userpasswd);
stmt= conn.createStatement();
String upd = "UPDATE STUDENT SET FNAME ='"+change+"' WHERE SSN ='"+student+"'";          
stmt.executeUpdate(upd);
Here is my database structure, everything is a char of varchar:
SSN FNAME MI LNAME BDATE SEX PHONE
111111111 BOB J JONES 01-02-84 M 5551111

Hi,
are u getting any errors? If not then try to print the number of rows that are updated as executeUpdate will return the number of rows updated. Also since you have a where condition try and print the query to check if the where condition is being satisfied and then execute this query in your sqlplus to see if the query actually runs in sqlplus.
hope this helps
