Statement parameter 1 is not set

[Gayani Kanchana]

i am working on a web application which is developed using netbeans 5.5(using jdk 1.6).Currently the same application runs on Sun application server without errors. When i tried to run using apache tomcat server(Tomcat 5.5) I get errors.

There is a drop down list in my program
When I run the project, I get the following error.

Exception Details: java.sql.SQLException
Statement parameter 1 not set.

I have used Prepared Statements in my program.
Database is MySQL 4.1. i have used mysql-conncetor-java-3.1 Does this cause a problem?Please help me.
thanks

Employ basic debugging techniques to try and find out why the JDBC statement is failing. Obviously, one of the parameters to the statement is not being set.
