JasperException/ServletException when using useBean...help!!I'm using an HTML form to get some input from the user and then send
the input to a database. Everything was working fine, but then I
decided to use a drop down box for one of the input methods in the form
instead of a checkbox and now I keep getting a JasperException and a
SErvletException.
here is the FORM code:
<form method="POST" action="addtohave.jsp">
<p align="center">
ISBN<sup>*</sup>: <INPUT TYPE=TEXT name="isbn"
size="13" maxlength="13">
Price: <input type=TEXT name="price" size="7"
maxlength="7">
I am willing to:
<select name="transtype">
<option value="sell">Sell it</option>
<option value="trade">Trade it</option>
<option value="both">Sell or Trade</option>
</select>
Condition:
<select name="condition">
<option value="poor">Poor</option>
<option value="fair">Fair</option>
<option value="average">Average</option>
<option value="good">Good</option>
<option value="excellent">Excellent</option>
</select>
****************************************
************************************
*************
the following is my class:
package bkwrmspackage;
public class addToHave {
String isbn;
String price;
String transtype;
String condition;
public void setIsbn(String value){
isbn = value;
}
public void setPrice(String value){
price = value;
}
public void setTranstype(String value){
transtype = value;
}
public void setCondition(String value){
condition = value;
}
public String getIsbn(){
return isbn;
}
public String getPrice(){
return price;
}
public String getTranstype(){
return transtype;
}
public String getCondition(){
return condition;
}
}
****************************************

and now the jsp page that is doing all the work after the form is
submitted:
<%@ page

bkwrmspackage.*"
%>
<jsp:useBean id="input" class="bkwrmspackage.addToHave"

}
catch (SQLException s)

I have no idea what the problem is...as you can see the error output is
not very helpful. any help here would be greatly appreciated. I
remembered to recompile my class again after modifying it and I've
triple checked that I changed all the variable names where needed.
Thanks in advance,
