How do make Spring access dropdown box values.

I am trying to make Spring MVC get the value of one of my dropdowns.

org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/view/dateRange.jsp at line 28

25: <tr>
26:     <td>
27:         <div align="right">Last Month Of Full Data:</div></td>
28:         <td><form:select path="Lst_mnt">
29:             <option value="1">January</option>
30:             <option value="2">February</option>
31:

All that I am doing its to get the value into Spring not build the dropdown

First of all, you are not using the <form:select> properly. You have two options:

  • use a simple <select> tag with <option> tags inside, and give it a name the corresponds to the model object field (Lst_mnt in this case, but avoid that underscore)
  • use <form:select> with a Map in which you can fill the keys and values for the select

Thus you will show the values. Then:

  • If you want to get the selected value - it will be filled in the model object when the form is submitted, so you will have it in your controller method.
  • If you want to manipulate them in the browser - use javascript

If you remove the td that includes the form:select does your form work correctly?

Is Lst_mnt a property of the form backing bean? Also is it an integer or string field?

Maybe you can post the whole form?
