I have the following dynamic form FillDetails.html:
If you select abandoned car in the dropdown and fill in values for the make and color the make and color do not get set in the bean! They are null. Why is this? My folder structure is TOMCAT_FOLDER/webapps/email/UserData.java, FillDetails.html, SaveData.jsp. There is also a WEB-INF folder with /classes/user/UserData.class.
I haven't used setProperty in that way since about 2001. Submitting a form to a JSP is no longer considered an acceptable practice.
Forms should be submitted to servlet controllers that process the data and delegate activities to the model as necessary. Then, the request is forwarded to a JSP to display the results of the operation.
The issue is that you have named your fields using names starting with an upper-case letter.
Try changing the names of your input controls on the html page: Make-->make and Color-->color and then see if it works.
By the Javabeans specification, properties/variables should start with a lower case letter, and class names should start with an upper case letter.
You need to follow this pattern in order for the java bean to be populated correctly with values coming from the JSP page.
