javax.el.PropertyNotFoundException: Property 'HelpGroupItems' not found on type com.aais.helpguides.HelpGuide

Question

When running my code on Tomcat, I receive the following error:

javax.el.PropertyNotFoundException: Property 'HelpGroupItems' not found on type com.aais.helpguides.HelpGuide.

I have checked the HelpGuide.java file to make sure I have the HelpGroupItems getter/setter methods defined correctly. I have checked both jsp files as well for any misspelling of the name. When showForm=true, the /updateForm will show up, but it is only when showForm is false or I hit the submit button from the updateForm do I run into this error. Any help would be appreciated.

It should be

<td>${helpguide.helpGroupItems}</td>

Start with lowercase the property, as your class is

public class HelpGuide
{
    private String helpGroupItems;
