I believe your form bean type example.NameForm is proper. Please do check that first.

Second thing is in message-resources tag, you mentioned example/ApplicationResources. Change it to example.ApplicationResources. It may work.

One more thing which I didn't observed earlier was :

you used one tag called <action-mapping> and </action-mapping> which is not there in struts-config.

Change that to <action-mappings> and </action-mappings>

Check it now. All the best

In struts-config, Change the line

<action path="/Name" type="strutsapp.*.*.example.NameAction" name="nameForm">

to

<action path="/Name" type="example.NameAction" name="nameForm">

In jsp, change the line

<html:form action="Name" name="nameForm" type="example.NameForm">

to

<html:form action="Name.do" name="nameForm" type="example.NameForm">

and try.

In jsp, change the line
<html:form action="Name" name="nameForm" type="example.NameForm">
to
<html:form action="/Name" name="nameForm" type="example.NameForm">
