Yes, exactly.

Assuming editDoc.jsp contains an html:form tag which submits to 
/EditDoc, you don't need any additional configuration to use the form in 
editDoc.jsp. The html:form tag will automatically create a scripting 
variable 'docForm'.

However, to pre-populate the form bean in EditDocAction, you do need the 
extra configuration: you need to tell Struts to provide the form bean to 
the action. To do that, just add 'name="docForm"' in the /EditDoc 
mapping, just as you did for the /ChangeDoc mapping.

You can then use the code you wrote above to initialise the form.
