struts-config.xml:default for action tag input attribute

[Timothy Toe]

The input attribute specifies which jsp page the ActionServlet will forward the control to when there are errors. What happens if I omit this attribute ? What is the default behaviour ?

 
<struts-config>  
...
<!-- ========== Action Mapping Definitions ============ -->  
    <action-mappings>    
        <action   path="/submit"
                  type="com.company.SubmitAction"    
                  name="submitForm"                 
                  input="/submit.jsp"              
                  scope="request">    
            <forward name="success" path="/submit.jsp"/>              
        </action>  
    </action-mappings>
</struts-config> 

Thanks.

If no input is specified and there are validation errors, then an error is thrown.
Here is the rekevant code from the RequestProcessor:
String input = mapping.getInput();
if (input == null) {
if (log.isTraceEnabled()) {
log.trace(" Validation failed but no input form available");
}
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,
getInternal().getMessage("noInput",
mapping.getPath()));
return (false);
}
