Description

this happens for example if the action in a html:form tag is not existing in the struts-config.xml

A reasons for this could be due to a typo.

Suggestion: if the ForwardConfig lookup in struts-config.xml results in "null", please cite the action string that was used for the lookup .

The below error message is currently not particularly helpful. Or at least mention something like, "please check your struts-config.xml"
