I thank you, but I still get "Cannot retrieve definition for form bean null." XML now is:
<action path="/uidstart"
type="com.cisco.nm.uid.struts.action.UidAction">
<forward name="success" path="/engineresult.jsp"/>
</action>
I'm sure I'm modifying correct XML file because if I add
name="FRED"
attribute in <action> element, then the above error turns into "Cannot retrieve definition for form bean FRED"

Root cause:
<same as above>
struts-config.xml has:
<action path="/uidstart"
type="com.cisco.nm.uid.struts.action.UidAction"
scope="request"
validate="false">
<forward name="success" path="/engineresult.jsp"/>
</action>

Yes, you can definitely do this. Of course, you give up the automatic
stuff that Struts does for you (calling reset(), populating the
properties, and calling validate()) in this case.
