I have been trying to make a java project. Its using Struts 2 tags. There is a button Update whenever it is to be clicked, it should update the values in the database.

But I am getting this error:

No result defined for action com.comviva.im.ui.action.sysadmin.CUGAction and result input

No result defined for action com.comviva.im.ui.action.sysadmin.CUGAction and result input

This means that you are lacking the mapping for the input result for this Action in your Struts.xml

The standard workflow

JSP -> Interceptor Stack -> Action

is breaking BEFORE reaching the Action, most likely by the ConversionError Interceptor (eg. sending a String to an Integer, for example), and it is returning back without even reaching the Action.

Read more on Struts2 INPUT result: how does it work? How are conversion / validation errors handled?

When trying to come back, it can't find where to go.

So you must define an input result type: 

<action name="CUGAction" class="com.comviva.im.ui.action.sysadmin.CUGAction">
    <result name="success">/your.jsp</result>
    <result name="input">/your.jsp</result>
</action>

Then print out the error in your JSP with <s:fielderror /> and with <s:actionerrors />, and try to figure out what is happening.

  • Just a note: from result configuration `Likewise if the name attribute is not specified, the framework will give it the name "success".` http://struts.apache.org/2.x/docs/result-configuration.html – Aleksandr M Nov 14 '12 at 13:46
  • I would not call that a bad practice, "Intelligent Defaults" instead. :) – Aleksandr M Nov 14 '12 at 14:21
