Always getting error- no result defined for action and result success

[MaheshS Kumbhar]

I have following struts.xml
The action "createAccount" is getting fired but its chained action "login" is not getting fired and getting error "no result defined for this action and result success"
I am not able to figure out what is the issue?
Can anyone please help me in this?

<struts>
<constant name="struts.devMode" value="true"/>
<package name="basicStruts" extends="struts-default">
<action name="createaccount" class="action.createAccount">
<result type="chain">login</result>
</action>

<action name="login" class="action.login">
<result type="chain">dashboard</result>
</action>

<action name="dashboard" class="action.dashboard">
<result>/dashboard.html</result>
</action>
</package>

</struts>
