In my struts2 xml file, I see this interceptor def:
<interceptors>
<interceptor-stack name="dividendinterceptorstack">
<interceptor-ref name="servletConfig" />
<interceptor-ref name="modelDriven" />
</interceptor-stack>
But where is the actual class defined for dividendinterceptorstack? it is not in the xml.
Interceptor stacks are not classes, they are collections of interceptors run in a specific order.
dividendinterceptorstack is a stack (collection) of interceptors.
If you can't find this stack definition - What does your package enclosing the above snippet extend from? Look in the package's
hierarchy.

i just picked this up from struts-dafault.xml file located in struts core jar so you can see interceptor ref name has already been defined so we are just refereeing them when we are declaring our own stack

<interceptor-stack name="DefaultTEST">
<interceptor-ref name="exception" />
<!-- some more interceptors go in here -->
<interceptor-ref name="debugging" />
</interceptor-stack>
<default-interceptor-ref name="DefaultTEST" />
<action name="welcome">
<result type="tiles">WELCOME_PAGE</result>
</action>
<action name="">
<result ...>...</result>
</action>
... <!-- more actions -->
So my question is how to override the default interceptor stack so that for welcome action some other interceptors (or interceptor stack) can be loaded while the default one is not.
You can override the interceptors config if you reference an interceptor or interceptors stack in the action config explicitly.
<action name="welcome">
<interceptor-ref name="defaultStack" />
<result type="tiles">WELCOME_PAGE</result>
</action>
Only defaultStack will be executed for welcome action. Other actions that don't override the interceptors config in this package will use DefaultTEST because it's configured as default.
<interceptors>
<interceptor-stack name="appDefault">
<interceptor-ref name="defaultStack">

Try to configure interceptor for individual action as given below.
<action name="yourAction" class="com.YourActionClass">
<interceptor-ref name="tokenSession"></interceptor-ref>
<interceptor-ref name="defaultStack"></interceptor-ref>
<result name="success">/success.jsp</result>
<result name="input">/update.jsp</result>
</action>
I am getting like "WARNING: Could not find token name in params."
In Struts.xml
<interceptors>
<interceptor name="entityInterceptor" class="entity.jpa.EntityInterceptor"/>
<interceptor name="sessionInterceptor" class="env.actionitems.struts.SessionInterceptor"/>
<interceptor-stack name="entityStack">
<interceptor-ref name="entityInterceptor"/>
<interceptor-ref name="sessionInterceptor"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="defaultStack">
</interceptor-ref>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="entityStack"></default-interceptor-ref>
<action name="*acegitran*jsp*pkg*create*dcode*" method="{1}" class="env.transactions.{3}.{4}">
<interceptor-ref name="token"/>
<interceptor-ref name="entityStack"/>
<result name="invalid.token">Transaction.{2}iport{5}create</result>
<result name="success" type="tiles">Transaction.{2}iport{5}create</result>
<result name="error" type="tiles">Transaction.{2}iport{5}create</result>
<result name="input" type="tiles">Transaction.{2}iport{5}create</result>
</action>
In JSP
<s:token name="clientToken"/>
Any other parameters should be passed in struts.xml to solve.
I had a similar problem. You might want to try changing "invalid.token" to "invalid.clientToken" in the Struts.xml file
eg
result name="invalid.clientToken"
Please remember that the Struts.xml file will only take effect after the server is restarted!
Hope that helps
I am using Struts 2-Spring framework in my assignment.
I have defined a bean in struts 2 action class
One interceptor for checking authorisation before executing every action.
The bean is used for defining controls like textfield, Radio button, etc on jsp page.
On submit of this page control goes properly to defined action class, but finds bean object as null in action class. Hence unable to perform futher operations.
Removing interceptors works fine.
Any pointer will be appreciated.
I haven't defined stack for interceptors defined in struts.xml.
After defining below stack in struts.xml its works fine:
<interceptors>
<interceptor-stack name="applicationStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="scopedModelDriven"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="multiselect"/>
<interceptor-ref name="staticParams"/>
<interceptor-ref name="actionMappingParams"/>
<interceptor-ref name="params">
<param name="excludeParams">dojo\..*,^struts\..*</param>
</interceptor-ref>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="debugging"/>
<!-- User defined interceptor -->
<interceptor-ref name="contextSecurityInterceptor"/>
</interceptor-stack>
i have a problem with Struts2
This is my action configuration, before executing the roleDete in the Action, the interceptor is call, but after this, the values of the input are lost, there is no id to delete, if i remove the interceptor then the id to delete exist, could some one guide me to solve this?
<action name="roleDelete" method="roleDelete" class="com.webapp.role.action.RoleAction">
<interceptor-ref name="validateUser"/>
<result name="input" type="tiles">usertypePage</result>
<result name="success" type="redirect">usertypeForm</result>
</action>
Thanks
It sounds like you've defined a custom validateUser interceptor stack that doesn't include a required Struts 2 interceptor. By default, Struts 2 invokes the following interceptors on every request unless you define your own stack (as you've done):
<interceptor-stack name="defaultStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="debugging"/>
<interceptor-ref name="scopedModelDriven"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="multiselect"/>
<interceptor-ref name="staticParams"/>
<interceptor-ref name="actionMappingParams"/>
<interceptor-ref name="params">
<param name="excludeParams">dojo\..*,^struts\..*</param>
</interceptor-ref>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
</interceptor-stack>
My advice would be to go through the above list and add them back in one at a time until you figure out which you need to properly populate your request variable. You can read more about interceptors in the Struts 2 docs.
<interceptors>
<interceptor name="vendorStoreInterceptor" class="br.org.myapp.actions.interceptors.VendorStoreInterceptor"></interceptor>
<interceptor-stack name="defaultStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="debugging"/>
<interceptor-ref name="scopedModelDriven"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="multiselect"/>
<interceptor-ref name="staticParams"/>
<interceptor-ref name="actionMappingParams"/>
<interceptor-ref name="params">
<param name="excludeParams">dojo\..*,^struts\..*</param>
</interceptor-ref>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<param name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
</interceptor-stack>
<interceptor-stack name="mainStack">
<interceptor-ref name="vendorStoreInterceptor"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="mainStack"/>

Use that. You have to include your interceptor and the defaultStack after (watch the last 'interceptor-stack' with my 'vendorStoreInterceptor' and the 'defaultStack').
That's it!
