Good morning,
your interceptor stack doesn't appear to be complete.
By adding the following codes into struts.xml, no exception anymore. But
the action page does *not* go to wait.jsp; but stays on the original
action class page.
<interceptor name="execAndWait"
class="com.opensymphony.webwork.interceptor.ExecuteAndWaitInterceptor"/>
Do I need to explicit saying the following in struts.xml?
<interceptor-stack name="completeStack">
<interceptor-ref name="prepare"/>
<interceptor-ref name="servlet-config"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="model-driven"/>
<interceptor-ref name="component"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="static-params"/>
<interceptor-ref name="params"/>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation"/>
<interceptor-ref name="workflow"/>
</interceptor-stack>
Thanks a lot!
Emi
Below is a code-frag from the following link:
http://struts.apache.org/2.2.1/docs/execute-and-wait-interceptor.html
<action name="someAction" class="com.examples.SomeAction">
<interceptor-ref name="completeStack"/>
<interceptor-ref name="execAndWait">
<param name="delay">1000<param>
<param name="delaySleepInterval">50<param>
<interceptor-ref>
<result name="wait">longRunningAction-wait.jsp</result>
<result name="success">longRunningAction-success.jsp</result>
</action>

You didn't add exec-and-wait, you replaced your entire interceptor stack with
just the exec-and-wait interceptor.
Can you provide more information please?

I setup almost the same example. The differences
. my action class has bean from spring
. use tiles for "adm" result

Hello,
One action class to send emails to 50 users. Before action is done, I'd like to
show a waiting page.
When I added execAndWait shown as the following:
<action name="*ProcessAction" method="{1}" class="ProcessAction">
<interceptor-ref name="execAndWait">
<param name="delay">2000</param>
<param name="delaySleepInterval">500</param>
</interceptor-ref>
<result name="wait">/wait.jsp</result>
<result name="adm" type="tiles">browse_action1</result>
...
I got the following Error message returned.
Could someone help what is missing?
I found examples about progressbar + fileupload, but what about waiting for
sending emails, is there a online doc about this?
Thanks a lot!
Emi
