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
