Nils-H,
I noticed some error in my struts-view.xml. It now looks like:
<struts>
<package name="view" extends="struts-portlet-default"
namespace="/view">
<action name="index">
<result name="success">/WEB-INF/view/index.jsp</result>
</action>
<action name="longProcess3" class=
"org.apache.struts2.showcase.wait.LongProcessAction">
<interceptor-ref name="defaultStack"/>
<interceptor-ref name="execAndWait">
<param name="delay">3000</param>
<param name="delaySleepInterval">1000</param>
</interceptor-ref>
<result name="wait">/WEB-INF/view/wait.jsp</result>
<result name="success">/WEB-INF/view/complete.jsp</result>
</action>
</package>
</struts>
wait.jsp has
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<meta http-equiv="refresh" content="5;url=<s:url includeParams="all"/>"
/>
</head>
<body>
<p style="border: 1px solid silver; padding: 5px; background: #ffd;
text-align: center;">
We are processing your request. Please wait.
</p>
<p/>
You can click this link to <a href="<s:url includeParams="all"/>">
refresh</a>.
</body>
</html>
It's fine if it goes straight to success page. The problem is with wait
page. The new exception is:

Could this be caused by the portlet container?
Thanks.

I have never tested the execute and wait stuff, so I don't really know
how it works. But from reading the code for the interceptor, and
reading the stack trace, I would guess that this happens because the
default "wait" result is invoked and is not a result type that is
supported in a portlet. You could try configuring a result for "wait"
for the action explicitly. If you still have problems, please provide
the relevant configuration snippets.
