Well, I have made some progress... Without changing the Java code (a class that extends ActionSupport and implements ApplicationAware and ParameterAware) I tried a different JSP approach.Please post any details you have, and a sample app that shows the problem, if possible.
I now have testblog.jsp and testblog2.jsp: the former includes the latter as
<html><head><title></title></head><body>
<jsp:include page="testblog2.jsp">
<jsp:param name="lowerBoundDay" value="3" />
<jsp:param name="upperBoundDay" value="-1" />
</jsp:include>
</body></html>
and testblog2.jsp is:
<%@ taglib uri="WebWorkTags" prefix="webwork" %>
<webwork:action name="'content.BlogPostAction'">
</webwork:action>
With this arrangement, my BlogPostAction class can now see the parameters: the setParameters method gets called, and in the log I see:
[2003-02-07 16:38:44,457] DEBUG com.datafaber.action.content.BlogPostAction content.BlogPostAction - Action executing..
[2003-02-07 16:38:44,457] DEBUG com.datafaber.action.content.BlogPostAction content.BlogPostAction - doExecute - mParameters = {lowerBoundDay=[Ljava.lang.String;@50d45b, upperBoundDay=[Ljava.lang.String;@49105b}

[2003-02-07 16:38:44,807] DEBUG com.datafaber.action.content.BlogPostAction content.BlogPostAction - Action executed in 350 ms
The mParameters variable is set in the setParameters() method of BlogPostAction, of course.
So, in the end I'm happy that I got it to work, but I still feel I do not understand WebWork as much as I'd like. I thought that I could pass parameters to actions via the param tag, and obviously it appears that I was wrong. Could someone enlighten me as to why the following syntax does not work as I originally thought?
<%@ taglib uri="WebWorkTags" prefix="webwork" %>
<webwork:action name="'content.BlogPostAction'">
<webwork:param name="'lowerBoundDay'" value="3" />
<webwork:param name="'upperBoundDay'" value="-1" />
</webwork:action>
Dunno if it matters, the setup I'm currently running is WebWork 1.2.1 and Tomcat 4.1.12.
