Hi Mark,
I've tried this now, but I'm unable to access the data from the JSP. In the
struts.xml configuration file, the action involved is configured this way:
<action name="Search_*" method="{1}" class="crosseyed.Search">
<result name="input">/crosseyed/Search.jsp</result>
<result type="redirect-action">Display</result>
</action>
I.e. Search.jsp -> Search action class -> Display.jsp
On the Search.jsp page, one can enter some keywords. The Search action is
then executed, after which one is redirected to the Display.jsp which would
display the results (data received from the session bean). I've tried
setting the value of the Search action property I'm trying to access from
Display.java to a constant value, but even then nothing is output in the
JSP. I'm the syntax you specified in your reply:
<s:property value="%{dataFromSessionBean}" />
The dataFromSessionBean has it's getter and setter methods defined.
My spontaneous question is if one has to define somewhere (such as in the
struts.xml file) that the action object be placed on some stack. Or do I
have to define the name of the Action also, when using the s:property tag?
I've tried various other ways, like <s:property
value="%{Search.dataFromSessionBean}" /> among others, but none works.
Thanks again.
