Hi all,
I was wondering how I could possibly solve this: I have an action in which
I construct quite a complex data structure. From that data structure I display
some tables and create some charts. Now, I have got this one big-ass java
class - extending ActionSupport, in which I do all the stuff - create data and
have functions for painting charts in temporary files. In JSP I do the obvious:
<s:iterator ...>
...... paint table
</s:iterator>
then the graphs:
<s:iterator value="%{getCharts(top)}">
<img
src="<%=request.getContextPath()%>/servlet/DisplayChart?filename=<s:property
/>" border=0">
</s:iterator>
where getCharts(top) is a function that constructs the charts and saves it in
files
and returns a list of filenames, and servlet/DisplayChart simply converts the
filename to full path and filename.
Now, the thing is, I would like to separate the code for painting the charts in
a different
file, and do something like this:
<s:iterator value="%{getChartsData(top)}">
<s:action namespace="charts" name="ErrorStat"
executeResult="true"/>
<%-- ^^^^^^^^^^^^^^^^^^^^^^^^^^^ --%>
</s:iterator>
But I need to pass current "top" to the action (or set a property in this
action) but I
have no idea how. I gather that I should be able to get to the "top" in my java
class
but it seems to be quite far fetched. I would rather set a property in this
action.
I have tried playing with <s:property, <s:push, <s:param without any success.
Am I missing something or is my idea totally wrong?
Thanks a million,
Petr Blahoš
