Calling a static method with a struts variable

[Frank Bueckert]

Not exactly sure how to go about this. I'm using the JFreeChart jar file to generate a dynamic image based on the data I'm using. That's all fine and dandy.
My problem is accessing a variable I'm defining in the action, and using it in a scriptlet to write an imagemap straight into the JSP.

<bean :mrgreen: efine id="info" type="org.jfree.chart.ChartRenderingInfo" scope="page"><bean:write name="graphForm" property="info"/></bean :mrgreen: efine>

This defines the variable for the JSP. That part works fine. However, when I try to use it in a scriptlet, it turns up as null.

ChartUtilities.writeImageMap(pw, "imap", (org.jfree.chart.ChartRenderingInfo) pageContext.getAttribute("info") , false);

I've tried using "info", "(org.jfree.chart.ChartRenderingInfo) info", and any other variations I can come up with. I know I'm doing something wrong, but I have no idea what.

You can't nest one Struts tag inside another.

change your <bean:define>tag to:

<bean:define id="info" type="org.jfree.chart.ChartRenderingInfo" scope="page" name="graphForm" property="info"/>

If you do this, your scriptlet should work.

You could also try getting the info bean directly from the ActionForm, as in:

org.jfree.chart.ChartRenderingInfo info = ((com.mycompany.GraphForm)request.getAttribute("graphForm")).getInfo();
ChartUtilities.writeImageMap(pw, "imap", info, false);
