    Thanks Kuba.

    I had taken cue from his example to implement the chart. But the problem was I got
    500 Internal Server Error
    avax.servlet.jsp.JspException: data attribute evaluates to null
    at oracle.jbo.html.jsp.graph.GraphTag.doStartTag(GraphTag.java:212)
    at graphs.Graph_jspx._jspService(_Graph_jspx.java:67)
    [graphs/Graph.jspx]

    when including the ChartReport page in another page. Then I found that I had to redefine the page definition components of the Iterator and Graph from the ChartReport's page definition into the main page's Page Definition, where I am including the graph page.

    Now I have a solution for that - but got some other questions on twaeking the Graph...
    :)
    Will post soon. Thanks again.

    why don't you just add it into the page like the first person said:

    <f:verbatim>
    <graph:Graph data="${bindings.GraphViewRO1}"
    imageHeight="150"
    imageWidth="300"/>
    </f:verbatim>

    don't forget to add:

    xmlns:graph="/webapp/graph.tld"

    at the top and a servlet mapping in web.xml:

    GraphGeneratorServlet + /folderofyourjspx/GraphGeneratorServlet

    hi saranova,
    i used 88th example at http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
    to draw a graph on a adf faces page, (i dont use two pages, one page as in example)
    and i still get
    javax.servlet.jsp.JspException: data attribute evaluates to null
         at oracle.jbo.html.jsp.graph.GraphTag.doStartTag(GraphTag.java:212)

    error when i run the page.

    Could you please post your solution?

    thanks...
