iReport charts

[deepthynair]

hi all,

I am new to jasper reports and ireports.I am trying to generate charts using ireports from javabean datasource.I want to plot the chart between two values retrieved from the bean . charts demand the chart details value expression as numeric value.But I could not cast the values retrieved from bean to numeric values.It is showing class cast exception.

Can i convert a string field value to numeric value in the expression editor?

Pls help.

Hi All,

I have problem displaying two html reports in one page.

I have 2 jasper report graphs and in my html page
I have 2 iframes to display both graphs.

but the image of the graph seem to be the same for both reports, yet if I refresh iframe then I get the correct graph.

the problem seem to be that both get invoke using the same servlet at the same time.. so it's getting the same image for both graphs.
