[birt-charting-dev] chart don´t render in html mode report

["Michela Limaco" <michela@xxxxxxxxxxxxx>]

Good night folks,

I met BIRT recently, made a few reports and became satisfied with the 
results.
Now, i need to create a report with a chart, but i´m having some problems.
The static image generated by chart, indicates a path on my pc...and don´t 
render in report (html mode).
I´m using a WebReport to generate the report.
Bellow is the BirtEngine and WebReport:

         loadEngineProps(); 
    } 

    public static synchronized IReportEngine getBirtEngine(ServletContext 
sc) {

         {
