Hi,

 

I am trying to export Fusion charts server side, the export is initiated through javascript. Its ASP.net application

 

I am using Fusion charts version : FusionCharts v3.2.1 (Released on 6th October 2010)

 

The problem i am facing is... the export happens properly if i run it locally in visual studio through F5...

 

But when i deploy it in IIS and try to browse to the page and export it i get the error saying it was not able to reach the export handler.

 

Please advise on resolving this issue :(

 

The XML is as below

 


<chart exportEnabled='1' exportAction='Save' exportAtClient='0' exportHandler='http://localhost:843/Export_Handler/FCExporter.aspx'
caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' showValues='0' formatNumberScale='0' showBorder='1' >
<set label='Jan' value='462' />
<set label='Feb' value='857' />
<set label='Mar' value='671' />
<set label='Apr' value='494' />
<set label='May' value='761' />
<set label='Jun' value='960' />
<set label='Jul' value='629' />
<set label='Aug' value='622' />
<set label='Sep' value='376' />
<set label='Oct' value='494' />
<set label='Nov' value='761' />
<set label='Dec' value='960' />
</chart>

 

The path : http://localhost:843...FCExporter.aspx is valid when i browse to this from IIS i get the below

 


DOMId=
height=0
width=0
fileName=
statusMessage=Insufficient  data.
statusCode=0

 

 

please find the attached screen shots and the aspx code files

Have you tried creating a Virtual directory within IIS for where the exportHandler is located and using that path in the exportHandler setting? You might also want to make sure the correct permissions are granted on the directory for the ExportHandler to IIS's built-in users.

 

That's my 2-cents' worth :^)
