html reports from web app

2002-10-30 10:48

Hi,

 

I have a web application that produces pdf reports.

I'm improving it to allow also html reports. however, I can only export html reports to a file. is there a way to serve them directly without having to use files ?

 

is anyone doing this ?

 

thanks

Hi,

 

I'm afraid it is not possible.

At least not with the supplied HTML exporter.

 

If you have images in the report, there's no way

to send them along with the HTML code (in-line).

Even if you don't have images, this built-in HTML

exporter uses a 1 pixel transparent GIF to align the

elements.

 

So, the result of the HTML export process is not

a single file, that you could send directly over the

network, or something.

It is always a file, accompanied by a directory

containing images.

 

Thank you,

Teodor

thanks for your answer.

 

I am aware of the way it works. Still, since the main use of HTML reports (I think) is to serve them online, it would be nice to be able to do it without involving the filesystem.

 

I had an ideas :

 

If the jasper HTML exporter was able to return the HTML and the images for example in an hashtable, they could be stored in the session and delivered to the client.

 

What do you think of this ?

 

thanks

Hi,

 

Just wanted to say that this is already implemented

in recent versions of JasperReports.

This is how the "webapp" sample works.

 

Thank you,

Teodor

Me, I'm use JFreeChart.

 

You do your chart in scriptlet.

 

You can see an example in demo/samples/chart in the folder of JasperReport.
