need help with webapp

2002-01-31 12:09

Hi,

I am trying to implement the sample app as a web app. I am following some of the advice in the

thread: http://sourceforge.net/forum/forum.php?thread_id=617668&forum_id=113529

 

I am getting this error:

dori.jasper.engine.JRException: Error loading image data : JasperReports.jpg

 

What can I do to make this work?

Has anyone else converted the sample app as a web app?

 

Help!

 

Thanks,

Michelle

Ok, in order to get past this error I removed the following section from the xml file:

 

<image scaleImage="RetainShape">

<reportElement x="5" y="5" width="165" height="40"/>

<graphicElement/>

<imageExpression>"JasperReports.jpg"</imageExpression>

</image>

 

 

Now, I run it and get this error displayed in the browser:

 

Error occured

The exception reported this message: Width (-1) and height (0) must be > 0

 

java.lang.IllegalArgumentException: Width (-1) and height (0) must be > 0

webapp problems

2002-02-01 12:15

I figured out this problem.

It was because of the duke image.

In the webapp environment the application doesn't know how to get various resources from within a webapp archive. Also, had problems with the pdf font comic.ttf. I removed all of these things and I get to the point where it returns data but it is not viewable as a pdf.

 

I will need to start building the reports application next week as a web app and it looks like this framework needs quite a bit of work to get it going in that environment. If I can get some help over the next few days, maybe I'll be able to do it...?

Hi,

 

If there are no more errors when generating the PDF content,

try browsing with Netscape because IE behaves weird sometimes.

 

Enhanced Web support has already been introduces and will be

available in the 0.2.3 version this week.

It includes support for working with streams and loading images

from CLASPATH and URLs.

 

Thanks,

Teodor
