pdf with images loaded via URL

2003-08-29 06:32

Hi All,

I have a problem trying to convert a report in pdf.

I've a table, on my DB, with a field containing an URL that points to an image (jpg) placed on a web server.

I can fill the report, and If I run the view task, everything is ok (I can see the images loaded). But when I try to convert the report with pdf task, I obtain this message:

 

pdf:

BUILD SUCCESSFUL

Total time: 6 seconds

 

This is the code of the report:

<image scaleImage="RetainShape">

<reportElement x="200" y="4" width="30" height="20"/>

<graphicElement pen="Thin"/>

<imageExpression>$F{DEFORGURL}</imageExpression>

</image>

 

where DEFORGURL is a field readed from a table with a query. It's a String field with value like:

http://aaaa.bbb.ccc/blabla/aaa.jpg

 

If I change the report xml, pointing <imageExpression> to a file on my local disk, the pdf task is ok.

 

I'm using JasperReports 0.4.6.

Could you help me?

 

TIA

Matteo

Maybe I guess the problem.

If I avoid to load (in the query) the field DEFORGURL with value = '' then it works!

So my question is: is it possible to determine at runtime (fill) the value of a field, so I can choose what to do?

 

For example, how can I write the construct:

<condition ? value if true : value if false>

inside the <imageExpression> tag?

 

Thanks

I believe this should work:

 

<imageExpression> new java.awt.Image((condition) ? value if true : value if false) </imageExpression>

Where you able to get images loaded successfully via URL. If so, could you explain how it was done?

 

Thanks
