Loading image from DB

2002-09-19 09:18

I am new to Jasper so please bear with me.

 

I need to retrieve an image (gif) from the DB and insert it into the report.

 

Ideally I would like to add it as a parameter at run time (map it to a variable name) so that the XML will just have a placeholder such as ${Logo}.

 

Is this possible? How?

 

Cheers

Hi,

 

The only thing you have to do is to declare a report field of type java.io.InputStream that will point to the table column that stores the GIF files.

 

Then, in the <imageExpression> tag you use this field directly like this:

 

<imageExpression class="java.io.InputStream">$F{MyImageField}</imageExpression>

 

I have tried it once and it worked. perfectly.

 

I hope this helps.
