beforeDetailEval: setVariableValue for image?

2003-04-08 09:55

Can I use setVariableValue to set an image for the beforeDetailEval event?

 

I would like to use a scriplet to set the image variable in my detail to different colors depending on the value of the data.

I'm passing my scrptlet as follows:

 

MyScriptlet scriptlet = new MyScriptlet();

parameters.put("REPORT_SCRIPTLET", scriptlet);

 

Do I need to do anything in my report to have the afterDetailEval listener get triggered.

 

I have a variable which I use in the detail of my report:

<variable name="myImage" class="java.awt.Image" calculation="System" />

 

<imageExpression class="java.awt.Image"><![CDATA[$V{myImage}]]></imageExpression></image>

Hi,

 

Unfortunately, you cannot pass the scriptlet object

as a parameter, like in the code you posted.

This object is instantiated always by the engine

from the specified "scriptletClass" attribute.

 

This is why it does not work for you.

 

I have to dig into this issue to see if we can allow

passing the scriptlet object like this in future versions.

 

Thank you,

Teodor

I continue to get the following error:

 

dori.jasper.engine.JRException: Error creating scriptlet class instance : MyScriptlet

 

I've also tried the following, but it seems the class is not found. Do you know how this should be specified?

 

com.transgenomic.navigator.reports.MyScriptlet

Hi,

 

We need the entire class name like in your

last line.

Make sure the scriptlet class is in the classpath

when you fill your reports and that it has an empty

constructor.

 

I hope this helps.
