Error when defining backcolor for Rectange element

[explorer]

Hello,

If backcolor is defined for a rectange element in a report and then when the report is run, it throws the exception:

Class not found when loading object from file

In the stack trace, it shows the cause of the problem as:

Caused by: java.lang.ClassNotFoundException: org.netbeans.beaninfo.editors.ColorEditor$SuperColor

I understand that some required jar that includes the above-mentioned netbeans class is not added to the report's classpath, and that's why the error. But, how can I figure out which jar to add to get rid of the error. There are so many jars in the "lib" directory of Jasper Reports, and I can't seem to find any documentation explaining the purpose of each jar.

I would be thankful if someone could suggest the name of the jar to add to resolve the problem.

Thanks.

On Windows:

 

jar -tvf \ireport\platform9\modules\org-netbeans-core.jar > c.txt

notepad c.txt

 

Search for SuperColor. You'll find it.

 

Use GrepWin on Windows to search the contents of lots of files.

use basic  color for background ..the above error belong to super color , if you are using super color and got above error and googling will  not get you any solution . but in some post they suggested some jar but did not work for me. simple solution use basic color for backcolor-rectange-element
