I have used the swingx library provided by Synthetica. Added Addon jar also.

Please help me out.

Answer 1

Solution for my problem I got from jyloo.com is :

Reply from jyloo.com :

Generally SwingX support is provided by SyntheticaAddons - so you additionally need SyntheticaAddons. We also recommend to use our DateComboBox component instead of JXDatePicker.

so I added the syntheticaAddons.jar and syntheticaAluOxideAddon.jar to my classpath and used the de.javasoft.swing.DateComboBox.

I worked like charm.

Thanks to all the Supporters from stackoverflow.com and jyloo.com support team.

Answer 2

I have had this exception as well, but it some years back already. I remember it because it seems that Synthentica is enforcing the use of its SwingX extention when you only have a license for Synthetica core, and I was "not amused" by that. Turns out that this is not the case (because I'm using Synthetica core + SwingX now), but my memory fails me in how I got rid of that exception. Searchinf through the source code does not help either, so maybe an emailto Jyloo is in order.
