Hello,

Sorry for the delay with this reply. I tried running the example as a new project in Eclipse. I didn't see the error you describe. The steps I took were:

1. download latest version of TeeChart for Java v2
2. Open Eclipse and create new client application
3. Link source to the 'Examples\SWT\Features\src' folder
4. Add external Jar library links to Eclipse's 'org.eclipse.draw2d_3.xx','org.eclipse.jface_3.xx' and 'org.eclipse.swt_3' jar files (xx version numbering will vary)
5. Add external Jar library link to 'TeeChart.SWT.jar'.
6. Build and run project and open/run 'Basic features' example page.

Please verify the steps taken.

Regards,
