[Could not initialize class net.sf.jasperreports.engine.util.JRStyledTextParser]

Have you fixed this issue. I am getting the same error on server. Please provide me the solution.

[Jasper Design Viewer and JasperViewer]

 I couldn't see the design view and print view from the following ant build file, but there is no error. I am able to create .jasper and .jrprint files. Please let me know if I missed anything.
