Class Cast Exception error

2003-05-24 13:37

Could anyone help with the following exception that I am getting. I can view the report design just fine by hard coding the .xml file (of the report) in the JasperDesignViewer's main method. When I do the same in the JasperViewer's main method I get a Class Cast Exception. It leads back to Digester. Any help would be appreciated. Thanks in advance.
