i am looking for graphing tag for JSF. i found one on http://www.jenia.org/jsp/chart.jsf but it is not working. there is a .war file. it works. but if i change the application name, it doesn't. like webapp name is TestChart1.1 , if i change it to test then tomcat throws exception. there is guide name 'BarChart3Dguide'. i have followed the steps. But i couldn't succeed. tomcat throws exception. the exception is "can't parse configuration file :..../jenia4faces-chart_1.1.jar"
