创建SAX解析器时出错

Question

我正在使用JasperReports，当我尝试生成由我的tomcat服务器托管的html页面时，我遇到了异常。

该行：

JasperReport jasperReport = JasperCompileManager.compileReport(
"C:/Documents and Settings/axc1888/workspace/OATS/WebContent/status.jrxml");

以异常结束：

我认为它与服务器路径有关...

提前致谢。

你添加了一个重复的xml api（.jar），

删除所有关于jar的xml。

我有这个问题，我只是删除所有的罐子，然后只添加了neccessory jar ..
