Question

我在Grails项目中使用Jasper插件。在NetBeans中运行时，该应用程序运行良好。但是在部署到Tomcat之后，除报告之外的一切都运行良好。当我试图运行报告（jasper）时，地狱爆发了。它给出了“未找到类错误。

我使用的版本是 Grails 2.2.4 Jasper插件1.7.0 Tomcat 7.0.34

有没有人遇到过这个问题？任何帮助或指示都将非常感激。

Answer 1

似乎在服务器中你缺少了Joda Time库。

下载joda-time.jar文件并将其放在$ TOMCAT_HOME / lib /目录中。然后重新启动Tomcat，错误应该消失。

在Tomcat服务器上运行Grails-Jasper报告时出现类未找到错误
