我使用Eclipse Indigo、Jboss、Seam和RichFaces

谢谢!


共 (2) 个答案

  1. # 1 楼答案

    您需要检查部署应用程序的部署目录。检查您的类是否存在于WEB-INF/classes中，或者至少存在于WEB-INF/lib文件夹中的任何jar中。 如果使用eclipse WTP插件部署应用程序，则必须检查应用程序文件是否正确部署。有时运行时无法与项目输出文件正确同步

  2. # 2 楼答案

    出现此错误是因为类路径上没有com.akson.encuesta.session.helper.LogoutListener的类文件。检查项目中的.jar以获取此文件，如果没有，则添加它

    如果这是项目中您自己的类，请尝试在Eclipse中重新编译该项目
