侠客们！！！ 在resin2.1.8下运行jsp的问题？

[qinxiaolin]

错的问题是：
500 Servlet Exception
error: Invalid class file format: D:\JBuilder8\jdk1.4\jre\lib\rt.jar(java/util/ArrayList.class),
wrong version: 48, expected 45
/_jsp/upload.jsp:55: Class java.util.ArrayList not found in type declaration.
private java.util.ArrayList _caucho_depends = new java.util.ArrayList();
^
/_jsp/upload.jsp:55: Class java.util.ArrayList not found in type declaration.
private java.util.ArrayList _caucho_depends = new java.util.ArrayList();
^
3 errors

在classpath中设置一下rt.jar包的路径
如果设置后还出错

建议重新下载，估计rt.jar包已被损坏
建议下1.3版本的试试

重新安装一遍jbuilder8试试看
