高分求解：weblogic下运行不了jsp的原因，同样的程序放在tomcat下就能运行，困惑中......

[kaka2345]

我运行的程序是eWebEditor在线文本编辑器jsp版的，放在tomcat下运行一点问题都没有，在weblogic下会出现这样的错误提示：

java.lang.ClassNotFoundException: org.apache.jasper.servlet.JspServlet
你没把相应的jar导进去啊。去\jakarta-tomcat***\common\lib下找到需要的包（你用winrar什么的打开，看哪个有org\apache\jasper\servlet\的目录结构就是），加入到CLASSPATH里

[kaka2345]

十分感谢 leonwu1981_2(精童欲女)
可是又出现一下错误

java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

保证commons-logging.jar文件在WEB-INF/LIB路径下

[kaka2345]

可是tomcat/common/lib下没有commons-logging.jar和servlet.jar啊

[kaka2345]

把*.jar文件加到classpath里是不是和放到 程序根目录/WEB-INF/lib目录下是一样一样一样的？

[kaka2345]

我把commons-logging.jar放到WEB-INF/lib下还是显示这个错误
jsp调试难道就这么难吗

[vistaflorabflunt]

到apache网站上找到commons-logging.jar等包，放进去就可以
放到classpath路径

[kaka2345]

vistaflorabflunt(Jerry),我按照你说的方法做了，可是又出现异常了
