tomcat 5.0.28到tomcat5.5.26发生的JSP不能编译问题

[numbwood]

各位，问个问题，我应用从tomcat 5.0 -> tomcat 5.5之后，一直报
“org.apache.jasper.JasperException: Unable to compile class for JSP”错误，提示不能编译JSP，将jdk tools.jar包拷贝到tomcat lib下，还是同样问题，郁闷得要命，在tomcat 5.0下一切正常，何故？


错误描述：
org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 37 in the generated java file
The return type is incompatible with JspSourceDependent.getDependants()

下面是JSP转servlet 第37行代码
private static java.util.List _jspx_dependants;

public Object getDependants() { //第37行
return _jspx_dependants;
}

This problem is sometimes caused by an older version of the JspSourceDependent class being in one of your class loaders. In my case, GWT (google widget toolkit) had this class so that it could install a tomcat server, and it was causing this problem. If you are using an IDE, try looking for the class JspSourceDependent and see if it shows up in any of your jars. If it does, either edit the contents of the jar to take it out, or take the jar out of your WEB-INF/lib directory (or manifest files if you are using a classpath ref)

感谢M_song的指导，当我删除掉：jsper-runtime.jar之后，一切正常
