我有一个在Tomcat 6上完全正常运行的应用程序。我现在已将此应用程序移至Tomcat 7并且JSP正在抛出编译异常

我看了一下jasper为两个tomcat版本创建的java文件，我发现了一个重大的变化。例如，对应于行号中的错误。 22，tomcat 6的java文件中的getDependants（）方法具有以下签名：
public Object getDependants() {
return _jspx_dependants;
}
而在Tomcat 7的情况下，这是
public java.util.Map<java.lang.String,java.lang.Long> getDependants() {
return _jspx_dependants;
}
如果有人可以帮助我确定需要纠正的问题以解决此问题，那将会很棒

终于找到了冲突的jar。它是org.osgi.foundation-1.2.0.jar。但是，我正在使用的另一个依赖项需要此jar，因此需要找到解决此问题的方法。
答案 1 :(得分：0)
此错误通常是由在Tomcat 6上编译JSP然后尝试在Tomcat 7上运行它们引起的。
如果要预编译JSP，请确保用于预编译的所有Tomcat库都与Tomcat的运行版本完全相同。
如果您正在动态编译JSP，请确保在从Tomcat 6切换到Tomcat 7时清空工作目录。
还要确保您的Tomact 7安装不包含Tomcat 6安装中的任何杂散库，并且您的Web应用程序中不包含任何Tomcat JAR。
答案 2 :(得分：0)
将此行添加到context.xml应解决此问题。
