jsp的<% %>中使用 像ArrayList<String> al = ...的时候会报'<'是非法字符？？
jsp的 <% %> 中使用 像ArrayList <String> al = ...的时候会报 ' < '是非法字符？？
比如 <%@ page language= "java " import= "java.util.* " pageEncoding= "UTF-8 "%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+ ":// "+request.getServerName()+ ": "+request.getServerPort()+path+ "/ ";
%>

參考一下

[解决办法]
泛型是1.5以后的东西.
[解决办法]
针对这个问题我刚才试了一下，
<%
ArrayList <String> al = new ArrayList <String> ();
%>
在jsp中这样写没有问题~~~
你看下的你那个项目的jdk是不是1.5以上的，因为泛型只在1.5以后才有
或许你再看看代码的其它地方，可能是其它地方的错~
