关于Filter的问题
想了解一下Filter，就写了这样一个小程序
web.xml这样的
<filter>
<filter-name>testFilter</filter-name>
<filter-class>com.hh.test.TestFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>testFilter</filter-name>
<url-pattern>/myspace/test/testFilter.jsp</url-pattern>
</filter-mapping>
TestFilter.java：
public class TestFilter implements Filter
{
public void destroy()
{
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2)
throws IOException, ServletException
{
System.out.println("testFilter");
arg2.doFilter(arg0, arg1);
return;
}
public void init(FilterConfig arg0)
throws ServletException
{
// TODO Auto-generated method stub
}
}
访问了一下/myspace/test/testFilter.jsp
就报错误了。。。
严重: Servlet.service() for servlet jsp threw exception

[解决办法]
没用的jar都删了吧。
[解决办法]
你应该查看下你的jsp页面，应该是那个标签写错了
