神秘的Eclipse JSP验证错误

本文介绍了神秘的Eclipse JSP验证错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

Eclipse（Helios）偶尔将有效的JSP内容标记为有错误。当我使用< c：if>标签。例如，在具有这个内容的JSP中：

 <％@ taglib prefix = curi =http://java.sun.com/jsp/jstl/core％> 
< html> 
< body> 
 
< c：if test =$ {1 == 1}> 
 something 
< / c：if> 
 
< / body> 
< / html>

我编译后的问题选项卡中显示以下错误：

不兼容的操作数类型String和
int行1

javax.servlet.jsp.JspException不能
被解析为类型行1

javax.servlet.jsp.PageContext不能
解析为类型行1

代码运行正常。 JSP的验证是否有问题，我缺少一些明显的东西，或者这表示某些东西没有正确设置。

解决方案

基于这些意见，我最终关闭了部分JSP验证，修正了这一点。

转到Project->属性 - >验证。

单击配置工作区设置...。

取消选择JSP语法验证器的选项。您需要取消选择手册和构建

我希望我错过了一些东西，有一种方法可以解决这个问题，但我有承认JSP验证是垃圾。

Eclipse (Helios) occasionally marks valid looking JSP content as having errors. It seems like it often breaks when I use the <c:if> tag. For example, in a JSP with just this content:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>

<c:if test="${1 == 1}">
something
</c:if>

</body>
</html>

The following errors show in the "Problems" tab after I compile:

Incompatible operand types String andint line 1
javax.servlet.jsp.JspException cannotbe resolved to a type line 1
javax.servlet.jsp.PageContext cannotbe resolved to a type line 1

The code runs fine. Does the validation for JSPs have issues, am I missing something obvious, or does this indicate something isn't set up correctly.

解决方案

Based on the comments, I ended up turning off part of the JSP validation, which fixed this.

Go to "Project->Properties->Validation".
Click "Configure Workspace Settings...".
Unselect options for JSP Syntax Validator. You need to uncheck both manual and build

I was hoping I was missing something and there was a way to fix this, but I have to concede that the JSP validation is junk.
