JSP中的Eclipse Keppler Java 1.7错误

Question

I work with Eclipse Keppler and Java 1.7.

I have the following jsp

<c:choose> 
<c:when test='${attributeName.name.equals("Owner")}'> 
/*    <c:when test="${attributeName.name == 'Owner'}">  */
$(td).append(list[i].owner);
</c:when>
<c:otherwise> 
$(td).append(getAttributeValue(list[i].attributes, '${attributeName.id}', '${attributeName.name}'));
</c:otherwise>
</c:choose>

In the Keppler editor I have the following error

I configured the values:

Is it something wrong in this configuration?

Answer 1

您必须导入JSTL jar并添加

`<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>` at top of jsp page

Answer 2

I think this is an Eclipse bug. It looks similar to the bug .

You may have to use new version of Eclipse.

Answer 3

I think it is a bug , anyway doing like below will prevent even different kind of errors in jsp

Project properties --> Validation --> disable all validators in the grid
