How do I get rid of TagExtraInfo JSTL warning in Eclipse?

Question

I'm working with JSTL in Eclipse, using the WTP. I have jstl and standard.jar in my WEB-INF/lib directory, and everything works. Eclipse is giving me this warning in my JSP:

The TagExtraInfo class for c:forEach (org.apache.taglibs.standard.tei.ForEachTEI) was not found on the build path.

I have JSTL included:

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

The warning is on a line that uses ac:forEach. How can I get rid of it? My project is targeting Tomcat v6.

Answer 1

将web.in目录中的standard.jar添加到构建路径jar。

Answer 2

Are the jars actually on the build path? If so, you might try closing and reopening the project. Otherwise that message is controllable from the Web/JSP Files/Validation preference page.

Answer 3

Eventually, I accidentally double-clicked the warning, and it took me to the source, which was editable. Then I fixed the problem myself.
