我用weblogic部署的项目，用到<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>标签库，但提示：
weblogic.servlet.jsp.CompilationException: Failed to compile JSP /el.jsp
el.jsp:2:4: No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

其中点击：JavelinxJSPStub.java:226、JavelinxJSPStub.java:162、JspStub.java:246、JspStub.java:191、ServletStubImpl.java:235。提示：Source not found for weblogic.servlet.jsp.*
------解决方案--------------------
缺少jstl的包jstl.jar以及一系列的tld文件吧。。。仔细检查一下。。
