【问题】Unable to read TLD "META-INF/c.tld"错误（JSP不能成功显示时的报错）

JSP页面显示不了，报错如下:

org.apache.jasper.JasperException: Unable to read TLD "META-INF/c.tld" from JAR file "file:/C:/Program Files/Apache Software Foundation/Tomcat 5.5/webapps/JSPBook/WEB-INF/lib/standard.jar": org.apache.jasper.JasperException: Failed to load or instantiate
TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV

org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:510)

org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:375)

org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)

javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

出错原因:

WEB-INF/lib下的   servlet-api.jar     jsp-api.jar    和tomcat自己的   servlet-api.jar    jsp-api.jar    冲突了.

解决方法:

去掉WEB-INF/lib下的 servlet-api.jar  jsp-api.jar  即可.
