项目启动后发生org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: o

起服务的时候出现：

HTTP Status 500 - /WEB-INF/views/login/login.jsp(2,62) Unable to read TLD “META-INF/c.tld” from JAR file “file:/D:/Program%20Files%20(x86)/workspace-muscoll_lsbwg/muscoll_lsbwg/WebContent/WEB-INF/lib/jstl-1.2.jar”: org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV



的错。

原因：项目中少了jsp-api.jar,servlet-api.jar

解决方案：直接把jar包贴进项目然后add to buildpath还不行，得在buildpath里直接找到jar包引入才可以
