java.lang.NullPointerException at org.apache.taglibs.standard.tlv.JstlBaseTLV.validate(JstlBaseTLV.j

org.apache.taglibs.standard.tlv.JstlCoreTLV

Linux环境下,jdk6+tomcat7,

出现如下异常:Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV ,

jsp页面无法解析

发现原来的项目里有重复的包,

org.apache.jasper.glassfish-2.1.0.v201110031002.jar,

org.apache.taglibs.standard.glassfish-1.2.0.v201112081803.jar

删掉就好了。
