1.linkage Error

Java.lang.LinkageError: loader constraint violation: when resolving interface method异常

javax.servlet.ServletException: java.lang.LinkageError: loader constraint violation:when resolving interface method "javax.servlet.jsp

严重: Servlet.service() for servlet jsp threw exception

解决办法：

就是你不能在项目的lib目录中再包含服务器类提供过jar 比如jsp-api.jar, el-api.jar, servlet-api.jar, 等等

javax.faces.FacesException: java.lang.LinkageError: loader constraints violated when linking javax/el/ExpressionFactory class  
    org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:425)

    org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:108)

    org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:141)  
    org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:281)

错误的原因是tomcat/lib下的el-api.jar与项目WEB-INF/lib目录下的el-api.jar冲突。

把项目目录下的el-api.jar删除即可。
