java.lang.NoClassDefFoundError: org.apache.jasper.el.ELContextImpl (初始化失败)

我们已经升级到Websphere 9以及Camel 2.17、Java8和Spring4。
在这个包里，我们有下面的jars
camel-jms-2.17.0.jar, camel-juel-2.17.0.jar, camel-spring-2.17.0.jar在was文件夹中，我们有下面的jars，包含ElContextImpl。
javax.j2ee.el.jar, com.ibm.ws.webcontainer.jar在访问url时获取以下异常。不确定它造成此错误的结果是什么，无论是版本错配、冲突还是类路径问题。

这个问题与jar的camel.This版本为JSP2.1所引用的juel有关；因此，它不支持用于WAS9.0.0.2的El3.0。所以我已经删除了这个罐子，因为没有更高版本的这个jar，并且用juel-impl-2.2.7.jar代替了这个。
现在起作用了。
