Question

我正在尝试使用RestEasy运行简单的restful服务。以下是我的设置。

Tomcat7 Eclipse＆amp; Maven的我Maven安装war文件并将其复制到webapps文件夹。

部署war文件时，catalina.out文件会显示此信息并且未部署应用程序。

    Mar 24, 2013 9:44:38 PM org.apache.catalina.loader.WebappClassLoader validateJarFile
INFO: validateJarFile(/usr/share/tomcat7/webapps/buzzcore-1.0/WEB-INF/lib/el-api-1.0.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/el/Expression.class
Mar 24, 2013 9:44:40 PM org.apache.catalina.core.ContainerBase addChildInternal
SEVERE: ContainerBase.addChild: start: 
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/buzzcore-1.0]]

我不确定导致问题的原因。以下是我的pom.xml和web.xml。

这是一个OpenShift应用程序，因此是openshift条目。我已将RestEasy中的lib复制到src \ main \ webapp \ WEB-INF \ lib。

Answer 1

尝试将以下内容添加到您的pom文件并再次打包：

        <dependency>
            <groupId>javax.el</groupId>
            <artifactId>el-api</artifactId>
            <scope>provided</scope>
            <version>1.0</version>
        </dependency>

Answer 2

当我在Java 1.6上设置项目时，遇到了这个问题。当我将Java版本更改为1.8并在tomcat中部署时，我遇到了同样的问题。我没有花太多时间在上面。但是恢复到1.6版可以解决此问题。

el-api-1.0.jar - jar not loaded - 违规类：javax / el / Expression.class
