Resteasy:java.lang.NoClassDefFoundError:javax / servlet / ServletContext

标签: java-ee jboss jboss7.x resteasy web.xml

我在web.xml中配置了Resteasy servlet和监听器

<servlet-mapping>
    <servlet-name>resteasy-servlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

<!-- Auto scan REST service -->
<context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>true</param-value>
</context-param>

<!-- this should be the same URL pattern as the servlet-mapping property -->
<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
</context-param>

<listener>
    <listener-class>
        org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
    </listener-class>
</listener>

<servlet>
    <servlet-name>resteasy-servlet</servlet-name>
    <servlet-class>
        org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
    </servlet-class>
</servlet>

当我尝试在JBoss-as-web-7.0.0.Final上部署EAR时,我收到错误:

  

org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap:   java.lang.NoClassDefFoundError:javax / servlet / ServletContext

我的EAR里面包含war和EJB jar,如果它有意义的话。

1 个答案:

答案 0 :(得分:1)

1)您需要在项目中使用servlet api依赖项,如下所示:

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.0.1</version>
  <scope>provided</scope>
</dependency>

OR

在类路径中添加javax.servlet-3.0.jar文件。

2)转到<JBOSS-HOME>/standalone/configuration/standalone.xml

找到元素 <subsystem xmlns="urn:jboss:domain:ee:1.0" />

并将其替换为

<subsystem xmlns="urn:jboss:domain:ee:1.0">
  <global-modules>
       <module name="javaee.api" slot="main"/> 
  </global-modules>
</subsystem>`

3)转到 JBoss\jboss-eap-6.1\modules\system\layers\base\javax\servlet\api\main

包括JAR jboss-servlet-api_3.0_spec-1.0.2.Final-redhat-1.jar

我建议您仅使用Jboss AS 7.1.1.Final版本而不是7.0.0 Final。
