如何在websphere 8.5中使用jersey部署JAX-RS应用程序

Question

当我在websphere 7.0中部署app.war时。restful web服务初始化成功。处理步骤
但是在我升级到websphere 8.5之后。未能部署restful web服务类。
下面是我的app.war的pom.xml。

    <!-- restful web service -->
    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>jsr311-api</artifactId>
        <version>1.1.1</version>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>asm</groupId>
        <artifactId>asm-all</artifactId>
        <version>3.2</version>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-core</artifactId>
        <version>1.17</version>
        <scope>compile</scope>
    </dependency>
     <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-servlet</artifactId>
        <version>1.17</version>
       <scope>compile</scope>
    </dependency>  
     <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.17</version>
       <scope>compile</scope>
    </dependency>  
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.17</version>
        <scope>compile</scope>
    </dependency>

下面是my web.xml

  <servlet>
    <servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
      <param-name>com.sun.jersey.config.property.packages</param-name>
      <param-value>com.tag.services.testrsws</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rs/*</url-pattern>
  </servlet-mapping>
</web-app> 

下面是启动应用程序时的websphere错误日志:

经过google搜索，有人说可能是websphere服务器已经包含了asm。所以我从app.war WEB-INF/lib中删除了asm.jar。但是它仍然有错误

Answer 1

@Surge advice除外。
您是否尝试创建一个共享库，并将asm-all.jar jerserry .jar放入库中?并为应用程序指定共享库。

Answer 2

您不应该从WEB-INF/lib中删除您的asm.jar。相反，您应该指示websphere 8.5使用WEB-INF/lib中的asm.jar，而不是websphere安装提供的asm.jar。查看这个链接:配置Web模块类加载器。您应该选择首先使用本地类加载器加载的类。

看起来这是Websphere 8.5 PM63479中的一个bug;eareexpander抛出java.lang.incompatibleclasschangeerror。请下载PM63479，看看是否能解决您的问题。
