当我在 websphere 7.0 中部署我的 app.war 时。RESTful Web 服务已成功初始化。
但是在我升级到 websphere 8.5 之后。它未能部署 RESTful Web 服务类。
下面是我 app.war 的球衣 pom.xml。

    <!-- restful web service -->

        <artifactId>jersey-json</artifactId>
        <version>1.17</version>
        <scope>compile</scope>
    </dependency>

下面是我的 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>

以下是启动应用程序时的 websphere 错误日志：

After search by google , some one says it may be webshpere server already contain the asm. So I delete the asm.jar from my app.war WEB-INF/lib. But it still has the error.

You should not delete your asm.jar from our WEB-INF/lib. On the contrary, you should instruct your websphere 8.5 to use the asm.jar in the WEB-INF/lib instead the asm.jar provided by the Websphere installation. Check out this link: Configure Web Module Classloader. You should choose Classes loaded with local class loader first.

Edit based on comments:

Looks like this is a bug in Websphere 8.5 PM63479; 8.5: earexpander throws java.lang.incompatibleclasschangeerror. Please download PM63479 to see if it fixes your issue.

Except @Surge advice.
Have you try to create a shared library, and put your asm-all.jar jersery.jar into your library.And specify the shared library to your application.
