如何在websphere中使用球衣来部署JAX-RS应用程序8.5

Question

当我在websphere 7.0中部署我的app.war时。平静的Web服务已成功初始化。
但我升级到websphere 8.5后。它无法部署宁静的Web服务类。
下面是我的app.war的运动衫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> 

下面是WebSphere错误日志时，启动应用程序：

通过谷歌搜索后，有人说，这可能是的Webshpere服务器已经包含了asm。所以我从我的app.war WEB-INF/lib中删除了asm.jar。但它仍然有错误。

Answer 1

除了@Surge的建议。
您是否尝试创建共享库，并将您的asm-all.jar jersery.jar放入您的库中并将共享库指定给您的应用程序。

Answer 2

你不应该从我们的WEB-INF/lib中删除你的asm.jar。相反，您应该指示您的websphere 8.5在WEB-INF/lib中使用asm.jar，而不是由Websphere安装提供的asm.jar。看看这个链接：Configure Web Module Classloader。您应该选择首先使用本地类加载器加载的类。

看起来这是在WebSphere 8.5 PM63479; 8.5: earexpander throws java.lang.incompatibleclasschangeerror的错误。请下载PM63479以查看它是否解决了您的问题。
