Websphere 中的 JAXWS

【问题标题】：JAXWS in WebsphereWebsphere 中的 JAXWS
【发布时间】：2012-03-08 20:17:56
【问题描述】：

我在 Netbeans 中编写了一个简单的 Web 服务，如下所示。

@WebService()
public class CRSEncryptString {

/**
 * Web service operation
 */
@WebMethod(operationName = "encryptString")
public String encryptString(@WebParam(name = "plainText")
String plainText) {
    System.out.println("************* ");
    String cipher = plainText;
    System.out.println("***************************");
    return cipher;
}

}

添加的 jar 与 JAX-WS 相关，例如： activation.jar、FastInfoset.jar、http.jar、jaxb jar、jaxws jar、saaj jar 等

它在 Tomcat 和 Weblogic 中运行良好。

但是，在Websphere 6.1 中运行时出现错误。

以下是服务器日志：

请进一步建议我。

    【解决方案1】：

    我通过管理控制台更改 Websphere 的类加载器策略解决了这个问题，即从 Parent_first 到 Parent_last 策略....

    【讨论】：

      【解决方案2】：

      一般来说，如果您不使用 WebSphere 自己的实现，我认为您将难以在 WebSphere 下使用 JAX-WS。因此，您不希望部署任何额外的 jar，而是使用 WebSphere 7 中已经存在的那些。

      【讨论】：

        【解决方案3】：

        如果您使用的是 RAD，您应该将 Websphere Application Server 运行时添加到您的项目构建路径中，而不是添加外部 jar。

        【讨论】：

        • 请你建议我在运行时添加的过程......它适合我的问题......
        • 我手头没有 RAD，但它是这样的：右键单击您的项目 -> 构建路径-> 库，然后将 IBM WAS Runtime 添加到您的项目中。
        【解决方案4】：

        更改 Websphere 中的类加载器顺序是有风险的，因为您正在加载 Websphere 可能不支持的自定义实现，并且您可能会遇到诸如 LinkageErrors 和 ClassCastException 等运行时错误，因为不同的实现共存于同一个 Java 进程中。最好的方法是使用 IBM 支持的 Jax-WS 编程模型。 或者，您可以通过禁用 IBM 的

        来使用自定义 Web 服务引擎
