containers - 无法创建 WebSphere 8 的可嵌入 EJB 容器 - NoClassDefFoundError HpelHelper

Question

我正在使用 WebSphere 8 的可嵌入 EJB 容器为我的 EJB 和 JUnit4 编写一些单元测试。我的 IDE 是 RAD 8。

这是我的简单测试代码片段：

 

    Map properties = new HashMap();
    properties.put(EJBContainer.PROVIDER,
                "com.ibm.websphere.ejbcontainer.EmbeddableContainerProvider");
    EJBContainer ec = EJBContainer.createEJBContainer(properties);

我得到一个 NoClassDefFoundError：

我在任何地方都找不到带有 com/ibm/ejs/ras/hpel/HpelHelper 类的 jar。

Answer 1

WebSphere 可嵌入 EJB 容器中包含的 RAS 不使用 HPEL。此错误消息暗示您的类路径中的某些 JAR 正在使用不同的 RAS。您应该删除所有 WebSphere JAR，除了C:\Program Files\IBM\WebSphere\AppServer\runtimes\com.ibm.ws.ejb.embeddableContainer_8.0.0.‌​jar.

Answer 2

我能够摆脱这个问题是取消选中项目方面的运行时选择。

我在 JUint 中的配置如下

地图属性 = new HashMap(); properties.put(EJBContainer.PROVIDER, "com.ibm.websphere.ejbcontainer.EmbeddableContainerProvider"); 文件 jar = new File("./target/test_ejb.jar"); properties.put(EJBContainer.MODULES, jar); //可嵌入容器中配置的数据库属性 properties.put("com.ibm.websphere.embeddable.configFileName", "./target/test-classes/embeddable.properties"); EJBContainer ec = EJBContainer.createEJBContainer(properties);

Answer 3

连接到 FileNet P8 时，我也遇到了这个错误。我需要：

• com.ibm.ws.ejb.embeddableContainer_8.5.0.jar
• com.ibm.ws.ejb.thinclient_8.5.0.jar
• ibmorb.jar
• com.ibm.ws.emf.jar
• j2ee.jar
• 杰斯.jar
