Question

我编译了我的xsd doc并开始为我的包装器编写junit测试。

当我打电话给marshal时，我得到下面的堆栈跟踪。没有找到日食课，我感到很惊讶。（org.eclipse.persistence.jaxb.JAXBContextFactory）

我的课程中缺少什么？或者还有其他我想念的东西？

我正在运行eclipse indigo 3.7.2。

我的类路径包括以下jar： jaxb-api.jar，jaxb-impl.jar，jaxb-xjc.jar，jaxb1impl.jar，jsr173_1.0_api.jar，

我的编译器设置为java 6 compatability。

更新：手动解决方法 缺少的jar文件是jaxb-impl.jar它在我的类路径中包含在ear项目中的jar中。如果我在默认类路径之前的类路径中添加jaxb-impl.jar。它运行良好。

在同一个工作区的其他项目中，我没有这个问题。

您可能需要以下依赖项，如果您使用的是Maven，请参考以下依赖项：

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>org.eclipse.persistence.moxy</artifactId>
        <version>2.6.8</version>
    </dependency>
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.2.11</version>
    </dependency>
