我正在尝试在 websphere 8 上部署一个 ejb 3 的 bean。Bean 实现在 src/main/java 中，ejb-jar.xml 在 src/main/resources/META-INF 中。它被包装在一个罐子里，这个罐子包含在耳朵里，耳朵里还有其他带有 ejb 2 的 ejb 罐子。所以耳朵包含 ejb 2 和 ejb 3 罐子。在网络圈中部署此耳朵期间，我收到以下错误：
org.eclipse.emf.common.util.WrappedException： org.xml.sax.SAXParseException： cvc-elt.1： 找不到元素 'ejb-jar' 的声明。
如果我从 ejb 3 jar 中删除 ejb-jar.xml，部署成功。如果我部署一个只包含 ejb 3 jar 的耳朵，它是成功的。如果我直接从 IBM 控制台部署 ejb 3 jar，它将成功部署。
但是尝试部署同时包含 ejb 2 和 ejb 3 jar 的耳朵是失败的。以下是完整的堆栈跟踪：

我相信部署失败了，因为耳朵同时有 ejb 2 和 ejb 2 jar。
关于如何解决此问题的任何建议？
您的 XML 标头使用了不兼容的xmlns和version属性。 试试这个：
<ejb-jar version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd">
(您的 EJB 2.x ejb-jar.xml 也可能不匹配，因此显示它也可能很有用。
