java - Websphere 85 ejb 3 部署问题

Question

我正在尝试在 websphere 8 上部署一个 ejb 3 的 bean。Bean 实现位于 src/main/java 中，ejb-jar.xml 位于 src/main/resources/META-INF 中。它被打包在一个 jar 中，并且该 jar 包含在 Ear 中，ear 中还有其他带有 ejb 2 的 ejb jar。所以 Ear 包含 ejb 2 和 ejb 3 jar。在 websphere 中部署此 Ear 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，则部署成功。如果我部署只包含 ejb 3 jar 的 Ear，则成功。如果我直接从 ibm 控制台部署 ejb 3 jar，它就会成功部署。

但是尝试部署包含 ejb 2 和 ejb 3 jar 的 Ear 失败了。以下是完整的堆栈跟踪:

我认为部署失败是因为 Ear 同时具有 ejb 2 和 ejb 2 jar。

关于如何解决这个问题有什么建议吗？

Answer 1

您的 XML header 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，因此显示这一点也可能有用。)
