Websphere 85 ejb 3部署問題

Question

我正在嘗試在Websphere 8上部署一個為ejb 3的bean。Bean實現位於src / main / java中，而ejb-jar.xml位於src / main / resources / META-INF中。 它包裝在一個罐子中，並且罐子也包含在耳朵中，該罐子也有其他帶有ejb 2的ejb罐子。因此，耳朵既包含ejb 2罐，也包含ejb 3罐。 在Websphere部署此耳朵期間，出現以下錯誤：

org.eclipse.emf.common.util.WrappedException：org.xml.sax.SAXParseException：cvc-elt.1：找不到元素'ejb-jar'的聲明。

如果我從ejb 3 jar中刪除ejb-jar.xml，則部署成功。 如果我部署只包含ejb 3 jar的耳朵，那就成功了。 如果我直接從ibm控制台部署ejb 3 jar，它將成功部署。

但是嘗試部署同時包含ejb 2和ejb 3 jar的耳朵是失敗的。 以下是完整的堆棧跟蹤：

我相信部署會失敗，因為ear同時具有ejb 2和ejb 2罐子。

對於如何解決這個問題，有任何的建議嗎？

Answer 1

您的XML標頭使用了不兼容的xmlns和version屬性。 嘗試這個：

<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，因此顯示出來也可能有用。）
