Websphere 85 ejb 3部署问题

Question

我试图在websphere 8上部署ejb 3的bean。Bean实现位于src/main/java中，ejb-jar.xml位于src/main/resources/META-INF 。 这是包装在一个罐子里，罐子也包含在耳朵里，也有其他ejb罐子与ejb 2.因此，耳朵包含ejb 2和ejb 3罐子。 在这款耳塞在WebSphere的部署，我收到以下错误：

org.eclipse.emf.common.util.WrappedException：org.xml.sax.SAXParseException：CVC-elt.1：找不到声明元素'ejb-jar'。

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。

但试图部署包含ejb 2和ejb 3 jar的耳朵失败。下面是完整的堆栈跟踪：

ejb-jar.xml中 <ejb-jar xmlns="http://java.sun.com/xml/ns/j2ee" 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" version="3.0"> <description><![CDATA[]]></description> <display-name></display-name> <enterprise-beans> <session id=""> <description><![CDATA[]]></description> <ejb-name></ejb-name> <env-entry> <env-entry-name></env-entry-name> <env-entry-type></env-entry-type> <env-entry-value><![CDATA[]]></env-entry-value> </env-entry>

我相信部署失败，因为耳朵既有EJB 2和EJB 2罐。

有关如何解决此问题的任何建议？

您的XML标题使用不兼容的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的ejb-jar.xml中也可能有不匹配，所以显示也可能有用）
