升级Netbeans中的eclipselink 2.4

Question

Hi我将Eclipse链接升级到2.4。但我得到了这个输出。我很关心这个消息："（Eclipse Persistence Services-2.3.0.v20110604-r9504）"

这是否意味着我将再次使用2.3库？

Answer 1

是的，这意味着您使用的是旧版本。你可能错过了一个罐子，或者忘记删除旧的。

以下是如何在Glassfish中更新EclipseLink的简短分步说明：

1. 从下载EclipseLink OSGI捆绑包http://www.eclipse.org/eclipselink/downloads/.当前版本是2.5.1，您要下载的文件是EclipseLink 2.5.1 OSGi Bundles Zip (19 MB)

2. 转到$GLASSFISH_HOME/glassfish/modules并删除以下文件：

   • org.eclipse.persistence.antlr.jar
   • org.eclipse.persistence.jpa.jar
   • org.eclipse.persistence.asm.jar
   • org.eclipse.persistence.jpa.modelgen.jar
   • org.eclipse.persistence.core.jar
   • org.eclipse.persistence.oracle.jar
   • javax.persistence.jar

3. 打开下载的ZIP文件，将以org.eclipse.persistence开始但不包含source的所有内容（这些是源，您可能不需要它们）和文件javax.persistence_2xxx.jar提取到文件夹$GLASSFISH_HOME/glassfish/modules

4. 重新启动Glassfish，您就完成了
