我想在JBoss AS 7.1.1.Final中爲MongoDB使用EclipseLink NoSql持久性。通過EclipseLink實現的MongoDB持久性NoSql JBoss AS 7.1.1.Final
我試圖使用EntityManager，如：
EntityManager em = Persistence.createEntityManagerFactory("mongo")
.createEntityManager();
Model m = new Model();
em.getTransaction().begin();
em.persist(m);
em.getTransaction().commit();
這裏是我的persistence.xml
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
<persistence-unit name="mongo" transaction-type="RESOURCE_LOCAL">
<class>com.Model</class>
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<properties>
<property name="eclipselink.ddl-generation" value="dorop-and=create=tables" />
<property name="eclipselink.target-database"
value="org.eclipse.persistence.nosql.adapters.mongo.MongoPlatform" />
<property name="eclipselink.nosql.connection-spec"
value="org.eclipse.persistence.nosql.adapters.mongo.MongoConnectionSpec" />
<property name="eclipselink.logging.level" value="FINEST" />
</properties>
</persistence-unit>
</persistence>
我加入的EclipseLink模塊到我的JBoss的安裝使用說明書規定here。我還在EclipseLink modules.xml中添加了javax.resource.jar作爲依賴項，併爲javax.resource創建了一個JBoss模塊。 如果有任何方法可以避免將模塊添加到JBoss中，而是將其放入我的戰爭中，那麼請讓我知道。
這是我目前遇到的問題，這很奇怪，因爲我知道它正在加載javax.resource.jar（在沒有它之前我得到了一個不同的錯誤）以及缺少的javax.resource.cci.ConnectionFactory類在那裏。

最近將添加到persistence.xml並將eclipselink.jar添加到JBoss模塊 - 更新了包版塊。 –

錯誤是因爲加載類時無法找到ResourceException類。這是因爲EclipseLink嘗試使用應用程序類加載器加載「MongoPlatform」類，然後在使用它創建新實例時發生異常。不幸的是，缺少的ResourceException類意味着實際的異常不能被拋出。嘗試確保將javax.resource添加爲EclipseLink模塊依賴項 – Chris 2012-07-16 16:32:28
@Chris - Man ...上週我做了這個，但是我弄糟了javax/resource的modules.xml。更新了包版並添加了步驟。謝謝！ – 2012-07-16 16:53:34
