我正在尝试使用这些特定技术部署和运行项目：
EJB3.1 Eclipse 链接 2.4、JDBC 14。Oracle 10g。SJBOSS 7.Java EE 6
自 4 天以来，我一直在尝试制作一个 Hello World 示例，但我还没有运行它，现在我遇到了一些奇怪的错误。
这是我到目前为止所做的：
我们在 Jboss 中创建了 Eclipse Link 模块
所以我在 Jboss 中创建了模块，这样我就可以访问 oracle 数据库：
<module xmlns="urn:jboss:module:1.0" name="org.eclipse.persistence">
<resources>
<resource-root path="eclipselink.jar"/>
<!-- Insert resources here -->
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.persistence.api"/>
<module name="javax.transaction.api"/>
<module name="javax.validation.api"/>
<module name="javax.xml.bind.api"/>
<module name="org.antlr"/>
<module name="org.apache.commons.collections"/>
<module name="org.dom4j"/>
<module name="org.javassist"/>
<module name="org.jboss.logging"/>
<module name="com.oracle.ojdbc14"/>
</dependencies>
</module>
之后，我在 xml 文件中为 oracle 数据库创建了模块
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="com.oracle.ojdbc14">
<resources>
<resource-root path="ojdbc14.jar"/>
<!-- Insert resources here -->
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
finally i changed the Standalone.xml, this is the part of the standalone that i changed:
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
<datasources>
<datasource jndi-name="java:/EclipseLinkDS" pool-name="EclipseLinkDS" enabled="true" jta="true" use-java-context="true" use-ccm="true">
<connection-url>
jdbc:oracle:thin:localhost:1521:TOPLINK
</connection-url>
<driver>

</driver>
<transaction-isolation>

</transaction-isolation>
<pool>
<prefill>

</prefill>
<use-strict-min>

</use-strict-min>
<flush-strategy>

</flush-strategy>
</pool>
<security>
<user-name>

</user-name>
<password>

</password>
</security>
</datasource>
<drivers>
<driver name="oracle" module="com.oracle.ojdbc14">
<driver-class>

</driver-class>
<xa-datasource-class>
oracle.jdbc.xa.client.OracleXADataSource
</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
当我在 Eclipse 上运行 EJB PROJECT 时，出现以下错误：

任何人都知道我该如何解决？我只需要建立一个良好的连接，以便能够开发完整的应用程序运行。
如果您有小费或其他东西，将不胜感激。
