我在AS JBOSS 7上启动EJB应用程序时遇到问题，或者在使用JBoss AS 7.2启动EJB应用程序时遇到问题，同时关联EJB和persistenceUnit之间的依赖关系 .
行日志错误：
10：07：04,857错误[org.jboss.as.deployment]（DeploymentScanner-threads - 1）{“复合操作失败并被回滚 . 失败的步骤：”=> {“操作步骤-2”=> { “缺少/不可用依赖项的服务”=> [“jboss.deployment.unit . \”crm.war \“ . component.ClienteDAOBean.START缺少[jboss.naming.context.java.module.crm.crm . \”env /br.com.crm.model.dao.ClienteDAOBean/em \“]”，“jboss.persistenceunit . \”crm.war＃crmUnity \“missing [jboss.naming.context.java.jboss.datasources / CRMDS]” ，“jboss.deployment.unit . \”crm.war \“ . jndiDependencyService缺失[jboss.naming.context.java.module.crm.crm . \”env / br.com.crm.model.dao.ClienteDAOBean / em \“，jboss.naming.context.java.module.crm.crm . \”env / br.com.crm.model.dao.ContatoDAOBean / em \“]”，“jboss.deployment.unit . \”crm . war \“ . component.br / com / crm / model /dao / ColatoDAORemote.START缺少[jboss.naming.context.java.module.crm.crm . \”env / br.com.crm.model.dao.ContatoDAOBean / em \“]”]}}}
下面，遵循xml文件和EJB代码：
application.xml中

项目技术：
嵌入式HSQDB数据库版本2.2.3
EJB 3
JPA 2.1
HIBERNATE 3提供JPA持久性
任何人都可以帮我解决这个依赖问题吗？
先感谢您 .

如果您将数据源的别名放在耳中，并将它们配置在standalone.xml中，那将是完美的：在理想情况下，您可以获得独立于数据库的分布 . 尝试在standalone.xml中插入此块（我从crm-ds.xml中获取参数）：
子系统的版本可以是服务器特定的 .
