启动jboss时的问题：

项目结构：Ear,Ejb,EjbClient,Web,JPA Project 共5个project在eclipse中
启动jboss就出错：--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:ear=MyiBuyEar.ear,jar=MyiBuyEjb.jar,name=LoginRegisterBean,service=EJB3
  State: NOTYETINSTALLED
  I Depend On:
    persistence.units:unitName=MyiBuyJPAObjectName: jboss.j2ee:ear=MyiBuyEar.ear,jar=MyiBuyEjb.jar,name=ManageCartBean,service=EJB3

  Depends On Me:
    jboss.j2ee:ear=MyiBuyEar.ear,jar=MyiBuyEjb.jar,name=LoginRegisterBean,service=EJB3
    jboss.j2ee:ear=MyiBuyEar.ear,jar=MyiBuyEjb.jar,name=ManageCartBean,service=EJB3persistence.xml在JPA project中，内容大致如下：<persistence-unit name="MyiBuyJPA" transaction-type="JTA">
<jta-data-source>java:/testDS</jta-data-source>
<class>xxx</class>
</persistence-unit>
mysql-ds.xml在%JBOSS_HOME%server\default\deploy下，大致内容如下：<local-tx-datasource>
<jndi-name>testDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf-8</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
</local-tx-datasource>第一次new jpa project,求大神解答...
