网上有和我报错一样的，但是按照他们给的方法不能解决，报错如下
21:31:26,734 ERROR [URLDeploymentScanner] Incomplete Deployment listing:
--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:jar=jpa_01.jar,name=PersonManagerBean,service=EJB3
State: NOTYETINSTALLED
I Depend On:
persistence.units:unitName=test
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:unitName=test
State: NOTYETINSTALLED
Depends On Me:
jboss.j2ee:jar=jpa_01.jar,name=PersonManagerBean,service=EJB3
网上给的解决办法是
1,Copy "mysql-connector-java-5.0.8-bin.jar"到"#\jboss-4.2.2.GA\server\default\lib"下
2,Copy "mysql-ds.xml"到"#\jboss-4.2.2.GA\server\default\deploy"下
我走做过了，但是没有效果。
我值部署了一个实体Bean，JPA。
注入了一下EntityManager
@PersistenceContext(unitName ="test")
protected EntityManager em ;
就报这个错误！
那位知道帮忙解决一下，急！！！谢谢

哎，你给的信息好像不多，看不出来什么呢
------解决方案--------------------
比如说，你的 ds 文件是怎么写的，你的 Session Bean 代码是什么

继续关注！

把这个
<jta-data-source>java:MySqlDS</jta-data-source>
改成这个再试试看，也就是在冒号后面加个“/”
<jta-data-source>java:/MySqlDS</jta-data-source>
