成功部署了一个cmp,但client调用时说:"ArrayIndexOutOfBoundsException:"

已经和数据库关联上了,weblogic显示部署成功,如果用java程序访问,代码:
////////////////////testclient.java//////////////////////////////

Properties pro=new Properties();
pro.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
pro.put(Context.PROVIDER_URL,
"t3://127.0.0.1:7001");
pro.put(Context.SECURITY_PRINCIPAL,
"Employees");
Context ctx=new InitialContext(pro);
System.out.println(
"Debug...");
Object obj=ctx.lookup(
"CustomerEJB");
System.out.println(
"after lookup...");
CustomerHomeRemote home=(CustomerHomeRemote)PortableRemoteObject.narrow(obj,CustomerHomeRemote.class);
//create customers
Integer primary=new Integer(1);

CustomerRemote remote=home.create(primary);
remote.setFirstName(
"lyo");
remote.setLastName(
"Yashnoo");
CustomerRemote customer=home.findByPrimaryKey(primary);
String first=customer.getFirstName();
String last=customer.getLastName();
System.out.println(
"first name is"+first);
System.out.println(
"=================");
System.out.println(
"last name is"+last);

///////////////////////////////////////////////////////////
,则说:“Debug...
javax.naming.NamingException: Unhandled exception in lookup [Root exception is j
ava.lang.NullPointerException]”
如果写在jsp中在weblogic中访问,则控制台报错说:
“javax.naming.AuthenticationException [Root exception is javax.security.auth.logi
n.FailedLoginException: [Security:090304]Authentication Failed: User Employees j
avax.security.auth.login.FailedLoginException: [Security:090302]Authentication F
ailed: User Employees denied]

但是我的ejb-jar.xml和weblogic-ejb-jar.xml是授权了的:
///////////////////////////////////////////////
ejb-jar.xml
/////////////////////
..................
<assembly-descriptor>
<security-role>
<role-name>Employees</role-name>
</security-role>
<method-permission>
<role-name>Employees</role-name>
<method>
<ejb-name>CustomerEJB</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>
.....................

weblogic-ejb-jar.xml
//////////////////////////////////

<security-role-assignment>
<role-name>Employees</role-name>
<principal-name>Employees</principal-name>
</security-role-assignment>
................................

以上不就是授权Employees可以访问所有方法,且它的密码为空吗?
而且用weblogic的系统管理员都不能访问!在weblogic中的security的group中我也加了Employees,还是不行,weblogic在哪里设密码?

我的数据库中游一条纪录,如果我把“Context.SECURITY_PRINCIPAL,"Employees");”去掉,jsp又报错说:
"java.lang.ArrayIndexOutOfBoundsException: 13"
为什麽数组越界了?访问的的确就是第一条数据

如果去掉Context.SECURITY....,java控制台程序报错:"Debug...
after lookup...
Exception in thread "main" java.lang.AbstractMethodError: lyo.cmp.customer._Cust
omerHomeRemote_Stub.create(Ljava/lang/Integer;)Llyo/cmp/customer/CustomerRemote;"
谁能解释一下为什麽会越界?
