InstantiationException

[jzhang]

I created a BMP entity bean and try to access it from a session bean. In session bean, I have code:
Context lContext = new InitialContext();
OrderListEntityHome lHome = (OrderListEntityHome) PortableRemoteObject.narrow(
lContext.lookup(
"java:comp/env/ejb/OrderListEntity"),OrderListEntityHome.class);
OrderListEntityData lData=new OrderListEntityData();
OrderListEntity lEntity=lHome.create(lData);
When run in JBoss 3.0, it throw out "Could not instantiate bean, nested exception is InstantiationException "
Any ideas?
Thanks,

Jian

This means that JBoss was unable to create an instance of your ejb implementation class. Do you have constructors in your ejb class? Constructors are not allowed.

No, I do not have constructors in ebj class. I modified the example TestBMPEntityBean in the example file, and it still give me the same error. Is there anything I need to specify in build.xml file?

I don't know. I have never used BMP my self, so I don't know. Maybe someone else can help you.

Ok, I finally figured it out. I need to add <entitybmp/> tag in build.xml file so ant will generate correct ejb xml file. Thanks though.
