CMP home business method

[schwarcz]

Sorry to ask such a naive question, but I’m trying to do something I thought would be trivial, but JBoss doesn’t like it and I can’t figure it out…

I have an cmp entity bean to which I want to add a home method that is not linked to a any EJB QL. I’ve reduced it to what should be a minimal example. Can anybody shed any light on this? The Sun verifier doesn’t have any specific complaints the way JBoss does.

The local home interface (QuoteLocalHome) contains:

public String xyz ();

The bean implementation class (QuoteBean) contains:

public String xyz () { return "oops"; }


And yet JBoss is permanently unhappy about this:


16:27:53,781 INFO [EJBDeployer]

Bean : Carl/QuoteEJB
Method : public abstract String xyz()
Section: 12.2.11
Warning: Each local home method must match a method defined in the entity bean class.

You need ejbHomeXyz() in the QuoteBean.

>Method : public abstract String xyz()
>Section: 12.2.11
>Warning: Each local home method must match a method defined in the entity bean class.

The section 12.2.11 of the ejb 2.0 spec states as follows:

Home methods can have arbitrary names, provided that they do not clash with create, find and
remove method names. The matching ejbHome method specified in the entity bean class must have
the same number and types of arguments and must return the same type as the home method as specified
in the local home interface of the bean.

And the ejbHome is defined in 12.2.6.

An ejbHome(...) method must exist for every home (...) method on the
entity bean's remote home or local home interface. The method name must have ejbHome as its prefix
followed by the name of the method in which the first character has been uppercased.
