EJB: static references on a LocalHome
Posted on 2002-06-21
we are in need of some sort of utility class that resolves finder functionality for us. This should provide methods in the form of findXXXByPK(String) or findYYYByName(String), returning a local reference.
We have some different opinions on how to code this best, considering performance and "political correctness" of the code and code placement.
The first version would be a stateless session bean that instantiates all necessary home interfaces in the ejbCreate() method to use them later. Advantage: clean, nice code. Disadvantage: Every SessionBean using this SessionBean needs to make a new JNDI lookup to get this utility class.
Second version is a regular class (not an EJB) that can be accessed statically to provide these methods. This class would instantiate the relevant home interfaces in a static context and call find methods on these home interfaces from its static methods. Advantage: probably better performance than first version and easier access without JNDI lookup. Disadvantage: I am not sure if those static home interfaces are evil.
I know this might be an ethical question about code beauty, but I would like to hear some input on this.
