RE: EJB using "core" classes?
Thanks. That at least clears this up. What if I EAR the whole thing and deploy the EAR? Would the EJB then be able to see the classes..or at that wouldn't make any difference? > -Original Message- > From: Robert Krueger [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, November 15, 2000 9:20 AM > To: Orion-Interest > Subject: Re: EJB using "core" classes? > > > > > > >At any rate..my main question here is, the EJB class in the > jar file is > >referencing the core class.

Re: EJB using "core" classes?
Uhh ... isn't this unnecessarily vendor-specific? I've had utility classes used by both web and ejb layers and I just stick them with the EJB JAR file and things seem to work out fine.

Is there some trickery to getting EJB >classes to see the WEB-INF/classes? no, it's impossible and not meant to be that way. two possible cases: - your class is not application specific but a general utility in which case you could put it in a library that is specified in the library path of global-application and therefore visible for all web an ejb modules in all application or you have to explicitly put it where the ejb code gets it - it is application specific and used by both web an ejb then you have to put it in a separate jar which you reference in orion-application.xml (or the dir it's located in, look at the library element) and it will be visible to both ejb and web modules.

EJB using "core" classes?
Hi all, I am attempting (again) deploying EJB. While I think I have the pricipals down, (still trying to figure out JNDI properties..what they are for), I am confused about one thing. I have an application named ss. In Orion I have set the path to c:\ss. There is the META-INF dir, which I have application.xml in..that points has ss.jar . It also has my web module in it that points to www (from ss..so ss/www). I compile my ejb (a simple login ejb) which seems to be ok. In the ss.jar, I have the META-INF dir with ejb-jar.xml in it accessing my com.ss.ejb.login.LoginXXX classes. These are Stateless session classes. I also have in the ejb-jar.xml file the com/ss/ejb/login/LoginSessionEJB.class, and so on. So when I start up Orion, it shows its deploying the EJB, however..it says it can't find class core/login/Login.class. Now..in my package, I have ss.core, ss.ejb, and ss.ui. ss.core.login.Login is a "bean" that I will use in both the EJB entity class, and my UI javabean class. I don't know if this is the wrong way to do it, but I figure..why put the same getter/setter methods twice (in both the UI javabean class that gets/sets the JSP page form info, and the EJB class that loads/stores the same info). I am not too familiar with EJB just yet, but I see no reason why this wouldn't work. In my entity bean, I would somehow reference the core.login.Login class, and use that reference to load/store the entity. Can that even be done? Or is the only way to get entity beans via CMP to work is directly have the methods in the entity? I would think if my methods that are used to load/store the entity use the reference to get/set the fields of the reference Login, this should be ok. At any rate..my main question here is, the EJB class in the jar file is referencing the core class. I don't have the core package in the jar file. I thought if I deployed the jar file into the same web-app as the other classes were in, it would have access to these classes. I compile classes to WEB-INF/classes. Is this not the case? Is there some trickery to getting EJB classes to see the WEB-INF/classes? Thanks for any help.
