Remove EJB-ref from old applications ?

[developer251]

Hi all !

I have an older Java EE 5 application which is made up of EJB 3 (placed in a jar file) and a Web application. The web application is bundled in an EAR file.

The web.xml file contains references to the EJB files:

<ejb-ref>

        <ejb-ref-name>ejb/TelcoController</ejb-ref-name>

        <ejb-ref-type>Session</ejb-ref-type>

        <home></home>

        <remote></remote>

</ejb-ref>

and jboss-web.xml contains as well references to EJB files:

<ejb-ref>

        <ejb-ref-name>ejb/TestController</ejb-ref-name>

        <jndi-name>ejb/TestController/local</jndi-name>

</ejb-ref>

Now I'm going to port this application to JBoss 7: does it make sense to remove all ejb-refs both in web.xml and jboss-web.xml and replace the Context lookup with with injection ?

@EJB

TelcoController

Will this work both if the EJB is a remote and if it's a local one ?

Thanks

yes, you can replace ejb-ref or ejb-local-ref elements with @EJB or @Inject, but in most cases, it's not worth the risk and efforts.

It should work both and it's up to you what way you'll choose.

Just a note - you'll need to change the jndi-name properly to work with JBoss 7.
