Re: [JBoss-user] Question about B2B and <ejb-ref>

[Julien V. <jul...@ya...>]

Ejb-ref is bound to java:comp/env so getting an ejbHome is
ctx.lookup("java:comp/env/" + name); where
name is enclosed in ejb-ref-name tag.
But you can retrieve an ejbHome from global jndi without prefixing with
"java:comp/env/"

in your caller : home = ctx.lookup(name);

for the called in jboss.xml <session> ... <jndi-name>name<jndi-name> ...
</session>

therefore you don't have to redeploy you caller each time.
