Seam in JBoss Application Server set EJB session bean to Seam component dose not need set any JNDI. Seam can find out EJB’s JNDI.

In Websphere 7 Application Server, Seam cannot find out EJB’s JNDI. Need manual set the EJB’s JNDI (Only set EJB session bean with Seam component).

First, add below setting in web.xml:

<ejb-local-ref>
    <ejb-ref-name>ejblocal:EjbSynchronizations</ejb-ref-name>
    <ejb-ref-type>Session</ejb-ref-type>
    <local-home></local-home>
    <local>org.jboss.seam.transaction.LocalEjbSynchronizations</local>
</ejb-local-ref>

Then, add a seam-jndi.prpperties file in WEB-INF/classes:

com.ibm.websphere.naming.hostname.normalizer=com.ibm.ws.naming.util.DefaultHostnameNormalizer
java.naming.factory.initial=com.ibm.websphere.naming.WsnInitialContextFactory
com.ibm.websphere.naming.name.syntax=jndi
com.ibm.websphere.naming.namespace.connection=lazy
com.ibm.ws.naming.ldap.ldapinitctxfactory=com.sun.jndi.ldap.LdapCtxFactory
com.ibm.websphere.naming.jndicache.cacheobject=populated
com.ibm.websphere.naming.namespaceroot=defaultroot
com.ibm.ws.naming.wsn.factory.initial=com.ibm.ws.naming.util.WsnInitCtxFactory
com.ibm.websphere.naming.jndicache.maxcachelife=0
com.ibm.websphere.naming.jndicache.maxentrylife=0
com.ibm.websphere.naming.jndicache.cachename=providerURL
java.naming.provider.url=corbaloc:rir:/NameServiceServerRoot
java.naming.factory.url.pkgs=com.ibm.ws.runtime:com.ibm.ws.naming

Modify components.xml:

<core:init 
    jndi-pattern="ejblocal:#{ejbName}" 
    debug="false" />

Last step is add ibm-ejb-jar-bnd.xml in EJB project’s META-INF:

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar-bnd xmlns="http://websphere.ibm.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee 
                      http://websphere.ibm.com/xml/ns/javaee/ibm-ejb-jar-bnd_1_0.xsd"
    version="1.0">
    <session name="MyBean" simple-binding-name="MyBean" />

</ejb-jar-bnd>

simple-binding-name is a JNDI. Seam will use below JNDI to find out MyBean:

ejblocal:MyBean

If modify jndi-pattern. you must modify simple-binding-name too.

For example:

<core:init 
    jndi-pattern="ejblocal:myModule/#{ejbName}" 
    debug="false" />

simple-binding-name also modify as:

<session name="MyBean" 
    simple-binding-name="myModule/MyBean" />
