All Implemented Interfaces:

ActionLifecycle

public class EJBProcessor
extends AbstractActionLifecycle

EJBProcessor is an action that can call stateless session beans deployed in an application server.

This implementation currently supports EJB2.x and EJB3.x session beans. Example EJB 2.x configuration:

<action name="EJBTest" class="org.jboss.soa.esb.actions.EJBProcessor">
    <property name="ejb-name" value="MyBean" />
    <property name="jndi-name" value="ejb/MyBean" />
    <property name="initial-context-factory" value="org.jnp.interfaces.NamingContextFactory" />
    <property name="security-principal" value="username" />
    <property name="security-credentials" value="password" />
    <!-- Optional property for JAAS login -->"
    <property name="security-login-module" value="securityDomain" />
    <property name="provider-url" value="localhost:1099" />
    <property name="method" value="login" />

    <!-- Optional output location, defaults to "DEFAULT_EJB_OUT"
    <property name="esb-out-var" value="MY_OUT_LOCATION"/> -->
    <property name="ejb-params">
    <!-- arguments of the operation and where to find them in the message -->
        <arg0 type="java.lang.String">username</arg0>
        <arg1 type="java.lang.String">password</arg1>
    </property>
 </action>
 

Example EJB 3.x configuration:

<action name="EJBTest" class="org.jboss.soa.esb.actions.EJBProcessor">
    <property name="ejb3" value="true" />
    <property name="jndi-name" value="ejb/MyBean" />
    <property name="initial-context-factory" value="org.jnp.interfaces.NamingContextFactory" />
    <property name="security-principal" value="username" />
    <property name="security-credentials" value="password" />
    <!-- Optional property for JAAS login -->"
    <property name="security-login-module" value="securityDomain" />
    <property name="provider-url" value="localhost:1099" />
    <property name="method" value="login" />

    <!-- Optional output location, defaults to "DEFAULT_EJB_OUT"
    <property name="esb-out-var" value="MY_OUT_LOCATION"/> -->
    <property name="ejb-params">
    <!-- arguments of the operation and where to find them in the message -->
        <arg0 type="java.lang.String">username</arg0>
        <arg1 type="java.lang.String">password</arg1>
    </property>
 </action>
