Ejb-handler Handler

It is responsible for persisting the object via a stateless session bean. The following attributes are supported:

Attribute
Usage

jndi

JNDI path to EJB Home interface

if

EL expression that must be evaluated to true prior to handler action

unless

  EL expression that must be evaluated to false prior to handler action

Inside the handler, you should specify the suitable insert-method, delete-method and update-method tags. There is a mandatory attribute named method. This attribute must contain the name of the method to invoke. Additionally, the parameters to use can be specified. The following example shows an ejb-handler that uses an EJB whose only parameter is the data object:

<datanode name="network">
    <ejb-handler jndi="com.soffid.sample/NetworksBean">
        <insert-method method="insert"/>
        <delete-method method="delete"/>
        <update-method method="update"/>
    </ejb-handler>
        ...
</datanode>

This second example shows how to call a method with slightly complex parameters:

<datanode name="acl">
    <ejb-handler jndi="com.soffid.sample/NetworksBean" >
        <insert-method method="grant">
            <parameter value="${parent.instance}"/>
            <parameter value="${instance}"/>
        </insert-method>
        <delete-method methos="revoke"> 
            <parameter value="${instance}"/>
        </delete-method>
    </ejb-handler>
</datanode>
