h3. <binding.ejb>

Tuscany provides the reference-side support for the [SCA EJB Session Bean Binding V1.00|http://www.osoa.org/download/attachments/35/SCA_EJBSessionBeanBinding_V100.pdf?version=1].
It allows SCA components to access existing stateless session beans.

The XML configutation

To access a stateless session, the uri attribute of the <binding.ejb> element needs
to be be configured with a JNDI name. 

{code}
<binding.ejb uri="corbaname:iiop:1.2@localhost:1050#AddServiceBean" />
{code}

Depending on which enviroment the SCA components are hosted, various styles of the JNDI names
can be supported:
* relative JNDI
* java:comp/env/<ejb-ref>
* corbaname JNDI

Some examples
{code}
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" name="account">
<!-- composite refrence with ejb binding. Modify host and port number in uri attribute
based on where you have installed target ResumeBank EJB -->
<component name="CustomerComponent">
<implementation.java class="account.CustomerImpl" />
<reference name="extEJBService">
<!-- To use the CosNaming, use the following URI -->
<!-- <binding.ejb uri="corbaname:iiop:1.2@localhost:1050#AddServiceBean" />-->
<binding.ejb uri="hello-addservice/AddServiceBean/calculator.AddService" />
</reference>
</component>
</composite>
