Working with Local EJB Services

The Axis EJB provider also works with local EJB components as well as remote EJB

components. In order for the local EJB version to work, the EJB components have to

be co located with the Web Application. It s actually easier to work with Local EJB

components since there are less parameters in the Axis Web Services Deployment

Descriptor. Here is an example Axis Web Services Deployment Descriptor that works

with a local EJB version of your EJB component.

xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

value="rickhightower.axis.ejb.tutorial.HelloLocalHome"/>

value="rickhightower.axis.ejb.tutorial.HelloLocal"/>

Notice that you do not have to specify the JNDI entries for the JNDI context factory or

the JNDI URL. You just have to specify where the local EJB component is mapped into

the environment naming context (ENC) of the Web application. The Axis EJB provider

will look up the local EJB component in the ENC, call the create method on the home,

and invoke methods on the EJB just like the RPC provide does with a POJO.

Of course if you are going to use a Local EJB component, you need to define a local

interface, a local home interface, add them to your

ejb jar.xml

, and add an

ejb local ref

to your

web.xml

file.

Here is the

ejb local ref

you need to add to

web.xml

the following:

ejb/Hello

Session

rickhightower.axis.ejb.tutorial.HelloLocalHome

rickhightower.axis.ejb.tutorial.HelloLocal

ejbclient.jar#Hello
