RE: ejb NameNotFound exception?

Hi,

If the web application and ejb are bundled together in an ear file as you mentioned earlier in your post, you may want to use ejb-local-ref tag instead.

From Aaron’s book:

The ejb-local-ref element is used to connect to an EJB through its local home and local interfaces.

The EJB is usually defined in the same EAR as the web application, though it may also be in an

EJB JAR or application EAR which is defined as a parent of the current application.

If so, the web.xml in magicgball sample can be served as an example:

<ejb-local-ref>

<ejb-ref-name>mGball</ejb-ref-name>

<ejb-ref-type>Session</ejb-ref-type>

<local-home>org.acme.MagicGBallLocalHome</local-home>

<local>org.acme.MagicGBallLocal</local>

<ejb-link>magicGball-ejb-1.0.jar#MagicGBall</ejb-link>

</ejb-local-ref>

Thanks,

Lin

Hi Kristian,

I think you need a ejb-ref tag in web.xml .

    <ejb-ref>
    <ejb-ref-name>Simple</ejb-ref-name> 
    <ejb-ref-type>Session</ejb-ref-type>
    <home>ejbs.SimpleHome</home>
    <remote>ejbs.Simple</remote>
    </ejb-ref>

and ic.lookup("java:comp/env/Simple") should be able to find the EJB.

Let me know if this works.

Regards,
Vamsi

Hmmm. :) Okay, here we go:

geronimo-web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-1.0 "
xmlns:nam="http://geronimo.apache.org/xml/ns/naming-1.0"
xmlns:sec="http://geronimo.apache.org/xml/ns/security-1.1 "
xmlns:sys="http://geronimo.apache.org/xml/ns/deployment-1.0"
configId="SimpleWeb/SimpleWeb">
  <context-root>/SimpleWeb</context-root>
  <context-priority-classloader>false</context-priority-classloader>
</web-app>

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version=" 2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance "
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd ">
        <display-name>
        SimpleWeb</display-name>
        <welcome-file-list>
                <welcome-file>index.html</welcome-file>
                <welcome-file> index.htm</welcome-file>
                <welcome-file>index.jsp</welcome-file>
                <welcome-file>default.html</welcome-file>
                <welcome-file>default.htm </welcome-file>
                <welcome-file>default.jsp</welcome-file>
        </welcome-file-list>
</web-app>

The web application, the Bean and the BeanClient module are packaged
into an EAR with

geronimo-application.xml:

<?xml version="1.0" encoding="UTF-8"?>
<application
xmlns=" http://geronimo.apache.org/xml/ns/j2ee/application-1.0"
xmlns:sec="http://geronimo.apache.org/xml/ns/security-1.1"
xmlns:sys=" http://geronimo.apache.org/xml/ns/deployment-1.0"
application-name="SimpleBeanEAR" configId="SimpleBeanEAR/SimpleBeanEAR"/>

and application.xml:

<?xml version=" 1.0" encoding="UTF-8"?>
<application id="Application_ID" version="1.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/application_1_4.xsd">
        <display-name>
        SimpleBeanEAR</display-name>
        <module>
                <ejb>SimpleBean.jar</ejb>
        </module>

        <module>
                <web>
                        <web-uri>SimpleBeanWeb.war</web-uri>
                        <context-root>SimpleBeanWeb</context-root>
                </web>
        </module>
</application>

respectively. I have to admit I haven't modified any of these by now,
since I'm just slowly starting to understand the meaning of the vast
bunch of deployment-related xml files, so I relied upon xdoclect to
create things the way they should be... *blush*

TIA and bye,
Kris
