Hi,
I am having a problem looking up for jndi from my webapp. I am using
jboss-4.0.4.CR2 and java 1.5. Right now in my application I don't have any
ejb's. I only have a few servlets. My application is currently bundled as a
.war file.
The jndi configuration I have is as follows:
web.xml
<resource-env-ref>
| <resource-env-ref-name>QuestionWriter1</resource-env-ref-name>
|
<resource-env-ref-type>com.mycompany.survey.QuestionWriter1</resource-env-ref-type>
| </resource-env-ref>
I have several QuestionWriters.
In the jboss-web.xml my config is
<resource-env-ref>
| <resource-env-ref-name>QuestionWriter1</resource-env-ref-name>
| <jndi-name>java:/QuestionWriter1</jndi-name>
| </resource-env-ref>
I have a resource-env-ref in jboss-web for each resource-env-ref tag in the
web.xml
The way I look in my code is
Context env = (Context) new InitialContext().lookup("java:comp/env");
| qw = (QuestionWriter) env.lookup("QuestionWriter1");
Can anyone tell me what is that I am doing wrong. I try to look into the jndi
view in the jmx-console and I dont find any of there QuestionWriters.
Is there any other configuration I am missing. I place my war file in the
deploy folder of jboss. I am using the ejb3-clustered instance of jboss this is
because in the future we are going to have ejb's.
The exception it throws is as follows
javax.naming.NamingException: Could not dereference object [Root exception is
javax.naming.NameNotFoundException: QuestionWriter1 not bound]

I have the same code running in tomcat with the <Resource tag in the server.xml
of tomcat.
Thanks in advance.
