Re: [JBoss-user] java:/comp/env problems?
The java:comp/env namespace is a J2EE notion that applies to both J2EE ejb web components. The ejb spec goes into some detail on this and the j2ee spec generalizes this. The servlet spec briefly mentions the java:comp/env namespace and defers to the j2ee spec. - Original Message - From: Guy Rouillier [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, May 11, 2001 2:44 PM Subject: Re: [JBoss-user] java:/comp/env problems?

Re: [JBoss-user] java:/comp/env problems?
I've had trouble with lookups from web componenets to the comp/env space if
I don't have a jboss-web.xml file included in my WEB-INF directory. Try in
cluding an empty jboss-web.xml file, like this:
?xml version=1.0?
jboss-web/
I included one, and my lookups suddenly worked. (see a post I
dyslexically named env-entry JDNI name)

Hi all,
I'm having a problem where my JSP can't find my ejb
when in the java:comp/env namespace in JBoss.
In using the pre-configured/bundled
JBoss-2.2.1_Tomcat-3.2.1 on RedHat Linux 7.0 (intel),
JDK 1.3.0_02, and my EAR I created using the
deploytool deploys fine on j2eesdk1.2.1. It's a
simple app: a jsp looks up a stateless session ejb
which looks up a DataSource pointing at Oracle 8i. I
followed the online docs to the T to set up the
OracleDS.
I've included the pertinant files, but basically, it
doesn't
look like the jsp can find the ejb when I reference it
with java:comp/env/... If I change my references back
to not use java:comp/env/, it works on jboss but not
on j2eesdk. How can an EAR be completely J2EE
portable when this happens? Any suggestions?
Also, another problem I'm having though is
that (when I change my code so it can find the ejb) my
ejb can't seem to find the datasource, though
it can in the j2eesdk. Is there something wrong with
my jboss.xml file?
Thanks for any help (and sorry for the long include
below)...

Re: [JBoss-user] java:/comp/env problems?
For the jsp issue you need to include a jboss-web.xml descriptor in the WEB-INF dir to map the ejb-refs in the web-app.xml descriptor to the deployment jndi name: jboss-web ejb-ref ejb-ref-nameejb/UserAuthority/ejb-ref-name jndi-nameejb/UserAuthority/jndi-name /ejb-ref /jboss-web Your jboss.xml is missing: resource-managers resource-manager res-class=javax.sql.DataSource res-nameOracleDS/res-name res-jndi-namejava:/OracleDS/res-jndi-name /resource-manager /resource-managers - Original Message - From: David Ward [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, May 11, 2001 6:38 AM Subject: [JBoss-user] java:/comp/env problems?

Re: [JBoss-user] java:/comp/env problems?
Scott, Thanks! That got rid of all my problems. It now finds everything, all the way down to the datasource, fine. Does anyone know where on the jboss site there are docs that talk about the jboss-web.xml file? There's a big DTD gif outlining jboss.xml, but I dont' remember reading anything about jboss-web.xml...

Re: [JBoss-user] java:/comp/env problems?
Integrated support for jboss-web.xml independent of the web container was just added recently and so has not been documented. The dtd is available in the jboss cvs module as src/resources/org/jboss/metadata/jboss-web.dtd which can be obtained online at sourceforge. - Original Message - From: David Ward [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Friday, May 11, 2001 11:52 AM Subject: Re: [JBoss-user] java:/comp/env problems?
