NameNotFoundException: Datasource not bound

[jug]

Hi,

I try to deploy an empty seam gen project on a Tomcat 6.0.16  using Seam
2.0.2.GA and an HSQLDB.
As I do not need any EJB-functionality I am not using JBoss Embaddable,
but a plain Tomcat.

I successfully tested the seam-booking example on my
Tomcat-configuration but I'm having huge trouble deploying the seam gen
projekt on my tomcat.

As you can see in the following exception, the Datasource is not bound.
My datasource-config is alright. Once I uncomment the seam
servlet-listern and the seam filters, the tomcat starts up and the
datasource is accessible.

I guess that Tomcat/seam tries to access the Datasource too early on the
server startup, which causes the failure. I'm stucked, could anyone
please help me?

I couldn't find any solution for my problen in this forum or on google...

Regards
Julian

Some quick questions for you.

What seam-booking example?  You said you do not have embedded installed - and the standard examples/booking example need it. 

Also I'm assuming that you used war setup for your app - correct?

Also from the exception it is not finding global so it is not even getting to your /OnlineZeiterfassungDatasource namespace.

tomcat6 JNDI docs talks about needed to set resource link to expose this to the web app.

Tomcat 6 maintains a separate namespace of global resources for the entire server. These are configured in the <GlobalNameingResources> element of $CATALINA_HOME/conf/server.xml. You may expose these resources to web applications by using <ResourceLink> elements.

Hope this helps,

Jay

Hi Jay,

thank you for your quick reply. I used the jboss-seam-jpa example in my previous trial.

You're assuming right. In the current project I used a war file to setup my app with seam gen. I already had a look on the Tomcat 6 JNDI docs and I recon that my datasource setup is alright. I configured the datasource as a ressource in the GlobalNamingResources section and used a ResourceLink in the Context section below.

I can access the datasource with lambdaprobe, when I start up the tomcat without the seam listners and filters. That's why I am assuming that the datasource configuration should be alright. What is your opinion?
You may have a look at the following extracts of my config files...

Extracts from the server.xml:

                    type="javax.sql.DataSource" />
        </Context>

I tried both ways, with and with-out a res-ref-name for the datasource in the web.xml: (It makes no difference)

</web-app>
...

   </security-constraint>

  <resource-ref>
      <description>DB Connection</description>
      <res-ref-name>global/OnlineZeiterfassungDatasource</res-ref-name>
      <res-type>javax.sql.DataSource</res-type>
      <res-auth>Container</res-auth>
  </resource-ref> 
   
   
</web-app>

Ok I think this is it.

From the tomcat docs the references are all relative to java:comp/env and if you look at the JPA examples /jpa/resources-tomcat/META-INF/persistence.xml  it is using:

<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:comp/env/jdbc/TestDB</jta-data-source>

Try changing your persistence.xml to use paths relative to java:comp/env/.

Thanks Jay,

my problem is solved.  You were right with the JNDI tree which has to be relative to java:comp/env/.

My second failure has neen in the ResourceLink tag. The name is automatically relative to java:comp/env/. Thats's why I had to change it from

name="java:comp/env/OnlineZeiterfassungDatasource

to

name="OnlineZeiterfassungDatasource

The global value links to the global resource in the global JNDI context. That is why it has to have the                                   java:comp/env context.

global="java:comp/env/OnlineZeiterfassungDatasource

               <Context docBase="OnlineZeiterfassung2"
                    path="/OnlineZeiterfassung2" reloadable="true"
                    source="org.eclipse.jst.jee.server:OnlineZeiterfassung2">

                    <ResourceLink
                         name="OnlineZeiterfassungDatasource"
                         global="java:comp/env/OnlineZeiterfassungDatasource"
                         type="javax.sql.DataSource" />

               </Context>

Furthermore I had to add the entity transaction to the components.xml

   <transaction:entity-transaction entity-manager="#{entityManager}"/>

Thanks again Jay, I'm really happy to have a running blank project now...
