How do you configure a JNDI datasource in Grails 3

Grails 3 (3.0.9) app is failing to start on a TC server where another 2 Grails 2 apps using each its JNDI datasource are running fine.

It seems that replicating my Grails 2 JNDI settings in Grails 3 is not working (I left everything else default and specified driverClassName, dbCreate and jndiName for my prod datasource settings).

The application has no problem connecting to the MySQL database straight through JDBC. Only JNDI makes it crash with the below exception (fragment)...

回答1:

your correct above didn't work. I followed below steps, its working now for me.

tomcat context.xml file defined like this:
```
Resource name="grailsDB"
```

application.yml added this production datasource.

production:
    dataSource:
        dbCreate: update
        jndiName: java:comp/env/grailsDB

created the grails-app/conf/DataSource.groovy file, based on https://grails.github.io/grails-doc/3.0.x/ref/Plug-ins/dataSource.html document.
```
dataSource {
    jndiName = "java:comp/env/grailsDB"
}
```
created the war file using grails war command.
deployed in tomcat and tested it by adding deleting the sample data.

Here is software versions I tested with.

APPLICATION STATUS
    Environment: production
    App profile: web
    App version: 0.1
    Grails version: 3.0.3
    Groovy version: 2.4.3
    JVM version: 1.8.0_65

Hope this helps.

thanks -SR

In application.yml I replaced url with this value,it work for me. you can try the same.

 production:
        dataSource:
            dbCreate: update            
            jndiName: java:comp/env/jdbc/dbjndiname
