Java EE using Datasource without search method
I am trying to use Datasource (Database) in my program using JNDI. I made it work partially, but not as if I want it to work. I want to add a JNDI resource, but it doesn't work as expected.
It doesn't work if I use annotation.
@Resource(name="jdbc/crmv1")
DataSource ds;
But it works when I use the search method:
try {
ds = InitialContext.doLookup("jdbc/crmv1");
} catch (NamingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
I want to use annotation. I'm sure I need to set something in the web.xml, but I don't know what. I tried this, but I'm not sure which search engines to use.

Using resource annotation , you can try to use the lookup element instead of the name and use the jndi name that you configured on the app server.
EXAMPLE- If it matches the jndi name "jdbc / crmv1" try @Resource(lookup="dbc/crmv1")
either@Resource(lookup="java:jdbc/crmv1")
The only relationship with web.xml is that you use the deployment descriptor to override the resource mapping specified in the annotation.
