I've used struts in the past and have a new project that I'd like to do with
Seam.
I'm not incorporating hibernate due to my inexperience with it and want to know
how to inject a DataSource that's defined in ??-ds.xml in the deploy directory.
There are circumstances where I need to access data in multiple databases from
the same application so I have more than one defined here.
Assume I have the following defined in the ds.xml file
| <local-tx-datasource>
| <jndi-name>myDatasource</jndi-name>
| ....
| </local-tx-datasource>
|
My pojo looks similar to this
| public class LoginAction implements Login {
|
| // What will get my datasource injected here?
| // I've tried countless variations.
| @In or @In(value="myDatasource") or ???
| private DataSource myDatasource;
|
| @In(create=true)
| private User user; // Session scope
|
| public LoginAction() { }
|
| public String challenge() {
| String rtn;
| if(!user.isAuthenticated()) {
| // authentication logic here/ query the database to check
role/access
| // if not authenticated set rtn = "invalid"
| // otherwise store user role/access in user object in session scope
| // User object should reside in session scope for interrogation on
next request.
| }
|
| return rtn;
| }
| }
|
pages.xml looks like this to force authentication on every request
| <pages>
| <page view-id="*" action="#{loginAction.challenge}"/>
| </pages>
|
What @In annotation will work here for myDatasource?
I'm sure this is very simple but please, someone hold my hand. :-)
