             Summary: CLONE - Not possible to get access to the underlying DataSource through WrapperDataSource
                 Key: JBJCA-1065
                 URL: https://issues.jboss.org/browse/JBJCA-1065
             Project: IronJacamar
          Issue Type: Bug
    Affects Versions: 1.0.11.Final
            Reporter: Matthias W
            Assignee: Jesper Pedersen
            Priority: Critical


JNDI lookup for a datasource on EAP 6.0 returns an instance of WrapperDataSource [1] and since it doesn't override JBossWrapper.getWrappedObject() [2] which is in the super class, unwrap() always returns null. 

WrapperDataSource should override getWrappedObject() as stated in the javadoc to return the underlying datasource.

With the current implementation, the following code always throws exception: 
{code:java} 
    Context ctx = new InitialContext();
                DataSource ds = (DataSource)ctx.lookup("jboss/datasources/ExampleDS");
                OracleDataSource unwrapped = null;
               
                if (ds instanceof WrapperDataSource) {
                        WrapperDataSource wrapper = (WrapperDataSource) ds;
                        try {
                                unwrapped = wrapper.unwrap(OracleDataSource.class);
                        } catch (SQLException e) {
                                e.printStackTrace();
                        }
                }
{code}
