Something strange with @Producer

flying00cn Jun 12, 2011 11:49 PM

My project need a JDBCDAO util.
so I write below:
the qualifier:
@Qualifier
@Target({ElementType.METHOD, ElementType.FIELD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface JDBCDao {
    @Nonbinding public String value() default "";
}

the Producer :
public class DaoProductor {
    @Produces @JDBCDao
    public BaseJdbcDao getJdbcDao(InjectionPoint ip){
        String JNDIName = ip.getAnnotated().getAnnotation(JDBCDao.class).value();
        if( JNDIName.compareTo("")==0)
            return null;
        try{
            DataSource dataSource = (javax.sql.DataSource) new javax.naming.InitialContext().lookup(JNDIName);
            if( dataSource == null )
                return null;
            return new BaseJdbcDao(dataSource);
        }catch(Exception ex){
            ex.printStackTrace();
            return null;
        }
    }
}
and at the same project the test Code:

@Inject @JDBCDao("jdbc/pool") BaseJdbcDao dao;

works well

SO I package the Qualifier,Produces,and daoutil into a jar file,
my real project import the jar
when I use:

@Inject @JDBCDao("jdbc/pool") BaseJdbcDao dao;

get WELD_001408 error like this:

Exception while loading the app : WELD-001408 Unsatisfied dependencies for type [BaseJdbcDao] with qualifiers [@JDBCDao] at injection point [[field] @JDBCDao @Inject @Exact com.ccb.dl.common.test.JdbcTest.dao]
