Jakarta EE ResourceAdapter Arayüzünü tanımlarken pek çok bilgi XML içindedir. XML içindeki tag'lerden bazılarını @Connector Anotasyonu ile koda almak mümkün. 

displayName Alanı

Örnek

src/main/resources/META-INF/ra.xml dosyasında şöyle olsun

<connector ...> 
  <description></description>
  <display-name>MyResourceAdapter</display-name>
  <vendor-name>Java EE Tutorial</vendor-name>
  <eis-type></eis-type>
  <resourceadapter-version></resourceadapter-version>                                  
  <resourceadapter>
  
    <resourceadapter-class>
      com.foo.MyResourceAdapter
     </resourceadapter-class>

@Connector(
  displayName = "MyResourceAdapter",
  vendorName = "Java EE Tutorial",
  version = "7.0"
)
public class TrafficResourceAdapter implements ResourceAdapter, Serializable {
  ...
}
