java - How do I define only scheduler attribues in the deploymnet descriptor, not the whole bean? -

-

i have following bean: 

@stateless public class newsessionbean {      public void myjob() {         system.out.println("run");     }  }

and have myjob running every 10 seconds, have deployment descriptor:

<ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee"   version = "3.1"   xmlns:xsi = "http://www.w3.org/2001/xmlschema-instance"   xsi:schemalocation = "http://java.sun.com/xml/ns/javaee      http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd">   <enterprise-beans>     <session>       <ejb-name>newsessionbean</ejb-name>       <ejb-class>org.test.newsessionbean</ejb-class>       <session-type>stateless</session-type>       <timer>         <schedule>           <second>*/10</second>           <minute>*</minute>           <hour>*</hour>           <month>*</month>           <year>*</year>         </schedule>         <timeout-method>           <method-name>myjob</method-name>        </timeout-method>      </timer>    </session>  </enterprise-beans> </ejb-jar>

and works.

but declare timer in deployment descriptor, not whole bean can declare using annotations , parametrize schedule.

if remove ejb-class or session-type application won't load because dd missing information.

is there anyway can override information scheduler only?

edit: move set parameters on @schedule annotation deployment descriptor can change values without needing recompile/redeploy
