communicate one ejb bean to another ejb bean

[thomas davis]

Enterprise Beans are building blocks that can be used alone or with other enterprise beans to build complete
How to communicate one ejb bean to another ejb bean?
Can I call one ejb bean in another ?

[Pradeep bhatt]

Yes, you can call on EJB from another. You will use the same lookup code to call an ejb from another.

[thomas davis]

Could you please send me the code snippet,I mean how to call it ?
Is it possible to call another stateless or stateful or entity bean from another bean ?

[Pradeep bhatt]

   Context initCtx = new InitialContext();
      Context env = (Context)initCtx.lookup("java:comp/env");
      String homeName = (String)env.lookup("ejb10-properties/Product");
      targetHome = (ejbs.ProductHome)lookupTargetHome(homeName, 
         ejbs.ProductHome.class);
  

[Lasse Koskela]

Context initCtx = new InitialContext();
Context env = (Context)initCtx.lookup("java:comp/env");
String homeName = (String)env.lookup("ejb10-properties/Product");
targetHome = (ejbs.ProductHome)lookupTargetHome(homeName, ejbs.ProductHome.class);

<hr></blockquote>
Pradeep, why not use ejb-ref if you need to avoid hardcoding the JNDI name of the other bean?

// lookup code
Context initCtx = new InitialContext();
Context env = (Context)initCtx.lookup("java:comp/env");
ProductHome home = (ProductHome) env.lookup("ejb/Product");
// ejb-jar.xml
<ejb-local-ref>
    <ejb-ref-name>ejb/Product</ejb-ref-name>
    <ejb-ref-type>Entity</ejb-ref-type>
    <local-home>ejbs.ProductHome</local-home>
    <local>ejbs.ProductBean</local>
</ejb-local-ref>
