STEPS I FOLLOWED
I have created a small bank transaction application using EJB and Struts
A)BankEJB
1)Account.java - > Getters and setters

2)Bank.java->Interface(2 Methods) -> i) transfermoney ii) validateaccount

3)BankBean.java - > is the bean wer actual bussiness logic for above 2 methods resides

4)BankHome.java -> create Ejb

5)DatabaseUtil.java - > database connection logic resides here.

6)ejb-jar.xml - >

    <ejb-jar>
   <description>My First EJB</description>
   <enterprise-beans>
      <session>
         <ejb-name>BankEJB</ejb-name>
         <home>com.myejb.BankHome</home>
         <remote>com.myejb.Bank</remote>
         <ejb-class>com.myejb.BankBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Bean</transaction-type>
      </session>
   </enterprise-beans>
</ejb-jar>

7)jboss.xml - >

   <jboss>
	<enterprise-beans>
		<session>
			<ejb-name>BankEJB</ejb-name>
			<jndi-name>BankObject</jndi-name>
		</session>
	</enterprise-beans>
</jboss>

then created a jar for this ejb application and then includede in struts library

B)BankSTRUTS
1)LoginAction -> bussiness logic for action taken on click of login

2)TransferAction -> bussiness logic for action taken on click of transfer

3)Home.jsp ->
