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 - >
Code :
<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 - >
Code :
<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 ->
Code :
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

Re: Struts Application, Complies perfectly but error at run time
Hello there,
You need to have a look in your MessageResources.properties file again.
Make sure that the property Login.userAccountNumber actually exists. Looking at your post above it appears it does not, you have login.UserACNumber instead.
// Json
Re: Struts Application, Complies perfectly but error at run time
Hey hi
I did check it out and made changes accordingly but still its not working.
MEssageResources.properties
login.userAccountNumber=User Account Number
login.userPassword=User Password
login.Log=Login
And accordingly made changes in Login.jsp
<html:form action="/GoLoginAction" method="post" onsubmit="return validateLoginDynaForm(this);">
<P>
<bean:message key="login.userAccountNumber"/><html:text property="userAccountNumber"/><BR>
<bean:message key="login.userPassword" /><html:password property="userPassword"/><BR>
<html:submit ><bean:message key="login.Log"/></html:submit>
</P>
</html:form>
