Error while accessing bean created from servlet

Question

Hi there
I have a jsp page form home.jsp where i am collecting user name and password and then directing to a LoginServlet.Here if the user is validated then i create a accMasterBean and store it in Session object which i create here and then redirect to profile.jsp
In the profile.jsp page i am using bean as follows:--
<jsp:useBean id="accMasterBean" scope="session" class="AccountMaster">
<jsp:setProperty name="accMasterBean" property="*"/>
</jsp:useBean>
i am fetching the properties of this bean in profile.jsp itself and try to display as shown below:---
<%=accMasterBean.getAccountNumber() %>
where accountNumber is a property defined inside AccountMaster class
but it gives an error as follows :---
<input type="text" name="emailAddress" value="Exception generated ---javax.servlet.ServletException: Exception thrown on line '205' from page 'D:\\Program Files\\Allaire\\JRun\\servers\\default\\emtech2\\jsp\\members\\profile.jsp'.
Plz note if remove the above line of fetching the property of bean in profile.jsp page then there is no error
Hoping to get a reply soon
Thanking u
Mumtaz
