Hi Sir,
Thanks for help. I appreciate your attention. See ya!
This is my ejb-jar.xml file here i do have all the classes means
interface
name.
<ejb-jar id="ejb-jar_1" xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd"; version="2.1">
<description>Example of a session bean</description>
<display-name>MyTimeBeanEJBName</display-name>
<enterprise-beans>
<session id="Session_MyTime">
<ejb-name>My.DemoEJB</ejb-name>
<home>My.DemoHome</home>
<remote>My.DemoInter</remote>
<ejb-class>My.DemoBean</ejb-class>
<session-type>Stateful</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>
When I try to execute my client , I receive this error message:
java.lang.ClassCastException.
Could anyone tell me what I’m doing wrong? Thanks a lot. Looking forward to
hearing from you.
