Well I know that there are several Threads about the ClassCast Problem, but nothing helped me realy - except looking that I did not have these errors.
So, I use JBoss 4.04 and started with the TrailBlazer Demo about StatelessSessionBeans. I can start the JSP but I got a ClassCastException during it. I have deployed it to TrailBalzerApplication.ear which contains: | TrailBlazerApplication.ear | application.xml | jboss-app.xml | TrailBlazerEJB.jar | TrailBlazerWeb.war | The application.xml: | <application xmlns="http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="1.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd";> | <display-name>TrailBlazerApplication</display-name> | | <module id="myeclipse.1170763402122"> | <ejb>TrailBlazerEJB.jar</ejb> | </module> | | <module id="myeclipse.1170763401891"> | <web> | <web-uri>TrailBlazerWeb.war</web-uri> | <context-root>TrailBlazerWeb</context-root> | </web> | </module> | </application> | The jboss-app.xml | <?xml version="1.0" encoding="UTF-8"?> | <jboss-app> | <loader-repository> | trailblazerOne:app=ejb3 | </loader-repository> | </jboss-app> | The SessionBean | package trail.slsb; | | import org.jboss.annotation.ejb.LocalBinding; | | import javax.ejb.*; | | @Stateless | @LocalBinding (jndiBinding="EJB3TrailBlazer/slsb/Calculator") | public class StatelessCalculator implements Calculator { | | public double calculate (int start, int end, double growthrate, double saving) { | double tmp = Math.pow(1. + growthrate / 12., 12. * (end - start) + 1); | return saving * 12. * (tmp - 1) / growthrate; | } | | } | Part of the jsp: | <%@ page import="trail.slsb.*, javax.naming.*, java.text.*"%> | | <%! | private Calculator cal = null; | public void jspInit () { | try { | InitialContext ctx = new InitialContext(); | cal = (Calculator) ctx.lookup( | "EJB3Trail/StatelessCalculator/local"); | } catch (Exception e) { | e.printStackTrace (); | } | } | %> | There are no errors during deployment Can anybody please help me?
