[jboss-user] [EJB 3.0] - ClassCastException on JNDI lookup

[morisona]

There is reason to beieve that this problem is easy (http://jira.jboss.com/jira/browse/EJBTHREE-456), but I have searched the forum and can not find exactly the same situation.
The easiest way to reproduce it is to take the calcualtor.jsp from the EJB3Trail, and put it in a seperate war along with trail.slsb.Calculator.class. I then get

  | 20:12:40,859 ERROR [STDERR] java.lang.ClassCastException: $Proxy136
  | 20:12:48,437 ERROR [STDERR]     at org.apache.jsp.calculator_jsp.jspInit(calculator_jsp.java:19)
  | 20:12:48,437 ERROR [STDERR]     at org.apache.jasper.runtime.HttpJspBase.init(HttpJspBase.java:78)
  | 20:12:48,437 ERROR [STDERR]     at org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:155)
  | 
The relevent bit of code in the jsp is:


  |       InitialContext ctx = new InitialContext();
  |       cal = (Calculator) ctx.lookup(
  |                   "EJB3Trail/StatelessCalculator/local");
  | 
On the JMX JNDI screen I have:

  |  +- EJB3Trail (class: org.jnp.interfaces.NamingContext)
  |                ........
  |   |   +- StatelessCalculator (class: org.jnp.interfaces.NamingContext)
  |   |   |   +- local (proxy: $Proxy136 implements interface trail.slsb.Calculator,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
  | 
Any help and I would be infinitely greatful.
