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.
