I'm having a similiar problem.
I took over an EJB app from another programmer who is no longer around, and one
of the first things I'm trying to do is add a simple method to a class called
"Department Model":
public class DepartmentModel implements Serializable
{
...
public void printSomething() { System.out.println("something...........");
return; }
...
}
In a jsp that instantiates a DepartmentModel class, I try to test this new
method:
...
dept.printSomething();
...
And I get the following exception trace:
16:44:39,396 ERROR [Engine] ApplicationDispatcher[] Servlet.service() for
servlet jsp threw exception
java.lang.NoSuchMethodError:
com.icshealth.model.DepartmentModel.printSomething()V

etc...
PeterJ, I followed your suggestion to verbosely output the classloader details
and everything looks like i'd expect:
...
[Loaded com.icshealth.ejb.entity.DepartmentBean]
[Loaded com.icshealth.model.DepartmentModel]
[Loaded com.icshealth.ejb.entity.DepartmentHome]
[Loaded com.icshealth.ejb.entity.Department]
...
I went as far as to download the .ear file, extract it with WinRAR and
de-obfusticate DepartmentModel.class with CavaJ, and the "printSomething()"
method was there just as I had added it.
I double-checked that there were no other .ear, .jar or .war files on the
server that may have old versions of DepartmentModel rolled in and couldn't
find anything.
We're using 3.2.5. Old, I know - and we will upgrade at some point - but right
now I'm afraid that's not an option.
I am very confused. Any suggestions?
Thank you.
-Robin
