What's the magic in StatelessSessionContainer?? please, help
Hi
When i try to deploy my UserData bean (Stateless), i get the following stack:
15:43:12,080 DEBUG [StatelessSessionContainer] Mapping remove
15:43:12,081 DEBUG [StatelessSessionContainer] Mapping remove

... but if i define the UserData bean to Stateful, then it deploys correctly.
The line in StatelessSessionContainer.setupHomeMapping is next:
if (homeInterface != null)
{
Method[] m = homeInterface.getMethods();
for (int i = 0; i < m.length; i++)
{
// Implemented by container
if (debug)
log.debug("Mapping "+m.getName());
map.put(m, getClass().getMethod(m.getName()+"Home", m.getParameterTypes())); // this is line 457
}
}
,but the code in StatefulSessionContainer.setupHomeMapping is also very same kind:
try {
// Implemented by container
if (isEJB1x == false && m.getName().startsWith("create"))
map.put(m, getClass().getMethod("createHome", new Class[]
{ Invocation.class }));
else
map.put(m, getClass().getMethod(m.getName()+"Home", new Class[]
{ Invocation.class }));
}
catch (NoSuchMethodException e)
{
if (infoEnabled)
log.info(m.getName() + " in bean has not been mapped");
}
.. so what's the problem???, and why it trys to get method createHome?? (if i read code correctly..)
