appserv-core/src/java/com/sun/enterprise/util/InvocationManagerImpl.java
from which the exception is thrown, defines a "frames" ThreadLocal
which stores a thread's current stack of component invocations as an
ArrayList.
During a preInvoke(), a ComponentInvocation is pushed onto the current
thread's stack (unrelated code removed):
public void preInvoke(ComponentInvocation inv) throws InvocationException
{
// Get this thread's ArrayList
ArrayList v = (ArrayList) frames.get();
// push this invocation on the stack
v.add(inv);
}
and during a postInvoke(), it is removed from the stack:
public void postInvoke(ComponentInvocation inv) throws InvocationException
{
// Get this thread's ArrayList
ArrayList v = (ArrayList) frames.get();
int size = v.size();
if (size == 0)
throw new InvocationException();
finally {
// pop the stack
v.remove(size - 1);
}
}
Therefore, the assertion is made that during a postInvoke(), the stack
must not be empty. For some reason, it is empty in your case, which is
why postInvoke() throws this InvocationException (which really
should have an error message):
int size = v.size();
if (size == 0)
throw new InvocationException();
There could be 2 reasone why the stack is empty in your case: either
preInvoke() was not called, or postInvoke() was called twice in a
row.
Fortunately, J2EEInstanceListener prints out the events it receives
(which trigger a preInvoke() or a postInvoke()):
public void instanceEvent(InstanceEvent event) {
String eventType = event.getType();
if(_logger.isLoggable(Level.FINEST)) {
_logger.log(Level.FINEST,"*** InstanceEvent: " + eventType);
}
Can you set your web-container logging to FINEST and grep for
InstanceEvent in your log?
