"No getter method for property foo of bean bar" --really?
Hi,
I'm gnashing my teeth over the following, and solicit help.
I'm involved in moving an older (Struts 1.2, JDK 1.4, Tomcat 5.0) app,
currently running in production under Linux, to Windows (don't ask).
Simply by copying the whole web app tree over (and adjusting Tomcat's
server.xml on the Windows side), I get large areas of the app's
functionality working just fine.
However hitting on one particular JSP, I run into this...
2008-02-21 08:43:44 ApplicationDispatcher[/jsp] Servlet.service() for
servlet jsp threw exception
javax.servlet.jsp.JspException: No getter method for property
timeslotManager.reservationTimeslot.startDateString of bean
reservationListForm
...where the offending code in the JSP appears to be this:
<bean:write name="reservationListForm"
property="timeslotManager.reservationTimeslot.startDateString" />
1. Now I know what you're thinking--capitalization problem--but it's not
that, honest (I just checked for the hundredth time).
ReservationListForm has getTimeslotManager(), ReservationTimeslotManager
has getReservationTimeslot(), and ReservationTimeslot has
getStartDateString().
2. The app is running without these errors under Linux.
3. If I run the app under Eclipse's debugger and set a breakpoint just
before the bean:write, I can see 'reservationListForm' sitting in the
session and navigate through to the ReservationTimeSlot object. All the
expected objects are sitting there, everything looks just right.
4. If I insert a scriptlet into the JSP immediately before the
bean:write, I can walk the object graph without error, and get back the
expected values from the method calls:
<%
ReservationListForm rlf = (ReservationListForm)
session.getAttribute("reservationListForm");
ReservationTimeslotManager rtm = rlf.getTimeslotManager();
ReservationTimeslot rt = rtm.getReservationTimeslot();
String startDateString = rt.getStartDateString();
...
%>
5. Can't access any other properties of 'reservationTimeslot' either.
And if I try shortening the chain of nested properties...
<bean:write name="reservationListForm" property="timeslotManager"/>
...runs without error, but...
<bean:write name="reservationListForm"
property="timeslotManager.reservationTimeslot"/>
...again brings the "No getter method..." error.
6. Same behavior if I move the app to OS X.
This is all amusing, of course, but I'd like to move on to other things.
Does it ring any bells? Any suggestions about other things I might try
looking at?
Thanks, Mark

I see the same behavior under java 5 on OS X.

Thanks for the offer and for the suggestions.

Dunno about you, but "some sub-version" doesn't exactly fill me with comfort.

If you say so.
If it were me I'd try running under a different JVM first, because it's easy,
it's still an unknown (to me), etc. It surprises me a little that the weird
behavior is on both Win and OSX. If you can isolate the issue to a minimal
testcase and host it somewhere I can look at it under OSX.

The VM that I've used is (some sub-version of) 1.4.2 in all cases.
The libraries on the app's classpath are precisely identical because the
apps are precisely identical. The libraries on the container's classpath are
precisely identical.

Have you tested under a different JVM version? Are the libraries on the
classpath (both your apps and Tomcat's) precisely identical across
environments?
