RE: Question on Struts debugging - one more time
I am not sure what is implied by the below messages:
Using netbeans I am able to
debug servlets
debug jsp's (a little buggy but it works)
debug action classes and form classes.
I am not sure if this all works remotely or not.
logging is always a good idea.

Hi Keith,
Thanks for your reply.
I do use already many of the techniques listed in
your email as well as
log4j.
I do not have any problem catching errors in form
and actions classes.
I do have problem finding errors that come out of
the html tags in JSPs.
If there is a bad mapping and an html:form's action
point to the mapping
with a problem I do not see any errors in any of the
logs. I have modified
my error.jsp in hopes of seeing more but so far
nothing.
If I have better luck with this I will let the group
know.
Developing in Struts would be much faster if there
was a way to diagnose
such problems.

Subject: Re: Question on Struts debugging - one more
time
I've not had better luck. I think it's the way it
is.
Here's how I do it - I'd like to know how others do.
I use hundreds of log messages so I can trace the
flow of my program. I make
the method calls for
logging easy to type - dbmd(a debug msg) or
dbmw(warning message).
I code traces into action classes from the start. to
show the perform method
starting ending so
a dud struts config is found because the Action i
expect to run doesn't log
it's start.
I check for null pointers all over the place log a
warning or throw an
exception for them.
I constantly restart the server (tomcat 3.2.2) to
make weird problems go
away.
Auto class reloading doesn't work properly so - I
restart after every
compile.
I use these 3 methods in jsp's Action classes a
lot, to check the contents
of the session
request - this finds things left in the session by
mistake.
public static void
printSessionAttributeNames(String caller,
HttpSession session) {
public static void
printRequestAttributeNames(String caller,
HttpServletRequest request) {
public static void printRequestParameters(String
caller,
HttpServletRequest request) {
I've attached the code for them, someone may find
them useful - the codes a
bit dodgy old but
it's easy to understand.
I have my own logging code (from old servlet
programming) but I want to use
log4j (one day!) - You
really need to be able to switch trace messages
on/off without re-compiling
classes or restarting
the server.
Only when it's quite reliable do I remove the
messages. Often I just comment
the mesages out in
expectation it will go wrong in future.
All in all a bit primitive compared to some
(non-web) environments I've
worked in. we're in the
early days - things will get easier. We'll get
informative/instructive
messages that tell us what
to do to put it right we'll be able to step thru
our action classes in the
debugger.
Happy bug hunting! - Keith

Sent previously:
I have been using Struts for some time now. My
app's Struts config file
has
almost 50 action mappings so I have been down this
road a time or two.
Many times when adding a new mapping I run into
errors though. For example
the latest on was where the mapping listed an
action class called
something
like UserCreateAction (package removed). But when
I wrote the class itself
I
named it UserAddAction.
Now when I built the app and moved to the Orion
apps server and ran it
when
I get to the JSP that references this action
mapping I get a null
exception.
Typically I do not catch exceptions in a JSP and
the uncaught exceptions
go
to my error JSP where it states that the exception
is null.
So I go into my web.xml file and change the debug
param to 2. I also
changed
detail to 2. (By the way what does detail = 2 do?)
Then I re-ran everything after rebuilding and
re-deploying. The app still
does the same thing.
OK, fine now I go to check the logs. I check the
apps server log where
system outs go. I see no Struts messages except
for the flurry of them at
startup. I look at the log4j error logs and see
nothing. I also looked at
the apps servers application log where I see some
Struts messages but see
nothing about this error.
So my Struts debugging question is this. Are
errors encountered

case sensitive property names ??
Hi,
i had the following case where another process calls an action in my
application with a parameter in url named A.
like: .../actions/process?A=1UNAME=andre
I coded a form bean with a getA/setA pair, but it never gets called. if
I use a in the call to the action, it works.
however, getUNAME() and setUNAME() gets called
from this portion of code in struts 1.0, I can see that
property names are case sensitive:
from PropertyUtils.getPropertyDescriptor(Object bean, String name):
for (int i = 0; i descriptors.length; i++)
{
if (name.equals(descriptors[i].getName()))
return (descriptors[i]);
}
Is this a standard requierments that parameter names must be case
sensitive? even so, how can one populate a bean with single letter
uppercase property names?
Thanks for any inputs

This has to do with the bean spec.
And what you say is right.
If you use all uppercase, it will leave the first letter alone,
otherwise it will uppercase the first letter. And this would include

Re: Bug in BeanUtils.populate()
BeanUtils works correctly in that if you want to set against an index,
you can have the following forms.
Quoted from the bean spec --==
void setter(int index, PropertyType value); // indexed setter
PropertyType getter(int index); // indexed getter
void setter(PropertyType values[]); // array setter
PropertyType[] getter();// array getter
...so it's either setting and getting an entire array collection, or
directly setting and getting objects against an index which can mean
absolutely anything internally to the bean. The BeanUtils class uses
separate code blocks to handle both.
Builds as of a few days ago will accept implementations of
java.util.List as well as the primitive arrays the spec defines.

RE: Bug in BeanUtils.populate()
The spec. supports the following:
setFoo(int index, Object[] array)
However, BeanUtils.populate() does not. The problem is that
BeanUtils.populate() isn't checking if the second parameter is an array
or not, it only checks the first parameter. However, the JavaBean spec.
allows for the second paramter to be of an array type. If you try this,
you will find that it doesn't work in struts1.0 or struts1.0.1 unless
you make the change to the code that I suggested below. If you look at
the code, the bug is very obivious.
