Does this only occur when you return a null or 0 buffer size?

My guess is that it's a bug in the StreamResult or the result handler.
It probably evaluates "${bufferSize}" and deduces that the property
doesn't exist (because it's null/0) and uses it as a literal string
value instead. That's just a guess.

Is it really valid to return a zero length stream result? I would
instead return a http status result with 404 / NullResult for the error
case (ie. just headers, no content).

What I actually return is a DefaultHttpHeaders with a 404 set.
getImage() returns an empty (not null) inputstream since there's no
content for the body.

I'll do some debugging when I get time and see where it's failing. It
certainly seems to be StreamResult that has the issue.

Thanks

Mike

You may need to return a different result type for the error case
(HttpHeaderResult or NullResult) so it only attempts to set the headers
though.

Thanks mate. I'll give that a try tomorrow.

hi,

The issue:

1. We have implemented a wizard application (with 4 Steps) with action
variables maintained in session.
2. The pages also have train in the top, i.e. from any step he can jump to
any of the other steps.
3. The Step1, 2,3,4 (mentioned above ) are interdependent i.e. based on
selection in step 1 step 2 is influenced; based on selection in step 2 step
3 is influenced and so on

4. Now: In step 1 user entered wrong value (10000 say) for integer field
which is not allowed by validations. He clicks on save and page throws
validation exceptions (Expected)
5. He then clicks on train 2 i.e. he is jumping to page 2
6. The page is being displayed based on the incorrect value (100000) which
was rejected by validation of first page. If i use the train again and go
back to the 1st step i still see 10000 there

7. Question: When validation error happens aren't the action variable values
restored to the previous once?(say the prev once is 10 or 0 i think they
should be reset to 10 or 0 when system throws error at 10000). Is there any
way in which this can happen?

is there any way to call an interceptor/ execute a method after the JSP is
rendered? so that i can restore variables back incase of validation errors.

Please help.

cheers,
ravi

Subversion shows the link and page were added on 27 August 2007.

Pierre,
about the Tiles part, I suggest to ask this question at Tiles Users

Hi,
I’m new in Struts 2 and I want to do some configuration (log4j, DataBase,…)
in the loading of my application. In Struts 1 I use an implementation of
PlugIn and do these configurations in init() method. Could you please help
me?
Best Regards,

You can use a ServletContextListener:
http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletContextListener.html
Obviously you have to configure it in web.xml:
http://www.java-tips.org/java-ee-tips/java-servlet/how-to-work-with-servletcontextlistener.html

As there are no struts tags you should post this to the displaytag list
for a better response;

Subject: What is the best way to handle cancel, Update, Back Buttons in
Struts2


Hello Everyone

I know this might be very easy for you guys but it is being difficult
for
me.:working:

I am developing an updateUser.jsp page and it has three buttons those
are:
Update, Cancel, Back
Now if I press update it should invoke the updateUser action mapping
also I
need to do the validation first before I do something else. If Cancel is
pressed the previous values which was already there in the field should
be
displayed and when I press Back button it should not do anything just go
to
my userList page.

So I am not able to understand how should I handle the struts.xml and
the
jsp code. I know I can use built in validator framework and by defining
the
validation.xml file for those fields but whenever I cancel or go Back
the
error message appears in the page so I don't know how should I handle
this
thing.

Please tell me the best way from your experience how should I handle
this
kind of situation.

Thanks for the help in advance!

Hi,

I have one form with multiple textfields, and I want to one of that
textfield be optional for user, i.e., he doesn't need to enter information

How can I enable this but without getting this error ?

submit error my occur if he don't choose anything from combox box.
