Cannot find bean error

[Anoop]

Hi,

I am trying to loop through an ArrayList returnd by a bean inside


Name in the Iterator tag specifies a bean set in request scope in my
ActionBean, getter on which will return an ArrayList. I am trying to read
the bean returned by the ArrayList inside the Iterator tag. There is an
exception thrown:

javax.servlet.ServletException: Cannot find bean EMTTaskDetail in scope
null

I tried specifying all the possible scopes, session and request but it still
throw this exception

The scriptlet looks something like this:



  

 ...

getTaskDetails() on the bean set in the request scope with key
"timesheetDetails" returns an ArrayList of EMTTaskDetail objects.

Thanks for your help.

Thanks & Regards,
Anoop.

Re: Problem when writing bean value into textbox

[Eddie Bush]

Well, you can't "nest" tags the way your first example shows - it's 
invalid XML, I believe.  Your second example should work, but I have to 
question what you're calling "function" and "functionName".  The name 
attribute should be the name of a bean - in request scope (since you've 
stated that's where it is) - and property should only be the name of the 
property you wish to retrieve the value of -- not the name of the accessor.

Ex:  class Foo - has attribue bar (and accessors getBar() and 
setBar(String bar)) - instance in request is foo:



If that doesn't help, maybe you could give a broader overview of what 
you're trying to actually do :-)  My guess is that you want to specify 
default values for a form.  There are a couple of other ways you can do 
that:

- use a Dyna*Form and specify the initial (probably String) value
- preface the call to the page with an action that will populate the 
form and then forward to your JSP

Repost if that doesn't help - explain your scenario a little better 
though, please :-)

[Steve Vanspall]

if this is in a  tag, which it would need to be

then just use 

this will automatically populate the bean providing there is a
getFunctionName() method in your form

Re: Specifying button-specific actions in a form

[K Br]

DispatchAction works fine. Thanks.

However I need to submit different ActionForms
with different subactions in

 
   
   
   ...

Since DispatchAction multiplexes different
subactions using the same action mapping
entry, it will use the same ActionForm.

The other way is to define distinct action mappings 
for different subactions (add, delete, ...) and
specify different form beans for each entry in
struts-config.

I prefer to use DIspatchAction, as I think its neater.
Is there a way for me to tell DispatchAction to
use different forms beans for different methods?

Re: Any Idea about Paging Logic

[Brian Alexander Lee]

I looked at the display tag library:
http://edhill.its.uiowa.edu/display/

Did I majorly screw something up or is this tag not thread safe? I noticed
when I sorted a page of data, the next user to hit the page got that default
sort. It was quite infuriating. I hope it was just me.

RE: Session management for cached resources

Im running 1.1, so in your case, running 1.0 you would need to make changes
in the ActionServlet, as afaik the RequestProcessor is a 1.1 thing.

That sounds pretty close to what I want to do.  Which version of Struts
are you running?  I'm still on 1.0 right now.

Something else I was considering was to use a naming convention like
"context.name", and then have a utility method that would iterate
through the session and remove "mymodule.*".  Not quite as elegant as
your solution though. =)

[NESTED TAGS] Questions regarding nested:iterate and indexid....

[Jeff_Mychasiw]

I am using 1.1b1
Summary: I cannot make use of the indexId reference in side a java method, unless I 
specify an id="XX" attribute.
The funny thing is that the id attribute can be named anything.


I have been coding my list in this manner for some time without problems.
I am using the logic:iterate with the indexid="counter" passed into a java function 
that swaps the row style.
The toggleRow method assumes that the counter reference is an Integer object.

 

 
 
 
 

I would like to use the nested library and near as I can I should be able to use this:
 

  



This will result in a compile error: Undefined variable: counter

I get the code to work by adding an id attribute with any value in it.


  


This code works as the above code I started with.

Is this a bug in 1.1b1 that has been fixed in 1.1b2 ?

RE: enforcing max upload file size - before its too late!

[James Higginbotham]

Realistically, something is needed in the core web server (Apache, or in
the lower layers of the socket listeners in the servlet spec) to stop
incoming POST requests that exceed a certain amount. With this code
(which I've used before as well), you can't stop the upload and close
the connection, you have to accept all the bytes and then process once
control is given to your servlet/JSP/Struts action. By that time, the
user may have tried to take down your server by pushing many threads
with large files to fill up your drive space (or at least
unintentionally caused you grief). 

Anyone know of a more aggressive method of handling this without getting
rid of uploads all together?

Re: enforcing max upload file size - before its too late!

[Thomas Eichberger]

Hi,

here is my piece of source code for that problem:


stream = file.getInputStream();

zipFile = new File( user.path, user.kurzname + "-upload.zip" );
bos = new BufferedOutputStream( new FileOutputStream( zipFile ) );

int bytesRead = 0;
int count = 0;
byte[] buffer = new byte[ 8192 ];
while ( ( bytesRead = stream.read( buffer, 0, 8192 ) ) != -1 )
{
bos.write(buffer, 0, bytesRead);
count += bytesRead;

 if ( count > 200 ) // THIS IS THE MAXIMUM SIZE
 {
 errors.add(ActionErrors.GLOBAL_ERROR,
 new ActionError( "error.upload.file" ) );
 return mapping.findForward( "failure" );
 }
 }


And I have a finally block surrounding this where I close all streams :-)

Using CheckLogin tag from within tiles

[Alan P Sexton]

I am switching from plain JSP to using tiles. I was using a CheckLogin
tag on my JSP based on the one in the example for struts. This checks if
there is a valid user in the session and, if not, creates an ActionError
indicating that the session has timed out and forwards to logon.

Now I have a simpleLayout.jsp similar to that in the tiles section of
the Chuck Cavaness's online book draft: I insert a header, a body and a
footer in the simpleLayout for my normal pages.

Now I have a problem with the CheckLogin tag:

- If I put it in the body insert, then when the login check fails
  (because of session timeout) it throws an exception saying that it
  couldn't forward because the output was already committed (I presume
  that the preceding tiles do a flush).

- If I put it at the top of the simpleLayout.jsp (which I thought would
  be before anything was flushed) then it detects the error (and creates
  the correct ActionError) but the forward to the logon page doesn't
  work (the current page is displayed) and the page skip of the
  CheckLogin tag doesn't work.

Can anyone explain to me what is going on and how to fix it?

Well, I managed to get the tabs to work. However, I am not to sure if it was a

Specifying button-specific actions in a form

[K Br]

I have a form with three commands (add, delete and logout). It appears to me that I 
must forward them
to a single action and conveying the specific
operation using a property as in:

 
 //...
 
 
 
 

I would like to make the JSP more readable by
specifying distinct actions to distinct buttons:
   Add -> /performAdd.do
   Delete -> /performDelete.do
   Logout -> /logout.do

(these actions may be implemented by the same
Action class, but that's hidden from the JSP 
author).

Is there a way to do this?
 
Tx,

can you clarify? I thought you are passing the full path

RE: [OT] Should I use a persistence layer?

[Cliff Rowley]

Yeah, I'm totally for it - I need some time to spend tidying up and
documenting what I've done (I did reply to Matt personally), but then
I'm happy to feed it to the lions.  As I said to Matt, it's just a brain
dump and needs a shed load of work.  I'm hoping to get some time after
Tuesday.

In the meantime, is your toy available for scrutiny?

Subject: Should I use a persistence layer?


Hi,

For an web application, is there a way for a user to


>>>paginate through
>>>
>>>
(similar to google) a lot of data across multiple browser windows.

The usual way of paginating with session scope works fine. However, 
if a user has 2 windows open on the same application. When he/she
queries on one,
then queries on another, and then comes back to the first
window and click
"Next", he/she will get bad results.

Does this lead to EJB or any other persistence layers?

Thanks,


Dean Chen

No Context Configured to Process this request

[Divakar Satyanarayan]

Hi ,

  I have a pop up window that opens when the user clicks on a button. I have
made use of the action parameter"/popUp" to be sent as the URL. I have
defined a forward for the action in my struts-config.xml.

 Below is my content of my struts-config.













  

 This is the code where I am passing the action as a parameter to open new
window



 but when I click on the button I get the following error 

  HTTP 500 - No context configured to process this request. What is it that
I doing wrong here ?

 Please do give in ur suggestion.

Thanks in Advance,
Divakar

Hi,

i would like to underline that. My own (toy) project is also based on
hibernate and i spend much time doing very basic things, reinventing the
wheel. May be there are many of us out there all doing the same who could at
least act as a sparring partner.

Is there anyway that you could post some more info about your thoughts,
suggestions, ideas, etc about "Huts".  Maybe even post a link to a
zip/tar with the current work you have? I would be very interested in
this and helping out with the project as I am using a combination of
Struts and Hibernate both at work and home and find them BOTH very useful!
