As we realize so far, a browser window may send
request A to a server. The server starts thread A
to handle it. Before the thread A returns, the same
window may send request B to the server, therefore
the server creates thread B to handle it.

Assuming thread B finishes earlier than thread A, we
could have the following possibilities:

1) The server waits thread A to finish and send response A
and then send response B. (I do not believe this is the
Tomcat implementation, correct?)

2) The server sends response B back to the browser
window and the browser window displays it and ignores
response A after it.

 3) The browser displays response B and then displays
response A.

What I can see is that thread B is the trouble maker. But it
is possible when end users click more than one buttons.
In Swing, such problems are resolved by Single Thread
Model. Should we follow Single Thread Model at
servers? Are there any other practical solutions to it out
there?

AW: Tiles problem?

2003-09-10 Thread Roland Berger

Well, the tile which is referenced with the attribute billingAddress is
found. The problem starts latter. Again the hole story  in short:

- The code is working with sturts 1.1 beta xy? Sorry I can not find out
which beta it was. Now I use 1.1 final.

- My tiles definitions are in a seprate file -- tiles-defs.xml
- I hava a master layout jsp page where usually only the body part is
changing.
- One of the body tiles is called: let's say 'tile1' referencing a jsp page:
let's say page1
- I have another tile (tile2) referencing page2 which is inserted in tile1

The structure of the pages is as follows (Comments start with ***):

page1 (tile1):

html:form action=/RegisterAddressAction.do
*** RegisterAddressAction.do works with an actionformbean ( lets call it
AFB1 which isdefined in struts-config.xml) which has a getter to get orderFB
nested:nest property=orderFB
  nested:text property=billingEqualShippingAddress /
/nested:nest
*** -- Cedric told me I can not use tiles in a nested context. -- so I
close the nested context before tiles:insert
tiles:insert  attribute=tile2/
/html:form

page2 (tile2):

*** because the information I want to display is in
AFB1--orderFB--orderBean I start to nest again in tile2

 nested:nest property=orderFB
 nested:nest property=orderBean

*** here the problem starts. the property invoiceCompany can not be
displayed because it seems that the AFB1, orderFB or orderBean are not found
in any scope. The error which is displayed here is: [ServletException
in:/WEB-INF/pages/JSPPage2.jsp] Cannot find bean in any scope'

  nested:text property=invoiceCompany size=50 maxlength=50/
  /nested:nest
  /nested:nest


Again, this code is working with beta versions of struts 1.1.

Any hints?

Thank you
Roland

you could pass it along with the tile.

  tiles:insert attribute=billingAddress 
tiles:put name=billing beanName=.../

or re-access it from whichever scope it was put in.

Hi all

I have JSP code which used to work with older struts versions (1.1 beta xy).
Now I use struts 1.1 stable release.

I have  two jsp pages. I want to nest JSPPage2 into JSPPage1 with
tiles:insert ( see JSPCode ). All I get is [ServletException
in:/WEB-INF/pages/JSPPage2.jsp] Cannot find bean in any scope'
With debugging I have found out that JSP Page 2 losses the parent context (I
mean the bean which is assosiated to the /RegisterAddressAction.do action in
struts-config.xml). How can I handle over the parent context to the nested
JSPPage2 tile?


Thanks for any help

Indexed Properties problem / what version of struts is compatible ?

This example from jakarta is it available with 1.02 version of struts ?

The simplest demonstration of using indexed properties in Struts can be

public String getStringIndexed(int index) { return (strAry[index]); }
public void setStringIndexed(int index, String value)
{ strAry[index] = value; }
}
First note the two methods in the StringBean class, getStringIndexed() and
setStringIndexed(). Note that the get method takes an int and the
set method takes an int and String. The Beanutils package and Struts
recognizes this arrangement of signatures as an indexed property, in this
case with the property name stringIndexed.

Note the property value of stringIndexed[1]. This is intended to reference
the indexed property stringIndexed, and the 1st (zero-based) entry of
whatever array or collection which the indexed property represents.

As you might be able to guess, when this page is executed, it will print
just the string String 1, which is the corresponding array entry at that
index value.

This is a simple demonstration of what indexed properties can provide.

If I given some entires like 31/12/02, it throws an Exception or it

Question about ActionForm

Hi all,

I have a J2EE application using struts and JSP to build the view to my 
model.
I have a session facade bean which returns me ValueObject of my beans.
For instance I have a GroupValue object which represents data of my local 
GroupBean.

I made a ActionForm as follows (GroupForm.java):

import nl.xbase.group.value.GroupValue;
import nl.xbase.management.struts.action.BaseForm;

/**
 * @author harm
 * 
 * @struts.form
 *  name = groupForm
 */
public class GroupForm extends BaseForm {
private GroupValue groupValue = new GroupValue();
 
/**
 * @return
 */
public GroupValue getGroupValue() {
return groupValue;
}

/**
 * @param value
 */
public void setGroupValue(GroupValue value) {
groupValue = value;
}

}


I also have an Action which displays all groups. I put them in a 
Collection and return the collection to the JSP.
I use the iterator tag to iterate through those groups as follows:

logic:iterate id=groupValue name=groups property=groups
html:form action=/editgroup.do method=post
html:hidden property=groupId name=groupValue/
bean:write name=groupValue property=groupName/
/html:submit
/html:form
/logic:iterate

As you can see I call /editgroup.do in this form, which expects an 
GroupForm as input.
Therefore I need to set the property groupValue.groupId of the GroupForm.
But I don't know how to do this. The only way I can think of is to include 
a private String id in the GroupForm. But this seems to be redunnant.

Is there some other way? Or what is a good way to tackle this problem?

Many Thanks,

RE: What's the best strategy to handle this kind of thread issues?

My undertsanding was that the browser will only show the response to the the
second of the requests - forgetting about the first. The server of course
hasnt forgetten about it and keeps processing (one hopes). Im not quite sure
what happens to its response stream (null?) but the browser is now only
waiting for the second requests response - which I presume is a seperate
connection?

Now if we are using tokens or some such mechanism to detect that its a
second request and thus illigitimate then we can of course return some kind
of error to the user instead of processing the request (since we know its
already been processed).

This however isnt very friendly. What we really want to do is to have the
second request return the same response as would have been returned by the
first request after it did its work. I have no practical solution for this
:-(

Hmm. Actually I have an idea. Not a good one, but maybe worth a passing
thought:
(Thinking off the top of my head here  btw (and the following will not work
in a distributed environment unless one has sticky sessions so that all
requests for a particular session are gauranteed to be processed by the same
JVM)):

0. Requests A,B,C,N come in in rapid succession and cause threads to be
started in the container to process the requests - probably but not
necessarily in the order they came in.

1. Thread B (or any other thread) is lucky enough to start running first
and. Synchronizing on some global object (probably its own Class object if
its a singleton) it checks the session for a token (under a key that was
generated earlier and submitted as a request param in a hidden field). Not
finding it, it creates it and stores it in the session, and proceeds to
marshall the data needed to render a response - whatever it is the action is
supposed to actually do.

2. Threads A,C,N also sync on the global object and check the session.
Unlike thread B, they find the token, so they all call wait() on the token
object.

3. Having doing the processing  read/updated the db (or whatever), and
obtained the necessary info, etc... Thread B is finally ready to render a
response. It doesnt know however if it is the 'lucky last' thread that the
browser is actually waiting for. What it does then is to add the necessary
information to render the response to the session (perhaps the token could
provide getters for it?), and having done so it calls notifyAll() on the
token object, and then proceeds itself to forward to the view.

4. Threads A,C,N are woken up by the notify(), and proceed to grab the
necessary info from the session to render the same response that B is now
rendering and forward to the view. (NB: we shall assume that the view (jsp
or velocity template or whatever *only* renders the view and doesnt change
any of the information is uses to render the view (with one notable
exception) - and that that info can be read by multiple threads at once!).
One of these 4 threads is the lucky one (N in this example) that will
actually have their response output on the browser. 3 of them are wasting
time rendering to nowhere - but they are all rendering identical html, and
the user will get an appropriate response page instead of an error.

5. After they have finished rendering and flushed the 4 threads all try to
remove the token from the session. (You will note that if another request
comes in at this point we are in trouble. We could of course leave the token
in the session along with all the response data just in case but then we
would run out of memory after a while... (maybe we could use some kind of
self expiring cache? hmmm))

Now i can do the math within the validate Method of the according

Or is there a third way, to do it ?

I am using JDK 1.3, but this has got nothing to do with that.
This problem was fixed in Mar 2003 itself.

Maybe thats not the particular property file he is trying to load?

Try using

getServlet().getServletContext().getResourceAsStream( propertyFilePath );

In your actions execute method.

snip src=javadocs
This method is different from java.lang.Class.getResourceAsStream, which
uses a class loader. This method allows servlet containers to make a
resource available to a servlet from any location, without using a class
loader.

Re: What's the best way to do calculations ?

2003-09-10 Thread Jeff Kyser

Depends on your calculations.

I wouldn't do anything more than confirm proper data types
with validation - required fields are provided and of the
right type, etc.
If it is a trivial calculation that isn't used anywhere else,
then  you could do it in your Action's execute(),
but if it is a reusable calculation like loan payment
amount given a principal and number of months, etc.,
it sounds more like reusable business logic that should
be in a model object called by your Action's execute.

Re: What's the best way to do calculations ?

I think it should be best to keep as much business logic out of your 
actions. This helps you to decouple you application logic from it's 
presentation layer.
So, if you have to do some business specific calculations it would be best 
to perform them in some business logic class, like a Enterprise Java Bean.

Cheers,

Harm.

If you already have it in the request object, you might want to consider 
using javascript.
Maybe you can put the values of you second dropdown list in a html:hidden

Then use javascript to populate the second dropdownlist whenever the user 
changes the first one.

This is not an error.  Struts tries to use the encode method only

RE: What's a well defined Struts Project Structure?

2003-09-10 Thread Mainguy, Mike

I'm kinda in the middle of this whole process too and this is what I'm
leaning toward

MyProject   
  |- source(doesn't get deployed)
  |- documentation (doesn't get deployed)
  |- static (webserver stuff)
|- styles
|- javascript
|- images
  |- WEB-INF
|- pages -tiles (jsp) content pages 
|- templates -tiles (jsp) templates  
  |- classes  
|- tld
struts-config.xml
*-config.xml

I would say also that you could potentially have many subdirectories under
the pages/templates directories to reflect the complexity of your app...

i.e.

|- pages
 |- employeeScreens
 |- payrollScreens
 |- accountsPayableScreens

What a well defined struts project structure would look like?  I am always a
bit
hesitant with where to put things

Right now, I have:

  |- documentation

  |- jsps
|- styles

  |- WEB-INF
  |- classes
  |- bin
struts-config.xml
  *.tld

But I always run into problems with too many files in one folder or too few

mess
there too.  Just compare Tomcat and Struts, you will know what I am talking

RE: deployement issue

2003-09-10 Thread Robert Taylor

Try creating a simple web application with a single page using the
html:message .../. Run the web application on both systems and see
what happens.

Also, are the contents of the classpath for both systems
exactly the same? The fact is, something must be different if the web
app runs properly in one environment and not on the other.

Let me know what happens with the test web app. I know it may be a
pain to do, but it removes extraneous complexities and helps focus
in on the exact problem.

Its easy to create a simple web app using ServletExecs admin ui.
Let me know if you need help on how to do this.

1. Thread B (or any other thread) is lucky enough to start running first
and. Synchronizing on some global object (probably its own Class object if

finding it, it creates it and stores it in the session, and proceeds to
marshall the data needed to render a response - whatever it is the action is
supposed to actually do.

2. Threads A,C,N also sync on the global object and check the session.
Unlike thread B, they find the token, so they all call wait() on the token
object.

3. Having doing the processing  read/updated the db (or whatever), and
obtained the necessary info, etc... Thread B is finally ready to render a

information to render the response to the session (perhaps the token could
provide getters for it?), and having done so it calls notifyAll() on the

4. Threads A,C,N are woken up by the notify(), and proceed to grab the

As we realize so far, a browser window may send
request A to a server. The server starts thread A
to handle it. Before the thread A returns, the same

the server creates thread B to handle it.

Yes.   What happens to your first response is container-dependent, but from 
the point of view of Struts, it was generated and sent (I may be wrong, but 
I don't think Struts has a way to know it was lost).


 This however isnt very friendly. What we really want to do is to have the
 second request return the same response as would have been returned by the
 first request after it did its work. I have no practical solution for this

The best solution I've seen (WebObjects) handles it similarly to what Andrew 
suggests. 

All requests to the same session are serially-processed.

If the application is already processing a request, then another request 
won't be processed until the first one finishes.  This solves the 
synchronization issue.  You can't really solve the display issue without 
assigning unique identifiers to each request generated (see previous 
page-state cache email).   The client could be backtracking to another 
page with the same session, the same URL, and maybe the same form data.  On 
the other hand, is this a case of a difference that makes no difference is 
no difference?  At minimum, requests have to be identified with the same 
session, same URL, and same form data, though.  It will really depend on 
your backtracking strategy.

But once each request has a unique identifier and is being processed 
serially, you can compare a concurrent request to the request being 
processed, and send back the same response to both of them.


 (Thinking off the top of my head here  btw (and the following will not 
work
 in a distributed environment unless one has sticky sessions so that all
 requests for a particular session are gauranteed to be processed by the 
same
 JVM)):

Also true of the above.  WebObjects handles this by routing all requests for 
a given session to the same servlet instance.


 4. Threads A,C,N are woken up by the notify(), and proceed to grab the
 necessary info from the session to render the same response that B is now
 rendering and forward to the view. (NB: we shall assume that the view (jsp
 or velocity template or whatever *only* renders the view and doesnt change
 any of the information is uses to render the view (with one notable
 exception) - and that that info can be read by multiple threads at once!).
 One of these 4 threads is the lucky one (N in this example) that will
 actually have their response output on the browser. 3 of them are wasting
 time rendering to nowhere - but they are all rendering identical html, and
 the user will get an appropriate response page instead of an error.

Rather than render the view, just copy the response generated.  That avoids 
the above problems.


 5. After they have finished rendering and flushed the 4 threads all try to
 remove the token from the session. (You will note that if another request
 comes in at this point we are in trouble. We could of course leave the 
token
 in the session along with all the response data just in case but then we
 would run out of memory after a while... (maybe we could use some kind of
 self expiring cache? hmmm))

No, you must not cache the response at this point or page reloading/form 
resubmitting won't work.

A better solution would probably be to have the processing thread check to 
see if any other requests are waiting in the queue for the same response.  
If so, populate their response, wake them up, and clear the queuing 
condition.

RE: What's the best strategy to handle this kind of thread issues ?

It doesn't really defeat the effort - the only threads that will be sitting
there waiting are those that are processing requests that have come from
that particular form on that particular users browser where the user has
gone and double clicked submit etc... and we want things to proceed ok
without showing an error screen - and without saving the record twice in the
db (or whatever).

At any rate its unlikely to be worth the effort for most applications. I
present it more as an intellectual exercise than a serious proposal, (though
another Mike in a reply that just arrived mentions that WebObjects does
something not unlike this already so maybe its not so bad. Ill have to go
take a look at WebObjects if I ever get any free time...)

The simplest thing Ive found is to use some javascript on the client side to
minimise the potential for multiple submission of the form, and for those
cases it lets through (such as where js is disabled) the old fashioned
method of checking the token  showing an error page if its a double
submission will have to suffice. This of course is what we all do now
anyway, but a more elegant (from the user perspective) solution would be
nice.

Re: Cannot find bean viewcontactlist in scope request

paramName (in your case viewcontactlist) is the name of the bean in the

=beanProperty also.

From the docs:

Specify both the paramName and paramProperty attributes - The specified
property getter method will be called on the JSP bean identified by the
paramName (and optional paramScope) attributes, in order to select a value
that can be converted to a String.

RE: What's the best strategy to handle this kind of thread issues ?

Actually Id have to disagree with you about the requests for a particular
session not needing to be multithreaded.
For example in the app I was working on recently we needed the ability for
the user to pop up (yes I know - I dont like it either) lots of editing
windows for records selected from the listview in the main window,
furthermore the main window is itself framed... Its quite common for the app
to be processing several requests at once - and given the the app this is a
front end for is rather complex (It aint no shopping cart) and uses EJBS
down in the bTier, synchronizing requests for the same session would have
been unbearably slow (the average request can take a couple of seconds to
process depending on the BL going on behind the scenes - doing it serially
is out of the question).

implement Serializable, thats would be a bug!

heres a nasty hack: Perhaps you could add a transient field to your action
form:

public transient boolean _disableWrapper = false;

And override getServletWrapper thusly:

public ActionServletWrapper getServletWrapper()
{
  return _disableWrapper ? null : super.getServlet();
}

Prior to serialisation set the field to true. Serialise and then set it
back.

Oh and lose the formfiles, as for sure they will be the next problem -
unless you make their fields transient in your form.

Why on earth are you using an ActionForm as a parameter to an RPC though?
ActionForms are VIEW components. Very bad karma to use them as DTOs.

You would do better to create a normal bean class with the properties you
want and serialise that (you can use PropertyUtils.copyProperties() to
transfer the data from the ActionForm to the DTO if you dont fancy a lot of

have followed the tutorial in order to register the type mapping.

I tried to register the ActionServletWrapper class also but then I get:

I suppose that ActionForm can be seen as a simple Javabean. Any clue on what

I'm assuming it's a configuration issue with your AXIS implementation.
But rather then get into that... why not just create a interim bean that
will store the data then BeanUtil.copyProperties it back to the ActionForm?

1. There is absolutely no way to prevent users from making whatever 
requests
they want. Bookmarking, typing in URLs, emailing URLs, etc. are all 
possible
and there is nothing that can be done to prevent people from making these

Subject: RE: What's the best strategy to handle this kind of thread issues?

 My undertsanding was that the browser will only show the response to the
the
 second of the requests - forgetting about the first. The server of course
 hasnt forgetten about it and keeps processing (one hopes). Im not quite
sure
 what happens to its response stream (null?) but the browser is now only
 waiting for the second requests response - which I presume is a seperate
 connection?

It is very likely for the browser window to use the same connection to send
request A and B (with the keep alive setting). But I am not 100% sure for
this. Any Tomcat users or experts could provide some clue?

 Now if we are using tokens or some such mechanism to detect that its a
 second request and thus illigitimate then we can of course return some
kind
 of error to the user instead of processing the request (since we know its
 already been processed).

Assume the token is used. Thread B returns error messages. But thread A
is still valid in the processing mode. When thread A returns with response
A,
the difficulty here is the browser window could *ignore* response A.
If the browser window shows response A, it is much better.

 This however isnt very friendly. What we really want to do is to have the
 second request return the same response as would have been returned by the
 first request after it did its work. I have no practical solution for this
 :-(

I have the same expectation and am considering using the very first
filter to 1) block other threads or 2) render the pending contents from
thread A.
But we have real challenging issues here as you see my comments below.

 Hmm. Actually I have an idea. Not a good one, but maybe worth a passing
 thought:
 (Thinking off the top of my head here  btw (and the following will not
work
 in a distributed environment unless one has sticky sessions so that all
 requests for a particular session are gauranteed to be processed by the
same
 JVM)):

 0. Requests A,B,C,N come in in rapid succession and cause threads to be
 started in the container to process the requests - probably but not
 necessarily in the order they came in.

 1. Thread B (or any other thread) is lucky enough to start running first
 and. Synchronizing on some global object (probably its own Class object if
 its a singleton) it checks the session for a token (under a key that was
 generated earlier and submitted as a request param in a hidden field). Not
 finding it, it creates it and stores it in the session, and proceeds to
 marshall the data needed to render a response - whatever it is the action
is
 supposed to actually do.

 2. Threads A,C,N also sync on the global object and check the session.
 Unlike thread B, they find the token, so they all call wait() on the token
 object.

 3. Having doing the processing  read/updated the db (or whatever), and
 obtained the necessary info, etc... Thread B is finally ready to render a
 response. It doesnt know however if it is the 'lucky last' thread that the
 browser is actually waiting for. What it does then is to add the necessary
 information to render the response to the session (perhaps the token could
 provide getters for it?), and having done so it calls notifyAll() on the
 token object, and then proceeds itself to forward to the view.

This could open a bad time window for other threads to modify data models
while thread B is rendering the view.

 4. Threads A,C,N are woken up by the notify(), and proceed to grab the
 necessary info from the session to render the same response that B is now
 rendering and forward to the view. (NB: we shall assume that the view (jsp
 or velocity template or whatever *only* renders the view and doesnt change
 any of the information is uses to render the view (with one notable
 exception) - and that that info can be read by multiple threads at once!).
 One of these 4 threads is the lucky one (N in this example) that will
 actually have their response output on the browser. 3 of them are wasting
 time rendering to nowhere - but they are all rendering identical html, and
 the user will get an appropriate response page instead of an error.

We could not assume thread A,C,or N are to render the same response as B.
They could have different handling logic.

 5. After they have finished rendering and flushed the 4 threads all try to
 remove the token from the session. (You will note that if another request
 comes in at this point we are in trouble. We could of course leave the
token
 in the session along with all the response data just in case but then we
 would run out of memory after a while... (maybe we could use some kind of
 self expiring cache? hmmm))

This removing/resetting a token form the session mechanism is not
guaranteed to work. For example, when thread B is rendering its view,

Transaction Token will help, but it will not do everything you want to do.
Max is right, this is the nature of Web application.  Even with Transaction
Token user, if he has a copy of the token, can still create request and hit
your app without the app knowing about.  Plus, not every resource in your
app. Will have a transaction token, even if it is a lot of effort need to be
made for every request to check and update token.

It filters certain characters for security reasons.  In general, it's a
bad idea to store markup in properties files because that's a view layer
issue.  You could try using the JSTL's fmt:message tag.

Hi;

These are a couple of suggestions I have for the next version of struts:
  1.. Can get the session in the ActionForm constructor. This would be very useful for 
initializing with data attached to the session.
  2.. Have a pre-page method in the Action that can be set in an action like 
validate=true. This would give the Action class a chance to determine if this page 
can be displayed and do a forward if it cannot. For example in pages 2 - N of a 
multi-page series of forms.
  3.. Allow an action with no form. This would be useful where a page has a form 
that is just a submit button. No ActionForm is needed but the html:form is still 
prefered for the action it submits to.

 I think, however that this proposed solution (almost) entirely defeats the
 purpose of having a multithreaded environment.  If you try and synchronize
 all responses and disregard duplicates, you will most likely end up with a
 slow and cumbersome application.

Swing takes advantages of multithreaded environments. But its event
handling model does use single thread to execute queued events.
Such mechanism does not cause slow responses at all,
both in theory and in reality. How to get it done in web tiers is an open
challenging.

 I would say to achieve the sort of efficiencies you are describing one
would
 be better served to look into the app/web server code.  Doing this at a
 servlet level will most likely just get one into a big mess.

 It actually seems like a good idea (if it isn't already there) for a

html:select within logic:iterate

2003-09-10 Thread Tobias Salem


Hello,

I have a problem with auto-updating some properties with html:selects within
an iterate-tag.
The JSP is a classic view/edit cart page where you view and possibly edit
your shopping cart. The form is called CartForm and only have one instance
variable called trade (an own-written class Trade), through which all
relevant data is retrieved and/or updated.

The Trade object contains a list of products which are part of the trade.
For these the title and price should be displayed (no problem here), and the
quantity and deliveryMethod should be displayed and updateable through
html:selects. The problem is how to write the correct html:select syntax to
map to the correct methods in the CartForm (which just translates/forwards
the call). Everything except the html:selects are working fine. I have read
alot of forums/articles and tried over 20 syntax variants but still with no
luck. :(

Here is the relevant code:

/**
 * Class representing the form used to view/edit the cart,
 * subclassing the CustomerForm (extends ActionForm)
 * What differs in this CartForm is that it has Trade info
 * (the tradeProducts of the Trade are what constitutes the 'cart').
 *
 */
public class CartForm extends CustomerForm  {

private static Logger logger = Logger.getLogger( CartForm.class);

protected Trade trade;

public Trade getTrade() {
return trade;
}

public void setTrade(Trade t) {
trade = t;
List l = trade.getTradeProducts();
logger.debug(CartForm.setTrade(Trade t) called);
logger.debug(This CartForm now has  +l.size() +  nr of TradeProducts  +
l);
}

// returns the list of TradeProducts which are part of the trade/cart
public List getTradeProducts() {
return trade.getTradeProducts();
}

// Methods added from similar example at
http://jakarta.apache.org/struts/userGuide/building_controller.html
// but Are these getters and setter really needed?
// The get/set methods should IMHO be called directly on the
TradeProduct objects
public int getQty(int i) {
logger.debug(Getting qty on TradeProduct nr  +i+ .);
TradeProduct tp = (TradeProduct) trade.getTradeProducts().get(i);
return tp.getQty();
}

public void setQty(int i, int value) {
logger.debug(Changed qty on TradeProduct nr  +i+  to value  + value);
TradeProduct tp = (TradeProduct) trade.getTradeProducts().get(i);
tp.setQty(value);
}

public String getDeliveryMethod(int i) {
TradeProduct tp = (TradeProduct) trade.getTradeProducts().get(i);
return tp.getDeliveryMethod();
}

public void setDeliveryMethod(int i, String value) {
logger.debug(Changed setDeliveryMethod on TradeProduct nr  +i+  to value
 + value);
TradeProduct tp = (TradeProduct) trade.getTradeProducts().get(i);

}

}

/**
 * This class models a TradeProduct.
 * A Trade respesents one purchase-event and can consist of one or many

  private int qty = 1;
  private String deliveryMethod = ;

public int getQty() {
return qty;
}
public void setQty(int _qty) {
qty = _qty;
}

public String getDeliveryMethod() {
return deliveryMethod;
}
public void setDeliveryMethod(String _deliveryMethod) {
deliveryMethod = _deliveryMethod;
}

}

viewCart.jsp

...
  logic:iterate id=tp property=tradeProducts indexId=ctr
!-- These are working fine --
html:hidden property=code name=tp value=product.productNr /
html:hidden property=price name=tp value=product.price /
  !-- What is the correct syntax for the html:selects?? --
  html:select indexed=true name=tradeProduct property=qty
onChange=this.form.submit()
html:options property=qtys/
  /html:select

  html:select indexed=true name=tp property=deliveryMethod
onchange='this.form.submit();
html:options property=deliveryMethods/
  /html:select
...
/logic:iterate
...

With this syntax no error occurs but no update of the qty or deliveryMethod
occurs. If I remove the indexed=true it says that setter methods for qty
and deliveryMethod is missing, which is a lie since a TradeProduct has
those, and tp points to a TradeProduct.
Any help is much appreciated. A complete example html:selects withing a
logic:iterate which auto-update properties in the form (or classes
referenced by the form) would be great.

Thanks in advance.

 These are a couple of suggestions I have for the next version 
 of struts:
   1.. Can get the session in the ActionForm constructor. This 
 would be very useful for initializing with data attached to 
 the session.

This violates the JavaBean standard which requires that beans have a default (no-arg) 
constructor. You can get to the session -- or whatever scope object you need -- via 
the validate(ActionMapping, HttpServletRequest) method inherited from ActionForm.

   2.. Have a pre-page method in the Action that can be set in 
 an action like validate=true. This would give the Action 
 class a chance to determine if this page can be displayed and 
 do a forward if it cannot. For example in pages 2 - N of a 
 multi-page series of forms.

I agree that a general page-flow restriction mechanism would be a boon. I've had to 
develop my own, and I'm sure I'm not alone in this.

   3.. Allow an action with no form. This would be useful 
 where a page has a form that is just a submit button. No 
 ActionForm is needed but the html:form is still prefered 
 for the action it submits to.

I don't understand. If the page has no form, why would you need a submit button 
instead of just a link? You could also just use a regular HTML form tag that 
directly submits to the URL of the action in question.

In any case, action mappings aren't required to have a name attribute. From 
struts-config_1_1.dtd:

 nameName of the form bean, if any, that is associated with this
 action mapping.

 As we realize so far, a browser window may send
 request A to a server. The server starts thread A
 to handle it. Before the thread A returns, the same
 window may send request B to the server, therefore
 the server creates thread B to handle it.

Technically, the threads are usually there already in a pool, rather than
being created, but that is not really relevant to your question.

The only ways the same browser window can send more than one request
(in the manner you describe) are:
(a) User presses STOP and then manually triggers a second request.
(b) A page includes one or more tags like img that fire
off parallel requests for each image
(c) Window includes multiple frames (the frames themselves
are often loaded with parallel requests) just like (b)
(d) JavaScript techniques similar in (b) that are used by the client
to reassemble the output.

So the answer to your question really depends on which use case we're
talking about.  In scenario (a), thread A will continue to run the
original request, because the server has no way to know that the user
pressed STOP.  Because the client has closed the TCP connection, the
servlet will generally encounter an I/O exception when writing out the
response -- but if the response fits inside a buffer, it might not be seen
until after the servlet returns.

In scenarios (b) - (d) the requests run in parallel and the client
assembles the resulting page.

 Assuming thread B finishes earlier than thread A, we
 could have the following possibilities:

 1) The server waits thread A to finish and send response A
 and then send response B. (I do not believe this is the
 Tomcat implementation, correct?)

 2) The server sends response B back to the browser
 window and the browser window displays it and ignores
 response A after it.

  3) The browser displays response B and then displays
 response A.

 What I can see is that thread B is the trouble maker. But it
 is possible when end users click more than one buttons.

This is my scenario (a) use case, and behaves as I described above.

 In Swing, such problems are resolved by Single Thread
 Model. Should we follow Single Thread Model at
 servers? Are there any other practical solutions to it out
 there?

The key problem in dealing with scenario (a) is detecting that it has
even happened.  The most important case is when you're doing a POST that
updates the database -- for example, you don't want an order to be
submitted twice simply because the user pressed SUBMIT, hit the back
arrow, and pressed SUBMIT again.  The transaction token facility
provided by Struts can be used to detect the second submit.

Note that there is an API called SingleThreadModel in servlets, but it
has nothing to do with this kind of problem, and should be avoided anyway
(it's being deprecated in Servlet 2.4) because it doesn't really solve all
of the problems that it tries to solve.

 this. Any Tomcat users or experts could provide some clue?


This is actually more an issue of the client than the server.  Tomcat 4.x
and 5.x do, in fact, support HTTP/1.1, which includes the ability to send
more than one request serially on the same TCP connection.  However, if
you're doing scenario (a) from my previous response (user presses STOP),
then the client knows it needs to switch to a different TCP connection
because it hasn't received the first response yet.  In scenario (b)-(d) --
for example, multiple img tags -- the client will open separate TCP
connections for simultaneously pulling images (Netscape used to default to
4).

Under no circumstances will a client that correctly implements HTTP send a
second request on the *same* TCP connection as a previous one without
having received a response yet.  Of course, whether it's the same TCP
connection or a different one makes absolutely no difference in the fact
that you do need to deal with the SUBMIT -- STOP -- SUBMIT behavior of
users.  How the client and server communicate (one socket versus many, one
request per socket or persistent connections) is an irrelevant technical
detail.

 Subject: Suggested enhancements for next version

 Hi;

 These are a couple of suggestions I have for the next version of struts:

   1.. Can get the session in the ActionForm constructor. This would be
 very useful for initializing with data attached to the session.

   2.. Have a pre-page method in the Action that can be set in an
 action like validate=true. This would give the Action class a chance
 to determine if this page can be displayed and do a forward if it
 cannot. For example in pages 2 - N of a multi-page series of forms.

   3.. Allow an action with no form. This would be useful where a page
 has a form that is just a submit button. No ActionForm is needed but the
 html:form is still prefered for the action it submits to. thanks -
 dave

The best way to record suggestions like this is to put enhancement
requests into our issue tracking system:

Hi

I want to generate a link from a file name which is a property from an
action form. Can I generate one with html:a whose href is this
property?
Something like

class MyForm extends ActionForm
{
  private String myFile;

  public void setMyFile (String MyFile)
  {
this.myFile = MyFile;
  }

  public String getMyFile()
  {
return this.myFile;
  }
}


and later do something like:
html:a property=myFile/

I have RTFM and seen that I can do some sofisticated stuff with
parameters, but I want to do this (I think) simpler thing. Is this
possible?

I don't think you need the .do extension, unless you have that defined
in the web.xml mapping. 

If you use html:form, Struts is supposed to find a form bean defined
either through the action mapping or the name attribute in the tag
html:form..., if you don't really need a from bean, then use the
standard html form tag, ie. 

form action=
input type=text ...

Reversing the mapping between content-JSPs and Tiles definition

2003-09-10 Thread Marco Tedone

Hi guys,

as you'll probably know, I'm realizing a utility to realize a search in a
web site using Struts and Tiles. I'm nearly there. The only problem I've got
is that the indexed pages are the one containing actually the content (let's
say contenta-body.jsp, contentb-body.jsp), while the pages mapped against a
Forward are usually JSPs which define a Tiles definition (i.e. named
contenta.jsp, content.jsp), which, therefore, are empty.

Now, I would need, starting from a JSP with content defined in the
tiles-definition configuration file, to retrieve the page to which it
belongs to. For instance:

contenta-body.jsp - contenta.jsp
contentb-body.jsp - contentb.jsp

I presume that, like struts configuration information can be retrieved from
the ModuleConfig object, than the tiles-definition information can be
retrieved in some TilesConfig object.

I would need access to Tiles API and possibly documentation, but I don't
know if this is part of the Struts project, or a project itself, and where
to find eventually code and Javadoc.

Could please someone give me advise on it?

Thanks,

Marco

Client side validation when using validation against Action path

2003-09-10 Thread Yuan, Saul (TOR-ML)

Hi,

I'm using the Validator to validate against an action path (rather than
a form), it works fine on the server side. But it doesn't work on the
client side using javascript. All the javascripts are spitted out as
text, I noticed the starting and ending script tag is missing in the
generated javascript. I wonder what the problem could be. I have the
following in my jsp file:


html:form action=/addAsset.do enctype=multipart/form-data
onsubmit=return validateAssetForm(this);


html:javascript formName=assetForm dynamicJavascript=true
staticJavascript=true /


and should I use addAsset or /addAsset for the formName attribute?
It doesn't work either.


thanks,

RE: Tiles problem?

2003-09-10 Thread Yann Lebreton

My understanding with tiles is that they act like a server-side include. 
Meaning they are self contained and therefore doesn't know anything of the page that 
called it.

As a result whatever you place in the page scope should not be known by the tile since 
it's a different page. So, it should never have worked.

Well, the tile which is referenced with the attribute billingAddress is

- The code is working with sturts 1.1 beta xy? Sorry I can not find out
which beta it was. Now I use 1.1 final.

- My tiles definitions are in a seprate file -- tiles-defs.xml
- I hava a master layout jsp page where usually only the body part is
changing.
- One of the body tiles is called: let's say 'tile1' referencing a jsp page:
let's say page1
- I have another tile (tile2) referencing page2 which is inserted in tile1

The structure of the pages is as follows (Comments start with ***):

page1 (tile1):

html:form action=/RegisterAddressAction.do
*** RegisterAddressAction.do works with an actionformbean ( lets call it
AFB1 which isdefined in struts-config.xml) which has a getter to get orderFB
nested:nest property=orderFB
  nested:text property=billingEqualShippingAddress /
/nested:nest
*** -- Cedric told me I can not use tiles in a nested context. -- so I
close the nested context before tiles:insert

/html:form

page2 (tile2):

*** because the information I want to display is in
AFB1--orderFB--orderBean I start to nest again in tile2

 nested:nest property=orderFB
 nested:nest property=orderBean

*** here the problem starts. the property invoiceCompany can not be

  nested:text property=invoiceCompany size=50 maxlength=50/

Again, this code is working with beta versions of struts 1.1.

javascript with struts nested fields?

2003-09-10 Thread David G Friedman

In an html page, is there a way to reference a nested form variable without
using array subscripts?

In the web page the client sees, it gets the below:

input type=text name=order.program value=108

I want a pop-up calendar window button next to it that populates that field
with the selected date.  When I switched from program to a nested field
named order.program, it broke.  The program can be referenced by
formName.program but the nested one causes javascript errors trying to
reference it as fornName.order.program.   I don't want to use
fornName.elements[XXX] since any changes to the page layout might reorder
fields and change those array subscripts, making development very messy.

Transaction Token will help, but it will not do everything you want to do.
Max is right, this is the nature of Web application.  Even with Transaction
Token user, if he has a copy of the token, can still create request and hit
your app without the app knowing about.  Plus, not every resource in your
app. Will have a transaction token, even if it is a lot of effort need to 
be
made for every request to check and update token.

Keep these things in mind as you develop a solution:

1. There is absolutely no way to prevent users from making whatever
requests
they want. Bookmarking, typing in URLs, emailing URLs, etc. are all
possible
and there is nothing that can be done to prevent people from making these
requests.

2. You do have total control over how your web app responds to those
requests.

  Hi;

  These are a couple of suggestions I have for the next version of struts:

1.. Can get the session in the ActionForm constructor. This would be
  very useful for initializing with data attached to the session.

2.. Have a pre-page method in the Action that can be set in an
  action like validate=true. This would give the Action class a chance
  to determine if this page can be displayed and do a forward if it
  cannot. For example in pages 2 - N of a multi-page series of forms.

3.. Allow an action with no form. This would be useful where a page
  has a form that is just a submit button. No ActionForm is needed but the
  html:form is still prefered for the action it submits to. thanks -
  dave

 The best way to record suggestions like this is to put enhancement
 requests into our issue tracking system:

 No, it just means that triggering a second request implicitly executes a

The behaviors of IE browser windows will always STOP the first

It looks right. If so, there is no way/need to block or cancel thread B.
Just let it return error message and then we find a way to pull out the

java.util.Date in a Bean/ActionForm

2003-09-10 Thread Cees van de Griend

L.S.

I'm new at Struts, but I got it working.

I've an simple Bean with a java.util.Date property and the set and get methods 
with to set/get the java.util.Date values. I've an (almost) working 
ActionForm with the same properties.

In a Action I use somthing like: 
org.apache.commons.beanutils.PropertyUtils.copyProperties(form, bean) to copy 
all the properties from the bean to the form and forward to a JSP page to 
edit the properties in an HTML-form. So far, all is well; the date is 
displayed like '2003-09-10' in an text-field.

If I submit this page, a 'IllegalArgumentException: argument type mismatch' is 
thrown. If I remove all the java.util.Date code, all is working as expected.

Clearly I'm doing something wrong with the java.util.Date.

What is the best way to get a date from a HTML-form to a Bean?

Cees.

YASJR (Yet Another Struts Justification Request)

2003-09-10 Thread Gregory F. March


I seem to have successfully pushed Struts in my company (a big Wall
St. bank).  However, today, I was asked the following question:

How can I guarantee that there are no hacks, bombs, etc. in the
Struts code or any OS code for that matter?

My immediate response was, how can you guarantee it for any code?
However, being a large bank with literally trillions of dollars a day
passing though our systems, I can definitely understand their concern.

At a minimum, we will obtain the source code and at least do a minimal
code walk-through and then compile our own binaries.

What other guarantees can I make to my management?  What is the process
the Struts team uses to control a rogue contributor?

Thanks,

Quick template question

2003-09-10 Thread Stephane Grenier

Hello all.

I've got the following template file:

%@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %
template:insert template='/tilesExample.jsp'
 template:put name='title' content='Templates' direct='true'/
 template:put name='header' content='/header.html' /
 template:put name='sidebar' content='/menu.html' /
 template:insert name='content' content='/content.html' /
 template:put name='footer' content='/footer.html' /
/template:insert

Is there a mechanism to have just one file rather than 2 seperate files for the 
content ? Is it possible to at least replace the line:

 template:insert name='content' content='/content.html' /

with just the html code for that page directly in this file ? And if so how would I do 
that ?

Thank you,
Stephane

There are rather few committers than can change the code base (roughly
10-15 people).  All commits are mailed to struts-dev for the team to
review.  Even if Struts were secretly hacked, it isn't all that much code
to review anyways (about 14,000 lines of non-test/example code).  You
could narrow your code review to only the packages you'll actually be
using.

You will always have access to the source to do security reviews unlike

RE: Serializing ActionForm (Urgent)

2003-09-10 Thread António Santos


Hi Andrew and Gin,

Thanks for your help. I will try to use intermediate DTOs (simple Javabeans)
and hope that AXIS serialize them well (I'm afraid about FormFile). However,
and since ActionForms comply to the JavaBean specification, I was wondering if
it would be a good idea to have this serialization problem fixed. I don't
think that it's that handy to have ActionForms to hold the data entered in a
HTML form and then having to copy the data to a simple DTO in the Action class
in order to have it serialized and sent through an RPC.

Thanks for your tips,

António Santos
FEUP - Portugal

Hmm. I was about to finger the ActionServlet reference, and the
MultipartRequestWrapper ref, but they are both transient, so can't be
causing the problem.
My next suspect would be the FormFile (but its the actionservletwrapper its
listing in the except... ahhh... but of course its a wrapper - not the ref
itself - the ActionServlet reference is transient, but the *wrapper* object
a new instance of which is returned on each call to getServletWrapper()
doesnt implement Serializable.

Hmm. You cant do much about that. IMHO given that ActionForm claims to
implement Serializable, thats would be a bug!

silly-idea
heres a nasty hack: Perhaps you could add a transient field to your action
form:

public transient boolean _disableWrapper = false;

And override getServletWrapper thusly:

public ActionServletWrapper getServletWrapper()
{
 return _disableWrapper ? null : super.getServlet();
}

Prior to serialisation set the field to true. Serialise and then set it
back.

Oh and lose the formfiles, as for sure they will be the next problem -
unless you make their fields transient in your form.
/silly-idea

Why on earth are you using an ActionForm as a parameter to an RPC though?
ActionForms are VIEW components. Very bad karma to use them as DTOs.

better-idea
You would do better to create a normal bean class with the properties you
want and serialise that (you can use PropertyUtils.copyProperties() to
transfer the data from the ActionForm to the DTO if you dont fancy a lot of
typing...).
/better-idea


---

I'm assuming it's a configuration issue with your AXIS implementation.
But rather then get into that... why not just create a interim bean that
will store the data then BeanUtil.copyProperties it back to the ActionForm?

Looks like it should work, you might need to escape the slashes.

It's easy enough to test either by using grep on the command line (which is
not the best test since there are differences btw Unix regexp and Java

doesn't use the Java regexp package) or by using the ORO test applet at

Offer them kool aid.
It will make them feel better.
Write 'Struts Good' in the bottom of the cups though.
Now they associate the good taste of kool aid with Struts!

RE: Valid Regexp for MM/dd/yyyy matching in a string?

2003-09-10 Thread Chen, Gin

That doesnt look very Y3K compliant :-P
If you have complex logic then best thing to do is to create a custom date
validator.
The code would be really simple and will catch cases where people might
enter in:

19/39/1000

Btw.. why not just use the date validator? It will handle exactly that
format easily

Looks like it should work, you might need to escape the slashes.

It's easy enough to test either by using grep on the command line (which is
not the best test since there are differences btw Unix regexp and Java
regexp) or by writing a test class that uses the ORO library (Validator
doesn't use the Java regexp package) or by using the ORO test applet at
http://jakarta.apache.org/oro/demo.html.

Re: Valid Regexp for MM/dd/yyyy matching in a string?

2003-09-10 Thread Michael Ruppin

This might provide more ideas for your regexp pattern, it works with egrep:
 
^((0?[1-9]{1})|(1[0-2]{1})){1}[/]((0?[1-9]{1})|(1[0-9]{1})|(2[0-9]{1})|(3[0-1]{1})){1}[/][0-9]{4}$
 
Not sure about the date validator.  Does it prevent submission of 2/29/2003?  I do 
everything server side ;)

DynaForms and validation

2003-09-10 Thread Barry Volpe

Hi,

I have setup a DynaActionForm and wish to perform validation.
How is this done when I do not have an ActionForm which requires
extending org.apache.struts.validator.ValidatorActionForm 

Thanks,
Barry

RE: YASJR (Yet Another Struts Justification Request)

2003-09-10 Thread Steve Raeburn

Congratulations and thanks for evangalising Struts to your organization.

 How can I guarantee that there are no hacks, bombs, etc. in the
 Struts code or any OS code for that matter?

The clue is in the title - OPEN source :-)

If open source has a weakness it certainly is not that anyone is hiding
things in the code.

If they're worried about rogue committers -- and I'd say we're probably all
rogues ;-) -- you can monitor the struts-dev list and be notified of every
single change to the codebase as it happens. I bet you can't get that level
of reassurance from any commercial vendor.

Out of interest, what web server is your bank running its website on?
Apache, by any chance? :-)

Steve

Btw, does using filter drain much performance? Is there any other way to ensure 
that one can't access the jsp files without being logged in? A bean in every jsp page?

html:form; action attribute problem

2003-09-10 Thread Kumar M

Hi all,

I have a question re the action attribute of a html:form.  The html:form is 
spread over a few tiles. Currently, its value is populated using a run time 
expression

html:form action='%= (String)request.getAttribute(FORM_ACTION) %' 
method=POST

But some times, the page that I need to display may not have any associated 
mapping. But the problem is I cannot seem to find a way to indicate that to 
struts. If there is no FORM_ACTION attribute on the request I get a NPE. If 
I put something generic then I would have to create a dummy mapping by that 
name.

How do I check to see if FORM_ACTION is null and then insert the action 
attribute (or not).

Thanks in advance.

The only potential rogue contributor that could possibly affect
things is someone who has commit access on the CVS repositories (there's
roughly 20 people with commit access on Struts, about half of that number
is active recently).  Any contribution from anyone else has to be go
through a committer before it actually becomes part of Struts.

In addition, all commits of changes to the codebase by *any* committer are
mailed to the STRUTS-DEV list, and are thus available for inspection by
all of us.  No surprises.

A more strategic mechanism relates to how committers become committers in
the first place -- by being voted in by the other committers on that
project, after having demonstrated themselves to be both smart and
trustworthy.  All of the current committers went through this gauntlet,
and I have a high degree of confidence that we don't have any closet
rogues in our midst :-).

For more info on how Apache projects (including Jakarta, which includes
Struts) make decisions and do things, you might find the following stuff
