update values in a collection of beans through JSP

[Muhammad Momin Rashid]

Hello,

I have a collection of a perticular type of bean.  I am displaying the
values of fields in each bean (bean values are of type strings, boolean
etc.) inside a logic:iterate.  The problem is when I change any value in the
webpage, the bean in the collection does not get updated.  Can anyone guide
me how to accomplish this?

Thanks for your time and effort

Regards,
Muhammad Momin Rashid.

Re: updating values in a collection of beans through JSP

[Richard Yee]

Muhammad,
The JSP is evaluated on the server and then sent to the browser. When you 
change a value on the web page, you submit the form to an Action class 
which then takes the form properties and should update your collection and 
then persist it or put it in request or session scope. You can then forward 
to another JSP to re-display the updated collection.

Re: duplication of codes in different Action class

[Sebastian Ho]

I am already using DispatchAction.

I didn't use the scope in my action-mapping. Instead I use
session.setAttribute in my Action.

The codes to update the actionform is in action1. But I need to update
the same form in action2. One way is to duplicate the same codes in both
action. Or the common update codes can be executed before a JSP is
loaded. The latter will prevent duplicate codes.

forwardPattern in -XML-Element

[Matthias Wessendorf]

Hi folks,

just a question on forwardPattern of .
Perhaps i missed something.

Default value is $M$P, which means,
module and path.

so what would be a good example of changing this
behavior?

Well everything should be going through an Action of some sort so "yes" 
just make sure the form is populated in your Action before forwarding on 
to the JSP.

To prevent this, I actually need to use hidden fields in my JSP or some
other ugly solutions in my Action class. They are still dependent on
each others afterall.
You can handle this several ways...
For example, one solution is you create a TransferObject that refers to 
only the fields you care about - in this case the 4 fields you 
mentioned. So your call to the business layer would return that 
TransferObject and you could then convert that easily to your form 
(using BeanUtils). Then going back the other way your business layer 
would take as an arguemnt the same type of TransferObject.

I actually don't prefer the above, though, because say later on you 
decide you want to add another field to your form now your backend has 
to worry about handling a new object with different fields.

I think the best solution is to simply make another call to get back the 
initial TO from the db, then simply use BeanUtils to populate that TO 
with the form fields. It will only set the fields in which it has the 
same names for so your other data will be fine.

So it looks like...
TransferObject to = BackendEnd.getMyTransferObject(..);
MyForm myForm = (MyForm)form;
BeanUtils.copyProperties( to, myForm);
BackEnd.doUpdate( to );
Pretty simple I think. Just make sure your ActionForm doesn't contain 
properties that you don't care about editing otherwise it will 
over-write the TO properties. If the JSP form is going to be very 
dyanmic, as in it will sometimes have some properties and sometimes have 
others, then you will have to use more complex 'tricks' such as using 
hidden variables.. or I'd just prefer to manually set the TO fields in 
the Action.

Then again, since html:text is usually used with a form bean, which is
supposed to be all strings, you could format them yourself, either in
the setter (yuck), or in the action.

Antw: Re: using struts and dbcp together throws sometimes a NoSuchElementException/SQLNestedException:

[PANTA-RHEI WOLF]

Hi Erik,

this is what i really do,
i believe that closing the connection will close automaticly the statement and the 
resultset, or?
the point is, i work with the resultset in a function, which is hidden from the db 
access,
so there i only have my resultset. From these i try to get the statement and from the 
statement i try to
get the connection. If there are all of these 3 not null i close the connection.
Yes i know it looks a bit strange, but depending on the javadoc these should do the 
same.

// this checks if the rset is available and if the statement is available and if the 
connection is available
if (rset!= null && rset.getStatement() != null && rset.getStatement().getConnection() 
!= null) { 
rset.getStatement().getConnection().close();
}

Never the less this seems to work, but sometimes i got an exception saying that my 
pool is exhausted... 
and this is what i do not understand. i checked if this connection i borrow and the 
connection i close
are the same and yes they are... so hey what is the problem? Can it be that i borrow 
my connections
to fast from the pool?
Sometimes 3 till 10 per second, but they are released immediately.

Any ideas how to avoid this exception

org.apache.commons.dbcp.SQLNestedException: Cannot get a connection, pool exhausted

I always:

catch ()

Not sure if that is it, but I don't understand your logic for deciding

so JSP1 should be associated with another Action,

You should make your Action not the JSP1 available to

It's unclear:)
Some of you terminology might just be wrong which is making it more 
confusing. For example in step 2 above, are you setting the form in 
session scope yourself? You normally don't need, or want, to manually do 
this. You delcare the scope of your form in your action mapping.

I think what you are wondering about is "How do you get your form 
populate for your JSP so that that user can alter it?" (I could be wrong 
here)... anyway I like to use a DispatchAction which has several methods 
in it... setUp, Update, etc. So your first call when the user clicks on 
a link would call the setUp method and there you would make sure your 
form is populated with the data it needs and you forward to your JSP. As 
a side note, you do not need to be using Session scope for this. Do you 
have a particular reason why you need to be using Session scope for your 
form (many times you do, but I'm guessing in this case you don't and you 
are using the Session because you are not understanding the flow of how 
Struts operates).

ActionForm and Transfer Object

[Sebastian Ho]

Hi

People have been telling me that ActionForm should not be dependent on
your TO. Simple because actionForm is for presentation and TO for your
business requirement. Sounds logical and right way to go.

Now that I started developing using struts, it is actually not that
simple. 

Say I retrieve a TO from database and convert it into a actionForm for
display. In this case I have 4 fields for my actionForm but 10 in my TO.
(6 are not needed for display). A user updates the 4 fields and the
action convert those into TO. In this case, the other 6 fields will be
reset to null(or empty) in my database!

To prevent this, I actually need to use hidden fields in my JSP or some
other ugly solutions in my Action class. They are still dependent on
each others afterall.

Is there a solution to this or I am missing something here?

Thanks

Take a peek at
http://struts.apache.org/userGuide/struts-html.html#checkbox
especially the "WARNING".  Now compare the working form and the
not-working form.  They should give you a clue.  ;)
(If they're both the same ActionForm's, then THAT's something strange.)

submitting map-backed action forms

[Olve Sæther Hansen]

Ok, trying once more, hopeing for more help this time..
I have a jsp, getting values from an action. These values represent 
questions, and alternatives for each question rendered as radio-buttons.

The radiobuttons is preset to a choice if the user has visited and 
answered this question before, but he/she is free to revise the answer. 
So far I got it to work (by hardcoding the values sent from the action 
-  just for testing).

I am using the general approach from:
http://struts.apache.org/userGuide/building_controller.html#map_action_form_classes 

My problem comes when submitting the form, I get a:
javax.servlet.ServletException: BeanUtils.populate
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:844)
at 
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.java:823)

org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:157)
at 
org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:68)
[snip]
The two actions involved is defined as:
* @struts.action name="mapValueForm" path="/answerQuestionGroup"
* parameter="action" scope="request"
*
* @struts.action name="mapValueForm" path="/openQuestionGroup"
* parameter="action" scope="request"
The form is defined as:
private Map values = new HashMap();
Object getValue(String key)
{return values.getKey(); }
void setValue(String key, Object value)
{ values.put(key, value); }
The form is specified as:



 


  <%--Todo: legg til innrykk--%>


<%-- Here I am retrtieving the value from mapValueForm, and it works --%>

  





  


As far as I understand, struts should use 
mapValueForm.setValue("someVal") when submitting this form. The 
generated html looks sane, in that it generates the following for a 
question with three alternatives, and one is checked (the hardcoded val 
from the action):

ja  
nei  
 kanskje 

I have struggled with this problem for some time now, please anyone who 
can help me with a pointer to what can be wrong, or how I can do this in 
another way?

Re: forward and set url parameter

[Erik Weber]

public ActionForward executeActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response) throws Exception {
ActionForward forward = mapping.findForward("success");
String path = forward.getPath();
path += "?foo=bar";
return new ActionForward(path);
}

But in this case, I'm not sure why you wouldn't just use a request 
attribute instead. By forward, perhaps you mean redirect?

Or, in a JSP link:
blah

RE: a technical question about using Eclipse with Struts (fwd)

[Martin Gainty]

hey Keith-
I would doubt the jar versions are changing unless of course your build 
process is un jarring all the jars and then re-jarring them later altho why 
eclipse would do that is beyond me-
sounds more like a config issue (by Eclipse) specifically what it is doing 
to server.xml and web.xml?
I would copy server.xml and web.xml  out to a 'safe' readonly folder and 
then copy back in before building the war

There was a similar problem for configuring SQLServer .. take a look at ..

Hi,
I can't seem to get the newest Struts-examples source code into Eclipse 3.0 
 in such a way as to generate a good .war file that can deploy to TomCat 
5.027.   The only public guide I see on how to set up struts in Eclipse is 
out of date.  This happens no matter which version /build of Struts I 
download.

I always get this exception:

RE: I suspect this is a bad idea...so what's a better one?

[Yee, Richard K, CTR,, DMDCWEST]

Joe,
Delegate the work that you are doing in your Action class to a service class
and think about using an ORM framework like Hibernate or Ibatis. Since the
service class will be local the Action, it will be threadsafe (unless you
use static vars in your service class or do something else that is unsafe).

Subject: I suspect this is a bad idea...so what's a better one?


I got tired of, in all my action classes, beginning with something to get a
database connection and at the end destroy it. I want to automate this a
bit.

Here is a first shot at what I came with: 

In my subclass of whatever flavor of Action I'm using, a have a protected
variable which holds my Persistence class object. My subclass implements
execute() such that it will instantiate the persistence object, assign it to
the protected class variable and call super.execute(), getting rid of the
connection afterwards. The action methods themselves just refer to the
protected class variable, rather than doing anything to generate/obtain it
itself. 

Now, I can only count on this working if, and only if, the Action class
itself got instantiated for the purpose of processing the request, and
destroyed afterward (otherwise the protected variable is going to get shared
between requests). Am I safe here?

If not, I suppose I could make it a ThreadLocal, but then I'd just be
replacing the create/destroy steps with a casting step. And since my goal
here is to try abd have all the work done outside of the "real" methods,
that's kind of self-defeating. Same holds true with using
request.setAttribute() instead. Ideally the persistence layer shouldn't have
to know it's in a web application, so I'd like to not have to pass in a
request object to it at any point.

Am I safe with my first guess? (I suspect not).  Failing that, what's a
better idea?

TIA

-Joe

-Basically what I have now is something like this-

protected Persistence persistence;

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
 HttpServletResponse response) throws Exception
{

 
 persistence = ActionHelper.getPersistenceObject(request);

 ActionForward result = super.execute(mapping, form, request, response);

 persistence.release();

 return result;
   }

I wish to forward to a action that require a url parameter.
request.setAttribute does not set a urlParameter in the style

How to set such a parameter, since request.getParameterMap().put() has

I think you and Craig are right. I might succeed with my goal of "firing (an
action) off and forgetting", but with creating a serious scalability issue
at the same time.  

Basically, I keep harkening back to one of my oft-repeated mantras: 

"If you write the same code more than once, make it into a method and call
it instead. If you call that method in too many places, find a better place
to call it from".

And I'm calling this one from *every* blessed action method. This _bothers_
me. 

So yeah, a filter is precisely what this idea is evolving into and Hibernate
even provides examples that do precisely this. Still the concept requires
code that explicitly gets the request object inside of each "real" Action
method, avoiding which is something I put (apparently way too much of) a
premium on. At least with the filter it's down to one line of code. 

So I can't declare the variable outside of my method. We all have our
crosses to bear :-)

Tx everyone.

I think so... one method one function. The setter should not do anything
other then set the variable, because that's what its name implies.  A
getter on the other hand implies that its going to get something, from
somewhere, that has a name.
My distaste for setters doing more then one thing is born of way to many
hours hunting down bugs that were the result of setter sideeffects.

Sounds like you really want a Filter that creates the persistence
object on the way in (storing it in a request attribute, so that it's
accessible in the Action.execute() method), and cleaning up on the way
out.

I would investigate very very carefully before I ever believed that a
persistence object could really be shared safely.

I would think long and hard about how you would ever shut down the
thread local persistence objects when the application shuts down.

I would wonder about why you'd be willing to have ThreadLocal
variables hanging around just because I happened to use that thread
once for a request, and might never do so again (either because it
killed the thread or because the number of concurrent requests when
back down from a peak).

Okay so what's wrong with a base action whose execute method then calls your execute 
method, but everything is setup.  Pass in the objects you've set up in a hash table 
for easy lookup.
Something like

blah execute( blah) {
//setup things
//put them in hash table
executeLogic( map, request, response, blah, setupStuff);
//close things whatever.
}

Except that you have just create a request scope variable ( one thread, one 
request)the painful way  When what you really want, it sounds like, is an 
application scope variable that you can get at.  
However, I think what you'll find is that you end up with a bottleneck on the 
persistance object, because you have multiple threads hitting it, which means that 
most of them will be waiting on the lock to be lifted.  This is why this particular 
problem  has never been solved, it creates a really nasty performance bottleneck.
Believe it or not it's actually cheaper to create and destroy the persistance objects 
on the fly then it is to make it thread safe because you will always have a lot of 
threads hitting the site.

RE: HTML:TEXT tag and Internationalization

>>you could format them yourself, either in the setter (yuck), or in the

Why not in the setter?  Sometimes I'll use the setter to populate some
other fields privately that then get used later on in the form.  Example: I
get a decimal number representing time off the db.  The setter moves left
of the decimal to an hours field and right to a minutes field.  Is this a
bad practice?

I want to be able to do alot of the mundane setup stuff that happens in
every action method without having to think aboout it.

Rather than having every method create and destroy a Persistence object, I'd
have an execute() method that created it, called super.execute() and
destroyed it.

The problem is getting this thing into the scope of the "real" Action
method. A class level protected variable to store the persistence object
seemed the best option, but it's not safe as it gets shared by every call
into the class. 

I could make the Persistence Object itself a ThreadLocal, but then I've
changed the creation step for a conversion step inside of the Action method.
Delegates have a footprint alteration to the current Action methods. *That*
seemed to me like over-engineering for this problem.

But If the Persistence class itself *is* threadsafe, then I shouldnt have an
issue, I figure if the Actions share them. Nothing but static public methods
and static ThreadLocal class variables. I really only need one or two class
level variables, and making them ThreadLocal isn't as gross of a change for
me. I'm just hoping a hole gets popped into the theory before rather than

This is the problem I'm having w/ the javascript validation in general.
The funcion name that's generated is not correct.  It puts the "/" from the
action path in the function name like this "function
validate/saveAuditAssignment(form) { ".  I don't know of a work around
other than going to a ValidatorForm or putting the javascript in the JSP
(I'll try the other suggestions).  I read at the Struts website that this
is resolved in 1.2 but I can't use it while it's in beta.

Thanks,

I'm picking this topic up again and actually, what I'm kicking myself for
just now occuring to me is this:

To recap: if I make my Persistence object a protected class level variable
inside of an Action subclass, it's not going to be threadsafe...

But...

If that class has only static public methods, and a static ThreadLocal class
variable for it's connection to the database, et al, then it should be safe
anyway.

Yeah, I'll have a type conversion for the ThreadLocal in each database
method, but not in every blessed action method.

One last sanity check? :-)

Then again, since html:text is usually used with a form bean, which is supposed to be 
all strings, you could format them yourself, either in the setter (yuck), or in the 
action.

Re: Date Validation

The commons-validator date validation indeed, can only validate a 
single date pattern.  Joe Hertz made a good point that you must have 
the multi-format parsing problem solved, so subclassing a 
ValidatorForm will probably be a good solution.

However, I don't understand your other comment:
I don't have the javascript validation available because I'm using
ValidatorActionForm.  It seems like my options are to switch to
ValidatorForm or code javascript in the JSP.
the javascript is independent of whether you are using 
ValidatorActionForm or ValidatorForm (don't worry, this is one of the 
things that confuses a lot of people.)  You can specify the action 
path in the  tag instead of the form name, and the 
javascript tag will work fine -- basically, html:javascript looks for 
the literal value from " in the Validator XML config 
-- whether it be a form name (ValidatorForm, DynaValidatorForm) or an 
action path (ValidatorActionForm, DynaValidatorActionForm).

Hope that  helps,

If you're talking about as parameters, then you can't.  If you're talking about 
session/request/application scoped variables then you can.  However, it sounds like 
you can't do that exclusivley, but you can mix the two.
So, your url would be something like 
http://blah/blah?key=someUniqueKeyThatIsNotTheSessionId that you use to pull the real 
parameters out of the session.  Because the key is only for the session, and unique to 
that session you can be reasonably sure that the request is from the session that was 
intially authenticated.  
The vulnerability here is that someone is able to get a legitimate users session key, 
and the unique key while the session is still valid.  If you're really paranoid, 
public key encryption of the unique key might even be possible, where the action that 
generates the link encrypts, and the action that performs the function decrypts the 
key before extracting from the session.
Generating that key would be fairly easy, depending on your definition of easy.. I 
would take a hash of the sessionId + timestamp + relavantInfo[1] and use that.

RE: Date Validation

[Joe Hertz]

Let me ask you this:

Presumably whatever the user enters is going to be used to construct a Date
object.

And if you do that, you presumably also know which of the various formats it
got entered in.

And if you have the logic somewhere to divine which format it's in, it
sounds like you have what you need to write your own validate() method to do
the job.

If you want to use the validator for your other validations, just make sure
you call super.validate().

Date Validation

[bmf5]

When I search the archive I get no results for the word "date" so here
goes.

I've been using the validation plug-in to validate the date format of
MM/dd/.  A new requirement is to allow the user to enter a date in one
of several formats(mmddyy, mm/dd/, and others).  Can the validator do
this or will I have to write my own validation?  I tried multiple
datePattern vars in the validation.xml but as expected only one worked.  I
don't have the javascript validation available because I'm using
ValidatorActionForm.  It seems like my options are to switch to
ValidatorForm or code javascript in the JSP.  Experienced opinions would be
appreciated as I'm learning as I go here.

RE: Exception Handler Help!

[Keith Bottner]

errors.do is an action mapping.

But your question made me take a second look at something. It appears that
the exception was getting caught and turned into an ActionError in a base
class and therefore never thrown outside the servlet, which of course
prevents it from using the global-exception. If I do remove this
functionality then the global-exception does work in all cases, whether
HTML, jsp or an action mapping (for those of you who are interested).

So thanks for all the help guys, the questions spawned the right thought
processes to track it down. I should have seen this sooner but 18hours
looking at the screen must have got to me, now to sleep.

Thanks again,

preventing direct access to action

[Dan Allen]

Normally we talk about preventing direct access to a JSP, but, in
contrast, have a question regarding direct access to an action. 
Consider the following scenario:

A portal application hosts several portlet modules.  Each of the
modules is passed certain parameters from the portal when the user
selects that module.  Some of these parameters determine the security
restrictions of the user (such as what components are visible to the
user).  However, if the user changes one of these GET parameters, the
user could exploit greater access.  Up to this point, a servlet filter
was checking that the "referer" field was non null.  I know that this
form of security is highly discouraged (as it can be faked).  How can
one be sure that the information passed from page to page can be
trusted?

My guess is that the advice given is that the parameter must be
validated against the database for the current user, not just trusted.
 In this case, the referer field is irrelevant.

RE: Tiles and well formed html

[Ruben Cepeda]

Andy,
I used s and they work fine.  Are you using pattern matching in you 
style sheet.

EXAMPLE:

#headerTile h1
{
 font-size: 400%;
}
#bodyTile h1
{

Subject: Tiles and well formed html
Date: Tue, 24 Aug 2004 10:27:19 +
Hi,
I have a trypical layout and each tile has its own style sheet and is well 
formed html.
My problem is that only 1 style sheet is being used for the whole page.  I 
saw in the mail archives that someone suggested using  tags but this 
doesn't seem to work for me (I've tried both in the tiles and in the 
layout.jsp).  Does anyone know what is considered best practice for this 
requirement.  It seems counter-intuitive to have your tiles not well formed 
html but if this is the solution which tile would you pick for the 'main' 
html tags or does it even matter?

Thanks,
Andy

Re: using struts and dbcp together throws sometimes a NoSuchElementException/SQLNestedException:

[Erik Weber]

Why not just close the connection if con != null && !con.isClosed() ?
I always:
try {
   if (rs != null) rs.close();
}
catch {}
try {
   if (ps != null) ps.close();
}
catch ()
try {
   if (c != null && !c.isClosed()) c.close();
}
catch {}
Not sure if that is it, but I don't understand your logic for deciding 
whether to close the connection. I am using Oracle with DBCP. I have a 
couple of properties set differently from you, but I don't see any that 
would be the problem.

HTML:TEXT tag and Internationalization

[hermod . opstvedt]

Hi

Is there any reasonable argument as to why the html:text tag uses
default (value.toString()) formating, while the bean:write uses a
formatter that is I18N aware. This is really anoying for locales that
normally use comma as a decimal seperator. If you output the value with
bean:write it will look OK, but displaying it in an html:text it will
use the English dot as a decimal seperator. I think that moving the
formatValue from WriteTag into TagUtils, hence making it avaiable to all
tags would be a good idea. Then we would have a uniform formatting of
values.

Is using forward as an exception handler's path valid? I didn't know you
could do that.

Anyway, I'd reduce the complexity of what you are doing: Start by using an
html page as your path, then try a JSP, then an action.

Exception Handler Help!

[Keith Bottner]

Configuration of global exceptions looks very simple. So I cannot understand
why the configuration of my global-exception refuses to pick up any
exceptions. If an error occurs I just get the blank white page. Here is my
global-exception configuration section.



 

Then I have a global-forward that looks like this



I tried specifying /errors.do as the path for the global-exception and that
did not work either. Any ideas on why Exceptions may not be getting routed?

Thanks,

Keith

Re: Emulate a modal screen (Struts newbie)

[Erik Weber]

Perhaps the J2EE pattern "Use a Synchronizer Token" could be of use or 
even be a complete solution. Struts has built-in support for this in the 
form of several Action methods (such as isTokenValid(HttpServletRequest) 
-- which checks to see if the value of a "timestamp" stored as a session 
attribute is equal to the value of a "timestamp" that was enscribed in 
the last-issued HTML form as a hidden parameter).

I have used identifiers + timestamps (the timestamp can be just a random 
String) with my form tokens, so that I know if a submitted form is the 
one I expect, not only in terms of chronological ordering, but with 
respect to *the relevent actor*. If a user "checks out" a FooEdit form, 
then a BarEdit form, then submits the BarEdit Form, then tries to submit 
the FooEdit form, he will violate what the simplest of token-checking 
schemes would allow (the FooEdit token in the user's session would have 
been replaced by the BarEdit token at form checkout time). But 
obviously, he has followed proper workflow when you consider that two 
different *actors* were involved.

I don't know if Struts has any support for "complex" form timestamps, or 
in other words, multiple form tokens as simultaneous session attributes.

Hope that helps.

Tiles and well formed html

[andy wix]

Hi,
I have a trypical layout and each tile has its own style sheet and is well 
formed html.
My problem is that only 1 style sheet is being used for the whole page.  I 
saw in the mail archives that someone suggested using  tags but this 
doesn't seem to work for me (I've tried both in the tiles and in the 
layout.jsp).  Does anyone know what is considered best practice for this 
requirement.  It seems counter-intuitive to have your tiles not well formed 
html but if this is the solution which tile would you pick for the 'main' 
html tags or does it even matter?

Thanks,
Andy
