RE: How To Handle Mis-Typing of URL By Users

[David G. Friedman]

Jen,

The question is are you trying to catch mistyped Struts URLS OR regular URL
resources such as JSPs, HTML, CSS, Javascript includes, Images, etc.?
For the former, you're barking up the wrong tree (see below).  For the
latter, your error-page code should work UNLESS those file types are NOT
being handled by your Java Server (perhaps locally by a front-end Apache?).

Some key documentation (uh, oh, I'm saying RTFM aren't I? LOL):
http://struts.apache.org/userGuide/building_controller.html#actionmapping

It explains a wonderful struts-config.xml Action Mapping feature:

unknown - Set to true if this action should be configured as the default for
this application, to handle all requests not handled by another action. Only
one action can be defined as a default within a single application.

So, if your URL is defined as http://www.yoursite.com/myapp/someAction.do
but the visitor ended up typing in a Struts URL you never configured in your
struts-config.xml file(s) such as
http://www.yoursite.com/myapp/someFraction.do, this struts-config.xml
mapping would catch it and other Struts URL mistypings:



And yes, I have used the "unknown" parameter at least once in a Struts v1.1
deployment, though not recently.

Regards,
David

Hi, I prepared the error404.jsp (simply typed in a
warning sentence) and placed the file in the
AppName/WEB-INF/web.xml file this way:

  
index.jsp
  
  
404
/error404.jsp
  
  
  
 /tags/struts-bean

/WEB-INF/lib/struts-bean.tld

  

I tested mis-typing.  But, my sentence; i.e. the error
page that I prepared does not show up.

Would you be more clear about "map this condition
directly to a Struts action or URL mapped directly
to a servlet." in the servlet 2.4 environment?  I
still do not have any idea about how the mapping
should be done in the struts-config.xml file.

RE: JTidy integration?

[Nestor Boscan]

Hi

I have not used Struts with Jtidy but I've used the two technologies in
different projects. The way I see it you create a servlet filter that uses
the Tidy.parse method to parse the JSP output. Then you map the filter to
the main JSPs that includes the rest of the content. Everytime the
controller forwards or redirects your actions to the JSPs the servlet filter
will activate and pretty print the content.

Hope this helps

Asunto: JTidy integration?

Has anybody integrated JTidy or any of the other HTML-prettifiers with
Struts?  I find Tidy does a good job of cleaning up JSPs, which tend to get
pretty spaced out particularly when there are lots of includes, but I don't
have a clear idea of where it would plug in.   Would it make sense to put it
into a servlet filter and then chain that onto the Struts controller
servlet?  Or is there a logical spot to put that functionality somewhere
inside the framework (attach to an action or something??).  Or would it be a
plug in?

Thoughts?

Re: [OT] Apache/Tomcat restriction by IP address

[Erik Weber]

Thanks Niall.
The problem is, some stuff is served out of Apache's doc root, while 
other stuff is served by Tomcat. I am hoping to find a central place to 
install the IP restriction.

The valve won't restrict what is in Apache's doc root, and the .htaccess 
file won't restrict what is dispatched to Tomcat (I think .htaccess is 
at the file/directory level, and I need it at the URL level). However, 
.htaccess combined with valves seemingly would do the trick. I haven't 
tried it yet.

If anyone knows how to configure it all in Apache though, I would 
appreciate a tip. I think it might be done in httpd.conf, but I'm still 
trying to figure it out. Plus I have the problem of figuring out the 
nuances of the third-party hosting environment (for example, there *is* 
no httpd.conf :/).

Thanks,
Erik

I have a site running on a third-party box that uses Apache in front of

Using the Deny, Order and Allow commands in a .htaccess file works for
whatever is in Apache's public document root. However, it doesn't

For example, if I forbid my own IP address with this:
Deny from xxx.xx.xx.xxx
I cannot access anything in Apache's document root, but I can still

dispatch *.jsp to Tomcat).
How can I tell Apache to filter *all* requests by IP address?

Re: Idea for chain and DB transactions

[Sean Schofield]

Robert,
Thanks for the feedback.  I took a look at Spring.  It seems interesting but 
I decided to pass on it right now rather than take the time to get up to 
speed on yet another framework.

I did take a look at ThreadLocal, however, and I think this will be perfect 
for what I need.  In fact I found an article that describes how to use 
ThreadLocal and uses JDBC connections in one of their examples 
(http://www-106.ibm.com/developerworks/java/library/j-threads3.html).

I had hear people mention ThreadLocal before but I never really knew what it 
was about.  Now that I've taken a look at it I'm pretty impressed.  It was 
interesting to learn that the initial implementation of ThreadLocal was very 
similar to what I was proposing here.  (Apparently, It has since evolved to 
be much more efficient than the initial implementation.)

I'm allways glad to check with others before embarking on a solution like 
this.  Often times I am on the right track but the collective experience of 
programmers can usually come up with a superior solution (much like Struts 
vs. my own efforts before discovering Struts.)

Thanks again!
sean

Sean, have you looked at Spring? It uses AOP and you can set up 
transactions declaratively.

I'm just starting to investigate using Spring and I'm really impressed.
Like you I had a requirement to demarcate transactions at a high level so 
that
all business objects within the transaction were subject to the same 
transaction
semantics unless a business object explicitely needed to be isolated.

I ended up creating a Transaction framework of sorts which uses 
ThreadLocal to
propogate the Connection to my DAO's. All DAO's that need to be included 
in a
transaction had to subclass a TransactionalDAO which "knew" how to access 
the
current TransactionContext from ThreadLocal.

It has worked for a couple years now, but its not that clean or elegant.
That's why I was so excited to read about Spring and IoC.  It does all 
that stuff
for you.

Subject: Idea for chain and DB transactions
I have a problem and a proposed solution.  I would greatly appreciate any 
feedback about the proposed solution.

Problem:
===
I'm currently using a Struts application with a connection pool (using 
DBCP as supplied by Tomat).  When a database
update is needed, the Struts actions will call the facade which will talk 
to my service layer (currently POJO's which
handle business logic.)  My service layer in turn talks to the 
appropriate DAO.  Each of these DAO's extends from a
common abstract class that provides basic functionality including 
obtaining a connection from the DataSource (via the
pool).  A key aspect of my design is that some updates are in distinct 
areas of the database and so I have different
DAO's for each area (ex. one for "workflow" on for "document.")

As currently implemented I am unable to take advantage of transactions 
because the two DAOs will be getting a connection
indepently from the pool and they will most likely not obtain the 
connection each time.  If I could just get the same
connection each time, then I could use setAutoCommit(false).

Proposed Solution:
==
I'm thinking I could set up a few chains for the various kind of updates. 
The chains would be called by the POJO service
layer (instead of calling the DAO's directly.)  The first Command in the 
chain would be to indentify all database updates
in the chain as needing transactions.  This would be done through a 
static method on a new object called
TransactionManager.  Basically I would have a hashtable that would 
maintain connections for the duration of the chain.
The connections would be stored by the current thread (use that as the 
key to the table.)

Then when a command down the line needs a database connection, it would 
first check to see if there is one already set
aside for it to use.  Actually the command would call the DAO and the DAO 
would check.  The command would also be
decorated by a custom wrapper so that if the DAO's try to close the 
connection, I'll ignore it.  Then when the chain does
the post processing in reverse order.  So the last clean up step will be 
to check for my custom DAOException.  If there
is one, then rollback, otherwise commit.  Finally, the connection is 
removed from the TransactionManager.

I think this might be crazy enough to work.  I know we could allways use 
EJB and get transactions but that might be
overkill since the volume is very light (this is custom software for a 
government agency not ecommerce.)  Please let me
know what you think.  A big question I have is about storing and 
retrieving the datbase connect

I had thought about this but it involves duplicating each DAO method.  Also
if I ever wanted to switch to EJB I would have to undo all of the methods
again.  Its definitely an option though.  I was just hoping for something
that would involve less changes to my DAO's.

Thanks for the feedback.

Hi,

After reading the email archives and the documentation, it is clear that
the  tag cannot be used with a module attribute and a page
attribute at the same time. I was just wondering why this is? Is there a
strong reason this was not implemented, or is it just a piece of missing
functionality?

SAX parser anomaly

[Woodchuck]

hihi all,

has anyone encountered a SAX xml parsing error due to some
property/attribute of a physical file?

i'm getting that right now.  an xml file created by a legacy VMS system
is causing SAX parsing exceptions.  BUT, if i copy and paste the
contents of that file into my own file, i don't get any parsing errors
at all!

has anyone experienced this?

when doing a file comparison between these two files, they are exactly
the same.  i even looked at them using a hex editor and there are no
differences (ie. no invisible characters differences).

but, there must be a difference!  because when i copy and paste the
contents to a new file, that new file does not cause parsing errors. 
if i try to parse the original VMS created xml file, it causes errors.

so there is something different between these two files

anyone have any clues at all how i can find out why the anomaly?

thanks,
woodchuck

After thinking about the flavors of Dispatch actions I use, and after

modular self contained Actions.

My question is more of design practice for those that just use standard
Actions. How do you design your packages? For example...

EmployeeUpdateAction:

1) package com.acme.ui.action.employee;

or

2) package com.acme.ui.employee.action;

or just put them all in one package:

3) package com.acme.ui.action;

I'm leaning towards option 1 myself. Other thoughts?

Why not write an InitServlet that is set to initialize prior to the struts
ActionServlet in web.xml?  This could override the init() method and provide
the services you need.

>From web.xml

  
init
com.xxx.xxx.servlet.InitServlet

Then your init() method could have something like:

in a properties file or source file instead of web.xml).

For example:

form.getServlet().getServletContext().getAttribute("smtpServer");

RE: Idea for chain and DB transactions

[Robert Taylor]

Sean, have you looked at Spring? It uses AOP and you can set up transactions 
declaratively.

I'm just starting to investigate using Spring and I'm really impressed. 
Like you I had a requirement to demarcate transactions at a high level so that
all business objects within the transaction were subject to the same transaction
semantics unless a business object explicitely needed to be isolated. 

I ended up creating a Transaction framework of sorts which uses ThreadLocal to 
propogate the Connection to my DAO's. All DAO's that need to be included in a 
transaction had to subclass a TransactionalDAO which "knew" how to access the
current TransactionContext from ThreadLocal.

It has worked for a couple years now, but its not that clean or elegant. 

That's why I was so excited to read about Spring and IoC.  It does all that stuff
for you.

RE: I'm going back to just using regular Actions.. a question

[Robert Taylor]

Yep. I usually bunch all action type stuff in the action package.
Like forms, action utils, value objects used in actions, etc...
I guess it more or less represents the presentation part of the package
and the service represents the business part. I only see a need to dissect
it into these two because the actions should only need to talk to the 
service layer. The service layer should be talking to reusable components
in some other package like com.acme.components.whatever.

Re: Idea for chain and DB transactions

[Sean Schofield]

I had thought about this but it involves duplicating each DAO method.  Also 
if I ever wanted to switch to EJB I would have to undo all of the methods 
again.  Its definitely an option though.  I was just hoping for something 
that would involve less changes to my DAO's.

Thanks for the feedback.

Problem:
===
I'm currently using a Struts application with a connection pool (using 
DBCP as supplied by Tomat).  When a database update is needed, the Struts 
actions will call the facade which will talk to my service layer 
(currently POJO's which handle business logic.)  My service layer in turn 
talks to the appropriate DAO.  Each of these DAO's extends from a common 
abstract class that provides basic functionality including obtaining a 
connection from the DataSource (via the pool).  A key aspect of my design 
is that some updates are in distinct areas of the database and so I have 
different DAO's for each area (ex. one for "workflow" on for "document.")
As currently implemented I am unable to take advantage of transactions 
because the two DAOs will be getting a connection indepently from the pool 
and they will most likely not obtain the connection each time.  If I could 
just get the same connection each time, then I could use 
setAutoCommit(false).

Proposed Solution:
==
I'm thinking I could set up a few chains for the various kind of updates. 
The chains would be called by the POJO service layer (instead of calling 
the DAO's directly.)  The first Command in the chain would be to indentify 
all database updates in the chain as needing transactions.  This would be 
done through a static method on a new object called TransactionManager. 
Basically I would have a hashtable that would maintain connections for the 
duration of the chain.  The connections would be stored by the current 
thread (use that as the key to the table.)
Then when a command down the line needs a database connection, it would 
first check to see if there is one already set aside for it to use. 
Actually the command would call the DAO and the DAO would check.  The 
command would also be decorated by a custom wrapper so that if the DAO's 
try to close the connection, I'll ignore it.  Then when the chain does the 
post processing in reverse order.  So the last clean up step will be to 
check for my custom DAOException.  If there is one, then rollback, 
otherwise commit.  Finally, the connection is removed from the 
TransactionManager.

I think this might be crazy enough to work.  I know we could allways use 
EJB and get transactions but that might be overkill since the volume is 
very light (this is custom software for a government agency not 
ecommerce.)  Please let me know what you think.  A big question I have is 
about storing and retrieving the datbase connection using the current 
thread as the key to a hashtable.  Also, I know that I will have to be

Re: I'm going back to just using regular Actions.. a question

[Frank W. Zammetti (MLists)]

Yes, that's exactly what happens.  I understand your approach, even like
it!  :)

I think what it comes down to is do you break things up in an
object-oriented way or a functional way?

It can be argued that done as you say, you are breaking it up based on
objects, which mimics how we generally develop nowadays, so it makes
sense.  On the other hand, my approach indicates that all the classes in
the actions package serve the same general functional purpose.

I'm not sure either is more correct in any way than the other... I
personally find it easier to work on a project when I don't have to flip
between a large number of directories (or, in a related kind of way, a lot
of classes).  I'm kind of old-school in this regard... The more of a piece
of code I have right in front of me in one place, the better.  This is
largely contrary to OOP ideals, and sometimes I have to fight myself to
NOT do what feels natural after so many years :)

RE: I'm going back to just using regular Actions.. a question

[Robert Taylor]

Rick, 

I have been using the following package layout for a while and it seems to make sense.

For example, let's say the foo web application consists of various sub applications 
like
account, store, product download, etc


com.acme.applications.web.foo.account.action
com.acme.applications.web.foo.account.service

com.acme.applications.web.foo.store.action
com.acme.applications.web.foo.store.service

etc...


May not be the best way, but like I said, it seems to make sense and it works for me.

Re: I'm going back to just using regular Actions.. a question

[Frank W. Zammetti (MLists)]

I personally use #3.  In fact, all my projects have a pretty
internally-standard packaging scheme (my own creation)...

com.company.project
 |
 *---actionforms
 |
 *---actions
 |
 *---business
 |
 *---config
 |
 *---daemonthreads
 |
 *---exceptions
 |
 *---listeners
 |
 *---plugins
 |
 *---webservices

actionforms and actions are self-explanatory, business is any business
delegate class (i.e., anything specific to the app but not tied to the
presentation), config is any app-specific configuration classes,
deamonthreads is any background threads, exceptions is any custom
exception classes specific to the app, listeners are any HTTP listeners,
plugins are any Struts plug-ins and webservices is any Web Service-related
code.

All but the first two are optional in any given project.  Any class that
is shared with other projects in is com.company (possibly in a package
underneath that).

It's just what I've settled on... Works for me.

I would write a Struts Plug-In (very easy) and initialize the 
"smtpServer" variable (and similar variables) there, making the 
configured value available to the rest of the application (including 
your Actions) by setting an Application scope attribute (this also 
abstracts the configuration so that in the future you might configure it 
in a properties file or source file instead of web.xml).

For example:
form.getServlet().getServletContext().getAttribute("smtpServer");

I'm going back to just using regular Actions.. a question

[Rick Reumann]

After thinking about the flavors of Dispatch actions I use, and after 
having used them as my primary type of Actions for the past 3+ years, 
I've decided to go back to just using regular Actions. I like the 
modular self contained Actions.

My question is more of design practice for those that just use standard 
Actions. How do you design your packages? For example...

EmployeeUpdateAction:

1) package com.acme.ui.action.employee;

or

2) package com.acme.ui.employee.action;

or just put them all in one package:

3) package com.acme.ui.action;
I'm leaning towards option 1 myself. Other thoughts?

input parameter not context relative?

[Dave Bender]

Isn't an Action's 'input' parameter supposed to be context relative?  
I thought that it was supposed to be, but I'm seeing otherwise when 
my form, which is in a module, fails its validation test.

Instead of returning to the input form, it is forwarding to the input
form prefixed with the module name.   In my profile-config.xml file, 
which configures the module, I have this  Action:


  



When I fill in the form correctly, the request gets forwarded on to 
the next form, email.jsp, which is located in /jsp/pages/profile.

But if it fails validation, it is getting sent to 
/profile/jsp/pages/profile/index.jsp, which doesn't exist, which pops
 up an error message. 

Here's the log file output, which seems to confirm the problem:

-  Validation failed, returning to '/jsp/pages/profile/index.jsp'
-  Delegating via forward to '/profile/jsp/pages/profile/index.jsp'


How do I get around this?  Many thanks in advance.   I really 
appreciate the help I've gotten from folks on this list.

RE: Struts Taglib Question

[ravi.vedala]

If you want to have a default value, simply set the default value in the form bean.

Eg :

XYZForm{
String name = "Ryan";

public String getName(){
return name;
}
public String setName(String name){
this.name = name;
}
}

Subject: Struts Taglib Question



Hello,

Is there some sort of Struts tag that I can use to set the property of a bean?

I have a small fragment that I want to look like this:


<%-- Set the event.date property on formBean to a default value --%> 
  .


It says that "if the event.date property on formBean is an empty String then set it to 
a default value."  I want to do it because I want the following select tag to have a 
specific default date selected instead of a random one being the deault select.

I just want to be able to set the event.date property to a default value if it's 
already an empty String.  I'm looking for a tag to do it because this JSP page is 
generated via XSLT from another XML document, and there could be many bean properties 
that need to be defaulted.  I want to be able to preserve the use of the dot notation 
for nested parameters.

Basically, I want a tag something like this:



Is there any way I can do this?

Thanks!!

I am forwarding to a page containing and html:form with radio buttons

tiles-definition - role association issue

[Ashutosh Satyam]

As per the Tiles Definition file syntax
 In the tiles definition we can specify the role 
 (Role to be checked when definition will be inserted in a page.)
  
Similarly, It is possible to associate a role with tiles: put attribute.

I'm intending to allow the definition to be used based on the role.

The second scenario works fine for me.
I have my Login page for the application as stated below.

<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>











Depending upon the user's role, correct definition is inserted.

Now going on the same lines, when I have a definition with role specified, it  
doesn't seem to work. My tiles-definition is as follows.












 

This definition (Add) gets applied for each of my role, though I was presuming that
only for the user with 'admin' role this definition will be executed.

What am I missing? Is it not a correct approach?
Kindly give some solution to achieve it.


Regards,
Ashutosh

Re: Validator - Browser Compatibility Issue

Hi,
We have upgraded to Struts 1.2.2 , but we have encountered a problem. Embedded

var fields = new Array();

However, getAttributeNode is compatible with IE6.0+. Still many clients use IE5.0 &

Regards,


Seyhan -
This is probably something you need to ask on the commons/validator user 
list and not on the struts list.

From what I remember, this change came about because of the new 
"multiple forms on the same page" feature of validator. The original 
patch used the form.name property, but that messed up if you had a form 
element with the name of "name". The options to fix that were to use 
getAttributeNode or a big nasty loop through the form elements, and 
getAttributeNode was chosen.

I would say this isn't a huge problem though, for 2 reasons. The first 
is that the purpose of using vaildator is that you have client and 
server side validation. In addition to that, most "browser statistics" 
sites put IE5.5 (and lower) as being less than 10% of usage. You would 
be doing a lot of work to support a very small population if you wanted 
this "fixed".

Also, just FYI, Struts 1.2.2 is not a good version to be using. It is 
probably best if you upgrade to the 1.2.4 build from the struts 
acquiring page. (not the downloads page!)

yes, it is my understanding that the plug-in needs to be defined in
the module you are working with.  so if you are using more than one
module you can validate some and not have to validate all by only
including the plug-in in those modules that you want validated.

looking at the error you're getting my first guess would be that the
page you are executing does not have the field listed in your
validation.xml.

also, look in your struts-config where you've defined your action.  do
you have validation="true" set for that action?

is your formset wrapped in ?  or do you have
 as your root tag in the validation.xml?  i would guess that
this would give you a different error if you had the wrong root... 
but worth a look

"Resources not defined for Validator"

I'm having a challenge getting the Validator plug-in to work.   It's my first crack at

Struts Taglib Question

[Asleson, Ryan]

Hello,

Is there some sort of Struts tag that I can use to set the property of a
bean?

I have a small fragment that I want to look like this:


<%-- Set the event.date property on formBean to a default value --%>





It says that "if the event.date property on formBean is an empty String then
set it to a default value."  I want to do it because I want the following
select tag to have a specific default date selected instead of a random one
being the deault select.

I just want to be able to set the event.date property to a default value if
it's already an empty String.  I'm looking for a tag to do it because this
JSP page is generated via XSLT from another XML document, and there could be
many bean properties that need to be defaulted.  I want to be able to
preserve the use of the dot notation for nested parameters.

Basically, I want a tag something like this:



Is there any way I can do this?

Thanks!!

RE: DynaActionForm and previous request attributes (no answer found in archives for similar problems)

[Allistair Crossley]

not quite .. when i arrive initially at the view governed by somePage.jsp yes, there 
are a bunch of request attributes set up. on this page is my form. as a hidden 
variable to the form I copy the existing page id because this must be present for our 
SecuredBaseAction to know what properties to load into the "new" request. 

what i see as completely possible and useful is that for a DynaActionForm action's 
input="somePage.jsp" attribute, to use input="anActionExtendingSecuredBaseAction.do" 
so that when validator fails the form, it can call the action which can make sure to 
lookup the page id from the dyna form, query the backend for the attributes, whack 
them into the request and then return a view.

do you see what i mean :))

RE: DynaActionForm and previous request attributes (no answer found in archives for similar problems)

[Allistair Crossley]

when i submit my form to the action, the action maps my form to a DynaActionForm and 
binds the values. 

now, along with my form, i actually do submit something called PID (page id) which is 
the current page at time of submission. therefore, my dyna form will have the page id 
for which i need to load navigational information. 

however, because I am forced to use a tile definition or JSP in the input parameter of 
the action for when the validation fails, i am unable to load page attributes for that 
pid from my backend navigation system and this is breaking my view.

now you might say that all i need to do is load the page attributes from the jsp 
because it will be in the dyna form when i get to the view after failure, but now we 
are talking about breaking the whole point of MVC as i would need to call my backend. 

can anybody see what i am getting at here?

Re: Invalidating the session

Hello,

You can create filter for the login page.
That filter should disconnect the user of the web application (if exists).
All users that access login page, will be forced to be authenticates again.
If problem persist, it could be web cache.

You can put JavaScript on every page that will attempt to send the browser
to a specific url when the browser is closing, but that would be browser
specific and it is VERY likely that your action will never get called for
most users.  This is the web, if you want that feature you will need to go
rich client.

Re: file data source

[James Mitchell]

You would need a JDBC driver that supports file based storage.  You are
better off using HSSQLDB.  I can help you with that.

Hello world,


Maybe, it's not designed for that, but i wonder if i can
use   struts conf to access a local
file system (file://...) ?
I know this request is a bit strange, but it's for a very
temporary solution. No sql server available for the moment ...

Is it possible?
If so, where should i get some clue to make it work?

Don't shoot me if I'm wrong but HTTP is stateless so without any of:
cookie, session, browser politeness (HTTP referer), hidden field with
url, server won't be know where you come from (and in request scope
you will won't have any information where user was before clicking
Submit) ...

RE: DynaActionForm and previous request attributes (no answer found in archives for similar problems)

[Allistair Crossley]

what I have already described in some detail. the use of base actions is a good 
pattern to use as one can group common behaviour into them, such as authentication or 
ensuring other properties. in our case we do both, security AND ensuring some session 
lists for user (i.e those things that make sense to be in session because they don't 
change often at all for the lifetime of a user's visit) but also request attributes as 
I said .. the user clicks a nav link, that page's attributes get loaded as a map, and 
do not make sense to be in the session because it is per-request object.

now, my issue with DynaActionForm is that it ought to relise that if it has to forward 
the user page to the page they came from, it ought to also forward the request values 
back, OR at least be able to give you the opportunity to specify an Action rather than 
an ActionForward as the input parameter so that we can ensure those request vars are 
present for the view.

managing a request attribute in the session by setting it and then making sure we pop 
it out at the view is messing and defies the semantic use of the request scope.

that's why it is bad practice.

I think you are confusing what is happening here.  If I understand you
correctly, you are setting thing into the request, then forwarding to a
"somePage.jsp" page.  When the user submits that page, and the validator
fails, the request is forwarded to the input="somePage.jsp" of that action
mapping.  And you are wondering why those attributes you set in the first
request are not there for the second on?

Am I understanding you here?

If yes, then you should know that those are 2 separate requests.  If you
rely on some collection to be in the request for use with a select box, that
collection won't be there if the validator fails.  As I understand it, you
don't want to store thing in the session.  That's ok, there are many
different approaches to get around this.  If you ask 5 developers, you'll
likely get 6 different answers.  You should Google it, and/or buy a book.  I
would recommend that new one coming out by O'Reilly.  Bill Siggelkow is one
smart cookie (when sober ;).

Hi All,

I am coming up against a limitation of using DynaActionForm that I wonder if
someone can confirm or deny.

All our Action classes extend a SecuredBaseAction. This SecuredBaseAction
does a few important things per request like making sure the user is
validated and also loading page properties matching a page id that is
assigned to each request so that when the Action returns the view, that view
is able to do stuff like build the navigation and a range of other things I
won't bore you with. This is an intranet system therefore navigation needs
to be present at all times and so on.

This is a per request attribute and so it should be.

Now, I am building a validator-based application that sits within this
intranet framework. I do not want to get into ActionForms as they are a
ball-ache but I do like the validator framework, so I want to use
DynaActionForms.
I have setup my first form and have it validating without an issue. However,
there is an issue because when I get my input view back following a failure,
all my request attributes are gone from the previous request and because I
have to send a forward, my nav attributes and so on cannot be reloaded. This
is causing errors.

Now, my understanding was that DynaActionForm manages to populate a map of
form fields, match them up against validation rules, and if it fails, it
would KEEP the previous request but add errors into it and FORWARD back to
the view, therefore KEEPING all the request attributes. It does not appear
to work in this manner and I am confused.

A similar post I found suggests using SESSION but this is not only poor
practice but impossible for the operations we need to perform per action.

Any comments are greatly appreciated else I am going to have to scrap using
validator which I don't want to do.

Cheers, ADC.

Please tell me Y are you using the shaded code when the classes being used 
are depricated.

If i use this:

   


 i get no message in my jsp file.

 Once Again my Actionclass says:
ActionMessages messages = new ActionMessages();
errors.add(ActionErrors.GLOBAL_ERROR, new 
ActionError("error.mitarbeiter.anlegen"));
saveErrors(req, errors);
I guess it might be saying
   messages.add(ActionMessages.GLOBAL_MMESSAGE, new 
ActionMessage("error.mitarbeiter.anlegen")).

OK the next thing is: Can I c your struts-config.xml once?

I would try this:

I dont know if it works, since I have no way now to test it...


You have to find somewhere value of GLOBAL_ERROR and then it is easy, i
think.

[Jitender K Chukkavenkata]

use  tag or  tag for accessing messages in the 
same way as you use  tag.

Accessing ActionMessages in a jsp-File!

[Manuel Wissmann]

Hi Everbody!
I've got the following problem:
In my MitarbeiterAction.java   I've got the following Code:
...
public ActionForward execute(ActionMapping mapping,
   ActionForm form, HttpServletRequest req,
HttpServletResponse res) throws Exception
{
  ActionMessages messages = new ActionMessages();
 
   MitarbeiterForm mf = (MitarbeiterForm)form;
   Mitarbeiter mitarbeiter = mf.getMitarbeiter();
   mitarbeiter.anlegen();

   // checks if  Mitarbeiter  exists in the db
   if( 
!mitarbeiter.checkMitarbeiterExists(mitarbeiter.getStammNr()) )
   {
   errors.add(ActionErrors.GLOBAL_ERROR, new 
ActionError("error.mitarbeiter.anlegen"));
   saveErrors(req, errors);
   }
   else
   {
   messages.add(ActionMessages.GLOBAL_MESSAGE, new 
ActionMessage("mitarbeiter.angelegt"));
   saveMessages(req, messages);
   }
return mapping.findForward("MitarbeiterCreated");
}
...

My Question is now,  How can I access the ActionMessages in the jsp to 
which the Action is forwarded???

THX

Re: Posting XML to Struts

[Martin Schaefer]

The code snippet below uses JDOM but should easily be adaptable to
anything else. Hope it helps. On the server side read the data from the
request's inputStream. If however you want to use multipart messages
things get slightly more tricky.

URLConnection conn = ...

// configure the connection

conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);

// output the document into a byte array output stream

ByteArrayOutputStream outputStream = new
ByteArrayOutputStream();
PrintWriter outputWriter = new PrintWriter(outputStream, true);

XMLOutputter outputter = new XMLOutputter("  ", true,
"ISO-8859-1");
outputter.setTextNormalize(true);
outputter.output(requestDocument, outputWriter);
outputWriter.flush();

// set the header fields

conn.setRequestProperty("Content-Type", "text/xml");
conn.setRequestProperty("Content-Length",
String.valueOf(outputStream.size()));

// write the data to the request body

outputStream.writeTo(conn.getOutputStream());
}

Re: Accesssing the multiple MessageResources

[Honza Spurný]

I've found it out! So simply and It wasnot clear to me!

I'm sorry for this question, since it is so easy:

When You specify additional resources, such


so You can sipmly access whole MessageResources class by for example in JSP:


So the key to access the whole class equals (is the same) as the bundle key!
Simply.

Sorry for my stupid questions...

Best Regards

[KhayOng]

In the action class, just call request.getInputStream().

Re: problem in db access

[Bj]

you can do this in several ways but you always need to reload the JSP 
page and use a bit of javascript.

If you fill your combobox in the JSP, then simply reload the page with 
an additional request parameter containing the selected option. In your 
JSP code you must check the presence of this parameter and fill the 2nd 
combo calling your DAO layer.

If your fill your combobox in your Action and with Struts iteration 
tags. Submit your form to your action on the onChange of the 1st 
combobox. Then you will fill the corresponding ActionForm field and 
forward to your jsp.

 hello friends,
 
I have a form in a jsp page, where i have 2 select box .
The values of both come from the database(db). 
On the selection of first select box, the values should be fetched from 
the database for the second on the  basis of the value selected in the 
first.
 
When i load the page i call a action and then access the db with the BO  
and the DAO. Now how do i access the db from the jsp page and retain the 
value selected in the first select box.
 
 
eg
 
country<>
 
states<>
 
on the basis of selection of the country  select box, the stated select 
box should be populated.
 
 
 
Thank you all in advance.

Hi there,

thanks for hint. This should work, there's no problem probably in it. Only
think I can see on first view is, that this method is deprecated - this is
still not the biggest problem, but this will return only one message. What I
need more is to get whole MessageResources class.

But thanks for hint. This is usable in limited number of cases I need it to
use. (but it's a step forward for me :)
