fill combo box based onClick of previous combo box

[R.Vijayaraghavan]

Hello,

I have an application where I have 3-4 combo boxes. After selecting a
particular value from the first combo box, the second combo box should be
filled with values from the database. Likewise for other combo boxes. How
can this be implemented in Struts.

Will this be feasible:

Call form.submit on combo box's onClick, then get the value in Action, go to
the Model, get the corrosponding values, fill the form bean in Action class
and open the same page.

regards,
vijay.

Cannot create iterator for this collection

[Tony Smith]

Hi, I am using struts taglib. I have a object like

public class myObject{
List myList;

List getList(){
return myList;
} 

...
}

The myObject is send through aciton to the jsp. In my
jsp, I have:

...


...


But it complains that " Cannot create iterator for
this collection" which means myList is not reconginzed
as a list.

What is wrong?

Thanks,

qq

[OT?-ANN] Article on "Eclipse goes ServerSide - from RCP to RSP"

[Wolfgang Gehner]

I've just posted an article on a fairly new way to build web 
applications with Java (including Struts, in tandem with other 
technologies).

The article is at
http://www.infonoia.com/en/content.jsp?d=inf.05.07
It is also discussed at theserverside.com, and eclipsezone.com, since it 
also involves the Eclipse community.


Enjoy!

Re: error messages doesn't appear if validate is called programatically

[Paul Benedict]

Hakan,

You need to store the error messages in the request or session after you 
retrieve them:

ActionErrors errors = form.validate();
if ((errors != null) && !errors.isEmpty()) {
  saveErrors(request, errors);
  return mapping.getInputForward();
}

error messages doesn't appear if validate is called programatically

[Hakan . Barisik]

Hi,

I  have started using struts recently.

 I  don't want to use default  validation checking  so I changed 
struts-config.xml. 

.
.
0 )
  // forward to input page



In auto validation case ( validate="true") error messages I configured 
appears on Input JSP
but if  validate="false" as I configured above then messages soesn't 
appear on the Input JSP. 

Could  anyone point me to some documents or provide hint  about this 
problem?

Thanks and regards

Hakan

play with Clay right now. What do I need to do?" At least for a new 
comer to Shale. For instance, my problem was that I stripped out 
everything I didn't think I needed. From what I understood 
commons-chains was mostly being used for the remoting support so I 
removed it from the web.xml and got rid of the configuration. It was 
only because of your description of the stack above that I dug a little 
deeper and found that commons-chain is needed by some core parts of 
Shale, and is especially important for Clay.


So, I now have a working simple Shale Clay setup with just a single file 
that I can start to explore with and find out what Shale Clay can do. 
I've attached the project for anyone else that is interested but finds 
the usecases as daunting as I did.

RE: [OT] Utility to create DDL from a database

[Ashish Kulkarni]

Hi
there is a export tool, but the problem it creates DDL
sorted by table names, and it does not take into
account any database relationships, i may have to go
in manually and creates script..
for example there may be a table ABC which has a
foreign key constraint with table XYZ.
This database utility created DDL for ABC first and
then for XYZ.
So i run these DDL statements it gives error saying
that table XYZ is not created.
So i need some utility which will create DDL
considering these constraints

The shale usecases has several Clay examples.  The nightly is the most current. 
 You can find it here: http://svn.apache.org/builds/struts/nightly/struts-shale/

:--)  Well, the Clay documentation aspect can only get better.  I've been 
holding out for one of  the best.  I talked to David Geary this afternoon, (we 
talked about java while having some java) and he's going to help us out here.  

Shale has allot of value added features for JSF.  The new AJAX remoting, 
registration of managed beans with annotations, commons validator 
(soon/maybe/possibly Ajax enabled), Clay's reusable view page composition 
options and tiles integration to name a few.

They are similar but the differences is that Clay is based on a JSF component 
and can be used in JSP, HTML, XML or a mix. Clay also allows meta-data 
inheritance like tiles so that you can define a single component or composition 
of components that can be extended. Both support tapestry like views. Clay also 
has a notion of full XML views which is similar to the tiles page definition.  
It also has symbol replacement which is similar to tiles.

Shale is comprised of layers that you can choose to use or not include but all 
require the core library.  Besides some shared code, the core includes shared 
services that are common.  The Shale Application filter is the most visible but 
there are other utilities that are registered as managed beans by just 
inclusion of the shale core java archive.

The Shale Application filter is a controller that allows Shale to add 
additional life cycle events to the vanilla JSF life cycle without actually 
depending on a specific JSF implementation (RI, MyFaces).  The JSF lifecycle is 
one of the few parts of JSF that is not an extension point – loosely coupled so 
that it is swappable in the XML configuration file.

I'll direct you to the shale usecase example instead of duplicating in this 
response but this is the minimum stack to use Clay.
 
Added jars:
  * JSF archives (myfaces or RI)
  * Common-chains.jar
  * shale-core.jar
  * shale-clay.jar
 
Web.xml
* Common Chains – Loads a couple clay preprocess commands 
* Clay common full XML configuration resources.
* (Optional) Clay common full XML configuration resources.
* Shale Application Controller Filter Mapping
* Common Chains Configuration Startup Listener
* Faces Servlet Mappings

The warning you are seeing has to do with the core ViewController in Shale. The 
view controller is a managed bean that receives callback events for the 
additional life cycle events. There is an association of the view id with the 
view controller. The view controller is a managed bean that is registered with 
a naming convention (another pluggable part). In Struts 1.x terms this would be 
like associating a path with a action and form bean at the same time. The 
warning message is generated to inform that the controller filter couldn't find 
a managed bean matching the naming criteria.

Re: Problem with Struts Validator on machines without internet access

[Niall Pemberton]

The DTD's are shipped in the Commons Validator jar - when the xml config
file(s) are parsed (using Digester) local copies of the DTD (i.e. the ones
in the jar) are registered and should be picked up and therefore it
shouldn't need to go over the net to get them. This problem usually occurs
when the DTD declaration in your validatior xml config files is incorrect.

You should have something like the following at the top of your validator
xml files...

http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd";>

The above is for Version 1.1.3 of Commons Validator DTD - but the jar also
contains DTDs for 1.0, 1.0.1, and 1.1 - so declarations for them should also
work locally.

If your DTD declaration is correct, the other thing you might check is that
you have deployed the correct Commons Validator jar.

Re: [shale] Simple Clay example

[Richard Wallace]

Ok, let me try a simpler question.  Does anyone have an example of a 
simple one page webapp using clay and the HTML view?  It would be handy 
to have that available in the source repo so that users can try and 
consume different aspects of Shale a little at a time and come to grips 
with features one at a time rather than have to look at gigantic web.xml 
and faces-config.xml files.  It's rather confusing, especially given the 
current lack of  documentation.

The clay-config.xml file is empty except for the root element

Problem with Struts Validator on machines without internet access

[Bart Busschots]

Hi,

I'm trying to develop a Struts application on my laptop which spends 
quite a lot of it's time without net access. This should not cause any 
problems because the app it self has  no need to access the net at all 
but it is. The problem occours when I try to start Tomcat while not 
connected to the network. When I do that the Struts Validator throws an 
exception while Tomcat is starting. If I connect to the net the app 
start fine. The stack trace is as follows:

What version are you using?  The latest Javadoc for Struts Action 1.3
and Shale is here:
   http://struts.apache.org/javadoc.html

If you're using the nightly builds, the binary distributions should
include the HTML version of the website, including the Javadocs.

struts javadocs?

[David Thielen]

Hi;

 

Are there javadocs for struts anywhere? All I can find is in the source .zip
it has a bunch of xml files - but no html. I'm using my old struts javadocs
from 18 months ago.

b-di messages and dir="RTL"?

[David Thielen]

Hi;

 

Ok, I use a resource file for all text and then put it in the html page
using c:out, etc. But, what about Hebrew & Arabic? They need to be marked
with dir="RTL". I can make the message hi there but
then I can't escape any text and have to make sure I have escaped things in
my messages.

 

And I have a feeling this could get weird where some of the text on my page
I am pulling from a database and have no idea what it's direction is.

 

Is there a better way?

 

Thanks - dave

By "it" do you mean EL expressions?  If so, the answer is yes.  The
tags
don't have to know anything about this, because the JSP page compiler
generates the code to evaluate the expression before calling the setter
on
your tag handler.

This is unlike the case prior to JSP 2.0, where the page compiler knew
nothing about expressions, so you could only use them in tag attributes
of
tags that had special logic to do the evaluations themselves.

Also, can you use it to get the result of a method that's not really a

There is EL syntax for calling static methods, but not instance methods
like
List.size().

Lets lay out all the options:

1) ${test}
2) ${fn:escapeXml(test)}
3) 
4) 

And the scenarios:

a) "test" must be escaped
b) "test" cannot contain characters that need to be escaped
c) "test" must not be escaped

Then, keeping aside jspx/tagx files:

i) For (b) and (c), (1) wins, the criteria being:
  * Verbosity
  * Need for JSP tag invocation.
ii) For (a), (2) wins because I'm already doing (i).

Ofcourse, to each their own.

struts/jsp security/access question

[David Thielen]

Hi;

 

I have a page admin.jsp that if a user is not an admin, they should never
see. I can make the standard way to get there be admin.do but that just
invites a hacker to type in admin.jsp, so I still have to insure that
requests for admin.jsp are redirected for non admin users.

 

Each page (jsp) and it's Action class know who is allowed in. So I would
like to handle this in one of these two places. But the only two solutions I
have come up with are:

1.  A filter with all pages and who can access them in that one class -
dangerous because a new page can get added and the developer forgets to add
it to the authorization class.
2.  We have jsp pages that just do a check and redirect if the user is
not authorized. We then include the appropiate one at the top of each jsp
page. This works great if there are a small set of authorizations (this is
what I used before - every user was one of 3 types). However, it breaks down
for more than a couple of pre-defined authorization groups.
3.  All pages are accessed via preAction -> jsp -> submitAction. The
preAction sets a session attribute to the name of the jsp. The jsp page at
the top checks this attribute and if it is not it's name, it redirects to
the home page. As a session attribute, as soon as the user goes to another
preAction, they can't go back to the previous jsp. So it forces the
pre/jsp/submit ordering. The downside to this is the back button will be
limited to the jsp page that the global attribute is set to, not going back

Re: Struts JSTL & EL

What I mean is, can you use it inside third party (and your own) tags?
Also, can you use it to get the result of a method that's not really a
GETTER? Such as size() on a collection, even though there's no getSize()
method?

Re: Forward After response.getOutputStream

I think your answer suffices for this time, but my original objective

(1) Execute a download of an output stream for a file built on the fly
(2) Forward to another page indicating the download succeded.

That will happen automatically if you link to (for example) welcome.do
rather than index.jsp.  Most people force all requests to go through
an Action, either by adding a security constraint on jsp pages or
putting them under WEB-INF where the container is forbidden to serve
them directly.

Rather than try to control access to individual pages, though, I'd do
it at the Action level.  Is a user allowed to update, or only to view
the information?

The one place it is useful is to ensure well-formedness in jspx files.
jspx/tagx files are revolutionary in concept, and a step in the right

It's a matter of choice whether you include read-only data in your form 
bean. Either approach will work. Some prefer to reserve the form bean 
for marshaling input data, others like to keep all data in one 
'container' and use the form bean for both.

Thibaut wrote:

You should never have to do this manually. Struts will create the form 
for you provided your action mapping specifies the form name via the 
'name' attribute.



//get the parameter I want to put by default
String secteurDefault = request.getParameter("secteur");
if(secteurDefault!=null)
{
 if(form == null)
 {
   FormBeanConfig cfg = 
mapping.getModuleConfig().findFormBeanConfig("CorrespondanceForm");
   form = (CorrespondanceForm) 
DynaActionFormClass.createDynaActionFormClass(cfg).newInstance();

 }
//form = (DynaActionForm)form;
 form.set("partner_id",secteurDefault);
}

But the "form.set ..." doesn't work. Why ?


Because you've created a form object Struts knows nothing about. As I 
said above, you shouldn't need to do this. If for some reason you really 
want to, you need to put the resulting form into request or session 
scope so it's accessible from the JSP:


Second question : how do i put the form in a scope to be taken into 
account by the jsp ?


request.setAttribute("myform", form);

Set the value of the form bean property in your Action before you go

You are correct that there's no current way to control the order of view

Yeah, the mapper registration is working fine, it's just that it needs 
resources that are initialized by the view handler, so I need my view 
handler to be the outer-most one.


I guess I'll have to work around it by accessing that data via a static 
helper method on the view handler that'll lazy-init the required 
resources if necessary.

You can probably use the html:options tag but I like JSTL with 
html:select and html:option (I'm assuming you wanted Struts select tag?)









The above assumes your key in your Map is the value you want to use and 
the value in your Map is what you want to display for the option.

[shale] Simple Clay example

[Richard Wallace]

Hello,

I'm trying to get a simple clay example up and running so that I can use 
the full html view (which is similar to facelets, correct?).


I looked at the use cases and copied the web.xml, faces-config.xml and 
clay-config.xml and stripped out anything that I didn't need, like 
Spring and dialog stuff (I'll play with that later).  So, what I'm left 
with is a pretty standard looking web.xml with the 
ShaleApplicationFilter added, a context param for 
org.apache.shale.clay.COMMON_CONFIG_FILES, and a servlet filter for the 
FacesServletFilter to be mapped to *.html files.


The clay-config.xml file is empty except for the root element 
.  The faces-config.xml is empty as well.


I've got a simple default.html page with just a single  element with 
a jsfid="commandLink".


When I deploy the webapp the logs are as follows:

Set the value of the form bean property in your Action before you go to

in the formBean itself if you know it's always going to be the same 
default value.


ie in Action:

MyForm myForm = (MyForm)form;
myForm.setPartner_id( defaultId );

in ActionForm:

int partner_id = 20; //or whatever you want it to be

This is definitely a valid concern.  But using JSP 2.0 lets you use EL
expressions for the attributes of *any* JSP custom tag, not just the tags
that know about them.  And this is still quite valuable.

This is not possible, either with or without Struts.  The servlet
specification requires that the sessions for each web application be
independent of each other.

When you think about this a little, it is easy to understand the reasons for
this restriction.  The most important one is that the classes visible to
each application are different, because each app loads its own
WEB-INF/classes and WEB-INF/lib directories.  Therefore, even if the session
object were shared, a session attribute stored by webapp A might not be
usable by webapp B, simply because webapp B cannot see the class for that
object since it exists only in webapp A.

You will need to use a strategy other than sharing sessions to share
information between these two apps.

RE: [OT] Re: Database Access

[Frank W. Zammetti]

I third the suggestion  :)  But, I would look at the Spring JDBC package. 
If your going to do naked JDBC, they can make your life a lot easier.  I
would be using it now myself, except...

I have over the course of a few projects developed four classes that I've
used often when I couldn't really justify Hibernate or even iBatis.  One
is a database connection manager class that all JDBC classes go through. 
It deals with getting a connection (either created on-the-fly or from
JNDI), errors, transactions, etc.  I've also developed two other classes
that allow the ability to externalize all my queries... I do a simple
getQuery(queryID) call and I get back the query, which I can then do
parameter replacements on (just like a prepared statement, but it's not),
and send it off to the manager to execute. The fourth class is a
disconnected ResultSet object that is very handy (and tends to make the
application more efficient overall).

The reason I'm mentioning these things is that they are not that big a
deal for most people to develop, and if you wrote them they would evolve
over time and really make your life easier (probably 90% of them were
written over the course of two days during one project, then they got
tweaked sligthly during a few other projects).  I usually wouldn't
recommend doing something like this yourself, but it is a great learning
experience, and you wind up getting exactly what you need in the end, so
it may well be worth it.

In any case, don't dismiss JDBC out-of-hand, as many people seem to do
these days.  You *do* want to look at the alternatives of course, but done
correctly, JDBC can be a very good friend.

You can probably use the html:options tag but I like JSTL with 
html:select and html:option (I'm assuming you wanted Struts select tag?)










The above assumes your key in your Map is the value you want to use and 
the value in your Map is what you want to display for the option.

Struts creates its own session object?

[Martin Morawetz]

Hi,

We have two web applications, a Struts-application
and a strutsless application.

Both web applications have to use the same session.

It appears that both apps do have a session with
the same id, but the session-objects are different
and so all the attributes the two session-objects
contain.
These session-objects exist at the same time.

Does Struts provide it's own session object? And
if so how can I share the session between the
two apps? I depend on the objects stored in the
session of the strutsless app.

As it may be important to the problem:
These two web applications run on two different
subdomains of our domain. To be able to use the same
session for both applications we specified a cookie
domain (Feature of the Resin Servlet-Engine).
This feature works fine except for the strutspowered
app.

You can use Struts-Menu, it's sure is a good thing.
The only issue is, that you can't generate the first menu level

So if you wan't to have something like:

Group 1

Group 2

You have in mind, that you have to put the Groups in JSP, but
you can build the rest of the structure dynamically using DB or
some other information source.

Or if you don't need any automation, you just use XML, like described in 
the S-Menu docs. That's real easy.

BTW Guys if someone of you knows how to build the first menu level

AW: Urgent help needed

[Eickvonder Bjoern]

Hi,

as you are posting this on struts list I suppose you want to do something on 
the server If the user closes its browser, something like storing his logout 
time?
Though you might be able to do some cleaning operation on the client (via 
onunload and such methods) for some browsers, it might be even more difficult 
to send a message to the server during this cleanup. 
So what can you do? You could catch the invalidation of the session after its 
timeout (see HttpSession*Listener interfaces). But obviously if you for example 
have a login-mechanism that prevents a user to login twice and a user closes 
its browser he can't login til his session has reached timeout.

Re: Modal window

[Aldo Vadillo Batista]

There's another problem related to the modal window: it not permits
submitting there.
You have to create an artifact to make this (put a frame inside the
modal window and put the original page to display inside the frame).

Re: file upload via struts

[Vikrama Sanjeeva]

Hi,

 Good and complete example is here:

http://www.roseindia.net/struts/strutsfileupload.shtml

and check this too:
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=next_topic&f=58&t=006647&go=older

At the end of the day, you need to code Java I/O for file (s) manipulation.
If you read the 1st link, then can use this piece of code for saving file.

***
   public void saveFile(InputStream in, File dst)throws IOException {

   // dst: is a destination variable; where u r going to write file
which is lready created on server.
// in: is an inputStream of the source file that is, file from
where u will copy the contents to dst. InputStream will be open on clients
file on his machine.

OutputStream out = new FileOutputStream(dst);

// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
System.out.println("writing to file and len = "+ len);
out.write(buf, 0, len);
}
in.close();
out.close();
}

***

Hope it helps.

Bye,
Viki.

menu system in front of a J2EE application

[Rivka Shisman]

Hi friends,

 

I need your advice about this:

 

I have a J2EE application that runs on Websphere application server.

The application contains a several web projects (WARs).

I need to implement a menu page that will be the front for all that web
projects.

 

1. Should that menu be a separate web project (WAR) in my application
and contain references to the other web projects? Or is there another
way?

2. Is struts-menu suitable for this purpose? Is it mature enough?

 

Thanks

Rivka

 

RE: Urgent help needed

[Rakesh.Bhat]

Hi 
Window.onclose works with only IE. However, you can try unload  event.

Refer the code snippet below
function onClose()
{

alert("Warning. You are closing the app!")
//do cleanup operations

}

window.onunload=onClose
