Import MessageResources to JavaScript

[Anthony Martin]

In order to make my JavaScript use text found in MessageResources, I have
this line in the source of all of my .jsp files:

---

---

The contents of jsMessages.jsp is as follows:

--- 
<%@ page language="java" contentType="text/javascript" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

var appMsgs = new Object() ;

appMsgs["general.title"] = "" ;
.
.
.
.
appMsgs["general.confirm.close"] = "" ;
---

This works great when I specify each message explicitly.  But is there a way
to iterate through all of the messages so that I can expose all of the
messages all of the time?

Command, n.:
Statement presented by a human and accepted by a computer in such a

Re: Design consideration: Client side validation

[Matt Raible]

Why not use the Validation framework (in nightly builds) to do it?  It can do
both client-side validation and server-side, it already contains the javascript
methods and everything.  Pretty slick stuff.

RE: Struts and Silverstream

[Brian Holzer]

This is a resolution for anyone using struts with Silverstream and not having session 
persistence.

>>> "Krueger, Jeff" <[EMAIL PROTECTED]> 10/26/01 08:49am >>>
Brian,

Thanks for letting me know that the web.xml matter and the
deployment plans seems to not.  I have been meaning to look into that, but
haven't had much time to play around with it.  I'm glad that solved your
problem.  One side note, you mentioned that you are using the workbench to
do your development.  I would except that when it build the default web.xml
it should put some default for the session value.  I'm not bashing the
workbench, it is actually a great tool to start with.  Myself I enjoy using
JBuilder and ant to do my development.  If you ever want to switch over to
that as your development environment let me know and I can get you set up
with the ant files that are needed.

Your design looks ok with the one form bean, I was just reading it
wrong.  Sorry.  Also the reason why I was asking about the iterate is
because in the struts documentation the example that looks like yours is for
a hashmap, not a collection.  Since you are returning a collection I wasn't
sure if you were having problems there.  Often when I use a iterate I have
to specify a lot more parameters.  I will have to try it out with out them
and see how it goes.  

Glad your up and going, let me know if you have any other problems
or design questions.

Jeff Krueger

Jeff,
   Only one form?  This app is going to expand to insert/update/delete on
several tables related to our user and data/page level security.  I am just
trying to get one good thread going for the user table and then use this
thread as a template for the rest of the app.  The UserForm relates to the
fields in the user table and since the search criteria in userQuery.jsp are
fields from that table, I thought that I would use the same form for
entering the search criteria and for entering a new user or editing an
existing one.  Is this wrong or bad design in your opinion?

>userQuery.jsp -->> userquery.do on success -->> userQueryResult.jsp.  
>How do you get to the userAction.do.  Is that from a different link.

>Also in the userQueryResult.jsp page you are iterating through the

Yes, the iterating through the collection works to produce
userQueryResult.jsp and I create a link in the interation 

which then gets me to the userAction class.  When I get to the userAction
class, my plan is to get the key from the link (APP_USER_ID)  and then get
the collection of userForms from the session and iterate through that until
I find the one that matches the key and the setAttribute that to the session
and then the user.jsp will come up with the data for the user.

HEY JEFF,  as I was putting together this reply, I got your other message.
I gave it a try first by increasing the time in the SMEARDeplPlan.xml but
that didn't work, but then I added the 

300

into the web.xml and voila it worked.  Thanks a million, I spent way too
much time on this one.  Any comments on the rest of my repy would be
appreciated.  I owe you one, thanks again.

Brian

Brian,

Well...  It all looks good to me.  You are doing some things a
little different than I do, but it shouldn't matter.  Question for you.  I
realize this is kind of a first pass at a struts app, but I am curious why
only one form bean.  I haven't deployed the app and looked at it.  Also I
was trying to follow the page flow.  I see that you can start at 

userQuery.jsp -->> userquery.do on success -->> userQueryResult.jsp.  How do
you get to the userAction.do.  Is that from a different link.

Also in the userQueryResult.jsp page you are iterating through the
collection.  Does that work?

Brian,

If you can send me your config.xml, and the two action classes that
you use to try and put the object into session and the one that you are
trying to get the object back out of session I will take a look at it.  None
of the apps that I have built have run on solaris, but I would be surprised
if that was the problem.  All the apps that I have built do exactly what you

[ANNOUNCE] Struts Console v1.1 beta 1

[James Holmes]

Struts Console version 1.1 beta 1 is now available.

http://www.ejcenter.com/struts/
http://www.ejcenter.com/struts/struts-console-1.1b1.zip

This release has some very cool new features.  I have
added support for NetBeans and Sun Forte for Java so
that you can "plug" the Struts Console into these IDEs
for seemless development of Struts applications from
one development tool.  I have also added a "Tools"
menu with one tool, the "JSP Converter".  The JSP
converter converts ordinary JSPs into JSPs that use
the Struts HTML tag library.  This should speed up the
development of new Struts applications.  There's more
too...


Changes with Struts Console v1.0b2

  *) Struts Console is now able to be plugged into
 both Sun's Forte and the NetBeans IDEs as a
 module.  This allows users to seemlessy manage
 Struts config files with Struts Console from
 within their IDE.

  *) Added JSP converter tool for converting JSPs to
 use Struts' HTML tag library.

  *) Added ability to add new form beans from the
 "Form Bean" tab on the Action screen.

  *) Added "Referencing Actions" tab to "Form Bean"
 screen so that you can see which actions use the
 given form bean.

  *) Updated windows batch file to no longer require
 editing to get the app running on windows.
 Thanks to Clóvis Yutaka Harada
 <[EMAIL PROTECTED]> for sending me this
update.

  *) Fixed bug where the "default Action" warning
 message was being displayed when it wasn't
 supposed to be.

  *) Fixed bug where "add" dialogs were not showing up
 properly on Linux under certain window managers.
 Thanks to Ken Beyer <[EMAIL PROTECTED]> for
 pointing this out and helping me debug the
 problem.


As usual, let me know if there are any features you'd
like added or if you come across any bugs.

Thanks,

-james

Re: Digestioin pill needed

[martin . cooper]

You shouldn't push your 'a' and 'm' objects on to the stack, but let the 
Digester create them as it encounters them. You probably want something 
like this:

digester.push(this);
digester.addObjectCreate("root/action",
 "yourPackage.yourActionClass");
digester.addSetProperties("root/action");
digester.addSetNext("root/action",
 "yourAddActionMethod");
digester.addObjectCreate("root/method",
 "yourPackage.yourMethodClass");
digester.addSetProperties("root/method");
digester.addSetNext("root/method",
 "yourAddMethodMethod");

In the class in which you implement this, you would add two methods, which 
I have named 'yourAddActionMethod' and 'yourAddMethodMethod' above, 
something like this:

public void yourAddActionMethod(yourPackage.yourActionClass obj) {
 // Do what you want with the new action object
}

public void yourAddMethodMethod(yourPackage.yourMethodClass obj) {
 // Do what you want with the new method object
}

Hope this helps.

Migrating from tomcat 4.0 to tomcat 4.01

[Domingo Aguilera]

I have a webapp that runs properly under tomcat 4.0.
Struts jar and commons jars are as from 9/19/2001


Now I want to make such webapp run in tomcat 4.0.1 but it seems the digester
can't instantiate some classes from the struts-menu example.

What I have noticed is that from tomcat 4.0 to 4.1 there was a change about
going from crimson to xerces.

When tha app was run in tomcat 4.0,  I added crimson.jar and jaxp.jar to
myapp/WEB-INF/lib, but in tomcat 4.0.1 I had to remove such files and let
xerces work.

In tomcat 4.0.1 when init() function from my CustomActionServlet is run
Digester works fine till have to lead with the instantiation of
MenuRepository class.

I've noticed that the digester don't send the verbose output when dealing
with MenuRepository.

I will thank any idea that would make solve this prob.

Tks. Domingo

RE: Flash button and forms with struts

[Joe Niski]

Title: RE: Flash button and forms with struts





on a simpler level, you can send name/value pairs to a Flash movie from the  or  tag in the JSP that references the Flash file, e.g.

 


the value can be dynamic, e.g. an expression or tag that returns a string. When the Flash movie loads, a variable named "param1" is automatically declared and initialized to "param1Value"  - your Flash scripts can reference the variable without declaring it.

Re: How can a retrive an Action instance with a path ?

[Ted Husted]

The ActionMappings are already in application scope, which is how the
html tags use them.

I suppose you could do the same with your Action, put a reference to it
in application scope, under a known name. Usually, you would obtain
whatever you needed from the Action first and put it into the request
scope, and have the tags look there. The View is not usually aware that
the Actions exist.

Iterating thru collection of nested beans inside form

[Kraffmiller, Ellen]

I am having trouble using the "indexed"  attribute in the html form tags.

I have a form that contains section that is repeated a variable number of
times.  I am representing the controls within that section as a bean.  My
form bean contains a collection of "section beans".

class SectionBean {
   private String name; 
   public String getName(){return name;}
   public void setName(String val) {name=val;}
  
}

// ItemForm is mapped to the Action class handling the form
class ItemForm extends ActionForm  {
private Collection sectionList;
public Collection getSectionList() {return sectionList;}
public void setSectionList(Collection coll) {sectionList=coll;}
}

My First try was to do this:





 

This compiles and runs, but the property value does not get populated into
the nested bean inside the form bean.  I think that's because the translated
html name, "section[0].name", does not correspond to a property of itemForm.

 If  I try:
 
   

I get an error because "itemForm.sectionList" is not defined as a bean in
any context.  

I also tried defining the collection before the iterate section:

  


 

 
This gave a run-time error when struts was populating the bean.

Any help would be greatly appreciated.
Thanks
Ellen

Re: How do i generate a unique checkbox name when iterating a dynamically created page

[dhay]

Hi Reid,

I posted a note a while back on this.  The indexed attribute available in the

myCollection[0].myCheckboxValue.  If you can't use that, you'll have to use
scriptlets to generate the same thing.

Subject:  How do i generate a unique checkbox name when iterating a dynamically

Read through the archives and could not get any of the variations that I
found re iteration/index to do what I need. Would appreciate any
guidance.  I am using






























   

where lineList is a Vector used to generate a page of data.  lineList
can vary in length.  I need to be able to update the checkbox values in
my form.  I assume that to do that I need a unique name for each
checkbox ( ie "checkboxname+index" is what I would like to use) so that
I can specify which checkbox i am referencing when calling a setter
function to update the page & backend data file(s) when user submits;
how can I generate a unique name for each checkbox?  Or is there an
easier means of doing this?

Subject:  PROPOSAL: collectionProperty attribute in 



PROPOSAL: collectionProperty attribute in 

Abstract:
 A new attribute "collectionProperty" which will act like the
current "colllection" attribute except that it specifies the property of the
form which contains the collection thereby elimating the need for a
 and decreasing coupling between the JSP page and the name of the
form bean defined in struts-config.xml.

Proposal:

A common approach to using the  tag uses the collection,
property, and labelProperty attributes to specify which bean properties to use
to generate the  tag. This works fine when the collection is sent
separate from the form.

There is a problem when the collection is actually a property of the form. The
collection attribute EXPECTS an actual collection, and will NOT accept a
property.

Scenario:

 You have a form named "formBean" with a collection of beans under a
property "users." You want to use the bean properties "userid" and "username"
to render values and labels for the html options.

 In order to do this, you would need something along the following lines
of code:
 
 
  
  
 
 

Problem with this scenario:

 If you notice, we must use the bean:define tag. First of all, this tag
adds overhead: It is using reflection to copy a collection into a page scope
variable. Also, the form now must KNOW what the name of the formBean is.
Wouldn't it be nice if you could just tell the  tag which
property contains the collection within the form bean? The  tag
would call this property on the formBean associated with the Form.

Updated scenario;

 This is what the jsp code will look like with the proposed change:

 
 
  
 
 

Proposed Change:

 We would add an attribute to  called "collectionProperty"
this property will specify what property under the current form bean contains
the collection. The property and labelProperty attributes will function in the
same way as they do when they are used in conjuction with the "collection"
attribute.

Rationale:

 I believe this change will give the  tag more
functionality and make it easier to use. As well as the help in certain strut
design patterns.
 Consider the following. You have a Class called "CommonForm" which
inherits from ActionForm. This form contains several common elements like
State/abbreviate pairs, etc. All of your other forms inherit from CommonForm so
they also have access to this data. The above proposal would make this design a
lot more convenient.

 I would like to hear comments as well as votes for this change. Thanks

Subject:  Iterate will be the death of me.




  Alright, I've completely simplified my code to the bare-bones, have tried
following the iterate examples provided by the kind souls who have posted
example code, but I can not for the life of me get  and
 working together.

  I do have the <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
tag in my JSP.

  I am using the October 17th nightly build of struts.jar.

  The ActionForm bean, defined in my struts-config.xml as
tournamentPlayersForm, in session scope:
private Vector mUserList = new Vector();

public Vector getUserList()
{
return( mUserList);
}

public void setUserList( Vector userList )
{
mUserList = userList;
}

public FormUser getUser( int index )
{
return ( FormUser ) mUserList.elementAt( index );
}

  ...mUserList contains a vector of easy-to-swallow FormUser objects:
private String mUserName = null;

public String getUserName()
{
return mUserName;
}

public void setUserName( String value )
{
mUserName = value;
}

  The JSP in question:

  


  When the JSP initially loads, it properly displays the number of textboxes
based on the size of mUserList and even fills them in with userNames if the
userName values were previously populated.  However, when I retrieve the
same vector after this JSP is submitted, the userNames never get populated
with the values entered into the  boxes.  When I view source,
they appear as so:




  Andrew van der Voort (bless this man for posting code snippets) posted his
way to get it working which I've tried but unfortunately had the same
results - having the same setUserName method normally used in my FormUser
object and put it into the form itself taking a String[] as an argument,
then on the validate() event of my ActionForm go through the member variable
I assigned the String[] to and pull the names out that way.  This String[]
never gets populated either.

  I've tried every possible combination of tags, I've followed everyone
else's example of how to get iterate working, and I'm still looking at null
userNames.

  Help?

Visual Age 4.0, Tomcat 3.2.3 and Struts

[Greg Berger]

Does anyone have Struts working with Visual Age 4.0 Pro and the Tomcat Test 
Environment 3.2.3 from IBM? When I put the struts-example.war file in the 
webapps directory, Tomcat deploys and starts it with no problems, and the 
index page displays. If I attempt to follow the "Register..." link, I get

java.lang.NoClassDefFoundError: org.apache.struts.taglib.html.HiddenTag

If I follow the "Log On..." link I get
java.lang.NoClassDefFoundError: org.apache.struts.taglib.html.TextTag

It appears to me that Tomcat cannot find the html taglib packages. I have 
imported Struts into a Visual Age project, but if I include that project on 
the TomcatRunner classpath, I get

java.lang.reflect.InvocationTargetException: java.lang.InternalError: (Ex02) 
An error has occurred.

I have the same problem with the struts-blank.war - the index page displays 
no problem, but if I add any jsp pages that use the html taglibs I get the 
class not found errors.

On occasion, after goofing around with this, the struts example app will 
start working, but none of the jsp's get compiled into the "JSP Page Compile 
Generated Code" project in VAJ. I've tried a bunch of different experiments, 
and it seems very close to working, but I just cannot get it functioning 
fully. Any insight will be greatly appreciated.

Agreed.  A short answer saying "See the FAQ at this URL: http://.."; not only 
directs people to the answer for a particular question, but also teaches them to 
look there for their next question.  Another thing I've done on the VisualAge 
for Java forums is to post a weekly message about the existence of the FAQ. 
That way someone browsing recent messages is bound to stumble upon the link, and 
anyone nice enough to do a search in the archives for "FAQ" will find it.

Ted Husted manages the jGuru Struts FAQ - would he be willing to post a message 
along these lines to this list every week (I can send the one I use for VAJ if 
you'd like to adapt it).

Re: html:link page or forward?

[Ted Husted]

The page form taked a hardcoded URI. If you change your page names
later, you will have to update these.

The forward form takes a logical name, and reads the actual URI from the
struts-config. This is a much better approach. If you change your page
names, you can just update the struts-config.

Re: Struts, JSP, Servlets and dB

[Ted Husted]

Extending the ActionForm to handle the SQL statements might be a bit
much. 

People often handle data access directly from the Action. The Action
pulls the data out of the ActionForm, puts it into a SQL query, and then
puts the result back into the ActionForm, or an ArrayList. Just as
people have often done with conventional servlets. 

Though, this doesn't provide the best separation of controller and
model.

Right now, I'm working on a slightly different approach that keeps the
data access seperate from the rest the Action. I specify a data access
class in the ActionMapping (using the parameter property). The data
access class is a "model bean" with a standard method for calling a SQL
query. The model bean looks a lot like the ActionForm bean, except that
it uses native types. The model bean is subclassed for each query. All
the Action does is populate the model bean, and call its query method
("execute"). (As a convenience, my model beans can populate themselves
using reflection, so this becomes one call - execute(form).) The data
access class then returns a list of beans generated by the query. 

The sample application is Artimus, which uses the Scaffold package.

Different Actions calls in one Tag

[Roland Berger]

Hi all

I'd like to put severel (submit) buttons into one  tag. Each of
this button should execute a different action. The problem is that only the
action given in the  tag is called.
Is there a way to tell struts to analyze the request for a property "action"
and if the "action" property is defined in the parameter list it calls the
action given there? (Of course all input text fields definded in the form
shall be transmitted.)

See example below how I imagine this (finally the action "actionName.do"
shall be called instead of "/dummy.do"

Thanks for any help

Re: Knowing where you came from

[Ted Husted]

The underlying problem is that the framework does not generate the
request, the client does. The client is suppose to add certain
properties to a request, which I think include the referring page, but
you have no control over this, and personally, I would not depend on it. 

If there is information that should be part of a request, then it should
be part of the API contract, and included in the form or the link. If
the request is incomplete, then the client should be routed to an error
page.

Besides hidden properties, the parameter property in the ActionMapping
can often be used to map different tasks onto the same Action. 

If retaining a history of pages for your clients is important, that is
something you could create in the session and maintain with a subclass
of the ActionConroller. Each outgoing ActionForward could be added to a
self-limiting stack. However, Web application servers do not persist the
session, so if it times out, the history would be lost, unless you also
keep it in a cookie.

Re: Fwd: Dynamic message

[Ted Husted]

The nightly build includes a message object with a seperate queue than
errors. 

Personally, I just use the errors queue for these kinds of messages too.
After the Action determines there is not an error message, I have it
check for confirmation messages, using the same ActionError queue. Works
just fine.

Re: Application Ressources from database?

[Ted Husted]

For real-time retrievals, in a model 2 / MVC environment, you would make
such retrievals in the Action, and then pass the pertinent messages
along in a bean. For i18n, you would make the user's locale (stored in
the session) part of the database query. 

If you want to maintain the ApplicationResources from a database,
options would include having it created from the database as part of the
build process, or overriding the constructor so it retrieves information
from the database rather than a file.

I think I took all the steps outlined in web-inf/readme.txt. I changed the poolman.xml file to reflect my local oracle drive and db. (the poolman.xml file works fine with the sample poolman-webapp from codestudio).

When I try to search or log onto the admin interface I get an error in the browser:

The Catalina console displays:

Do I have to create the table "article" in the Oracle db or will the app do that automatically?

I'll second that.  Many many questions have been posted on this list that are clearly 
explained in the documentation.

The documentation isn't perfect, and can be confusing at times, but some due diligence 
should be expected.  Not only is there documentation, but the source code is available 
and it will tell you the truth like no other!

About a month ago I was thrilled to see someone respond to a question with "RTFM"!

Re: Design consideration: Client side validation

[Sandeep Takhar]

The struts validator performs client side validation,
but then repeats again in case the user has turned off
javascript.  This is the preferred approach.

The nice thing is, most validators are pre-configured
for you and you don't have to write java or javascript
code in order to use these pre-defined validators.

It is pretty cool in my opinion.

onmouseover attribute of html:link

[lisa ward]

Hi,

Can anyone see what I am doing wrong here.




   
 


 


I have a bean, which has been exposed using the image1 variable.  Everything 
else (image2 and container) works fine.  The problem I am getting is that 
when I view the source of my page the value of image1.getName() and 
image1.getLocationURL within my onmouseover handler are not bein resolved to 
the values.  This is the output of view source.



I am very sorry about the mess, I hope you can read the code.

Any responses will be greatly appreciated.

Thank you for your speedy response

Re: html:options with FormBean

[Peter Pilgrim]

There are two ways but the best way is to set up a simple bean
like "LabelValueBean" that has two attribute; the option value and the
option description

public class LabelValueBean {
 String label, descrip ; 
 public String getLabel() { ... }
 public void setLabel( String newValue ) { ... }
 public String getDescription() { ... }
 public void setDescription( String newValue ) { ... }
}

Write a collection and store  LabelValueBean inside it.
Write an action form that allows you get the collection or add
the collection directly to the request scope under a known name.
Then you write your  tags to get all the options
You need to tell  the JavaBean property to get the value ie "label" == 
getLabel()
and the display text "description" == getDescription

Comment on using the Struts platform for this project.

[Alex Colic]

Hi,


I have to create a app that allows users to change/input data into a
database. Sounds simple. Problem is I have to make it dynamic so that is
will work with any database or table. I have a back end VB app that will
send me:

Field name
Field caption
Field type
Field display type e.g.. radio, drop down, text box etc.

I then need to dynamically create a form with form elements.

Is Struts suited for this or should I stick with a plain servlet?

Hello there,

i am currently trying to find a way to call another action
(ActionB) from within an action (ActionA).
as and ActionForeward object should be returned from an action i
cerated a new ActionForward
with the path of the URL, or the action i wanted to call, but it
doesn´t seem to work.

The problem is that i want to call ActionB with parameters:

"actionB.do?command=XY"

The parameters are calculated in ActionA .

This is what I tried:
...
ActionA extends Action
{
ActionForward perform(...)
{
  return new ActionForward("actionB.do?command=XY");
}
}


I can foreward directly with a requestdispatcher but browser
doesn´t stop properly and continues loading.
I think there should be a way using the STRUTS calsses ..

Can anybody help please? I think I made some mistake ..

Thank you
Wolfgang

RE: What is proper way to determine ActionForm type?

[Justin Piper]

Yes, you're right, you would lose that, and I don't think there's a clean
workaround in my solution, save for adding a visit() method for every
ActionServlet you want to support (ick).  AFAICT, the way Ted suggested will
still work with multiple different actions, so that would be the way to go
if you want to use multiple forms with the same servlet AND multiple
servlets with the same form.  In any case, this whole plan seems to be
contrary to the design goals of Struts, so I'd suggest thinking carefully
whether handling several forms with the same action is really the way to go.

Subject: RE: What is proper way to determine ActionForm type?


Aren't you then losing the ability to have one form used by many
actions?  For instance, you can have a "UserForm" which is responsible for
holding user data.  This form might be used on the login page, the signup
page, the change details, reset/resend password pages... and so on.  Then
you just have one action for each of the different pages.  

As I understand it, what you are suggesting is having something like this
(pseudo-code) in the Action class:

  if (form is login)
doLogin(form);
  else if (form is signup)
doSignup(form);
  ... and so on...

So effectively what you're doing is trying to write one action class that
handles all your scenarios?  

IMHO I think the separation of data nad logic that the form/action class
separation provides is a good thing, for reasons stated above.

Re: Knowing where you came from

[Peter Pilgrim]

Expresso frameworks has the concept of states within a Controller (a direct subclass
jakarta struts action). Where can write states, which are methods prefix with "run" and
and suffixed with "State"  such as

MyController extends Controller {

 public void runPromptLoginState(  ) {  }

 public void runProcessLoginState(  ) {  }

 public void runPromptSubscriptionState(  ) {  }

 public void runProcessSubscriptionState(  ) {  }
}

Subject:  Re: Knowing where you came from


The problem is that, in a Web app, the client can request any valid URI
at any time, and the application has to deal with that.

Another way of looking at this is

+ what is our current state,
+ what changes are being requested to that state, and
+ can we make the change from the current state to the requested state.
+ if not, what other changes are required to move to the requested
state.

This is the general direction of the workflow project, where the state
is represented as a series of nested steps.

So if a request could not be completed because we were missing a name,
we could retain the current input, but roll back to the closest step
that captured a name, and proceed from there wizard-fashion.

For more about the workflow project see

http://jakarta.apache.org/struts/proposal-workflow.html

There also some preliminary Struts demo code in Struts-Simple

Re: Struts and IPlanet 6.0 (Test Drive) - Solution

[Matt Raible]

You are correct, and I was able to get the struts-example (that I ported) to
work on iPlanet Application Server (SP3) without adding anything to my
classpath.  However, I used the iPlanet Deployment Tool to register the
application.  There are other command line tools to register the application,
and even ant extensions, but both of these seem to require that the jar's be
added manually to the classpath.  Just some iPlanet qwirks, nothing more.

Re: default scope for struts actions

I'm not sure, I think default scope is session.

see this in ActionMapping.java

protected String scope = "session";

Peter--

I would take a look into the NetBeans project
(NetBeans.org) or Sun's Forte Community Edition (based
off of NetBeans).  These are both great IDEs and are
free to use.

I will also be releasing a new version of the Struts
Console that "plugs" into NetBeans and Sun Forte very
soon.  This will allow you to manage Struts
applications seemlessy from one central development
tool.

How can Struts support tag

[pipashu]

I use Struts to build a web. I have some directories to store jsp pages,
most of thes pages have images, for example, ,
When I execute a action (*.do), then forwards to a jsp in one of these 
directory(not root directory), this page can not show images. I wonder Struts 
does not support a) .
I know Struts support b) 
a) can be used in dreamveaver,
but b) can not be used in dreamveaver,
This is my problem.
Please ask how can I resolve this problem.
Thanks in advance.

Re: Real time web page?

Also, the remote scripting API that I created has the capability of
short-circuiting responses in a similar manner.  Its application-dependent
how that logic works, either by message ID or by a date stamp or other
mechanism, as its just another parameter being passed from the client to the
server.

Re: Does struts spawn a new action class for every user?

The documentation is very clear that there is only one instance of the
action class. You should not use member variables in action classes.

Hey Folks,

  If I declare variables outside of the perform() method in my action
classes, does this mean that multiple simultaneous users will overwrite
each others variables? i.e. does struts spawn a new action object for
every user session, or does it keep the same object and just call the
perform() method each time a user calls the action?

  Any feedback would be very helpful,

RE: java IDEs

Hi,
well, if it is just for bean-creation...
Why not use a uml-tool with code-generation?
(eg. ArgoUML v0.9 (the experimental one) has code-generation-features)

As a side-dish you can get uml-documentation for your bean-classes...
and still you use your preferred IDE (...UltraEdit...).

Struts, JSP, Servlets and dB

[Daniel WAMARA]

Hi,

no good answer has been given to me thru all the websites I went to but I 
should now have to ask my question here I think : I'm brand new in Struts' 
world because I've been hired by a company using it.

Having worked before with servlets where querying databases where a matter 
of SQL statements, I'm not a bit lost : all the examples I've seen were 
using kinda "XML databases" but I now have to make a short application to 
see that I'm a bit good in Struts before beginning my real project next 
week.

I would like to know if I can use some "normal" SQL statements in my Form 
objects extending the ActionForm class ?

Writing the config-struts.xml file, writing the form objects, writing the 
lines of the Actions are not a problem because I now have a good look over 
it but how could I use "normal" databases or tables like I was doing before 
with servlets, like defining the driver, getting the connection, making 
statements and so on...

I was a bit long but it was for a good explanation.

Thanks for helping,

Daniel WAMARA

Re: Design consideration: Client side validation

[John Yu]

If client-side validation is preferred, one paradigm is:

   - use js to do client-side validation,
   - don't do validation in Struts, and
   - let your business logic do the final safe-guard to
 throw exception if the values are invalid.

The main consideration is the maintenance of the js code.

HowTo: Struts Template containing JSP with Action and ActionForms associated

[storck]

Hi,

I have a template build with struts and I have a JSP wich uses that template
and looks like the following:

<%@ taglib uri='/WEB-INF/struts-template.tld' prefix='template' %>







AND I have a struts-config:



















If I use "" I get a exception wich says that
the bean "showBoxesBean" could not be found in session so I thought I must
use "" in my
JSP. But than I get a "javax.servlet.jsp.JspException: Servlet Exception"
throwen in the template-insert-tag.

The Action associated with my ShowSelectionBoxes.jsp has the duty to fill
some selectboxes.
What I want to do is to have a JSP build with template wich has on the left
side a sidebar containing 3 selectboxes and in the middle showing some
content wich is although a jsp with a Action and a ActionForm

PLEASE can anyone help me how to achieve that ??

Re: java IDEs

[John Yu]

Peter,

Borland's JBuilder is a popular and powerful commercial IDE. Its 
BeansExpress wizard can generate beans for you from the properties 
specified by you. They have a free bare-bone Personal version available for 
download:

http://www.borland.com/jbuilder/offers/

NetBeans is an open source IDE:

http://www.netbeans.org

If you need a tool to go through your JSPs and generate formBeans 
automatically from the , you may want to take a look at 
Scioworks Camino,

http://www.scioworks.com/scioworks_camino.html

Hope this help.

Re: Knowing where you came from

[Arnaud Chiaberge]

Hi all,

I have exactly the same concern. I'm using one Actionform for several
purposes (coming from different JSP pages), and I'd like ot be able to know
where I come from...is it possible ?

Also, same problem when using an Action (a dispatcher one) that can be
called from any JSP page...once again, I need to know from which JSP page
this Action has been called (in this specific case, I don't have any
"input=" entry ine the struts-config.xml file)

Thanks in advance for any help.

Re: This list NEEDS a FAQ

[John Yu]

There's an FAQ on husted.com which contains frequent questions asked on the 
list,

 http://www.husted.com/struts/FAQ/index.htm

Maybe we need an eye-catching link on jakarta's website pointing to the FAQ 
page? What do you think, Ted?

Re: This list NEEDS a FAQ

[martin . cooper]

There already is a FAQ, here:

http://jakarta.apache.org/struts/userGuide/kickstart.html

I agree with the sentiment behind your suggestion, though. The real problem
is that many people don't refer to the FAQ, and don't check the mailing list
archives, before posting their own questions to the list. Unfortunately,
these are typically the same people who believe that their own time is more
valuable than that of other people on the list.

I don't know what the best solution is for this problem. Moderating the list
is one option, but with the typical daily volume of this list, I don't see
anyone readily volunteering for that task. ;-) Perhaps the best we can do is
to collectively enforce the "do your own research first" reaction.

So whenever you read a message that asks a question that is already on the
FAQ list, don't reply with the answer, but reply with a reference to the FAQ
which supplies the answer. And if you see a question being asked repeatedly,
propose it as a candidate for the FAQ.

If we are consistent in the way we respond to frequently asked questions on
this list, we should be able to reduce the overall message volume, and
increase the signal-to-noise ratio. That will benefit us all.

Re: Does struts spawn a new action class for every user?

[John Yu]

Greg,

Action MUST be stateless unless you synchronize its access.
The same single instance is used to serve all requests.

PROPOSAL: collectionProperty attribute in

[Mindaugas Idzelis]

PROPOSAL: collectionProperty attribute in 

Abstract:
A new attribute "collectionProperty" which will act like the 
current "colllection" attribute except that it specifies the property of the 
form which contains the collection thereby elimating the need for a 
 and decreasing coupling between the JSP page and the name of the 
form bean defined in struts-config.xml.

Proposal:

A common approach to using the  tag uses the collection, 
property, and labelProperty attributes to specify which bean properties to use 
to generate the  tag. This works fine when the collection is sent 
separate from the form. 

There is a problem when the collection is actually a property of the form. The 
collection attribute EXPECTS an actual collection, and will NOT accept a 
property. 

Scenario:

You have a form named "formBean" with a collection of beans under a 
property "users." You want to use the bean properties "userid" and "username" 
to render values and labels for the html options.

In order to do this, you would need something along the following lines 
of code:







Problem with this scenario:

If you notice, we must use the bean:define tag. First of all, this tag 
adds overhead: It is using reflection to copy a collection into a page scope 
variable. Also, the form now must KNOW what the name of the formBean is. 
Wouldn't it be nice if you could just tell the  tag which 
property contains the collection within the form bean? The  tag 
would call this property on the formBean associated with the Form.

Updated scenario;

This is what the jsp code will look like with the proposed change:







Proposed Change:

We would add an attribute to  called "collectionProperty" 
this property will specify what property under the current form bean contains 
the collection. The property and labelProperty attributes will function in the 
same way as they do when they are used in conjuction with the "collection" 
attribute.

Rationale:

I believe this change will give the  tag more 
functionality and make it easier to use. As well as the help in certain strut 
design patterns.
Consider the following. You have a Class called "CommonForm" which 
inherits from ActionForm. This form contains several common elements like 
State/abbreviate pairs, etc. All of your other forms inherit from CommonForm so 
they also have access to this data. The above proposal would make this design a 
lot more convenient.

I would like to hear comments as well as votes for this change. Thanks

no, there is only one instance of each action class, so yes, concurrent
calls will overwrite each other's variables.  consider it the same as a
servlet in the way you code it.

Re: Real time web page? There is a way

[Mark Ashworth]

Good day,

Listen closely as I describe how to push content to the browser. What is 
required is a servlet or the like to sit in a loop sending java script 
function updates to an iframe. Once the iframe receives the data it then 
calls an update function on the relevant page. So the solution looks like 
this:-


Browser--IFrame(A)--Servlet
-IFrame(B)

Now you are probably saying that the servlet will keep the browser busy, and 
you will be correct. That is why it is housed in an iframe, since it abides 
to special rules.

There are some special gotchas that you will need to look out for:-
1 - The servlet must be referenced by it's absolute path
2 - The servlet might not know when the user has left that page
3 - The iframe initialisation needs to be done correctly or the
page will hang on getting the data from the servlet

Java Mage

[John Yu]

Expresso and Struts complement each other.
You may want to take a look at the documentation which includes some
information on Expresso/Struts integration.

Hi,
I'm new to Struts and happen to come across Expresso too. I wonder
what're
the differences between the 2 framework? What're the strength and
weakness
of each framework?
Thank you.

Re: ActionErrors.add

[John Yu]

If I remember correctly, the errors are concatenated, not
overwritten.

What's happen if...

ActionErrors errors = new ...
(...)
errors.add("login",new
ActionError("error.login1"));
(...)
errors.add("login",new
ActionError("error.login2"));
Is the first errors is overloaded by the second error
?

Design consideration: Client side validation

[Hitesh Parashar]

Hi:

Struts puts emaphasis on server-side validations.
However, lotsa times it makes sense to do some
validations before we hit the server. 

How the client side validations should be done while
keeping the sanctity of the design principles for
struts? Is it a good practice to use use JavaScript to
do this? What are the possible ways to do this?

TIA,

Hitesh.

Re: Real time web page?

[Paul Dillon]

You can effectively push with a multipart response.  The server can send
each part whenever it wants - in response to a real-time event for example.

Some guy put together a library for doing real-time updates by pushing
chunks of javascript in the body of a long-lived response.  By putting it
into a hidden frame you could keep your main page stationary while updating
the form input elements in real-time.  Sorry I don't remember the URL.

The most robust solution would be an applet.  Is the reason you don't want
to use an applet due to presentation issues?  You can have a more or less
invisible applet that handles the communication, and use DHTML for the
presentation.

Cheers,

Paul
