RE: multiple buttons on a form
Lachlan, I hope this helps - a bit long I know.
Below is what I have used. It shows multiple buttons
how to have data associated with the buttons. I hope
this can be understood! I've seen other similar
examples in archive butnot with the passing of data
with the button, th way i do it may be a bit flakey.
Keith.

Code for jsp - Redisplay Button Maint Button that
passed key value to form bean. property= gives names
of properties in form bean
If user presses maintButton struts calls
setMaintButton(key) on the form bean.
-
html:submit property=redisplayButton
bean:message
key=Biff1LinkList.jsp.literal.redisplayButton/
/html:submit
% String key = listItem.getLinkIDAsString(); %
html:submit property=maintButton value=%= key
%
bean:message
key=Biff1LinkList.jsp.literal.redisplayButton/
/html:submit
=
In Form bean
-
boolean redisplayButton;
boolean maintButton;
String maintButtonData;
/**
* RedisplayButton - ActionServlet calls this if it
was pressed
*/
public void setRedisplayButton(String sss) {
//dbmd(setRedisplayButton: value passed=+ sss);
redisplayButton = true;
}
/**
* Action class uses this to see if this button was
pressed

public boolean isRedisplayButton() {

tag.

In Action class
-
if (myForm.isRedisplayButton()) {
//
// redisplay page (use change selection/sort parms)
//
} else if (thisForm.isMaintButton()) {
//
// get the key value (from value= parm

if you create a submit

submit button a different

Someone must have tried that... what happens?

RE: How do you pass a data object for editing?
I agree with Ryan. An old rule from way back:- Pass Keys Round Not Data It's simpler to only keep keys across user interactions (either stored on the form or in the session). Otherwise you have 3 versions of data 1 - what's on the database. 2 - what you've saved in the session (or on the form) 3 - new values coming in from the form Not having the 2nd set of data is a big simplification. Some might say re-reading the database more frequently is inefficient. ie. Your database caching is less efficient than your server's caching of session info. Maybe - but can serializing data to the client form be faster than you DB?.

Re: How to return to the page that called the action class?
I have a generic action class that I want to set up that when the class is successful it send the user back to the page from which they came. How do I get that information? And, how would I structure my class to allow it to send the user back? We have the same propblem in our Application, and it can only be solved with a proper workflow mechanism. At the moment we use a session variable that has to be set before invoking an action, which stores the name of the page where we came from. Or we pass the name of the calling action as a parameter, so that we know where to get back. But this is all workarround, you need a workflow framework here.

RE: Help, How to display Chinese in jsp by using message tag ?
Hi, Try saving your resource file with Chinese text as GB2312 encoded text. There is a tool in the $JAVA_HOME/bin dir called 'native2ascii'. Run this against your file and you will have a pure ascii file with \u (X = hex number) to represent the double byte chinese chars. in the javadoc it specifies that java.util.Properties should be able to decode a stream of this data and convert it into 16bit unicode. If struts uses this, then your java strings should be OK. To verify that you have read in the resource correctly, I suggest writing a small java app that can write the data to screen because the character encoded will be preserved in Java. Your next problem is going to be writing data using the jspWriter. I would expect the jsp writer to also use ISO-8859-1 encoding when converting unicode java strings to a byte stream, this would completely mess up your chinese chars. You would need to change the encoding in the jspWriter to be GB2312 if this is to work correctly. What Jeff says is also correct, you would need to specify the encoding used in the http headers. If neither of the two suggestions above work, then your other option is to sub-class the relevant code and override the methods that do the encoding with your own. But then you are probably entering a whole world of pain :) Sorry, I cant be of more help, I have only ever done double byte i18n work on normal apps and not web apps.

Have you tried putting the contentType in the JSP page directive like I had previously suggested? The html spec at http://www.w3.org/TR/html4/ section 5.2.2 says: To sum up, conforming user agents must observe the following priorities when determining a document's character encoding (from highest priority to lowest): 1. An HTTP charset parameter in a Content-Type field. 2. A META declaration with http-equiv set to Content-Type and a value set for charset. 3. The charset attribute set on an element that designates an external resource. Therefore, if your web server is sending the content type as part of the HTTP header, your meta tag will be ignored.

Struts intermittently not working after startup
I've been developing my first real Struts application for last several weeks and things have been going OK. But I reached a point (about Sunday) where the web app now doesn't always work correctly, in that it give errors like: Error 500: No action instance for path /findEntity could be created and other objects that should have been instantiated but arent'. If I restart the server a few times the web app works again. There is nothing in the log to suggest that the web app startup is failing (all action mappings seem to be added ok). It's only when I click on a link that I see the problem - Struts trys to forward me to appropriate Action but can't find it. The errors just sem to have appeared as my web app grew to a certain point but I only have about 30 mappings in the config file - I can't see that's a limitation. I have a colleague whose Struts app is now also exhibiting same problem. Any ideas please?

RE: How do you pass a data object for editing?
Tom, In that case as you are doing now is the best way. Maybe store the key on the form so you can check the key on the incoming form matches the key of the data held in the session (to guard against bugs hacking). Then (big pain) - before updating check the data on the DB is the same as what you originally saved in the session (guard against intervening updates (optimistic locking I think they call this)). This involves a lot of code! --- There is another way which I prefer - but not so often used. eg. Opening a bank account online involves many forms. On your customer account tables have a status field. Values:- INCO - Incomplete data. ACTV - Active BLKD - Blocked DEL - Deleted Each form writes the data to the DB as INCO indicating data from a multi-form interaction. After all forms are complete final validation is done the status set to ACTV. Most functions treat INCO the same as DEL - ie. ignore it - the INCO value isn't a lot extra to add. Advantage - in a complex long interaction every submit saves data on the DB - so lost sessions, internet problems don't lose the users data. Disadvantage - possibly large amounts of INCO data from people messing about - extra hits on database. Any use?

RE: How to extract multiple columns of data in an logic:iterate tag ?
I had to do the same thing. My bean model is Iterator. Everything WORKS.
Use nested iterate tags on the same name, BUT! you must call previous() in
nested iterate.
logic:iterate id=dummy name=groupModel
trjsp:setProperty name=groupModel property=back
value=/
logic:iterate id=dummy2 name=groupModel
length=2
td width=49% valign=top...
jsp:getProperty name=groupModel
property=procDescription/
/td...
/logic:iterate
/tr
/logic:iterate
Please notice:
1. Usage of length attribute in nested iterate;
2. Call to hack setProperty/back, which does something similar to
previous().
I think this SHOULD be fixed by Struts writers:
...EVERYTHING IS APPROXIMATE:
IterateTag.java...
boolean dontNext;
Tag tag = findAncestorWithClass( this, IterateTag.class);
if( tag != null tag.getName().equals(getName()) ) { // we are in
nested iterate on the same name
dontNext = true; // parent tag also hasNext, otherwise how could we
come here?
}
... if( ! dontNext) // add this line
... next()

Subject: How to extract multiple columns of data in an logic:iterate tag ?
Assume that the ActionForm has the getter for the below myhashtable that
returns a Map.
Assume that the .value returns an Array of Strings (or whatever)
I want to build a table with 4 columns in it with the logic:iterate .
I copied the below code from the STRUTS Developers Guide:
logic:iterate id=element name=myhashtable
Next element is bean:write name=element property=value/
/logic:iterate
Assume that a typical record is like:
Map.key = myKey
Map.value = [ myvalue, mydesc, myotherdata ]
But, how do I get the 0th, 1st, 2nd, etc. columns data out of the .value?
Does this work?
logic:iterate id=element name=myhashtable
Next element key is bean:write name=element property=key/
Next element value 0 is bean:write name=element property=value[0]/
Next element value 1 is bean:write name=element property=value[0]/
Next element value 2 is bean:write name=element property=value[0]/
/logic:iterate
What if .value was a Class like
public class myRecord{
.getValue()
.getDesc()
.getOtherData()
}
How would you call the getters to get the data?
All help is appreciated.

RE: ActionForward to anything other than a jsp
You can try something like below where the local action mapping maps to an
action.
forward name=success path=/detailAcct/
//return to a chained action
//Note: if for some reason the success is changed from a mapped
//action to a jsp page expect some nasty errors here.
ActionForward actionForward = mapping.findForward(success);
ActionMappings mappings = mapping.getMappings();
String returnPath = actionForward.getPath();
ActionMapping finalMapping = mappings.findMapping(returnPath);
EraAction finalAction = null;
try {
Class clazz = Class.forName(finalMapping.getType());
finalAction = (Action) clazz.newInstance();
}
catch (Exception e) {
cat.warn(Could not find chained action: + e.getMessage());
cs.setAttribute(accountForm,formInstance);
return mapping.findForward(error);
} //end try catch
return
finalAction.perform(finalMapping,formInstance,request,response);

Subject: ActionForward to anything other than a jsp
Hi:
I have read the archives and have seen some posts and responses to this
question, but was hoping something more definitive might be posted.
Within an ActionA, I would like to forward to another ActionB to
continue processing. Sounds reasonable. So, I look up the javadoc and
see the section about ActionForward and think okay I would simply do the
following in the first action
ActionForward forward = new ActionForward(/ActionServlet/ActionB);
return forward;
Well, so far no luck to say the least. I seem to always get 404 errors
that the page can't be found. I have seen a post about bypassing the
ActionForward and using the request.getRequestDispatcher and have not
tried that yet since it seemed so logical that the ActionForward method
should work.
No go, the only workaround I found was to have the forward to a .jsp
page that did a jsp:forward to the actual action.
Can someone please let me know. Can an Action forward to another Action
instead of a JSP page and if so why does the above method not work?
Thanks for any guidance.
Scott

Problem with Tomcat 3.3 and Struts 1.0
Hi! I'm new to struts and need help to get the examples running. I've downloaded and installed a fresh Tomcat 3.3. Then I installed struts 1.0 by copying all struts-*.war in the webapps-directory of tomcat. After restarting tomcat, struts is almost working: * http://localhost:8080/struts-documentation - work * http://localhost:8080/struts-blank - work * http://localhost:8080/struts-example - work * http://localhost:8080/struts-template - work * http://localhost:8080/struts-upload - work * http://localhost:8080/struts-exercise-taglib - 75% The link to /struts-exercise-taglib/bean-cookie.jsp causes an org.apache.jasper.JasperException with root cause: java.lang.IllegalAccessException. The link to /struts-exercise-taglib/logic-match.jsp causes an javax.servlet.ServletException: No getter method for property value of bean cookie with root cause: javax.servlet.jsp.JspException: No getter method for property value of bean cookie. But the best is the link to /struts-exercise-taglib/logic-compare.jsp. It kills tomcat :-(.

how to deal with Variable form elements in struts
Hi, I have a form that looks very similar to the inbox in Yahoo or HotMail. The number of checkbox is varying and so are their names. How to assign their values to the Form Bean property? Currently I've been using a normal input html form tag like follows. input type=checkbox name=chk_%= I % and in the Action Class I'm using the request object to go through all the form elements using getParameterNames and finding out the checkboxes and getting the checked row. Can some one through light on how to go about doing the same using the Struts frame work. --Shashi.

Re: multiple buttons on a form
I suggest that you create a function Javascript called for the buttons, inside of the function you records one hidde-field before calling submit with a parameter passed for the function, for example, then you I can treat several submits. - Original Message - From: Kiet Nguyen [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] Sent: Thursday, December 13, 2001 12:48 PM Subject: RE: multiple buttons on a form The image submit from strutsx seems to work for a submit with an image.

re: How to return to the page that called the action class?
There are a couple options I can think of: 1. use request.getHeader(Referer) 2. add a property to your generic class that holds the return link. Then have the calling class set it. 3. you could use javascript to back up, but that is ugly...

re: forward to jsp or to do ?
Correct, if you forward to a jsp, it will display the compile jsp servlet. If you forward to a do, then it will look for that action in your actions-config.xml and execute the appropriate action class. This allows you to chain actions together.

Re: Mixing Struts with XSLT
It makes sense to me and would like to know if there is an answer as well. This tackles one problem. What about the return? You have to generate XML again and than send it through the loop. Sandeep --- Dave Makower [EMAIL PROTECTED] wrote: We are currently using XML with XSLT in JSPs, in the following manner, and we'd like to integrate this approach with Struts: We use a custom tag (similar to the x:transform tag slated for inclusion in the standard JSP taglibs) that applies a stylesheet to XML included in the body of the tag. This way, we can use Java and JSP inside the transform tag to generate XML, and have our HTML developers create XSLT stylesheets that create the appropriate look for the data represented by the XML. A further advantage of this approach is that we can start by including static XML in the JSP as a stand-in for the dynamic data, so that the HTML developers can create their stylesheets in parallel with the Java developers doing the work to generate the XML dynamically. Now that we're considering moving to Struts, we'd like to be able to let our HTML developers use the Struts html taglib within their stylesheets to generate HTML form elements. But that would require that after the transform tag is interpreted, the results are passed again through the JSP interpreter in order to replace the Struts tags with the appropriate HTML form elements.

RE: Design Help
James,
I was reading through the archives when I came across the below post. If
one follow the design as you have shown below, dose the Delegate get stored
in the form? If it does then does one reference the DAO via the delegate
with a nested type syntax in the view/JSP?
So if I have a Delegate, which in you example does a viewall, I first
create the delegate, create the DAO and populate it and then store the
Delegate in the form with some standard setter and getter method:
FORM:
public void setDelgate(Object d) {
this.delgate = d;
}
public Object getDelgate() {
return this.delgate;
}
Then in the view how do I reference the values in the DAO?
Is it just something like:
bean:write name=ViewAllFrm property=delegate.dao.value/
Where dao is the Data access object, and value is a getter in that object.
Is this the correct flow or am I missing something?
Thanks in advance.

Todd G. Nist

Subject: RE: Design Help
1) The relationship is a starting point. Basically, I would not pass an
ActionForm to my business delegate (RentalBean). Doing so ties that
delegate to the web interface. If you were wanting to create a Swing client
in the future, you would have to create seperate business delegates for it.
Try to abstract your business delegates from your view ( see code below ).
2) Use a constructor that requires no params, but provide 'public void
init(...)' params to initialize the state of your bean.
3) Depends on the scope of the application. I usually provide several
different applications, all depending on the business cases (admin app, web
user app, swing app, web services for b2b,...).
4) Start off with a base data access class that has general methods. The
methods should provide a way to create jdbc connections and close
connections, statements, and result sets. You can also have query builder
methods in this class that don't tie it to any single use case.
If you are wanting the application to scale upto EJB in the future, you are
best to use delegate objects like you are doing (RentalBean).
If you are wanting to use an Action class for every use case ( adding a
rental, editing a rental, viewing a rental, deleting a rental), then you
don't need to the action property . If you are wanting to use one class,
then use the 'action' property in the request, this is how id did it below.
The data access object (RentalDAO) should be an interface. You should use a
factory that uses a JNDI value to select the DAO object. This allows you to
change databases by just modifing a value in the web.xml file and
redeploying your app. I wont go into this, but check the java petstore app
(1.2.1) for examples.
With the following code, only the BaseAction, RentalForm, and RentalAction
are tied to the web client and struts. The business delegate
(RentalDelegate) and the data access object(s) (BaseDAO and RentalDAO) can
now be used with other clients (web, wap, swing,...).
Lets rewrite some of the pseudo-code you sent:
-- Code for BaseAction.java --
public abstract class BaseAction extends Action {
//Don't use class variables in Action objects. These are not thread
safe.
//protected String action=null;
//provide this method just in case any of your subclassing actions want
to do some pre-initialization processing.
public ActionForward prePerform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
//could do custom authentication or something else.
//base implementation returns null.
return null;
}
//this is good. I do this on all of my projects. Also got the idea from
Ted Husted and a few others on the list.
public abstract ActionForward performAction(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException;
//proxy method
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
//WE CANT DO THIS BECAUSE Action OBJECTS ARE NOT THREAD SAFE.
//Find out what we are doing (Create,Edit,Save,Reset, Delete, etc.)

RE: Struts Design question
But my beans already contain the validation! Besides, performing the validation in the ActionForm is effectively tying business logic (data validation) to the web framework dontya think? Well, I put data type and required field validation only in the bean. Validation that is more advanced than that, or based on business rules should be in your app server (if you have one), or in the action object. While the response might be OK in a specific solution, I think it is, in general, the wrong partitioning of the validation issue. The questioner was more on the correct track. To understand the more general case, consider the case where a company has a database(s) and is developing multiple applications, some may even be developed by 3rd parties. How do they look at the data validation issue? Any DB administrator will tell you HE/SHE is responsible for the DB integrity, not the (irresponsible :-) app developers: - The data integrity issues need to be defined by those who really understand and are responsible for them. This includes business data rules. - You don't want to replicate the validation in multiple applications. - You don't want to have to change multiple applications and the database simultaneously if there are changes. - etc., etc., etc. Note that this doesn't mean ALL validation is associated with the database, just that which relates to the data model and the business integrity of the data base. If one app requires certain data, another app different data, and the database doesn't care, then it is the application responsibility. To address this we defined a set of objects which front the database. They worry not only about validation, but also things specific to the database (e.g. query language), connection pooling, etc. To work well with web applications these objects need to have a validation interface that lets you provide the total set of new (string?) data and allows the object to return field-specific and object-general error information. This is also a good place to place the common business data rules (not application rules) so that all applications use one common set, maintenance is consistent, etc. In VERY simple cases you could merge this with Action classes, but generally there are significant differences, no 1-1 relationship, etc. Frank Lawlor Athens Group, Inc.

- Only the standard forwardTo call is used.
- All transfers of control use forwards name=...

there must be better terms I'm sure.

RE: multiple buttons on a form
This is how I did it, and it seems to work well:
In my form I have the following:
html:submit property=addAdd/html:submit
html:submit property=saveSave/html:submit
html:submit property=deleteDelete/html:submit
In my action, I check for the existance of one of these properties and act
accordingly. For example,
String value = request.getParameter(add);
if (value != null) {
//do something...

Re: Struts/FOP
Cocoon and Struts are different. Since I wanted to avoid server side production load issues (of lots of XSLT) I emit XML from JSP to browses. And the browses then do the XSLT FOP-like for me. This way salability is flat, as more users use it, each user uses its own XSLT on client side. (For older browser, need JavaScript for XSLT, but new ones do XML just fine) (And I also use RTF instead of PDF, since RTF reader is already installed on all OSes, and Adobe PDF has to be installed and for other reasons I avoid Adobe . And I do not use all the FOP tags, just a few like table and row). Vic (promo: my book at basebeans.com talks about XSL in a chapter) [EMAIL PROTECTED] wrote: I would be interested in your approach.

ActionForm and ActionMapping Access From JSP page
Hi, What's the *best* way in struts to access ActionForm instance (may be in request or session scope) from a JSP script (note, not using struts tags, e.g. for displaying a label that is using data from ActionFrom cache ) ? Similarly what's the best way for a JSP page to access ActionMapping instance ? Thanks in advance. Jerry
load() exception
Not sure if you managed to solve your problem but I was having a similar
problem getting struts to work on Websphere v3.5.4
I ended up doing the foloowing to get it to work:
in the .xml (struts_config and web) and .dtd files change the word
PUBLIC to SYSTEM
extract the .dtd files from the struts.jar to
servlets/org/apache/struts/resources
use the 1.0.1 version of jaxp.jar (and not v1.1). Webspehere 3.5.4 does
not seem to work with jax v1.1 and if anyone knows of a patch for this
or if v4 resolves this it would be much appreciated.
use parser.jar
in the struts_config.xml and web.xml files I needed to explicitly point
to the relevant .dtd file (eg !DOCTYPE struts-config SYSTEM
file:/{local
machine}/servlets/org/apache/struts/resources/struts-config_1_0.dtd).
This was not documented in the apache site's installation steps but I
found a reference to it in one of the mail archives. Obviously I will
be changing this to point to a relative path.
Also, I did not patch the ActionServlet class as recommended in apache's
installation steps as this caused a parsing error.
Please let me know if this helps.
Regards,
Andrew

Apologies for following up a user-type question with another one, but in
the interests of (brain) bandwith I don't read the user list. Please
forgive me, I won't do it again :-)
If this approach is used, populating the form bean before the form is
displayed, then it means that hitting a Reset button will, rather than
clearing the form, clear out any user modifications and re-fill the form
with the values that the bean was populated with in the previous step.
Now, I know that this is the expected, or even required behaviour from the
point of view of HTML. However, when I had one site going through testing,
the tester complained that a particular form was broken because the reset
button kept on filling in the values instead of clearing them. In this
particular case, it was clear that what was required was not a reset
button, but a clear all the fields button.
So, getting to the point (eventually), I know that it's possible to do this
server-side, by having a button which will just cause the form bean to have
all its properties set to null and redirect back to the input page.
However, is there a way to do this client-side?

Subject: form initialization
Greetings!
I have a dynamic form which needs to be initialized from the database.
If I put code to initialize the attributes in the default constructor
of the form bean, all this happens with no problems - the form is
displayed with the proper values. My problem is that the form bean
needs some of the request parameters from the calling jsp page in
order to properly initialize its fields. What is the preferred way of
form bean initialization and how can it access request parameters at
initialization time? I used a couple hidden form fields which the jsp
page initialized to the corresponding request parameters, but this
does not take effect until AFTER the constructor is called. Any help
would be much appreciated.
This type of question is really more suited for the STRUTS-USER list.
The design pattern I prefer is exemplified in the Struts Example
application -- use an Action to set up the form bean *before* the form is
displayed.
In the example app, note how an Edit Subscription transaction is
handled:
* The /editSubscription action is called to pre-fill the
SubscriptionForm bean and place it in request scope. If you
need values from the request that triggered this, they are
accessible to the Action and it can call setters as needed.
* This action forwards to subscription.jsp which shows the
pre-filled-out form.
* The submit goes to the /saveSubscription action which
updates the database (assuming successful validation).
TIA!

I had to do the same thing. My bean model is Iterator.
Everything WORKS.
Use nested iterate tags on the same name, BUT! you must call
previous() in
nested iterate.
logic:iterate id=dummy name=groupModel
trjsp:setProperty name=groupModel
property=back
value=/
logic:iterate id=dummy2 name=groupModel
length=2
td width=49% valign=top...
jsp:getProperty name=groupModel
property=procDescription/
/td...
/logic:iterate
/tr
/logic:iterate
Please notice:
1. Usage of length attribute in nested iterate;
2. Call to hack setProperty/back, which does something similar to
previous().
I think this SHOULD be fixed by Struts writers:
...EVERYTHING IS APPROXIMATE:
IterateTag.java...
boolean dontNext;
Tag tag = findAncestorWithClass( this, IterateTag.class);
if( tag != null tag.getName().equals(getName()) )
{ // we are in
nested iterate on the same name
dontNext = true; // parent tag also hasNext, otherwise
how could we
come here?
}
... if( ! dontNext) // add this line
... next()

Subject: How to extract multiple columns of data in an
logic:iterate tag ?
Assume that the ActionForm has the getter for the below
myhashtable that
returns a Map.
Assume that the .value returns an Array of Strings (or whatever)
I want to build a table with 4 columns in it with the
logic:iterate .
I copied the below code from the STRUTS Developers Guide:
logic:iterate id=element name=myhashtable
Next element is bean:write name=element property=value/
/logic:iterate
Assume that a typical record is like:
Map.key = myKey
Map.value = [ myvalue, mydesc, myotherdata ]
But, how do I get the 0th, 1st, 2nd, etc. columns data out of
the .value?
Does this work?
logic:iterate id=element name=myhashtable
Next element key is bean:write name=element property=key/
Next element value 0 is bean:write name=element
property=value[0]/
Next element value 1 is bean:write name=element
property=value[0]/
Next element value 2 is bean:write name=element
property=value[0]/
/logic:iterate
What if .value was a Class like
public class myRecord{
.getValue()
.getDesc()
.getOtherData()
}
How would you call the getters to get the data?
All help is appreciated.

Re: What is the placeholder character for ActionError?
What is the placeholder character that will get replaced in the error
message string?
The placeholder is {D}, where D is a digit between 1 and 5.
In other words, you might have something like this in your
ApplicationResources.properties:
error.basic=An error occured, here is some info: {0}
This allows you to add one extra bit of info to the error text. If you want
to add two, do this:
error.detailed=An error occured, here is some info: {0} br/Error code:
{1}
You would have something like this in your ActionClass:
ActionErrors errors = new ActionErrors();
// to report the first error (error.basic)
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(error.basic, e.toString()));
// to report the second error (error.detailed)
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(error.basic, e.toString(), BitRot in ActionClass));
// Report any errors we have discovered back to the original form
if (!errors.empty())
{
saveErrors(request, errors);
return(new ActionForward(mapping.getInput()));
}
Make sense?

Newbie question about caching data for forms
Hi all, I've been reading through a lot of the Struts info available on the web in various places, and I have a question I'm hoping one of you more experienced folks can answer. There is something simple that I think I'm still not getting. How, using the tag libraries of Struts, can I do the following: 1. If this is the first time that a user has visited the page, then the form isn't pre-populated with any values. The user just types in his/her desired form field values and hits submit. 2. If the webapp knows what the values should be, then the form is first pre-populated with data for the user to edit (e.g. if the user was on that page before but validation failed, so all the fields are pre-populated with the user's previously-submitted data). I think that somehow the html:form and/or bean:parameter tags are where I need to look. To make this more concrete, think of your standard login page. When the user first hits the app, they type in their username and password on some login.jsp page. If they screw up their password, they'll get sent back to the login.jsp page, but now to be nice we'll have the username field pre-populated. That was a simple example; extend it to complex forms where there is a lot of data to keep track of and multiple paths back to the form. In other words, what I'm looking for is the best (or at least typical) idiom for using the struts tag libraries and associated classes to capture the user data and bundle it not only for processing by its action but to also hand that bundle back to a JSP page if necessary. If somebody could show me a simple example of what the JSP page and appropriate fragments of some associated form and action class, I'd be muchly appreciative. I'd probably also begin to feel a little more clueful than I do at the moment... Thanks! Reid - Do You Yahoo!? Check out Yahoo! Shopping and Yahoo! Auctionsfor all of your holiday gifts!

You can have one FormBean having the scope set to session (in struts-config.xml), used accross all the JSP pages. In the JSP pages use the jsp:useBean tag to have the same FormBean in the session. In all the JSP send the action to a single action class. To distinguish between different pages in the Action Class have a session variable to identify the page number and set it in each page.

How to solve it???
Hello,
This is a plain JSP - HTML code:

%
for(i=0; iobjUsers.size(); i++){
tmpuser=objUsers.getUser(i);
%
trtd input type=checkbox name=user value=%= tmpuser.getUserId()%
%=tmpuser.getUserId()%td/tr
%
}
%
After running the above code and view the html source then i can see:
trtd input type=checkbox name=user value=chiru chirutd/tr
trtd input type=checkbox name=user value=deva devatd/tr
trtd input type=checkbox name=user value=ravi ravitd/tr
trtd input type=checkbox name=user value=selvam selvamtd/tr
---
Now I want to convert the above code to struts. For that how to design
my form class to map the values from HTML to Form class and action
class?
Because Its array of checkboxes. How to write set and get methods in the
form class.
Pls help me.
