Form data lost [S 1.3.8]

[Anjib Mulepati]

Hi All,

I am using large form to input data. I have some validation code as well 
as I have condition where if something goes wrong in execution of action 
it will take the user back to the form.
My problem is when validation fail or form returned from action 
execution all my form data are lost. How can I have form retain its data 
even after fail?

I am using struts tag for form and session scope for form.

html:form styleId=createAgentForm action=createAgent 
focus=agentVersion


label for=agentVersion class=formLabelbean:message 
key=label.agentVersion /*/label
html:text property=agentVersion size=10 
styleId=agentVersion tabindex=1 titleKey=title.agentVersion 
value= /

br /

   

html:submit styleClass=submitbutton tabindex=11 
value=Create Agent title=Create Agent /


/html:form


  action path=/createAgent
type=com.anjib.actions.agencyadmin.CreateAgentAction
input=/showCreateAgent.do
name=CreateAgentForm
scope=session 
forward name=createAgentForm path=/showCreateAgent.do/
/action


action path=/showCreateAgent
type=com.anjib.actions.agencyadmin.ShowCreateAgentAction
forward name=success path=createAgentPage/
/action


public class CreateAgentForm extends org.apache.struts.action.ActionForm {
..

public ActionErrors validate(ActionMapping mapping, 
HttpServletRequest request) {

ActionErrors errors = new ActionErrors();
if (getAgentName() == null || getAgentName().length()  1) {
errors.add(createAgent, new 
ActionMessage(error.agentName.required));

}
   .
return errors;
}
}

Thanks,
Anjib

I mean when form data are invalid, user get the message on top of the 
form but all data in filed get lost. It shows blank form with error 
message. i want to show previously entered data so that user can correct 
only invalid field.

could you define your intentions..?

when form validation fails you want to save the data?
what happens when form validation succeeds..do you invalidate the session?

[Paul Benedict]

I think you're losing the data because you're unintentionally creating
a new form. Make sure both actions refer to the form with the same
scope.

AW: File upload from JSP with multipart/form-data does not work on Weblogic v12c

[Peter.Keller]

I finally opened a service request at Oracle. They pointed me to Bug#13657792: 
SERVLET 3.0 FILE UPLOAD BREAKS OTHER FILE UPLOAD FRAMEWORKS

With Multipart file handling/upload now being covered as a standard nature of 
the Servlet 3.0 specification, it looks like the WLS 12c web container is 
eagerly gobbling the data before the framework gets a chance to see it.

According to Oracle support, the engineers are working on a solution.

Regards, Peter

Betreff: File upload from JSP with multipart/form-data does not work on 
Weblogic v12c

Dear list

File upload from JSP with multipart/form-data does not work on Weblogic v12c 
which supports Java Servlet specification v3.0. The same code worked as 
expected for Weblogic v10.3.X which supports Java Servlet specification v2.4. 
The same code does NOT work with Struts v2.1.8 on Weblogic v12c.

Debugging the application with Weblogic running in Eclipse I found out, that 
ALL parameters given in the JSP form (data, contextTx) are simply ignored. The 
method attribute in the s:submit tag is also ignored and therefore Struts 
always invokes the execute() method of the Struts action.

Please find the setup below.

Is this is a bug? Or is something wrong with the setup?

Thanks, Peter

Multipart/Form-Data with Struts 1

[DavidZaz]

I have a legacy application using Struts 1.2.8 and I have the following HTML
form:

html:form action=/myAction.do method=post
enctype=multipart/form-data
 html-el:textarea property=userEnteredHtml styleClass=tinyMCE
styleId=tinymce/html-el:textarea
/html:form

If I include multiple blank lines in the tinyMCE editor, the generated HTML
should be:

pnbsp;/p

However, IE posts the following HTML:

p /p

At first glance, I thought that this was exclusively a tinyMCE problem and I
posted on their forum. However, the problem goes away when I remove the
enctype=multipart/form-data from the html:form declaration. Does Struts 1
do anything unusual with the enctype multipart/form-data attribute? It does
not seem that other tinyMCE editor users are experiencing this issue (since
they probably aren't using Struts 1).

Is there any alternative to using multipart/form-data? My form does include
a file upload which is why I initially added the multipart/form-data.

[Dave Newton]

If you're uploading a file, the form must be multipart.

Which version of IE? Is it only under IE that it happens?

Yes, it only occurs under Internet Explorer. I've reproduced with IE 7 and 8.

 If I include multiple blank lines in the tinyMCE editor, the generated
 HTML
 should be:

 pnbsp;/p

 However, IE posts the following HTML:

 p /p

 At first glance, I thought that this was exclusively a tinyMCE problem
 and
 I
 posted on their forum. However, the problem goes away when I remove the
 enctype=multipart/form-data from the html:form declaration. Does Struts
 1
 do anything unusual with the enctype multipart/form-data attribute? It
 does
 not seem that other tinyMCE editor users are experiencing this issue
 (since
 they probably aren't using Struts 1).

 Is there any alternative to using multipart/form-data? My form does
 include
 a file upload which is why I initially added the multipart/form-data.

Re: Set JSP timeout in struts 1 app with multipart/form-data form

[Maurizio Cucchiara]

Hi,
what application server are you using? Did you watch application server logs?
I think the problem is related with your AS.
For instance, Tomcat have a disableUploadTimeout variable.

 Hi to all, i have a question about a situation that i have in my
 application. It's in Struts 1.1 . Basically, i have a multipart/form-data
 form in the jsp that contains 2 elements: a html:file control and a
 html:submit button . This form will be used to upload MS Access database
 file up to 800mb to extract it's data and pass it to Oracle. When i tried
 for first time, i selected the file and press the button. I monitored the
 request using Firebug extension on firefox and i saw when it sends the file
 into the request, but after a while the browser resets the connection
 (request)  maybe because the request takes too long.

 And that happens when i test it locally, but imagine in production, probably
 the upload will take more time depending of the connection, so i wanna ask
 you Struts User mail list members, if somebody knows how to specify
 something like the request timeout to avoit the browser to reset the
 request.

 Thanks in advance.

Well, i'm using Tomcat 6 for development but also i'm going to test in OAS
because that will be the production environment.

problem while reading multipart/form-data in struts

[binash]

We are using a validation framework to validate all input to our application.
This is implemented with a filter. In order to handle multipart form data
twice, we have created BufferedRequestWrapper class (as a sub class
'HttpServletRequestWrapper'). Now with this class I am able to get all the
form bean values in both filter class as well as in the struts ActionForms.
After saving the form data, i am redirecting the request to a jsp page which
includes global header page. In this included page i am getting following
error

java.lang.IllegalArgumentException: Cannot invoke Form.setCompanyLogo -
argument type mismatch.

In this page Struts try to populate(set methods) the form bean instead of
calling get methods. Here above exceptions is thrown in PropertiesUtil's
invoke method. please help to solve this problem. (we are not getting the
error if we pass Request objet instead of Wrapper object. in that case we
wont be able to get form data twice)

Wrapper class used is

public class BufferedRequestWrapper extends HttpServletRequestWrapper {

/**
 * The variable holds the Log4j instance to log the INFO, DEBUG, ERROR
and FATAL events.
 */
private static Logger LOG =
Logger.getLogger(BufferedRequestWrapper.class.getName());

ByteArrayInputStream bais;
ByteArrayOutputStream baos;
BufferedServletInputStream bsis;
byte[] buffer;
HttpServletRequest request =null;

public HttpServletRequest getHTTPRequest(){
return request;
}


public BufferedRequestWrapper(HttpServletRequest req) throws IOException
{
super(req);
this.request = req;
// Read InputStream and store its content in a buffer.
InputStream is = req.getInputStream();
baos = new ByteArrayOutputStream();
byte buf[] = new byte[1024];
int letti;
while ((letti = is.read(buf))  0)
baos.write(buf, 0, letti);
buffer = baos.toByteArray();
}

public ServletInputStream getInputStream() {
try {
// Generate a new InputStream by stored buffer
bais = new ByteArrayInputStream(buffer);
// Istantiate a subclass of ServletInputStream
// (Only ServletInputStream or subclasses of it are accepted by
the
// servlet engine!)
bsis = new BufferedServletInputStream(bais);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
return bsis;
}
}


}

following code is  there in filter

if(request.getHeader(CONTENT_TYPE)!=null  isMultiPart() // checks if req
is multipart
 bufferedRequest = new BufferedRequestWrapper(request);
 //validate the input.
 Validator.validate(bufferedRequest);
 fc.doFilter(bufferedRequest, res);
  } else { // for normal request
 //validate the input.
 Validator.validate(request);
 fc.doFilter(req, res);
 }


exception thrown in jSP page is (this jsp page is part of view page after
the execution action class which handles form data)

19:49:22,785 ERROR [PropertyUtils] Method invocation failed.

I understand it is not as clean as using struts tags, but
I drop into using scriptlets when I can't figure out how
to do it with the tags.

If you can post a small example, I will try to see if I
can figure something out.

Re: Struts 1 form data change

[Paweł Wielgus]

Hi,
maybe You can have as many forms on this page as tabs,
that would also caused that You will have 3 save buttons.
If You are worring abut performance that might be the solution.
Also You would not be worrying about which tab was selected,
only some kind of javascript that will check that user modified data on tab A
and without saving is switching to tab B - then just show him
some kind of info and question if he really want's to leave without
saving changed data.

Best greetings,
Paweł Wielgus.


2009/10/6 Paul Benedict pbened...@apache.org:
 SanJ,

 Don't worry about performance. You can't program advanced features by
 writing nothing. You'll have to do the check.

 I have the same idea in mind but how would I know tab being saved is 'A'?
 The tab last selected is the tab being saved. As I said, use a hidden
 field to tell you.

 This is where you have to modify your code :-) You'll have to take
 into account which tab was saved, and only save that tab's data. As
 you said yourself, you can't just take the entire ActionForm data.

 that you'll have to hardcode which fields belong to which tab. Once
 you do that, you can do what you want.

Re: Struts 1 form data change

[Paul Benedict]

SanJ,

This is where you have to modify your code :-) You'll have to take
into account which tab was saved, and only save that tab's data. As
you said yourself, you can't just take the entire ActionForm data.

public void execute(...) {
  if (tab being saved is 'A') {
saveTabA();
  } else if (tab being saved is 'B') {
saveTabB();
  }
}

Re: Struts 1 form data change

[SanJ.SANJAY]

Thanks Paul, appreciate that.

  I have the same idea in mind but how would I know tab being saved is
'A'? I can only detect if the tab is 'clicked or selected' not if the data
in tab is 'changed'.Hmmm ...interesting  :-).

I have three tabs in JSP with one form and only one save button for all.

Re: Struts 1 form data change

SanJ,

Don't worry about performance. You can't program advanced features by
writing nothing. You'll have to do the check.

 I have the same idea in mind but how would I know tab being saved is 'A'?
The tab last selected is the tab being saved. As I said, use a hidden
field to tell you.

Re: Struts 1 form data change

[Paul Benedict]

SanJ,

When a user selects the tab, modify a hidden form field that indicates
the tab selected. Do you know javascript? That's what you would use.

 Can you track which tab the user selected? Perhaps you can set a
 javascript variable when one is selected. The only down side here is
 that you'll have to hardcode which fields belong to which tab. Once
 you do that, you can do what you want.

Paul,

I will try that..hidden field will be a java variable. So it should be like
a boolean which toggles every user select Tab?

Thanks ..

It could be a character that represents which tab is selected. A, B, C, etc.

Re: IE ajax theme form data problem

 It's a guess, but it sounds similar to the loadingText bug due to Dojo in

 loadingText overwrites the form before the its new values are read.  Details

 Under IE (6  7), when I modify the data in the form fields and submit

Help in resetting multiple form data

[Sulabha Walavalkar]

Hi,

 

I am using 4 forms in one jsp, the reason being few select UI components 
search are common to other use cases. 

The problem I'm facing is with resetting the fields on successful completion
of any transaction.

 

One option is calling reset() method on all the forms in java script
function on onload even of body. But my application is using tiles  master
layout jsp because of which my function on body onload is not getting
called.

 

Can someone help me out giving any options to clear the data for all the
forms displayed in jsp?

 

Thanks  Regards,
Sulabha

Re: Handling form data

[Greg Lindholm]

This should help you 
http://struts.apache.org/2.0.11.1/docs/how-do-we-repopulate-controls-when-validation-fails.html
FAQ:How do we repopulate controls when validation fails .
You can use the Preparable interface to load the data from the database.
Validation does not (by default config) run on result of input.

Re: Handling form data

[Laurie Harper]

First, I should point out that an 'input' result of type 'chain' should 
work here. What makes you think it doesn't? You wont get a browser 
redirect with chaining, though, so if you want that the 
MessageStoreInterceptor can help with preserving error messages.


You can configure which methods skip validation with the excludeMethods 
parameter for the workflow and validation interceptors. Which methods 
are skipped by default varies with the different stacks defined in 
struts-defaults.xml, but assuming you're using defaultStack, it's 
input,back,cancel,browse.


I'd suggest looking at the example applications to see how these issues 
are handled there for more ideas.

What does shipping.page refer to? A Tiles definition? The 'input'

setup action.

Difficulty with submitting variable amouts of form data

[Ken Bowen]

Hi,

[I'm using struts 1.2.7  (with EL from contrib) on Tomcat 5.5.9].

I'm attempting to submit variable amounts of form data in a table following
the model of James Turner: 
http://www.developer.com/java/ejb/article.php/10931_3321521_1.
The goal is to retrieve items (user-configured alerts) from a DB, 
present descriptions
of them as lines in a table, with checkboxes for edit and delete 
added to each.

Here is the relevant part of my struts-config.xml:

form-bean name=dynamicEditAlertForm
  type=org.apache.struts.action.DynaActionForm   
  form-property name=alertsArray  type=com...AlertChoiceDesc[] /

/form-bean

action path=/SetupEditAlertForm 
 name=dynamicEditAlertForm

 validate=false
 scope=session
 type=com...SetupEditAlertFormAction 
 forward name=success path=begin.work/
/action
 
action path=/EditAlert 
 name=dynamicEditAlertForm

 validate=false
 scope=session
 type=com...EditAlertAction 
 forward name=success path=edit.alert/
/action

Successful login forwards to /SetupEditAlertForm, which is intended to 
create

the session-scoped form which will be associated with the form for choosing
(on page begin.work) the items to be edited;  The form action is /EditAlert
(see jsp below).

Here is the relevant part of the execute code for SetupEditAlertFormAction:

   ListAlertChoiceDesc alertChoiceDescs
   = alertsDBMgr.getAlertBeansChoiceDescs(); //get alerts from db

   AlertChoiceDesc[] alertLines
   = new AlertChoiceDesc[alertChoiceDescs.size()];
   alertChoiceDescs.toArray(alertLines);

   df.set(alertsArray, alertLines);
   return mapping.findForward(success);


The class AlertChoiceDesc is a vanilla Bean (with properties id, 
description, etc.)


The JSP page 'begin.work' is defined in a struts-tiles.xml definition.  The
relevant part of the page body is this:

   html:form action=/EditAlert
   table border=1 cellspacing=1 cellpadding=1
   tr thID/th ...  thEdit/th thDelete/th /tr
   
   c:forEach var=alertDesc items=${dynamicArrayForm.map.alertsArray}

   trtdc:out value=${alertDesc.id}//td
   tdc:out value=${alertDesc.description}//td
   ...
   td--/td // placeholders for checkboxes to be added
   td--/td
   /tr
   /c:forEach
   
   tr tdhtml:submit value=Edit//td

   tdhtml:submit value=Delete//td/tr

   /table
   /html:form
   
My current db contains 7 user alerts.  Debugging 
SetupEditAlertFormAction shows

that the variable alertLines contains the expected 7 AlertChoiceDesc objects
at the line:df.set(alertsArray, alertLines);

However, the JSP page 'begin.work' displays the table with only the 
header and

the submit buttons -- no data rows.

I've tried this using both
  type=org.apache.struts.action.DynaActionForm   
as shown here, and with the type

  type=org.apache.struts.validator.DynaValidatorForm
used by Turner.  The behavior is the same in both cases

I hope someone can help me see what I'm missing here.

More generally, I'm not committed to this specific pattern.  
I'll be happy to use any other technique which would allow me to present 
a variable
number of data items to the user, with checkbox (or radio buttons) 
attached, and

then obtain the user's choices.

Thanks in advance,
Ken Bowen

Submitting a variable amount of form data

[Richard Sayre]

I have a form that can have 1 to many 'Name'  text fields.  In struts
2 how do I set up the action so it can automatically grab the values
that are in those fields?

If I had 1 name field I would just put a name variable in the Action
Class and create a setter and getter for it.  How do I do this with
multiple names?

You do the same thing, but use an array of String objects as the data type:

private String[] _name;
public void setName(String[] name) { _name = name }
public String[] getName() { return _name; }

parameters interceptor and multipart/form-data

[Joshua Szmajda]

Hi all,

Whenever I set the enctype on my form to multipart/form-data (in order 
to handle some file uploads), it sporadically will stop the parameters 
interceptor from receiving any data at all.


When this happens, the log shows:
12:47:23,999 [http-8080-Processor24] DEBUG 
erceptor.ParametersInterceptor  - Setting params

as opposed to something like:
12:46:31,516 [http-8080-Processor25] DEBUG 
erceptor.ParametersInterceptor  - Setting params ferm.weight = [  ] 
ferm.program = [  ] ...


If I take off the enctype attribute, it always works fine (except for 
uploading files of course).


I've seen one other reference to this problem here: 
http://forums.opensymphony.com/thread.jspa?messageID=56353#56353

but no solution.

Any help is greatly appreciated!

Re: Form data to Vector

[Lance]

Only way to get data into a Vector is by a scriptlet or in your action.
Struts 2's OGNL has a nice way of doing this but unfortunately with S1 
we're left with dirty scriptlets in JSPs some of the time.


JSTL has a c:forTokens / that sometimes comes in handy where you 
provide a comma separated list of Strings and iterate through the elements.

The way to do this is to name your html form elements using in the

If you have a form element named myVector[3] then struts will call 
myForm.getMyVector().set(3, ?)


It is sometimes easiest to use the struts nested tags to do this

nested:iterate  property=myVector
   nested:text property=name /
   nested:text property=age /
/nested:iterate

will produce
input type=text name=myVector[0].name value= /
input type=text name=myVector[0].age value= /
input type=text name=myVector[1].name value= /
input type=text name=myVector[1].age value= /

If you are adding elements to the vector (instead of just editing 
existing vector elements), you might want to use a LazyList and a 
Factory together instead of a Vector, if you do, I can give you a bit 
more help if you need.

Hi,

I have a form with two submit buttons. One should add the content 
of a text field to a Vector (which is in the form bean?), and the 
other one should point to another page that has access to the 
Vector values.

I'd like to know how to add form data to a Vector.
Any help would be appreciated.

Thanks a lot,

MB

Re: Form data to Vector

[Balazs Michnay]

Struts does not seem to accept a Vector-typed field as a property value. The 
form simply fails to load.
I'd happily use LazyList and a Factory together instead of a Vector if it's 
easy to implement...
First I wanted to get it working with Vector, then I can easily switch to a 
different container.


In my JSP:
html:select property=vizsgalatEsOrvos[0]

In my bean:
private Vector vizsgalatEsOrvos;

public Vector getVizsgalatEsOrvos() {
return vizsgalatEsOrvos;
}

public void setVizsgalatEsOrvos(Vector vizsgalatEsOrvos) {
this.vizsgalatEsOrvos = vizsgalatEsOrvos;
}

Instantiating my Vector in the constructor won't help...
Struts should call

myForm.getMyVector().set(0, ?)

Do I need to implement this metod? Do I need to write my own setters/getters to 
do this?
How can I do this exactly?

Ok, im not sure how exactly you are using it but this is how I tend to 
do it.


In your load() action, you hit the db and generate some object for each 
row and put them into your vector.
Your jsp loops over all of the objects in the vector and displays 
inputs for each object (row)


Sometimes, you may generate a row without a serverside call (javascript) 
then post the form. In this case the set(index, object) of your vector 
will cause an IndexOutOfBoundsException. For this case, I use a LazyList 
and a factory which creates an empty object at the new index, then 
struts can populate the object with the input values.

Re: Form data to Vector

[Balazs Michnay]

This is how I need to do it: I
have a form with two submit buttons. One should add the content of a text field 
to a Vector (which is therefore in the form bean) without leaving the page, and 
the other submit button should point to another page that has access to the 
Vector values.
So I have two action classes, one for each submit button. Pressing one of them 
should therefore add one value to the Vector. I try to do this in my JSP, 
because I don't know how to call a specific bean method from the action class...
Hope I could explain it clearly...

Re: Form data to Vector

Ok, so your add button creates a new blank record on your page
Your save button posts the form to some save action which validates / 
saves to the db


Two options:
1.
When you click on your add button you submit the form
You submit the form to /add.do instead of /save.do
Your add action adds an empty row to your vector then goes back to the 
page, JSP magically draws the empty record.
When you hit save, the record is in the vector so struts can just 
populate it.

Worse user experience because of serverside hit

2.
Add button calls a javascript function which uses the DOM to create a 
row with the inputs in the same style as your jsp

No serverside hit for add
Need to use a LazyList / Factory so that when you post to /save.do, the 
empty record will be created before struts populates it.

Re: Form data to Vector

[Balazs Michnay]

OK, we're getting closer and closer to the solution... :)
It seems that only the first options works for me, because the data are held by 
two html:select controls that are created dynamically and are populated from 
the db. So when you click on the first one, the form is submitted by a 
Javascript function so that the second one can be populated with db data.

Yes, I have two different .do actions for each submit button.

 Your add action adds an empty row to your vector then goes back to the page,
 JSP magically draws the empty record.

OK, now I completely understand the logic, I just don't see how it can be 
implemented.
I really need to know where the vector should be stored (form bean?) and how 
exactly I can add an element to it (create a method in the form bean class to 
add elements?).
You say, that elements should be added in the action class, but how can I 
reference a bean method that performs the actual adding? I couldn't figure it 
out...
Of course, when you press the submit button (not the add button) all the 
previously added elements must be available...

I hope my goal is clear for you,

Thanks a lot,

MB

 In my JSP:

 }
 
 Instantiating my Vector in the constructor won't help...
 Struts should call

 myForm.getMyVector().set(0, ?)

 Do I need to implement this metod? Do I need to write my own setters/getters 
 to do this?
 How can I do this exactly?

 Sorry, it helps if i read your question fully.

 The way to do this is to name your html form elements

Re: Form data to Vector

[Lance]

ok, i hadn't realised you were a newb.
yes, vector is on your form... i'd use an ArrayList tho (Vector is 
synchronized = slower)


eg
public ActionForward execute(ActionMapping mapping, ActionForm f, 
javax.servlet.http.HttpServletRequest request, 
javax.servlet.http.HttpServletResponse response)  {

   MyForm form = (MyForm) f;

  if (add.equals(mapping.getParameter()) {
  form.getVector().add(new Record());
  } else if (save.equals(mapping.getParameter()) {
  saveRecords(form.getVector());
  }
}

try searching the web for struts CRUD examples / tutorials.

Balazs Michnay wrote:

OK, we're getting closer and closer to the solution... :)
It seems that only the first options works for me, because the data are held by two 
html:select controls that are created dynamically and are populated from the 
db. So when you click on the first one, the form is submitted by a Javascript 
function so that the second one can be populated with db data.

Yes, I have two different .do actions for each submit button.

  

Your add action adds an empty row to your vector then goes back to the page,
JSP magically draws the empty record.
  


OK, now I completely understand the logic, I just don't see how it can be 
implemented.
I really need to know where the vector should be stored (form bean?) and how 
exactly I can add an element to it (create a method in the form bean class to 
add elements?).
You say, that elements should be added in the action class, but how can I 
reference a bean method that performs the actual adding? I couldn't figure it 
out...
Of course, when you press the submit button (not the add button) all the 
previously added elements must be available...

I hope my goal is clear for you,

Thanks a lot,

Ok, so your add button creates a new blank record on your page
Your save button posts the form to some save action which validates / 
saves to the db


Two options:
1.
When you click on your add button you submit the form
You submit the form to /add.do instead of /save.do
Your add action adds an empty row to your vector then goes back to the 
page, JSP magically draws the empty record.
When you hit save, the record is in the vector so struts can just 
populate it.

Worse user experience because of serverside hit

2.
Add button calls a javascript function which uses the DOM to create a 
row with the inputs in the same style as your jsp

No serverside hit for add
Need to use a LazyList / Factory so that when you post to /save.do, the 
empty record will be created before struts populates it.

Ok, im not sure how exactly you are using it but this is how I tend to 
do it.


In your load() action, you hit the db and generate some object for each 
row and put them into your vector.
Your jsp loops over all of the objects in the vector and displays 
inputs for each object (row)


Sometimes, you may generate a row without a serverside call (javascript) 
then post the form. In this case the set(index, object) of your vector 
will cause an IndexOutOfBoundsException. For this case, I use a LazyList 
and a factory which creates an empty object at the new index, then 
struts can populate the object with the input values.

Take a look at

you will see this example of implementing a vector via use of struts 
logic:iterate in your jsp

%
 java.util.Vector vector = new java.util.Vector();
 vector.add(new Integer(12));

Empty request parameters with enctype set to multipart/form-data

[Karsten Voges]

Hi list,

I downloaded Struts 2.0.5 (beta) and started developing of a small app 
(simple form submit) on Tomcat 5.5.17 (JDK 1.5). Its working quite good 
and I am happy with both the stability and the programming model.


Unfortunately I have a problem with some requests (form submitting) 
sending no request parameters at all (empty enumeration) and setting no 
fields of my actions. This mainly happens the first time the form gets 
submitted and mainly.
When I set the enctype parameter in the s:form with enctype = 
application/x-www-form-urlencoded the form gets submitted without a 
problem. All request parameters are set (checked via 
ServletActionContext.getRequest().getParameterNames()), all fields in 
the action are populated.

But to upload files I have to set the enctype to multipart/form-data :(

I found the following questions with the same problem, but no solution 
so far:

http://www.junlu.com/msg/309344.html
http://www.archivum.info/user@struts.apache.org/2006-12/msg00622.html

I have not special interceptors in place.
When no parameters are set, the fileinterceptor is not cleaning the tmp 
files, if the request is coming in well, the fileinterceptor is logging 
as well.


Of course I could seperate the rest of the form from the upload, but I 
am not to sure if this would work either.
I copied all the code over from struts2-showcase-2.0.5 regarding the 
fileupload and it is working most of the times, but not 100%.


The strange thing, is that it mainly happens the first time I submit, 
but not the following times, but sometimes it also happens a second or 
third time.
It never happens after it worked once, so after the form submit worked 
once fine it works fine always.


Any help much appreciated.
Thanks,
Karsten.

[s2] Autopopupation of fields fails with enctype=multipart/form-data in form

[zafer Mohamed]

I have a form with the enctype set to enctype=multipart/form-data as I am 
uploading a file, the form also contains some other fields. On submission the 
autopopulation of other fields fails, but it works correctly if I remove the 
enctype=multipart/form-data. Any idea..?

Re: [s2] Autopopupation of fields fails with enctype=multipart/form-data in form

[Dariusz Wojtas]

Hi Zafer,

I would:

1) check the archives of this mailing list from the last 2 weeks,
there was a thread about fileupload issues (parameters are not always
set from such form). One of the hints was to use some magical filter
in front of the application. It is supposed to clear sth.

2) check if you have any custom filter in front of your action - the
multipart parser requires a 'virgin' request object, without accessing
any params in it prior to multiparse analysis. If you try to operate
on the request earlier - multiparser is not able to finish his task.

Make Struts set form data onto the action in same order as the form's fields

[Célio Cidral Junior]

Struts don't set the form data onto the Action in the same order in
which the fields appear in the form. For instance, suppose you have a
form like this:

s:form action=customer!save
s:token/
s:hidden name=id value=%{id}/
s:textfield name=customer.name label=Name size=30 
maxlength=200/
s:textfield name=customer.phoneNumber label=Phone size=14
maxlength=14/
!-- ... and whatever a zillion fields more --
/s:form

And its corresponding Action, which is something like:

public class CustomerAction extends ActionSupport {
private int id = 0;
private Customer customer;
private CustomerDao dao;

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public Customer getCustomer() {
if (customer == null)
customer = id != 0 ? dao.get(id) : new Customer();

return customer;
}

public String input() throws Exception {
if (getCustomer() == null)
return ERROR;

return INPUT;
}

public String save() throws Exception {
if (getCustomer() == null)
return ERROR;

dao.save(getCustomer());

return SUCCESS;
}
}

You could expected that Struts, when submitting the form, would first
set the id, then customer.name, then finally custumer.phoneNumber.
However, it does not follow that order; actually, it does set the data
in random order. In this case, the order is important because, if the
user is altering an existing customer, its id must be set before
getCustomer() gets invoked. Otherwise, the action will create a new
customer with zeroed id.

The way I built both the action and the view prevents me from writing
a lot of extra code (like getters and setters for each of the form's
field), and that's why I would like to know whether there's a way to
make Struts follow the fields' ordering when submitting the data into
the action. And if there's not, may the Struts dev team implement
that, if possible.

Célio.

That seems extremely unlikely, but they may have a different take on it. 

From my point of view it seems like your implementation is broken: if you need 
to create a Customer from an ID passed via a form or URL then you either need 
to implement Preparable or do the DAO operations in the (in your case) input 
or save methods.

IMO that functionality does *not* belong in a getter.

where the problem resides. The idea behind getCustomer() is to
abstract the retrieving of the customer object wherever it's called
along the action's code so that I don't have to care about whether
it's an existing customer or not.

Implementing Preparable does not seem to solve the problem because the
parameters are set before the prepare() method is invoked.

Re: Make Struts set form data onto the action in same order as the form's fields

[Tom Schneider]

This is an issue with the typical edit/save scenario.  The problem we are
discussing is that the domain model is needed in some form before the
parameter can be repopulated from the form save.  The technique you are
using is to reread the data from the database before the parameters are
set.  An alternative technique would be to put the domain model into a place
in the session--so on the save, you can retrieve the the model from the
session and then allow the parameters interceptor to populate the new data.
(This is referred to as detached objects in the Hibernate world)  The
advantage of putting the model in the session is that if some else modifies
the data before you reread the data, but after you have displayed the edit
page, you will not have the original model.  This particularly a problem
with a model where you are dealing with lists of domain objects.  In this
case, the edit will fail because you will be trying to set parameters on
items that might not exist anymore.  (Or you've pulled in data that the user
doesn't know about)  Therefore the safer technique is to save off the
model.  If you're concerned about putting too much into the session, you can
store the data in a cache, such as ehcache, that will store items to disk if
there are too many things in memory.  (This is the technique that we
used--we called it a model repository and we created a couple different
implementations)  I would love to see something like this out-of-the-box
with struts2, but nothing currently exists.

Thanks, I really appreciate your suggestions. However, I prefer a
stateless approach because (I think) it helps to keep things simple in
this case. Using some kind of cache between page requests is more like
a stateful approach that I would like to avoid here for simplicity
reasons.

Well, having Struts passing parameters in the order defined by the
html form would solve my problem.  :-)

Unfortunately I don't think that's possible.  The parameters get put into a
map structure, so the original parameter order is lost by the time it gets
to the servlet API.  We've run into several instances where something will
work on one app server, but break on another because we had duplicate
parameters on the url--so depending on how the app server handled it, we
would get one or the other value.  I can't imagine that any java web
framework could do this successfully.

 This is an issue with the typical edit/save scenario.  The problem we
are
 discussing is that the domain model is needed in some form before the
 parameter can be repopulated from the form save.  The technique you are
 using is to reread the data from the database before the parameters are
 set.  An alternative technique would be to put the domain model into a
place
 in the session--so on the save, you can retrieve the the model from the
 session and then allow the parameters interceptor to populate the new
data.
 (This is referred to as detached objects in the Hibernate world)  The
 advantage of putting the model in the session is that if some else
modifies
 the data before you reread the data, but after you have displayed the
edit
 page, you will not have the original model.  This particularly a problem
 with a model where you are dealing with lists of domain objects.  In
this
 case, the edit will fail because you will be trying to set parameters on
 items that might not exist anymore.  (Or you've pulled in data that the
user
 doesn't know about)  Therefore the safer technique is to save off the
 model.  If you're concerned about putting too much into the session, you
can
 store the data in a cache, such as ehcache, that will store items to
disk if
 there are too many things in memory.  (This is the technique that we
 used--we called it a model repository and we created a couple different
 implementations)  I would love to see something like this out-of-the-box
 with struts2, but nothing currently exists.

Thanks, I really appreciate your suggestions. However, I prefer a
stateless approach because (I think) it helps to keep things simple in
this case. Using some kind of cache between page requests is more like
a stateful approach that I would like to avoid here for simplicity
reasons.

Well, having Struts passing parameters in the order defined by the
html form would solve my problem.  :-)

While setting parameters in a request struts has no idea what order they 
were ordered in the originally generated form--remember that a single 
action may be called from multiple forms on multiple pages that all 
order the fields differently.  All struts has to work with is the order 
in which the fields are present in the request, which is going to be 
different for requests coming from different browsers, going through 
different proxies, etc.


If you want to guarantee the order in which parameters are pulled from 
the request, don't use the parameters interceptor and do all that 
processing yourself in your action.  If you want to use the parameters 
interceptor, but you want to ensure that a model object is loaded before 
 parameters are set, either explicitly pull the key parameter out of 
the request during the prepare call (using prepare in the stack before 
parameters), or simply use the parameters interceptor both before and 
after the prepare interceptor.


Believe us, you're not the first person to have this problem.  Believe 
us, this is the simplest solution from among those that are not broken.

Re: Make Struts set form data onto the action in same order as the form's fields

[Tom Schneider]

I think your best bet would be to break up the parameter setting into 2
parts.  (A variation on the paramsPrepareParamsStack) The first part would
set all parameters needed to load the data from the data.  Then in the
prepare, you would have the id's needed to load the data from the database.
The next part would set all the rest of the parameters.  This would be the
approach I would take if I needed to load something from the database before
the parameters are set.

 otherwise a new customer will be created with zero id. Loading the

 where the problem resides. The idea behind getCustomer() is to
 abstract the retrieving of the customer object wherever it's called
 along the action's code so that I don't have to care about whether
 it's an existing customer or not.

I agree with Dave: you're trying to do too much in your forms. You
should try to stick to a form bean that does nothing other than shuttle
data to and from the form. Your action should be invoking database
fetches and things of that nature, copying the form data from the form
bean to your DAOs, etc.

I think you're doing too much at once, and paying the price for it.

enctype=multipart/form-data gives null values for ActionForm properties

I want to upload a file as a part of a form. This requires that the

With most browsers, you cannot autopopulate a file upload field on a  
form.  The reason for this is security.  If such a thing was allowed,  
malicious web sites could have hidden frames that uploaded sensitive  
files.


For the browsers that do allow it, they will prompt and warn the user  
when submit is called.

enctype=multipart/form-data gives null values for other ActionForm properties

[Morten Andersen]

When I'm uploading a form I set the enctype to multipart/form-data in 
the jsp file.


In the action receiving the form I want to use the other properties from 
the form, but these are not set.


Example:

ActionForm has the properties:
- name (String) edited in a html:text...
- file (FormFile) edited in a html:file...

In the action I would expect to be able to get the value for name using:

actionFormImpl.getName(), where actionFormImpl is the actual ActionForm, 
but that method returns null.


Why is autopopulate not working when enctype is set as multipart/form-data?

Saving form data

[Joel Alejandro Espinosa Carra]

Hi all

I think this is a common issue, I want to know how to save the form data 
in persistent storage using serialization. I have been made this in my 
2-tier java apps without struts but  I suppose there is another way to 
do it using struts to achieve that.


Kind regards.

p.s. sorry for my english

Re: multipart/form-data and character encoding

[Martin Gainty]

Good Morning Antonisis-

If you are sending data which is of UTF-8 characterset then you need to 
configure the request e.g. request.setCharacterEncoding(UTF-8) e.g.
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/ServletRequest.html#setCharacterEncoding(java.lang.String)

If you are receiving data from a UTF-8 configured server then set the response 
as in response.setCharacterEncoding(UTF-8) e.g.
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/ServletResponse.html#setCharacterEncoding(java.lang.String)

 Martin,
 
 I' m not sure what you mean. In my Action's execute() method I get a
 request, a response and an ActionForm object. Whatever I do to the
 request or response objects, the values from the html form are already
 in the actionForm (encoded in a false way). The only way to alter the
 Strings in the actionForm is to change the method
 
 getMyString() {
  return this.myString;
 }
 to
 getMyString() {
  return new String(this.myString.getBytes(), UTF-8);
 },
 
 which I already tried and miserably failed :)

multipart/form-data and character encoding

Hi,
I 've searched the archives but haven't found any solution to my
latest problem. I have with a html:file input and a html:text
input. The problem is that request.getCharacterEncoding() returns null
and the text input is considered to be in iso-8859-1 encoding. In the
corresponding ActionForm's reset(), I have added the following line:
request.setCharacterEncoding(ISO-8859-7);

In forms that don't have a html:file input, the character set is
correct. The problem occurs only in this form and from what I 've
found it is caused by the fact that in the form declaration I have
added enctype=multipart/form-data.

Has anyone solved this problem?

we had the same problem with multi part forms. We tried everithing,
including enctype in the
form tag, URIEncoding, and request.setEncoding...in reset() method. All
theses solutions worked
fine with all kinds of requests, except for the mulipart, which is handled
in a different way.

The only solution that really worked for us was to create a subclass of
TilesRequestProcessor,
and override the handleRequest method as follows:

public class ScyllaRequestProcessor extends TilesRequestProcessor {

   public void process(HttpServletRequest request, HttpServletResponse
response) throws IOException,

ServletException {
   try {
   request.setCharacterEncoding(UTF-8);
   } catch (UnsupportedEncodingException e) {
   e.printStackTrace();
   }

   super.process(request, response);
   }

To use this processor, just change the controller entry in struts-config.xml

 Subject: multipart/form-data and character encoding


 Hi,
 I 've searched the archives but haven't found any solution to my
 latest problem. I have with a html:file input and a html:text
 input. The problem is that request.getCharacterEncoding() returns null
 and the text input is considered to be in iso-8859-1 encoding. In the
 corresponding ActionForm's reset(), I have added the following line:
 request.setCharacterEncoding(ISO-8859-7);

 In forms that don't have a html:file input, the character set is
 correct. The problem occurs only in this form and from what I 've
 found it is caused by the fact that in the form declaration I have
 added enctype=multipart/form-data.

 Has anyone solved this problem?

 Thanks,
 Antonis

Antonis,

I`m glad to know that your problem is solved. If you find
a more official solution, please let me know. But,  as you, I spent
many hours looking for it, and I didn`t find anything at all.

 Antonis,

 we had the same problem with multi part forms. We tried everithing,
 including enctype in the
 form tag, URIEncoding, and request.setEncoding...in reset() method. All
 theses solutions worked
 fine with all kinds of requests, except for the mulipart, which is
handled
 in a different way.

 The only solution that really worked for us was to create a subclass of
 TilesRequestProcessor,
 and override the handleRequest method as follows:

 public class ScyllaRequestProcessor extends TilesRequestProcessor {

 public void process(HttpServletRequest request, HttpServletResponse
 response) throws IOException,

 ServletException {
 try {
 request.setCharacterEncoding(UTF-8);
 } catch (UnsupportedEncodingException e) {
 e.printStackTrace();
 }

 super.process(request, response);
 }

 To use this processor, just change the controller entry in
struts-config.xml

Re: multipart/form-data and character encoding

[Martin Gainty]

Antonis-

Did you set the characterEncoding for the response e.g.
res.setCharacterEncoding(UTF-8)
???

Hello Martin,
 I tried your suggestion but there is a difference in my case: The
enctype in my form's declaration is multipart/form-data (I have to
support file upload). If I leave it that way, I get the same results
(no greek characters). If I change it to multipart/form-data;
charset=iso-8859-7, I get a nice exception :(

Re: multipart/form-data and character encoding

[Antonis Lebesis]

Martin,

I' m not sure what you mean. In my Action's execute() method I get a
request, a response and an ActionForm object. Whatever I do to the
request or response objects, the values from the html form are already
in the actionForm (encoded in a false way). The only way to alter the
Strings in the actionForm is to change the method

getMyString() {
 return this.myString;
}
to
getMyString() {
 return new String(this.myString.getBytes(), UTF-8);
},

which I already tried and miserably failed :)

Short answer ... you cannot.  By defintion in HTML, disabled fields are not
sent to the server, so the server has no opportunity to keep them for you.
On the other hand, if you make the field read only instead of disabled, the
value *will* be sent to the server ... but the user will not be able to edit
it.

Thanks.

Thanks Craig:
I worked for what I wanted to achieve.
Only with read-only property setting, it does not grey out input 
text field.
I have to find out what to set so that it changes appearance when 
read-only property is set.
Thanks.

Use session-scoped form or reload this value each time from the database.
