Re: Form data lost [S 1.3.8]
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?

Form data lost [S 1.3.8]
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.
focus="agentVersion">
key="label.agentVersion" />*
styleId="agentVersion" tabindex="1" titleKey="title.agentVersion"
value="" />
value="Create Agent" title="Create Agent" />
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

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

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 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

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.

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. -- Oscar Calderón SCJP 6 <http://javahowto.net>
problem while reading multipart/form-data in struts
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.
java.lang.IllegalArgumentException: argument type mismatch

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.

Uuuu it works, but... I prefer don't use scriptlet of Java... Is
there any way to use the tags like s:property or s:iterator?

I use this code in my JSP to retrieve values from
the value stack:
ActionContext.getContext().getValueStack().findValue("myValue");
I hope that helps,

How to access the form data directly?
Hi, I have an action class that implements the interfaces ModelDriven and Preparable with a bean that has data. And I have too an JSP that shows, through s:textfield, the data to the user. It works fine. But I need show in other way the data, i.e. with s:property or s:iterator... but I don't know where are this data... In the ValueStack? Any idea? sorry for my English

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.

Or
I can compare at server side, the values of fields in tabs.

Re: Struts 1 form data change
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,
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
Pawel, You are right, but, the data that I have in tab 1 contains lot of fields and is kind of different set of data. So if I just change the Tab 2 data and click save, I am unnecessarily re-saving the data of tab1 (which means firing big queries to Database) when all I need is just save set of data in Tab2. This could be a performance hit.

Re: Struts 1 form data change
Hi all, consider a story like this: lets say i'm the user, i'm loading this page, then i select tab1 and look at the data, then i select tab2 and change the data tab2_d1, then i select tab1 and change the data tab1_d1, then again select tab2 and change data tab2_d1 to it's original value, and i click "save". Now what would You like to save? In general, what is the benefit of savin only partial data? I claim there is none or very little, just look how much work You have to do to make it hapen versus normal way.

Re: Struts 1 form data change
SanJ, 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.

Struts 1 form data change
I am using struts 1. I have Adobe SPRY tabs in my JSP. There are two separate set of fields/ data in each tab. So suppose someone changes fields in Tab 2 only and save the JSP, I do not want to save the tab 1 fields also because those fields are not changed. I was wondering if there is any way I can distinguish that only TAB 2 fields are changed so that I can process only those fields in action instead of processing all the JSP form fields.

Try turning off the loading text. It's a guess, but it sounds similar to the loadingText bug due to Dojo in IE.

Help in resetting multiple form data
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
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. L. Brian Hawkins wrote: I've run into a situation that I would like to get others opinions on. The problem is with handling a form.

Difficulty with submitting variable amouts of form data
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:
type="org.apache.struts.action.DynaActionForm" >
name="dynamicEditAlertForm"
validate="false"
scope="session"
type="com...SetupEditAlertFormAction" >
name="dynamicEditAlertForm"
validate="false"
scope="session"
type="com...EditAlertAction" >
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:
List 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:
ID ... Edit Delete
...
-- // placeholders for checkboxes to be added
--
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

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; }

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?

parameters interceptor and multipart/form-data
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� but no solution. Any help is greatly appreciated! -Joshua Szmajda - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Form data to Vector
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
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,

Subject: 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.

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...
Thanks for you help,

Subject: Re: Form data to Vector
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
s 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 values.

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:
In my bean:
private Vector vizsgalatEsOrvos;
public Vector getVizsgalatEsOrvos() {
return vizsgalatEsOrvos;
}
public void setVizsgalatEsOrvos(Vector vizsgalatEsOrvos) {
this.vizsgalatEsOrvos = vizsgalatEsOrvos;
}
Re: Form data to Vector
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 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

When you hit save, the record is in the vector so struts can just

Worse user experience because of serverside hit
2.
Add button calls a javascript function which uses the DOM to create a

No serverside hit for "add"

Re: Make Struts set form data onto the action in same order as the form's fields
Hi Chris, 2007/1/25, Christopher Schultz <[EMAIL PROTECTED]>: I agree with Dave: you're trying to do too much in your forms. I disagree. There are two options that I consider acceptable for me. One of them is to write getters and setters for each form's field (just like a form bean). The other one is to write a getter for a domain bean (like getCustomer(), in the given example) and make the form read and write values from that bean via OGNL. Indeed, writing only one getter is much less work than writing a bunch of getters and setters for each form's field, specially when the form has a large number of fields. However, there's a semantic dependency between parameter settings (the customer's id must be set before any other parameter). As it's not possible to guarantee the ordering of the parameter setting in a "clean" way, I'm going to stick with the first option. Thanks to all for the help/support/suggestions/patience! ;-) Célio. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFuRdK9CaO5/Lv0PARAvrCAJ49E8WINtd8vt6wfKbXfHcIhUK/zQCeNHWI Y+X+A0efqwOtHftlT54uj8M= =P8ks -END PGP SIGNATURE- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Make Struts set form data onto the action in same order as the form's fields
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.

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.

Re: Make Struts set form data onto the action in same order as the form's fields
2007/1/25, Tom Schneider <[EMAIL PROTECTED]>: 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.

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

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

Make Struts set form data onto the action in same order as the form's fields
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:
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.
Regards,
Célio.

enctype="multipart/form-data" gives null values for other ActionForm properties
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 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? Regards Morten Andersen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Saving form data
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 -- Ing.

Re: multipart/form-data and character encoding
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)

Re: multipart/form-data and character encoding
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 :)

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 input and a
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 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

I`m glad to know that your problem is solved. If you find

we had the same problem with multi part forms. We tried everithing,

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

I tried your suggestion but there is a difference in my case: The

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 input and a
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 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

Re: multipart/form-data and character encoding
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: How to retain form data when disabling input in html:text
That is display problem. You can use css to make the field gray or red
etc.

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.

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.
