Re: FileUpload: Stream ended unexpectedly

Re: preview form
select does support readonly , unfortunaely it does not understand readonly attribute, but only disabled -Dan - Original Message - From: Janice [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, February 16, 2004 1:03 PM Subject: preview form Hi Gang, I have a form that the client would like to be 'previewed' before users can submit. The plan is to have a form with a button that takes the user to the exact same form, but with all the form elements set to readonly. From there the user can go back to the editable form or can submit. At least that's the plan. I'm open to other suggestions, especially of the 'best practices' variety. I would have liked to display the form information on a non-form looking page, but the problem I have is the drop-downs which have a very different value from label. I don't want the preview to display something like: person: 12353 instead of person: Jane Doe So I guess I need the drop-downs, unless you all have a workaround? My immediate problem is that html:select / doesn't support readonly... what else can I do?

Re: problem with dbcp and database restart
Meissa, When your database restarts, all your dbcp connections (in the pool) become staled connection. In order to resolve this problem, dbcp needs to do a ping to database server to make the connection is still up before giving to your app. Looking into dbcp configuration doc, it should have a param you can setup (something like QueryString) where it should be a select statement to a database table. You many need to setup a dummy table just for this purpose. Hope this helps. -Dan - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, July 09, 2003 7:36 AM Subject: problem with dbcp and database restart hi all, I have a problem with my configured datasource using dbcp.

Re: Initialize Struts form with request parameters
Adam's answer is absolutely correct, however let me add more details to make your job a little bit easier. 1. Create and action called loadTrainee.do and associate this action with your form. with a forward to chooseTraineePage.jsp 2. Invoke chooseTranies.do?traineeId=, struts, will call the action in 1 and automatically populate your form's traineeId for you 3. In action1, write some code to use traineeId to fill name, struts will then forward your form to chooseTraineePage.jsp to display In summary, you need 2 actions, one to to load the form and the other one is to manipulate the form Hope this helps -D - Original Message - From: Adam Hardy [EMAIL PROTECTED] Newsgroups: Struts Sent: Tuesday, July 01, 2003 7:26 AM Subject: Re: Initialize Struts form with request parameters This would happen automatically if you access the JSP via an action mapping in your struts-config.

You can configure Struts to ad HTTP no-cache headers to every response :
in struts-config.xml :
controller nocache=true/
You can add some HTTP directives to your JSP (or tiles layouts) like this
:
head
meta http-equiv=expires content=now
meta http-equiv=pragma content=no-cache
meta http-equiv=Cache-Control content=no-cache
/head
Nico.
Before you send any data in the response you can
Send the following thru your response object:
%
response.setDateHeader (Expires, 0);
response.setHeader (Pragma, no-cache);
if (request.getProtocol().equals (HTTP/1.1)) {
response.setHeader (Cache-Control, no-cache);
}
%
Note, however that users can still go back in history
And resubmit their data. Browsers maintain history list
And unfortunately they do remember form data too. So if
Your user submitted a request and then clicks back button,
The browser will ask him/her if he/she wants to resubmit
the data? I saw a note somewhere in Ted's (I think) book
about how you can prevent this kind of submission on the
server side but have not explored that further. Now I
can't even remember where I saw it.
The gist of it is that before you send the form to be
submitted by the user you stamp it, and remember what is
it you still expecting from the user inside the Session
context. If user submits the form with the right stamp
the request is processed, otherwise you can tell the user
to stop resubmitting the same request.

Ok this has me stumped...
the down and dirty:
formBean has HashMap called fooMap
fooMap has keys that bring back beans of type BarBean
BarBean has properties someCode , someDescrip
Now I want to iterate over this map and create the properties based on
the properties in BarBean and be able to update this form which will
then update the underlying BarBeans in the map.
(Ignore the part that I know that's a hassle about the reset method and
making sure Map exist there).
c:forEach var=beanInMap items=${formBean.fooMap}
someCode: html-el:text property=/br
someDescrip: html-el:text property=/br
br
/c:forEach
the text will display fine in the form with:
someCode: html-el:text name=beanInMap property=beanInMap.deptCode /
but when the form submits all the bean property values are null ( in the
reset if it matters for testing i'm just creating a few maps with empty
BarBeans in the map).
I'm stumped.. any help much appreciated.

Re: file upload and unicode
Just upload the file as normal binary file.
When you read this file at the server side, make sure to
read it with correct encoding of unicode type
(like UTF8,UTF16, etc)
You probably need to allow the user to enter
the upload file encoding type, and pass along
this info to server

Subject: Validator Framework Questions
Hello!
Reading a Struts book I wanted to give the validator framework
a whirl. Since it's poorly described in the book I checked out
Struts website. I wonder if when we speak about automatic form
validation, then if do we mean the validator from the website
http://home.earthlink.net/~dwinterfeldt or has another
validator been integrated into Struts. How doI setup an
automatic form validation?
I've build a form with 3 fields called field1, field2, field3
and a submit button. I've defined the validation rules in the
validation.xml file, but this thing just doesn't work. Below
my setup.
my validation.xml looks like this:
form-validation
formset
form name=postTestForm
field property=field1
depends=required,maxlength

Re: adding / creating new collection elements in a form
I just implemented myself, so let me throw a shot at this.
In my case, I make my action derived from LookupDispatchAction
which can handle multiple button submission handlers.
One of the button is called something like addRow. When you hit this
addRow button, struts will repopolate what ever on your screen and dispatch
it
to your addRow handler where you can add new empty row to your collection
and forward back to your screen.
regarding your out of index problem, I would suggest to use common
Collection
ListUtils.lazyList. Here is an example a lazy collection in a my form
private List gradeViews = ListUtils.lazyList(new ArrayList(), new
GenericFactory(org.glvnsjc.view.StudentGradeView));
//there is no direct setXXX, call getXXX first and populate the object
// lazy list takes care all dynamic allocation
public StudentGradeView getGradeView(int index) {return
(StudentGradeView) gradeViews.get(index); }
public void removeAllGradeView() { this.gradeViews.clear(); }
public List getGradeViews() { return this.gradeViews;}
Please look up GenericFactory in the maling list, I dont want to repost it
If you dont know LookupDispatchAction yet, learn it. It has the magic that
I cant live without
Good luck!!!

Subject: Re: adding / creating new collection elements in a form
Perhaps I was not making myself clear when I first posted this.
I know how to write the javascript, I know how to use struts
nested/logic tags. What I was looking for when I posted was
a solution whereby I could add new elements to a collection
in a form. Not update existing elements, thus increasing the
size of a collection based on properties from fields that
were added by client side scripting.
I've not been able to find a solution to this within the mailing
list. But I would like to the following.
I have a page with a collection of fields which are populated by
a form (via it's collection). I also have a button which would
allow the addition of a new row. (hopefully)
Name Descrip
[ xy ][ foo ]
[ ab ][ bar ]
Add
(1) I would like to have the add button add a new pair of text
input fields each time it is clicked. (2) I would like it if
clicking add did not make a request to the server this being the
case it suggests some kind of client side javascript adding the
new fields.
The problems of course with this are the following.
(1) client side code won't be able to utilise the struts tags
and as such I won't know what values to set the appropriate
input text element attributes to.
(2) It is highly likely that even if I solved problem (1) that
it would result in a IndexOutOfBounds exception, or just not
bother with the properties from the new fields.
Has anyone else solved this? Does struts have a mechanism for
dealing with this? I'm fully aware of nested/logic tags but
if they are the way I can't see how.
Suggestions would be appreciated, Thanks!

Subject: how to submit Unicode text in Struts/JSP?
hi,
I'm trying to submit Unicode encoded to a search engine through a web
client
developed is Struts.
Each JSP page of the Web client sets the page encoding using the following
HTML statement:
meta http-equiv=Content-Type content=text/html; charset=utf-8
After the submission, in the Action servlet, I compare the request with
what
I would expect to receive as a submission:
It goes like this:
String request2 = new String(\u017Eivot);
if (request2.equals(_request)){
System.out.println(request OK);
}
They are not the same and I don't know why. When request2 is submitted
directly to the search engine there is result received back.
How to submit successfully Unicode text to the server?
I'm using
J2SE 1.4.1
JBoss 3.0.4
Tomcat 4.1.x
thanks,

Like other framework components underneath Jakarta, there are versions that have this bug or that bug. In general however, I have found the Validator to do everything that it was designed to do. I can't explain why some have had more trouble than others; it might just be the version of the software they were using at the time. Like many other facets about Struts and its related technologies, it can become unyielding at times, but is manageable. So, for those of you who have yet to try it, don't be afraid. Get yourself a book that covers it, read the docs, search the lists. Whatever you do, don't reinvent the wheel. For lexical or syntactical validation (whether client or server side), the Validator gives you a development boost. You just have to take the time to learn how to use it.

I've had no issues generating both the client side and server side validation, and its saved me a lot of work. Like others i think it would be nice to define form beans and validation rules in the same place but I like it as it is, unless anybody has any alternatives? One thing to consider is that Struts validation is based on commons-validator which reads its own xml config file. Moving the validation configuration to struts-config.xml would require us to do all the validator setup in Struts rather than leveraging the commons-validator code. David Thats my 2 pence..

Your probably better off having an action form however - in most cases David's criticism is valid. One 'gotcha' with not using an actionform is when you are using multipart forms. Struts is nice enough to wrap multipart requests in a MultipartRequestWrapper with the POSTed parameters available *but* it populates this wrapper from the same method that populates the actionForm. No action form means no MultipartRequestWrapper population, which means request.getParameter will return null for all except those parameters appended to the url to which the form was submitted.

How Smart is DynaActionForm?
Hello, I have an ArrayList as a element of an DyanActionForm. The list contains elements of another bean that has properties as strings. I can populate the DynaActionForm in my action and have the JSP to display it . The question here is does DynaActionForm has the intelligent to reconstruct itself after the form is submited back to the server? I tried but the ArrayList always come back emtpy..

Subject: Re: Too many session scoped form beans!
That is just an example, I don't know what MAX value can be used for the
datas you want the user to submit.
Another solution would be to put form-bean into session scope and add a
to-be-removed mecanism :
When an action puts some form-bean on session scope for editing, it can
set a to-be-removed string in session scope
with the form-bean name.
Every action of the application has to do is job, and look for this
to-be-removed. If it exists, remove the associated
objet from session.
This way :
- Your action sets the form-bean for editing, with an intialized ArrayList
as item property.
- Jsp generates HTML text fields for items.
- If user follows the correct application behaviour, your edit-action gets
its form-bean from session and can remove it
itself.
- If user clicks on menu or use a bookmark, form-bean will be removed by
any other action.
Nico.
Of course, your newest solution is better, but it still does not feel
right
regarding the MAX_INDEX allowed ;-)

Subject: Re: Too many session scoped form beans!
Reading my own post I realize this code will throw an
IndexOutOfBoundsException
You need to put 'empty' datas on the List as needed :
protected List item;
public void setItem(int index, Object obj) {
if (this.item == null) {
this.item = new ArrayList(index);
}
for (int i = this.item.size(); i index; i++) {
this.item.add();
}
this.item.add(index, obj);
}
Nico.
I think you can use something like this in a request scoped
form-bean :
protected List item;
public void setItem(int index, Object obj) {
if (this.item == null) {
this.item = new ArrayList(index);
} else {
this.item.ensureCapacity(index);
}
this.item.add(index, obj);
}
This way, when form-bean population occurs, you will get a new
Collection when needed.
Nico.
I'd like to know if it's possible to avoid using to many
session
scoped
form beans.
I have a bean that contains a collection and I use
nested:iterate
to
display entry fields on my html:form. When the form is
submitted,
I
get
an error in BeanUtils.populate(), because the new bean (when
the
bean
is
request scoped) contains an empty collection and populate()
tries
to
set
the properties of the elements that existed on the bean of the
previous
request.
If I change the bean to session scope, everything works fine
(because
now the bean is the same for both requests), but I think it's
kind
of
messy to have lots of session scoped beans.
I'd appreciate to have any comments on this subject.
Thanks

I see how struts-el would allow me to reference ${foo} values within the

Subject: Setting externally JNDI properties
Hi,
At present my application is 'talking' with Jboss via specific properties
set a compile time. I would like to move those properties in a
jndi.properties file (which I would put under WEB-INF/classes). How could
I
retrieve jndi.properties without specifying the exact location (which
could
vary from user by user), i.e. dynamically? I tried with the following:
getServlet().getServletContext().getResource(jndi.properties); but the
return is null.
I also tried
getServlet().getServletContext().getResource(/jndi.properties) but the
return was the same.
I also tried to put jndi.properties in the jar file containing the
application's classes but nothing.
Any idea?
Thanks,
Marco

Re: application.getRealPath(/) from ActionForm???
My guess about the null control serverlet, is because struts may not init
the form's control servlet after the form constructor completes.
If you can take a look at my answer to Setting external JNDI properties,
you can put your file in classpath and load it.
BTW, you might have a performance problem loading the file for every
constructor of your action object. You might want to load your file at
startup and access it thru a singleton.
Good luck.

Subject: Re: example of PlugIn for java.sql.Date Converter registration
Hi all,
as a follow-up to my question, wanted to thank Dan Tran for his help
and also Rick Reumann for his.
I was trying to add a PlugIn in the struts-config.xml file to augment
the functionality of the BeanUtils.copyProperties function to handle
java.util.Date going from a form to a model bean.
If this was obvious to others, please excuse the post, but it sure
wasn't obvious to me. I ended up reviewing the sources for the
validator and tiles plugins to get this to work.
Here's a snippet from my struts-config.xml file; in addition to loading
the custom converters, I wanted to be able to supply a value to be
used by the SimpleDateFormat, hence my dateFormat property below.
!-- A PlugIn to extend BeanUtils.copyProperties to handle
java.sql.Date --
plug-in className=torch.beans.ConvertUtils.ConverterPlugIn
set-property property=dateFormat value=-MM-dd/
/plug-in
And here's (below) the init() method I ended up with as a part of
implementing
the PlugIn interface. The basics came from Dan, and finding the
proper PlugIn to retrieve my dateFormat property was gleaned
from the sources.
Well, it works, but as to whether there is a cleaner/shorter way to
do this, I don't know, but would be glad to hear it.
regards,
-jeff
public final class ConverterPlugIn implements
org.apache.struts.action.PlugIn {
/**
* init - implements the PlugIn interface
*/
public void init(ActionServlet servlet, ModuleConfig config)
throws ServletException {
PlugInConfig[] plugs = config.findPlugInConfigs();
boolean found = false;
int i = 0;
while (i plugs.length !found) {
if
(this.getClass().getName().equals(plugs[i].getClassName()))
found = true;
else
i++;
}
if (found) {
Object fmt = plugs[i].getProperties().get(dateFormat);
if (fmt != null)
setDateFormat(fmt.toString());
}
ConvertUtils.register(new DateConverter(),Date.class);
ConvertUtils.register(new StringConverter(), String.class);
}
public static void setDateFormat(String fmt) {
fmt_ = fmt;
}
I had a default format, in case there wasn't one in the config file,
and in the DateConverter, I retrieved the date format...

1. Does anyone have an example of this they could offer up? i think

2. Do you really have to do this to get a java.sql.Date from a model

Re: application.getRealPath(/) from ActionForm???
Is your XML file static? If it does, you cam place the xml file in your
class path and use my other posted solution to have access to its
InputStream.
If you dont like to place it in classpath, you can create a Singleton
wrapper around your XML and load it up during application startup, via
Struts plugin or a servlet.

Subject: It's late and I'm feeling stupid
I have some data in an XML file.
I read it in from JSP using x:set (the JSTL X tags)
I then transfered it to a variable like so:
c:set var=somevarname
x:out ... /
/c:set
I can now dump it out happily using c:out
It turns out that this particular value (an integer) is useful in a
subsequent JSP page (if my user elects to go there by clicking the
appropriate link). So I want to pass it as a parameter when I link to that
next page.
Aha! the html:link allows me to add parameter information. But it
appears
that such info must be in a bean.
So I created a bean:
jsp:useBean id=foo class=java.lang.String/
But for all my efforts, I can't figure out how to get the somevarname
value into foo
I tried:
jsp:useBean id=foo class=java.lang.Stringc:out
value=${somevarname}//jsp:useBean
but that isn't working. (Subsequent attempts to bean:write name=foo/
come up blank.)
I just know when I wake up tomorrow, the answer is going to be obvious and
I'm going to feel stupid for asking. But one of the advantages of working
late without much sleep is that we don't care how we're going to feel
about
it in the morning.
Any suggestions?

Is your XML file static? If it does, you cam place the xml file in your

If you dont like to place it in classpath, you can create a Singleton
wrapper around your XML and load it up during application startup, via
Struts plugin or a servlet.

My guess about the null control serverlet, is because struts may not
init
the form's control servlet after the form constructor completes.
If you can take a look at my answer to Setting external JNDI
properties,
you can put your file in classpath and load it.
BTW, you might have a performance problem loading the file for every
constructor of your action object. You might want to load your file at
startup and access it thru a singleton.

If you deploy your app as a WAR file, then it is the correct result

there is no real directory to return
But you can use this code

where pathName is the context path to your file in the WAR archive.

Subject: Re: Too many session scoped form beans!
Reading my own post I realize this code will throw an
IndexOutOfBoundsException
You need to put 'empty' datas on the List as needed :
protected List item;
public void setItem(int index, Object obj) {
if (this.item == null) {
this.item = new ArrayList(index);
}
for (int i = this.item.size(); i index; i++) {
this.item.add();
}
this.item.add(index, obj);
}
Nico.
I think you can use something like this in a request scoped form-bean :
protected List item;
public void setItem(int index, Object obj) {
if (this.item == null) {
this.item = new ArrayList(index);
} else {
this.item.ensureCapacity(index);
}
this.item.add(index, obj);
}
This way, when form-bean population occurs, you will get a new
Collection when needed.
Nico.
I'd like to know if it's possible to avoid using to many session
scoped
form beans.
I have a bean that contains a collection and I use nested:iterate to
display entry fields on my html:form. When the form is submitted, I
get
an error in BeanUtils.populate(), because the new bean (when the bean
is
request scoped) contains an empty collection and populate() tries to
set
the properties of the elements that existed on the bean of the
previous
request.
If I change the bean to session scope, everything works fine (because
now the bean is the same for both requests), but I think it's kind of
messy to have lots of session scoped beans.
I'd appreciate to have any comments on this subject.
Thanks

Subject: Scope and Action objects (struts 1.1)
Hi there all,
I looked through the numerous queries in the archives
but couldnt find anything that answered my question.
If I have an action class, with a class member count
eg
public class QueryAction extends Action {
private int count = 0;
etc...
}
and in the execute() function I increment count by 1;
in my struts-config.xml
action path=/query
parameter=/WEB-INF/jsp/myform.jsp
type=web.QueryAction
scope=request
validate=false
name=queryForm
forward name=success path=/WEB-INF/jsp/myform.jsp/
forward name=failure path=/WEB-INF/jsp/myform.jsp/
/action
On requests to http://localhost:8080/query, on printing
out count in the execute() function in the Action,
I get the value 0 and 1, 2, 3 etc.. on subsequent request.
I thought by having scope=request the value of
count would be 0?
Is this right?
Would there be some other source code location where one
needs specify the scope?
My jsp form header looks like this
html:form action=query
etc..
/html:form
I noticed the scope attribute had been deprecated in the API.
Thanks in advance,
Chai

The flow is this way: 1. Url: http://localhost:8080/mydispatchaction.do?method=view ;here the information is pulled from the database and put to the actionformbean using its setter methods. 2. This mydispatchaction.do forwards to the jsp. There the information from the database is presented and can be changed and submitted again to the mydispatchaction.do?method=save This all works as expected. Unfortunatly as soon as I switch on the validate switch in the struts config (1.1x) the information that was written to the actionformbean seems to get lost and the jsp presents empty html:text fields. It seems like using the validate=true switch makes the actionformbean to be instantiated again. I can see the reset method is called between the setting of the formbean parameters and the viewing of the jsp because all parameters get the values set in the reset method if set there when using validate=true. All former settings get lost then of course. I do not understand why this is the case. How should the validate switch be used then? Or do I have to write the information that I want to present in a jsp using a actionform always into the session? I thought it should be possible to write it to the actionform inside of the dispatchaction if it is possible to read it from the actionform in the dispatchaction. Can anybody explain to me the best practice is in this case? How does the lifecycle look like of an actionform (for request scope settings in the struts config)?

Is this something that is reasonable to do in the action, or should I create another action path /EditUserAccount?user=username and filter that to only admins and then forward to the /EditAccount once the proper credientials have been established, hence relieving the action behind /EditAccount from looking at any roles?

Re: Validation - Require One of Multiple Fields
http://jakarta.apache.org/struts/userGuide/dev_validator.html may help. Look for twofield example. -D - Original Message - From: Joey Ebright [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, March 20, 2003 10:54 PM Subject: Validation - Require One of Multiple Fields Hello, I am looking for a way to validate that the user filled in at least one field of a possible many fields. These fields represent search criteria to use for constructing an SQL query to a database and I want to ensure the user gives me at least one item to search on... I looked at the requiredif validator but it is only server-side and I want both client side and server side validation. If I just wanted server side I could have written the validation code in my ActionForm myself... I did come up with some rudimentary JavaScript to do this but am lost at how to do this in the same manner in a generic fashion on the server side. The elegant approach of the validator framework on the client side is that it passes an array of fields that are to be validated and the validate method is only called once. This allowed me in my JavaScript to just see if the addition of all the fields put together equaled an empty string. On the server side, the framework differs in its approach to validation of fields and each field to be validated calls the validating method once. Hence without reworking the validator framework, the same approach cannot be used - unless of course I am mistaken. Anyone else got some ideas out there???

action attribute value with value ${loginUserForm.action == 'delete'}:

Then I replace ${loginUserForm.action == 'delete'} for
${loginUserForm[action ]== 'delete'} since
my form is a DynaForm
however, I dont think ${loginUserForm[action] contains the intended value.
am I using the correct syntax?

it just like any other bean:

Subject: Accessing DynaActionForm fields within custom tag
I have a form where the submit button is supposed to say add login or
update login depending on if the user in question (based on field
fkMember) already exists in the login database. I have tags called
HasLogin
and HasNoLogin that take an integer parameter, and return whether or not
the

I am using a DynaActionForm to populate the rest of the fields. The
DynaActionForm is a session scoped bean called loginForm -- the

!-- rest of page below --
The syntax above offends my sensibilities. First, I ought to be able to
refer to the bean in question without using a jsp:useBean I think; it's
obviously available to the rest of the form, if the form works (and it

For example, ActionForm contains a property, today which will contain a string value -- say 20030312. From this value, I need to generate 5 additional business days to be provided in the options pick list. In order to generate additional values, I need to assign a reference to a variable.
