Struts Upload File Question

[VEDRE, RANAPRATAP REDDY]

 I am trying to implement a feature that allows users to upload multiple
files at the same time(Similar to Yahoo Mail attachments).

user should be able to select upto a maximun of 5 files on a single page and
all the files are saved to the database on submitting the form.

I am using FormFile in struts upload package for the purpose and storing the
FormFile objects in a vector.  what would be the best way to handle this?

Also,how can i show image and text(html markup) on the same page.
if i set the content type for the response to image/gif and  return null for
ActionForward, them image shows up but i cannot display text on the page if
i write it to the output stream. 

dint find the solution to this in the mailing list archive.

any comments/ideas are welcome.

Active users in a struts web application.

[VEDRE, RANAPRATAP REDDY]

Not a struts specific question, but i know where the experts are...

I am tring to show the users currently logged into a web application, so
that anybody who logs in can see who else is logged in.

This functionality is similar to a standard chat program.

i am using ServletContextListener and HttpSessionAttributeListener classes
in the server API.

Struts 1.1b2, so i can use Plugins if needed.

Any help/ideas about tracking users currently logged into a web application
are most welcome.

Subject: How to Access an Application Scope object in a Struts Action Clas s

I'm relatively new to Struts, and I am working in Struts 1.02 (since we
are
not comfortable using a beta version of struts on a new project), and I
am
stuck on a simple problem.  If I create a Hashtable bean object called
monitor, with application scope, in my Welcome page using



how do I access this application scope object in all of my Struts action
classes?  I've tried using  Hashtable monitor =
(Hashtable)session.getAttribute(Constants.MONITOR_KEY);
if (monitor != null) {
-do something---
}
and I get a null pointer error, as seen from my error log below:

01/14 18:30:47 error 
java.lang.NullPointerException
at com.NYTC.struts.LogonAction.perform(LogonAction.java:144)

where line 144 is the if (monitor != null) statement.

My objective in using the monitor bean is to keep track of every user
who
logs in, and if they still have an active session, recover any data and
then
invalidate the old session, and create a new session for them.  We were
doing this in our previous web apps, but we were using a Model 1
approach,
so I am having some trouble converting this concept to a Model 2
approach.
In our Model 1 apps, we just used the monitor to keep track of user's
sessions, and invalidate any active session still on server as follows:

if (monitor.containsKey(user)){
HttpSession oldSession = (HttpSession)monitor.get(user);
System.out.println("User already has an active session in memory
"+
oldSession.getId());
---retrieve old data in between here and then invalidate old
session--
oldSession.invalidate();
System.out.println("Got rid of the old session");
} else {
System.out.println("No old session was found");
}   
monitor.put(user, session);

How do I accomplish this using a Model 2 approach??

Thanks in advance for any insight/advice

Subject: Struts--- Validator plugin HELP NEEDED!!

Hello to all struts users.

I am facing somewhat unusual problem.The cuurent project is being built
on
struts 1.1
All the validations were earlier done is ACTIONFORMS.for good
application
architecture we have decided to go for StrutsValidator/ Validator plugin
which will take care of all the validations.

All common validations are being done using the validation.xml and
validator-rules.xml.
(minlength, maxlength, email, required)
for customised validation we have made validation-custom.xml and
validator-custom-rules.xml.
(field comparison etc)

I have removed the Validate() from the ActionForm and set
validation=false
in the action mapping of struts-config.xml(This was done later as we
thought
setting to true invoked the validate().So we set it to validate=false,
inorder to invloke the plugin).When the application starts-up the
digestor
reads the xml files and hold the validation in struts memory.All the
error
messages are given in the resource file.But we don't understand the
validation is not occuring.We believe struts is not able invoke and
passe it
to the plugin.

Below is an extract from the struts-config.xml.The Tiles plugin works
just
fine ..but Validator plugin does not work at all.















Any ideas from your guys...?

Help is appreciated.

thanx
Vijay

RE: Passing data to presentation objects

[VEDRE, RANAPRATAP REDDY]

 
 This is how i use value objects.

 I have a property in my form called view.  It is user written class and
contains all the information that needs to be available in the jsp.
This view object has to be initialized in ur action class before forwarding
to the jsp.

I find this especially useful when there is a lot of information to be
obtained from a database, to be displayed in a jsp. ActionForm contains only
the fields that the user enters/submits in the html form/page and all other
data is embedded in the view class.

lets say u have have a couple of vectors(Containers) to be initialised from
the database for rendering select boxes.

You can store the vectors int the form, or add each vector seperately to the
request object.

By using a view class which contains two vectors as member variables.
you have to create an instance of the view class and call the set methods to
initialize the two vectors in the instance and then set the ActionsForm
"view" attribute with this instance.
Then in ur jsp,get the view instance from the form and the vectors from it
using  tag or something similar.

It is  bit more work than adding the vector objects directly to the request.
but it has the advantage in that u can easily see which view objects are
used for an Action or JSP just by looking at the form declarations in
struts-config.xml(if u are using dynamic forms)

Subject: Passing data to presentation objects

Hi,

I have been reading a lot of material on Struts, but I could not get
answer to my question.

What is the recommended strategy (or a design pattern) to pass data to
the view objects (JSPs in my case)?

One reply I got is to use the form-beans associated with the actions to
pass data to the JSPs. I found some situations when this did not work
well (for example, I faced this problem when I am trying to use the same
form-bean for populating data as well as editing/submitting a form).

What are "value objects" and how are they useful in passing data? Can
someone refer me to a good resource on knowing more about this? Any
examples would be highly useful.

Also, is there any sample application I can download and which can be
used as sort of a reference for common tasks required for struts
programming?

Thanks,
Suresh

RE: Difficulties with form bean validate() for pre-populated form beans

hi micheal, 
 this is a very common problem. 

 u can have validation="false" in ur action mapping in struts-config.xml 
and call the form validation method in ur action class. 

formInstance.validate(request, errors); 

by having validation="false" struts does not call the validation method in
ur form. 

i stringly suggest using validation framework. since u are using 1.1b u can
even use DynaValidatorForm. 

 by using validation framework u dont have to write the validation method 
for ur form. u just have to specify the validation in validation.xml file.

Subject: Difficulties with form bean validate() for pre-populated form beans

Hi,

I'm using Struts 1.1b and one part of my webapp is a registration page
for new users.
I have to say that this thing works already somehow, but not really as
I'd like to have it.

Currently I'm not using the validate() method in my form bean and I'm
doing all form validation in the action class.

This I do for one reason: I need to pre-populate my form bean!

So I don't link from my webpage to "newaccount.jsp" but instead I link
to "newaccount.do" which is partly pre-populating the form bean for my
view newaccount.jsp because I need some data from my DB to dynamically
generate a pull down menu for my registration page.

So my newaccount.do is loaded, populates the form bean from DB,
validates the form data (if there is any at this moment) and forwards to
newaccount.jsp. 
The view now generates the html form and the pull down menu according to
the bean data from DB and waits for the user to submit the data back to
newaccount.do.

This time newaccount.do finds values in the form bean, validates it and
in case of errors submits back to the view displaying the ActionErrors
(still being able to use the db data for the pull down menu) or if
nothing went wrong it generates a new user entry and continues to do
something else.


So far that works, but I wonder if I shouldn't use the validate() method
of the form bean for simple validation checks. E.g. the user must enter
an not-empty email address or whatever.

Here comes my problem after I copied the validation work from the
action's execute() to the form bean's validate(). 

Because I need to pre-populate the form before displaying the view
whenever the validate() method finds an error it returns to the "input"
page. 
But in order to generate the input view, I would need to pre-populate
the form. Unfortunately in case of errors the execute() method that
would usually pre-populate my bean is now never called...

If I set "input" in struts-config.xml to "newaccount.do" I only get an
endless loop, after submitting wrong form data.
But if I choose "newaccount.jsp" I will get jsp errors because the html
form can't be build because of the missing form data.

So what do else?

The only examples that I found in my books about Struts where validate()
is used are too simple and just consider the case that the input form
doesn't need any pre-populated form data and would just sit and wait for
data. 

So I hope that anyone could give me a hint how to handle this problem
and could tell me how to use validate() + pre-populated forms or maybe
there are other more reasonable ways to tackle this issue.

Thanks
Michael

you can create a collection for the rights and store it in application

then use the  tag and  tag to render the admin

you can use ten  tags for login fields or look into the

RE: How do I do this, input field retains value

[VEDRE, RANAPRATAP REDDY]

 you can remove the form from request or session based on the scope in which
u stored the form after database is updated succesfully.
 
 
// Remove the obsolete form bean
if (mapping.getAttribute() != null) {
if ("request".equals(mapping.getScope()))
request.removeAttribute(mapping.getAttribute());
else
session.removeAttribute(mapping.getAttribute());
}

this will make struts create a new form.

RE: 2 submit buttons with different action

[VEDRE, RANAPRATAP REDDY]

you can configure your action mapping with validation="false" and do the
validation in ur action class by calling the validation
method of your form(DynaValidatorForm).

struts does not call the validation method, as validation="false"
you can check in ur action class which button was pressed and call the
validate method only when submit is pressed.
you still dont have to write ur validate method as long as u have the form
in the validation.xml.

to check which button was pressed you can use the following in ur jsp


Submit


Back


and in ur action class 

  String buttonPressed = form.getAction();
  if(buttonPressed.equals("Submit"))
form.validate(request.errors);

  if(!errors.empty) 
   {
return mapping.getInputForward();
   }

  
 note that action should be a property in ur form. as u are using
dynavalidator form it should be present in ur form declaration in ur
struts-config.xml

In this page :
http://jakarta.apache.org/struts/userGuide/dev_validator.html

the doc says :

The most fundamental change is the ability to conditionally require
validator fields based on the value of other fields. It allows you to define
logic like "only validate this field if field X is non- null and field Y
equals "male".

I think it is possible to do what you want with the validator but don't know
how.

1. make sure u are not creating a new instance of the form bean in the
second action and you have name attribute for both the action mappings(they
should be same, since u are using same form in both actions).

2. if you are going from the first action to the second action directly(ie.,
first action is not forwarding to a view/jsp),u dont even have to keep the

Hi,

I defined 2 actions in session scope referring the same form. The first
action sets some properties in the form and then forwards the request to the
second action. The second action sets some more properties and then forwards
to a JSP page which contains the html form. The problem is only the data set
by the last action remains... This makes me think the form-bean is not
shared between actions. I understand this can be desired behaviour. Any

both 1.32 and 1.30.

Yes, trying that now, no luck.  I guess it sounds like a local issue,
since you probably would have recognized if I had been doing something
silly :)

I'll keep looking, it just doesn't seem to be doing an instanceof on the
dest bean anywhere in the call chain to see if it should treat the
DynaBean differently.

RE: PropertyUtils.copyProperties() usage in 1.1-b2

[VEDRE, RANAPRATAP REDDY]

 try getting the latest version of commons-beanutils.jar from commons
project version(1.5), if u dont want to upgrade to nightly build of struts,
but use struts 1.1b2.

  In  version 1.5 of commons package, PropertyUtils works in both
directions. release notes for version 1.5 montions about this fix.

You may also want to look at BeanUtils.copyProperties(bean, bean)

Subject: PropertyUtils.copyProperties() usage in 1.1-b2


Hi all, happy friday (again... :)

I'm trying to figure out what I am doing wrong with
PropertyUtils.copyProperties().  From within my Action, I have:

User user = ;
DynaActionForm regForm = (DynaActionForm) form;
PropertyUtils.copyProperties(regForm, user);

When I look at what copyProperties is doing, it's getting a
PropertyDescriptor array from getPropertyDescriptors() with the user
bean correctly, then it iteratively tries to see if the regForm has any
of the properties found in the user bean.  But calling
getPropertyDescriptor(regForm, ) seems to be comparing the
(correct) field names from the bean against the *structure* of the
DynaActionForm component (i.e. the multipartRequestHandler, dynaClass,
servlet, etc), instead of the DynaFields that I set up in my
.

I don't think nested properties are the answer, and copyProperties() is
supposed to work with DynaBean in the source, destination, both or
neither.  

Any ideas?  The code seems to work fine when the source and destination
are reversed.  I'm using 1.1-b2.

Thanks a bunch,

Brian

Greetings,

I love struts, but I'm currently getting my ass kicked... please help. :)

I'm trying to use Message Resources in my web application, but I can't get
struts to find the resources.properties file.  This is how I'm trying to
structure my web-application:

Note: "aaw" is the top-level directory.

aaw/
aaw/
aaw/WEB-INF/web.xml
aaw/WEB-INF/struts-config.xml
aaw/WEB-INF/resources.properties// note this line.
aaw/WEB-INF/tlds
aaw/WEB-INF/tlds/
aaw/WEB-INF/lib
aaw/WEB-INF/lib/
aaw/WEB-INF/classes
aaw/WEB-INF/classes/

Now, what do I set the  tag/parameter to in my
struts-config.xml so that the resources.properties file above will be
found???

All of the examples I'm finding have that file in some strange (to me)
location, like "src/..." or "classes/...".  Can't I just have in at the
top-level of the WEB-INF directory???

Thanks in advance!

Thanks for the help, it was a type mismatch in another section of the

I have a new question, is there an easy way to iterate over a collection
and print output in, for instance, groups of 5? In other words, I have a
list of products in a catalog and I want to display a table on a page
with 5 items per row and as many rows as needed. Is there a method to do

 I"m not a JDeveloper user, but as I recall it is (or at least was)
an IDE based on JBuilder and licensed by Borland/Inprise to
Oracle.  If that is still the case then maybe you need to follow
the same steps to integrated Struts with JDeveloper as you 
would for JBuilder.  That means installing the open tool to
add the *.tld files to the war you build and remove struts.jar
from the Tomcat classpath.  Try looking at:

and ignore the stuff specific to WebLogic.

If you look at the Jetspeed implementation carefully, It does provide
content entitlements based on role and user group. Basically, You can
customize and personalize the content presented at user community level. If
you are looking for deeper personalization based on Profile and event based,
You might want to consider developing some custom tags/classes that will be

 Interested in getting links to sites providing customization build using
struts.

- Thanks

RE: in web.xml and 404 HTTP error

[VEDRE, RANAPRATAP REDDY]

  when i used "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd";
it dint work so i checked out this url and it gives a mesage saying the url
has changed and servlet 2.3 should use
 "http://java.sun.com/dtds/web-app_2_3.dtd"; i.e., without the j2ee.

 no clue what is the problem. 

still i get an error when i start my tomcat witht the new 2.3 dtd and error
page still does not work.

please let me know if you know about this.


 I am not sure if there is something to with struts or tomcat or servlet api
version on my pc.

stack trace when i start tomcat:
=

Make sure you use "web-app_2_3.dtd" at the top. I'm afraid that if you
use
"web-app_2_2.dtd" it will not work.

in web.xml and 404 HTTP error

[VEDRE, RANAPRATAP REDDY]

 I have tried to use  directive in web.xml for 404 http error
and direct to a custom error page. But could not get it to work.

 i know for tomcat 4 the error-page directive has to before the teg lib
descriptors. but still does not work.

 Can anybody please give the syntax and placement in web.xml for catching
404 error.

 -Thanks.

Using more then one properties(resource) file for a language.

[VEDRE, RANAPRATAP REDDY]

I guess we need to have a properties file for each language that we support
for a web app.

If there are a lot of pages in the application its gets messy to have all
the message texts  in one properties file and difficult to maintain(modify).


 Can we organize the resource files for a web application into groups so
that each language can have more than one resource file.

For example :   
   For english
   english.resource1
   english.resource2

   For japanese
   japanese.resource1
   japanese.resource2

 I could not find anything like this in documentaion. Did anybody use
something like this? 

-Thanks
