Re: How populate a form

[Rahul Mohan]

Hi Daniel...

what i had done in my application was create the childform's actionform
instance in the action class...run the query...populate the bean and then
put it as a request attribute to prevent the RequestProcessor from creating
a new form bean object.

Hope this will work for ur app too...

regards,
rahul

Using the ActionForm in the JSP

[Rahul Mohan]

Hi everyone,

I need to access the ActionForm properties inside the JSP code for the same 
window. Is there any way to do this? 

Regarding this I have some doubts about the life cycle of ActionForms

1. When exactly is the ActionForm object instantiated? Is the ActionForm object 
instantiated only on submit of the corresponding form? or is it instantiated while 
rendering the page?

2. Also I need to set some properties to default values at instantiation of the 
ActionForm. Can I simply override the ActionForm constructor in my action-form? That 
doesnt look like a good strategy since the constructor implementation in the 
ActionForm does not seem to be made for overriding as it has some code in it ( its 
simply servlet = null ) so is it wise to simply override it? it seems a bit over 
smart idea!!! :) 

Please help me out..

thank you,
rahul

Re: tag inside tag

[Rahul Mohan]

Hi Max,

Thanks for the reply...

I have found a work around for the problem...but it looks wierd!!

These are the steps I performed:

1. I am setting the styleVar as follows:



some JSTL conditional stmts



2. Then I retrieve the value using the following scriptlet:

 <% String str = pageContext.findAttribute("styleVar").toString(); %>

3. Now I can use the value of str inside my  tag as follows:

 

The wierd part is that if I put

style="<%=pageContext.findAttribute("styleVar").toString()%>"

inside the  tag it wont work!!!

Can anybody tell me why it is so?? I am stumped!

thank you all...

validate method

[Khandelwal, Rahul]

Hi All,

For some reason, I have to do some form field validation in my Action class.
And, if the validation fails, I have to return the control to the
same(input) page to display the error msg (using ). I have
previously done it in the validate method in the Form bean, but don't know
how to put the validation in the Action class.

Any help will be much appreciated.

Thanks,
Rahul

This implies that they are currently using an online spreadsheet program.
Are they, or do they want you to build them one?  I would hand them a CD

Re: DTO vs. JVT

[Rahul]

Hi Dan,
Have a look at the following article.

http://javaoneonline.mentorware.net/servlet/mware.servlets.StudentServlet?mt=1055755038320&mwaction=generic&subsysid=2000&file=dan_malks

IMHO , the Transfer Objects "live" and "operate" in Business tier and View
Helper objects in Presentation Tier. My understanding is that they both are
value objects, unless someone can elaborate on any differences between the
two(which would be great !).

and I stick to using pattern names from the ones listed in Design Patterns
and Core J2EE patterns catalogue .

Design Patterns

[Rahul]

Guys, 

I came across this coool article on core Design Patterns in J2EE. Check it out ! 

http://javaoneonline.mentorware.net/servlet/mware.servlets.StudentServlet?mt=1055755038320&mwaction=generic&subsysid=2000&file=dan_malks


Also, It would be interesting to know what patterns we are using in Struts. Pointers 
to classes that consitute a pattern would be great !!
And i think it would be a good idea to have this thread as a one stop guide to 
patterns in struts ! I can assort the responses and post them up (somewhere?) for 
ready reference. 

cheers :-)

UML diagrams in Struts source

[Rahul]

Greetings All, 

First of all, I take this opportunity to congratulate Ted, Cedric, George and David 
for an amazing job with their book "Struts in Action" (I got my copy couple of days 
ago). So much so that I am inquisitive and 've set my copy aside today and downloaded 
the RC2 src and having a look at 'what lies beneath' !! 

As for the source, it's well-documented, explained and with UML diagrams. ah ! that 
reminds me .. I would like to know if these UML diagrams are being generated by an 
open source tool. May be I could use something like that to get some neat UML diagrams 
for other few java project trees sitting on my PC and whose number of source files is 
dreary enuff to make me dizzzy. 

also, it might be a good idea to invite some suggestions on this list on what 
different strategies people adopt on  "reading" and understanding a piece of software 
? 

Suggestions please ...! 

Cheers,

Re: Does a degree matter?

[Rahul]

Hello Brandon,
I agree with Jeff and Craig. I think its the "can do" attitude that should
matter, and not just the "has done" facts :p

I never touched or learned programming until I graduated  in Commerce.
Simultaneously pursued my hobby in Japanese and then landed in job as a
language specialist... with a .guess what ..a software
company. That was when I was bitten by the programming bug :p , and have
never looked back since then. I have done a certificate course and quiet a
few certifications and had an oppurtunity to work for some good companies
over the last 6 years.

No doubt , its not a smooth sail for many of us in current times. there
are employers for whom degrees are a bare minimum to even look at a resume.
But I think, personally for me it finally boils down to pursuing what you
want to. Though nothing measures up to hand-on experience but then that's
not undermining the hard work many of us put in when earning degrees. I
think the 2 descions pointed out in Jeff's email are crucial.

cheers :)

Rahul

Using database tables for resource bundles

[Rahul]

Hi,
(B
(BWe are developing a multilingual system using struts 1.1 and j2ee 1.3.
(B
(BI need to know whether we can use backend database tables for providing all the 
(Bmessages i.e. whether the messages can be provided by a set of java class rather than 
(Brelying on resource files residing on the server.
(B
(BThe reason why we want to use database is that when the application is live/running in 
(Bproduction mode, we may not have access to physical files lying on the server m/c 
(Bwhereas the information stored in the tables can be accessed/updated from remote sql 
(Bclients. Another advantage of using database could be that if needed we can provide a 
(Bgui/maintenance for the admins to modify the messages as and when required. In this 
(Bcase, we may also choose to decide about some strategies for sychronizing of the

RE: Question regarding sessions

[Rahul Kumar Saxena]

Hi Michael,

I hope that I have understood your question correctly. Let me reframe
the situation :

You have a tree structure which you want to display in unexploded form.
User will select any of the nodes which can appear at any level of tree.
Now after putting something in the basket, you want to take him back to
the tree with same state as it was before adding to basket i.e. in the
exploded form.

If this is the case then you can have a list of list to make tree
structure and in order to display the tree again, you just store the
root list in the session. To display the earlier state of tree, what you
can do is to have a java bean stored at each node of tree with a
property  to identify if it is exploded. Now based on this property you
can rebuild the exploded tree. One catch in this approach is that if you
want to dynamically add or delete some nodes from tree then you have to
explicitly add or remove nodes from the root list.

I hope this solves your problem.

Multiple submits

[Rahul Kumar Saxena]

Hi All,

I am facing a problem related to multiple sumbits. 

We are developing a wizard kind of application with frames. For this we
use business object(BO), which are nothing but a replica of forms, used
in JSPs. We store this BO in session and keep on updating it with the
values present in various forms. At the end, we pass this BO to EJB
layer to process the DB operations after which we display success or
failure page depending on the success of DB operation. To do final
submit we display OK and Cancel button in all the JSPs along with Next
button. After successful DB operation we remove BO from session (to make
session light).This is where our problem starts.

If user clicks final OK and first thread completes the DB operation;
just before the success page loading user clicks Next button. Then
second thread tries to look into BO which was stored in session, for
some values. Since first thread has already removed the BO from session,
second thread throws NullPointerException. Not only this if user clicks
OK button, more than once then we land up either with same record
entered in DB more than once or again NullPointerException.

I went through various threads and almost every where people talk about
using Tokens. If I use tokens then what shall I do if token is invalid?
I can't show him a page saying that your first request is under process,
'coz at the end I have to forward the request to success page.

TIA,

RE: AW: html:text initial value

[Rahul Kumar Saxena]

Satish is quite right, you just call
setTextBoxPropertyName("00.00."); method in the action class which
forwards to your JSP. This will take care of displaying the default
value.So you need not set 00.00. in the value attribute of text
tag.Becuase this always sets the value to 00.00. irrespective to the
value present in the form object. 
For the case of errors, you need not worry at all, Struts will populate
your form properly. 

 


is same as



Only difference is that in the first, you are exposing 00.00. value
as geburtsdatum variable.

Inside JobObjects bean, add one attribute for checking if this job is
checked, say selectedFlag (Not a good name). Set the value of
selectedFlag to true for all the JobObjects which you want to show as
selected.This you can do in the action class which forwards to this JSP.
While creating the checkboxes, first check if selectedFlag for that
JobObjects is true then display the checkbox as selected.This can be
done using logic:equal tag.

Subject: marking checkboxes checked from a List


I'm sure there is a good way to handle this in Struts but me being the
dumbass I thought I'd ask for help:

Picture a case where you display a list of "jobs" -
where next to each job name is a checkbox (Just using jobs for this
example). Each checkbox corresponding to the job will have a value that
is a String (jobAbbreviation). Displaying this list of jobs and the
value of the checkboxes isn't a problem ( populated from an ArrayList of
JobObjects ).

The problem is:

How do I mark the correct checkboxes based on an ArrayList of Strings
(jobAbbreivations)? In other words I have just a List of Strings and I
need to mark all the appropriate checkboxes that have the same values as
this List of abbreviations. ( I know an ugly way to do it using java in
the JSP page checking each value to see if it's in the List but there
must be a cleaner way ).

Thanks so much for any help.

RE: Question on implementation with frames

[Rahul Kumar Saxena]

Hi JiRong,

You can use single action class for all the three links and based on
link clikced you can forward the request to corresponding page. In order
to store the value accros the links, you have to store you form in
session. For that you can declare session scope in Struts-config. Apart
from that you may have to take care of removing the form from session
after save.
If different kind of mandatory validations are required for different
links then I would suggest you to use different action class with sngle
form object.

Subject: Question on implementation with frames
From: "Hu Ji Rong" <[EMAIL PROTECTED]>

Hi,

I have a web page with 3 frames, a menu on top with three links to
different pages. When the links are clicked, the destination page will
be displayed in the middle frame. The bottom frame have a list of
buttons like "save", "cancel".

===
(Top Frame)
link1link2link3
===
(Middle Frame)
content of link1/link2/link3
===
(Bottom Frame)
Save/Clear/Print
===

Content of link1,2,3 are all forms with input fields and all fields are
actually belong to the same object such as "Airport". The purpose of
this app is to collection all the data fields of "Airport" which will be
displayed in content of link1,2,3 into database.

The reqirement is: when the user enter some fields in either link1,2 or
3, these fields should be save in the memory(maybe an Airport object),
the user is allowed to navigate from link to link while these already
entered fields should display the entered data.

When "save" in the bottom frame is clicked, the program should check the
completion of mandatory field and save the object to db.

How can I implemented the action servlet? I am think about using one
single action class with parameters to know which link is clicked or
"save" is clicked, and use one single form bean to get all the fields.
Will that work?

Thanks for reading such a long message.

RE: (newbie) using JAR files vs. explicit package classes

[Rahul Kumar Saxena]

Hi Glen,

This convention is followed to identify the third party or external jars
from the ones, which you had developed for your application - project.
This gives clear picture of external resources being used in the
project. There is absolutely no probs in putting all files in a single
jar, as long as it is in classpath. Only thing is that it will be
difficult to identify what you have developed.

Hello,

I'm looking at how the example .WAR applications
supplied by Struts 1.1 Beta release are expanded by
Tomcat.  

Common/Shared packages, such as "struts.jar", "commons-digester.jar",
etc. are kept unexpanded in
the web-inf\lib directory.   However, classes specific
to the application were expanded into separate
directories:  e.g.,
\classes\org\apache\struts\webapp\example\memory\MemoryUser.class,
MemoryUserDatabase.class, etc.

I'm trying to understand the reasons behind this
deployment convention--What are the benefits of
splitting out application-specific projects/classes
into separate directories and .class files when
deploying?  (i.e., Can't they be more cleanly stored
together in a JAR file like struts.jar, etc. is?)  

Thanks,
Glen

String[] for html:select---Urgent

[Rahul Chaudhary]

The following error is being generated while using a String[] for 
.Looking forward to your help.

javax.servlet.ServletException: BeanUtils.populate
at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:774)
at 
org.apache.struts.action.ActionServlet.processPopulate(ActionServlet.java:2061)


There is this code in the jsp:

<% int i = 0;%>

<% String userSelect = "userSelect["+i+"]";%>

 
 
 
--Select Field --


 

<% i =i+1;%>


In the formBean the mutators are as follows:
String[] userSelect;

public String[] getUserSelect() {
return userSelect;
}
public void setUserSelect(String[] _userSelect) {
userSelect= _mapFieldSelect;
}
public void setUserSelect(int index,String _userSelect) {
userSelect[index] = _userSelect;
}
public String getUserSelect(int index) {
return userSelect[index];
}

In the reset() of the form bean there is this code:

  int userSelectLength = userSelect.length;

struts -- internationalization

[rahul sharma]

Hi,
I am working on a web application using struts
framework. I know Struts provides internationalization
of messages and labels using MessageResources. I have
a requirement that all the error messages (not the
fields labels on the form) should come from a table in
the database. I know how to do this using a
messageresource properties file. Is there any way I
can retrieve the error messages from a database table
and still be able to provide internationalization.
Please help.
