Re: Dynamic Value for logic equal

[Vikram Goyal]

Thanks David/Edgar,

I have actually done it in a scriptlet, but it is departing from the idea of
keeping JSP's scriptlet free. I am surprised that there is no generic way of
handling this in Struts. I always assumed that it would be till I actually
had to do it !!

The EL approach seems better but how was this tackled before Struts-EL came
into picture? I am guessing the scriptlet way?

Regards,
Vikram

Where should we change dispatch

[Mr Alireza Fattahi]

hi, 

we have a form that has more than one action. The
actions of the form 
could are changed depending on previous action.
Actually there is a state diagram
between actions. For example if A,B,C are actions
then:
A--> B --> C

Now where we can change the action ( dispatch
parameter)? 
There are two solutions:

1) change dispath in action form

  DynaActionForm dynaForm = (DynaActionForm) form; 
  dynaForm.set("dispatch","A");

2) put logic.equlas tags in jsp and change the dispath
hidden form 

 
   
 

Which one is better

There are many properties in an application that need to rendered

Re: Problem with multiple html(jsp) pages sharing one form (actionform)

[Derek Lin]

Didn't get this to work the way I want.  The problem is that I don't know
how to set the page property of the DynaValidatorForm without using my own
Action.

The best thing I can think of so far is to use my own ActionMapping to set
the page.  And in my Action class, I set the page property of my
DynaValidatorForm from my ActionMapping property.

This sort of work, but I don't like it:

1) in my validation.xml:

  
   
...
2) in my struts-config.xml:

  
  


3) I have a custom ActionMapping which sets the page property

4) In my Action class:
 public ActionForward execute(ActionMapping mapping,
   ActionForm form,
   HttpServletRequest request,
   HttpServletResponse response) throws Exception {
MyActionMapping fcMapping = (MyActionMapping)mapping;
DynaValidatorForm myForm = (DynaValidatorForm)form;
myForm.setPage(fcMapping.getPage());
...

Problems I've noticed:

1) Too much work
2) Javascript validation doesn't work on second page (works only on first
page)

I don't know struts inside and out.  I wish those of you who do can provide
an example application (just an multi-page form)  for this.

Anyway, just wanted to share what I have found out.

Re: Java WebStart as a Strut front end

[Toni Charlot]

I thank you for the correction.  You're absolutely correct.  No I can ask my
questions in a more clever way and perform searches as Eddie suggested.

I looked at the link provided, it wasn't very clear but I can see that it's
doable.

Some one ask why the need to go through the web-app and not interface with
the database and server directly?
answer:  I would like to keep the validation, database access, and other
business logic excecution in one place.  the Swing app will be a module
because of the need to access local i/o devices such as the printer, camera,
signature pad, and the like.

May be I could do that through JMS.

Thank you guys and gals.

Re: Making peace between Struts logic iterate and Ed Hill's display tag...

I don't understant why you can't use logic:iterate tag. 

Anyway, why don't you use a "for" instead of all those "if", something like 
this ?


<%!
// Convert a int to a 2 digit String
private String int2DString(int i) {
   String number = new Integer(i).toString();
   if ( i < 10) {
  number = "0" + number;
   }
}

private String propName(int i) {
   i++; // i was zero-based
   return "stuff" + int2DString(++i);
}

private String propTitle(int i) {
   i++; // i was zero-based
   return "Stuff " + int2DString(++i);
}
%>

Wouldn't this work.  Still ugly but if you use XML syntax might be
passable.

Since then, with Rick's help (and Rick deserves a lot of credit for
figuring out how to use this display tag library by the way), I have
managed to implement the display tag in my Struts based application and
it seems to work just fine.  The problem?  My code is ugly as sin!  It's
so bad, that after glancing over my shoulder the other day, one of my
best friends at work (Hi Russ!) has already warned me that it will
undoubtedly fail the upcoming code review.  He's got a point too - it is
Coyote Ugly Code!

The reason is that neither Rick nor I have figured out a way to make Ed
Hill's display tag live peacefully with Struts logic iterate tags.  As a
result, I have JSP code which looks something like the following :

<%
FooBarBean FooBarBean =
(FooBarBean)request.getAttribute(FooBarBean.LOOKUP_KEY);
%>


   Beautiful Looking
Spreadsheet in the Broswer Brought to you by Hideously Ugly Looking

<% if (FooBarBean.isExistingColumn(0)) { %>
   
<% } if (FooBarBean.isExistingColumn(1)) { %>
   
<% } if (FooBarBean.isExistingColumn(2)) { %>
   
   ...etc., etc...
<% } if (FooBarBean.isExistingColumn(29)) { %>
   
<% } %>



... and Java code to support this which is simply to hideous looking to
post in front of a family audience... (Russ happened to catch me
desparately trying to prettify the most hideous looking class of the
bunch!  There are some things which simply no combination of comments
can help :-).

So please, just shoot me already!  Either that, or help me with this
agonizing problem which is causing me to lose sleep (normally I sleep
late on Saturday mornings if I stay up late the night before).  Of
course, it doesn't help that in this case, I have variable columns which
may or may not appear (causing the need for the additional "if
(FooBarBean.isExistingColumn(x))" scriptlet code.  Even without that
problem though, it seems that I would still end up having to in line my
display columns with silly looking class properties like stuff00,
stuff01, stuff02, etc., all the way to stuff29 for each of my 30
possible data columns when I would normally write a much sexier loop
through an array (or even sexier - a collection) - all because Struts
logic:iterate tags don't seem to want to play with the display:column
tags!

We have tried asking Ed Hill about this problem, but Ed has been pretty
busy lately (either that, or it is entirely possible that our emails to
him at his email address posted on his web site are being lost in
mountains of junk mail - which is the problem I am faced with on one of
my more well known web site email accounts - making useful
correspondence with me almost impossible to that email address).  Ed,
are you still with us?

Anyway, as my code review approaches, I thought I'd try one last time to
spare this otherwise extremely powerful display tag library from the
hungry jaws of the code reviewers at work.  Of course, I could just rip
out the display tag altogether and be done with it, but by doing so, I
would also sacrifice the us

<% } if (FooBarBean.isExistingColumn(1)) { %>
   
<% } if (FooBarBean.isExistingColumn(2)) { %>
   
   ...etc., etc...
<% } if (FooBarBean.isExistingColumn(29)) { %>
   
<% } %>



... and Java code to support this which is simply to hideous looking to
post in front of a family audience... (Russ happened to catch me
desparately trying to prettify the most hideous looking class of the
bunch!  There are some things which simply no combination of comments
can help :-).

So please, just shoot me already!  Either that, or help me with this
agonizing problem which is causing me to lose sleep (normally I sleep
late on Saturday mornings if I stay up late the night before).  Of
course, it doesn't help that in this case, I have variable columns which
may or may not appear (causing the need for the additional "if
(FooBarBean.isExistingColumn(x))" scriptlet code.  Even without that
problem though, it seems that I would still end up having to in line my
display columns with silly looking class properties like stuff00,
stuff01, stuff02, etc., all the way to stuff29 for each of my 30
possible data columns when I would normally write a much sexier loop
through an array (or even sexier - a collection) - all because Struts
logic:iterate tags don't seem to want to play with the display:column
tags!

We have tried asking Ed Hill about this problem, but Ed has been pretty
busy lately (either that, or it is entirely possible that our emails to
him at his email address posted on his web site are being lost in
mountains of junk mail - which is the problem I am faced with on one of
my more well known web site email accounts - making useful
correspondence with me almost impossible to that email address).  Ed,
are you still with us?

Anyway, as my code review approaches, I thought I'd try one last time to
spare this otherwise extremely powerful display tag library from the
hungry jaws of the code reviewers at work.  Of course, I could just rip
out the display tag altogether and be done with it, but by doing so, I
would also sacrifice the use of the display taglib's spreadsheet (XML,
XLS, etc.) file export features (along with potentially many other nice
features).  The business group at work would not be happy with the loss
of these features.

Has anyone ever had any luck using Ed Hill's display tag library with
the Struts logic:iterate tag?  If so, then please reply to this post and
also contact me directly at my work address ([EMAIL PROTECTED]).

Thanks!

Is pre-validation transform of input possible?

[Steve Peterson]

Greetings.  I'm just getting up to speed on the validation framework within 
Struts and have a question that I haven't been able to answer from reading 
the list or the docs.

Is it possible to apply pre-validation transformations to form 
parameters?  Some examples might be:

.  trimming whitespace from strings
.  converting dates from shorthand forms to longhand forms ("today" -> 
20021109)

RE: Dynamic Value for logic equal

[edgar]

The reccomended solution is use struts-EL (You need to be using the
latest version for the EL).

Start by putting your form field in the proper scope (you might be able
to do this directly in the EL with something list
${session.FormBeanName.getFormCountryCode} buty I am not sure of that).



In your code below replace USER.GETCOUNTRYCODE with

${countryCode}

My particular solution extended the WriteTag and added parameters to do
the lookup so you don't have so much logic in the JSP for something that
you do so often.

Hope that helps

Edgar

Subject: Dynamic Value for logic equal


Hello All,

I have searched the list for some time now and could not find a
conclusive answer for my problem. I am hoping someone else has come
across this and can help me.

When displaying information about a User, I need to display the Label
for a Country Code. This should be simple enough. However, the User bean
contains only the country code. To get the Country label, I need to
iterate over the Country Data static collection, which stores
information about each country as a LabelValueBean. This collection is
stored in session scope.

However, the problem is that while inside the logic:iterate tag, the
logic:equal tag does not accept dynamic value for the 'value' attribute.
The processing should be like this:







The USER.GETCOUNTRYCODE is the problem part. I have tried
value=''. This does not
work, as it seems that it is parsed as is by the compiler. I also tried
using bean:define for the country code and then passing that in but that
fails as well.

I ended up writing a scriptlet around it to solve the problem, but am
not convinced that it is the best way to go about it.

Any help would be greatly appreciated.

Regards,
Vikram

Upload corrupts file

[Roland Polzer]

Hi,

I have a case in which an uploaded file is corrupted by struts.

The file is only 20KB. You can get it from here:
http://home.arcor.de/polzer/testXP.doc

Byte 4097 (originally 0x00) turned into a 0x0A.
I suspect a buffer size of 4 KB and/or a 0x0A 0x0D problem ???

Supposedly this bug is fixed in 1.0.1, but I have tried 1.0.2 and 1.1b and 
it is still there.

Thanks,
Roland

I18n and Oracle Database fails

[Mr Alireza Fattahi]

Hi,

I did a lot about i18n but I still have problem. I do
every thing that was said in :
http://www.anassina.com/struts/i18n/i18n.html

Every thing works fine. Now in my action form I read
the form inputs and want to insert the data into
Oracle
tables. The data will be inserted in wrong encoding. 

I did the below test:
I entered a Farsi string with 2 charcters in my form.
After submit, In the action form, 
when I print the length of this charcter I get 2. But
shouldn't I get 4 as character length, because it is
all unicode.

Should I say oracle that I am inserting unicode? How?

Set selected value

[Mohan Radhakrishnan]

Hi,
 The selected value of a drop-down can be set by filling the String[] in
the form with the required values. But the values eventually come from the
database. So inside the form you have to have access to one of the scopes
where you could store the retrieved values. Is this how this is done ?
Accessing values like this just to set the selected value seems to be a
roundabout method. I am using collections in the tags.
Thanks,
Mohan
