Hi,

Have you considered using the logic:iterate tag with a HTML 
inside.
Have a look at the example app provided with Struts. This uses the
iterate
tag. This might be a better option than  in your
situation.

Jon.

Subject: Struts - html:select options Question

Need help Users,

This question is pertaining to html:select tag.
I have a situation where I have to present a table of options where
each row
contains three columns of data
to the user. And there may be 100 such rows at any given time. 

Since there is no tag available to present the table directly in
struts, I
am using html:select tag by reformatting 
the three rows into a single row and using the html:select tag.

and the code looks as follows.


  
  

where list is a Vector that contains Strings in the form instance
gLMaintenanceForm.

It works fine and displays the resulting in display of one string per
each
item.
The only problem is it is squeezing out all the white spaces from the
string
that I present to the user.

For Example, If I want to Display "A  B   C"  as one
option
in the select list it only displays
"A B C" 

I even tried to use   instead of spaces like
"ABC"
it is displaying
"ABC"

If anyone knows the solution to this problem, Please help me out !!!

Thanks
Phani Paladugu

Best way to write Export files

[Alvin Kutttikkat Antony]

Hi there,
 I have to write export files to an another server.The code I am  using is 
not seams to be working fine .Some times it rewrites on an existing file.I am giving 
my code sample here

 access = ACCESS_WRITE;
long time = System.currentTimeMillis();
long timeSpawned = time;
// this routine tries 30 seconds
// to open a file, if not successful
while(!isOpen && (((timeSpawned-time)/1000)<30))
{
timeSpawned = System.currentTimeMillis();
try
{
out = new BufferedWriter(new FileWriter(filename,true));
isOpen = true;
}
catch(IOException e)
{

}
}
}
if(isOpen)
{
String line = "";
for(int i=0; i

ReQ: Only one logged in session at a time for each user

[Alvin Kutttikkat Antony]

Hi there,
I am too interested on this.The suggestion is good.How can I get 
session object from the Id.I think one way is through HttpSessionContext class. I 
found this class has been deprecated.
any other way to achieve this
Alvin




 second time, that you invalidate the *old* session 
and let them continue with new one. I've seen that approach used 
on a large public web site.

You can call the HttpSession.Invalidate() method, if you are not using Session any more

Setting a attribute from a page having no html:form ?

[Alvin Kutttikkat Antony]

I am using a jsp page as template for manipulating the iteration for different user 
data objects, 
so I have to save   the color value each time  getting out from this page to avoid 
getting the same color for adjacent lines of a table.
For this I have setter and getter in the bean class and I tryed 




<%if(color.equals("#ececec");
color="";
  else
 color="#ececec";
  %>
   


but it is not working through

I tryed  also by




is there any way to use "pageContext" or by some way else?


any help would be appreciated

>>> [EMAIL PROTECTED] 12/03/01 02:43pm >>>
Hi All,

Though I still have much existing material to read in the STRUTS mailing 
lists (thanks again for your help Jon!), I have come across three 
interesting solutions to dealing with automating or centralizing the 
translation of data from Action Forms (presentation layer) to Value Objects 
(business layer) and back again. Here are the three approaches:

Translation Pattern: 
http://www-106.ibm.com/developerworks/library/j-jsppatt/?dwzone=java&dwzone=ibm 

Using Property Editors: 
http://www.onjava.com/pub/a/onjava/2001/11/07/jsp12.html?page=2 

Using Code Generation: 
http://www.javaworld.com/javaworld/jw-11-2001/jw-1102-codegen.html 

The current one that I have seen referred to in the mailing lists is using 
Reflection (which still may easily solve this in most cases) or some type 
of mapper driven by XML setup info. Here are the mailing list threads that 
I have found on it so far:
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg18315.html 
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg18373.html 
(an answer from Ted related to msg18315)
http://archive.covalent.net/jakarta/struts-dev/2000/10/0135.xml 
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg05437.html 

Two other related patterns that I have found are the:
View Helper: 
http://developer.java.sun.com/developer/restricted/patterns/ViewHelper.html 
Dynamic Value Object: 
http://www.theserverside.com/patterns/thread.jsp?thread_id=2722 

I was curious what people thought of these solutions and what other 
solutions they had come up with.

This is an area that I really want to automate and that I really want to 
have a couple of solutions for (since it could generate a great deal of 
code that I REALLY don't want to have to rework if I find that the solution 
is no good).

Thanks for your thoughts and comments!
Allen
