Keeping tags actually renders perfectly well for me right now (no exceptions, no apparent problems with the resulting page), but with peculiar results for the actual logic it's supposed to be doing, so I wasn't sure whether that was a configuration issue making it not evaluate correctly, or a Struts1 configuration relic making it still quasi-functional.

Re: problems when using logic tag with jsp scriptlet
Hi Laurie, Thanks for info and help. The problem looks rare. We load the example coming with Struts (struts-mailreader), it works, which use struts. That means application server is OK.

We think there is only a little issue somewhere block action loading when it starts, which only applys to our application since other works (struts-mailreader).

DynaValidator and logic-tag
Is there any way to show appropriate errors using DynaValidator? I have a form with 3 fields, one for the username and two fields for a password. When you enter no values, a global error must be shown to the user. When the user enters an invalid character for the username, a messages that states that the user entered an invalid character should be shown in the web browser. When he enters a username that is already taken, the browser should show that. That also counts for the two password fields. A message should be displayed when they are unequal or that they don't correspond to the rules (at least one number and special sign). I created my Validator-class, but I really don't know how to accomplish the situation above. Right now I'm drowning in a logic:messagesPresent and notPresent construction and if I have some sympathy for those who need to make some changes to this code, I'd have to replace it with a more clear and more understandable construction. Adding the whole validation-flow to one field is a solution, but I don't think that's a good one. You stuff everything in 1 method and that's that. Is there any other way to do this? I have validation on 2 methods, username and password. This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information. If you have received it in error, please notify the sender immediately and delete the original. Any other use of the email by you is prohibited.

Just use a sequence of if-thens, preferably using JSTL thingies. Do you have an extensible list of possible roles?! If so I would consider using a different mechanism than this; it will only lead to tears. Perhaps an inclusion of a separate page, the name of which is built using a known string concatenated with the role, etc. Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Conditional Statements (if/else) Using logic tag
Filter the List before sent to jsp, can you do it? or you must do it in
jsp?
you can implement your own custom tag extending iterate.
Other solution is to define a variable in jsp with c:set when you found
and item, and only print when variable isn't set or false.
Take a look to jstl common tags.

Re: Conditional Statements (if/else) Using logic tag
I guess my problem is larger than using an if/else statement. I figured how to
do that, but I'm iterating over a List in the JSP, and want to be able to exit
the loop whenever certain item exist. I don't suppose there's a way to do that,
is there?
My requirement in a nutshell: the List could have role1, role2, and role3.
But I can only print one role on the screen. If the list has multiple roles,
then my loop will show all of them. I want to be able to exit the loop after I
find the role that I'm looking for.

Re: logic tag - to check form elements
Hi Raghu What's the name of the form bean? Let's assume it's "myformbean" for the example: ... Use the 'name' parameter to reference the form bean name. Use the 'property' parameter to reference the property. Note, you will be testing the value in the form- bean, not the value in the hidden html field. Do you need to change the value of the hidden field? If so you will need to use Javascript to perform this test and modify the displayed values.

For an error page, "exception" is an implicit *scripting* variable. Meaning it's
available to scriptlets (<% %>) and scripting expressions (<%= %>). It is not
an implicit JSTL/EL object. However, there are a number of request attributes
that should be set by the container. Here's how you might get at them with
JSTL:
<%@ page isErrorPage="true" contentType="text/plain" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
Error Page:

Hi,
As suggeseted I switched to JSTL 1.0
I'm running my application using Tomcat 4.1.30.
Below is the content of my error page.
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%@ page language ="java"
import="java.util.*,javax.servlet.http.*"
isErrorPage="true" %>
Exception is InvalidParameterException.
Exception is not InvalidParameterException.
If I'm not wrong 'exception' is an implicit object available to a JSP.
But I never see the when part of content getting printed even if
InvalidParameterException
is thrown.
I also tried
But this time it encountered some parsing error.
How exactly an object instance is passed to a JSTL tag? I'm not very clear on
that.
Let me know where I'm doing wrong.
Regards,
Ashutosh

Re: Help with Struts-Logic Tag
Sorry slight typo - try something of the form: Note the <%= at the start of the name value. If you look using Google you can problem find a simple tutorial to explain all about the logic tags but put simply the above statement checks for the presence of a bean named the value of Konstants.SESSION_USER_KEY. If this bean is present then it will evaluate the nested content of the tag. In most tutorials (I'd imagine) you'll see the value of the name attribute will be something like "user". By using <%=Konstants.SESSION_USER_KEY%> instead you're telling it to look up this value. Hope that helps you a bit.

Re: about logic tag
opps. Didnt see this post when I replied just now. The syntax seems ok. When you say its not producing results, is there any error message or stack trace, or is it just that that part of the page is blank? If blank it sounds like the results vector is empty. I presume you initialise it in your Action before forwarding to the view? Given that you say the actionform is being recreated I rather suspect that you may inadvertanly be using a redirecting forward to forward to the JSP. Check your struts-config.xml and make sure that the ActionForward pointing to the JSP has redirect="false" set.

Re: logic tag
Sorry mate, you going to have to be a bit more specific about the problems your having, and precisely what result it is that you are actually trying to achieve, as we are having some trouble understanding the question! I am having a vector object in jsp In a request or session attribute I presume? An ActionForm's two instances are stored in that vector This I dont understand. The struts methodology involves one actionform per request, and its instantiated, populated and put into the request )or session) by the RequestProcessor. Are you doing some custom handling to support multiple actionforms per request or did you mean something else? How can i produce the results What is the result that you are trying to produce? I guess you want to iterate a vector and output the contents? At its simplest you should be able to do something like: Change "myVector" to the attribute key that your vector is stored under in the request or session. "myProperty" refers to the name of the single variable you wish to output. It needs to have a single getMyProperty() method (change names as appropriate). hth Andrew ps: The article at: http://www.catb.org/~esr/faqs/smart-questions.html has some advise on how to improve your communication when asking questions in lists like this, and is well worth a read if you are new to such forums.

Re: FW: property element in logic tag
I think you have a few extra layers of nesting. What exactly are your
system.out checks? What's being called in the custom tags is the same as
session.getAttribute("PersonStatus").getPerson().getCountryCode().getCountryCode()
The value portion of the tag is
session.getAttribute("CountryCode").getCountryCode()
See if that's what you want to be called. Based on your description, it
seems like the "person." is irrelevant and the second 'countryCode' may
need to be 'm_countryCode'

Hi,

PersonStatus is a session object that contains a nested object
countryCode of type CountryCode and the class CountryCode contains a
string m_countryCode.
There is also a session object CountryCode that is an arraylist of
different country codes e.g. "UK" is United Kingdom, "IE" is Ireland etc
I tried using

Null property value for 'countryCode', but I've done system.out checks
and the object is set with values.

I am new to struts. I have a question regarding logic tag.
I was replacing those if else if . end if stuffs with logic tags on jsp pages.
For example:
if num==1 {// condition 1

block 2;
}
Usually if condition 1 is true, condition 2 does not be evaluated. Now if I use
tag as follows:
(condition 1)
block 1;
(condition 2)
block 2;
It seems that condition 2 is always evaluated no matter what the result of condition 1 is.
That's correct.
It would be a performance penalty if this is the case. Am I wrong?
It is basically not possible to directly model an if-then-else clause
using XML syntax. The best approach I've seen is the one used in JSTL,
where the tag acts like a "switch" statement in Java or C:
... condition 1 results ...
... condition 2 results ...
... equivalent to a final else with no condition ...
On the other hand, does a "performance penalty" particularly matter,
even if it exists? If you're using JSP pages the way that Struts
suggests, you would only be using conditionals in the page to choose
which elements to render, probably based on some very simple conditional
tests, and the only thing your using is a little extra CPU on the web
tier (which is very rarely the bottleneck for performance in an overall
system).
I would generally suggest that you code for clarity and maintainability
first, and then worry about peephole optimizations like this only if it
turns out that your app is not fast enough, and indeed that doing
something about this particular case will actually make any difference.
Thanks for help,

Thats because of the jsp custom tag specification, that does not allow
data sharing between blocks.
