Writing complicated HTML with embedded bean data
I'm rather new to Struts, and have done quite a bit of
reading, but am just now getting down to some experimental
development.
One of the issues I'm trying to deal with is how to generate
things like HTML links without resorting to embedding
scriptlets.
For example, let's say that I have a bean named 'product'
with two properties: id and title. I would like to generate
a link like this:
I don't want to resort to using a scriptlet to get the
product id embedded in the link. So far the only solution
I've seen is in the struts-example app, which uses a custom
tag in a similar situation to avoid the scriptlet approach.
That seems like overengineering to me (or maybe I'm just too
lazy).
It seems to me that the tag might be easily
adapted to solve this problem. I would like to be able to do
something like this:
In ApplicationResources, define the following:
product.link={1}
Then, in the jsp file:
I'm using { } in the arg attributes to indicate that the
text of the argument should be retrieved from the bean using
the struts property evaluation system.
What think ye?

Re: Performance of of action?
I think there is no significant performance differences between "calling an action", using or using . Once the jsp page is compiled, all these solutions result in java method calls. Differences are more on how you architect your jsp pages. As you speak of 'sort of components" in your mail, you may take a look to the Components proposal, which can be seem as "extended templates", and will be smoothly incorporated in Struts 1.1 .

Using two tags is a good solution, but wouldn't it be nice
to have a kind of "if .. then .. else" feature ? Like :

Digester :"java.lang.InternalError: (Ex02) An error has occurred " AND"addCallParam"
Hello, It seems that addCallParam push a String on the stack, why ? It is very annoying for my program. How can I by pass that problem ? I would like to parse the following XML : 1/ first : I push my global object on stack (digester.push) 2/ on config tag : create configClassName object with nested attribute (new Object on Digester Stack with addObjectCreate and addSetProperty). Before automatically pop, I do a addSetNext to store newly object reference to global object. 3/ on connector end tag I would like to run a method with name and className parameters : so I use addCallMethod et 2 addCallParam on connector pattern, BUT addCallParam push a String on stack and my previous AddSetNext is now launched on that String instead of the global object Thus I receive that InternalError !!! I can't believe it is impossible !! Does somebody have any idea ? Please, Thanks, Sébastien - Un courrier électronique n'engage pas son émetteur.

null or empty string
Hi, I have written a dynamic validation routine which is based upon only validating the fields that have been submitted and then "mopping up" later. This only works because you can tell the difference between a field being submitted and left blank (value = "") and a field not being present in the request (value = null). This is true for input type="text" but is not true for input type="checkbox", has anyone come accross this problem before? any solutions ideas? Cheers, Andy S

Re: AW: null or empty string
This is the behaviour as I understood it and it leaves no way to tell if a user has left a checkbox selection blank without knowing specifically that you were exepecting it on that page, something my current design dosen't enforce with other types of input (nice and dynamic). I may be able to extend the Form tag to include some onSubmit csjavascript that searches through fields and makes sure a blank string is submitted if it has been left unchecked. We shall see.

Re: null or empty string
Andrew, CheckBox values are retrieved using the getParameterValues method on the the HTTPServletRequest object which returns a string array. Most other input types simply use the getParameter method which work as you describe below.

AW: AW: null or empty string
Ok, I understood. I think you need a little workaround ... Maybe try this. Inside the form I would use a hidden input-field that value is a comma-seperated list with the name of all checkboxes inside the form. This field will be submited with the form. Now you know which checkboxes are inside the form and can ask the request if it is present. If you use everytime the same name for this hidden field (containing the names of the checkboxes), you can make you validation-routine very dynamic and you do not need JavaScript ! cu Frank > -Ursprüngliche Nachricht- > Von: Andrew Steady [SMTP:[EMAIL PROTECTED]] > Gesendet am: Donnerstag, 19.

bug? resource bundle is not automatically changed
Hello! We're using the tag to display localizable messages. The message is displayed in the default locale which was active when the web server was started. I thought struts would use the correct resource bundle automatically! Isn't that true? What we did to get the correct language was session.setAttribute(org.apache.struts.action.Action.LOCALE_KEY, request.getLocale()); in the jsp pages. This works, but I suggest struts should do this automatically. Greetings, Uli
Performance of of action?
I'm trying to decide how to structure our app. We want to use templates to separate the layout from the content, and we want to use the Struts framework to separate the business logic from the presentation. I've been converting several parts of our site and am happy with the results.

Re: Performance of of action?
I am not sure if I understand your question correctly but have you check the struts-template web application example that comes with the struts framework? This might give you a good indication on how to build a good template using Struts. You can also create custom tags instead of having Java in your jsp...

RE: Performance of of action?
Hmmm, maybe I made it too complicated by mentioning templates...that really isn't my question. My question is more about the performance of doing a of a JSP file versus an Action (that is, something like "header.do"). Another aspect of my question is what are the negative implications of pulling the business logic out of the JSP and into a custom tag as opposed to an Action class. If you do this, the architecture of your app becomes a little more complicated and a little harder for others to understand, doesn't it?

does not display errors
Hi All,
I am trying to use the ActionErrors collection to send the actions back to
the browser
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError("error.user.create.failure"));
// Report any errors we have discovered back to the original form
if (!errors.empty()) {
saveErrors(request, errors);
return (new ActionForward(mapping.getInput()));
}
But no errors are being displayed on the browser.
This is snippet of my jsp code:
User Name:
Quantity
Create
Can Any body tell me what is going wrong here? I declared my error key and
value in the resource file.
Also no error is being thrown by the JRE.
Thanks,
Uday.
Re: Writing complicated HTML with embedded bean data
> You can use the html:link tag to pass parameters.
That's true -- ! The html:link also solves
other problems (like including the session id when url
rewriting is in effect). Thanks for pointing this out.
However, in cases where there is not a struts-specific
solution, there is still a need to be able to embed bean
info in HTML tags. For example, I have a case where I need
to build a link tag and get the entire link URL from a bean
property; I don't believe there's an attribute of
that handles situations like that.
>From my limited experience, it seems that, although Struts
can strive to provide the features for 80% of cases like
this in the html taglib, there will always be that other 20%
to deal with, and I'm looking for a general-purpose solution
for those.
I actually just whipped up the implementation for my
proposal just for fun and it works nicely. But I don't want
to go off and use something nonstandard if there's a better
'standard' way.

Checking User log in in a JSP page
This question is regarding where to provide the check for user logged in, should it be done in the Jsp or the actionServlet. While I have proposed the Jsp since you may not want a user to see a page if they are not registered, others claim that it should be in the actionServlet. Their claim is that checking for user logged in is business logic (even though its done using a tag) and there should be no business logic in a Jsp page. Further allowing this you open the Jsp page to adding more business logic. My question is where do you draw the line on the business logic that can be provided in a Jsp page. What are the thoughts of designers out there. Thanks Irfan
Error creating Action instance for path

how do I report exceptions during Action setup?
Hello, All of my Actions may throw Exceptions during their initialization phase (during setServlet). setServlet isn't set up to throw any Exceptions. What happens if my Action class is not able to initialize properly (can't get a reference to my EJBs or a DataSource, as an example). I would want to somehow signal to the ActionServlet that this Action is invalid. If I can't throw an exception, is there a way to notify the ActionServlet that this Action is invalid? Thanks very much for any tips and pointers! Seth Seth Ladd | Software Engineer, Product Development Brivo Systems, Inc. [EMAIL PROTECTED] Confidential and Proprietary, Brivo Systems, Inc.
Re: Checking User log in in a JSP page
I would argue that logging a user in is business logic. However, the user state (i.e. whether the user is logged in) is part of the model - a "permission denied" message is the appropriate view of the model when the user is not logged in; thus this belongs in the JSP. I check permissions at the top of all of my JSP's - I don't feel that this has caused business logic to leak into the pages. However, if clients can post directly to your actions the actions need to check permissions, too (since the post might not have come from a valid page).

Re: struts not reading properties file
In your web.xml file, does the tag point to the correct location? ... application com.myResources.dictionary The properties file does not need to be in both places. You could either place it the classes directory, or jar it up with the rest of your classes.

Need help with logic:iterate :)
Hi, I am trying to get a handle on the logic:iterate tag. I have an object in application scope under the key 'storeroomList.' There is a vector of objects under the property 'storeroomList'. Each one of the objects in this vector has a property 'name.' What I am trying to do is go through the vector and print out the names. I have attempted the below but the only storeroom name to be printed out to the screen is the last storeroom. I traced the execution of the iterate class and it looks to be getting the correct data, going through each element of the vector and pulling out the name property and then looping through all the elements without printing them to the screen and then the bean:write is called. Any help is as usual greatly appreciated. Oh, bonus question.. Lets say I only wanted to print out a particular storeroom. Iterate through the vector but only print the storeroom that had the name "main." Regards Alex
Tomcat+Apache Struts problem

RE: struts not reading properties file
Hey G.L., You might also want to check if the web app is configured properly on Orion. I would try adding a class to the classes directory of your web app and then try using the class in a tag. If it can't load the useBean class then I would guess it is a Orion configuration problem. In addition, when you say cais.properties is located in /WEB-INF/classes is that for the default web app or named web app?

Re: Need help with logic:iterate :)
You're closing your first element, so the iterate never gets to the bean:write until after the loop is finished. You have: It should be (note the lack of the trailing slash): If you only want to do something for one specific bean, then use logic:equal inside the iterate tag. -- Dan Miser http://www.distribucon.com >From: "Alex Colic" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: "Struts" <[EMAIL PROTECTED]> >Subject: Need help with logic:iterate :) >Date: Thu, 19 Apr 2001 15:50:44 -0400 > >I >have attempted the below but the only storeroom name to be printed out to >the screen is the last storeroom.

RE: Need help with logic:iterate :)
Your tag closes itself before it gets to the tag body. i.e. I made this mistake a couple times too so don't feel bad! On your bonus question, your JSP shouldn't be performing business logic, the bean should be. Create another getter on your bean for the specific thing you want to display. Alternatively, inside your you could wrap a tag around your and conditionally display a particular value within the iteration. Roman -Original Message- From: Alex Colic Sent: Thu 4/19/2001 12:50 PM To: Struts Cc: Subject: Need help with logic:iterate :) Hi, I am trying to get a handle on the logic:iterate tag. I have an object in application scope under the key 'storeroomList.' There is a vector of objects under the property 'storeroomList'. Each one of the objects in this vector has a property 'name.' What I am trying to do is go through the vector and print out the names. I have attempted the below but the only storeroom name to be printed out to the screen is the last storeroom. I traced the execution of the iterate class and it looks to be getting the correct data, going through each element of the vector and pulling out the name property and then looping through all the elements without printing them to the screen and then the bean:write is called. Any help is as usual greatly appreciated. Oh, bonus question.. Lets say I only wanted to print out a particular storeroom.

In my application all important stuff (retrieving/storing data to be displayed in my JSP) is done by the controller, bypassing the servlet is possible but doesn't make much sense. Most likely the user will not see more than some ugly nullpointer exceptions because beans are missing or whatever. There's no "official" way to get to these pages directly... so - who cares?! :) Regards, Tobias

I would assume if you could somehow catch the ServletException that wraps
it, you could get the root cause and see if it's an instance of
org.apache.struts.upload.MaxLengthExceededException and go from there.
Could that work inside of a jsp error page? Like this:
<%@ page language="java" errorPage="true" %>
<%
if (exception instanceof ServletException) {
Exception rootException = ServletException.getRootCause();
if (rootException instanceof MaxLengthExceededException) {
//do your thing here
}
}
