Re: new template tag framework
Sorry for this late answer, I was far away from a computer for near three weeks (somewhere in the tropics ...). Sure, I do not object to integrate part or whole of Components proposal, and I am open to any discussion to improve it. I have designed Components to be able to build pages by assembling "independent" and "reusable" pieces of jsp code. Later I have unified Components syntax with David's Template in order to not provide another tool, and because Davids Template has already been adopted. Now, components can be seen as an extended template proposal. It is an additional taglib that you can use if you need provided features. It uses some Struts utilities, but doesn't rely on Struts. The provided servlet extends the Struts one, in order to be able to "catch" include calls from Struts, and reroute them if needed. Provided servlet could be simplified if Struts servlet provide such a hook. May be one day ... It is the only intrusion in Struts. Cedric David Geary wrote: I think this is a good idea.

It certainly won't be added to 1.0 at this point. For 1.1, I'm certainly open to cool additions, and will be looking at this one closely.

A colleague of mine started seeing exactly the same problem today, but with Resin instead of WebLogic. I had never seen it before.

When we commented out a sizeable number of those tags, it started working again. Which particular chunk of tags we removed did not make a difference, which is what led me to believe it was related to page complexity. However, that's as far as I've got.

Redirecting the user
Hi!
I have a question concerning redirecting:
On our site we have a page with an input field and a drop-down-list-box.
Based on the value of the drop-down-listbox we want to redirect the user to
different servers. We also want to send the value of the input field as a
parameter for each redirect.
To do this I put the following code in my action-class:
if (valueOfDropDownListBox.equals("A"))
return new ActionForward("http://siteA?param1=" + inputFieldValue,
true);
else
return new ActionForward("http://siteB?param2=" + inputFieldValue,
true);
There will be requests with very different inputField-values (this will
cause the creation of lots of new ActionForward objects). Is this an okay
way to solve this, or is there a better way to do the redirecting with
parameters in STRUTS?
Greetings
Ken

RE: JBuilder Enterprise
I have set up JBuilder to mimic my tomcat environment. First I set up my
JBuilder project to build my classes in "/WEB-INF/classes" then I changed
the working directory to {tomcat_root}/bin (this is not required).
As for the Jars, I include them in the project so that the build can find
all the jars. In our final build struts.jar is placed in "/WEB-INF/lib"
where tomcat automatically picks up the jars.
Hope that helps,

Using Struts to achieve asynchronous comms
Hello all. I've been wrestling with an asynchronous comms problem (for almost a week) and am wondering if implementing struts can help. I'm developing a web application that'll send a message to a server, then wait for a response and display that response to a web browser (the client). The problem is, the server requires an indeterminate amount of time (from several seconds up to minutes, perhaps even hours in production) so the servlet must 'wait' somehow until a response is ready. Implementing blocking calls at the servlet level doean't seem the way to go and I don't think a producer/consumer pattern will help either. Still searching the archives (my connection is unreliable today for some reason) so my apologies if this has been dealt with already. Please point me to the right resources if possible. Thanks in advance for any and all replies. Greg
Re: Using Struts to achieve asynchronous comms
hi, maybe my approch is ridicolous but it would be very simple: szenario: 1. your client request servlet url. (your servlet stores the session id of your user (in any way) to remember him/her) 2. your servlets starts the process doing the heavy work (i suppose ;=) 3. your servlet sends *immediate* response, containing a html site with a meta refresh tag or some other code forcing the users browser to reload the site (== contact the servlet url), ie. every minute or so 4. every time the servlet gets contacted it checks if the working process is finished for the user. if not ready it sends the same html site again 5. finally if the user contacts the servlet again and if the result is available you redirect or forward him/her to the result page this is how i would do it probable joe At 18:08 07.02.01, you wrote: Hello all.

Re: specifying default values for forms
In Struts 1.1, we need to provide finer-grained control over this as part of enhanced validation processing (i.e. things like per-property default values and such). We're currently looking at ways of implementing user preferences, so that when ever we construct a given bean (for a specific form probably), the user's default values are set. Has any coding started on this / design been done as yet? My current thoughts are: a) Some sort of bean factory that could apply any suitable defaults, based on info in the session / our own classes -- maybe via some sort of framework hook. b) Same as (a) but maybe using a custom tag instead of jsp:useBean / c) Always enter an app / screen via an action, so that it can initialise the required beans, so that useBean never constructs the beans. Ideas? Ken.

There must be more public sites than this.There's http://jakarta.apache.org/strutsat least(although it doesn't do anything showy). Please help me explain to MVC-clueless colleagues and bosses why I am spending so much time getting into Jakarta Struts (as opposed to the superficially similar, released, commercial,freely downloadableJSP taglibs, like Allaire's JRun Tag Libraryor WDIG's TeaServlets).

Re: Not sure if this is clear but I wanted to keep it short:
Here is one of my examples:
logic:iterate id="category" type="com.ecs.com.struts.common.Category"
name="%= Constants.CATEGORIES_ARRAY_KEY %"
tr
td
html:link page="/showCDs.do" name="category" property="mapping"
bean:write name="category" property="categoryName" filter="true"/
/html:link
/td
/tr
/logic:iterate
The Category class is defined as follows:
public class Category implements Serializable {
private int categoryId = 0;
private String categoryName = null;
private HashMap mapping = new HashMap(); //mappings for link parameters
public Category() {
}
public int getCategoryId() {
return categoryId;
}
public void setCategoryId(int categoryId) {
this.categoryId = categoryId;
}
public String getCategoryName() {
return categoryName;
}
public void setCategoryName(String categoryName) {
this.categoryName = categoryName;
}
/**
* The Mapping HashMap that is passed to the LinkTag in the form
* tag library. The HashMap is a collection of parameters that will
* be used to make a query string and add it to the link.
*/
public void setMapping() {
mapping.put(Constants.CATEGORY_ID, new Integer(categoryId));
mapping.put(Constants.CATEGORY_NAME, categoryName);
}
public Map getMapping() {
return mapping;
}
public String toString() {
StringBuffer sb = new StringBuffer("Category[categoryId=");
sb.append(categoryId);
sb.append(", categoryName=");
sb.append(categoryName);
sb.append("]");
return sb.toString();
}
}
Hope that helps... I'm doing something a little more strange by using the
HashMap for a mapping, but it looked cool!

Forwarding to the same page
Hi, Is there a way for an Action class to find out which page/action called it ? Iam faced with a problem where the Action class should perform its work and forward the page back to callee page. Note - I cannot add any "forward" tags to this Action mapping because this Action is part of a framework. Any clues ? Thanks, Kishore
Re: Forwarding to the same page
You can call mapping.getInput() in your Action class. This will get you the URI that provided your input, and is what Struts uses to send you back to your input form if the ActionForm validation fails. -- Martin Cooper Tumbleweed Communications - Original Message - From: "Kishore Subramanian" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, February 07, 2001 2:40 PM Subject: Forwarding to the same page Hi, Is there a way for an Action class to find out which page/action called it ?

Re: Forwarding to the same page
You can use:
request.getHeader("Referer");
to return the referring page.
Or, we have a class that takes a request object and performs methods against it.
One thing that it does is return the referring page. (without the query string or
path).
This is the method from it
m_request is a member variable of the class...
public String getReferrer()
{
String sFullRef, sRefPlus, sReferer;
sFullRef = m_request.getHeader("Referer");
if(sFullRef == null) return "";
int iPos = sFullRef.lastIndexOf("/");
if(iPos = 0) {
sRefPlus = sFullRef.substring(iPos+1, sFullRef.length());
}
else {
sRefPlus = sFullRef.substring(0, sFullRef.length());
}
iPos = sRefPlus.indexOf("?");
if(iPos = 0) {
sReferer = sRefPlus.substring(0, iPos);
}
else {
sReferer = sRefPlus;
}
return sReferer;
} // ends getReferer()

I have an action class in which I've instantiated a bean, and called

do for bean:define, when all I'm looking to do is reference a bean on

When you say you want to "get at" that bean, what is it exactly that you
wish to do? For example, if all you want to do is render the value of
the bean (or a property of the bean) to the output page, you should use
bean:write instead of bean:define.
In bean:define, the "id" attribute tells you the name of the attribute
(and scripting variable) that will be *created* by this tag -- exactly
the same as the "id" attribute on the standard jsp:useBean tag works.
The "name" attribute, on the other hand, is the bean *from* which you
are copying the value to be created.

Re: Forwarding to the same page
Yes, you are correct, that's where it comes from. It's true that there's no guarantee that this is where you really came from, but it is where you'll go back to if your validation fails, and in the vast majority of cases, I would guess, you want to go back to where you came from to show the errors. ;-) -- Martin Cooper Tumbleweed Communications - Original Message - From: "Mike Campbell" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, February 07, 2001 3:21 PM Subject: Re: Forwarding to the same page "MC" == Martin Cooper [EMAIL PROTECTED] writes: MC You can call mapping.getInput() in your Action class.

link tag parameters problem
I have a two Struts link tags on a page. The first one sets a parameter but the parameter shows up on both links instead of just the first one.I am using Weblogic 6.0. Should the param* attributes be getting reset in the release() method of the link tag? When is the release method on a tag called? Thanks, Hal html:link paramId="orderId" paramName="order" paramProperty="orderId" page="/viewOrderDetail.do" %= "Order No. " + order.getOrderId()% /html:link html:link page="/createOrder.do"bean:message key="link.createorder"//html:link
An array in a form bean
I want to have a series of text boxes ( say 10 ) in a html page. I would like to use a formbean for this with an array for the text boxes. So they all go under the same name I guess. How should the getter and setter methods be? How would we have it in the html page?? What should be done in case the number is variable??? Thanks Hunt __ Do You Yahoo!?

property in form tag
Can we access arrays in form:form tag as form:form property="memberVariable[i]" / ??
