RE: Caching Problem
Hi David You got the problem right well i have tried using only the last line of your code response.addDateHeader(Expires, 1); in my code it does not work maybe this will solve the problem. Hi Dinesh, Not sure if this is what you mean, but here goes: If you set the following headers into the JSPs response, the page will not be cached. Use the following scriptlet in the page to take care of this % response.addHeader(Pragma, NoCache); response.addHeader(Cache-Control, no-cache); response.addDateHeader(Expires, 1); % Take a look at http://www.redbooks.ibm.com/pubs/pdfs/redbooks/sg245850.pdf Section 6.5.6 for more information on this subject.

National characters don't reach Action class correctly
Hi,
I need help on this:
Problem is, I can see national characters on jsp pages correctly, but when I
post data to an Action, the string gets messed up. I couldn't find related
info in the archive.
Related lines on my jsp page:
%@ page contentType=text/html; charset=ISO-8859-9 %
html:html locale=true
FORM METHOD=POST ACTION=UpdateWoplan.do
INPUT TYPE=text NAME=fieldname size=5
value=bean:write name=wpl property=laborhrs/
/FORM
(I had to use the FORM tag because I have indexed fieldnames)
And my Action class looks like:
public class UpdateWoplanAction extends Action {
...
System.out.println(request.getParameter(fieldname);
}
I cannot get the correct string here. Instead I get s for national
characters like ÐÞðþ.
I couldn't figure out where the problem is - in Struts or in Tomcat. But I
did a test without using Struts, and the correct string is recognized by a
servlet then.
Any help will be very much appreciated.
Thanks,
Turgay.

FormTag-problem, bug or a feature?
I have a problem with the form-tag action-attribute when I use newer builds of struts. Is it a bug or a feature? maybe a buggy feature... Before, the action-attribute was not touched i.e. what one wrote in the .jsp-file was the same that came out after the taglibs rendering. Now the taglib tries to be clever, it is putting the web application name in front of what's in the action-attribute. An example might be more clear: Imagine a web-application with the name of web-application. We look into the form-tag of a .jsp-file e.g. dothethang.jsp: Earlier versions: html:form action=something.do name=someForm type=this.is.the.type.someForm was translated into: form name=someForm method=POST action=something.do Newer versions: html:form action=something.do name=someForm type=this.is.the.type.someForm is translated into: form name=someForm method=POST action=/web-application/something.do So why is this a problem? Well, this is a major problem if you have a proxy webserver with pathtrim of the url. e.g. if the original url is www.someplace.com/place1/web-application/dothethang.do the proxy might filter it so the servlet-container thinks the url is www.someplace.com/web-application/dothethang.do. If we look at the form-tag examples above the older version will post the form to www.someplace.com/place1/web-application/something.do while the latter will post the form to www.someplace.com/web-application/something.do ! Is there anyway this might change? This is quite a disaster if you use proxy webserver with pathtrim. Erik __ Do You Yahoo!? Yahoo!

Re: struts-template and MVC
Hi Dan,
Struts 'actions' do a forward at the end. This forbid to insert an action in a
template, because you can't do a forward once you have start to write the
request response.
A solution to your problem is, using Components implementation, to replace tag
template:get name='body' / with following :
template:useAttribute name=body classname=java.lang.String/
bean:include id=bodyStr page=%=body% /
bean:write name=bodyStr filter=false/
It may be interesting to be able to insert a page through an action, as you
propose. This is not very hard to implement with Components. Need to look at
this possible behavior more closely.
Cedric
P.S.: If you want to try immediately your solution with components, you can do
following quick and dirty code change in component.ComponentActionServlet.jsp :
In method processForward(...), at the end of the class, change call to
rd.forward(request, response); in :
try
{ // original behavior
rd.forward(request, response);
}
catch( IllegalStateException ex )
{ // Response already committed : do include
rd.include( request, response);
}
After that, you will be able to 'insert' an action from a template (but there
will be some problems if your 'action' forward to a definition name).

When I do that, I get an exception (which makes sense).
I'd like the best of both worlds by providing the templating capability and
still keeping my action-based web site. I was thinking of extending the
template:put tag to accept something like this:
template:put name='content' action='/displayRoles.do?type=external'/
That way, the action class will execute and eventually forward itself on to
the success page defined in struts-config.xml.
So, did I miss something here? Is my analysis of this situation right? Are
people using struts-template in a capacity other than a layout/presentation

got it all right, is there any interest in seeing this type of extension?

Problem Combining Struts And Homegrown Taglibs
We're having a problem using custom JSP tags with Struts that we're hoping someone can help with. We have two JSP pages: one that uses a Struts taglib and another that uses both Struts taglibs and a home-grown taglib. When we enter erroneous data into the page that only uses the Struts taglib, the framework returns an HTML page that displays the original form and data, plus the appropriate error messages. This is the desired result. When we enter erroneous data into the page the uses both Struts and homegrown taglibs, the framework returns an HTML page that displays the original form elements WITHOUT THEIR DATA, plus the appropriate error messages. We'd like the behavior to be like the first case, where the data is sent back along with the form elements. Can anyone explain why using a homegrown taglib might have caused this? Is there something in the custom tag API that we've missed? Thanks - MOD

Re: Design Suggestion
This question has already been debated in struts-dev in Nov; 2000. Unfortunately, online archive is not available for this thread. I join a copy of Craig McClanahan response. Cedric Craig R. McClanahan wrote: Cedric Dumoulin wrote: I would like to know why Struts uses base classes rather than interfaces with default implementations. As example, I am interested to know why ActionForm is an abstract class rather than an Interface (as in previous Struts versions). Could you explain me the reasons ? From my perspective, there are a couple of reasons that ActionForm is turning into a class instead of an interface: * EXTENDABILITY. Adding a new method to an ActionForm interface (in some future version of Struts) will cause any application's form beans to become incompatible -- unless they happened to implement the convenience base class that was provided. With ActionForm as a class, the only beans that are incompatible are those who have a method name clash. * CORRECT USE. If ActionForm were an interface, you would be tempted to use existing data beans as an ActionForm. IMHO, ActionForm is part of the presentation layer (for reasons that have been discussed on the mailing lists previously) and the provided APIs should encourage using it that way. For my point of view, it seem that using base classes rather than interfaces close some doors in this case : With a base class, you have to extends the class, which forbid any others classe inheritances. But, an ActionForm is used to expose properties from, lets say, business logic objects (BO). So, you must implement your action form with a delegate of your BO. If later you modify your BO (customization for a new client), you need to modify your action form. This will not happen if your action form can extend the BO (or its data representation), and use a delegate for the ActionForm interface. So, why closing this possibility ? Do I miss something ? Consider that your business object has property setters that match the form fields (a very typical case). Do you have any internal validation in your setters to, for example, disallow a null or zero-length value for a required field? If you do, then this bean is *not* appropriate for use as an ActionForm - because the API contract for an ActionForm is that it faithfully represents the input that the user submitted (so that it can be reproduced), whether or not that input is semantically valid. There are additional problems with the fact that -- especially if you use EJBs as your business objects -- you are starting transactions (and potentially locking resources in the underlying database), when the user may never come back. Applications will scale better if you don't start initiating the database transactions until a semantically valid input has been accepted. Cedric Craig McClanahan

RE: Cannot get request dispatcher for path http://cnn.com ?
Try changing step 5 to the following; forward name=step5 path=http://cnn.com/; redirect=true/ The javadoc for the ActionForward class says the path should be the Context-relative URI to which control should be forwarded, or an absolute or relative URI to which control should be redirected.

I feel it's a good separation of business logic from presentation, and that it follows the principles of MVC pretty well. Now the GUI developers are looking to integrate all of my very ugly HTML pages into a common look and feel. I thought that the struts-template mechanism would be perfect. I can define my header, sidebar, footer and dynamic content using this library. However, I noticed that the struts-template mechanism seems to be based on JSP pages, as opposed to actions. For example, the InsertTag class' doEndTag method calls pageContext.include, so I can't simply specify: template:put name='content' content='/displayRoles.do?type=external'/ When I do that, I get an exception (which makes sense). I'd like the best of both worlds by providing the templating capability and still keeping my action-based web site. I was thinking of extending the template:put tag to accept something like this: template:put name='content' action='/displayRoles.do?type=external'/ That way, the action class will execute and eventually forward itself on to the success page defined in struts-config.xml. So, did I miss something here? Is my analysis of this situation right? Are people using struts-template in a capacity other than a layout/presentation manager? Would the Components framework by Cedric solve this? Finally, if I got it all right, is there any interest in seeing this type of extension?

ActionForm Instantiation
I am using instances of my ActionForm for showing a list prior to showing
the detail. I do this because I don't want to duplicate the data
structures.
To better explain, I have an ActionForm called ProfileForm. I have a jsp
that uses ProfileForm to display and edit in the struts fashion.
To get to the edit jsp, I have a listing jsp. I used multiple instances of
the ProfileForm class to show 25 profiles at time. This actually done in my
ListProfileAction as such:
for ( int i = 0 ; rs.next() ; i++ ) {
profileEntry = new ProfileForm() ;
profileEntry.setServlet(getServlet()) ;
profileEntry.setProfileno(as.getInt(PROFILENO)) ;
try {
profileEntry.queryMaster(mapping, request) ;
} catch ( Exception e ) {
throw new ServletException((ProfilForm): + e.toString())
;
}
profileEntry.setSeq(Integer.toString(i % 2)) ;
profileEntry.setRecordStatus(QUERIED) ;
profileList.add(profileEntry) ;
}
I get a NullPointerException on the try/catch block. It appears to be
because the ProfileForm instance (which extends ActionForm) is not being
initialized correctly. Am I missing anything that will make an ActionForm
fully initialized?
I know this might look strange, but besides object reuse, another
implication here is to fully populate my forms before they're are shown in
detail. If this just isn't possible, I'll probably just try going about
this differently. But it'd be so cool to reuse my objects in this manner.

RE: Forwarding to a specific target frame
Hi,
I believe that what you are asking for cannot be done by the server.
This is because the server cannot push anything without the browser
requesting it.
It is the browser's decisions to output the data (html page, ...) in a
particular frame (the server has no control over this).
You usually use the target attribute in an a href= ../a tag to
accomplish this.
There is also a target property that can be found in the form object
using client side javascript.
example:
html
head
script language=Javascript
!--
function redirectToFrame(form) {
// This will cause all feed back from the server to be sent to the frame
// specified by the target property.
form.target=mainFrame; // Specify the window or frame name
form.submit();
}
// --
/script
/head
body
html:form
html:submit ... onclick=redirectToFrame(this.form);/
/html:form
/body
/html
I'm giving you this information from the top of my head so you may need to
tweak this a little.
Note: After the submit operation the target remains the same (that is
mainFrame) so you must find a way to set it back to the original target
after you have retrieved the data you submitted for.
There may be other alternatives that I am not aware of.

Objet : Forwarding to a specific target frame
Is there a way to get a struts action to forward to a particular target
frame? I have a page which contains two internal frames (iframes). One of
the internal frames contains a form. When this form is submitted or
cancelled, I want to display a different page in my main frame. What is
currently happening, is that my forward ends up putting the forwarded page
my iframe. I have a feeling that I'm somehow going to have to restructure
my page, but that will be really inconvenient to do. If there is anyway to
get a forward to go to a particular frame target, I would love to hear how
to do it.
Thanks.

RE: Radio Button question
Shane, It works for me. The value in the Radio Button is dynamic. I am at present setting an index for each Radio Button. When the user submits information back, i know what index it is based on the value selected in the Radio Button. I then lookup in the ArrayList on this index and get my correct object to deal with my logic.. In your case you are holding the values of the Radio Buttons inside the database. You might want to call a method with an index and the method will return the value based on the index you send in. A brief example would be.. % int i = 0 ; % logic:iterate id=groupsList name=statesBean property=states html:radio name=statesBean property=selectedIndex value=%= statesBean.getIndexedValue(i) % / % i++ ; % /logic:iterate where the property is the actual value you are trying to compare and value is got from the database... This is not pretty but it serves the purpose whether it is a Radio button or a Checkbox...Struts compares the property to the value. If both match then the checkbox is checked, else the checkbox will not be selected... Hope this helps.

Re: Trouble setting properties of an ActionForm bean
As far as I know, the value passed into the setter method must match the
value returned by the getter method. It will not work otherwise.
Could you return 'true' or 'false' as a String? If you are setting a value
of a field, it should work.

you need to use different quote characters to avoid conflicts.

Very strange. I tested to see if my cookie was set properly:
% Cookie cookies[] = request.getCookies();
String phonecookie = nothing;
for (int i=0; i cookies.length; i++) {
if (cookies[i].getName().equalsIgnoreCase(checkout_phone))
phonecookie = cookies[i].getValue();
}
%
input type=text name=phone value=%=phonecookie% /
And I obtained the proper value.
Thanks for any help.

Re: page flow control
Search the archives for implementing Wizard style interfaces. There have been several posts on how to accomplish it. - Original Message - From: Nathan Coast [EMAIL PROTECTED] To: struts-user [EMAIL PROTECTED] Sent: Wednesday, May 16, 2001 10:09 AM Subject: page flow control Hi, In the site I'm developing, there are sections that have forms on consecutive pages, I want to guarantee that pages are navigated: page1 - page2 - pageN. At the same time allowing back and forward navigation to change values entered on previous pages. After the last submit, the only valid page in the sequence is then page1. I've had a look at the Struts Token functionality but I don't think it can support this functionality. Is it possible with Tokens or some other way? Thanks in advance Nathan

Re: National characters don't reach Action class correctly
Hi! Yes, that really helps, thank you. I also found the same thing at a message in java-apache-users archive at http://www.geocrawler.com/archives/3/440/2000/2/0/3373820 The interesting thing is, this doesn't happen if the Struts html:form tag is used - then I get the correct characters. I am trying to figure out why, digging in code for org/apache/struts/taglib/html/FormTag.java Thanks again, Turgay Zengin. - Peiqiang Han wrote: Turgay, If you use Tomcat 4.0 (servlet spec 2.3), you can just wirte: request.setCharacterEncoding(ISO-8895-9); System.out.println(request.getParameter(filename)); If you use Tomcat 3.2 (Servlet spec 2.2), String data = request.getParameter(filename); byte[] raw = data.getBytes(ISO-8859-1); System.out.println(new String(raw, ISO-8859-9)); hope this helps, Peiqiang Han Turgay Zengin wrote: Hi, I need help on this: Problem is, I can see national characters on jsp pages correctly, but when I post data to an Action, the string gets messed up.
