RE: help! confused over forms and errors and oooh, other stuff :-)
If I understand your problem correctly, then I don't think you have missed
anything. I would be interested to know how you would solve the problem in a
non-struts environment. Unless your item details object is in session scope,
then it will not survive across two requests, which is the root of the
problem.
I would persevere with your approach of putting the details object in the
form bean.
Have you tried using hidden form variables. E.g.
html:hidden property="item.name"/
html:hidden property="item.manufacturer"/
html:hidden property="item.price"/
html:hidden property="item.info"/
html:text property="insideLeg"/
etc..
This should preserve values across a validation failure. I don't know for
sure. If I get time today I'll have a shot.
Let us know.

Hi Guys,
I wonder if you could help me out a little please? I am in the middle of
developing a proof of concept app with struts. If this comes off the
company
could migrate away from a proprietary framework to struts, which I am in
favour of.
I seem to have confused myself over an issue regarding validation and
forms.
Ill give a simplified workflow as an example.
We have for all intents and purposes a generated product overview page
along
these lines:
*Wooden Throat Mallet59.95 buy
*Leather Uncle Frightener12.60 buy
*Vandal-Proof Toupee 99.99 buy
Which is generated from struts tags. The buys are links to a pages which
look something like buyit.do?itemid=50. The buyit.do action has
registered
a form in request scope. During processing, it looks up the full details
of
the itemid and places the resulting bean in request scope. It then creates
the form object, populates it with some default information and sets this
in
the request too before forwarding onto buypage.jsp
This displays the details of the item, and contains a form for entering,
say, credit card details:
*Item: Vandal-Proof Toupee
*Manufacturer: Lockheed-Martin Advanced Hairpiece Research
*Price: 99.99
*Additional Information: Also Invisible to Radar
*
* Inside Leg Measurement: _
* Credit Card Number:
* BUY {forwards onto checkout.do}
Which is all fine and dandy and displays correctly. Though what happens if
the form validate fails? If checkout.do has an input attribute which is
buypage.jsp then this will fail because the item details are stored on the
request has not been set up (it was done in buyit.do). I could of course
set the item details on the session, but if the user opened new browser
windows for the buyit link, then the session level object will be
overwritten.
If have looked into placing the details object onto the form bean as it is
populated, but will that property be preserved across a validate failing?
And how do I get at the properties of the form bean outside of the
hmtl:xxx tags?
Help !

Re: help! confused... now contains a proposal
Hi Hal, thanks for your mail
Yep that would be one solution if the population if the bean required on the
form page was 'static', but in the case I was referring too it needed the
item id to look up. I would imagine that it might be done by sending
actionforms with the id in backwards and forwards but this would become a
maintenance nightmare.
I reckon the way to approach this is to modify ActionForm handling. I would
add a field to this which holds the HttpServletRequest which gets set when
the form is created/retrieved in ActionServlet.processActionForm. The
ActionForm should also have a method called something like populateForm()
which the user developer could override to retrieve any values required from
sessions/databases etc. This would be called automatically when
formValidation *fails* and is probably better left to the developer to call
from Action.performAction if validation succeeds. My example would then be
along the lines of:
ActionForm {
... other stuff...
HttpServletRequest request;
void setRequest(HttpServletRequest r) {.}
void populateForm() {}
}
MyOrderActionForm extends ActionForm {
String itemId;
Object item;
// get/set item id and get/set item omitted
void populateForm() {
ItemMap map= (ItemMap) request.getSession.getAttribute("item map");
item = map.get(itemId);
}
}
and for the buyit.do action (remember, called from /buyit.do?itemid=52)
perform(.) {
MyOrderActionForm form = new MyOrderActionForm();
form.setItemId( request.getParameter("itemid") );
form.populateForm();
request.setAttribute("orderform", form);
return mapping
}
And on the view, the object bean could be got from the form for displaying.
Any thoughts?
It would be better to place this into the ActionForm class and do it
properly, but I'll wait until the feature freeze is over before trying to
submit it. In the mean time i'm going to have to derive my own classes and
override functions.

I don't know if I understand your question but would making the input
attribute of the action another action give you the opportunity to retrieve
data that the jsp form needs before the jsp is displayed? I have a form that
needs a drop down populated from the database before the form is displayed.
I can never go to the jsp form directly, I always reference the action that
gets the data needed by the jsp. The action returns a forward which forwards
to the jsp with redirect="false".

Re: help! confused over forms and errors and oooh, other stuff :-)
Hi Maya,
Yep I believe that struts has a great future. I do believe that it is the
model we should be working with. I am just worried that because of the
current limitations that we will not use it. There are whole swathes of
stuff that needs to be done, especially when it comes to
internationalisation/formatting support when it comes to the view output,
but that is not a problem. Custom tags can be built to handle what is
required (as I have done so) but the internal workings of the actionServlet
is a different matter. If that does not support what you want then you end
up having to branch away from the codeline (which I don't want to do, it's a
maintenance nightmare).
We use log4J here. Now that log4j is under the apache wing, I take it that
tomcat and struts will start to use it at some point?

RE: Template tags?
At 08:27 PM 2/20/2001 -0500, you wrote: during this process. First off, the web pages we will be creating will have a common navigation bar used across the whole web site. It would be great if we can create one HTML file called navigation.jsp which all pages use. If that's the only common element on the pages, you can do that using the JSP include tags, pulling in the common nav bar within each content page. The template tags (as we've been using them, at least) support a somewhat different model: your content pages push their specific content into common templates, which place the content into regions of the template. This allows you to have standard headers, footers, or any other common content and layout without the content pages needing to know or care what the standard layout is; it also allows you to redesign the template, potentially completely re-ordering the content presentation, without changing the content pages at all. We've introduced the template tags to both java coders and HTML authors, and all found it easy to understand and like, and quite powerful. This is what we used to do with our old custom tags. We would have one html file which contained the navigation portion (both a top and left hand navigation bar). We inserted a custom tag called "application" which would be "filled" in with a particular application when rendered. We wrote one class to render the navigation portion and created several abstract methods so that subclass can fill in the "application" and "menu" tags as needed. It looked like the following (please excuse the bad ascii art ;-) NavPageDisplayer ^ | ProfilePageDisplayer | LoginPageDisplayer | MainPageDisplayer | etc... So each NavPageDisplayer subclass would always be rendered with the navigation bar. With this design it was very easy to create a new dynamic page. I was hoping we could do something similar with the template taglib used by struts. It seems that the struts template taglibs might be the solution, unfortunately the 0.5 version of struts we downloaded does not contain these taglibs. In my experience, cvs or nightly builds have been solid for a long while, and have been quite safe for development, not only for the template tags, but for the entire library. Andy Boyko[EMAIL PROTECTED] I will download the latest source from cvs. Thank you to everyone for your help! - John
RE: Struts, WebLogic 6.0 and template tags
I am using the components add-on and I like it but it shouldn't go into the 1.0 release. It's too much code and has too much functionality to be merged without some more review which will take time.

That's an easy fix but merging the code will not be a trivial effort.

When you have a lot of nested Components, and one is faulty, it is very hard

The issue with components I was complaining about, albeit not clearly, was
that if a jsp that is part of a component instance and the jsp throws an
exception, the code surrounding the include will trap the exception and
print it to the browser. I would prefer that the exception was not caught so
that I could set up some global handler. Trapping the exception and printing
it to the browser means that the site operator won't know users are
experiencing trouble.
Below is some of the offending code from
s1.struts.taglib.component.IncludeTag.java. Fixing it would involve trapping
the exceptions and throwing a JspException. Unfortunately that has its own
problems because JspExceptions can't nest the root exception so you don't
know exactly where the error occured. At least you know that something bad
happened. I am not planning to fix this problem for the time being, I am
just planning to write the jsps so they don't fail. :

Re: Missing struts-config_1_0.dtd when not logged on
Well I'm sure this should work under Tomcat 3.2.1 (unless something in the Feb 20
build broke things). I've had this issue under other servlet engines, and a slight
enhancement was made to Struts last week as a workaround. In the web.xml, add a
parameter to the Action servlet with the name "validating" and the value "false"; and
remove the !DOCTYPE ... tag from the struts-config.xml file. This will prevent DTD
validation from being done when the struts-config.xml file is being parse.
In the case of Tomcat 3.2.1, though, I'd only use this temporarily as a workaround. I
know this has and is supposed to work on that platform.

Re: help! confused... now contains a proposal
Ned Seagoon wrote: I reckon the way to approach this is to modify ActionForm handling. I would add a field to this which holds the HttpServletRequest which gets set when the form is created/retrieved in ActionServlet.processActionForm. From: "Craig R. McClanahan" [EMAIL PROTECTED] Are you planning on keeping this reference to the HttpServletRequest object past the end of the current request? If so, you are pretty much guaranteed to have problems on any servlet container (such as Tomcat) that recycles request and response objects. The 2.3 servlet spec is also likely to clarify that it's not legal to maintain references to the request and response objects after your servlet's service() method returns. D'oh! Oh yes, of course. I was thinking of keeping the request around so that in a function like setItemId it could use the request to do a lookup for any information and set it into the form bean. Fine, I'll just change the populate() function to take the HttpServletRequest there. This pattern works, I modified ActionServlet.ProcessValidate so that if the validation fails, a class cast is attempted and populate() called on the form. This then picks up the required object from the session (via the request) and stores it in the form, ready to be displayed by the view. So what do you think? Is this worthy of being incorporated? Maybe this solution is not correct, but there is definately a need for what it is fixing... regards Ned.

It's another place where WebLogic is not compliant to the JSP 1.1 specs, and should be reported to them if it has not been yet. The "locale" attribute of the html:html tag is a boolean (true or false) property. The JSP engine is supposed to do the conversions outlined in Table 2-4 of the JSP 1.1 specification. The original spec did not make it clear that this was required on custom tag attributes, but that was resolved in an Errata published last year: http://java.sun.com/products/jsp/errata_1_1_a_042800.html See issue #7. cheers, Amar..

Re: attribute blah has no value
You are trying to use nested double quotes, which is probably confusing the
parser somewhat. Try this instead:
hi:hello foo='%= request.getParameter("users") %' /
Hope this helps.

RE: Struts, WebLogic 6.0 and template tags
I am not sure what you are looking for. The component library comes with
examples including a struts-template example that uses the component
library.
The issue with components I was complaining about, albeit not clearly, was
that if a jsp that is part of a component instance and the jsp throws an
exception, the code surrounding the include will trap the exception and
print it to the browser. I would prefer that the exception was not caught so
that I could set up some global handler. Trapping the exception and printing
it to the browser means that the site operator won't know users are
experiencing trouble.
Below is some of the offending code from
s1.struts.taglib.component.IncludeTag.java. Fixing it would involve trapping
the exceptions and throwing a JspException. Unfortunately that has its own
problems because JspExceptions can't nest the root exception so you don't
know exactly where the error occured. At least you know that something bad
happened. I am not planning to fix this problem for the time being, I am
just planning to write the jsps so they don't fail. :)

I am using the components add-on and I like it but it shouldn't go into

merged
without some more review which will take time. One problem I have noticed
is
that when a component is included the exceptions are caught which makes it
difficult to have any kind of global error handler. That's an easy fix but
merging the code will not be a trivial effort.
Besides, there is no compelling reason to add it to struts now because
there
is nothing to stop people using struts from also using the components
framework. When it is added to struts there will probably be some re-work
involved but it should be straightforward.

Ned Seagoon wrote: Hi Maya, Yep I believe that struts has a great future. I do believe that it is the model we should be working with. I am just worried that because of the current limitations that we will not use it. There are whole swathes of stuff that needs to be done, especially when it comes to internationalisation/formatting support when it comes to the view output, "Many hands make light work." Volunteers are welcome to assist :-). but that is not a problem. Custom tags can be built to handle what is required (as I have done so) but the internal workings of the actionServlet is a different matter. If that does not support what you want then you end up having to branch away from the codeline (which I don't want to do, it's a maintenance nightmare). We use log4J here. Now that log4j is under the apache wing, I take it that tomcat and struts will start to use it at some point? I have been hoping that the JSR for a standard logging API would be done fairly quickly, so that you could plug in any logging environment you wanted. I expect that LOG4J will quickly and easily conform to the new API when it's finalized. Until then, I am a little hesitant to commit to any particular logging API, because then we'd have to change it for the standard one later anyway. Regards Ned Craig McClanahan
Re: Struts, WebLogic 6.0 and template tags
Hello, Torsen, It is not an answer to your question. But I would like to use this email and ask the struts development team about compatibility template library and components library (http://www.lifl.fr/~dumoulin/components/). Components allow to define "instances" to reuse them with different parameter values. They have good examples how to use them for implementation. They do not have a "role" attribute yet. Both components and templates have a lot of common. Why not combine the best parts both of them and put under struts project before 1.0 release?

What if you changed the outter quotes to single quotes?

You should be able to pass the length as an object of type Integer,
and let the message formatting methods worry about converting it to a String:
errors.add("password", new ActionError("error.user.passwordinvalid",
new Integer(UserForm.MIN_PASSWORD_LENGTH));
The parameter values are all Objects rather than Strings.

Re: File Upload
Hi, guys, I am going to lunch. I think it's wise to use this time to just ask
before I doing a test, can anyone tell me that:
is these data, include file data, still avaiable in HttpServletRequst object?
Why, because out old EJB object extract these data from HttpServletRequst.
Thanks,
Jirong
The following is the "upload" example which enables you get these info from Form
bean.
=
public class UploadAction extends Action {
public ActionForward perform(ActionMapping mapping,
ActionFormform,
HttpServletRequest request,
HttpServletResponse
response) {
if (form instanceof UploadForm) {
UploadForm theForm = (UploadForm) form;
//retrieve the text data
String text = theForm.getTheText();
//retrieve the file representation
FormFile file = theForm.getTheFile();
//retrieve the file name
String fileName= file.getFileName();
//retrieve the content type
String contentType = file.getContentType();
//retrieve the file size
String size = (file.getFileSize() + " bytes");
String data = null;
try {
//retrieve the file data
data = new String(file.getFileData());
}
catch (FileNotFoundException fnfe) {
return null;
}
catch (IOException ioe) {
return null;
}
//place the data into the request for retrieval from display.jsp
request.setAttribute("text", text);
request.setAttribute("fileName", fileName);
request.setAttribute("contentType", contentType);
request.setAttribute("size", size);
request.setAttribute("data", data);
//destroy the temporary file created
file.destroy();
//return a forward to display.jsp
return mapping.findForward("display");
}
//this shouldn't happen in this example
return null;

Re: Struts, WebLogic 6.0 and template tags
Thanks all for you comments on Components library. Unfortunately, I have less and less time for Components. So, if there is some volunteers to improve them, let me know. I will soon put Components project on a CVS server. This will allows others people to participate ... Cedric "Deadman, Hal" wrote: I am using the components add-on and I like it but it shouldn't go into the 1.0 release. It's too much code and has too much functionality to be merged without some more review which will take time. One problem I have noticed is that when a component is included the exceptions are caught which makes it difficult to have any kind of global error handler. That's an easy fix but merging the code will not be a trivial effort. Besides, there is no compelling reason to add it to struts now because there is nothing to stop people using struts from also using the components framework. When it is added to struts there will probably be some re-work involved but it should be straightforward.

Components allow to define "instances" to reuse them with different parameter values. They have good examples how to use them for implementation. They do not have a "role" attribute yet.

Re: ActionForm.reset()
Christian Billen wrote: Hi list, Is there a way to prevent the reset() method from being called on the ActionForm when the validate option in struts-config for that mapping is set to false? Doing this would break the recommended approach for dealing with checkboxes, which rely on reset() being called to reset the corresponding booleans to false. You will want this to occur even if you are not validating, so that the bean properties correctly reflect what the user last entered. My problem is that I have an Action to prepare the data for a jsp page and another Action to process the data from that jsp. Both point to the same ActionForm class. In my prep action (/prepare.do), I configured the mapping not to validate the form, but still I see that the reset() method is being called, very annoying considering that some properties in my actionform are set to a default in the constructor (like a checkbox set to true) and that I have code in reset of the same form to clear checkboxes. Shouldn't reset be called by the controller only when validate is true? The Struts example application faces a similar situation. In the EditSubscriptionAction, it creates a new form bean (initialized to defaults in the constructor) and *replaces* the one that was created by the controller servlet (and on which reset() was called). You might consider using a similar technique. Craig McClanahan Thanks for your advise, Christian Billen
RE: taglib error when running struts1.0 on weblogic 5.1
And all the necessary *.tlds are in .../WEB-INF right? If you continue to have problems you may want to try leaving the archive expanded, and adding two entries to the WL classpath: struts.jar and the path to the .../classes directory. You also need to update WL.properties to point to the directory of the app instead of the war. I know that this is not desirable, putting struts.jar in the classpath, but the WL classpath (and classloader) is different and I have found this is needed to get things to work if you try to deploy an expanded archive. Not exactly a good answer, but it might allow you to continue with development. There are some issues with a few of the tags and WL that involve URL encoding, so if you are trying to use one of these tags you will have problems. You can see which ones these are by running the struts test app. But I think this results in a different error. -Original Message- From: Nanduri, Amarnath [SMTP:[EMAIL PROTECTED]] Sent: Wednesday, February 21, 2001 11:10 AM To: '[EMAIL PROTECTED]' Subject: RE: taglib error when running struts1.0 on weblogic 5.1 Hi Harish, I do have the struts.jar file in the web-inf/lib directory. cheers, Amar.. -Original Message- From: Dorai, Harish (c) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 21, 2001 11:08 AM To: '[EMAIL PROTECTED]' Subject: RE: taglib error when running struts1.0 on weblogic 5.1 Do you have the "struts.jar" file in the WEB-INF/lib directory of your Web application?

Re: auto reload of message resource and URL-rewrite
"Kan Leung, MK" wrote: Hi, Extracted from struts-example's walking tours: "You can even reload the configuration and message resources without restarting the container. See the end of the web.xml file for details." * My 1st question is: how to achieve auto reload of message resources? At the bottom of the struts-config.xml file for the example application, you will see an action definition: action path="/admin/reload" type="org.apache.struts.actions.ReloadAction"/ which means you can send a request to the following URL (assuming the normal *.do mapping): http://localhost:8080/struts-example/admin/reload.do and the Struts controller servlet will reload all of the configuration files and message resources (but not the Java classes -- you have to ask your servlet container to reload the app in order to accomplish that). You can use any of these standard actions in your own applications as well. * My 2nd question is about "struts-example". Everytime when I load "http://localhost/struts-documentation/", the image is never loaded successfully at during first time. I viewed the source it the IMG_SRC is "/struts-example/struts-power.gif;jsessionid=nhiizz1yq1". May I know why URL-rewrite is invoked for my browser, which cookie capability is properly enabled? The image is loaded successfully when I pressed "reload" on my browser. The string ";jsessionid*" is gone. What servlet container are you using? Some containers (such as Tomcat 3.2 running behind Apache) do not correctly deal with URL-rewritten session ids unless you modify their configuration slightly -- in this case, you have to define a "rewrite rule" in the Apache configuration file to make it work. The details are in the Tomcat FAQ-O-MATIC, which you can reach via http://jakarta.apache.org.

Small problem with TRANSACTION_TOKEN_KEY + multipart support
The transaction enforcement support in class Action assumes that the key will be returned in the request attributes. This is not the case with pages that require multipart support (for file uploads, for example). A direct work-around exists -- just use the generateToken() and saveToken() methods, handle schlepping the key in the form yourself, and write your own one-liner to compare the schlepped key with the stored one. It took me an embarrassingly long time to find this problem because of my (deserved) faith in Struts. g Maybe it should be documented, though devoting resources to fix it now is probably not necessary. -r Richard Reich http://reich.com http://calendar.yahoo.com/richard+reich

Subject: Re: Problem w/ Struts and VA for Java
Hi Tom,
I'm using VAJ 3.5.2 with Tomcat 3.2.1 with no problems at all. Here is my
setup:
Get rid of any IBM WTE stuff
Import the servlet.jar from tomcat into it's own project
Import all the struts source and resources into its own project
Create a class in a package in another project called 'TomcatRunner' (code
follows at the end of this mail)
right click on tomcat runner and set the properties
in properties set tomcat.home=c:\yourwebhome
on the class path page set the 'extra directories' path to be
c:\TomcatLocal\lib\webserver.jar;
c:\TomcatLocal\lib\ant.jar;
c:\TomcatLocal\lib\jasper.jar;
c:\TomcatLocal\lib\jaxp.jar;
c:\TomcatLocal\lib\parser.jar;
(or whatever your directories are)
And in the project path add the VAJ projects for the servlet API and struts,
plus whatever your own app project is. And that should be it, you can edit
and debug your own code and the struts source in VAJ.
Your problems will come if you try to import Tomcat into VAJ. That I have
not managed to do sucessfully!
Hope that helps!
Ned

Struts people
I had great success using VAJ to develop Struts applications a few
months ago, but recently upgraded my Tomcat to 3.2.1 and Struts to
recent releases. I lost the ability to develop and debug my Struts
application classes within VAJ.
Craig's excellently clear message of Feb. 13th (#4566) entitled
'Classpaths and the "struts.jar" file' gave, I believe, the reason.
Craig explained that containers (esp. Tomcat 3.x and 4.x) use custom
class loaders that *must* find struts.jar and application classes in the
WEB-INF

"Craig R. McClanahan" wrote: Maya Muchnik wrote: Hello, Torsen, It is not an answer to your question. But I would like to use this email and ask the struts development team about compatibility template library and components library (http://www.lifl.fr/~dumoulin/components/). Components allow to define "instances" to reuse them with different parameter values. They have good examples how to use them for implementation. They do not have a "role" attribute yet. Both components and templates have a lot of common. Why not combine the best parts both of them and put under struts project before 1.0 release? There is no end to good ideas for improvements to Struts, and the components library is one of them. However, if we kept adding new functionality we'd never have a 1.0 release, and that's not good either. This is definitely high on my personal priority list to look at for 1.1. Me too. As soon as I get my book out the door, I'll take a look at adding components to Struts. david (the Struts templates guy)
Re: validator.xml - rules for a mask
The validator uses the Jakarta Regexp regular expression package. You can find more about it here: http://jakarta.apache.org/regexp/ If you follow the link to the JavaDoc, and look at the documentation for the RE class, you'll find the specification of the syntax it works with.

Re: validator.xml - rules for a mask
Here's the link directly to the javadoc online. http://jakarta.apache.org/regexp/apidocs/org/apache/regexp/RE.html There are a lot of good tutorials on regular expressions. This package follows Perl regular expression syntax so you can read any Perl regexp tutorial you find.

RE: File Upload
Ji Rong Hu,
The file upload example you are using is old and uses the deprecated (or at
least not recommended to use) getFileData() method. The recomended method
is to use the getInputStream() method to obtain an input stream to the form
file and read it that way. I attached the newer UploadAction source file
that uses this method. You can find this in any recent build of Struts.

Subject: Re: File Upload
Hi, guys, I am going to lunch. I think it's wise to use this time to
just ask
before I doing a test, can anyone tell me that:
is these data, include file data, still avaiable in HttpServletRequst
object?
Why, because out old EJB object extract these data from
HttpServletRequst.
Thanks,
Jirong
The following is the "upload" example which enables you get these info
from Form
bean.
=
public class UploadAction extends Action {
public ActionForward perform(ActionMapping mapping,
ActionFormform,
HttpServletRequest
request,
HttpServletResponse
response) {
if (form instanceof UploadForm) {
UploadForm theForm = (UploadForm) form;
//retrieve the text data
String text = theForm.getTheText();
//retrieve the file representation
FormFile file = theForm.getTheFile();
//retrieve the file name
String fileName= file.getFileName();
//retrieve the content type
String contentType = file.getContentType();
//retrieve the file size
String size = (file.getFileSize() + " bytes");
String data = null;
try {
//retrieve the file data
data = new String(file.getFileData());
}
catch (FileNotFoundException fnfe) {
return null;
}
catch (IOException ioe) {
return null;
}
//place the data into the request for retrieval from
display.jsp
request.setAttribute("text", text);
request.setAttribute("fileName", fileName);
request.setAttribute("contentType", contentType);
request.setAttribute("size", size);
request.setAttribute("data", data);
//destroy the temporary file created
file.destroy();
//return a forward to display.jsp
return mapping.findForward("display");
}
//this shouldn't happen in this example
return null;
}
