RE: Tokens - a simple explanation wanted
The basic idea for the use of token is to deny duplicate request submissions. How do we use it? When the user goes to a form for the first time, the saveToken methods needs to be called, this will create a token in the user's session and a matching request token in the request object which will be defined as a hidden parameter on the jsp page. Once the form is submitted, we will need to check whether the request and session token match by calling isTokenValid. This will return true and we now call the saveToken method once again thereby creating a new token in the user's session. If the user now clicks on the browser's back button the hidden (request) parameter on the old jsp page will not match the new session token that has just been created. If the user decides to resubmit the old form we will call the isTokenValid method and it will return false. Struts have created the following token methods. generateToken protected java.lang.String generateToken(javax.servlet.http.HttpServletRequest request) Generate a new transaction token, to be used for enforcing a single request for a particular transaction. Parameters: request - The request we are processing isTokenValid protected boolean isTokenValid(javax.servlet.http.HttpServletRequest request) Return true if there is a transaction token stored in the user's current session, and the value submitted as a request parameter with this action matches it. Returns false under any of the following circumstances: * No session associated with this request * No transaction token saved in the session * No transaction token included as a request parameter * The included transaction token value does not match the transaction token in the user's session Parameters: request - The servlet request we are processing resetToken protected void resetToken(javax.servlet.http.HttpServletRequest request) Reset the saved transaction token in the user's session. This indicates that transactional token checking will not be needed on the next request that is submitted. Parameters: request - The servlet request we are processing saveToken protected void saveToken(javax.servlet.http.HttpServletRequest request) Save a new transaction token in the user's current session, creating a new session if necessary.

RE: How is property field used in errors.add
The property can be used if you want to display the error message next to a
specific field on the jsp page.
So after the form adds the errors, on the resulting jsp, if u have something
like
html:errors property=CG_Branch html:text blah blah.. wil make the error
to be displayed next to the html:text tag..

Subject: How is property field used in errors.add
We are using just standard validation using a validate method within the
ActionForm
There are a series of validations, which look like the following:
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (getCG_Branch() == null || getCG_Branch().length() 1) {
errors.add(CG_Branch, new
ActionError(errors.required, Contact General: Branch));
System.out.println(getCG_Branch failed.
Contact_General_LoanAction will not executed);
}
return errors;
}
The Contact General: Branch is passed as a parameter to errors:required
(which is specified in the ApplicationsResources.properties file)
{0} is required
According to the Struts documentation, the errors.add call
void add(java.lang.String property, ActionError error)
Add an error message to the set of errors for the specified
property.
So what functionality does this specified property provide??

RE: Re: Best Practices for Logging?
Just some addition to this logging discussion.
If u are using log4j , then in any case,there wil be 1 instance per class and
not per object.BEcause logger instances are named entities and they are
cached.So if u ask for the same logger again(same class name I mean), u will
retrieve same instance.New instance will not be created.I dont know how other
logger implementations used in commons logging work.So u dont add any
performance advantage by making them static.

Subject: Best Practices for Logging?
I'm wondering what is considered the best practice for logging using
commons-logging in a Struts app. My current approach is to
have a Base
class in every package that has the following:
protected Log log =
LogFactory.getLog(my.package.name);
But I've noticed that some of the Struts examples have an instance of
this in every class.
Personally I prefer the class level. This provides you with a finer grain of
control. However, I restrict it to only one per class and not one per object
public class Foo {
private static Log log = LogFactory.getLog(Foo.class);
..
}
General consensus seems to be that this is the best practice approach.
You wind up with more loggers, but they give you very fine-grained
control as Sri mentioned. You can still set a log-level for a package,
but you then also have the ability to manipulate the log-level on a per
class basis too - so you can relaly zoom-in on things.
Is this recommended, so that logging
can be done
on a class level, as well as a package level? Any thoughts/opinions
are appreciated.
It should be a static member as per what Sri shows (so you only have one
per class). Yes - it's so you can control logging on a package/class
basis.
Thanks,
Matt

Access/Manage client's file system
Sorry not to have answered earlier but I did not work Friday. By 'local' I mean the client's machine not the server. First, the server offers templates to the client. Example of JSP: Name = Toto; Type = Data; Value = 12; etc Save Load Apply Cancel If the user select the save button I would like to save data on the client's machine and the load button allows to load a file from the client's machine. We could store instances of the template on the server but it is specific to each client that's why we think that it is better to allow the client to access file system. For us server allows to store only common data. If you think it is better to save data on the server, thanks to explain. Do you understand my question better ? If I understand your reply, to do that I must use Client plugin technologies. Do you have an example ?

Lists, actions and links
Hello I've having trouble working out which is the best way of iterating though a result set , I can and have done this is several ways. 1. Imagine i have a class that querys a db and returns a result set. I pass the result set as a datastructure to my action class and all is well .. But I have to call the action to produce the list on my page. E.g. MyModelClassThatAsksTheDBForResults ListJismAction have an action listjism.do and link to this 2. or I have a bean that gets the resultset, via another class or in the bean, I instantiate the bean using the useBean jsp syntax and then iterate through using the gets defined in my bean. I don't have to have a list action, but there's something that smells about this (i'm not sure what). E.g. ListJismBean and have a normal link to listjism.jsp that uses a mix of standard jsp and struts. I know that the later is probably faster, but I'm not worried about that. I'll worry about that once my app all works (albeit slowly). An additional question is should i be only calling actions for every page or not, i read different views on this which has confused me. It seems that centralising all the links in action that can be adminstered from config.xml would only be more maintainable if and only if everything is in there.

RE: Access/Manage client's file system
Well, if you can make do with something thats rather user unfriendly you can use the standard html stuff: For the files to be saved on the users machine you could provide a link - clicking the link will allow the user to download the file which they can save on their machine. For the server to read the file you provide a file upload field and the user browses through their filesystem for the file required. Of course its a very manual process which is a lot more messy than the interface you hope for in your example and in both cases you have no control over the file names used. It is up to the user to choose where to save it, and also up to the user to select which file to send back. -Original Message- From: Heligon Sandra [mailto:[EMAIL PROTECTED]] Sent: Monday, December 09, 2002 17:17 To: '[EMAIL PROTECTED]' Cc: '[EMAIL PROTECTED]'; '[EMAIL PROTECTED]' Subject: Access/Manage client's file system Sorry not to have answered earlier but I did not work Friday.

Re: Lists, actions and links
The way I would do this would be to have a Data Access Object (DAO) class that does your database access. The method would return a collection of Value Object.

Re: Access/Manage client's file system
I don't think storing this on the client is a good approach to doing it... if you choose to do this, then you're breaking one of the Web's main advantages, which is client independency (you will most likely lock the user to a single browser that supports a specific plugin, 95% chance that it will be IE). You should really consider using the server to handle the templates. Do you have many clients accessing this application? Are the templates too big, and do you have many of these files for each user? You could even consider using a database to store templates, and read them when the user needs their data. Then you could save them in the user's session for optimal performance. There are many ways of doing it, but it all depends on how you are going to use the files. --- Heligon Sandra [EMAIL PROTECTED] wrote: Sorry not to have answered earlier but I did not work Friday.

Multiple Submit Buttons + Internationalisation
Multiple Submit Buttons + Internationalisation
I have a jsp with three submit buttons (update, delete etc..) each with a
value as loaded from the resource bundle:
input type=submit name=Submit value=bean:message key='label.update'/
In my action class i do the following to identify which button has submitted
the form:
if (Update.equalsIgnoreCase(pRequest.getParameter(Submit))) {
//Process my update
}
This works fine when viewed from a browser with an English locale, if the
locale is anything different it fails.
Its obvious why this doesn't work as i've hardcode the action class to one
locale (English).
Can someone please suggest a different approach?

You could probably compare pRequest.getParameter(Submit) against the
internationalized string, though it might be better to go a way that won't
make you dependent on those labels. You could flip it around and decide
based on the Name of the submit button. Something like:
if ( pRequest.getParameter(update_submit) != null ) {
// do an update
} else if ( pRequest.getParameter(delete_submit) != null ) {
// do a delete

RE: Re: No bean found under attribute key - any config problem?
No.U are not getting it right. U should understand the flow of struts for this. For the bean to get instantiated, it has to associated with some action. And from u r config file, it looks that u have mapped the form to /customer action.So if u call this customer action first, then in the action say mapping.findForward(success) and change the mapping for action as follows. action-mappings action path=/customer type=org.ig.shopone.web.actions.CustomerAction name=customerForm scope=request/ forward name=successpath=/yourjsp.jsp/ /action-mappings then this will work. If u are directly calling jsp, there is no way the form bean will be available. And the tag does not create any bean.It accesses the bean avaiblable already(generally created in action..) And it works without the logic tag is because in rest of u r page, u are not refering to any of bean attributes.i.e. form bean is not referred. regards, Shirish -Original Message- From: satyanarayana [mailto:[EMAIL PROTECTED]] Sent: Monday, December 09, 2002 2:13 PM To: struts-user Cc: satyanarayana Subject: Re: No bean found under attribute key - any config problem?

RE: No bean found under attribute key - any config problem?
Hi Satya, From what you've included of your JSP file, it looks like the problem is that the page has no reference to the customrForm bean by the time you go to use it. The html:form.../ tag makes this bean available, but since you are using the logic tags inside your header rather than within an html:form, this bean is not available. If the action property does in fact belong in your form bean (as opposed to being its own request attribute), then you can import the form bean with a jsp:useBean.../ tag at the top of your JSP. I don't know how well jsp:useBean and html:form play together when referencing the same bean, but give it a try with something like this: jsp:useBean id=customerForm scope=request type=org.ig.shopone.web.CustomerForm/ Just put that line at the top of your JSP and see what you get. If the action property is never part of your form, then you might want to consider making it its own request attribute, populated within the Action class, and imported with a jsp:useBean tag similar to the one above.

Betreff: Multiple Submit Buttons + Internationalisation
Multiple Submit Buttons + Internationalisation
I have a jsp with three submit buttons (update, delete etc..)
each with a
value as loaded from the resource bundle:
input type=submit name=Submit value=bean:message
key='label.update'/
In my action class i do the following to identify which
button has submitted
the form:
if (Update.equalsIgnoreCase(pRequest.getParameter(Submit))) {
//Process my update
}
This works fine when viewed from a browser with an English
locale, if the
locale is anything different it fails.
Its obvious why this doesn't work as i've hardcode the action
class to one
locale (English).
Can someone please suggest a different approach?
Cheers

RE: Multiple Submit Buttons + Internationalisation
On a related topic...does the HTTP standard specify that for a set of submit buttons with the same name, only the one that's pressed will be sent with the request? I seem to remember in earlier days that this wasn't always guaranteed, and therefore I generally make a rule to avoid it. Is my memory fuzzy and this always worked, or is this submit button functionality relying on the HTTP implementation of certain browsers, but not necessarily all of them.

query parameters
In order to understand the correct flow of Struts, i'm trying to create a simple form that has 2 fields and a Next and Previous button/link. As i click the buttons/links, i want the form fields to be filled with data from a database (1 record at a time). This appears easy enough to do - i could simply make the Next/Previous buttons/links point to a next.do or prev.do servlet which would perform some Action (which in turn would use some delegate (?) to access the database and populate the formbean) and then redirect (forward) to the particular JSP (to auto-fill the fields). (Jeez! I hope i got the above right so far). HOWEVER, what i'd *like* to be able to do is each page should be book-markable - i.e. the page should have a query string (perhaps ?id=primaryKeyinDatabase) so that the user can get to a particular record directly. It seems to me that by doing the redirect (forward) from the servlet, i would not be able to achieve this? How can i do the above? Or is this one of those cases where i *shouldn't* be using Struts?

Subject: does ActionForm support inheritance field
Hello,
Sorry to send the question again. But I didn't see the message appearing on
the mailing list for some reasons. Besides the previous message has a wrong
return email address.
I have an ActionForm, which includes a field/getter/setter of subclass. The
subclass inherits the description field/getter/setter method from its
superclass.
In my JSP page, I try to access the description. But it is complained no
getter method for subclass.description in the ActionForm.
Does anybody have any clue? Is it a limitation of Struts?
Thanks.
Denis

SV: query parameters
Example to help clarify:
You should create an action mapping that looks something like:
action type=yourpack.ShowRecordAction path=/viewrecord
forward name=success path=/view.jsp /
forward name=fail path=/error.jsp/
/action
ShowRecordAction looks something like:
package yourpack.ShowRecordAction;
//imports.
public class ShowRecordAction extends org.apache.struts.action.Action {
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// Use the request parameter (for example id) that you provide to
// do the lookup and put the record (or whatever object that you
// want to print) in some scope
request.setAttribute(record, yourRecordObject);
// You can also find out the next and previous record ids here and
put them
// in some scope to
// if all is ok you return mapping.findForward(success)
// if something is not ok you can return
mapping.findForward(fail);
return yourActionForward;
}
}
You are then free to use the record object in your jsp according to your
needs, just retrieve it from whatever scope you put it in.
To invoke the action you do:
http://your.url.com/do/viewrecord?id=someIdToData
(or http://your.url.com/viewrecord.do?id=someIdToData depending on the
mapping in web.xml)
Which in turns forwards to the jsp for display.
This should work but I'm just a novice in Struts so...
If I'm wrong I hope somebody corrects me

Well, forget Struts for the moment. Let's just work with JSPs and servlets
for a moment.
I'd imagine that you'd probably want a URL scheme as you suggest, i.e.
something like
http://your.host/yourServletContext/yourServlet/showRecord?recordid=5.
Then you'd have a servlet set up in your web application (rooted at the
yourServletContext servlet context path) to receive URLs ending, let's
say, in /yourServlet/*. When that servlet received any request, it would
then do something like this:
final String parameterValue = request.getParameter(recordid);

requestDispatcher.forward(...);
}
Your JSP would then reach into its request, either in a scriptlet or via the
standard bean mechanisms, and would show the record data using expression
tags.
Once you get it working (or at least once you go through the thought
exercise of how this would work) without Struts components, then it's easier
to see how Struts fits into the big picture.

html:options encoded property
Hi! I wrote a JSP page with the following lines : ... html:select property=selectedProxies size=10 multiple=true html:options collection=proxies property=url labelProperty=name/ /html:select ... where name and url are the String attributes of a bean named Proxy. This code displays a box, with a list of names. When I select a name, this returns the corresponding url. The problem is that the url is written with escaped characters, BUT displayed with unescaped characters. For example, the bean Proxy has the following url linked with the name something : http://myhome/helloamp;action=quot;doSomethingquot;;. But, the resulting html page looks like this : ... select name=selectedProxies multiple=multiple size=10 option value=http://myhome/helloaction=doSomething;something/option ... The quot; character is translated. As a result the option value becomes http://helloaction=; : it stops at the first : character and doesn't take the whole url! doSomething is forgotten... I looked for attributes like filter for the html:options tag, but I didn't succeed...Has someone an idea to help me! Thank you!

RE: query parameters
Marcus -
Well, i certainly hope you are not wrong, cos this was the path i was going
down. :) The only thing is when i use
http://your.url.com/do/viewrecord?id=someIdToData (or
http://your.url.com/viewrecord.do?id=someIdToData), it will then forward to
http://your.url.com/view.jsp with the appropriate data filled in. So when
the user looks at the URL, they will cut-and-paste
http://your.url.com/view.jsp which will most likely display a blank form (at
a later time). So i still haven't solved the original problem.

Example to help clarify:
You should create an action mapping that looks something like:
action type=yourpack.ShowRecordAction path=/viewrecord
forward name=success path=/view.jsp /
forward name=fail path=/error.jsp/
/action
ShowRecordAction looks something like:
package yourpack.ShowRecordAction;
//imports.
public class ShowRecordAction extends org.apache.struts.action.Action {
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// Use the request parameter (for example id) that you provide to
// do the lookup and put the record (or whatever object that you
// want to print) in some scope
request.setAttribute(record, yourRecordObject);
// You can also find out the next and previous record ids here and
put them
// in some scope to
// if all is ok you return mapping.findForward(success)
// if something is not ok you can return
mapping.findForward(fail);
return yourActionForward;
}
}
You are then free to use the record object in your jsp according to your
needs, just retrieve it from whatever scope you put it in.
To invoke the action you do:
http://your.url.com/do/viewrecord?id=someIdToData
(or http://your.url.com/viewrecord.do?id=someIdToData depending on the
mapping in web.xml)
Which in turns forwards to the jsp for display.
This should work but I'm just a novice in Struts so...
If I'm wrong I hope somebody corrects me

RE: query parameters
Laird -
Yeap! Thanks for your patience in helping me. I understand your (pure)
JSP+Servlet example. However, even in that example, when the
requestDispatcher.forward(...) is executed, doesn't the browser display the
URL that the requestDispatcher forwarded to (which would be the JSP page)?
So when the user views the page, they don't know that they had used
http://your.host/yourServletContext/yourServlet/showRecord?recordid=5 to
access this page, all they see is the *final* URL which is the JSP page that
the servlet (showRecord) forwarded to.
For example, in any forums, you can view a particular message using
http://your.host/viewthread.jsp?messageid=123124 - does this mean that that
forums application is *not* using MVC? and is using only JSP (with all logic
embedded)?
Thanks.

Thanks for the response Laird. That's exactly the way i
understood it so
your response helped validate my understanding (and yes,
that's precisely
why i'm trying to use Struts - to separate business logic
from presentation
logic). However, after (2) takes place, i would have arrived
at the JSP
page displaying the particular database record. So how can a user
bookmark the page to come back directly to this particular
record? I
guess if the URL had the servlet (+ query parameters), the user could
bookmark that. But since there is a forward involved,
wouldn't the URL
(with the servlet+query parameters) be lost?
What am i missing here? :(
Well, forget Struts for the moment. Let's just work with JSPs
and servlets
for a moment.
I'd imagine that you'd probably want a URL scheme as you suggest, i.e.
something like
http://your.host/yourServletContext/yourServlet/showRecord?recordid=5.
Then you'd have a servlet set up in your web application (rooted at the
yourServletContext servlet context path) to receive URLs ending, let's
say, in /yourServlet/*. When that servlet received any
request, it would
then do something like this:
final String parameterValue = request.getParameter(recordid);
if (parameterValue != null) {
// ...try to parse it as an integer...
// ...load up the database content based off of the record id...
request.setAttribute(dbContent, databaseContent);
// ...get a RequestDispatcher...
// Forward to the appropriate JSP page.
requestDispatcher.forward(...);
}
Your JSP would then reach into its request, either in a scriptlet
or via the
standard bean mechanisms, and would show the record data using expression
tags.
Once you get it working (or at least once you go through the thought

If nothing else, you could have a web app that zips up the files and sends them as one.

Re: Help needed for a struts beginner!
The point of struts in great part is to allow you to make the HTML page (response I assume you mean) simpler, not more complex. If it is going to become more complex, don't use Struts. Struts is an application FRAMEWORK that takes functionality off the page. But, if you are using fairly simple HTML you must mean fairly static pages. The pages you use are not particularly significant in the bottom line reason for Struts, even if Struts does have taglibs that are available. You might stop and think about what Struts is and what you want to do. The JSP thing is completely separate from Struts, although certainly consistent with it. You could use Struts and Velocity.

We are using Big IP 2000 application switches controller running config 4.2 PTF7. Basically, the problem is when HTTPS session is initiated (by requesting /abc/login.do servlet and it works fine), but the links or redirects within the page is sending the session back to an HTTP none secure session.

Pluggable Validation Not Being called, any ideas?
I'm using Struts 1.1B2, and have tried to create a pluggable validator
similar to the example on Davids site.
In my validation-rules.xml I have -
validator name=twofields
classname=us.ut.state.dced.filmrg.StrutsValidator
method=validateTwoFieldsEqual
msg=errors.twofieldsequal/
Then in my validation.xml, I have -
field property=password depends=required,twofields
arg0 key=candidateForm.password.displayname/
var
var-namesecondProperty/var-name
var-valueconfirmPassword/var-value
/var
/field
When I run the application, the validation function is never called! (I
put system.out.println in it, and they are not executed.) The function
is -
public static boolean validateTwoFieldsEqual(java.lang.Object bean,
org.apache.commons.validator.ValidatorAction va,
org.apache.commons.validator.Field
field,
ActionErrors errors,
javax.servlet.http.HttpServletRequest request)
{
System.out.println(In Here!);
String value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
String sProperty2 = field.getVarValue(secondProperty);
String value2 = ValidatorUtil.getValueAsString(bean,
sProperty2);
if (!GenericValidator.isBlankOrNull(value)) {
try {
if (!value.equals(value2)) {
errors.add(field.getKey(),
StrutsValidatorUtil.getActionError(request, va, field));
return false;
}
} catch (Exception e) {
errors.add(field.getKey(),
StrutsValidatorUtil.getActionError(request, va, field));
return false;
}
}
return true;
}
Any ideas how to get the validation function called? Do I need to
register it somewhere to get it to work?
Thanks,
Ryan

Design Question regarding navigation menu
Design question regarding navigation menu. (I am using tiles) Suppose I have a navigation menu with several choices/sections, I would like to highlight the choice/section the user is currently in. Example: choice A, choice B, choice C Which is the proper approach? Create a separate menu with each choice highlighted and then have each of my tile-definitions override to the correct one. OR Create one menu header and have it make the decision as to which menu choice to highlight based on some value (value would be set/altered by an Action) OR Create one menu header that makes a decision as to which menu choice to highlight based on the URL. I am leaning towards choice two. but I am not sure what the proper way is. Any suggestions/Examples would be great. Thank you Mark

Do you have cvs installed on your local box? Go to a shell prompt and type cvs --version. If it reports the version of the Concurrent Versions System, then you should be able to type that entire command line at your prompt. If you don't get that output, then you should install a version of cvs appropriate for your platform. -Original Message- From: Hohlen, John [mailto:[EMAIL PROTECTED]] Sent: Monday, December 09, 2002 9:49 AM To: 'Struts Users Mailing List' Subject: RE: Help!

At 10:49 AM 12/9/2002 +0100, you wrote: Just some addition to this logging discussion. If u are using log4j , then in any case,there wil be 1 instance per class and not per object.BEcause logger instances are named entities and they are cached.So if u ask for the same logger again(same class name I mean), u will retrieve same instance.New instance will not be created.I dont know how other logger implementations used in commons logging work.So u dont add any performance advantage by making them static. Hi Shirish and all, Actually, I have to disagree here. Yes it is true that the Log4j Log manager only holds one instance of the logger class, but I've done some profiling and found that Logger.getLogger(String) can take significantly more CPU cycles than just referring to your static instance. In particular, under a Tag library for Tomcat 4.0.X [where tags are not reused], this was resulting in significant overhead. [IIRC about 10-15% of the CPU time.] Of course, using static variables can cause class reloading problems.. so it is kind of a six of one, half-dozen of the other situation. What you end up doing in the long run is your choice... but people do need to know that constructing logs DOES take CPU time. -Mike -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Lists, actions and links
Can i just check my understanding... I'd get my result set as one would expect do i feed it to an action and have a listmystuff action or use a bean and instansiate the bean in the jsp, no action just a normal link? The more I think about it the first option appears the puppy, no useBean in the jsp (i'm the only dev here with jsp experience) and can be managed from the config.xml. The data connectivity stuff appears a separate issue , this list could come from anywhere.

Imagine i have a class that querys a db and returns a result set. I pass the result set as a datastructure to my action class and all is well .. But I have to call the action to produce the list on my page. E.g. MyModelClassThatAsksTheDBForResults ListJismAction have an action listjism.do and link to this 2. or I have a bean that gets the resultset, via another class or in the bean, I instantiate the bean using the useBean jsp syntax and then iterate through using the gets defined in my bean. I don't have to have a list action, but there's something that smells about this (i'm not sure what). E.g. ListJismBean and have a normal link to listjism.jsp that uses a mix of standard jsp and struts. I know that the later is probably faster, but I'm not worried about that. I'll worry about that once my app all works (albeit slowly). An additional question is should i be only calling actions for every page or not, i read different views on this which has confused me. It seems that centralising all the links in action that can be adminstered from config.xml would only be more maintainable if and only if everything is in there.

Re: Access/Manage client's file system
Micael who responded to this message says he's working on something similar. To be honest I don't know any nice, cross browser way of doing this. I'd have thought the money you save on disk space would swallowed up by extra development time. However if I had to do this i'd be reading stuff about soap and/or similar stuff. The filesystem couild be controled by and application that you distribute to recienve soap envelopes and run various file system operations. I believe flash is capable of this (i'd be interested to know). Server sends soap envelope to flash movie flash unwraps envelope and runs commands based on contents. The big quest for me remains can you do file system stuff from a flash movie? My concern would be how many work arounds you'd have to do for flash because those crazy macromedia kids may have been on the crack again. A java applet could also be used, but i believe these days more people have flash than java plugins. Also do the directories remain on the local machine after the operations? Or are they created and removed each time the user wants to do his/her stuff? T Things i'd do in your shoes.. Make or find a flash movie that reads and writes soap, make or find a flash movie that performs file system operations. Get my hands on the jakarta soap tags that should help you work out what you want you java classes to do.

RE: How to switch debug off?
Look in web.xml under the init-params for struts. There is a debug level. It is described in the manual. Edgar -Original Message- From: Zsolt Koppany [mailto:[EMAIL PROTECTED]] Sent: Monday, December 09, 2002 3:45 PM To: 'Struts Users Mailing List' Subject: How to switch debug off? After I start tomcat with struts, I see a lot of log messages. How can I switch that off? I mean messages such as: 2002-12-09 21:41:55,536 DEBUG digester.Digester.sax - startElement(,display-name,display-name) [main] 2002-12-09 21:41:55,537 DEBUG commons.digester.Digester - Pushing body text '' [main] 2002-12-09 21:41:55,538 DEBUG commons.digester.Digester - New match='web-app/display-name' [main] 2002-12-09 21:41:55,539 DEBUG commons.digester.Digester - No rules found matching 'web-app/display-name'.

Problem with plug-in tag for tiles in struts-config.xml. Wrong version of struts-config_1_X.dtd ??
Hello, When i query a page for the first time since the server started, i got two errors : 9-Dec-2002 1:44:29 PM org.apache.commons.digester.Digester error SEVERE: Parse Error at line 60 column 60: Element type plug-in must be declared. ... and ... 9-Dec-2002 1:44:29 PM org.apache.commons.digester.Digester error SEVERE: Parse Error at line 66 column 17: The content of element type struts-config must match (data-sources?,form- beans?,global-forwards?,action-mappings?). It seems that the struts-config is not linking to the appropriate struts-config_1_X.dtd file. I looked in the struts-config_1_1.dtd file (which i specified in the struts-config.xml header) and it tells i can set a plug-in tag for the struts-config tag of the struts-config.xml, so the file should be ok. There is the header of my struts-config.xml file : !DOCTYPE struts-config PUBLIC -//Apache Software Foundation//DTD Struts Configuration 1.0//EN http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd; The plug-in tag : plug-in className=org.apache.struts.tiles.TilesPlugin set-property property=definitions-config value=/WEB-INF/tiles-defs.xml / set-property property=definitions-parser-validate value=true / set-property property=moduleAware value=true / /plug-in Do you have any clue ? Can you see anything wrong ?? Is there an order for specifying the plug-in tag in struts-config.xml ?? Thanks for your help !
