In my mind, the purpose of these validations is to improve the quality of the user interface -- in this case, by catching errors that can be caught inside the page (such as required fields and invalid number formats) without wasting the time needed to submit the form and get the errors back. However, it is important to understand that you should *ALWAYS* perform these validations again on the server side. Consider the following cases: * The client turns off JavaScript * The client does not support JavaScript * The user is actually typing a URL (with request parameters) directly into the location line of the browser. Basically, never trust the client to do any validations. Craig McClanahan

Re: uploading file requires immediate serialization location?
Sorry, I should have said If the bean goes away, then so does the only reference you'll get to the file that holds the uploaded data. The FormFile object, which contains the relevant information, will go away when the bean goes away (unless you have another reference to it, of course). The FormFile does not contain the actual uploaded data, just the name of the file it was saved in. -- Martin Cooper - Original Message - From: Jonathan Asbell [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, June 10, 2001 11:16 PM Subject: Re: uploading file requires immediate serialization location?

String parameters are not written to a file. Only the bodies of file upload parts are written to disk, and each one to a separate file. The files are written as the input stream (i.e. the request) is processed. Let's say your form has two fields, a textarea called 'myText' and a file input called 'myFile'. After you submit it, and Struts has populated your form bean, you will have: 1) The text from the textarea field is stored in the bean's 'myText' property as a String. 2) The uploaded data is stored in a temporary file somewhere on disk. 3) The 'myFile' property on your bean, which has type FormFile, contains information about the uploaded data (e.g. file name, content type, etc.). The bean is in either request or session scope, as you defined it in your struts-config.xml file. If the bean goes away, then so does the file that holds the uploaded data.

Yes, I think you've got it. Just to be clear, though, when you say we need to examine the sections in the header ..., the we here is Struts - you don't need to do anything in your application. Struts makes getParameter() et all work for multipart requests as well as regular requests. What you are seeing in the packages you've looked at is the parsing of a MIME part. The fields in a multipart/form-data request each conform to the specification for a MIME part, and they are separated by a boundary, which is a line containing a pattern defined in a header at the top of the request. Each MIME part consists of a sequence of MIME headers, followed by a blank line, followed by the data for that MIME part, known as the body. A MIME header takes the form header-name: value - for example, Content-type: text/plain. The body is just a bunch of data that conforms to the statements made about it in the headers. Every field in a multipart request is encoded this way. So where a regular query using GET might contain a query string like this: ...author=Martin... a multipart request would represent the same query parameter like this: -0123456789-- Content-disposition: form-data; name=author Martin -0123456789-- For a file upload, the difference is only that the Content-disposition header will include a file name, and the data can be binary if necessary. When a multipart handler processes a request, it is reading the data from an

RE: Where should I use .do and where .jsp for the same file
Hi Eda, This all depends on your web.xml and your struts config. The do extension is the default used by struts and configured in your web.xml to invoke the action servlet. This will then work out which action bean to invoke. So if your want to run an action bean directly you would invoke .do in your form action or link. If you need to render some information, collect user input then do something you would include the name of a form bean in your form tag. If you don't wish to collect data, just render it you would use a .jsp extension to simply forward to a jsp (although I always recommend the use of a global forward). Hope this helps, Jon. -Original Message- From: Eda Srinivasareddy Eda [mailto:[EMAIL PROTECTED]] Sent: 11 June 2001 08:40 To: [EMAIL PROTECTED] Subject: Where should I use .do and where .jsp for the same file Hi Here is a small doubt.

Hi here! Being somewhat new to struts in general and in combination with Websphere Application Server (WAS) in particular I have the following questions for you: Is it correct that only the struts-1.0-b1 distribution will work with WAS? I have deployed struts-example.war and converted it to my own application. Everything works fine except that it can't find my ApplicationResource.properties file. Searching this forum I can see that people emphasize that struts.jar should *not* be in the web apps classpath but if I try to put any other place I get the error: Application unavailable for service. Also, people suggest that it should be in the lib directory but I can find no lib directory using the struts-1.0-b1 distribution. Checking the web.xml file(s) I can see that the path for the ApplicationResources.properties is correct. Nevertheless, I get the error: Missing key for message index.title Why the flaming heck can't it find the friggin file? brgds, S.

Subject: Re: Exception handling in the ActionServlet
On Sat, 9 Jun 2001 [EMAIL PROTECTED] wrote:
Hi,
I would like to catch all of our project specific
exceptions in one place (as a
last resort, if nobody else catches them earlier on) and
handle them in a
generic way. The obvious way to do this, I think, is by overriding
processActionPerform in our own ProjectActionServlet and catch
ProjectException's (superclass for all our own
exceptions) there. But the
Action.perform method only throws IOException
ServletException, so either all
our own exceptions will have to inherit from either of
those two classes (can't
be the right thing to do), or I will have to change the
Action.perform
definition to also throw our ProjectException's (doesn't
seem right either,
I'd prefer not to have to alter any struts code)?
What should I do?
How about having the base class for you project exceptions be
a subclass
of ServletException? That way, you can throw it if you really want
to. Then you could declare an error-page element in your
web.xml file
to define common handling (if you don't the default will be
an ugly stack
trace on most containers).
Alternatively, if you have a project exception in your Action.perform
method, you could just wrap it up in a ServletException and throw that. E.g;
try {
.
} catch (ProjectException e) {
throw new ServletException(Some text, e);
}
Then in your subclassed processActionPerform method you get at your original
exception by calling the getRootCause() method of ServletException. This
avoids having to base your exceptions on any particular subclass.
This actually brings me to another problem that doesn't
have anything to do
with struts, but is more a general Java question. Anyway,
maybe somebody here
has an elegant solution to it:
Assume the problem above is solved and furthermore that
some of the project
specific exceptions have to inherit from other existing
exception classes (e.g.
ServletException, IOException, etc.). Since we don't have
multiple inheritance,
I can't have a ProjectException that is a superclass to
all my own
exceptions. I still want to catch all our own exceptions
(but no others) in one
place. My first though was of course to define a
ProjectException interface
and let all our own exceptions implement this interface,
thus being able only
to catch ProjectException's. But Throwable is not an
interface (why not?
What's the idea behind this design?) that
ProjectException could inherit from
and thus this approach doesn't work, as the try{}catch(){}
statement expects a
Throwable object as parameter
(try{}catch(ProjectException e){} doesn't
compile).
Well, as a kind of a hack I then thought I'll catch all
exceptions, check if it
is a project specific one
(ProjectException.class.isInstance(anException)),
and if not throw it again, but that can't be right, because
the method where
this happens then will have to be declared to throw
Exception (to generic).
I'll appreciate any help, thanks in advance and the best
satisfactory answer
wins a free beer in Zurich ;-)
I'd investigate extending ServletException for your
application exception
classes.
Another off-the-wall idea would be to extend RuntimeException
instead --
you can throw such an exception without it being listed in the
throws clause. This is how things like IllegalArgumentException and
NullPointerException work.

I want to change the positions of the components like label, textfields, combo boxes and their foreground and background colors. If I had not used struts, then I would have changed the UI in Dreamweaver which is very fast and quick. But now the jsp content is in html custom library tags of Struts. How can I change the UI in a fast and efficient way without going to the code of each and every jsp. Any ideas ??? Thanks Satish

RE: User management?
Hi, You seem to facing the same problem that I am. I'm using tomcat to do form based auth. This way I can take advantage of container security features and use the struts role based templating. I invoke the form based auth by invoking an action class within a secured area. This way the user logs in then I collect user data/preferences etc from my db. There doesn't appear to be anything in struts that can help. Does anyone have a better way, i.e. extending tomcat login class, JAAS etc. What I'm really after is a mechanism that will work with all containers.

This works with most containers, but the setup mechanism will be different. What container are you using? I use tomcat. You may still wish to create a user object based on info looked up, you would have to code this and place it in a session.

Hacking HTML forms
Hello, I have created a javascript widget which lets users move options from one multi-select to another as input to a search. For example they can select one or many hardcoded options in an allowed select box and then click on an arrow to move the selected options into the selected-for-this-search select box. Just before the form is submitted, I also select all the options in all the selected-for-this-search boxes so that they are submitted. My question is, can Struts support this? From the messages on this list it seems like multi-select box values need to be kept in an Array but I think mine need to be in a HashMap thanks, matt.
Session handling with wml
I'm trying to get struts working with wml. Everything works fine beside the fact, that struts always thinks it is able to place a cookie at the browser (Nokia 6210). This seems not to be working, as nothing keeps stored in session. I can't reproduce this error with the blueprint from Nokia Toolkit, even if cookies are deactivated. Manual URL-encoding has no effect, as the session-id is never added to url if a cookie was set... Anybody solved similar problem? Thanx,Maik.
Re: more template:include/ questions
Hi, I think that inserting Components or Templates using html:xxx within html:form/html:form should work. For this to be possible, html:XXX tags should use request context rather than page context to store/pass bean.

RE: User management?
Hi Tom, Struts provides the template tag, one of the options for this tag is 'role'. This uses request.isUserInRole (). User roles are setup by the containers security mechanism. I haven't found a way to programmatically set user roles. So if you want to use the 'role' option of the struts template tag you have to use container based security. See http://jakarta.apache.org/struts/api/org/apache/struts/taglib/template/packa ge-summary.html#package_description and http://jakarta.apache.org/struts/struts-template.html for further details.

Here, I do the postprocessing. In this, I update the beans (application state) using submitted form object. 4. Then I forward request to the Action object corresponding to the 'toPage'. 5. Here I do the preprocessing, in which I update the formBean corresponding to toPage using the business beans (application state) - this is like pre-population that you are referring to. 6. Now, I pass the control to the toPage.jsp. This uses the formObject pre-populated in earlier step. Hope this helps.

Re: Dynamic action mapping
Hi, I am looking for a way to invoke different Actions from one form depending on the button clicked by the user. Is there a simple way of configuring Struts to do this? not a very simple way. But you can write a dispatcher action that forwards to different actions depending on a request parameter.

Re: Pre populate
Many times pre-processing and post-processing are related, and it can be convenient to handle both in the same Action class. A good way to implement this is to have a seperate Action Mapping for each task (pre-process and post-process). Both mappings would point to the same Action but use different (virtual) paths. Like say /account/setup/pre and /account/setup/post . These may both use the same Action class, which could be package/account/setup.java . The Struts mappings accept an extra parameter property that you can easily test in the Action to see which mapping has been chosen. Your action can then process each task differently, and even go to separate locations if successfuly. By managing this all in the struts-config.xml, you gain a lot of flexbility. In struts-config: action path=/account/setup/pre type=package.account.Setup.java name=setupForm scope=request validate=false input=/WEB-INF/jsp/account/setup/Form.jsp parameter=pre forward name=success path=/WEB-INF/jsp/account/setup/Form.jsp/ /action action path=/account/setup/post type=package.account.Setup.java name=setupForm scope=request validate=true input=/WEB-INF/jsp/setup/Form.jsp parameter=post forward name=success path=/WEB-INF/jsp/account/setup/View.jsp/ /action In your Action: String task = mapping.getParameter(); // handle task for pre or task for post // ... // ... return (mapping.findForward(success)); -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/ Kiet Nguyen wrote: I need to pre-populate my form and do some business processes prior to load a page.

Anybody solved similar problem? Thanx,Maik. In most servlet containers, you can turn off the use of cookies for session maintenance -- check the docs for your container on how. For URL rewriting to work, you need to remember the following: * You must URL-rewrite (i.e. call response.encodeURL()) every single hyperlink in the application. With Struts, the html:form and html:link tags do this for you automatically. * You must ensure that a session is created before the response is committed back to the client. In general, that means be sure that you call request.getSession() -- or call a JSP page -- before the first buffer-full of output has been committed. Craig

Help with define tag

properties I want to display. I'm trying to use the define tag to get a

Re: Help with define tag
Is your getter method really as you posted it? That just returns the
parameter it is passed. It should be this:
public AddressInfo getHomeAddress()
{

}
Note the absence of the parameter. The rest looks fine, although I would
advocate making the homeAddress member private instead of public.

String parameters are not written to a file. Only the bodies of file upload parts are written to disk, and each one to a separate file. The files are written as the input stream (i.e. the request) is processed. Let's say your form has two fields, a textarea called 'myText' and a file input called 'myFile'. After you submit it, and Struts has populated your form bean, you will have: 1) The text from the textarea field is stored in the bean's 'myText' property as a String. 2) The uploaded data is stored in a temporary file somewhere on disk. 3) The 'myFile' property on your bean, which has type FormFile, contains information about the uploaded data (e.g. file name, content type, etc.). The bean is in either request or session scope, as you defined it in your struts-config.xml file. If the bean goes away, then so does the file that holds the uploaded data.

The fields in a multipart/form-data request each conform to the specification for a MIME part, and they are separated by a boundary, which is a line containing a pattern defined in a header at the top of the request. Each MIME part consists of a sequence of MIME headers, followed by a blank line, followed by the data for that MIME part, known as the body. A MIME header takes the form header-name: value - for example, Content-type: text/plain. The body is just a bunch of data that conforms to the statements made about it in the headers. Every field in a multipart request is encoded this way. So where a regular query using GET might contain a query string like this: ...author=Martin... a multipart request would represent the same query parameter like this: -0123456789-- Content-disposition: form-data; name=author Martin -0123456789-- For a file upload, the difference is only that the Content-disposition header will include a file name, and the data can be binary if necessary. When a multipart handler processes a request, it is reading the data from an input stream provided by the container. Typically, for regular query parameters, it will store the value in a hash table. For file parameters, it will store the data in a file and retain information about that file. The Struts implementation uses the FormFile interface to provide access to that information. A multipart implementation could do whatever it wanted to with the data provided from a file upload. Although the Content-disposition header may specify a file name, there is no requirement to store that data as a file. One implementation that would make sense would be to define a size threshold, and store uploaded objects below that size in memory, while writing larger ones to disk. Regarding form beans and binary data, there is no reason why a field in a form bean cannot be a byte array. However, by itself that is not very useful, hence the FormFile interface. If you'll notice, that interface does in fact have a getFileData() method, which will give you the uploaded data as a byte array. In the current implementation, what that actually does is load the contents of the file into memory and hand you back that memory. And there you have binary data in a form field. Hope this helps. -- Martin Cooper - Original Message - From: Jonathan Asbell [EMAIL

String parameters are not written to a file. Only the bodies of file upload parts are written to disk, and each one to a separate file.

ActionForms for read-only data??
I have a Struts theory question on use of action forms versus java beans for read-only data. We have extended workflow on our website such that the same form can look a bit different depending on where you are in the workflow. For example, the quote request will have limit and retention fields in the business request section. Once you get to quote, those fields are read-only and there's an additional quote amount field. When the client requests binder, all those fields are read-only and there is a checkbox. Once bound, everything is read-only. There is some disagreement on the team as to how to handle this case. We will obviously have four JSPs, one for each of these presentations. The question is the data mapping to beans. Half of the team feels that to use Struts in its purest sense, we need to have java beans that represent the read-only data, and action forms to represent the editable data. That would mean four action forms, one for each JSP. The other half of the team wants to re-use the same action form for all four cases, bean:define it in the session, and use bean:write to print out the data if read-only. The major advantage is simplicity - we have one bean that represents all of the data - there is no need to understand what part of the workflow we are in when translating the data from the data model to the presentation layer beans. It is also easier to understand for an HTML programmer or developer that the same bean is used regardless of whether it is a bean:write or any of the html tags. We certainly don't want to end up in a position where we have broken the framework and hurt our extensibility in future releases. The first scenario would seem to follow the framework more closely, but in this special case, is it a problem to deviate and use the ActionForm for what it is - a bean?

multiple mapping problems
Hello, I've been trying to figure out why this is happening and have had no luck, so I figured maybe someone here could help. I don't know if this is a bug, or if I just don't understand the correct application framework, etc. I have two servlets defined in the web.xml file (servlet1 and servlet1) of class types servletclass1 and servletclass2. Each one has the init-param 'config' set to the same 'stuts-config.xml'. Each servlet has a different mapping (*.do1, *.do2). In the stuts-config.xml file I have two action paths defined (/path1 and /path2) with types actionclass1 and actionclass2. The requests are only for path1.do1 and path2.do2, never path1.do2. When I load this, both mappings get mapped to both servlets: Call package.ServletClass1.addServletMapping(servlet1/java.lang.String,*.do 1/java.lang.String) Call package.ServletClass1.addServletMapping(servlet2/java.lang.String,*.do 2/java.lang.String) then later on Call package.ServletClass2.addServletMapping(servlet1/java.lang.String,*.do 1/java.lang.String) Call package.ServletClass2.addServletMapping(servlet2/java.lang.String,*.do 2/java.lang.String) Any ideas?

Re: ActionForms for read-only data??
The important thing about ActionForm beans is that they are intended as adapters between HTML forms and the rest of the application. If the property is being used within a HTML form, then it is a valid use of an ActionForm bean, regardless of whether the property is hidden or immutable. It is not expected that there will be a 1:1 relationship between a HTML form and an ActionForm bean. Some ActionForm beans may be used on several forms, and several forms may use the same ActionForm bean. In general, most people would design ActionForm beans to represent a logical view (in the SQL sense) within the application. If the data is being accessed by the same SQL query, then it would make sense to put it all on the same ActionForm bean, regardless of whether it is exposed. The only thing to watch for is Strut's calling reset() as part of the validation. If a property is not present in the form, then it will be reset, and your validation has to cope with that. One caveat: ActionForms are not meant to be a panacea for the presentation layer. There are often other JavaBeans in play on this layer, with ActionForms being specialized for use with HTML forms. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/ [EMAIL PROTECTED] wrote: I have a Struts theory question on use of action forms versus java beans for read-only data.

Javascript implementation of html:rewrite ?
I ran into an interesting problem:
I need the ability to rewrite the url, with the encoded session information,
dynamically, after the page has already been loaded by the browser client.
I am opening a new browser window for doing searches, some of the fields on
my first page need to be passed along to this secondary page.
If I didn't need to pass parameters from my form onto the new window I could
just use the rewrite tag.
Like this:
window.open ('html:rewrite
page=/findRequestedFacility.do/',
'provider', 'scrollbars=yes,width=640,height=480,status=yes');
However, my url needs to look something like this:
//Grab a parameter off my form...
var lUrl = /findRequestedFacility.do?FacilityId=' +
form.facilityId.value + ';
//Rewrite the URL...Need Javascript function to do this.
lUrl = rewriteUrl(lUrl);
//Open the thing.
window.open (lUrl, 'provider',
'scrollbars=yes,width=640,height=480,status=yes');
Has anybody written a javascript function to do this?

Interfaces in Struts
I wanted to share my approach because it seems successful for what we're
doing. I can't imagine we're the only ones doing it, but just in case we
are, I wanted to share. I'd also like to hear any and all comments and
criticisms.
We use Struts to present database tables to the user so that we may collect
information from them, validate it, and process it. Nothing new here.
In order to make sure we only have to design these beans once, I used
interfaces from the beginning. So a profile starts out as something like
this:
/*
* Profile.java
*/
package com.trams.project ;
public interface Profile {
int proifleno = 0 ;
String firstname = null ;
String lastname = null ;
.
.
.
int getProfileno ( ) ;
void setProfileno ( int profileno ) ;
String getFirstname ( ) ;
void setFirstname( String firstname ) ;
void setLastname ( String lastname ) ;
String getLastname ( ) ;
.
.
.
}
// end of Profile.java
Once I have the interface, I also write the class that uses it. In this
case, a database interactivity class that constructs SQL statements in order
to process the data presented to it:
/*
* ProfileDBM.java
*/
package com.trams.project ;
public class ProfileDBM extends DatabaseManager {
Profile table = null ;
public void setTable ( Object table ) { this.table = (Profile) table
; }
public void create ( ) {
.
.
.
}
public void retrieve ( ) {
.
.
.
table.setProfileno(rs.getInt(PROFILENO)) ;
table.setFirstname(rs.getString(FIRSTNAME)) ;
table.setLastname(rs.getString(LASTNAME)) ;
.
.
.
}
public void update ( ) {
.
.
.
}
public void delete ( ) {
.
.
.
}
}
At this point you can see (or have to trust) that nothing uses Struts,
Servlets, or anything other than basic packages. The above code could be
used to populate any object with Profile information, be it a command line
utility, AWT object, or even a Struts ActionForm.
I then implement my Profile into an ActionForm:
/*
* ProfileForm.java
*/
package com.trams.project ;
public final class ProfileForm extends ActionForm implements Profile {
private int proifleno ;
private String firstname ;
private String lastname ;
.
.
.
int getProfileno ( ) { return this.profileno ; }
void setProfileno ( int profileno ) { this.profileno = profileno ; }
String getFirstname ( ) { return this.firstname ; }
void setFirstname( String firstname ) { this.firstname = firstname ;
}
void setLastname ( String lastname ) { return this.lastname ; }
String getLastname ( ) { this.lastname = lastname ; }
.
.
.
}
Then a fragment of my ProfileAction.java file:
.
.
.
ProfileForm profileForm = (ProfileForm) form ;
ProfileDBM dbm = new ProfileDBM() ;
dbm.setCon(con) ; // part of my DatabaseManager class
dbm.setTable(profileForm) ;
dbm.retrieve() ;
.
.
.
That populates the entire form so it can be displayed and manipulated by the
user. The other methods aid in creating, updating, and deleting.
Nothing really spectacular, I know. But I remember people talking about it,
and I just wanted to share what I've been doing. Again, we've had great
success in representing our existing database. And at this rate, we'll have
more than a Struts API for accessing our database. We'll also have
independent interfaces that could be used by any developer who wants the SQL
logic all worked out for them.

Yes, I think you've got it. Just to be clear, though, when you say we need to examine the sections in the header ..., the we here is Struts - you don't need to do anything in your application. Struts makes getParameter() et all work for multipart requests as well as regular requests. What you are seeing in the packages you've looked at is the parsing of a MIME part. The fields in a multipart/form-data request each conform to the specification for a MIME part, and they are separated by a boundary, which is a line containing a pattern defined in a header at the top of the request. Each MIME part consists of a sequence of MIME headers, followed by a blank line, followed by the data for that MIME part, known as the body. A MIME header takes the form header-name: value - for example, Content-type: text/plain. The body is just a bunch of data that conforms to the statements made about it in the headers. Every field in a multipart request is encoded this way. So where a regular query using GET might contain a query string like this: ...author=Martin... a multipart request would represent the same query parameter like this: -0123456789-- Content-disposition: form-data; name=author Martin -0123456789-- For a file upload, the difference is only that the Content-disposition header will include a file name, and the data can be binary if necessary. When a multipart handler processes a request, it is reading the data from an input stream provided by the container. Typically, for regular query parameters, it will store the value in a hash table. For file parameters, it will store the data in a file and retain information about that file. The Struts implementation uses the FormFile interface to provide access to that information.

normal and multipart
requests. Also, that class is definately going to change to
extend
javax.servlet.http.HttpServletRequestWrapper when
Struts adopts the Servlet 2.3 spec.
My purpose is
to temporarily storea binary and its file name in a bean until
the final form page
when the usersubmitsthe whole "kit and
kaboodle".
Instead of doing this,
you'd probably just want to stick to using an ActionForm bean that
has
aFormFile
property. TheFormFile interfaceshould suit your needs well,
as it has a getFileName()
method and methods to
retrieve the data written to a temporary file after
uploading:
public
classMultipageForm extends ActionForm
{
private FormFile
theFile;
public void setTheFile(FormFile file)
{
this.theFile
=file;
}
public FormFile getTheFile()
{
return theFile;
}
}
Part of the
problem is that I dont understand what is going on.It looks like the
request keeps the following:
"name" property
representing the form field name
"value"
property representing the Stringpath of the file you
uploaded
some binary
Stream data representing the file
Again, don't pay much
attention to the MultipartRequestWrapper class, concentrate on creating
an
ActionFormbean
that has aorg.apache.struts.upload.FormFile property representing your
file,and
normal String
properties representing your form data, just as you would normally create a
non
multipart
form.
I realy have no
idea, and I am looking around for answers but am coming up
empty.
Can someone sum
up what is happening here, what the request contains, what values the
request
works with, and
whatare the requirements.
Martin Cooper summed
this up nicely in anotherthread aboutuploading, but I'llgo
over it anyway:
1) Request comes in,
Struts goes to populate the form (BeanUtils.populate()) discovers
thatthe
content type of the request
is"multipart/form-data"
2) Struts goes to
populate the form, and creates a MultipartRequestHandler instance to
handle
the multipart request.
MultipartRequestHandler is an interface, the implementation can
change
at will and can be specified as an
init-param for ActionServlet, or as an ActionServlet
property
in
struts-config.xml
2a) In the
implementation that comes with Struts, the multipart form data is read as
follows:
Read the
data,
if it's a
string parameter, grab it's value and put it in a Hashtable for later
use
if it's a
file, read the file with a BufferedInputStream and store the data in a
temporary
file, then
wrap it in a FormFile implementation
(org.apache.struts.upload.DiskFile)
and hand
it back to BeanUtils (next step)
3)
BeanUtils.populate() uses the interface methods in MultipartRequestHandler to
grab the properties
that were retrieved from the
normal multipart request, the populates your ActionForm bean with
the
relevant
data.
4) The
Action is executed, and code in there manipulates the file according to
whatever you want to
do with it, for example, say we
wanted to take the previous form bean (above) and use it in the
action:
public class
UploadActionextends Action {
public ActionForward
perform(ActionMapping
mapping,ActionForm
form,
HttpServletRequest
request,
HttpServletResponse response) {
FormFile theFile = ((MultipageForm) form).getTheFile();
String filename = theFile.getFileName();
//and
so on...
}
Hope this helps, also consult that long thread
called
"uploading files requires immediate serialization?",
Martin Cooper does
a damn good job of answering questions about
this. Thanks again Martin...

Re: difficulty with logic:forward in template
The template is flushing the write buffer, and you can't redirect once the browser starts writing to the screen. Tom Miller wrote: I'm trying to use logic:forward in a .jsp file that is used in a template (via template:put). Apparently this is problematic, as I get the following exception when ForwardTag.doEndTag tries to execute pageContext.forward(path): java.lang.IllegalStateException: Cannot forward as OutputStream or Writer has already been obtained Yet the same logic:forward works perfectly when invoked in a plain .jsp rather than in a template. Can anyone suggest a workaround, or even better, something I don't know about that might solve this?
forward data
Hi,
i would like to know how to forward data

RE: Displaying data retrieved from a database
Jonathan A way of doing this is to use the java.util.ArrayList object. If you have a bean to represent a row of data eg TableRow CustID FirstName LastName RowBean Integer CustId; /* with get and set Methods */ String FirstName;/* with get and set Methods */ String LastName;/* with get and set Methods */ In your action perform, you can loop through your resultset, create a new RowBean for each Row and add it to the arraylist. You can then either assign the arraylist to the response object or the session object. In your JSP page, use the iterate tag to loop through your list. Theother option is to use the CacheResultSet from sun but I have not venture into that area. There are a number of discussions in this list about using the CacheResultSet.

My notion is that in your Actions perform() method you will make calls and get results. But where do you put the results? Do I save the data to a bean which I pass in the request to a waiting Tag class on the page I will forward to, and have that Tag class iterate through the beans data?This means I have to make Tag classes toread in passed beans. How are you all doing this in general. I am very interested. Jonathan
RE: Form with request scope
Hi Timothy Check your struts-config file to see if you have specified scope=request in your action definition for processN1.

Struts graph language?
I'd like to be able to diagram the work flow of my web application, which uses Struts. At the most naive level, I imagine it to be a graph of nodes (Actions, JSPs) and arcs (URIs and/or ActionMappings). Has anyone specified a graph language to include the following bits of information? * Actions * ActionForms * Request data (including attributes) At a glance, I'd like to be able to answer questions, such as the following? Q1. Where and how was a specific ActionForm instantiated and populated? Q2. What requests does a specific page (html or JSP) include? (Or put another way: where can I go from this page?). Q3. In presenting a given page, where did the data come from? (ActionForm? Bean? Was it on the session or the request? Under what name? etc) I've toyed with http://members.home.net/dlongmuir/struts.html, but found it limited to the data in the struts-config.xml. I'd like to include the JSPs as well as the data flow. Any ideas? -- Martin Zaidel, Senior Software Engineer Cortex eBusiness P/L, Melbourne www.cortexebusiness.com.au
Modifying Custom Tag HTML Libraries in Dreamweaver
From the archive I found that there is a Custom Tag Library Extension for Dreamweaver at http://www.shokker.com/ctlx/ctlx.zip. Can anyone share their experience of using it? satish

Is it possible to use the Struts framework without using any of the Custom Tag libraries? Thanks Satish
