Re: Multipart forms
Thanks for your answer Niall. If I can't get the parameters in the reset()
method, then I don't know how to solve my problem. My ActionForm is on session
and it's a wizard-like one. The jsp has tabs to go to any page at any time.
What I do with non-multipart forms is something like this in the reset()
method:
String page = request.getParameter(page);
if (page != null page.equals(1)) {
String mycheckbox = request.getParameter(mycheckbox);
//if mycheckbox==null,the user hasn't checked it-set the property to N
mycheckbox == null ? setMycheckbox(N) : setMycheckbox(Y);
} else if (page != null page.equals(2)) {
...
}
This works fine (I'm actually using multibox fields). I'm not using server
validation in validate() method for several reasons, so I can't use it. Any
idea how can I do this with a multipart form?
Thanks again.
You can't get them in the reset() method. Parameters in multipart requests
are processed later and made available by wrapping the original request in
MultipartRequestWrapper and storing the normal request parameters in that
wrapper. Thats not done until the form is populated. The first chance you
get to do anything is in the form's validate method.

Hi! I have a problem when I want to get some parameters in the reset()

an ActionForm.
If the form is a normal form, then I simply call
request.getParameter(myparameter) and the parameter is retrieved with no
problem.
But if the form is of type multipart, then I always get null. The
parameter
table seems to be filled later, on the RequestProcessor. I need to get
parameters in the reset() method, specifically the page parameter, to

RE: [OT] RTF PDF export options
fop - http://xml.apache.org/fop/index.html
In my opinion better than iText - gives a bit more control. I had problems
with layout in iText - it adds funny paragraph spacing (especially with big
fonts). For fop - generate an XML file with data, write some XSL to
translate data into fop xml, and then process. Can create one xml file, one
xsl file, and translate it to what ever you want!
Says it doesnt support rtf yet... This is currently not integrated with FOP
but it will soon. Might be worth trying their mailing lists to see what's
happening with it.
With iText, you generate the whole thing programatically.
With iText or fop it's easy to do from an action:
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException {
ByteArrayOutputStream outPDF = null;
try {
//... generate data here
outPDF = ...
// set response headers
response.setHeader(Cache-Control, max-age=60);
response.setContentType(application/pdf);
StringBuffer cd = new StringBuffer();
cd.append(inline);
cd.append(; filename=);
cd.append(whatever);
cd.append(.pdf);
response.setHeader(Content-disposition, cd.toString());
response.setContentLength(outPDF.size());
// send pdf data
ServletOutputStream sos;
sos = response.getOutputStream();
outPDF.writeTo(sos);
sos.flush();
// return null so it just outputs data (no forward)
return null;
}
Hope that helps,
Daniel.

Re: Multipart forms
I can't think of anything you can do in Struts currently to get this to work
in the reset method - all the relevant code is in the
RequestUtils.populate() method and we would have to refactor the multipart
processing to resolve this (maybe you should open an enhacement request in
bugzilla for it).
Having said that, your code looks like it is doing whats needed to populate
your checkbox values - can't you just move this code into the Action's
execute method?

Multiple Resource Bundles
Hi, I try to use multiple resource bundles that get the strings from a database in an environment using JBoss, Struts and Velocity. I have defined two message-resources in struts-config.xml: message-resources factory=com.bk.web.struts.BKWebStringResourceFactory parameter=StringResources key=Strings/ message-resources factory=com.bk.web.struts.BKWebMessageResourceFactory parameter=ApplicationResources/ During startup of JBoss the createResource() method of both factories is called. But when I call a page on which the strings come from the StringResources bundle the getMessage() method of the ApplicationResources bundle is called. In the HTML code I've placed calls like this (: $msg.get(global.close, StringResources) msg is defined in toolbox.xml: tool keymsg/key classorg.apache.velocity.tools.struts.MessageTool/class /tool What's wrong with my call of $msg.get()? Did I miss anything? Best regards, Ralf. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Looking for Multiple file upload at once example
RE: Looking for Multiple file upload at once examplePaul,
I'm cc'ing the list so other can learn about this.
The problem is (unless it has been solved and I haven't heard about it) with
the commons file uploads cannot upload multiple files as the very same form
field name. Your velocity template shows the very same name,
uploadedFiles, used for each file. The last time it was discussed, I
believe the perp (er.. programmer. LOL) used one field and tried to upload
multiple file names in that one field (which is supposedly technically
allowed in file uploads, just not working in any struts-distributed commons
upload version). Your way of using one file name in different fields on the
page is essentially the same thing.
Have you thought of changing those fields to index arrays such as:
Attachment 1: input type=file name=uploadedFiles[0]/
Attachment 2: input type=file name=uploadedFiles[1]/
Attachment 3: input type=file name=uploadedFiles[2]/
Or you could name them randomly such as uploadFiles1, uploadFiles2,
uploadFilesA, uploadFiles27, etc. and use the
CommonsMultipartRequestHandler's getFileElements() method to iterate though
file uploads without worrying about their names. I suppose it all depends
on whether or not you need to I'd recommend using a form with that action,
then casting the form's getMultipartRequestHandler()
method a bit like so:
CommonsMultipartRequestHandler handler = (CommonsMultipartRequestHandler)
form.getMultipartRequestHandler();
HashTable files = handlers.getFileElements();
I haven't used it in a while so if I'm doing a typo on a method name, don't
kill the messenger. :)

David

Subject: RE: Looking for Multiple file upload at once example
Hi David.
I'm trying to use a form to upload several files, all at once.
I use Struts and Commons facilities (that is the FormFile interface).
Here's my action form:
public class AttachmentForm
extends ActionForm {
/* Files to upload */
private FormFile[] uploadedFiles;
public FormFile[] getUploadedFiles() {
return uploadedFiles;
}
public void setUploadedFiles(FormFile[] uploadedFiles) {
this.uploadedFiles = uploadedFiles;
}
}
And this is the html code I use to populate the action form (I'm using
Velocity, but I don't think this is really important):
html
body
...
form name=uploadForm method=post enctype=multipart/form-data
action=(...my action...)
...
Attachment 1: input type=file name=uploadedFiles/
Attachment 2: input type=file name=uploadedFiles/
Attachment 3: input type=file name=uploadedFiles/
...
/form
...
/body
/html

Depends on when you're doing the validtion.. using the javascript validation or server

html:form blah blah focus=${focusOn}
/html:form
and set the focusOn attribute in your action class.
javascript... you will have to write the javascript to do it...

Re: url rewriting
I think you can use url rewriting, and that won't put the jsessionid on it. It's sort of the other way around :-). The jsessionid parameter is the *result* of performing URL rewriting. If your browser client is using cookies, this will only show on the first request for a session - the container has to send the session id both ways (cookie and rewriting) the first time, because it doesn't know whether or not the client has cookies enabled. When the second request comes in with a cookie, the container notices and stops bothering to rewrite. Since the jsessionid is what is used for session tracking, you want to look at changing how session tracking is done. The Struts tags always do the URL rewriting calls for you, so that sessions just work. If you never want to see the rewritten URLs, most containers have a way to configure disabling this feature -- but, if you do, sessions will only work for clients that have cookies turned on.

Re: Multiple Values In Form Hidden Parameter
Hi Sahil,
You can do this sort of thing by using indexed properties:
html-el:hidden property=svalues[0] value=abc/
html-el:hidden property=svalues[1] value=def/
But in your bean you will need to add getters and setters that include
the index as a parameter:
private void setSvalues(int index, String val)
{
svalues[index] = val;
}
private String getSvalues(int index)
{
return svalues[index];
}

Hi Sahil,
You can do this sort of thing by using indexed properties:
html-el:hidden property=svalues[0] value=abc/
html-el:hidden property=svalues[1] value=def/
But in your bean you will need to add getters and setters that include
the index as a parameter:
private void setSvalues(int index, String val)
{
svalues[index] = val;
}
private String getSvalues(int index)
{
return svalues[index];
}

RE: Looking for Multiple file upload at once example
RE: Looking for Multiple file upload at once examplePaul,
I believe the problem lies with the Commons FileUpload package. Another way
to go over it is mentioned in this link:
http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED]
apache.orgby=subjectfrom=367131to=367131first=1count=2
Essentially, you can iterate over the parameters in the request (where
multiple fields with the same name would show up. do some sort of isFile()
method on that item, and then save it. You would just have to add enough
logic to handle uploaded files with the same form parameter name. The
Robert Priest example from the above link is a better explanation than my
writing it down.

David

Hi David,
I tried this solution just a few hours ago, before I received your answer!
It worked! The code I used is very similar to the snippet reported in your
mail.
I'd only like to know if the limitation you referred to regards the
BeanUtil package, the FileUpload package or Struts API...
Anyway, thank you very much, your help was VERY appreciated.
Thanks again :-)

Oggetto: RE: Looking for Multiple file upload at once example
Paul,
I'm cc'ing the list so other can learn about this.
The problem is (unless it has been solved and I haven't heard about it)
with the commons file uploads cannot upload multiple files as the very same
form field name. Your velocity template shows the very same name,
uploadedFiles, used for each file. The last time it was discussed, I
believe the perp (er.. programmer. LOL) used one field and tried to upload
multiple file names in that one field (which is supposedly technically
allowed in file uploads, just not working in any struts-distributed commons
upload version). Your way of using one file name in different fields on the
page is essentially the same thing.
Have you thought of changing those fields to index arrays such as:
Attachment 1: input type=file name=uploadedFiles[0]/
Attachment 2: input type=file name=uploadedFiles[1]/
Attachment 3: input type=file name=uploadedFiles[2]/
Or you could name them randomly such as uploadFiles1, uploadFiles2,
uploadFilesA, uploadFiles27, etc. and use the
CommonsMultipartRequestHandler's getFileElements() method to iterate though
file uploads without worrying about their names. I suppose it all depends
on whether or not you need to I'd recommend using a form with that action,
then casting the form's getMultipartRequestHandler()
method a bit like so:
CommonsMultipartRequestHandler handler =
(CommonsMultipartRequestHandler) form.getMultipartRequestHandler();
HashTable files = handlers.getFileElements();
I haven't used it in a while so if I'm doing a typo on a method name,
don't kill the messenger. :)

David

Hi David.
I'm trying to use a form to upload several files, all at once.
I use Struts and Commons facilities (that is the FormFile interface).
Here's my action form:
public class AttachmentForm
extends ActionForm {
/* Files to upload */
private FormFile[] uploadedFiles;
public FormFile[] getUploadedFiles() {
return uploadedFiles;
}
public void setUploadedFiles(FormFile[] uploadedFiles) {
this.uploadedFiles = uploadedFiles;
}
}
And this is the html code I use to populate the action form (I'm using
Velocity, but I don't think this is really important):
html
body
...
form name=uploadForm method=post enctype=multipart/form-data
action=(...my action...)
...
Attachment 1: input type=file name=uploadedFiles/
Attachment 2: input type=file name=uploadedFiles/
Attachment 3: input type=file name=uploadedFiles/
...
/form
...
/body
/html
Everytime I submit the form I obtain this exception:
javax.servlet.ServletException: BeanUtils.populate
org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254)
org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.j

Re: [OT] RTF PDF export options
From: Barnett, Brian W. [EMAIL PROTECTED] Forgive my naivety, Wendy, but what are the benefits of redirecting to a Servlet? My reasons, in no particular order... - I wanted a .pdf URL showing in the browser address line - the redirect lets me show a 'please wait' page - the sample code I started with was already a Servlet - it's not tied to Struts. It looks at something in the session, reads stuff from the database and spits out a PDF.

Re: Multipart forms
Thanks again Niall. I had already put the code in my Action, as you suggested.
I'm using a DispatchAction with a somewhat large number of methods on it and
now I need to call my new method in several of them, this is why I would have
preferred this code in the reset(), but this way works fine.
regards,
Diego
I can't think of anything you can do in Struts currently to get this to work
in the reset method - all the relevant code is in the
RequestUtils.populate() method and we would have to refactor the multipart
processing to resolve this (maybe you should open an enhacement request in
bugzilla for it).
Having said that, your code looks like it is doing whats needed to populate
your checkbox values - can't you just move this code into the Action's
execute method?

Subject: Re: Multipart forms
Thanks for your answer Niall. If I can't get the parameters in the reset()
method, then I don't know how to solve my problem. My ActionForm is on
session
and it's a wizard-like one. The jsp has tabs to go to any page at any
time.
What I do with non-multipart forms is something like this in the reset()
method:
String page = request.getParameter(page);
if (page != null page.equals(1)) {
String mycheckbox = request.getParameter(mycheckbox);
//if mycheckbox==null,the user hasn't checked it-set the property to
N
mycheckbox == null ? setMycheckbox(N) : setMycheckbox(Y);
} else if (page != null page.equals(2)) {
...
}
This works fine (I'm actually using multibox fields). I'm not using server
validation in validate() method for several reasons, so I can't use it.
Any
idea how can I do this with a multipart form?
Thanks again.
You can't get them in the reset() method. Parameters in multipart
requests
are processed later and made available by wrapping the original request
in
MultipartRequestWrapper and storing the normal request parameters in
that
wrapper. Thats not done until the form is populated. The first chance you
get to do anything is in the form's validate method.

Hi! I have a problem when I want to get some parameters in the reset()
method
of
an ActionForm.
If the form is a normal form, then I simply call
request.getParameter(myparameter) and the parameter is retrieved with
no
problem.
But if the form is of type multipart, then I always get null. The
parameter
table seems to be filled later, on the RequestProcessor. I need to get
parameters in the reset() method, specifically the page parameter, to
deal
with checkboxes in my wizard-style multipage form.
How can I do it in the simplest way possible?

RE: Tag question
Erik,
The getServletPath () returns the whole path to the servlet. As far as
I know, there's no method that returns exactly what you need ,so you'll
need to do the parsing (remove what is after the last /) by yourself.
Perhaps using scriptlet (nasty but will work).
c:set var=path
% ... the code .. %
/c:set
You could also have you action prepare this path variable and put it on
the request scope.

Re: [OT] RTF PDF export options

It's not free and in fact it's pretty expensive. We are leaning towards using this tool because of the ease of use they advertise. Supposedly you create a template in Word and you then can output to all types of different formats. I am curious to know if anyone has any experience with this tool before we shell out the two grand it costs. Thanks. Barnett, Brian W.

Validation headaches
Does anyone know if it is posible to use validatewhen in conjunction
with mask (or other validators)?
I cannot figure out how to make it work. Separately they work fine, but
when I try to use them together it never validates.
Here is the non-working config.
form name=dynaPhoneNumberForm
field property=phoneNumber depends=validwhen,mask
arg0 key=phoneNumber.displayname /
var
var-nametest/var-name
var-value(submit == 'delete') or (*this* !=
null)/var-value
/var
var
var-namemask/var-name
var-value^\d{4}-\d{4}$/var-value
/var
/field
/form
I'm using a LookupDispatchAction, and if I am calling delete, I do not
send the phoneNumber field. If I am not deleting, then I would like to
validate this against a regular expression.
(yes, the regex is working OK - they are not U.S. phone numbers.)

It won't give you just the servlet portion but it would look like it did if you

Re: Tag question
Heh, thanks Jim. Yeah, my memory is about like yours! But you are right,
I can work from that.
Cheers,
Erik

Thanks guys! Seems like there was a method I used to call in
my Servlets
that would only return the Servlet portion of the request URI . . . I
must have gone loco!
Were you thinking of request.getContextPath() ?
It won't give you just the servlet portion but it would look like it did if you
have a memory made out of stainless steel cheese like mine :)
On the other hand... that might make it easier to extract the servlet portion I
dunno...
I see that Struts puts a key to the servlet mapping /services/* in
some scope -- perhaps I can substring on that. I guess I'll have to
prepare this outside of the JSP as you suggest.
Thanks,
Erik

Hmm I must be doing something wrong. That's giving me the
same value as
Erez's example. Strange, I would have expected it to give me
/services. I wonder how I am causing it to give me
/usecase/page.jsp.

Hi Erik,
This one worked for me:
c:set var=v
%= request.getServletPath() %
/c:set
c:out value=${v}/

OT: Best practice for access to file from multiple web apps
We have PDF's that can be created by one webapp, but must also be served by other webapps. Obviously, fun is ensuing in trying to figure out the best to avoid hard coding paths, even in a configuration file. Dev, Test and Production are of course different enought that each environment requires a different configuraion file. We don't want to take the performance hit of storing the pdf as a blob. Can't build them on the fly for readonly (these are supposed to be immutable). can't do cool unix linking tricks ( not on unix, running on AS400s). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: OT: Best practice for access to file from multiple web apps
Jim, do you use ANT or Maven to build/deploy your projects? if so you can have them set up a config file for you based on the environment you're building to. andy On Tue, 20 Jul 2004 15:35:51 -0700, Jim Barrows [EMAIL PROTECTED] wrote: We have PDF's that can be created by one webapp, but must also be served by other webapps.

Re: OT: Best practice for access to file from multiple web apps
well, depending on your build process (and who is in control), setting up ANT really isn't all that difficult. and then you can have a config file for each platform you build to. i haven't had a chance (or taken the time) to play with Maven yet. it's built on top of ANT and apparently adds a lot of other cool features. you should check them out. sorry i don't have more specific help. :) On Tue, 20 Jul 2004 15:47:24 -0700, Jim Barrows [EMAIL PROTECTED] wrote: -Original Message- From: Andrew Close [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 20, 2004 3:44 PM To: Struts Users Mailing List Subject: Re: OT: Best practice for access to file from multiple web apps Jim, do you use ANT or Maven to build/deploy your projects? if so you can have them set up a config file for you based on the environment you're building to.

Forgive me for coming in late, but it's not obvious to me how big a problem the other webapps part of this really is. Lets use the term consumer webapp to be the webapp that wants to return the PDF in response to a request, while the producer webapp is the one that generates it on demand. (Note that, in a properly designed environment, no consumer should ever be able to tell whether the PDF was actually generated on the fly, read from a BLOB, or read from a file -- all the consumer knows is a URL, and it is up to the producer to decide what to do.) The first rule is that the consuming webapp has to know the name of the PDF that it wants. You could look this up in a database, if you wanted it to be dynamic -- but it will typically be a simple relative URL like bar.pdf, right? Next, lets assume the consuming and producing webapps are on the same server, but distinct from each other. If the producing webapp has a context path of /foo, then the relative URL for this pdf becomes /foo/bar.pdf instead of bar.pdf -- again, the host is implicit, so this URL should work in development, test, and production environments with no changes as long as producer and consumer are guaranteed to be on the same machine. The most general case is where producer and consumer webapps might be on different servers. An easy way to generalize this would be to configure the root part of the path (http://myhost/foo) in a context init parameter (or a JNDI environment variable), and make the consumer webapp glue that together with the relative path of the pdf in question on demand. Then, at most, you have to change one configuration setting as you migrate from development to test to production -- and, if you use a JNDI environment variable, the change is totally external to the WAR file that you're deploying, because you can configure it using the server's admin tool. Is it really any harder than this? If it is, I must be missing something. Craig - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Datasource problem again..
Great, that's always good to hear. Also consider providing your own context xml for each app with the war file, might save you some time in server restarts. Unless you changed server.xml through the administrative interface. On Wed, 21 Jul 2004 10:24:21 +0800, Koon Yue Lam [EMAIL PROTECTED] wrote: Tthanks for the help for all of u !

Re: Datasource problem again..
Good point.
I've done the same, ie setup a DefaultContext within the Host of
server.xml, and defined my data-source there.
I've still got a context.xml, but it's now down to just a couple of lines
ie to specify docBase, path and a logger.
It looks like this now:
?xml version='1.0' encoding='utf-8'?
Context docBase=/webapps/isurvey path=/isurvey reloadable=true
swallowOutput=true
Logger className=org.apache.catalina.logger.FileLogger
prefix=isurvey_log. suffix=.txt timestamp=true/
/Context
Just to make it clear what this is all about, you don't need to define a
Context in your server.xml.
In my case, my app is called 'isurvey', so I defined a file called
'isurvey.xml' containing the Context above.
I placed this file in {tomcat home}/conf/Catalina/localhost/ , and tomcat
was able to automatically detect the app.

John
