design question
I have 3 FormObjects. I have a newuser.jsp page containing the form userForm, in this form i put a javascript button with an onclick event, window.open with a popup (adresuser.jsp), with the form adresUserForm. Finally i have on the userForm another javascript button with a popup to specialinfo.jsp. This page contains the specialInfoForm. After closing these popups i want to have one action ( submitting the userForm ). How can i get the values from the 2 other formObjects ? Is there anybody that has a similar problem ... Thanks !
Re: design question
hi Drik once the user have filled up the other 2 forms in the pop window u can make object of those two forms into your final action and can get the values like Form1 form=new Form1(); Form2 form2=new Form2(); from1.getUserAddress(); from1.getCity(); Hope this works Regards Gurpreet Dhanoa - Original Message - From: dirk [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, December 24, 2003 2:54 PM Subject: design question I have 3 FormObjects.

RE: PDF file in browser
Hi,
Also do not forget to set the header so that the save as dialogue box is displayed in
IE...For that you have to set the content-disposition header ..
following is the code from our project..
Class FileOpenAction{
protected final void returnBinaryFile(
HttpServletResponse response,
String filename
String saveAsName)
throws FileNotFoundException, IOException {
response.setContentType(mimeType);
String fileExt =
WebUtil.getFileExtensionFromMIMEType(application/pdf);
setSaveAsHeader(response,saveAsName,fileExt);
File file = new File(filename);
response.setContentLength((int) file.length());
FileInputStream in = new FileInputStream(file);
OutputStream out = response.getOutputStream();
byte[] buf = new byte[4096];
int count = 0;
while ((count = in.read(buf)) = 0) {
out.write(buf, 0, count);
}
in.close();
out.close();
}
public static void setSaveAsHeader(HttpServletResponse response,String
saveAsFileName,String fileExt){
if(saveAsFileName == null){
return;
}
//to get over a problem in browsers due to which the file name must
have proper extension
if((fileExt != null)|| (fileExt.length() !=0)){
int index1 = saveAsFileName.indexOf(fileExt.toUpperCase());
int index2 = saveAsFileName.indexOf(fileExt.toLowerCase());
if((index1 == -1) (index2 == -1)){
saveAsFileName = saveAsFileName + . + fileExt;
}
}
response.addHeader(Content-Disposition, attachment; filename= +
saveAsFileName );
}
}
Also another thought..Why use another servlet..Just use another action like we
do..This way you can use all the existing framwroek..Like authorisation etc

if you can reveal the location of the PDFs on your web server.
Simply put your pdfs under a www/app.com/pdfs/*.pdf and give them links as
you want.
if you wish to maintain some security.
1. send a request to a servlet wit some pdf code or file name
2. open the given file from the file system whereever it is.
3. convert it into stream.
4. push the stream back to browser.
note - must set the appropraite mime/type before you push the stream back.

Re: design question
If the forms are in different windows then instantiating new forms I dont think will work. If you want a non javascript way of doing things then you'll want to scope the master form to the session, and then keep populating to from your subforms . However you do this I imagine that scoping the master form to session is the way forward and retrieving and populating it in the actions processing your secondary forms. action path=/master name=masterForm scope=session... action path=/gimp/submit name=gimpForm scope=request type=com.sparrow.struts.GimpAction.. You could make one form property of the master form of type gimpform or store this as a map. html:form action=/gimp/submit.do public GimpAction ... GimpForm gimpForm = (GimpForm) form; MasterForm masterForm = (MasterForm) session.getAttribute(masterForm); masterForm.setGimp(gimpForm); or if you're using a map to store the properties of gimp in your masterForm Map gimpMap = BeanUtils.describe(gimpForm); masterForm.setGimp(gimpMap); Hope this helps Mark On 24 Dec 2003, at 09:50, Gurpreet Dhanoa wrote: hi Drik once the user have filled up the other 2 forms in the pop window u can make object of those two forms into your final action and can get the values like Form1 form=new Form1(); Form2 form2=new Form2(); from1.getUserAddress(); from1.getCity(); Hope this works Regards Gurpreet Dhanoa - Original Message - From: dirk [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Wednesday, December 24, 2003 2:54 PM Subject: design question I have 3 FormObjects.

Navigation Stack
Hi:
I'm working with a Struts 1.0 application. I extended Action to create a
base action that handles backwards navigation in a stack fashion.
Each method calls a saveStep method to the stack. This step has form,
mapping and dispatch name. Base action has a method called stepBack
that can be called from the browser by clicking the back button (not
browser back button, but a submit button). This stepBack method executes
the last step in the stack and goes backwards. Another features exists
like checkPoint step, and an undoStep to return from a validation in
Validator Form.
public ActionForward stepBack(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
NavigationStack ns =
this.retrieveNavigationStack(request);
synchronized(ns) {
//if not reloading
StackStep ss = null;
if(this.isTokenValid(request)) {
try {
ns.pop(); //last step, ignore it.
ss = ns.pop();
} catch (Exception e){
return this.handleEmptyStack(mapping, form, request,
response);
}
} else {
ss = ns.getLastPopped();
}
return ss.process(request, response);
}
}
public void saveStep(ActionMapping mapping, ActionForm form,
HttpServletRequest req, String dispatchName, boolean isCheckPoint) {
//si no se indicó invalidar el grabado...
if(this.isStepValid(req)) {
NavigationStack ns =
this.retrieveNavigationStack(req);
synchronized(ns) {
StackStep newStep = new
StackStep(dispatchName, mapping, form, isCheckPoint);
newStep.setServlet(this.getServlet());
//lo apila siempre y cuando sean
distintos (el último y el nuevo)
if(!newStep.equals(ns.getLast())) {
ns.push(newStep);
}
this.saveNavigationStack(req, ns);
}
}
}
I would like to know what you thing about this kind of navigation
management and know how are you dealing with this problem. With this
solution I can link 2 use case action (I designed one action for each
use case) and click back button to return wherever i was called.

Problem with multibox check state
Hi,
I have a jsp input form with dynamically generated multibox, I need to fill these
boxes with checked and unchecked state once the user selects a previously saved
record. I need to know how to resolve this problem.
I have done the same with a single multibox, using the set('property name', value) in
the action component. But for dynamically generated multibox what need to be done.
I have set the component name in the 'form bean' tag as 'java.lang.string'.
This is a very urgent requirement and might be a simple problem for you gurus.
Thanks for any help on this issue.

RE: Navigation Stack
Hi,
I found the idea interesting..
But I have a couple of questions...
the assumption you are making here is entire request parameters are captured in the
form...How else can you call some action if it does not have access to all the request
parameters..
Also it means that the action have very clean code and no forwarding of Objects as
request attributes etc...
But if these rules are followed,what you have done will definately work.
regards,
Shirish.

RE: Navigation Stack
Im working with struts1.1 myself.
Our application has quite a few screens that correspond to records in the
application, and these records are often related to other records in the
application - ie you might need to pick one from a drop down or such like.
We were able to give the user the ability to create (or edit) a record
related to the current screens record, and when finished come back to the
current screen (to select the newly created record) and keep working with
all fields entered so far preserved but without the record yet being saved.
This is allowed to any depth. (Our app can be quite complex to configure so
this also helps guide the user through all the records that need to be
configured for something (can be quite a few for something like configuring
the app to use a certain RosettaNet PIP with a certain partner or such like
stuff) - thus making it a sort of navigation stack ).
It works by using a stack of what I term Operation Context objects - in
that each element in the stack contains info related to the context of a
particular operation (ie : edit a type X record, etc...). The Operation
Contexts may be stacked, so if during editing a type X record the user
realises they need to create a type Y record for X to refer to they can go
off and do it, and when that operation is complete they will be brought back
to the screen for the X record...
Ive modified RequestProcessor so it will look for session scoped actionforms
in the operation context rather than the session if there is an operation
context associated with this request (managed by url rewriting to keep track
of the OpCons unique id). This has the added advantage of allowing me to
have several windows all working with the same record type (ie: same action
and type of action form) where the form is session scoped, without them
interfering with each other as would be the normal case with session scoped
action forms.

I want to use an update user details page in my application which uses a form to display the current user details and updates any changes. Im having problems displaying the information of the user bean in the value property. What I want is html:text property=name value=current users name / Ive tried the following which is giving me errors: html:text property=name value=bean:write name=currentUser property=name / / Anybody know how to do this? Thanks
Re: html:text value=? problem
html:text property=name value=%= user.getName() % /
or
html-el:text property=name value=${user.name} /
You can also populate in the refering action (assuming you've one), i
think this is better and keeps your form cleaner and thus perhaps more
reusable.
theForm.setName(Brian);
or dynaactionform
theForm.set(name,Brian);
html:text property=name /
will render to
input type=text name=name value=Brian

security of html pages max file size property
Hi all,
I have two questions:
1) I have a problem with the help menu of my application wich contains html
pages.
I would not like to access those pages without being log on, so I access
them via a secure Action that just do a forward to the good page:
action path=/help/helpAction
type=com.bnpparibas.primeweb.web.help.HelpAction
name=helpForm scope=request validate=false
forward name=menu path=/help/help.jsp/
forward name=banner path=/help/help_banner.jsp/
forward name=mainFrame path=/help/help_mainFrame.jsp/
forward name=home path=/help/help_home.htm/
forward name=index path=/help/help_index.jsp/
forward name=options path=/help/help_options.htm/
forward name=report path=/help/help_report.htm/
/action
But I still can access the pages without being log on, just by writing the
url in the browser.
I have so done a filter to disable the user to access this page, but I
would like to avoid this solution, I would prefier use Actions only. do you
have any idea.
2) File Upload: whe the clien exceed the max upload file size, I would like
to display a message via the message framework, which looks like this:
maxLengthExceeded= Maximum file size exceeded ({0})
where {0} is the max size setting in struts-config.xml. But I did not find where I can
take programaticly this information

Re: PDF file in browser
You 're forgetting two things...
1- He wants to show a pdf file in a new browser
to do that, you must set the apropiate target into de A tag...
a href=xxx.pdf target=_blankxxx/a
target=_blank will open the link in a new window.
2- This, will only work if the users uses Internet Explorer...cause it's an
activeX container, unless the
user changed it, by default pdf files and other documents, will be opened
inside explorer...but other
browsers such as netscape, mozilla and opera, are not activeX container, so,
pdf files will prompt the user
to download them, or open directly.

Subject: security of html pages max file size property
Hi all,
I have two questions:
1) I have a problem with the help menu of my application wich contains html
pages.
I would not like to access those pages without being log on, so I access
them via a secure Action that just do a forward to the good page:
action path=/help/helpAction
type=com.bnpparibas.primeweb.web.help.HelpAction
name=helpForm scope=request validate=false
forward name=menu path=/help/help.jsp/
forward name=banner path=/help/help_banner.jsp/
forward name=mainFrame path=/help/help_mainFrame.jsp/
forward name=home path=/help/help_home.htm/
forward name=index path=/help/help_index.jsp/
forward name=options path=/help/help_options.htm/
forward name=report path=/help/help_report.htm/
/action
But I still can access the pages without being log on, just by writing the
url in the browser.
I have so done a filter to disable the user to access this page, but I
would like to avoid this solution, I would prefier use Actions only. do you
have any idea.
2) File Upload: whe the clien exceed the max upload file size, I would like
to display a message via the message framework, which looks like this:
maxLengthExceeded= Maximum file size exceeded ({0})
where {0} is the max size setting in struts-config.xml. But I did not find
where I can take programaticly this information
Thanks for your help.
So this is Christmas
And what have you done
Another year over
And a new one just begun

RE: retrieving values from application.properties file
This might be the wrapper you are looking for

return MessageResources.getMessageResources(ApplicationResources);
}
//getMessageResources().getMessage( key );
The API has lot of other methods.

You 're forgetting two things...
1- He wants to show a pdf file in a new browser
to do that, you must set the apropiate target into de A tag...
a href=xxx.pdf target=_blankxxx/a
target=_blank will open the link in a new window.
2- This, will only work if the users uses Internet Explorer...cause it's
an
activeX container, unless the
user changed it, by default pdf files and other documents, will be opened
inside explorer...but other
browsers such as netscape, mozilla and opera, are not activeX container,
so,
pdf files will prompt the user
to download them, or open directly.

Hi,
Also do not forget to set the header so that the save as dialogue box is
displayed in IE...For that you have to set the content-disposition header
.
following is the code from our project..
Class FileOpenAction{
protected final void returnBinaryFile(
HttpServletResponse response,
String filename
String saveAsName)
throws FileNotFoundException, IOException {
response.setContentType(mimeType);
String fileExt = WebUtil.getFileExtensionFromMIMEType(application/pdf);
setSaveAsHeader(response,saveAsName,fileExt);
File file = new File(filename);
response.setContentLength((int) file.length());
FileInputStream in = new FileInputStream(file);
OutputStream out = response.getOutputStream();
byte[] buf = new byte[4096];
int count = 0;
while ((count = in.read(buf)) = 0) {
out.write(buf, 0, count);
}
in.close();
out.close();
}
public static void setSaveAsHeader(HttpServletResponse response,String
saveAsFileName,String fileExt){
if(saveAsFileName == null){
return;
}
//to get over a problem in browsers due to which the file name must have
proper extension
if((fileExt != null)|| (fileExt.length() !=0)){
int index1 = saveAsFileName.indexOf(fileExt.toUpperCase());
int index2 = saveAsFileName.indexOf(fileExt.toLowerCase());
if((index1 == -1) (index2 == -1)){
saveAsFileName = saveAsFileName + . + fileExt;
}
}
response.addHeader(Content-Disposition, attachment; filename= +
saveAsFileName );
}
}
Also another thought..Why use another servlet..Just use another action
like
we do..This way you can use all the existing framwroek..Like authorisation
etc

if you wish to maintain some security.
1. send a request to a servlet wit some pdf code or file name
2. open the given file from the file system whereever it is.

[OT] Synchronized access to application-scoped object
Holiday Greetings to All! Quick design question - Is it possible to synchronize an application-scoped object between two servlets within the same web application? I have a servlet that I have written that maintains a List object that is stored in application scope. This servlet basically creates a new List, then replaces the existing one (uses the same name for the object). My second servlet (Struts) simply accesses this List in a read-only fashion - no updates. I can write a basic spin-lock type of mechanism to ensure that my Actions do not try to access this List while my first servlet is replacing the object, but I'm wondering if there is an easier approach, possibly using a synchronized block using the application object Comments?

logic:iterate problem (not loading complete jsp)
Hi all-
I have a problem which i'm sure someone else must have gone thru. I have a
collection of Value Objects that hve properties like firstName, lastName
etc. I wrote a getter in the form bean that returns this collection of
value objects
[code]
// This is my IncompleteFolderAction.java
.
while(rs.next())
{
application = new ApplicationVO();
application.setFirstName(rs.getString(FIRST_NAME));
application.setLastName(rs.getString(LAST_NAME));
...
}
// This is my IncompleteFolderForm.java (form bean)
...
public Collection getApplications()
{
return applications;
}
...
[/code]
the following is the code i wrote on the jsp to access this collection and
iterate thru the value objects
logic:iterate id=appList name=incompleteFolderForm
property=applications
tr
tdbean:write name=appList property=firstName//td
tdbean:write name=appList property=lastName//td
..
/tr
/logic:iterate
and my struts-config.xml contains an action name=incompleteFolderForm
that maps to the form-bean IncompleteFolderForm
My problem is i dont see anythign on the jsp once it returns ..it's all
blank .. but the getter methods are being accessed coz i printed a string
from the getApplications() and it did print. when i tried to view the
source of the jsp .. it shows only half (or less, i dont know) of the
source code ..it's as if the page stopped loading .. i've been working on
it since like 2 days now.. and it'd be really great if anyone could help me
or point me to some place where i can get some info
I'm using Apache Tomcat 5.0 with Struts 1.1 ...
Thankx a lot :)

RE: Re[2]: Select without selected value
-Original Message- I use select with multiple=false and I don't set the parameter's value. As result I get: form name=faqForm method=post action=/dp/showFaq.do select name=id onchange=submit() option value=1Test1/option option value=2Test2/option /select /form So none of options has selected attribute, but first option is selected on the page.

Re: Select without selected value
an option will only be selected by default if the form property has been set to a value or there is a match in an available scope (like a parameter with the same name as the form property). Otherwise it will just do its thing. I'd use a simple action without a formbean for something like a navigation menu form action=c:url value=/process.do / method=POST select name=id ... String id = request.getParameter(id).toString(); get the values out of the parameter map as you would with a plain old servlet. but nothing wrong with using an action form, especially for consistency.

Easy question: iterate

RE: Easy question: iterate
I think life would be easier if you store your Category_VO objects in a
java.util.Collection, then use JSTL forEach tag. Something like this:
%
Collection v = new Vector();
v.add( new Category_VO(cat 1) ); //Assuming your constructor takes a
String which is the shortTitle
v.add( new Category_VO(cat 2) );
v.add( new Category_VO(cat 3) );
v.add( new Category_VO(cat 4) );
request.putAttribute(categories,v);
%
c:forEach items=${categories} var=cat
c:out write=${cat.shortTitle}/

RE: Select without selected value
Or you can override the form value like this html:select ... value=x If the value you set doesn't exist then nothing will be selected. Which means the first item will be selected, because something always is (if we are talking about a dropdown and not a multiselect).

Re: [OT] Synchronized access to application-scoped object
Quoting Jerry Jalenak [EMAIL PROTECTED]: Holiday Greetings to All! Quick design question - Is it possible to synchronize an application-scoped object between two servlets within the same web application? I have a servlet that I have written that maintains a List object that is stored in application scope. This servlet basically creates a new List, then replaces the existing one (uses the same name for the object). My second servlet (Struts) simply accesses this List in a read-only fashion - no updates. I can write a basic spin-lock type of mechanism to ensure that my Actions do not try to access this List while my first servlet is replacing the object, but I'm wondering if there is an easier approach, possibly using a synchronized block using the application object Comments? Synchronizing on the List instance won't help much, because of the way you're replacing the old one with a new one -- but it's probably unnecessary as well, since the servlet reading the old List and the servlet creating the new List are never manipulating the same object instance. If the servlet doing the modifying was doing it in place on the existing List instance, then synchronizing on that instance would indeed be appropriate. TIA!

Re: Easy question: iterate
Looks like you should copy what your view needs from your model rather
than shoe-horning in your data objects into your jsps.
Have a simple bean called Category in this example with a title
property.
Category_VO[] pcatResults = dao.selectTopLevel();
ArrayList categoryList = new ArrayList();
while(pcatResults.next()) {
Category category = new Category();
String title = pcatResults.getShortTitle();
category.setTitle(title);
categoryList.add(category);
}
request.setAttribute(categories, categoryList.toArray());
Any good?
Wont need the useBean stuff, i just didn't know what you were trying.

hi the thing is: i have a bean called Setor, and this bean has an attribute called quadras, which is a collection. ok, i can retrieve the ben using hibernate, store it in a session (now talking about struts) and go to my jsp page. there, i have this piece of code: tr tdbean:write name=setores property=nome //tdbrbr tdbean:write name=setores property=comentario //tdbr /tr logic:iterate id=quad name=setores property=quadras tr tdbean:write name=quad property=nome //td tdbean:write name=quad property=comentario //td /tr /logic:iterate Of course, the session was set this way: (setores, setoresObj). so, with the bean tag, i grab the setores bean, and print its non-collection attributes. then, i have to iterate over quadras. is it the correct way? i've read hibernate's docs and noticed i can't get this collection values if the many-to-one association is a lazy one. how to get and iterate over this collection, then? thanks for the attention Otávio Augusto On Wed, 24 Dec 2003 13:24:04 -0700 David Erickson [EMAIL PROTECTED] wrote: What kind of problem are you referring to with lazy instantiation?

One last question - during the time period where the getServletContext().setAttribute() is executing in Servlet_1, is there any concern about collision with an access from Servlet_2 (Struts)? I guess I'm unsure whether the setAttribute() method is synchronized or not (the javadoc doesn't say.) You can assume that your app doesn't have to worry about calling getServletContext().getAttribute() from one thread, and getServletContext().setAttribute() from another thread at the same time -- the container guarantees that the internal data structure it is using (in the case of Tomcat, it's a HashMap that *is* synchronized appropriately) is thread safe. The only objects that the application has to worry about w.r.t. thread safety are its own. Thanks!

Quick design question - Is it possible to synchronize an application-scoped object between two servlets within the same web application? I have a servlet that I have written that maintains a List object that is stored in application scope. This servlet basically creates a new List, then replaces the existing one (uses the same name for the object). My second servlet (Struts) simply accesses this List in a read-only fashion - no updates. I can write a basic spin-lock type of mechanism to ensure that my Actions do not try to access this List while my first servlet is replacing the object, but I'm wondering if there is an easier approach, possibly using a synchronized block using the application object Comments? Synchronizing on the List instance won't help much, because of the way you're replacing the old one with a new one -- but it's probably unnecessary as well, since the servlet reading the old List and the servlet creating the new List are never manipulating the same object instance. If the servlet doing the modifying was doing it in place on the existing List instance, then synchronizing on that instance would indeed be appropriate. TIA!

Nighty Builds of Struts-Faces Integration Library
Nightly binary builds of the Struts-Faces Integration Library, updated to work with the new beta release of JavaServer Faces, are now available: http://cvs.apache.org/builds/jakarta-struts/nightly/struts-faces/ As always, the source code for this library is in the contrib/struts-faces directory of the nightly Struts source distro: http://cvs.apache.org/builds/jakarta-struts/nightly/src/ This code is *not* ready for prime time yet, but the test application at least works. Tops on my list is ensuring that it works with Tiles as well ... most likely by having two different request processor subclasses and making you configure the one you need based on whether Tiles is in use or not. Not quite as transparent as the old release, but it should be able to work.

How Do I Handle Two Action Forms
I am stuck and need your knowledge and experience. When the button is my JSP is clicked, there are two action forms involved, threadForm and postForm. The threadForm is populated by hidden fields and text fields that are passed from the JSP. All the properties of the threadForm are to be inserted into a table in the database by the threadInsert() method and this method returns a primitive int threadID. The properties in the postForm are also populated by hidden fields and text fields that are passed from the same JSP, except that the postForm has one additional properties - threadID, which is obtained from the insertion of the threadForm into the database. Thereafter, all the properties of the postForm are to be inserted into another table in the database by the postInsert() method. How do I handle this situation? Please help. __ Do you Yahoo!?
