Passing Object or object collection from action to jsp
HI,
When we want to pass an object or collection of objects to jsp we use value
object or collection of them.
For example imagine there is an action that wants to retrieve a list of
users from database and send it to jsp.
Here is the code of action:
UserListAction
{
execute()
{
//connect to database();
//execute the select statement();
//Get result set
Vector vecUsers = new Vector();
for size of result
{
User aUser = new User;
aUser.setName( rs.get(username));
aUser.setFamily( rs.get(family));
.
vecUser.add(aUser);
}
request.setPropertie(allUsers, vecUser)
}
}
Then in the jsp we use logic:iterate tag to navigate.
The only problem that we found is defining a value object named User, for
data transfer for each page. Is there any way that we can use the
dynamicForms or dynamic beans for passing data from action to jsp? Is it a
good solution any way?
Most of users use dynaForms are used for passing parameter from jsp to
actions. Is it correct? Is there other usages of dynaForms?
Thanks

There are a way to: When a click in a link in my jsp page, in address bar in my browser dont write the name of the action, and go direct to the jsp page (defined in action forward) ??? Thanks. Mauricio

Most of us go to great lengths to prevent users from accessing the JSPs directly, including putting them under WEB-INF or behind a security constraint. But if you have JSP's that don't need Action code in front of them, just put them somewhere accessible and use a plain old a href=filename.jspLink/a. If the link text/location needs to be dynamic, JSTL can be of help.

The easiest way is perhaps to simply add a redirect=true in your action mapping. However, be aware that this will kill your request attributes (since your request object is no longer forwarded..)

Re: Action to JSP - Works!!!
be aware that this is not a good thing to do in general ... as you'll never be able to make use of the request scope for variables which *will* bite you at some point down the road. If someone doesn't like the *.do at the end of the action name, then you really need to address a solution other than redirecting everything to JSPs. Just my $0.02. Mauricio T.

Re: Action to JSP
Quoting Geeta Ramani [EMAIL PROTECTED]: The easiest way is perhaps to simply add a redirect=true in your action mapping. However, be aware that this will kill your request attributes (since your request object is no longer forwarded..) Geeta's warning about one consequence is quite correct. So is the warning that you're going to make the performance of your application worse, because a redirect requires an extra round trip to the client (a forward is basically a glorified subroutine call that happens only on the server, which is why the browser doesn't change it's address -- it never knew what happened). personal-opinion In a web *applicaton* (as opposed to a web *site*), URLs should be thought of as an internal implementation detail, not a primary user-accessible feature. If you find your users getting distracted by the displayed URLs (or, worse, trying to bookmark them, which will never work unless your app takes pains to make it work), consider creating a frameset with a single frame in it (so the shown address never changes), or use JavaScript to create a new window that does not have a location bar. Other folks will disagree with me on this, of course, but in my general response is show me where the back button and bookmarks window are in a Swing app, and I'll make them available in my web app. :-) /personal-opinion Regards, Geeta Craig McClanahan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Action to JSP
Craig, I agree with everything you said, but would absolutely love a clarification from you on the following: Other folks will disagree with me on this, of course, but in my general response is show me where the back button and bookmarks window are in a Swing app, and I'll make them available in my web app. :-) I share your philosophy about how web^H^H^H applications should work, but there's a place where this philosophy abandons me. So I respond: If it's supposed to work like a swing app, then get rid of the bookmarks window and back button. Either that or make them unobtrusive. And now you know why I hate Web UI design. :-/ As such, this makes me an utter newb for the more esoteric front end issues involving a browser. So since my pre-struts experience put me mostly on the back end of web applications, what would you say are the best options for dealing with these things (struts or not) in a web application? I mean, I don't care if the back button still exists, but I don't want the user cursing my name every time he presses it without thinking about it. I personally _really_ hate it when this happens to me on my bank's site. TIA, Joe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How to pass information between action and jsp
Hi, I need to create input pages for crystal reports 9 reports. What I am planning to do is create Action, Form and JSP page for each input pages. From JSP the information will be passed to Form bean and Action will be called. Here what I will do is collect the parameters, generate the SQL. Now I need to forward it to a common JSP/Action page where I will collect the generated SQL and call crystal reports to generate the report. How can I pass the SQL info to the common JSP/Action page without using session? Here I assume if I use session then it could create issues if the user generates more than one report at a time. Of course, I can store the SQL for each report in different attribute and retrieve it. But user can not view the same report simultaneously with different parameters. Hope I explained things clearly.

Re: ActionErrors getting lost between action and JSP
When you call the saveErrors(...) method in the Action class' execute method, Struts will store the ActionErrors object under the default request attribute name org.apache.struts.action.ERROR. In the JSP, when you add the empty html:errors tag: html:errors/, Struts will look for this attribute in the request and display the errors. There is generally no need for you to save the errors under a different attribute name in the request in your Action class or specify a name attribute in the html:errors tag. You stated that you were saving the errors under the name errors in your Action class but your earlier code snippet shows that you were just calling saveErrors(...). Are you saving the errors yourself under a different attribute name? If so, are you doing this in addition to or in place of calling saveErrors()? It is not clear to me what your execute() method looks like. - Original Message - From: Parnell, Giles (AU - Sydney) [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] Sent: Thursday, January 16, 2003 5:03 PM Subject: RE: ActionErrors getting lost between action and JSP Hi there Giri I seem to have got this working... although not sure why it's doing what it is.

You need to save the ActionErrors object in the request in order to access
it from the JSP. The simplest way to do this is as follows:
In your Action class,
ActionErrors errors = new ActionErrors();
errors.add(some property name, new ActionError(some.key));
// The next step is important if you will use the default attribute
name
saveErrors(request, errors);
return mapping.findForward(failure);
In your JSP,

Hi there guys
Wonder if you can help. I am trying to get the struts actionErrors to
appear
on my error page.
I can get them working when I use the html:errors tag and specify the
exact
error I'm after, however I am now trying to output ALL the errors...
with
zero luck so far.
I have added two errors to the actionErrors object in my action like so:
if (true)
{
log.error(MAJOR DEBUGGING !!!);
actionErrors.add(careerPlan.help,
new ActionError
(errors.updatingError, fingers,
CareerPlan));
actionErrors.add(careerPlan.help,
new ActionError
(errors.XMLHydration ));
//request.setAttribute(errors, errors);
VOErrors errors = new VOErrors(actionErrors);
request.setAttribute(errors,errors);
log.debug(Wot is the size of the actionErrors:
+
actionErrors.size());
// XXX this always comes back as 2
// Try just place a string array on request
/*
String a = this is my first error;
String b = this is my second error;
String c = this is my third error;
errors.add(a);
errors.add(b);
errors.add(c);
request.setAttribute(errors, errors);
//XXX this didn't work either XXX
*/
return (mapping.findForward(failure));
}
The options i've tryed so far are:
a)creating actionErrors, adding it to the request, and then
forwarding
to
my error page
b)creating a VOErrors, adding the actionErrors to the VO and
forwarding
this VO to my error page
c)creating an arrayList of strings called errors, and forwarding to
my
error page
When tracing through my action, on leaving the action I can see that
there
are two errors

it from the JSP. The simplest way to do this is as follows:
In your Action class,
ActionErrors errors = new ActionErrors();
errors.add(some property name, new ActionError(some.key));
// The next step is important if you will use the default
attribute
name
saveErrors(request, errors);
return mapping.findForward(failure);
In your JSP,
html:errors/
This should output all the errors regardless of property name.

Subject: ActionErrors getting lost between action and JSP
Hi there guys
Wonder if you can help. I am trying to get the struts actionErrors
to
appear
on my error page.
I can get them working when I use the html:errors tag and specify
the
exact
error I'm after, however I am now trying to output ALL the errors...
with
zero luck so far.
I have added two errors to the actionErrors object in my action like
so:
if (true)
{
log.error(MAJOR DEBUGGING !!!);
actionErrors.add(careerPlan.help,
new ActionError
(errors.updatingError, fingers,
CareerPlan));
actionErrors.add(careerPlan.help,
new ActionError
(errors.XMLHydration ));
//request.setAttribute(errors, errors);
VOErrors errors = new
VOErrors(actionErrors);
request.setAttribute(errors,errors);
log.debug(Wot is the size of the
actionErrors:
+
actionErrors.size());
// XXX this always comes back as 2
// Try just place a string array on request
RE: ActionErrors getting lost between action and JSP
Hi there Giri I seem to have got this working... although not sure why it's doing what it is. I've included my jsp. I basically traced though the SaveErrors method and saw that it appears to be changing the name of the actionErrors object on the request. - In my action i save it with the name : errors. - In the SaveMethod it seems to replace errors with: 'org.apache.struts.action.ERROR' So now in my jsp, i just use that name in the name portion of the html tag, like so: html:errors name=org.apache.struts.action.ERROR/ Do you have any idea why this is happening ?

RE: ActionErrors getting lost between action and JSP
Hi there Giri
Thanks for your reply. The thing is... these are all the options I have
tried.
I've removed all the irrelevant code from my source for you to look at:
log.error(Add some errors to check this working !!!);
errors.add(test1, new ActionError(errors.moreThanOneEmployee));
errors.add(test2, new ActionError(errors.XMLHydration));
log.debug(Wot is the size of the actionErrors: + errors.size());
saveErrors(request, errors);
return (mapping.findForward(failure));
...
- As i said before... the logging statement shows two errors in the
actionErrors object.
- Tracing through the SaveErrors method the errors are still there...
- It's on leaving the action, and entering into the html:errors tag that it
appears empty.
- I don't need to use the property names, as I want ALL the errors to appear
on the page.
This is kinda driving me nuts - not sure where else I can trace ! Is there
anything I need in my struts.config?
Am i right is assuming that you DON'T need a form bean for the errors page.
ie - can i just put the errors on the request, and forward ?
Cheers
Giles
PS: ohhh... and both (errors.morethanoneEmployee and errrors.XMLHy...) are
defined in my app.resources

Hi everyone, Im new to structs so please be gentle. I have an action that forwards onto a jsp page with a form. When the form buttons are pressed a different action is called.

What's probably happening is an error is occuring that is being swallowed (at some point) and leaves you puzzled as to its origin. This has happened to me on occasion, and if a detailed search through my container's logs doesn't turn up anything, then its time to add more (strategically placed) debug statements to my code.

Not exactly sure, although I've gotten similar blank pages before. Double check that you have the input=somejsp.jsp in your action mapping in the struts-config.xml. Use a debugger or put a print on the top of the jsp page to see if you are even being returned to the correct page if validation produces errors.

RE: Call action from JSP
I don't use form because I don't need to submit any data. The action will
perform some logic against query string in request and data in session, and
forward wither to a success page or a failure page.
I could put this logic directly in JSP rather than in an action, but I
don't want so many Java code in JSP.

RE: Call action from JSP
You don't need to do it this way - you map the JSP to an Action class in
struts-config.xml and Struts will automatically send the data to the class
when the request URL changes.

RE: Call action from JSP
hmmm...why not check your condition and perform this logic in an action before you
even forward to the JSP in the first place?
b.t.w., you can always issue a response.sendRedirect( URL ) in the JSP scriplet, and
give it the URL-mapping for the action you wish to redirect to. I don't think that
doing this is a great idea, however. :)

RE: Call action from JSP
The JSP is an index.jsp and condition has to be check there.
If I use response.sendRedirect(URL) in the JSP scriplet, it seems that a
new request is created during redirect. Is there a simple way to keep the
previous request rather than create a new one?

I don't use form because I don't need to submit any data. The
action will
perform some logic against query string in request and data
in session, and
forward wither to a success page or a failure page.
I could put this logic directly in JSP rather than in an action, but I
don't want so many Java code in JSP.

Why would you want to call an Action class directly from a
JSP (outside a

RE: Call action from JSP
This was sorta mentioned before, but...why not have and index.do instead of
an index.jsp? Does index.jsp show something to the user or does it just
do some logic and then call the server?
If it does the latter, make it a .do

The JSP is an index.jsp and condition has to be check there.
If I use response.sendRedirect(URL) in the JSP scriplet, it seems that a
new request is created during redirect. Is there a simple way to keep the
previous request rather than create a new one?

hmmm...why not check your condition and perform this logic in an action
before you even forward to the JSP in the first place?
b.t.w., you can always issue a response.sendRedirect( URL ) in the JSP
scriplet, and give it the URL-mapping for the action you wish to redirect
to. I don't think that doing this is a great idea, however. :)

RE: Call action from JSP
I am new to struts and I don't know if this is of any use or if it is even
right, but when I wanted to call an Action when the user clicked a link I
used something like (no forms involved):
pBuild Database: a href=1-5-1_BuildDatabaseAction.doButton/a/p
and in my struts-config.xml had something like:
action
path=/1-5-1_BuildDatabaseAction
type=com.myapp.view.DBAdminClient
name=
input=/1-5_SAMainPage.jsp
forward name=db_create_successpath=/success.html/
forward name=db_create_failed path=/fail.html/
/action
I left name= because I wasn't doing anything with a form, just responding
to a user clicking on a link. I welcome comments letting me know if this is
the right way to be doing this or (rather more likely) that I am clueless
and that there is some other struts mechanism I should be using to handle
getting access to the action mappings when no forms are involved.
Thanks,

RE: Call action from JSP
I see nothing wrong with what you are doing. You don't even need the name
= in the xml. You might want to look at html:link in case you need to
do anything more with maintaining session, etc.

Not that I know of. You can put the request parameters you would like to pass on in
the query string of the URL you give to response.sendRedirect though.

This is fine. Just leave out both the name and input attributes, since
neither apply when there is not an ActionForm.

Re: Call action from JSP
Without Struts (sometimes even with it), I'd use either of the following
in a JSP:
jsp:forward page=urlSpec/
or
jsp:forward page=urlSpec
jsp:param name=name value=value/
...
/jsp:forward
For servlet code, I'd probably go with
RequestDispatcher.forward(ServletRequest request, ServletResponse
response), using ServletRequest.getRequestDispatcher(String path) to get
the dispatcher.

Hello everybody, In my web application I decided not to use frames and so I am using a table in a jsp file. my question is as follow: in the jsp file I want to know which action forwarded to this jsp file so that I will accordingly run the right code? Is der a way I could pass a Parameter from my Action class to the jsp file I am forwarding to ? Actually I want to include the corresponding jsp file into my main jsp file according to where the forward came from. Thanks for any Help Mohammed -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
