Subject: Changing Request Parameters


I am forwarding from one Action to Another. I need to tweak the request
parameters. Is there a way to do this?

I tried to set the reqest value by calling the FormBean and set it from the
action. But, it doesn't carry over to the next Action. I can't find a way to
change the request parameters. Please help.

I saw some discussion on the archive. But, is pretty aimless and not very
clear.

I am running Servlet 2.2 so don't tell me about getParameterMap().

RE: Struts vs Template Engine or Both

[Phase Communcations]

If find it interesting that the argument of placing scriptlets into a jsp
page is reason enough not to use them. Has anyone heard of custom tags. If
you want to avoid placing scriptlets in your page then develop a tag that
handles the data. I have been developing in jsp for a year and a half and
have NEVER put a scriptlet in a page. I have found struts/jsp to be a great
platform for separating view and control. The other thing is let's not get
religious about MVC. There may, rarely (if ever), be an instance where
someone needs to grab some data form a view (hisss). But I have seen SQL
tags and other such tag-libs that might do someone some good who is working
on a project and wants to get a portion of it done and working. Then we can
go back and put things the way they should be (MVC). I have worked in
production enivronments where you need to get it done yesterday and you have
to write sloppy code to get it done. That's life. It's nice to have options.
I see that JSP provides that. Struts allows for the flexibility. This is a
good thing.

I am not getting in to a holy war over struts/jsp versus struts/velocity. I
am just saying. Stop with the scriptlet argument its not that major of a
point and your designers don't have to see a stitch of it and they shouldn't
have to use it if you understand what you are developing with and how best
to use it.

Thanks for allowing the soundoff,

Dave,
a Struts user posted the following message yesterday. I think
it pretty nicely summarizes what makes Velocity templates attractive
to some developers.

We are working on integrating Velocity tightly with Struts. A prototype
with several simple application examples is available here:

http://husted.com/struts/resources/velstruts.zip

This contains a *.war file. Put the *.war into the webapps directory of
a Tomcat installation and restart. Then point your browser at
http://server:port/velstruts/ to see and try the examples. We are
currently in the process of redesigning the API and putting together
documentation. I hope for a first release version in the comming weeks.
I will announce major changes on this list.

Regarding your questions:

- As you can see in the examples, JSPs and Velocity templates can be
used in the same application. No restrictions.

- Regarding the learning curve of Velocity. The language is
really simple. Less than 10 directives. Velocity templates don't
allow Java scriptlet. If you have been relying on that feature
a lot, existing applications might need some redesign to be able
to use Velocity. Velocity really enforces a clear separation between
view and control.

- Regarding performance: Many users have reported that they
obtain about the same performance with JSP and Velocity (it really
depends on the types of templates). So, performance it not an
argument for or against one of the two technologies. We plan to do
some more performance tests with a first release version.

Struts-config initialization

[Phase Communcations]

When the struts-config file is initialized, does it place the ActionMappings
into a bean or are the ActionMappings checked against the struts-config file
each time a */do/* url is accessed? My reason for asking is that I plan to
create a config file that will define the content available to a page based
on it's Action Mapping. I plan to write an extendable generic ActionClass
that can read the config file and determine what data it needs to provide to
the page based on the Action Mapping. The page tags will then determine the
placement of the data on the page. I am just wondering if I should place all
of the mappings into an app bean to be accessed by the GenericAction or
leave them in the config file and parse the config for mappings. The answer
seems to be the bean. But, I would like to do it in the same manner that
Struts does.

It sounds fine to me.

The important thing is to follow the layers pattern

[ view ] | [ controller ] | [ model ]

The view can talk to the controller, and the controller can talk to the
model, but when you le the view and model talk, it starts to spin out of
control.

I like to call a business method and get back a collection of beans, so
that the Action does not even have to bother with that.But since the
contoller and the model are on adjacent layers, the Action could also
walk through a result set, if that works for you. The only thing is to
get the connection back into the pool as soon as possible.

For transfering data between beans, the BeanUtils can also be helpful.

RE: SQL in Logic Bean or Action class

[Phase Communcations]

A quick hypothetical scenario:

I have an action class that needs to pass a list of addresses to the view
for display.
I have a logic bean that contains a sql call to a database and retrieves
address info.
The resulset returns the following fields in each record: NAME, ADDRESS,
CITY, STATE, ZIP
I have a "databean" that has the following methods: setName(), setAddress(),
setCity(), setState(), setZip()
An ArrayList(Collection) is created.
For each record in the resultset the fields are used to populate the
databean (ie NAME -> setName()) by calling it's property setting methods.
Each bean populated is added to the ArrayList.
Upon the end of the resultset the ArrayList is passed into a scope (request
for example) by the Action class and named "addresslist".
The list of addresses then become available to the view for iteration and
display.

Where am I crossing boundaries in this scenario?

You are on the right track.  Keep the sql with the model.  The only thing is
don't let your collection of "databeans" make it to the jsp.  That would
then tie your presentation to the model.  Very bad.  There should be another
set of beans that represents more of what the view is like.  Often times in
the view beans all the data types will be string to make the validation a

Capturing a /do url with querystring intact

Is it possible to capture a do/ style url with the QueryString intact.
Basically what I need to accomplish is to capture the full url so that when
the client enters an admin area it bookmarks where they were so that they
can return back to where they were before entering the admin area. It is a
content management app and it is possible that they will be managing content
that shows up under a url that has querystring data.

Multipart Iterator Error

[Phase Communcations]

I have a view that contains a form (Form-A) that is a multipart/form-data
that is submitted to an action (Action-A). Form-A is empty when the "cancel"
button is pressed. The "cancel" button returns the user to a previous form.
This is accomplished within Action-A. Action-A looks to see if the "cancel"
button is pressed and when the "cancel" button is pressed it forwards to the
previous by forwarding to Action-B. Action-B should then populate it's
corresponding form (Form-B) and display it's view. But I get the following
error instead. Any answers?

Multipart Iterator Error

[Phase Communcations]

I have a view that contains a form (Form-A) that is a multipart/form-data
that is submitted to an action (Action-A). Form-A is empty when the "cancel"
button is pressed. The "cancel" button returns the user to a previous form.
This is accomplished within Action-A. Action-A looks to see if the "cancel"
button is pressed and when the "cancel" button is pressed it forwards to the
previous by forwarding to Action-B. Action-B should then populate it's
corresponding form (Form-B) and display it's view. But I get the following
error instead. Any answers?

Action Forwarding with /do style url

[Phase Communcations]

I think this is a simple question. I have been developing an app using the
/do command line structure url. I have a form that is submitted to an
action. The action at the start checks to see if the "return" button is
pressed. If the "return" button is pressed the action class should forward
to another action that will initialize and populate a form in another view
and display that view. Something seems to be going wrong with my mappings or
it may be that it is not possible to forward to another action from within
an action class.

For example:

   -- return statement within an Action class called by a form submittal
   return mapping.findForward("return");

whereas the "return" forward is mapped to - "/admin/content/edit" within the
struts-config.xml.

Is this possible to do or can I only forward to a view from within an
action?

If this is not possible how can I forward back to an action that needs to be
initialized to populate a form after a submission check determines that a
forward is needed?

Thanks,
Brandon Goodin

RE: Where should I store image files?

[Phase Communcations]

I would suggest a directory. Databases can handle the binary info. But, it
is not good for performance. Both will work but I would place a file
path/url in the database to reference the images and store them in a
directory.

Hi Folks

I have a jsp/servlet web app and am not sure where I should keep the
image files.  The image files are constantly getting added to, ie people
can upload new images and they should be stored somewhere, either in a
database or in a directory somewhere.  I am not sure which is the best
way to go.  Can someone please tell me where they think I should store
the images.

Cheers

Tony

Has anyone succefully swapped out the "?" and the "&" in a querystring with
another symbol , such as "/". A problem with various search engine spiders
(not all, but, several) is that they will not move past a ?. It would be
advantagous to allow for the use of a more compatible querystring (a way
around) especially when we  are talking about shopping carts and sites with
dynamic content that is accessed through links and not forms. I have seen
this done with other sites using php :( and it is very effective on the
search engines. I am endeavoring myself to figure a way around the "?" and
"&", using Struts (of course). Yet, if someone has attempted this succefully
I sure would appreciate some wisdom or code (code would be better, I think).
Otherwise, I will embark on my crusade alone.

I think from another post, the problem lies in that the request is being
redirected rather than forwarded. Upon the redirect, the webserver chokes on
it. Perhaps the answer is to use the subclass of ActionForward that sets
forwarding to true by default.

Haven't had the time to check this. However, I get the same error with
mappings like this.
