RE: Displaying mulitpage results

[Néstor Boscán]

Hi Antony

1) Expose two more variables to access first page and last page ( like
nextUrlVar). 

You can use the pages variable and get the first and last page elements to
get the first page and the last page. But It may be interesting to put two
aditional variables.

2) A way to specify the maximum number of page links on the page. For
example if a query returns 500 records and the page size is 10 instead of
showing 50 page links, limit them to a certain number.

With the pages variable you can use the data anyway you like. You can show
all of them or limit the number of pages shown to a specific number. 

Any new features that you can come up is always welcomed.

Regards,

Néstor Boscán

Hi Nestor,
Thanks for putting together the datagrid library. Please see if you can add
these two features in a future release of the library:
1) Expose two more variables to access first page and last page ( like
nextUrlVar). 
2) A way to specify the maximum number of page links on the page. For
example if a query returns 500 records and the page size is 10 instead of
showing 50 page links, limit them to a certain number.

Currently to provide these features I am using scriplets.

Anyway to auto-trim String properties in DynaForms?

[K.C. Baltz]

It would be really nice if I could programmatically indicate that 
certain fields in a DynaForm should be automatically trimmed of 
whitespace.  Is there a way to do this? 

Alternatively, is there a way to get the behavior of the "required" 
validation when using validwhen?  "required" doesn't accept values that 
are nothing but whitespace whereas there's no way to test for this when 
using validwhen.

RE: reality? CoR was Re: Struts or SpringFramework

[David G. Friedman]

Joe,

Your comment on testing CoR (Struts v1.3 or struts-chains) interests me.
How would that be done?  Do you suggest JUnit, TestNG, or something else? sI
looked a little at StrutsTestCase and something about it bothers me, but
what I can't exactly identify.

Er... "mad", not "made".  See, I got so excited about understanding someone
that I forgot to check my syntax (spellcheck missed it, how evil!).

Jokingly: Can StrutsTestCase be used to syntax my grammar before posting to
the list?

Thanks, Vic.  I would suggest that they are not competitors for the
same job under normal circumstances.  IoC might be seen as for a
plumbing strategy (architecture), e.g. Action, RequestProcessor,
ActionForm, etc. as interfaces and CoR for implementation strategies
(application).  I personally would not use CoR where IoC was needed or
where AOP was needed.  I hope I am not being repetitive, but I think
that having RequestProcessor as an interface and using CoR in a
default implementation of that interface would be good.  Am I clear?

RE: Displaying mulitpage results

[Antony Joseph]

Hi Nestor,
Thanks for putting together the datagrid library. Please see if you can add 
these two features in a future release of the library:
1) Expose two more variables to access first page and last page ( like 
nextUrlVar). 
2) A way to specify the maximum number of page links on the page. For example 
if a query returns 500 records and the page size is 10 instead of
showing 50 page links, limit them to a certain number.

Currently to provide these features I am using scriplets.

I would encourage people to look for an architecture that maximizes a
use of the Strategy Design Pattern:

public class DefaultSomeInterface implements SomeInterface {
private Helper helper;

public void setHelper(Helper helper) {
this.helper = helper;
}

public void doStuff() {
 //
 String value = helper.addOrSomething(args);
 //'
}
}

Re: reality? CoR was Re: Struts or SpringFramework

[Joe Germuska]

Obviously it's tough not to be too academic when you're not actually 
cutting code, but the general tack I like to take is to wrap those 
dependencies in classes of my own.  So, in this case:

someDispatchMethod(...) {
(User)request.getSession().getAttribute("user");
you could instead have arranged to use a trivial subclass of 
ComposableRequestProcessor which overrides the "contextInstance" 
method to produce  RicksOwnActionContext which implements the 
ActionContext interface, but which also has this method:

public User getUser() {
  return (User) this.getSessionScope().get("user");
}
Is this a huge gain?  I don't know.  But it's possible.  And it means 
that you could test your class without needing to have a mock 
HttpServletRequest.

if ( user.isSomething() ) {
//call this business method
//if you get something odd back...
//we need to add some flag into scope
reuqest.setAttribute("something",whatever);
else {
  //do the usual
  //call business method
  //look at return and realize we need to set up the next
  //page we go to with something unique bc X condition was met
  //if something
 //so call some other business method to get me this List and pop
 request.setAttribute("neededList", list )
  //else maybe return from business was fine no need to set up request
  //leave
}
For these, I am moving towards defining simple beans which represent 
a use case scope and which, like the example above, provide 
typesafety and encapsulation.  So, instead of sticking two different 
things into the request under different keys, you'd put only one 
(this UseCaseBean), and it would manage the references to any of the 
things your case is likely to need.  (If it's a significant use case, 
then perhaps you'd keep it in session scope instead.)  Then, rather 
than having to do a whole lot of coordination so that everyone knows 
the right names (and sometimes scopes) of attributes, you just ensure 
that the one bean is in the right place at the right time, and 
everything else operates purely on a "need-to-know" basis.

I don't think so. That's just a guess because I have not tried it. I use

Hi Antony

You can't use JSP tags inside the columns. You could use HTML buttons and
input fields with JSTL expressions.

Oh trust me, I'm all for it reducing dependency on the HTTP API and I 
really like the introduction for CoR, 100%. That's why I really like the 
backing-bean concept of JSF. Without Struts having that, yes, I am 
skeptical that you'll end up being that far removed from the HTTP API.

The biggest 'ugliness' in my opinion that I don't like looking at in 
even my own Struts apps is the application logic stuff that gets put in 
my Actions. Somewhere down the line, something comes up and you end up 
having to call different business class methods based on ActionForm 
parameters or session/request parameters.

For example
someDispatchMethod(...) {
(User)request.getSession().getAttribute("user");
if ( user.isSomething() ) {
//call this business method
//if you get something odd back...
//we need to add some flag into scope
reuqest.setAttribute("something",whatever);
else {
  //do the usual
  //call business method
  //look at return and realize we need to set up the next
  //page we go to with something unique bc X condition was met
  //if something
 //so call some other business method to get me this List and pop
 request.setAttribute("neededList", list )
  //else maybe return from business was fine no need to set up request
  //leave
}
We can say we don't like this stuff above and I agree, it's ugly. But it 
does come up. Sometimes I push this kind of stuff off to an intermediate 
class but since this class still is totally struts and HTTP dependent it 
doesn't help me that much. (Again I think using a regular backing bean 
like JSF does goes a long way to making this all much cleaner, but I'm 
not willing to start using JSF full time for anything yet, since Struts 
does the job for me.)

Re: [HELP] Understanding clearly about function of Nested Tags

[Rick Reumann]

Vamsee Kanakala wrote the following on 2/19/2005 1:04 AM:
Now create a web page that has one form that will display all the 
companies (from a companies collection), and the departments 
underneath, and the employees in each department AND you can edit the 
name at any level... you can edit department names, employee names, 
company names, all from one form and submit and have you intial 
collection of companies all properly updated.

Sorry for jutting in, but won't that be a terribly ugly way of doing edits?

ummm yes probably in this case it would be. The point though was to 
exagerate the benefits of how the nested tag is used. At least with the 
nested tag you 'could' accomplish the above quite easily.

As a side note, there are plenty of times when users demand to be able 
to modify multiple items on a single page and hit submit. For example 
think of a fantasy football league where you modify who is starting each 
week. You do it all on one page and hit submit. Plenty of times some of 
the items you are modifying happen to be objects that are nested within 
other objects.

Well, I think you're blurring things here.  When I talk about 
"http-free" components, I'm talking about your business logic, not 
your controllers (actions or commands).
But for most developers, the business logic usually is already self 
contained somewhere else (hopefully we don't still don't see people 
coding JDBC from within their actions:). So for example, in an 
Action method someone might do:
In so far as it is, then they've already achieved the "http-free" 
components.  I'm afraid I don't believe that's as widespread as you 
do, although I'm not saying that no one has figured it out.

What I seem to be seeing in the examples of CoR and Struts is the 
removal of the Action class and instead using a chain of Commands.
Hm.  I don't think many people are really pushing this as "the 
future" or "best practice," but just pointing out that it's 
available.   At least, that's how I feel about it.

This is fine and I like the idea because it does allow for the 
concept of coding pre and post processors without IoC, but I still 
each of them having a lot of ties to the Servlet model. For example, 
maybe before leaving all of the typical CRUD events you need to call 
a populate Command that will populate your Request with some needed 
Lists for drop downs. No longer do you have to remember to make sure 
to include the "populate(..)" method call in each of your dispatch 
methods since you could just add that to the end of the chain.
Well, if we postulate (as ActionContext does) that any 
request/response model will have a few maps for scopes 
(request/session/application) and another for request parameters, 
then you've already insulated yourself against the servlet API.  Now, 
in your test class, you can just make a Map with the parameters you 
want to handle, without having to mess around with MockServletThis 
and MockServletThat.


I'm just wondering if someone could provide some more examples of 
possible real world benefits of the CoR used to replace Actions. I 
can see the standard chain looking like...

-somePreCommand (probably does your initially logging)
-someActionCommand (replaces the meat of your Action dispatch method)
-somePostCommand (maybe ensures some things are put into Req scope)
I'd be curious on seeing some other examples of the possible 
Commands you would likely see in a typical web app? Thanks again for 
any additional light.
I'm afraid we will still have to wait and see.  What I would suggest 
first would be replacing the kind of chaining people currently do 
with requestDispatcher.forward("/to/another/StrutsAction.do") -- say 
to have one command for processing a submitted form and another for 
prepping the page -- but I'm actually thinking I'd prefer to be able 
to hang Commands off of ActionForwards -- the net result would be the 
same, but you'd have less tangled configuration if you simply said 
"always execute this command 'on the way' to this forward" rather 
than having to repeat that configuration for each action mapping that 
might need that page preparation behavior.

Again, I think using commons-chain Commands (or Chains) in place of 
an Action have yet to prove their superiority.  The biggest gain I 
would see out of it would be a further step towards reducing 
dependencies on the HTTP API, which, despite your skepticism ;-) I 
think is a worthy goal in itself.

Re: Struts validator woes : maxLength minLength

[Erik Weber]

A little-publicized feature (ahem) of Struts 1.1 Validator is that arg1 
has to be paired with minlength and arg2 has to be paired with 
maxlength, as I understand it (last I remember this was true). I don't 
know if this has been changed in more recent versions. You are pairing 
maxlength with arg1 in the example posted. Also, I think the var-name 
needs to be "maxlength", not "maxLength".

Check out the datagrid library at 
http://jakarta.apache.org/taglibs/sandbox/doc/datagrid-doc/intro.html

If all you are looking for is pagination, sorting and ordering from the 
database this is a good fit.  It does not have all the bells and whistles 
displaytag has, but is a simple and clean implementation.

The biggest issue I have with the stock displaytag is, you have to stick the 
whole query result somewhere (generally in the users session) to do pagination. 
A very bad idea in my opinion.

Remote struts module interaction

[Ryan julius]

Hi,
Our struts team have decided to separate the main java
/Struts application (/APP1) into 3 independant
modules, each deployed on its own host as follows: 
1- (/webApp1, tomcat1, host1, port1) =>
http://host1:port1/webApp1  (Main entry point :
/webApp1/MainMenu.do)
2- (/webApp2, tomcat2, host2, port2) =>
http://host2:port2/webApp2 (entry point :
/webApp1/login.do)
3- (/webApp3, tomcat3, host3, port3) =>
http://host3:port3/webApp3 (entry point :
/webApp1/StartApp3.do)

We would like to open the login page of /webApp2 from
an action of /webApp1 (for example by clicking the
Menu item "openWebApp2" from /webApp1/MainMenu.do) 

How can we do that?
How can one deploy struts modules on different Tomcat
Containers (by still maintaining interactions between
these modules).

Thanks In advance,

Best regards

Hello everybody,
in my struts application I used to display a table of query results on
one page. Now the results are becoming way too much to display them on
one page. What is the best way to implement a mulitpage result view?
The problem is I have multi-step workflow and I don't want to confuse
the user too much.
Best Regards,
Peter

As far as I know, you may do the paging using . But
then you need to build the traversing and sorting functions youself.

Is there also an option only using struts?

Displaying mulitpage results

[Peter Neu]

Hello everybody,
in my struts application I used to display a table of query results on 
one page. Now the results are becoming way too much to display them on
one page. What is the best way to implement a mulitpage result view?
The problem is I have multi-step workflow and I don't want to confuse
the user too much.

Best Regards,
Peter
