Thank you, Struts!

[Vamsee Kanakala]

Hey folks,
  Well, I have been working with Struts for the past 1 month, and 
though the initial setup was a bit complex (the first time) and 
firguring out the action mappings was tough, I am slowly discovering how 
cool Struts is. Maybe that's why it's so popular. A heartfelt thanks to 
Craig and everybody  who's working on Sturts, you guys make my life 
easier and fun :) The documentation is truly, truly excellent. When I 
get some time, I will surely contribute. You guys rock!

Thanks for everything,
-Vamsee Kanakala.

Re: How to detect Cancel button i pressed ?

Hi Nicolas,
 
Thanks for the response,
 
1)I tried this, but giving me error. Pls would u mind giving some code example ?
 
2)About exception - do u mean to say my own method common to all ? This also if 
u can explain with code example would be of great help. 
 
Thanks once again,

Struts cancel tag uses a magic value that this method will detect

About exception, I used to set a global exception handler that logs

Re: Determining the "original" request URL from within a tile

[Kishore Senji]

1) You can have a Controller (org.apache.struts.tiles.Controller) and
in the "perform" you can get the "original" request url and save it as
a "request" attribute; and the tile can pull that request attribute.
You can specify the controller class for your tiles definition.
Just Before the jsp is rendered the controller is called and so the
tile has the original url available in the request.

2) You can do the same thing in the BaseAction as well. (You can also
have a custom ActionMapping and set the url in the request for only a
set of actions for which a property in the custom ActionMapping is
enabled).

Regarding the request parameters not having the original values; I
don't see any reason why unless you are redirecting.

Re: Edit Form - populate values from database

[Wendy Smoak]

From: "Manisha Sathe" <[EMAIL PROTECTED]>
For Edit what i want is to get the values from database and display it on 
form as default.
What i am doing is ->
1)First calling one action handler getting the values from database and 
putting inside one data bean. Putting that bean inside request scope then 
forwarding to Edit Form
2)Inside Edit form I want to get these values as by default for text box
Rather than putting your bean in request scope, populate the form bean 
before forwarding to EditForm.  The easiest way is with 
BeanUtils.copyProperties() [assuming the property names match].  You can see 
an example of this in struts-example.war.

Using the 'value' attribute (or nested  tag) means that the form 
will always be rendered with the values from the database-- this could be a 
problem if you need to validate the form and re-display the incorrect input.

Struts FormFile and

[Sullivan, Sean C - MWT]

I read the documentation for the  tag

  http://struts.apache.org/userGuide/struts-html.html#file

According to the Struts documentation:

"WARNING: In order to correctly recognize uploaded files, the 
 ActionForm bean associated with this form must include a 
 statement setting the corresponding org.apache.struts.upload.FormFile 
 property to null in the reset() method."

I examined the Struts Upload example application and I noticed that 
UploadForm.java has a reset method.  However, UploadForm's reset 
method _does not_ set the FormFile property to null:

http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/examples/org/apache
/struts/webapp/upload/UploadForm.java?rev=HEAD&view=markup

I have an "upload form" in my application and I want to know if I need
to implement set the FormFile variable equal to null in my form's reset
method.

Thanks in advance.

Determining the "original" request URL from within a tile

[Rick Mann]

Hi. We have a tiles-based webapp. Buried down deep in a tile that gets 
reused in a few different pages is the need to render a link back to 
the current request, with a parameter added. This acts as a switch to 
re-render the page a bit differently.

Unfortunately, request.getRequestURL() reflects the included file (in 
this case, the layout JSP used) and NOT the request in the address bar 
of the browser.

Also available to the tile are SOME of the request parameters (all of 
the names are there, but they have null values, and not the values 
specified in the original request).

What's the best way to get at this "original" information?
TIA,

Yes, totally possible.  Here are some snippets.  :-)
This is what you'd have in your JSP
   
   
   

And this is how I build the list in my classes:
First my Action:
   ArrayList trusts = AssetData.getTrusts(
   getDataSource(request,"trustmaster"), errors);
   if ((assets == null) || (codes == null) || (trusts == null)) {
   errors.add(
   ActionErrors.GLOBAL_ERROR,
   new ActionError("error.resultset.null"));
   }  else {
   // Put our results set in a bean in the session
   session.setAttribute("assets", assets);
   session.setAttribute("codes", codes);
   session.setAttribute("trusts", trusts);
   }
Now my Data:
  public static ArrayList getTrusts(
   final DataSource dataSource,
   final ActionErrors errors)
   throws Exception {
   Connection conn = null;
   Statement stmt = null;
   ResultSet rs = null;
   ArrayList trusts = new ArrayList();
   try {
   conn = dataSource.getConnection();
   stmt = conn.createStatement();
   rs = stmt.executeQuery("select * from trusts;");
  
   // While there are results from our query
   // create the codes bean with the proper
   // values from the database.
   while (rs.next()) {
   trusts.add(
   new LabelValueBean(
   rs.getString("trust_name"),
   rs.getString("code")));
   }
  
   } finally {
   if (rs != null) {
   rs.close();
   }
   if (stmt != null) {
   stmt.close();
   }
   if (conn != null) {
   conn.close();
   }

   }
   return trusts;
   }
Hopefully this helps.

My page in the Wiki mistakenly used CVS where it should have used SVN.
General information about getting Struts from SVN is at

Thus, for features described in the section now entitled "What's in 
SVN", you can just check it out following the above instructions. 
These features will also be in the nightly builds 
(http://cvs.apache.org/builds/jakarta-struts/nightly/).

The other stuff is not in SVN yet, because I don't want to commit it 
until I've put it through at least some testing, and really, there 
are whole ideas in there for which I'd appreciate at least a few 
external confirmations.  But the links in my Apache webdir include 
source and binary forms, so it's about as good as getting it from 
SVN, until you want incremental updates.

Struts-Nested-Tags- Recursing

Hi there,
i am desperate with the nested-Tags.
My Problem: I have a bean A with holding a collection of  bean B. Now i 
would like to get access,  through the collection, to get each bean B.
What do i get? I get each Bean B - instance in the main.jsp. Thats OK! 
But i get only the first bean b - instance in the included tree.jsp and 
i have now idea where i make a mistake. (I read the monky-tutorial and 
googled a lot). Maby u have an idea or can give me a tip.

See the small example:
The main JSP-Page looks like this:
[...]
 
class="Catalog"
scope="session"/>
  
   
   
 come from main: 
 
   
   
[]

The tree.jsp looks like this:
[...]

come from tree: 

[...]
The generated output looks like this:
come from main: bs[0]
come from tree:   bs[0]
come from main: bs[1]
come from tree:   bs[0]
come from main: bs[2]
come from tree:   bs[0]
come from main: bs[3]

Yes, in general your data class has absolutely no need to know about a request, 
so you would normally copy the ActionForm into a Data Transfer Object, and pass 
that to your data layer.
So, you would do this:
DynaActionFrom lookupForm = (DynaActionForm)form;
BeanUtils.copyProperties( lookupDto, lookupForm);
AssetData.addAsset( lookupDto);

This allows you to cleanly seperate the UI from your backend code.

Depends... with the default struts valiation is being done before you get to 
the action class.

Re: struts and testing

If you are looking to test your Actions and Forms outside of the container
then StrutsTetstCase is an excellent choice.  For integration testing you
could use something HttpUnit.

General Action Question

[Brandon Mercer]

Hello Group,
I'm reading an off the shelf book about DynaActionForms and I've got a 
question about best practice stuff.  In this book it says that you need 
to create an Action to work with the info you got much the same as the 
ActionForm you typically use.  In my previous work I've always just sent 
the request into my 'data' class to pull info from and send it into the 
database.  Let me send some code snippets:
  String action = request.getParameter("action");
AssetData.addAsset(request, session, 
getDataSource(request,"trustmaster"));

So if I'm sending the request and working with that, is there a need to 
parse the DynaActionForm using:

  DynaActionForm lookupForm = (DynaActionForm) form;
  String symbol = (String)lookupForm.get("symbol");
Specifically, I want to know if I'm validating the input in both cases, 
and inserting the entire request into the database (after I parse out 
each value) if I need to use the second example to work with 
DynaActionForms.  I'm using multi-page forms, but I insert the values 
into the JSP page for each new page in the wizard.  Thanks for any help, 
as I'm "fresh" with struts. Brandon Mercer

Re: setting image dom properites with

For documentation, try http://struts.apache.org/userGuide/struts-html.html.
styleId is the attribute that you want to be able to access your image 
from JavaScript, I believe.

don't use DynaActionForm. use DynaValidatorForm. if you specify the rules on
validation.xml it will get fired automatically. it will automatically
generate the javascript and even if the user has disabled javascript, before
the action is executed, the RequestProcessor runs the validation on the
server side and if something goes it forwards to the action input.


try a simple form at first... with only one rule and see what happens.

check the files on attachment ;).

  check commons-validator.

RE: accessing bean properties in a jsp

[John McCosker]

Thanks a million for your response,

yea both beans are the same one for client end and the other for server end
when set,
I was wondering if I could get away with the one (the session bean) and use
it also client
end but this flakes on me,



error,

org.apache.jasper.JasperException: An error occurred while evaluating custom
action attribute "value" with value
"${pageContext.session.cookieSession.customerName}": Unable to find a value
for "cookieSession" in object of class
"org.apache.catalina.session.StandardSessionFacade" using operator "."
(null)

however the original problem I got resolved,

in my bean my methods where declared private and not public so now the
original method works fine.

consider setting your CustomerSessionBean values differently.

CustomerSessionBean sb = new

CustomerSessionBean(scv.getCustomerid(),scv.getCustomerName(),
scv.getCfid(),scv.getCftoken());
session.setAttribute("cookieSession", sb);
request.setAttribute("clientSession",sb);


CustomerSessionBean sb = new CustomerSessionBean();
sb.setCustomerid(scv.getCustomerid());
sb.setCustomerName(scv.getCustomerName());
sb.setCfid(scv.getCfid());
sb.setCftoken(scv.getCftoken());
session.setAttribute("cookieSession", sb);

OR (if both beans have the same attributes)

import org.apache.commons.beanutils.BeanUtils;

BeanUtils.copyProperties(sb, scv);
session.setAttribute("cookieSession", sb);

Hopefully this help.

Help with DynaActionForm

[Kalluru Uma. Maheswar]

Hi,

I posted the same question last week but could not get any reply. Can
someone help me please?

 

How do I validate if a field is entered or not using the DynaActionForm?

 

My HTML form has  and  buttons. I want to check
if the user has entered some text in the text field and that he has
selected the radio button.

 

If he has not selected, then show him a error message in the jsp. How to
do this? Do I need to configure any xml file for this? An example would
be great.

 

Thanks

Uma

Re: How to detect Cancel button i pressed ?

[Nicolas De Loof]

You can check for cancel in actions using
isCanceled(request)
Struts cancel tag uses a magic value that this method will detect 
(formbean validation is also skipped)

About exception, I used to set a global exception handler that logs 
exception stack and forwards to a generic error page.

those" but it is a popular approach to paging in JSPs and it is
reasonably lightweight.

Subject: Paging through a collection on a page


HI all

 

Anybody got some sample code that allows me to display multiple pages
from a
collection with next and previous page links. The collection is stored
in
the form class so I'm wondering how easy this is to do. If there are
some
samples on the web I'd be interested in having a look. I'm not
interested in
display tag or one of those. I just need it to be simple and
straightforward.

 

Many thanks

Donie

JAAS would help but that's not Struts specific.

Sessions are unique to individual applications.  In addition, individual
applications are loaded by different class loaders (because they have
different WEB-INF/lib directories), so its quite likely that you'd get
ClassNotFoundException errors even if sessions were allowed to cross the
boundaries.

If you want the "single sign on" type support you are talking about, you
should investigate using your container's facilities for this (for
example, Tomcat supports it), or figure out some way to simulate it,
such as a specially crafted cookie that is recognized by each of your
applications.
