Re: struts 1.1 validation problem / question
Hi Victor, thanks for you reply. the lookupdispatchaction does not really solve my problem, since handling the different actions is not the problem. the problems is the validation of the input fields for the different action. i need different validations depending on the value of the userAction html form value. thanks, Andreas On Sunday 16 November 2003 10:51, Victor wrote: Oi Andre, Tries to verify the LookupDispatchAction class, this class allows to manage diverse actions in simple Action and in this way you can better manage its validations with the Validator.

Re: struts 1.1 validation problem / question
Hi Andreas,
i think the best way is to write your own
validate() method in your action form. There you
can easily check the value of the userAction attribute
and depending on that the other attributes.
example:
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
ActionErrors errors = new ActionErrors();
if (getName().length() 1) {
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(form.error.name.required));
}
return errors;
}

Subject: struts 1.1 validation problem / question
Hi,
i have a small problem / question concerning the struts 1.1 validation.
i have a jsp form that has the following input fields :
id
name
password
userAction
Depending on the userAction value (can be 'show' or 'save') i need to
validate only the id (when userAction is 'show') or the name, password
and id (when the userAction is 'save').
i have one form that contains the 4 properties (with getters and setters)
and an action class that handles the show and the save action.
the problem that i have is the validation. as far as i understand the
docuemtneation it is not possible to validate a property only when
another property has a certain value. in other words it is not possible
to tell the validator to skip validation of a property when another
property
has a certain value.
or am i mistaken ?
how can i solve this problem ? do i need 2 forms and action to handle the
different userActions or is there another way ??
Thanks in advance,
Andreas

Re: file upload
i've not used dynaforms with fileupload so if that is the problem I couldn't say. you could try it with a normal formBean. However as the problem is trying to set a formfile using a string it looks like the problem could be in your jsp. have you set the enctype like below, html:form action=/blah enctype=multipart/form-data and the form property using html:file rather than html:text html:file property=pb_file/ goodluck, c On Friday 14 November 2003 13:38, sairam manda wrote: Hello Sir, I am new to sturts .

RE: NoClassDefFoundError in custom validator
Ok I figured out a way to make it all work ...
The solution ended up being to put all the commons jar files in the root of
the ear, and add them to application.xml as java modules. Looks like it was
indeed a classloader issue then ... which would lead me to think that this
is a bug. No reason why Struts shouldn't be able to do all of the
reflection, especially since this is hardly pushing the envelope. Any
thoughts?
cheers

Subject: NoClassDefFoundError in custom validator
I added the commons validator to my Struts implementation. The
out-of-the-box stuff is working just fine. However, I added the following
custom validator:
public class BarnmanValidator implements Serializable {
public static boolean validateEmailAddress(Object bean, Field field) {
[etc, etc, etc]
When this one is about to be invoked, I get this exception (as
root cause of
a servlet exception):
java.lang.NoClassDefFoundError: org/apache/commons/validator/Field
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:1647)
at java.lang.Class.getMethod0(Class.java:1893)
at java.lang.Class.getMethod(Class.java:976)
at
org.apache.commons.validator.Validator.validateFieldForRule(Valida
tor.java:4
01)
the validator def:
validator name=email.unique
classname=com.springwell.barnman.validator.BarnmanValidator
method=validateEmailAddress
methodParams=java.lang.Object,org.apache.commons.validator.Field
msg=errors.email.duplicate
/
the form def:
form name=register
field property=emailAddress
depends=required,email,email.unique /
field property=password1 depends=required /
field property=password2 depends=required /
field property=firstName depends=required /
field property=lastName depends=required /
/form
If I omit my custom validator everything works fine.
the commons-validator.jar is in my war file's WEB-INF/lib, and there seems
to be no problem locating org.apache.commons.validator.Validator
(as you can
tell from the stacktrace). Only thing I can think of is that it's a
different classloader trying to load the Field class through
reflection? Any
known solutions to known problems?
thanks in advance,
Rob

Redirecting after logon...
Some of my pages need the user to be logged on before they can be viewed, so I have cobbled together some simple behaviour in my Action superclass that forwards them to a logon page. Now, I need to send them back to where they were originally trying to go before I redirected them to logon. I have a couple of questions banging around in my head: 1. Should this redirection be performed by my RequestProcessor class or by my Action superclass? 2. After they have logged on (in LogonAction), I need to return an ActionForward object that takes them back to where they were trying to go originally before I forced them to logon. However, I don't know how to construct an ActionForward that contains everything it needs (for example, what if their original request was a POST containing FORM data, or was a URL like /action/blah?id=123a=bc=d... I want to preserve and forward this info.) 3. I would have thought that nearly every web app would need this behaviour, but both my struts textbooks give mickey-mouse examples, and I can't find anything on the web that looks remotely like a real-world example. Does anyone know of any real examples or advice that they would care to share?

How to forward without redirect from action?
I have an action that does the following:
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
request.setAttribute( testing, This is a test );
return new ActionForward( mapping.getInput(), false );
}
And I have a jsp page that has the following:
%= pageContext.findAttribute( testing ) %
The problem is the jsp page always prints null and the url is never that of
the action, always that of the page. This means the action is always
redirecting to the input page no matter what I set the redirect variable in
the ActionForward to be. How do I forward to the input page without
redirecting?
Here's my action mapping:
action-mappings
action
path=/home/feedback/Email
type=org.app.struts.action.EmailAction
name=feedback
validate=true
input=/home/feedback
/action
/action-mappings
If you have any ideas or need more info to help out, please let me know.
Thanks,
Eric

ExceptionHandler
Hi, I am trying to use the exception handling from default struts ExceptionHandler. I declared this inside a action tag in struts config.xml : exception type=br.com.tatil.tatilj.exception.FaseJaExisteException key=tatilJ.exception.faseJaExisteException path=tiles.erro / 1- I was always getting the white screen. So I put the input property in the action tag. It started going to the input I declared, but what I wanted was to go to the path declared above (tiles one). 2- Beside, I get: [ServletException in:/componentes/mensagens.jsp] Cannot find bean error in any scope' .

Re: Redirecting after logon...
In article [EMAIL PROTECTED], [EMAIL PROTECTED] says... You could do that... or you could do it the J2EE way, decleratively without any coding, letting container do it that way: Thanks for the reply Vic. I can see how that would be the way to go if I were starting from scratch. Unfortunately, I am using a framework that has its own repository for users/roles and I don't think I will be able to coerce it into operating within the J2EE Realm/LoginConfig model. Assuming that I have to build my own infrastructure to handle this, do you have any more thoughts? I already have code that recognizes the user isn't logged on and redirects them to logon... I am just missing the step that sends back to where they were originally going.

ProcessBeanBase subclass
Hi,
I have a ProcessBeanBase subclass that is my business object.
I implemented a JUnit test to see why I was getting the final Response Cannot create
iterator for this collection' in my browser screen,
and I always fall in that ClassCastException.
Need help to understand why. Tks!
Here is my business object, that extends Empresa that extends ProcessBeanBase :
public class BuscaEmpresasComProjeto extends Empresa{
public final String LEGENDA = Empresas com Projetos.;
public Object execute(Object parametros) throws Exception{
super.execute(parametros);
ResultList list = new ResultListBase(
TatilFacade.getInstance().getEmpresasComProjeto(this) );
list.setLegend(LEGENDA);
return new ProcessResultBase(list);
}
}
Here is the test:
/*
* Test for Object execute(Object)
*/
final public void testExecuteObject() {
/**
* Subclass of ProcessBeanBase.
* Implements execute(Object) method;
*/
BuscaEmpresasComProjeto busca = new BuscaEmpresasComProjeto();
ArrayList c = null;
try {
c = (ArrayList) busca.execute(null);
}
catch (ClassCastException ex){
Assert.fail(Nao conseguiu fazer o cast de Object para ArrayList, vinda de
BuscaEmpresasComProjeto.execute() );
ex.printStackTrace();
}
catch (Exception e) {
e.printStackTrace();
}
Assert.assertTrue( c.size() 0);
Iterator i = c.iterator();
Assert.assertNotNull(i);
}
