validation message

[sarah jj]

hi,

i am developing a web application for the first time using
MyEclipse7.0 IDE
hibernate 3
struts 1.1
MyEclipse Tomcat 6
i want to have a <html:form> for my jsp of connection which contains textfields userName, password...and it must invoke on submit the action /userLogin which is already mapped in struts-config.xml there are two possibilities
either to have an other jsp page in success
or to redirect to the same jsp if there are some missing or invalid fields

here my code

messagesRessources.properties

  
# -- Page userLogin--
error.userName.required=Remplissez le champ Username svp \!
error.password.required=Remplissez le champ Password svp \!
error.codeMagasin.required=Remplissez le champ Code Magasin svp \!

userLoginForm.userName=username
userLoginForm.password=pasword
userLoginForm.codeMagasin=code 
 

userLogin.jsp(i just put the code of my form)

 
			<html:form method="post" action="/userLogin">
		
			<span class="sarra">Administrateur : </span> <html:checkbox property="adminis"/><html:errors property="adminis"/><br/>
			<p> </p>
			<span class="bold">Username : </span> <html:text property="userName"/><html:errors property="username"/><br><br>
			<span class="bold">Password : </span> <html:password property="password"/><html:errors property="pasword"/><br><br>
			<span class="bold">Code Magasin : </span> <html:text property="codeMagasin"/><html:errors property="code"/><br>
			 <p> </p>
			<html:submit value="Connexion"></html:submit><br>
			</html:form>
 

userLoginForm(it contains all getter and setter method and here is the validate method)

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {
	
	ActionErrors errors = new ActionErrors();
	
	if( getUserName() == null || getUserName().length() < 1 ) {
		errors.add("username",new ActionMessage("error.userName.required"));
		
	}
	if( getPassword() == null || getPassword().length() < 1 ) {
		errors.add("pasword",new ActionMessage("error.password.required"));
	
	}
	if( getCodeMagasin() == null || getCodeMagasin().length() < 1 ) {
		errors.add("code",new ActionMessage("error.codeMagasin.required"));
	
	}
	return errors;
}
 

finally for userLoginAction it just contains the different mapping values

my problem is instead of having a message error in front of the missing field it just cause an exception as if i add it to validator-rules.xml
please could you help me to display these messages??

[David Newton]

What exception?

[Prakash Mani - Attur]

Validator should work with 1.1.. may be the problem is yours.. It can be forgot to add plugin element in struts-config.xml.. but i should not guess like this.. if you have given us the exception message then it might be more useful..

Also I will tell your requirement..
Use html:errors tag in the jsp file at the start of your html:form tag....
for e.g it may be like this... If this is not the better approach please tell me how to approach it better..

  
<logic:present name="<%=Globals.ERROR_KEY%>">
       <html:errors/>
</logic:present> 
 

Also you can display the errors in the list form by adding the below lines in property file..But some say adding html contents in property file is bad idea, if you too think so use custom tags..

   
errors.header=<UL><font color="red" face="Arial" size="1">
errors.prefix=<LI>
errors.suffix=</LI>
errors.footer=</font></UL>

Apache Tomcat/6.0.13

last night i tried the plug-in in struts-config.xml but always the same exception

  
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
        <set-property
            property="pathnames"
            value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
 </plug-in>
  

and my new messagesRessources.properties

userLoginForm.userName=username
userLoginForm.password=pasword
userLoginForm.codeMagasin=code
   

by the way i tried your solution

  
<logic:present name="<%=Globals.ERROR_KEY%>">  
              <html:errors/>  
</logic:present> 
  

but it invoked an error which is "Globals cannot be resolved" could you please explain what did you mean by adding this tag and what's the problem with it

here is my jsp page if it may help you

[Prakash Mani - Attur]

errors.add("username",new ActionMessage("error.userName.required"));

instead of the above try the below

errors.add("username",new ActionError("error.userName.required"));   

..
also you need not to use GLOBALS ERROR_KEY, simply use html:errors tag in the form.. if you still want to use it import this package
org.apache.struts.GLOBALS

[sarah jj]

thank you so so much
i just put <html:errors/> and change ActionMessage with ActionError and finally it works
thanks again

[Rajesh Vraj]

Hi,

Actionerror instead of action message worked for me.

thanks alot.
