Subject: Re: query regarding Input Validation

Hi Saddiq,
-- siddiq

Thanks for your help....
I am not able to understand meaning of below line
You can achive this by creating an separate file for each method
...do you mean that i should create separate action class for each method
or you mean to say separate validation file for each method of an
action class...

--- Separate validation file for each action name speicifed in the struts.xml , 
http://docs.huihoo.com/webwork/2.2.6/Validation.html



By your suggestion, I need to create multiple action mappings in
struts.xml for each of the method of the action class....

Its not with the method of the actin class , its the action name what is been defined in the
strust.xlml
-- For example if you have an action class user
UserAction.java
public class UserAction extends action {
     public String addUser(){
        return success;
    }
    public String modifyUser(){
        return success;
    } 
}

struts.xml
<action name="addUser"  class="UserAction" method="addUser">
    <result name="success'>somejsp.jsp</result>
    <result name="input">otherjsp.jsp</result>
</action>

<action name="modifyUser"  class="UserAction" method="modifyUser">
    <result name="success'>somejsp.jsp</result>
    <result name="input">otherjsp.jsp</result>
</action>

Validation files naming convection .

UserAction-addUser-validation.xml -- when user click on adduser --this validation file is
going to be invoked
UserAction-modifyUser-validation.xml -- when user click on modifyuser -- this validation file
is going to be invoked.

http://docs.huihoo.com/webwork/2.2.6/Validation.html

Note : this validation files need to be in the same package with action class.

Can we avoid this multiple action mappings by wildcard characters.....?

-- Yes we can avoid multiple action mapping. 


Please suggest your opinion.....

I am also waiting for some reply on Question 2 I have asked on earlier mail....
 Question 2 ?

Thanks

Gaurav
