Property names are case sensitive. Your property name is "userEmail"
not useremail
public void setUserEmail(String userEmail)
<s:textfield key="useremail" /> (wrong)
The params interceptor will try to call setUseremail(String). As this
doesn't exist userEmail is null.
<validators>
<field name="useremail"> (wrong)
The validator will be calling getUseremail() to see if the value has
been set correctly. As this getter doesn't exist validation fails.
Remember validation is of the object, not the form

Hi,
I have just started learning Struts-2. I am using sruts2-blank
application
on Tomcat server. I added email field in login file. Problem I have is
validation is failing. Even if I put email address in email field,
framework
comes back with the error message from my validation.XML file(Email field
required).
I see following error on the server...
SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
catched: Error setting expression 'useremail' with value
'[Ljava.lang.String
;@8cd4db'
I would appreciate any help on this.
