Struts2 XML Validation App
Hi,
I am creating my first struts2 application with xml based validation.
However, I am not able to get the validation part working i.e. its not
returning the field error message to UI. Please help.
My code looks like this.
*login.jsp*
<s:form action="LoginAction" method="post">
<s:textfield name="username" label="Login Name"/>
<s:password name="password" label="Password"/>
<s:submit value="Login"/>
<s:fielderror></s:fielderror>
</s:form>
*struts.xml*
<action name="LoginAction" class="com.helloworld.action.LoginAction"
method="execute">
<result name="input">/login.jsp</result>
<result name="error">/login.jsp</result>
<result name="success">/HelloWorld.jsp</result>
</action>
*LoginAction.java*
public class LoginAction extends ActionSupport{
private String username;
private String password;
public String execute() throws Exception {
if(this.username.equals("admin") && this.password.equals("admin"))
return SUCCESS;
return ERROR;
}
public void setUsername(String username) {
this.username = username;
}
public String getUsername(){
return this.username;
}
public void setPassword(String password) {
this.password = password;
}
public String getPassword(){
return this.password;
}
}
*LoginAction-Validation.xml*
<validators>
<field name="username">
<field-validator type="requiredstring">
<message key="user.required"/>
</field-validator>
</field>
</validators>
*LoginAction.properties*
user.required=UserName is required.
LoginAction, LoginAction-Validation.xml and LoginAction.properties all are
in same package. Also I am building my application via ant.
Any help will be appreciated.
Thanks,
Vivek

Hi,
Name of LoginAction-Validation.xml file name must be
LoginAction-validation.xml; so Validation's first character must be
lowercase.
And you should consider to struts form which theme definition used for
it. Look at the
http://struts.apache.org/2.2.1/docs/struts-2-themes.html
Maybe you could try and use annotation based valiton for struts2
rather than using xml definitons.

Your struts.xml is missing a <package> tag -- or did you just not
include it when you pasted?
