I am writing a hotel booking website. What is the common methodology used to forward to the selected hotel's website for payment processing so that I can get my commision for making the sale. I am writing my website in spring which shows the user with various choices for hotels and used webservices for getting vacancy information & rate information from each of the hotels. But forwards to the hotel website for actual booking.

Thanks a lot jinal ... it helped a lot... after your post i did some practice on validation and concept is clear now .... but i have only doubt remaining is that whatever validations we configure for client side same validations applies to server side in the configuration files. There is no way in the configuration files, where we can seperate the validations for client side and for server side....

Hi all,

I have few questions regarding validator framework.

1. In struts we can do both server and client side validation so wats the diff btwn two? can i apply all validations at client side?
2. So in the client side validations, <html:javascript formName=" LoginBeanName" /> and <html:form action="LoginAction.do" onSubmit=”return validateLoginFormBean(this);”> are the only tags which i need to add in jsp page.
3. In case of server side validation, can i validate the data from Database? Can i do this? for eg if i want to check whether the user entered fake or existing bank account number?

Please reply... i am very confused ...

Thanks

Yes it was a interview question .... i couldn't hit it .....

Only thing i know is that checkboxes are used to take multiple inputs from the user in case of a form submission...
Can someone explain,
why are HTML checkboxes sometimes problematic for managing true/false values via form submissions?


thanks in advance?
Thanks Everyone Guys

error was resolved actually there were 2 problem one was in the jar files.... i was using 2 versions of a same jar files ..... when i replaced it by using common-logging.jar. jstl.jar, spring.jar & standard.jar files in my lib folder it worked...

Also when i replaced the following the code

<bean id="loginConroller" class="loginFormController">
<property name="commandName" value="login"></property>
<property name="commandClass" value="Login"></property>

<property name="formView"><value>index</value></property>
<property name="successView"><value>success</value></property>
</bean>

<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>


by-


<property name="commandName"><value>login</value></property>
<property name="commandClass"><value>Login</value></property>

<property name="prefix"><value>/WEB-INF/jsp/</value></property>
<property name="suffix"><value>.jsp</value></property>


IT WORKED..... dont know wats d problem!!!... in my opinion both are valid formart in spring....!!!

<bean id="loginConroller" class="loginFormController">

<property name="commandClass" value="Login"></property>
<property name="formView"><value>index</value></property>
<property name="successView"><value>success</value></property>
</bean>

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

<bean id="simpleUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">

public class loginFormController extends SimpleFormController {

@Override
protected ModelAndView onSubmit(Object command) throws Exception {

Login log=(Login)command;

String uname=log.getUsername();

ModelAndView mav= new ModelAndView(getSuccessView());

mav.addObject("uname",uname);
//Add an object to the model.
//modelName - name of the object to add to the model
//modelObject - object to add to the model. May not be null.

return mav;
}

}
