Spring MVC controller Form

[Steve Palmer]

Folks, Long time viewer first time poster here on Javaranch. My issue is I am submitting a form that hits the method attached below. I am successfully fetching the value sent from the JSP form. My problem is to make this value available to another class. Lets call this class Sample.java.
How do I make the values submitted from the JSP form available to class Sample.java and keep it there for use until the user logs out.
I tried adding a public String variable in Controller method shown below and then creating an instance of Controller in Sample.java to get the value but it always returns a null.
Help much appreciated.

 @RequestMapping( value = "abc/xyz/dummyPath.html", method = RequestMethod.POST )
    public String processThisValue( @ModelAttribute( "myValues" ) MyBean myBean,
            ModelMap model)
	{
    	 
    	log.info("I am in my controller.........");  
    	
    	String valuePassed = myBean.getValuePassed();

		log.info("Prints fine here: " + valuePassed);
    	
    	return "";
    }

Simple enough if you know how to set and get from the session. Check out Spring document and other sources for more info...


In your controller use the following:

Example,

getSession().setAttribute() & getSession().getAttribute()

Tommy, thanks for the reply. I was just thinking about doing the session way. Session attributes are accessible in a regular java class?

[Tommy Delson]

Yes, Session attributes are accessible in your Controller which is your regular Java class.

I am sorry I should have said it clearly... Regular Java class which is not a Controller.

If you use MVC then your regular class is your domain class, you only access and use session in your Controller. Domain object is an Entity or your Model where you declared your members such as instance variables and getter and setter methods.

Seem like you're new to Spring and not understand how MVC works, refer to Spring doc for more details and learn how MVC works.
