Best Practice of URL Redirection in Spring Controllers

Example :

XYZ Class is a Controller and has URL mapping = "parent"
Controller XYZ has method-1 with URL mapping = "first"
Controller XYZ has method-2 with URL mapping = "second"

if you want to redirect from method-1 to method-2, normally we write redirect URL as
     
return "redirect:second";


Here UrlBasedViewResolver does the redirection "relative to current servlet context". It works fine in INTRA calling between methods of controller.But it may surprise when INTER calling between methods of other controllers.

But if you redirect like below

return "redirect:/parent/second";


Here  URL that starts with a slash(/) will be interpreted as relative to the web application root, i.e. the context path will be pre-appended to the URL.It is default behavior in UrlBasedViewResolver.

Benefit of this is that INTER calling between methods of other controllers becomes easier.

Share data between Iframe and its Parent using JQuery

There could be requirement that you have to pass variables values to Iframe from parent or in other scenario you have to pass values from Iframe to its parent.I am going to show simple example of above situation with the help of JQuery.
           Support we have parent HTML page having iframe included like below

<html> <body> <input id="parentValue" type="text" value="I am from Parent !" /> <iframe src="domainurl/relativepath" id="iframe"></iframe> <script> $(document).ready(function() { //code to take value from child iframe var childValue = $("#iframe").contents().find("#childValue").val(); alert(childValue); }); </script> </body> </html> 
        and we have frame code like below
<html> <body> <input id="childValue" type="text" value="I …

Get Browser Name and Version in Javascript

JQuery stopped providing $.browser function after 1.9 release.So you have to write your own code to get know browser and its version.There is not standard procedure or code to achieve this.
But I will show you to get browser name and version of  IE > 6, Google Chrome And FF.

Here we have AGENT to rescue.Every browser has navigation object available in its script.In this object userAgent field contains current browser information.

So you can ask me What is User-Agent?How will it help us?
          As I said earlier it contain browser information.There is not standard to show each information but almost every browser support it.
    There is complicated history behind user-agent variable.But in simple sense we can say that user-agent is used by server side component to get information of client-side browser and its compatibility to page it will going to rendered.So we conclude that this user-agent information is little bit 50% same in all browser.

Why is it(user-agent) 50% s…

Spring Default Limit for Collection and Array is 256

If you are working in Web Application Development then you may stuck or already had ,then you will get mad of getting this error


java.lang.ArrayIndexOutOfBoundsException:Arrayindexoutofrange256
How this error emanates in Spring?

i will explain you with example.Suppose you are adding Values in List in JSP using JSTL tag or other.
This list is in Form(HTML).When you POST this form,In behind Stage,Spring does binding of Object and List if present.

But wait...
In Spring,Default limit for array and collection growing is 256.

Why this limit is Set?

seldom you have to send List size greater than this limit.
Spring has set this limit to avoid notable OutOfMemoryErrors in case of large indexes.

So,than What if i want to set Collection greater than this size?

I had told earlier,spring does binding behind.If we tell spring to increase it's size or set collection size behalf of spring.
You you can do it.

We have initBinder,  in Spring  it is called when spring does the binding mechanism
e.g @Mod…
