How can I add a default value to a spring-based form:input control?
I am using spring-form.tld tag library for binding my user input controls to command object.


I tried to modify the above code to:

But the form:input does NOT allow "value" attribute.

Please advise.

You can define this property by editing command object in the controller.
To be more exact I need to see your controller method.

I got the issue resolved by initialing command object properties with default values.

I'm currently having the same problem and the solution provided seems ok but that implies everytime the default values will be the same.
I need to show values from a database in the corresponding inputs. The purpose is to allow the user edit the values previously captured.
Is that possible? What do you mean by editing the command object?

Thanks in advance

"editing the command object" captures your case very easy (in opposite to post author's solution).
I show you how controller should look in spring-3.0 (using annotations).


Controller method has an argument bill that will be passed to a form (it's called command object).
You can prepopulate it here.
As controller is a usual spring bean you can easily autowire other beans to it and prepopulate with some values from business-logic.

Thanks a lot.

Now thats using annotations. Im new to spring so Im having hard time using them, will try that solution though but that takes me to another question do i need to name my method 'createGET'? im trying to understand the order in which the methods are called so that one is called before the jsp is rendered? I was thinking one of the following colud help me initApplicationContext
onBind
initBinder

thanks again

You haven't used Annotations in Java before, they aren't a Spring specific thing.

Anyway, it is much better with Annotations because your classes can now be true POJOs with no classes to extend or interfaces to implement from an api or framework., So no need for initApplicationContext, onBind or initBinder requirements.

Due to the fact I started using SimpleFormController for most parts of my project I decided not to include Annotations (I'm not sure you can even mix them but I guess that would ruin the meaning). So for now I managed to modify the bean defalut values by using a formBackingObject http://maestric.com/doc/java/spring/mvc and it works

You're right, while looking at samples, tutorials and the documentation I've seen that Annotations is the way to go with Spring so I guess that's the next thing on my to do list
