is there any way to pass objects throw http params ?

Hello
say I like to pass object I created in one page say : MyObject obj = new MyObject("1","2","3");
via http params (supmit or post ) to other page . and use it there can it be done ?

pass the object after storing in a HttpSession.getSession().setAttribute("anyname","Myobject");

In the next page (where ever you want to access)
MyObject myobj = (MyObject)HttpSession.getSession().getAttribute("anyname");

ok thanks
tell me please if I use this kind of way to use paramets:

I can access the object[] elements but I way I cant get the object[] length ?
is it good methods to pass objects? if I need to avoid using sessions?

Well, you can pass only string objects via parameters. For your custom objects and other objects, use attributes.

but way this code dont work even if i do :

A request only lasts long enough to return one page.
Then it's gone.
When the user submits the form on that page, a new request is generated.
That new request isn't going to have any of the attributes from the old one.
You either need to save the information in a longer lasting scope (session or context scope) or find a way to serialize that object into a string that can be written to the page as a hidden input field.

ok i see what do you mean by "context scope"

context scope == application scope.

Objects bound to context scope last the duration of the application.

Why are you avoiding session?

no its ok i will use sessisons
one more question when i trying to copy the the contant of the object
to other object im geting error here is my code now and its working fine until i try to copy the object[] to object[]

do i need to use System.arraycopy ? is this the only way?

sorry ignor , i used clone()

Why are you copying/cloning the array?
If you're binding it to session you should be able to work with the same array from both pages..
