request.setAttribute
Hi there,
I have small
snip
request.setAttribute(myObejct, o);
...
MyObject o2 = (MyObject)request.getAttribute(o);
/snip
You arent looking up the same attribute that you stored it under. Thats why
you get null!
Try:
MyObject o2 = (MyObject)request.getAttribute(myObejct);
(btw: object is spelt object not obejct)
You are storing it in the request with the name myObejct but trying to
retrieve it with the name o. Use:
MyObject o2 = (MyObject)request.getAttribute(myObejct);

The correct sentence for that is:
MyObject o2 = (MyObject)request.getAttribute(myObejct);
Not MyObject o2 = (MyObject)request.getAttribute(o);
You must get the name of the Attribute and the method returns the instance

Hi Sporak,
The name which you have given your object is myObejct so when you try to retrieve
this object off of the request, you need to do:
MyObject o2 = (MyObject)request.getAttribute(myObejct);

MyObject o2 = (MyObject)request.getAttribute(o);

MyObject o = new MyObject();
o.setObjectName(name);

else System.out.println(o.getObjectName());

Susan,
Here's a response to a different thread with the same type of code block:
http://marc.theaimsgroup.com/?l=struts-userm=103669042429912w=2
I understand this type of approach is used in the example app, but I'd say it's
anything but good practice. In general, if you have an action that's
corresponding to page-2 and save the form-bean under
this name in the appropriate scope.
Is there a way around this issue?
