Explicit casting from Userdefined type to a java.lang.Object

Hello All,

Actually in my program I am casting userdefined class XYZ to String as

String mystr = myXYZ.toString();

where myXYZ is an object of type class XYZ, which gives no errors, and I send this string to an another program and in that program I am trying to retrieve the type XYZ from the String which I am not able to do, I am trying to do it similar to

Object myObject = (Object)new XYZ();

but getting an error

Invalid cast from java.lang.String to XYZ.

On the whole the things which I am doing are fine or am I doing something which shouldn't be done?

Please help me out.

Thanks

Sarada.

First, you should ask yourself WHY you really want to do this. But, if you absolutely had to, you could create your toString() method as said before that would list the values of ALL the attributes of that instance, and then you could create a static method in that class that would create an instance of that class based on the info in that String, but it is VERY sloppy code.

Tell us.. what exactly are you trying to do?

To be clear with what I am doing ,

I have a userdefined class with 3 attributes, and I want to create a session object with this class as a value, but as setSession() of HttpSession takes the String as a parameter, I want to convert my class to a String and pass it to setSession() of HttpSession and then convert back my string to my userdefined class when I retrieve the session object using getAttribute() of HttpSession. I guess this makes my question clear.

One more question, is it possible to set the value of a session with a userdefined object.

Thanks,

Sarada
