To get any type of substantive response, you'll need to provide a lot more detail than that. Please read this for more information.

o im sorry for not being clear earlier. well i have a servlet cartDetails that gets a cartid from the DB and stores it in a customer bean. i also have a jsp page that is supposed to call this servlet. when i add stuff to the cart it does that successfully because i checked the DataBase but when i click on show cart i dont see the items that were added

So when you say "print" you mean to display on-screen rather than on a piece of paper?

[ronald zook]

i apologize if my response came accross in the wrong way. i wasnt trying to be arrogant in any way. well right now im getting the following error when i click on the shoppin cart link

Error: Cannot find any information on property 'TableData' in a bean of type 'bean'

[Bear Bibeault]

You're not giving us much to go on.

First, I ask again, by "print" you mean display on-screen, right? Usually "print" means to send to a printer.

Secondly, how are you declaring and accessing the bean? Does it have properly formed bean accessors? Such as getTableData()?

If so, the property name would be "tableData".

o im sorry. by print i mean send to the browser i.e display on screen. i have the proper gets and sets in the bean. why should the property name be lower case?

[ronald zook]

the property name in the jsp is tableData but im still getting this error

Cannot find any information on property 'TableData' in a bean of type 'bean'

hi ronald,

why don't you post relevant parts of your code (.jsp and bean)

Cannot find any information on property 'TableData' in a bean of type 'bean'

This looks fishy.
Your useBean declaration looks OK but it's trying to cast your customer to an object of type "bean".

Have you restarted this app since the last time you recompiled your classes?
Also, are you sure that the latest version of your JSP is being used?
What container are you using?
