i have a question on formatting the output through <bean:write>. my ActionForms contains all the String datatype variable, even though the value in this varibles may be a date or number. i declared all varibles as string datatype because from the UI when the user enters the date if i won't declare it as a string datatype it need to be keyed in some particular format. if this is the case how can i use 'format' in the <bean:write format="###,###.00"/>
Thanks

You have a couple of problems here.
First, you can't nest a custom tag in the attribute value of a custom tag.
You'll have to put the nested value into either a scriptlet variable or a
scoped attribute, and just emit the value as part of the attribute value.
Second (this will probably go away when you fix the first problem), you're
nesting double quotes inside double quotes. If you have an attribute value
that has to quote something inside the value, then the attribute value needs to
use different quotes than the internal quotes.
