Hi, in a jsp i am displaying some numeric bean properties (all of them are strings) and i would like to know how could i apply a format to them.
The problem is that
<bean:write name="bean" property="p" format="###.##"/>
does not work because it is a string so it doesn�t get formatted, any ideas?

I'd suggest adding a second getter for the field that converts the String to a number. Something like this:

Then in your JSP you can code:
<bean:write name="bean" property="fooAsFloat" format="###.##"/>

Thanks, finally i am using new DecimalFormat(String x).format(float y) to format all the properties before refreshing the jsp

You're working too hard. The format attribute should contain a simple String indicating how to format the number. Change your code to:

Just make sure that the bytes property contains a number (float, double, etc.) rather than a String or other data type. If it doesn't, convert it to a numeric data type in the getter as I demonstrated in a previous post.
It is sorta covered in the JavaRanch Style Guide.
