iReport : to combine format style in a textfield

[Ana Salimi]

I am using iReport version 2.0.5.
My problem is..
I have one text field with the text expression is:
"Name :" +"<style isBold=\"true\" pdfFontName=\"Helvetica-Bold\">"+"Ana Salimi"+"</style>"

The output will be:
Name : Ana Salimi

It looks fine when run in iReport. But if I call this report from web aplication (from .jsp page), the output appear like this :
Name :<style isBold=\"true\" pdfFontName=\"Helvetica-Bold\">" Ana Salimi "</style>"

Please help me.
