[jboss-user] [JBoss Seam] iText pdf generation

Hi people! I'm new with seam and i would like to know how can i set the location for a text in an absolute position in a pdf generated by iText. Something like: <p:text xposition="20" yposition="78" value="#{product.price}"> <f:convertNumber type="currency" currencySymbol="$"/> </p:text> Is there a feature like this? How can i emulate this behavior? I just need to locate some text in a exact place in the coordinate systems. Sorry for the newbie question and the bad english. Thanks in advance Humber
