Hi !
Thanks for your response.

It’s exactly that: is interpreted (and does not appear in the HTML, passed to PD4ML), but the resulting numeric data format is invalid.

You were right ! It was a problem about the Locale.

But I can’t understand why. Sessions are correctly propagated. I’m sure of this since I use them in my struts action. I use pd4Ml.setSessionId(), I put explicitly the sessionid in the url, I use pd4ml.setCookie("JSESSIONID", sessionId) but nothing works, numeric datas aren’t formatted !

Finally, I ‘ve added the definition of locale directly in my JSP:
<fmt:setLocale value="FR_fr"/> and now it works fine !!!

I don’t understand why I need to do that since Sessions are correctly propagated ….
Anyway, It works fine now.

Thank you very much for your help.
Best Regards,
