Hi, I don't speak english very very well, so this is a bit difficult for me to explain, but I'll try ;-) see below ...

I have'nt looked at the beanutils Converter registration, do you have to register a class or an instance? The problem here is that if there is only one instance of your class, and setFormatPattern is only called once, then if there are two request that require the use of your class a the same time, served by different threads, the parse method in your instance of SimpleDateFormat might be called concurrently, so (as it isn't thread save) it might fail. -- To unsubscribe, e-mail: mailto:struts-user-unsubscribe;jakarta.apache.org For additional commands, e-mail: mailto:struts-user-help;jakarta.apache.org

WS You say that the default BeanUtils.copyProperties works fie with WS java.sql.Date, but I find that I still have a problem unless the user types WS in the date backwards-with-dashes (2002-11-06) the way the WS java.sql.Date.valueOf() method wants it. And that's a bit much to expect of WS the users. Sorry, just saw this post from you. Did you get it all worked out? The DateConverter thing I mentioned works great when you register like in the example and yes you have to BeanUtils.copyProperties. You will be able to set the format for however you want the user to enter it (11/06/02,etc) and it will display it back in the same format. Just let me know if you got it worked out, if not I can help. -- Rick mailto:maillist;reumann.net -- To unsubscribe, e-mail: mailto:struts-user-unsubscribe;jakarta.apache.org For additional commands, e-mail: mailto:struts-user-help;jakarta.apache.org
