MyFaces-Date/TimeZone Issue?

[Amol Chavan]

Hi Ranchers,

I am having an issue with date display in an JSF application
say 31/12/2006 date is being displayed as 30/12/2006
while in DataBase it is stil 31/12/2006.
what may be an issue?
is it an issue related to MyFaces?
I got a solution to set Environment variable:
CATALINA_OPTS= -Duser.timezone = GMT while starting server (Tomcat5.0)
but I can ask client to do this each time at the server start-up.
So how to set up this var for Tomcat as well as JBoss because this variable solves the problem.

Mycode snippet:

<t:inputText styleClass="inputdis" id="txtLrs11" value="#{scheduleBean.datScheduleDate11}" readonly="true">
<f:convertDateTime timeZone="#{policyBean.timezone}" pattern="MM/dd/yyyy"/>
</t:inputText>
---------------

in the above code:
policyBean.timezone is to set timezone to "GMT+10)" bcos in MyEclipse I don know how to set CATALINA_OPTS.
its working fine but then while saving it to DataBase it is saving as 30/12/2006 instead of 31/12/2006.

Please Help me.
Thanks in Advance.....

I wrote my own datetime converter to get around this issue

public class DateTimeConverter
  extends
    javax.faces.convert.DateTimeConverter
{
  public static final String CONVERTER_ID = "au.com.lda.framework.web.converter.DateTimeConverter";
 
  public DateTimeConverter()
  {
    setTimeZone(TimeZone.getDefault());
    setPattern("dd/MM/yyyy");
  }
  
}

Registered my convertor

<!DOCTYPE faces-config PUBLIC
  "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"
  "http://java.sun.com/dtd/web-facesconfig_1_0.dtd">
<faces-config>
<converter>
<converter-id>DateTimeConverter</converter-id>
<converter-class>
au.com.lda.framework.web.converter.DateTimeConverter
</converter-class>
</converter>
</faces-config> 

Usage:

<h:outputText styleClass="dateText" value="#{authorities.effectivePeriod.start}" converter="DateTimeConverter" />

Once again thanks for your help.

To resolve the timezone and date pattern issue, an alternative approach can be found here.

<f:convertDateTime type="date" pattern="dd/MM/yyyy"/>
use this tag .I think it will work

[Tim Holloway]

This is a really irritating property of the JSF datetime converter. It defaults to translating to GMT and the only way to use a local timezone is to either explicitly code the timezone (instead of depending on user locale info) or to use one of the workarounds people have listed above.

Well I was facing the same issue as Amol had, but I removed the timeZone attribute from the <f:convertDateTime /> tag, and guess what I got it on the track.
