Incorrect time zone used in Java web service

Question

I have a JAX-B java web service that I use to update a database. Each row in the updated table is represented by an object similar to the following: -

public class Item {
    private String id;
    private Date startDate;
    private Date endDate;

    public Item() { }

    ...

}

This class is created in a separate program and then passed through SOAP in a message similar to the one below: -

...

<item>
    <id>D001IAAC030</id>
    <startDate>2009-09-17T00:00:00.000+01:00</startDate>
    <endDate>2009-10-01T00:00:00.000+01:00</endDate>
</item>

...

As you can see, due to BST, the UTC time has an offset of +01: 00. However, when the object is sorted on the server (which is also located on my local machine), it returns to GMT and subtracts 1 hour from the date.

Can you tell me how I can: -

• Set my Glassfish server to the correct locale so that dates are recognized by BST.
• Tell me how I can intercept marshalling at the end of the web service so that I can set the time zone myself before the date is set.

TIA

Answer 1

, Date () / UTC/GMT. , , Date.toString() JVM ( Calendar). ( JDK.)

, ,

Date now = new Date();
System.out.println(now.toString());
System.out.println(now.getTime())

- GMT ​​/UTC.

/ Date . :

Date now = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:MM:ss zzz yyyy");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
System.out.println(now.toString());
System.out.println(sdf.format(now));
