ParseException: Could not parse date - Class: java.text.DateFormat

Question

My question is not same as that question about get date from JSP.

Now I have a server using Struts 2.2.1

And the Action is like this:

public class AddMeetingAction extends ActionSupport{

private A a;

@Override
public String execute() throws Exception {
....
}
//getter and setter..  
}

And the class A is like this:

public class A{
    private java.util.Date b;
....
}

When I use Postman to make a HTTP POST request with parameter {"b":"2015-01-01"} to this action, I can get b correctly.

or if I write javascript with jQuery $.ajax(), datatype=json, and get date from bootstrap datetime-picker plugin. It's OK.

but, when others call this action using ios, sending the same string, the server throws exception:

Could not parse date - Class: java.text.DateFormat
File: DateFormat.java
Method: parse

The date conversion is done based on locale. So it is a dup. — Aleksandr M

You need to: 1) change the format sent by iOS, or 2) Create a custom converter. Reading this might help — Andrea Ligios

If you can't modify a sender which is requested a locale specific date, then you can at least add a parameter request_locale to the request. The rest is done by the i18n interceptor. You can read this answer to get more help.

Example:

<action name="someAction" class="com.examples.SomeAction">
    <interceptor-ref name="i18n"/>
    <interceptor-ref name="defaultStack"/>
    <result name="success">good_result.jsp</result>
</action>

Another solution is to change type of the property to avoid conversion errors

public class A{
    private java.lang.String b;
....
}

If you need to convert it to Date you can use DateFormat.
