Struts2 - Date Tag (Data Tag)

In this section, we are going to describe the Date tag. The date tag allows to format a Date in a quick and easy way. User can specify a custom format (eg. "dd/MM/yyyy hh:mm"), can generate easy readable notations (like "in 2 hours, 14 minutes"), or can just fall back on a predefined format with key 'struts.date.format' in the properties file.
If that key is not defined, it will finally fall back to the default DateFormat.MEDIUM formatting.

Note: If the requested Date object isn't found on the stack, a blank will be returned.

Configurable attributes are :-
1. name
2. nice
3. format

Add the following code snippet into the "struts.xml" file.

struts.xml

<action name="dateTag" class="net.roseindia.dateTag">
   <result name="success">/pages/genericTags/dateTag.jsp</result>
</action>

Create an action class as shown below:

dateTag.java

package net.roseindia;
import com.opensymphony.xwork2.ActionSupport;
import java.util.*;

public class dateTag extends ActionSupport {
  private Date currentDate;
  public String execute() throws Exception{
  setCurrentDate(new Date());
  return SUCCESS;
  }
  public void setCurrentDate(Date date){
  this.currentDate = date;
  }
  public Date getCurrentDate(){
  return currentDate;
  }
}


Now create a jsp page using tag as shown in the success.jsp page.
The date tag formats a Date in a quick and easy way. Here the "format" parameter specify a custom format (eg. "dd/MM/yyyy hh:mm") to follow.
The nice parameter is of Boolean type which decides whether to print out the date nicely
or not. By Default it is kept false which prints out date nicely i.e.
tag formats a date and similarly does not format a date, it is illustrated in our current jsp page.
