Date Tag (Data Tag) Example

     

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 <s:date> tag as  shown in the success.jsp page. 

The <s:date name="currentDate" format="dd/MM/yyyy" /> 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. <s:date name="currentDate" nice="false" /> tag formats a date and similarly <s:date name="currentDate" nice="true" /> does not format a date, it is illustrated in our current jsp page.
