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.

You can access a global action forward on each jsp or action class. A local action forward can only be accessed by the assigned action class. What is a action mapping? The action mapping is the heart of struts. It managed all actions between the application and the user. You can define which action will be executed by creating a action mapping. The diagram show you, how the application server manage the request of the index.jsp or a non existing action mapping. In the first step we create a new action mapping. Open the struts-config.xml, you will find it in the folder WebRoot/WEB-INF. Right click in the outline window on action-mapping. Choose Use Case default and Action Type Forward. The Forward Path is the welcome page /jsp/index.jsp In the second step you create a global act...
