3. Date Tag (Data Tag) Example
The date tag allows formatting 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 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:
- name
- nice
- format
Add the following code snippet into the
“struts.xml” file. |
|
struts.xml
<action name=”dateTag”
class=”net.javajazzup.dateTag”>
<result>/pages/dataTags/dateTag.jsp
</result>
</action>
Create an action class as shown below:
dateTag.java
package net.javajazzup;
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
specifies 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.
