ServletContext

How to get the ServletContext in Struts 2

1) ServletActionContext - Get the ServletContext object directly from org.apache.struts2.ServletActionContext.

import javax.servlet.ServletContext;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
 
public class CustomerAction extends ActionSupport{
 
 public String execute() throws Exception { 
  ServletContext context = ServletActionContext.getServletContext(); 
  return SUCCESS; 
 } 
}

2) ServletContextAware - implements the org.apache.struts2.util.ServletContextAware interface.

When Struts 2 ‘servlet-config’ interceptor is seeing that an Action class is implemented the ServletContextAware interface, it will pass a ServletContext reference to the requested Action class via the setServletContext() method.

import javax.servlet.ServletContext;
import org.apache.struts2.util.ServletContextAware;
import com.opensymphony.xwork2.ActionSupport;
 
public class CustomerAction 
    extends ActionSupport implements ServletContextAware{
  ServletContext context;
 
 public String execute() throws Exception {
  return SUCCESS;
 }
 
 public void setServletContext(ServletContext context) {
  this.context = context;
 }
}
