Struts framework question.. thanks..

[Jack Daniel]

Hi e'body

I am pretty new to Struts; I am just working on my first application using STUTS, and in accessing the data Source and working on Databases, I am using an approach something like:

I create a class which implements PlugIn and in the init method i extract the dataSource and put it in the ServletContext..

and in every action class i retrieve it from the ServletContext..

Any thing like a bad design on this approach..??? I think this is ok, but just want to hear about your opinions and want to know how you extract the datasource in Struts framework..

I really appreciate your help in this matter.. thanks again

 
public class AppPlugin implements PlugIn{

public AppPlugin() {
}
 
public void init(ActionServlet servlet, ModuleConfig config) throws ServletException
{

try
{
Properties pr=new Properties();
Class thisClass = this.getClass();
InputStreaminputStream = thisClass.getClassLoader().getResourceAsStream("tester.properties");
pr.load(inputStream);

// Retrieve the data source
 
java.util.Hashtable parms = new java.util.Hashtable();
parms.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
 
// access naming system
Context context = new InitialContext(parms);

// get DataSource factory object from naming system
DataSource ds = (DataSource)context.lookup("jdbc/jdbc******");

ServletContext sc=servlet.getServletContext();
 
sc.setAttribute("PROPERTIES",pr);
sc.setAttribute("dataSource",ds);

}
catch(Exception e)
{
e.printStackTrace();
}
}
public void destroy()
{
}
}
