Hi.
i have requirement to get Users in LDAP using the realm information give in my application xml file museadmin.xml ( i have attached this file)
i want to get JNDIRealm information , i will use real object to get information like getConnectionURL etc.
I have seen code give below published in site
Server server = ServerFactory.getServer();
//Note, this assumes the Container is "Catalina"
Service service = server.findService("Catalina");
Engine engine = (Engine) service.getContainer();
Host host = (Host)
engine.findChild(engine.getDefaultHost());
//Note, this assumes your context is "myContext"
Context context = (Context) host.findChild("myContext");
Realm realm = context.getRealm();
I want to use this code in my servlet to get JNDIRealm information
i am not able to get the service object , i am getting the NullPointerException in line Service service = server.findService("Catalina");
i have observed that server object is not initialized properly , If i try to print the server.findServices().length it is printing as 0
please some one help me in resolving this problem,
my Servlet Class is below :
public class JNDIRealmServlet extends HttpServlet {
public void service(HttpServletRequest req,HttpServletResponse res) throws ServletException,IOException
{
JNDIRealm realm= (JNDIRealm)getJNDIRealm();
}
public JNDIRealm getJNDIRealm(){
JNDIRealm realm=null;
try
{
Server server = ServerFactory.getServer();
Service ser[]=server.findServices();
System.out.println("length = "+server.findServices().length);
for(int i=0;i< server.findServices().length;i++){
System.out.println("service[ "+i+"] = "+ser[i]);
}
//Note, this assumes the Container is "Catalina"
Service service = server.findService("Catalina");
Engine engine = (Engine) service.getContainer();
Host host = (Host) engine.findChild(engine.getDefaultHost());
//Note, this assumes your context is "myContext"
Context context = (Context) host.findChild("myContext");
realm = (JNDIRealm)context.getRealm();
}catch(Exception ex){
ex.printStackTrace();
}
return realm;
}
}
