Hi Friends,

I installed SAP NW2004s and i assign the username as "SAPUSER" as by default and password as "india123" but when i try to login then it gives me error as invalid name or password.

Please any 1 can suggest me how can i check which is right username and password for login or suggest me by default administration login.

Thanks,

Do you use WebAS default authentication?

If yes check if the user and the password are correct in the UME of the WebAS.

Hi Sravan

I suppose the two pages you have mentioned are two views in your WebDynpro component.

If so,the snippet of code that serves your purpose is given below. It is assumed that you have bound your input fields for username and password to corresponding value attributes in the view context(say userid and pswd). The code should be written in the onActionEvent of your Submit button.

String username=wdContext.currentContextElement.getUserid();

String password=wdContext.currentContextElement.getPswd();

if(username.equals("abc")&&password.equals("abc"))

{

wdThis.wdFirePlugToHome();

}

else

{

wdComponentAPI.getMessageManager().reportSuccess("Invalid Login");

}

Hi Sravan,

Import this package in your login view

com.sap.tc.webdynpro.progmodel.controller.MessageManager;

And if your context attributes are Name and Password.And if you are navigating from LoginView to HomeView. Write the code given below inside your action event.

String login=wdContext.currentContextElement().getName();

String password=wdContext.currentContextElement().getPassword();

if(login!=null && login.equalsIgnoreCase("XXX") && password!=null && password.equalsIgnoreCase("YYY"))

{

wdThis.wdFirePlugToHomeView();

}

else

{

MessageManager msgMgr= (MessageManager) wdThis.wdGetAPI().getComponent().getMessageManager();

msgMgr.reportException("Login failure.Pls check login details",true);

}

Hope this will help you

Hi

It would be advisable to check for Username and password using the way how Jens had suggested. You can configure the UME to create the Users. Here is a link that explains about User Management Engine.

http://help.sap.com/saphelp_nw04/helpdata/en/e5/618a3eacd49076e10000000a114084/frameset.htm

Using a UME would be more standard and easy in this case.

Hope that was helpful.

Hi Sravan,

Just use WebAS default mechanism to protect your application.

Go to Web Dynpro -> Applications -> <your Application> -> edit

open tab "Application properties" and set "sap.authentication" to "true"

If you want to change this login page it is a little bit more complicated but possible.

hi, Jens Rothweiler

i will be more precise

i have a form in my first view so i want to give only one username and passsword to navigate to second view for that where should i write the code

i think it should be written in wdModifyView

Hi Sravan

You could write that code onAction Event of your Submit Button of the login form .

If the user id and password is valid , fire the outbound plug to the next view , if not just so a message "Invalid Login" and do not fire any plugs , so that it stays in the same view.
