1. System I (AS400) Login
You will need to develop Login procedures for your web applications. This short section describes how to do this for System I machines.

2.  System I Login Resources
To develop your Login procedure, you will need the following:
Login Page
Java Class to authenticate through an AS400Object
Success failure logic
This workshop will describe all of these resources.
You can find a complete, working PIF solution in the attachments:
As400authentication.zip
EGL JSFHandler
Function authenticate()
Call to Java Class
If successful
forward to next page…
AS400Authenticate (Java Class)
Create new AS400Object
Invoke Authenticate Method
Return success/failure indicator

3.  System I Login Resources – Java Class
In the src folder, create a new Java package, named: as400Security
Then create a new Java Class, named: AS400Authentication
Note that this snapshot is taken from a different project and workspace.
You can add the resources into EGLWeb
As long as the Java package and class names match
package as400Security;
import java.io.IOException;
import com.ibm.as400.access.AS400;
import com.ibm.as400.access.AS400SecurityException;

public class AS400Authentication {
static AS400 as400Object;
public static void setSystemName(String systemName) {
as400Object = new AS400(systemName); }
public static int authenticate(String username, String password)
int intValue = 0;
boolean returnValue = false;
try
returnValue = as400Object.authenticate(username, password);
catch (AS400SecurityException ex1)
intValue = 0;
catch (IOException ex2)
if (returnValue)
intValue = 1;
return intValue;
public static String getUserId()
return as400Object.getUserId();

4.  System I Login Resources – Login Page – EGL Code
In the \WebContent\ folder, create a new Web page named: TestSecurity.JSP
From the page’s EGL code, add the statements in the Notes section of this slide.
Study the comments – in particular, note:
externalType declaration
Call through externalType to Java class for AS400 authentication
// Nov 19, :25:33 AM - EGL V7.0 Migration
package jsfhandlers;
import com.ibm.egl.jsf.UIViewRoot;
handler TestSecurity type JSFHandler {onConstructionFunction = onPageLoad,
view = "TestSecurity.jsp", viewRootVar = viewRoot,
cancelOnPageTransition = YES}
password string; //Logon Password
username string; //Logon ID
aS400 AS400Authentication; //ExternalType to a Java Class for authentication
//Note that the Java Class is: AS400Authentication.java
viewRoot UIViewRoot; //used for JSF Component Tree access
Function onPageLoad()
//syslib.setRemoteUser ("EGL4RPG", "EGL4YOU" ); //Login to the iSeries
//iseriesd.dfw.ibm.com
End
function authenticate()
rc int; //Return code for authentication call
forwardLabel string; //Next page
//assign the name of your host System i machine (ping-able) address
aS400.setSystemName("iseriesd.dfw.ibm.com");
//Call the Java Class through the as400 ExternalType, passing UID/PWD
rc = aS400.authenticate(username, password);
if (rc == 0) //0 is a bad return code from the System i
setError("Invalid User");
else
forwardLabel = "NextPage";
forward to forwardLabel; //You are logged in
end
externalType AS400Authentication type JavaObject
{JavaName = "AS400Authentication", PackageName = "as400Security"}
static function setSystemName (systemName string in);
static function authenticate (username string in, password string in) returns (int);

5.  System I Login Resources – Login Page – JSP Page
From Page Designer:
Create a page header (Login Page)
Drag an HTML Table on to the page. Make it: 1 row/1 column/100% width
From the Table’s properties, Horizontally align the row: Center
From Page Data:
Drag the UserName and PassWord fields onto the page
Make them both input fields
Drag the authenticate() function on to the page – where it will become a Submit Button
From Page Designer
Feel free to change the table’s color (the picture above, uses a custom color: #ddaaaa
To add a true password field:
Select and delete the default password control
From the Enhanced Faces (JSF) Components drawer, drag an: Input – Password control into the table
From Page Data, drag and drop the password field on top of the input – Password JSF control

package jsfhandlers;
import com.ibm.egl.jsf.UIViewRoot;
handler TestSecurity type JSFHandler {onConstructionFunction = onPageLoad,

aS400 AS400Authentication; //ExternalType to a Java Class for authentication

End
function authenticate()
rc int; //Return code for authentication call
forwardLabel string; //Next page
//assign the name of your host System i machine (ping-able) address
aS400.setSystemName("iseriesd.dfw.ibm.com");
//Call the Java Class through the as400 ExternalType, passing UID/PWD
rc = aS400.authenticate(username, password);
if (rc == 0) //0 is a bad return code from the System i
setError("Invalid User");
else
forwardLabel = "NextPage";
forward to forwardLabel; //You are logged in
end
externalType AS400Authentication type JavaObject
{JavaName = "AS400Authentication", PackageName = "as400Security"}
static function setSystemName (systemName string in);
static function authenticate (username string in, password string in) returns (int);

6.  System I Login Resources – Next Page
From the \WebContent\ folder, create a new page named: NextPage.jsp
Using Page Designer:
Add any page heading text, or image you’d like 
Here we’ve saved an image from the IBM site into our project (\WebContent\ folder), and dragged it on to the page.
From Project Explorer
Right-click over TestSecurity.JSP and run the page on the server
Userid: EGL4RPG
Password: EGL4YOU
