Displaying Message to User

Many the times, we get a requirement of displaying some static message to the user as a support activity.

The message can be displayed as both pre login and post login. Let’s see both the scenarios.

Pre Login Scenario

As the message is to be displayed before the login screen is shown, we need the logon par which is used asthe login module in the portal.

The com.sap.portal.runtime.logon.par is the login module which is used as the logon screen in the portal.

We need to modify this par file to achieve this pre login scenario.

This par file can be obtained in System Administration tab in portal. To obtain this par file, navigate as below:

System Administrator > Support > Portal Runtime > Browse Deployment

Root > WEB-INF > deployment > pcd > search for com.sap.portal.runtime.logon.par file and download it.

Note: To get this par file, we need to have the System Administration role.

The downloaded par file contains the code to modify as per our requirement and save it as logon.par.

Create a Project Using the par in NWDS

The downloaded logon.par file is used to create the project in NWDS. Click on the par button as shown in thefigure to upload the par file.

Figure 1: Import the par file

Let the project is named as PreLogon.

Figure 2: Create the project in NWDS

The umLogonPage.jsp is the initial page which is called whenever the portal link is opened. So we needchange the code in this page.

We need create a temporary JSP file in which the original code of umLogonPage is saved.

For instance we will create a JSP file called umLogonPage_temp.jsp and copy the original code ofumLogonPage.jsp to this.

To create the new jsp page, follow the below steps,

Right click on Portal-INF folder -> new -> other . As shown in the below screen shot.

Figure 5: Name the file

Name the JSP file as umLogonPage_temp.jsp, and create a new JSP page.

Copy the original code of umLogonPage.jsp to umLogonPage_temp.jsp.

As the portal initiates with umLogonPage.jsp, we will put the code which displays the static text as themessage for the user. Find the below code.

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Welcome to Portal</title>

</head>

<body>

<h4>

Welcome

</h4>

<center>

The text which you want to display...

<form name="test" action="/irj/portal">

<input type="submit" value="Go"/>

</form>

</center>

</body>

</html>

By using this code we can display the required text and can redirect the Logon Page once user clicks Gobutton.

Deploy the code by exporting the par file to the portal server and run it.

Once the user clicks on Go button, it will show the logon page.

Post Login Scenario

As the message is to be displayed after the user logs in, we need the portal masthead par. Thecom.portal.navigation.masthead.par is the module which the portal takes the user once he/she logs in.

We need to modify this par file to achieve the post login scenario.

This par file can be obtained in System Administration tab in portal. To obtain this par file, navigate as below:

System Administrator > Support > Portal Runtime > Browse Deployment

Root > WEB-INF > deployment > pcd > search for com.portal.navigation.masthead.par file and download it.

Note: To get this par file, we need to have the System Administration role.

The downloaded par file contains the code to modify as per our requirement and save it as logon.par.

Create a Project Using the par in NWDS

The creation of new project is similar as to that which mentioned in the above pre login scenario.

Let the project is named as PostLogon.

Figure 9: Create the project

The HeaderiView.jsp is the initial page which is called whenever the user is logged into the portal. So weneed change the code in this page.

We need create a temporary jsp in which the original code of HeaderiView.jsp is saved.

For instance we will create a jsp file called HeaderiView_temp.jsp and copy the original code ofHeaderiView.jsp to this.

To create the new jsp page, follow the below steps,

Right click on Portal-INF folder -> new -> other . As shown in the below screen shot.

Figure 10: Name the temp jsp as HeaderiView_temp.jsp

As the home page of portal initiates with HeaderiView.jsp, we will put the code which displays the static textas the message for the user into this page. Find the below code.

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Welcome to Portal</title>

</head>

<body>

<h4>

Welcome

</h4>

<center>

The text which you want to display...

<form name="test" action="/irj/portal">

<input type="submit" value="Go"/>

</form>

</center>

</body>

</html>

To run this code we need to com.sap.portal.navigation.masthead_core.jar and htmlb.jar files into the classpath of the project and copy these files in the lib folder under PostLogon\dist\PORTAL-INF\lib path of theproject as shown in the below screen shot.

Figure 11: Adding jar files

By using this code we can display the required text and can redirect the original home page once user clicksGo button.

Deploy the code by exporting the par file to the portal server and run it.

Output:

Figure 12: Welcome message.

Once the user clicks on Go button, it will show the home page of the user.
