Web Dynpro ABAP

[Former Member]

Hi all,

I am trying to create my first ABAP web dynpro application.

For which I have created a component.

Now when I try to create a view in that component, the view is created successfully but the Layout tab of that view displays the following error:

The page cannot be displayed.

The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.

Can anyone tell me whats going on and what will be the solution?

Your help will be rewarded.

Hi Martini

My problem was with the host file. There was already an entry for my application server in my host file. U find the host file in the following location:

C:\WINDOWS\system32\drivers\etc\

(The above path is correct in case of Win XP, different os may have slightly different path. The name of the host file is "hosts".)

Open the host file in notepad.exe.

My host file was containing wrong entry like as follows:

192.168.0.10 vngsap1

You might be knowing but let me tell u that

192.168.0.10 is the IP address of computer where Web AS is installed and

vngsap1 is a name of the computer where Web AS is installed

The problem is that it wasn't containg the FQCN i.e. including domain name. So added the domain name of my natework as following:

192.168.0.10 vngsap1.vcerp.com

So the syntax is

<IP Add.> <space using TAB key> <Computer Name>.<Domain Name>.com

Try this, if you have the same problem it will work for you also.

Reward if helpful.

bye ~ take care.

Hi Vikranth,

Go to transaction SICF, and search for the application you just created (SAP>bc>webdynpro go to the name space u created)

If the service is inactive, then right click on it and activate it.

Once the service is active you should be able to execute the application.

If the issue still persists then could you pls paste the entire error information you get.

Hi,

You should probably activate the webdynpro service in transaction SICF, please check the documentation about this:
