Webdynpro ABAP Application over Internet

[varunride]

Dear Experts,

We are having Webdynpro ABAP application which is working fine locally but we want to run the application over internet.

I find 3 possible steps from which this is possible suggest.

1. via Apache

2. via SAP Web Dispatcher

3. via EP

1. We tried it from Apache but the view is coming as blank on web.

2. No Idea that it can be possible for Webdynpro ABAP application.

3. We don't want to use EP.

Suggest the solution.

Regards,

Varun

Hi Varun,

You can install web dispatcher and route it to the Webdynpro URL. It should be working fine.

Secondly if you already have EP system accessible from internet , you can easily create an iView on Portal and publish on internet.

Hope this helps.

Dear Deepak,

Yes we are having EP but we designed the Webdynpro ABAP application in different manner.

So, we don't want to go in that way.

Suggest the installation & configuration steps with application server for web dispatcher.

Hi Deepak,

Thanks for your reply.

I installed the SAP Web dispatcher with host name SAPWDDISP with port 8900.

Now the problem is coming in connection and configuration of sapwebdisp.pfl.

I am trying to explain you the scenario-

We are having 2 application servers in one of them we maintained the entry as icm\host_name_full = abc.xyz.com; ms/server_port_0 = PROT = HTTP, PORT = 8000

and in default profile rdisp/mshost = defghi; ms/http_port = blank

If my application locally open as-> http://abc.xyz:8000/sap/bc/webdynpro/sap/zzzz

how i redirect to-> http://sapwddisp:8900/sap/bc/webdynpro/sap/zzzz

So, how to maintain sapwebdisp.pfl and host entries?

Regards,

Varun

Hi Varun,

Refer to the configuration of webdispatcher profiles as mentioned in links above.

You need to define the message server host and port entries in the SAP webdispatcher.

When you open the url through webdispatcher, it will route it to SAP message server host and port.

Hope this helps.

In order to affect the URL generation in the backend system, table HTTPURLLOC is used.

Clearly WD can't connect to the HTTP port of the message server. Verify with a browser on the server where WD is running.
