Reaching external IP from SAP WAS

[former_member187977]

dear all

Using a web dynpro application, I am trying to integrate to a external payment agency. From my Java code, I try to connect to the external payement agencies server. The connection does not go through well. My SAP WAS JAVA is based on HP UNIX platform. Please let me know if some settings need to be done on the server machine such that external IP becomes reacheable from my Java code.

thank you !

Hi,

Did you try to telnet the external payment agency server from your Portal server and verified if that is reachable.

If that is reachable, check the connection properties (Host name or IP Address of the External Payment Agency Server maintained in your application) once again.

Also, usually in such cases, you need to get your Portal server added to the External Payment Agency's firewall and hence please ensure if that has been added.

To be honest, there could be several reasons for not being able to launch the payment gateway page and hence you'll have to work with your network team and the payment gateway vendor team to look out for the communication issues.

Also, try to read the HTTP Traffic with the help of your network team for troubleshooting.

The above points are just few potential reasons which you can look up to and the actual reason could be something else as well

dear Anurag

1. telnet is not working

2. connection properties are fine in the app as I am able to connect to payment agency when trying the same java code from my laptop

3. portal server is added in agency's firewall

4. network started a trace on the proxy server but could not see any log generated there means the request is not reaching till proxy server from the portal server. It means something is wrong at portal server

I am trying to reach payment gateway server over https protocol. I suspect that port 443 at portal server's firewall is not open. Hence I shall try to get that opened and try connecting again. Let me know if someone knows how to open portal server's firewall's port for https communications.

thank you !

So, as you've stated the issue is with the communication between your Portal server and the payment agency server.

If there is a test payment agency server that can be accessed over http protocol, please try to reach that from your portal server and check the outcome.

Also, as the code is working from your laptop, telnet must be working from your laptop. Check the same and then troubleshoot with your BASIS / Network team why it is not working from Portal server.

BR,

Anurag
