Download certificate for service layer

[former_member260921]

Hi,

I need to call the B1 Service layer from an XS application.

As I understand it this means:

1. Download the certificate for the Service Layer.

2. Set up a Trust Store for the App.

3. Import the Certificate into the Trust Store.

Currently I am using a self-signed certificate.

Are these the right steps?

What is the easiest or most standard way to do step 1 - download certificate.

Will a self signed certificate work or do I need to get an valid signed certificate?

Thanks for any help.

Regards,

Mel

Hi Mel,

You can download the certificate from your browser if you go to https://HanaAddress:50000 and press the certificate box in your URL bar.

Also you can download it from your SLES system by path: <ServiceLayer installation folder>/conf/server.crt.

By default it's /usr/sap/SAPBusinessOne/ServiceLayer/conf/server.crt

I guess it's up to customer what certificate to use. It's not free to issue a valid certificate and if you are going to consume ServiceLayer from XS that will be internal traffic, so I think it won't be a security issue. If you want to call it from front end JS it's another case, then you need to setup CORS and probably provide a normal certificate.

BTW you also can call ServiceLayer by HTTP. Example of a destination file using HTTP (in this case you don't need to setup the truststore):

host = "<YourHanaIP>";
port = 50001;  
description = "ServiceLayer UNTRUSTED!!!!";
useSSL = false;
pathPrefix = "/b1s/v1/";
authType = none;
useProxy = false;
proxyHost = "";
proxyPort = 0;
timeout = 0;

Hi Sergie,

Thanks very much for your response. I was able to download the service layer certificate and import it in to the trust store for my XS app. I restarted the SAP B1 Tools and the Service Layer .I am logged in to the XS Engine.

The Untrusted configuration works but , I am still getting the error "HpptClient request: request failed: SSL requested but no trust store configured" when I tried the secured option.

I am not sure what I am missing. Do you have any other suggestions?

Thanks.

Regards,

Mel

Hi Mel,

Let me advertise my post a bit) I've just published a blog post how to update SAP B1 rates using XS and Service Layer and there is a trust store configuration section there: Post

It's very close to your case so try to go through it firstly. Let me know if you are still confused with how to reach this goal.
