Send mails using On-premise mail server SAP CLOUD SDK JAVA

[alex_aguilera]

Hello,

I'm trying to use a on-premise mail server using SAP CLOUD SDK JAVA. I didn't find any example of how to do it. I know that in case of javascript there's "email-client" (https://sap.github.io/cloud-sdk/docs/js/features/mail-client#on-premise-destination), but for java?

I found this guide: https://help.sap.com/docs/connectivity/sap-btp-connectivity-cf/using-tcp-protocol-for-cloud-applicat...

But it's not a full example, and it's not very clear. Right now, I have a working code that uses Java Mail to send mails using a mail destination (getting destination properties and creating the mail session), but i don't have very clear how to do it with an on-premise destination and use the configured cloud connector.

Could someone share some code example?

Thanks.

The second link is using the javascript mail client.

The first one...i will give it a try, but there's no code available in github.

Thanks for your time.

alex_aguilera You could perhaps use the standard Java Mail Client javax.mail?

Unfortunately, SAP Cloud SDK for Java does not currently support a Mail client.
You could write to our PO dsfas for adding this as a feature request, citing your requirements, but as we are currently working on a new major version of the SDK, I am not really sure if this would be taken up soon.

Ok, I will do it.

As a workaround, do you have some complete example of how to do the same without the mail client? In github for example, i didn't find anything in https://github.com/SAP-samples/cloud-cap-samples-java for example.

Has someone done this first?

Thanks.

We discussed in the team. Unfortunately, the mail client is not planned for the Java SDK at least in 2024. Please check the BTP documentation: https://help.sap.com/docs/connectivity/sap-btp-connectivity-cf/using-tcp-protocol-for-cloud-applicat... which was used as the guide for building the JS SDK implementation.
