How to call/execute Custom JAR file in Azure Data Factory

How we can call/execute a custom JAR using Azure Data factory.

Custom JAR includes connecting to an on-prem database.

Is there any option other than VNET?

Hello @Pavithra B ,

Welcome to the MS Q&A platform.

A similar thread has been discussed here.

You can look for using java in Azure functions, and then it would be easy to invoke an Azure function from Azure Data Factory.

Also, you can use a Batch account and Web jobs for this.

Please let us know if you have any further questions.

we are calling onprem services inside .jar files so whats the process to call them ..
Do we need to have VNET created to call the onprem services or without any connection we can call all jar files in Azure functions.

Example :- in jar we are calling oracle Query where it's located at Onprem and creating excel using it. So how to achieve this from ADF

Hello @Pavithra B ,

When you connect to onprem Oracle from the azure function, you will need to create hybrid connection.
The hybrid connection is not supported in Consumption Plan and works with Windows OS for azure function with other plans as mentioned in this article. You need to create the function app under the app service plan.

Once you created the function, please refer this document to invoke Azure function using ADF.
