Can we host Java report in ms fabric

Hi pallavi_r ,

 

Yes, you can. 

For Java Integration,you can generate reports in Power BI from a Java-based application by leveraging Power BI’s APIs. This involves embedding Power BI reports within your Java application and passing data dynamically.
You can also pull data from your Java application into Power BI using REST APIs or direct database connections.
MS Fabric for Data Integration.

As for Hosting JAR Files, MS Fabric supports custom libraries, including JAR files. You can upload these JAR files to your Fabric environment and use them in your Spark job. Fabric allows you to manage both public and custom libraries, making it flexible for various development needs.
