I am developing a java ee application and I have created a dictionary project.

I only want to use the MAXDB - not the MS SQL Server. I think I have to change the data source in the application server to MAXDB.

How can I do that?

I am getting the following error message:

Application has a weak reference to resource SAP/JPA_DEFAULT with type javax.sql.DataSource but the resource is not available and the application may not work correctly.

I hope you can help me.



in my book example: They are writing the following..

But where do I have to put this xml file?

<?xml version="1.0" encoding="UTF-8"?>
