execute SQLServer and MySQL stored procedure from Java

good morning / afternoon / evening at the time you see this post the issue is that I do not know the syntax to call a SQLServer stored procedure from java example

//para llamar a un una sentencia insert/update/delete/select utilizo
PrepareStatement stInsert=con.PrepareStatement("INSERT INTO ejemplo VALUES(?,?,?)");

but how can I do for a stored procedure or what syntax does it have in both SQLServer and MySQL?

Thank you in advance
