Efficient Way of Inserting records into multiple tables

Question

Hello everyone,
Im creating an employee application using struts framework. One of the functions of the application is to create new employees. This will involve using one web form. Upon submitting this form, a record will be inserted into two separate tables. Im using a JavaBean (Not given here) between the JSP page and the Java file (Which is partly given below). Now this Java file does work (i.e. it does insert a record into two seperate tables).
My question is, is there a more efficient way of doing the insert into multiple tables (in terms of performance) rather than the way I've done it as shown below? Please note, I am using database pooling and MySQL db. I thought about Batch processing but was having problems writing the code for it below.
Any help would be appreciated.
