使用MySQL和Qtjambi的Java客户端 - 服务器应用程序：哪个许可证？

I developed a client-server application in Java. I want to distribute the client side using a zip file containing a jar for my program and Qtjambi jars (LGPL) placed in a different directory. On the server side I have a servlet that communicates with a MySQL database using mysql connector (GPL). Under which licence to I need to release my software? Do I need to make my source code public?I developed a client-server application in Java
