I have develeped a web application developed with extjs 4 for UI and servlet for backend logic. I have not purchased any license from ext js and using the open source license. Many say my source code can be seen. My question is whether the end user can see the UI codings developed by ext js or my servlet codings too?

Servlet code runs on the server side. Unless someone has the access to your server, it is not possible to sneak in to your server side.
Servlet代码在服务器端运行。除非有人可以访问您的服务器，否则无法潜入您的服务器端。
ExtJs is basically javascript and works on client side, hence it may be possible to see the code by a user.
ExtJs基本上是javascript并且在客户端工作，因此可以由用户查看代码。
