| Base of difference | Servlets | JSP |
| Speed | When we compare Servlets with JSP Servlets run faster than JSP | But when we say about JSP it is slower than Servlets as it will takes time to compile the program and convert into servlets. |
| Complexity | Writing code in Servlet is very hard than JSP | To write code in JSP very easy then Servlets. |
| MVC architecture | When we say about MVC architecture, Servlets works as a controller. | JSP works as a view for displaying output when we say about MVC architecture. |
| Data Processing | Servlets is mainly used when there is more data processing is involved. | We use JSp when there is no involvement of much data processing. |
| Custom Tag | When we say about custom tag writing there is no facility avaialble in Servlets. | In JSP we can easily build custom tags that can directly call Java beans. |
| Language | Servlet is mainly a Java code. | JSP is mainly HTML base code. |
| Protocol | Servlets will accept all the protocols request including HTTP. | On the other hand JSP will only accept HTTP request. |
| Service() Method | We can override service() method in Servlet. | In JSP we can not override the service() method. |
| Session Management | When we say about session management in Servlet by default session is not enable and to enable this we need to do that explicitly. | In JSP session management is enable automatically. |
| Logic | In Servlet we need to implement both business and presentation login in single file. | In JSP business logic is split from presentation logic using JavaBeans. |
| Modification | Modification in Servlet file is a time consuming due to recompiling, reloading, and restarting the server.
| JSP modification is fast, as you just need to click one refresh button. |
