I. Servlets Advantages over ASP are tabulated.
| Feature | Servlet | ASP |
|---|---|---|
| Platform-independent | Servelts are platform-independent being written in Java. | Works on Windows, a Microsoft product, only. |
| Java Benefits | Servlets are written in Java and can take advantage of OOPs, robustness and most important garbage collection in code development. | Written in VBScript (or JScript), a Microsoft product, only. |
| Performance | Because Servlets are compiled earlier before execution, they are of high-performance. | Because VBScript is intrepreted on client request on-the-fly, ASP comparatively of less performance. |
| System crash | Servlets (JVM) never crash the host system. | ASP on Windows NT 4.0 (when a kernel-mode driver fails) can crash entire system. |
| Easier Maintenance and scaling | As Java is structured, it is much easier to maintain and build large-sized applications and can be scalable along with other J2EE modules. | As ASP is written in a scripting language, difficult to manage complex and big applications and less scalable. ASP is good for smaller applications. |
| J2EE advantage | Servlets can take advantage of JMS, transaction management, resource pooling, JNDI, ORM support (like Hibernate) and MVC implementation etc. | ASP cannot enjoy all these built-in features of Servlets. |
| Data persistence | Servlets can have access to persistent data through JavaBean components. | ASP have no data persistence across pages. |
| Virus attack | Many Web servers, where Servlets are working, are on UNIX and thereby they are very secure | ASP works on Windows and Windows can get attacked easily with virus from Internet. |
| Communicty and tool support | As Servlets are developed through Java Community Process, Servlets can be run on different Web servers like Tomcat (free software) or Weblogic or JBOSS etc., where the client can be choosy. | Works on IIS (Internet Information Server) server, a Microsoft product, only. |
II. Disadvantages
Java (being object-oriented) has high-learning curve than ASP (being object-based).
