Issue
Can you tell me how to know which servlet and JSP version am I using ? I use NetBeans IDE 7.1.2 for creating Servlets and JSP.
Solution
You can get the details programatically using ServletContext #getMajorVersion() and #getMinorVersion().
For knowing the JSP version corresponding to the Servlet, you can get details from this Tomcat page.
Below is a brief summary (check Tomcat's corresponding version at the link above):
- Servlet 4.0 uses JSP 2.3
- Servlet 3.1 uses JSP 2.3
- Servlet 2.5 uses JSP 2.1
- Servlet 2.4 uses JSP 2.0
- Servlet 2.3 uses JSP 1.2
- Servlet 2.2 uses JSP 1.1
- Servlet 2.1 uses JSP 1.0
