How to install JSDK on SUN solaris?

[Adameck Collazo]

Hi there!        Sorry, but I'm new in the list and also with servlets, and I have a basic question:   How can I install JSDK in a SUN Solaris 2.7 ultraspark II equipment?   When I try to compile my servlets I get this mistakes:   hello.java:5: Package javax.servlet not found in import. import javax.servlet.*;        ^ hello.java:6: Package javax.servlet.http not found in import. import javax.servlet.http.*;            Thanks in advance!
