Hello.

I'm using (trying to use) Eclipse for writing my servlets but
I keep getting this strange error: 'HttpServlet cannot be resolve to type'

and it point to this line:

'public class MyServlet extends HttpServlet {'

When I'm using command line javac everything is OK and Servlet works fine
in Tomcat 5.5.7

I'm using jdk1.5.0_02 - 5.0 and Eclipse Version: 3.1.0 Build id:
I20050219-1500

jdk and Tomcat are new (updated today from apache.org and sun.com)

is it my fault? or is it Eclipse's?

what should I do?

thanks in advance

best regards
Luke

Luke,

Have you added the servlet libraries provided by Tomcat to your Eclipse
project? HttpServlet is most likely not in your build path in Eclipse.
You'll need to get the jar that contains that class and add it as a
library to your Eclipse project.

Hope this helps,
- Jeff

I'm not that newbie ;-)

I've create libraries for my servlet project:
/usr/jakarta-tomcat-5.5.7/server/lib and
/usr/jakarta-tomcat-5.5.7/common/lib

Eclipse sees that packages - for example code completition works fine

but there's an error on that first line - the definition of class
extending HttpServlet.

best regards
Luke

OK it was Eclipse error.

I renamed the file to xxx.java and then back to MyServlet.java and error
disappeared.

weird behaviour

best regards
Luke
