Servlet returns “HTTP Status 404 The requested resource (/servlet) is not available” (10 answers)

Closed 2 years ago.

I was following the tutorial on o7planning and got stuck at step 6:

http://o7planning.org/en/10169/java-servlet-tutorial

It's just a simple project that show HelloWorld but for some reason I keep getting 404 error. Detail:

However the Tomcat welcome page showing properly.

Here solutions that I've tried so far (and they are NOT working):

Right-click project -> properties -> Project Facets -> Runtimes -> checked "Apache Tomcat v9.0" -> Apply -> finish.

Server tab -> Right-click "Tomcat v9.0..." -> properties -> switch location -> Choose "Use tomcat installation" on "Server locations" panel.

Problem solved, I've not added the index.html. Which is point out in the web.xml

Note: a project may have more than one web.xml file.

if there are another web.xml in

src/main/webapp/WEB-INF

Then you might need to add another index (this time index.jsp) to

src/main/webapp/WEB-INF/pages/

Hope this helps. From eclipse, you right click the project -> Run As -> Run on Server and then it worked for me. I used Eclipse Jee Neon and Apache Tomcat 9.0. :)

I just removed the head portion in index.html file and it worked fine.This is the head tag in html file
