Problems referencing an external project from my jsp - "ExternalClass cannot be resolved to a type"

Question

I inherited 2 JSP projects (tomcat) in my eclipse with common code that is duplicated. I wanted to externalize the duplicate code to common library/project and reference it from both JSP project.

So I did the following:

I created a new Java project "JSP-Common" with the following package "com.mycompany.jsp.common". There I create a class "ExternalClass" with a public "test()" method that returns a string.

in JSP1 project(one of the 2 JSP projects):

1. I added the JSP-Common project to the build path projects tab

2. I added to the jsp file in it the following import:

   <%@ page import = "com.mycompany.jsp.common.*" %>
   

3. I added to the jsp file in the body somewhere

   <% ExternalClass ec=new ExternalClass(); %>
   

After building and publishing the project, I get a "ExternalClass cannot be resolved to a type" error on the line with the instantiation above in my page.

Am I missing something ? Help ?

I want to make it so when I build my JSP1 project it will automatically take the callses from the JSP-Common project.

You have to add JSP-Common project in Deployment Assembly: go to Deployment Assembly page under project properties. Hit Add and select "Project" option.
