I do not really know how to translate this for Eclipse but if this was
a stand-alone
Tomcat, the way you describe it above, project1 and project2 (when
deployed) should also
have the class available under their respective
(catalina_base)/webapps/projectX/WEB-INF/classes/ directory (or
/WEB-INF/classes/lib/, if
in a jar). Is it the case ?
Thank you for your answer.
No, it is not the case.
- There are no ".class" files from "project3" under "classes"
directories for the two projects "project1" and "project2".
- I didn't make a ".jar" file out of "project3" because I don't want to
have to do it every time I change the code of the classes in "project3"...
Note - If I do not add "project3" via "Project -> Properties -> Java
Build Path -> Projects" for both projects "project1" and "project2" I
get hundreds of errors. So clearly this is a required setting...
I don't know what is missing...
Thank you for helping me.
Best regards.
