Thanks again for the answer. I am not familiar with maven and I find it
difficult to understand how mahout is built. But I am trying hard..
I found the pom.xml file in taste-web folder and tried to modify it, in order
to add the missing dependency but I am most probably doing it the wrong way.
I tried to add this dependency:
<dependency>
<groupId>org.apache.mahout</groupId>
<artifactId>examples</artifactId>
<version>${project.version}</version>
</dependency>
But the command mvn jetty:run-war still fails with the following message:
Missing:
Org.apache.mahout:examples:jar:0.3
I suppose that I have placed wrong values in groupID and artifactId tags..
Can you please tell me what values should I use in order to add the examples
package as a dependency in the recommenderservlet class?
I appreciate your valuable help,
Lef

Yes, please see my last reply. Your new code depends on source code from
several modules of Mahout. You will have to define these dependencies in your
build environment in order for it to access all the necessary code. In
particular you are missing a dependency on the examples module now.
The Maven build pom.xml for taste-web expresses this dependency and so it
works. This is the sort of thing you need to do.
