Classes Not Found Exception

[Laedislaw]

Hey

I am trying to run one of the "showcase" Sample program that comes Spring Social Module. I'm getting class not found exceptions, tried switching to different facebook and linkedin versions with no success.

Class SocialConfig.java

unable to find and import following classes:

import org.springframework.social.facebook.web.Disconnect Controller;
import org.springframework.social.linkedin.api.LinkedIn;


I have the following module versions defined in pom file.

<org.springframework.social.facebook-version>1.0.2.BUILD-SNAPSHOT</org.springframework.social.facebook-version>
<org.springframework.social.linkedin-version>1.0.0.M3</org.springframework.social.linkedin-version>

Note: Versions defined in sample pom file (see below) results in invalid pom file - red cross appears, only disappears when upgarded to above versions.

<org.springframework.social.facebook-version>1.1.0.BUILD-SNAPSHOT</org.springframework.social.facebook-version>
<org.springframework.social.linkedin-version>1.0.0.RC1</org.springframework.social.linkedin-version>

Can anyone spot anything wrong with this .pom file? It seems to have an error but wont indicate where - just red on file.

Problem was to do with the war file. The name should match with sample .pom file

<modelVersion>4.0.0</modelVersion>
<groupId>org.springframework.social.samples</groupId>
<artifactId>spring-social-showcase</artifactId>
<name>Spring Social Showcase</name>
<packaging>war</packaging>
<version>1.0.0</version>

Glad you figured it out. Looking at the times on your posts, it seems you've encountered the same phenomenon that I often encounter: That is, you find the answer yourself within minutes of asking someone else to help you find your problem. I'm not sure why this happens, but I do it all of the time. Either way, at least the problem gets solved!
