[Building Sakai] SCORM PLAYER INTEGRATION WITH SAKAI 2.6

OK, so here is a summary of how far I have got. I still can't get the 
integration to work because of a hibernate problem - it's possible there 
is some missing dependency; but I can't identify what that might be. Any 
help appreciated!


1) downloaded Icodeon player2 files (includes pre-built war + build 
files) from Icodeon

2) downloaded rsmart-common + icodeon + icodeon-overlay from rsmart

3) put rsmart-common + icodeon + player2 in my Sakai 2.5 source tree for 
building with maven2

4) fixed up dependencies in rsmart-common (or use 2.5.x branch of 
rsmart-common)

5) ensured osp module was included in main Sakai pom.xml (because of 
dependencies - is OSP really needed?)

6) fixed main pom.xml, added the extra modules (rsmart-common + icodeon) 
and ran maven build for Sakai

7) copied config, maven, and webapps directories from icodeon-overlay to 
player2 directory (overlaying the files in those dirs)

8) added the icodeon-player-2.jar (from 
player2/webapps/player2/WEB-INF/lib/) to our CARET m2 repo (the build 
does not find this jar by default)

9) in player2 maven dir, do a "mvn install -Dmaven.test.skip=true" (skip 
the tests otherwise the build fails with a set of compile failures)

10) 3 jar files are produced under the player2 maven dir:
./vendor-player-plugins/m2-target/vendor-player-plugins-2.jar
./icodeon-player-plugins/m2-target/icodeon-player-plugins-2.jar
./component/model/m2-target/icodeon-player-api-2.jar

These were copied to webapps/player2/WEB-INF/lib/ in the expanded 
player2.war tree and the tree was jar-ed up into a new war.

Starting sakai with the new player2.war in place produced the following 
in the log:
