The problem was on the solr installation.
Do NOT use ubuntu packages to install solr or sorl-jetty. Do NOT download the solr php integration if you are going to install it on Drupal 7(I think it should be on the README). -Thanks pwolanin for helping me to fix it!

As suggested by pwolanin, I did the installation without packages, I did not use tomcat/jetty. I used the start.jar included in solr, making things simpler. I did a multicore installation that looks to be working fine.

Many guides on the internet and drupal.org instructs to install the solr-php library. As it was included in the module from D6 to D7 version I think it should be cited there. Also, from beta5 to beta6 it changed the faceted blocks, now you need to download the Facet API module to make it work (it also needs to be cited on the README).
