This post comes after a long time. I had been really stuck with my project in creating a Single Sign On implementation. I was working with an amazing piece of software, OpenAM, formerly OpenSSO, currently maintained by the Forgerock community.
My setup: I used Tomcat with Mysql and OpenAM 11.0.0 running on Centos
So first things first, install mysql-connector-java for your operating system and you should get a jar file. Here is what I got on my box:
# rpm -ql mysql-connector-java | grep jarNow copy this to your tomcat installation directory. At "$CATALINA_HOME/lib" and restart tomcat.
/usr/share/java/mysql-connector-java-5.1.17.jar
/usr/share/java/mysql-connector-java.jar
