Thanks Ricardo,
My server's 8080 is behind a firewall, but I can see it and have no problem running other JSP / servlets.
thanks for reminding me about hibernate.cfg.xml
I also realized that I hadn't installed a MySql driver in WB-INF.
However, even though I fixed these two issues, I'm still getting a blank page.
Also, I wasn't sure with settings to use in hibernate:
<!-- settings commented out in original file -->
<property name="connection.url">jdbc:mysql://localhost/xwiki?useServerPrepStmts=false&sessionVariables=sql_mode=''</property>
<property name="connection.username">xwiki</property>
<property name="connection.password">xwiki</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.provider_class">com.xpn.xwiki.store.DBCPConnectionProvider</property>
<property name="connection.pool_size">2</property>
<property name="statement_cache.size">2</property>
<mapping resource="xwiki.hbm.xml"/>
<mapping resource="feeds.hbm.xml"/>
