your main problem is:
java.lang.ClassNotFoundException: org.hsql.jdbcDriver
be sure the jdbcDriver is in your tomcats (or your applications) classpath!

put the hpyersonic jdbc driver jar in your <tomcat-home>/common/lib

OR

put the hpyersonic jdbc driver jar in your web application (into the 
WEB-INF/lib directory)
