Sorry I can not include this file because http://ohloh.org says that this may conflict with another license. In the file JdbcMetaData.java in package com.caucho.jdbc in method public static JdbcMetaData create(DataSource ds), you need to add if ("H2".equalsIgnoreCase(name)) return new H2MetaData(ds); else just before if ("oracle".equalsIgnoreCase(name))
