Subject Re: Configuring SSL
Date Sat, 21 Jun 2008 13:37:17 GMT
I was thinking at first you might need to specify a custom DB Adapter,
but I think this is the real exception causing the problem:

Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create
PoolableConnectionFactory (Io
exception: Unknown host specified )
Caused by: java.sql.SQLException: Io exception: Unknown host specified
       at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:74)

The Oracle "Unknown host specified" exception is bubbling up and
Cayenne cannot figure out the database adapter to use.  It still seems
like the Oracle JDBC driver cannot connect to your server (the host).

/dev/mrg
