i use apache-cassandra-incubating-0.3.0.jar and not find  ColumnPath class.

ColumnPath cp = new ColumnPath("content", null, "name");
client.insert("users", key_user_id, cp, "Chris Goffinet".getBytes("UTF-8"), timestamp, false);

don't use trunk,unless you know what you are doing.

i add table tag in storage-conf.xml:

 <Table Name="users">
     <ColumnFamily ColumnSort="Name" Name="content"/>
 </Table>

and then invoke by below program:

client.insert("users", key_user_id, "content:name", "Chris Goffinet".getBytes("UTF-8"), timestamp, false);

and then throws exception:

InvalidRequestException(why:Column Family content is invalid.)
