Re: how to add table in storage-conf.xml

[Chris Goffinet]

0.3 only supported 1 table. Trunk and upcoming 0.4 has multi-table  
support.

firstly thanks Gasol and Michael, my problem solved.
sencedly how to i solved?
i find in default storage-conf.xml <Tables> has a <Table  
Name="Table1"> tag,and i add a new <Table Name="users"> tag,then i  
invoke with 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.)
	at org.apache.cassandra.service.Cassandra 
$insert_result.read(Cassandra.java:5072)
	at org.apache.cassandra.service.Cassandra 
$Client.recv_insert(Cassandra.java:303)
	at org.apache.cassandra.service.Cassandra 
$Client.insert(Cassandra.java:276)
        at com.chinaren.alumni4.cassandra.CClient.main(CClient.java:33)

and then i delete <Table Name="Table1"> tag in storage-conf.xml,  
then i invoke with up program is ok. cassandra prohibit more than  
one <Table> tag?

columnPath in 0.3 used to be defined as a composite string
"columnFamilyName:columnName" or  
"columnFamilyName:superColumnName:columnName"

Now in trunk/0.4 it is defined as a ColumnPath struct/object that can
be instanced as Gasol has written below.
