根据日志，我设法使用rest-api创建事件流定义。
[2012-08-22 08:48:57,287] INFO {org.wso2.carbon.databridge.streamdefn.cassandra.datastore.CassandraConnector} - Saving Stream Definition : StreamDefinition{streamId='labit.stream-0.0.3-67a2ed14-ece6-4d98-a904-0dde7892c3a9', name='labit.stream', version='0.0.3', nickName='null', description='LONG and BigINT Test stream', tags=null, metaData=[Attribute{name='myTimeStamp', type=LONG}, Attribute{name='source', type=STRING}], correlationData=null, payloadData=[Attribute{name='fibonacciNumber', type=INT}]}
但是当我尝试发布活动时..
[
{
"payloadData" : [1] ,
"metaData" : [1340279541606, "labittest"]
}
]
..使用rest-api，它会引发异常。

另一方面，我可以从Java代码向同一个流发布一个事件。
dataPublisher.publish(labitStream, new Object[] { 1340279541606L, "labittest" }, null, new Object[] { 1 });
我使用的WSO2 BAM2版本是从wso2bam-2.0.0-BETA.zip中提取的版本。
所以问题是：如何使用rest-api发布具有long类型属性的事件？
