3rd time same mistake...And it tells it all in the error message that it is giving...
Now u r saying in createIndexedSlicesQuery(keyspace, ss, ss, ss) that ur values are going to be String, but u r converting both values to ByteBuffers. As shown in https://groups.google.com/group/hector-users/browse_thread/thread/520c5332dedfca4a, pls pass the valueSerializer as BBS (ByteBufferSerializer) 2011/2/17 Raoyixuan (Shandy) <raoyix...@huawei.com> > I modify it as below > > StringSerializer ss = StringSerializer.get(); > IndexedSlicesQuery<String, String, String> indexedSlicesQuery = > HFactory.createIndexedSlicesQuery(keyspace, ss, ss, ss); > indexedSlicesQuery.setColumnNames("full_name", "birth_date", "state"); > indexedSlicesQuery.addGtExpression("birth_date", > longSerializer.toByteBuffer (1970L)); > indexedSlicesQuery.addEqualsExpression("state", > stringSerializer.toByteBuffer("UT")); > > indexedSlicesQuery.setColumnFamily("users"); > indexedSlicesQuery.setStartKey(""); > QueryResult<OrderedRows<String, String, String>> result = > indexedSlicesQuery.execute(); > > It shows the error > > > > The method addGtExpression(String,String) in the type > IndexedSlicesQuery<String,String,String> is not applicable for the > arguments(String,ByteBuffer) > > > > *From:* Roshan Dawrani [mailto:roshandawr...@gmail.com] > *Sent:* Thursday, February 17, 2011 10:54 AM > > *To:* user@cassandra.apache.org > *Subject:* Re: indexedslicesQuery class error > > > > You didn't see the previously given link?
