java.lang.ClassCastException: java.lang.Long using Solrj

Hi,

  I'm using solrj (released v 1.3) to add my POJO objects
(server.addbeans(...)), but I'm getting this exception,

java.lang.ClassCastException: java.lang.Long
        at org.apache.solr.common.util.NamedListCodec.unmarshal(NamedListCodec.java:89)
        at org.apache.solr.client.solrj.impl.BinaryResponseParser.processResponse(BinaryResponseParser.java:39)
        at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:385)
        at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:183)
        at org.apache.solr.client.solrj.request.UpdateRequest.process(UpdateRequest.java:217)
        at org.apache.solr.client.solrj.SolrServer.add(SolrServer.java:48)
        at org.apache.solr.client.solrj.SolrServer.addBeans(SolrServer.java:57)

I don't have any "Long" member variable in my java object - so not
sure where is this coming from. I've checked the schema.xml to make
sure the data types are ok. I'm adding 15K objects at a time - I'm
assuming that should be ok.

Any ideas?

Thanks,
-vivek

Thanks Noble. That helped - turned out there was field name mismatch in my bean.

The classcast exception is misleading. It happens because the response
itself was some error response.

debug it by setting the XmlResponseParser
