Tenho um site em execução em uma instância do Amazon EC2 e estou tentando fazer com que o Solr faça interface e funcione com o banco de dados que estou usando. Sou capaz de usar a interface administrativa e obtive os arquivos xml de exemplo indexados, mas sempre que tento importar uma das minhas tabelas de banco de dados, recebo o erro

SEVERE: Exception while processing: gamelydb document : SolrInputDocument[{}]:org.apache.solr.handler.dataimport.DataImportHandlerException:
 Unable to execute query: SELECT * FROM league Processing Document # 1

Aqui está o meu arquivo data-config.xml. Também adicionei o dataimporthandler ao arquivo solrconfig.xm

<dataConfig>
  <dataSource type="JdbcDataSource"
              driver="com.mysql.jdbc.Driver"
              url="jdbc:mysql://www.mysite.com/mydb"
              user="root"
              password="mypassword"/>
  <document>
    <entity name="mydb"
            query="SELECT * FROM league">
       <field column="id" name="id" />
       <field column="leaguename" name="leaguename" />
    </entity>
  </document>
</dataConfig>

Alguma idéia de por que isso está acontecendo? E informe-me se precisar esclarecer alguma coisa.

Então mudei um pouco o URL e removi o 'http: //' e esse erro pareceu desaparecer. No entanto, nenhuma das informações parece ser pesquisável pelo administrador. Agora, existem alguns arquivos no diretório de dados (_1.fnm, _1.frq, ...). Aqui está o que o solr imprime no log.
