Solr DataImportHandler with SQL Server

Question

I'm having a problem getting Solr to talk to Microsoft SQL Server via the Microsoft JDBC Driver. I have the handler registered in solrconfig.xml:

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
  <lst name="defaults">
    <str name="config">C:\Program Files\Apache Software Foundation\Tomcat 6.0\Solr\conf\data-config.xml</str>
  </lst>
</requestHandler>

In data-config.xml I have a data source and a document defined:

<?xml version="1.0" encoding="UTF-8" ?>
<dataConfig>
  <dataSource type="JdbcDataSource" name="ds1"
    driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
    url="jdbc:sqlserver://localhost;databaseName=myDB;responseBuffering=adaptive;"
    user="xxxx"
    password="xxxx"
    readOnly="true"
  />

  <document name="members">
    <entity name="member" datasource="ds1" pk="id"
      query = "select 
        MemberID as id,
        UserName as userName,
        FirstName as firstName,
        LastName as lastName,
        Birthday as birthday,
        PrimaryEmail as primaryEmail,
        PersonalStatement as personalStatement
        from member"
      transformer="DateFormatTransformer">
      <field column="Birthday" name="birthday" dateTimeFormat="yyyy-MM-dd" />
    </entity>      
  </document>
</dataConfig>

The columns are fairly irrelevant - I just wanted to start with a few items, including a date column. The Solr schema.xml has some fields defined:

<field name="id" type="tlong" indexed="true" stored="true" required="true" /> 
<field name="userName" type="text" indexed="true" stored="true" />
<field name="firstName" type="text" indexed="true" stored="true" />
<field name="lastName" type="text" indexed="true" stored="true" />
<field name="birthday" type="tdate" indexed="true" stored="true" />
<field name="primaryEmail" type="text" indexed="true" stored="true" />
<field name="personalStatement" type="text" indexed="true" stored="true" />

When I attempt an import, the log shows an exception building the datasource:

I've read the FAQ and documentation, looked at as many sources as I can find, and I just can't get past this error. What am I doing wrong? The error "Unable to read: dataimport.properties" appears to be shown any time there is any issue with the configuration. I can't find my mistake.

It seems that the datasource is not recognized in the entity declaration because the proper attribute to use is dataSource, not datasource
