Can't fetch any rows using SOLR DataImportHandler from DB

Question

Have a simple test database setup for my first attempt at indexing DB data using the SOLR DIH. Unfortunately, I get the following result from full import each time:

<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">15</int>
</lst>
<lst name="initArgs">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</lst>
<str name="command">full-import</str>
<str name="status">idle</str>
<str name="importResponse"/>
<lst name="statusMessages">
<str name="Time Elapsed">0:0:2.187</str>
<str name="Total Requests made to DataSource">1</str>
<str name="Total Rows Fetched">0</str>
<str name="Total Documents Processed">0</str>
<str name="Total Documents Skipped">0</str>
<str name="Full Dump Started">2011-03-06 21:30:07</str>
<str name="">Indexing failed. Rolled back all changes.</str>
<str name="Rolledback">2011-03-06 21:30:07</str>
</lst>
<str name="WARNING">
This response format is experimental.  It is likely to change in the future.
</str>
</response>

my solrconfig.xml has the following requestHandler defined:

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
  <str name="config">data-config.xml</str>
</lst>
</requestHandler>

my data-config.xml contains the following:

<dataConfig>
<dataSource type="JdbcDataSource" 
          driver="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:8889/Dev1" 
          user="root" 
          password="***"/>
<document>
<entity name="business_profile" 
        query="select business_id,business_name,address1,address2,city,state,zip from business_profile">
</entity>
</document>
</dataConfig>

schema.xml field definition:

<field name="business_id" type="int" indexed="true" stored="true"/>
<field name="business_name" type="string" indexed="true" stored="true"/>
<field name="address1" type="string" indexed="true" stored="true"/>
<field name="address2" type="string" indexed="true" stored="true"/>
<field name="city" type="string" indexed="true" stored="true"/>
<field name="state" type="string" indexed="true" stored="true"/>
<field name="zip" type="string" indexed="true" stored="true"/>

If the total requests to datasource displays '1', does that mean the JDBC driver is configured properly and it's a possible MySQL permissions issue at that point or not necessarily?

I've played with the DIH dev console trying to get something back, but it's always 1 request and 0 rows which makes me think it's JDBC or the mySQL permissions. I've ruled out the DB name, port #, & user/pass, but perhaps the JDBC driver is setup incorrectly..?

Thanks

Here's what I'm getting from the solr log

Look at the SOLR logs, it would print the stacktrace whenever indexing fails.
