正确使用DIH中的ContentStreamDataSource

Question

Solr documentation briefly mentions that ContentStreamDataSource can be used as a data source in the DIH config. No any other guidelines of hints are provided, so I expected that the following config is enough.

<dataConfig>
<datasource name="streamsrc" type="ContentStreamDataSource" loggerLevel="TRACE" />
<document>
    <entity
        stream="true"
        name="streamxml"
        datasource="streamsrc1"
        processor="XPathEntityProcessor"
        rootEntity="true"
        forEach="/books/book"
        transformer="TemplateTransformer" >
            <field column="load" template="some static payload"/>
            <field column="b_title" xpath="/books/book/name"/>
    </entity>
</document>
</dataConfig>

and the following request will perform the procedure of full import taking the data source from the stream of the current request:

curl -X POST \
http://xxx.yyy.zzz/xmlimport \
-H 'content-type: multipart/form-data; boundary=----    WebKitFormBoundary7MA4YWxkTrZu0gW' \
-F 'stream.body=<?xml version="1.0" encoding="utf-8"?>
<books>
 <book>
 <name>NAME1</name>
 </book>
 <book>
<name>NAME2</name>
</book>
</books>' \
-F commit=true \
-F debug=true \
-F clean=false \
-F command=full-import

However Solr raises exception during processing:

Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException: org.apache.solr.handler.dataimport.DataImportHandlerException: No dataSource :null available for entity :streamxml Processing Document # 1 at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:271) at org.apache.solr.handler.dataimport.DataImporter.doFullImport(DataImporter.java:424) at org.apache.solr.handler.dataimport.DataImporter.runCmd(DataImporter.java:483) at org.apache.solr.handler.dataimport.DataImportHandler.handleRequestBody(DataImportHandler.java:183) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:195) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2503) at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:711) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:517)

Any suggestions for implementing that scenario ?

SOLVED

The problem was in the improper name of the xml tag for the data source. It is case-sensitive, so the correct name is <dataSource... instead of <datasource... .
