使用MySQL的Solr DataimportHandler和作为JSON的URLDataSource

I have this data-config.xml

<dataConfig>
<dataSource name="sql"  type="JdbcDataSource"
              driver="com.mysql.jdbc.Driver"
              url="jdbc:mysql://server/db"
              user="user"
              password="pwd"/>
    <dataSource name="web" type="URLDataSource" connectionTimeout="5000" readTimeout="10000" />

<document name="doc">
    <entity name="artikel" datasource="sql" query="select a.x1,a.x2,b.y1,b.y2 from tab1 a, tab2 b WHERE a.id>0 and a.x1=b.y1"
              deltaImportQuery="select a.x1,a.x2,b.y1,b.y2 from tab1 a, tab2 b WHERE a.id>0 and a.x1=b.y1 id='${dataimporter.delta.job_jobs_id}' "
              deltaQuery="select select a.x1,a.x2,b.y1,b.y2 from tab1 a, tab2 b WHERE a.id>0 and a.x1=b.y1 from tab1 a, tab2 b b WHERE timestamp > '${dataimporter.last_index_time}' and a.shopwgr=b.shopwgr">

        <field column="x1" name="id" />
        <field column="x2" name="bezeich" />
        <field column="y1" name="beschr" />
        <field column="y2" name="keynum" />

        <entity name="artikeljson" processor="XPathEntityProcessor" forEach="/"  url="http://xxx.web.de/dataimport.php" dataSource="web">
            <field column="xx1" name="xx2" xpath ="/xx2" />
    </entity>
   </entity>
</document>

The Request from dataimport.php returns this JSON:

Array (
[0] => Array (
        [xx1] => Text1
        [xx2] => Text2 
        [keynum] => 10003
        [xx3] => text3
        [xx4] => Array

        [xx15] => -1
        [xx16] => 
        [xx17] => Array
            (
                [yy1] => Array
                    (
                        [0] => 10003
                    )

                [yy2] => Array
                    (
                        [0] => 10003
                    )

                [yy3] => Array
                    (
                        [10003] => 18.89
                    )

                [yy4] => Array
                    (
                        [10003] => 0
                    )

                [yy5] => 3
                [yy6] => 0
            )

        [xx18] => 0
        [xx19] => text5
        [xx20] => 19
        [xx21] => 3
        [xx22] => text6
        [xx23] => 0
        [xx24] => Array
            (
                [1] => wrgr01
                [3] => wrgr02
            )))

How i get the Fields at json into Solr? Have one a example with a entity and a PHP generated json that starts with:

Array ( [0] => Array (
    [xx1] => Text1

Can some help me, for the correct data-config.xml?

Your code does not contain any JSON, but print_r()-like output, which you might have inserted to make it more readable, but it makes the question a bit confusing. Moreover, the nesting of the <entity> elements seems mixed up in your extract from data-config.xml.

The more relevant issue is that the pieces in your description/code do not fit together. As you write, the PHP script returns JSON, but you use the XPathEntityProcessor, which operates on XML. As far as I know, the Data Import Request Handler does not support JSON, therefore the most obvious approach would be to actually not send JSON from PHP, but XML.
