How to get/set customized Solr data source properties?

Hi,

I am working on a DataSource implementation. I want to get some customized
properties when the *DataSource.init* method is called. I tried to add the
attributes in the *dataSource* element, but I cannot read it from the
*initProps* object. Either I added the attribute in a wrong element, or I
read the property using a wrong way.

    <dataConfig>
      <dataSource type="com.my.company.datasource"
        my="value" />
      <document>
        <entity name="bankdata" query="test">
          <field column="id" name="id" />
          <field column="col1" name="mycol1" />
...
        </entity>
      </document>
    </dataConfig>

But initProps.getProperty("my") == null.

If the property has a full stop, it is probably going through the
scoped resolver which may be causing issues. I would start with very
basic property name format and see what happens.

Otherwise, it is probably a breakpoint and debug time.

: learned it should work. And this is my actual code. I create this

but you only showed us one line of code w/o any context.  nothing in your 
email was reproducible for other people to try to compile/run themselves 
to see if htey can figure out why your code isn't working.

Hi Hoss,

I reviewed the code from other DataSouce classes as well, that's how I
learned it should work. And this is my actual code. I create this
DataSource for testing my ideas. I am blocked at the very beginning...sucks
:(

	...
:     <dataConfig>
:       <dataSource type="com.my.company.datasource"

My understanding from looking at other DataSources is that should work.

: But initProps.getProperty("my") == null.

can you show us some actual that fails with that dataConfig you mentioned?
