Configuring the business object configuration file

The business object configuration file defines how to load the data into the database. In this file, you specify the implementation classes for your Data Reader, Business Object Builder, and Business Object Mediator components. You also specify the attributes and properties for these components.

About this task

Sample business object configuration files are provided for different component objects within the component-specific directories in the following directory:

utilities_root/samples/DataLoad
WCDE_installdir/samples/DataLoad

Procedure

Create a copy of a sample wc-loader-object.xml file and rename the file.
For example, copy the wc-loader-catalog.xml file within the Catalog component directory.
Open the new business object configuration file for editing.
Specify your data reader implementation class.
1. Find the <_config:DataReader> element.
2. Set the className attribute value.
  The value of this attribute specifies the class name for the data reader. You can specify the provided class,
  - com.ibm.commerce.foundation.dataload.datareader.CSVReader
  - com.ibm.commerce.foundation.dataload.datareader.XmlReader
  However, if you customize the data reader, you can specify your implementation class. For more information about configuring the data reader, see:
  - Configuring the CSV data reader
  - Configuring the XML data reader
  For example, the following snippet configures the data reader:
```
<_config:DataLoader 
  className="com.ibm.commerce.foundation.dataload.BusinessObjectLoader" >
  <_config:DataReader 
    className="com.ibm.commerce.foundation.dataload.datareader.CSVReader" 
    firstLineIsHeader="true" useHeaderAsColumnName="true" >
</_config:DataReader>
```
Specify your business object builder class.
1. Find the <_config:BusinessObjectBuilder> element.
2. Set the className attribute value.
  The value of this attribute specifies the class name for the business object builder. The two implementation classes that are provided are:
  - com.ibm.commerce.foundation.dataload.businessobjectbuilder.BaseBusinessObjectBuilder for component-based business objects
  - com.ibm.commerce.foundation.dataload.businessobjectbuilder.TableObjectBuilder for table-based objects
  For more information about configuring these business object builders, see
  - Configuring the component business object builder
  - Configuring the table object builder
Optional: Configure the Data Load utility to exclude any columns that you do not want the utility to load data into or change.
To exclude columns, you can define a column exclusion list within the <_config:DataLoader> element. For more information, see Configuring a column exclusion list.

Save and close the file.

As an example, the following snippet configures the business object configuration file for loading attribute dictionary attribute allowed value data:
