Developing
The topics in the Developing section describe tasks performed by an application developer.
Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
Management Center framework
The Management Center framework is the foundation for business user tooling. The business objects are defined by the individual components that make up the Management Center. The framework uses those definitions to provide all of the features that you can use to find, create, modify, and delete the defined business objects. If you plan to customize the Management Center, it is important to understand the framework and the components that make up the Management Center.
Predefining the default preferred store name
By default, Management Center does not automatically select a store when a tool is opened unless a business user specifies a default store in the Preferences dialog. A developer can predefine a store to use as the default preferred store for all business users.

Predefining the default preferred store name within the Management Center

By default, Management Center does not automatically select a store when a tool is opened unless a business user specifies a default store in the Preferences dialog. A developer can predefine a store to use as the default preferred store for all business users.

Procedure

Open WebSphere Commerce Developer and switch to the Enterprise Explorer view.
In the Enterprise Explorer view, expand LOBTools > WebContent > WEB-INF > src > lzx > commerce
shell > ConfigProperties.lzx.
Within the ConfigProperties.lzx file, locate this string: <attribute name="defaultPreferredStore" type="string" value="" />.
Add the store name as the value for default preferred store.
For example, if the store name is MyStoreName, specify:
```
<attribute name="defaultPreferredStore" type="string" value="MyStoreName" />
```

What to do next

After you complete your work:

Right-click LOBTools Project; then click Build OpenLaszlo Project to produce an updated ManagementCenter.swf file under the workspace_dir\LOBTools\WebContent directory. This setting is the default environment setting.
Test your changes by viewing them in the Management Center, using this URL: https://hostname:8000/lobtools.
Deploy your changes to your production environment.
