Writing you own WCS controller command

Steps involved in writing you own controller command are

1. Writing controller command interface 

• As this is  your first command it is best if you stop your server
• Open WCS developer and  go to Java EE view
• In the Enterprise Explorer view open WebSphereCommerceServerExtensionsLogic and right click on src folder and create a new interface (new > Interface)
• In the inftrace creation wizad fill in below details and click finsh:
• Name:  HelloWcsCmd 
• Package: com.developernotes.wcs.commands
• Extended interface:   com.ibm.commerce.command.ControllerCommand  (Click on add button and search for ControllerCommand)
• In the interface class HelloWcsCmd.java enter below code:

// default implement class
  static final String defaultCommandClassName = 
   "com.developernotes.wcs.commands.HelloWcsCmdImpl";

2. Writing controller command implementation class.

• In the Enterprise Explorer view open WebSphereCommerceServerExtensionsLogic and right click on src folder and create a new java class (new > Class)
• In the class creation wizad fill in below details and click finish:
• Name: HelloWcsCmdImpl
• Package: com.developernotes.wcs.commands
• SuperClass:  com.ibm.commerce.command.ControllerCommandImpl (Click browse and search for  ControllerCommandImpl)
• Interface:  com.developernotes.wcs.commands.HelloWcsCmd (click add search for you interface and add)
• In the implementation  class HelloWcsCmdImpl.java enter below code: 

@Override
public void performExecute() throws ECException {
 super.performExecute();
 System.out.println("Hello WCS");
}

3. Adding Struts entry

• Open struts-config-ext.xml in Stores web-project in Struts Configuration File Editor
• Go to Action Mappings tab in Struts Configuration File Editor 
• Under  Actions Mappings section, click Add button. Delete the default path value(default is /action1) and enter /hellowcs for the path value. 
• Under Action Mapping attributes, enter com.ibm.commerce.struts.BaseAction in the Type attribute and  in Parameter attribute enter com.test.wcs.commands.HelloWcsCmd . The parameter attribute contains  interface name of the logic/java class that we need to be executed.
• Save struts-config-ext.xml  
• Restart your server so that the status changes take effect [Apply Struts changes with out server restart]
4. Adding controller command in the command registry (optional)
• You don't need to do this this to make your command work. Command registry is used when you need to specify which implementation the interface class/command should call for a particular store. 
5. Setting up  access control for a controller command
• Create a file HelloWcsCmdACPolicy.xml enter below xml in this file.
• Place the file in  xml\policies\xml directory which you can find with in you WebSphere Commerce Developer installation directory.  
• Run acplod  [ Acpload command ]

Start you server and go to http://localhost/webapp/wcs/stores/servlet/hellowcs . In the console if  you can see the message "Hello WCS" your first command ran successfully.

Acpload command

1. To run the access control policies you need to use acpload.bat in  \bin directory with in you WebSphere Commerce Developer installation directory.  
2. To run acpload if you are using default WCD (Derby data base)
1. Open command prompt and go to bin directory 
2. Run acpload ACPolicyfilename.xml
3. To run acpload if you are using DB2 or Oracle 
1. Open command prompt and go to bin directory 
2. Run acpload <your database name> <your Db user name>  <your Db user password>   <ACPolicyfilename.xml >  <DB schema name (normally it will be same as  your database user name)>
3. check the acpload.logs and make sure there is no errors.
