Task command接口：

public interface CreateAccountCmd extends com.ibm.commerce.command.TaskCommand {
/**
* The IBM copyright notice field.
*/
public static final String COPYRIGHT = com.ibm.commerce.copyright.IBMCopyright.SHORT_COPYRIGHT;

/**
* The name of this interface.
*/
public final static String NAME = "com.ibm.commerce.account.commands.CreateAccountCmd";

/**
* The name of the default implementation class.
*/
public final static String defaultCommandClassName = "com.ibm.commerce.account.commands.CreateAccountCmdImpl";

...

}

Task command实现类：

public class CreateAccountCmdImpl extends com.ibm.commerce.command.TaskCommandImpl implements CreateAccountCmd {
/**
* The IBM copyright notice field.
*/
public static final String COPYRIGHT = com.ibm.commerce.copyright.IBMCopyright.SHORT_COPYRIGHT;
/**
* The name of the default implementation.
*/
public final static String CLASSNAME = "com.ibm.commerce.account.commands.CreateAccountCmdImpl";

...

public void performExecute() throws ECException {
final String methodName = "performExecute";

ECTrace.entry(ECTraceIdentifiers.COMPONENT_CONTRACT, this.getClass().getName(), methodName);
super.performExecute();
}

...

}

task command被别的代码调用时：

CreateAccountCmd task =
(CreateAccountCmd) CommandFactory.createCommand(
CreateAccountCmd.class.getName(),
storeId);
task.setCommandContext(getCommandContext());
task.setAccountElement(accountElement);
task.execute();
inAccountId = task.getAccountId();
