this is how I debug the codes, and find out something I don't understand so far.
I use mysql db, when codes go into "createGroup", one record is created in the jbpm_id_group table. can someone tell me how the commandService work? what is the "execute" function mean??
hope to learn and heard from you~

appended codes:
identityService.createGroup("management");
public String createGroup(String groupName) {
return commandService.execute(new CreateGroupCmd(groupName, null, null));
}
public interface CommandService {
String NAME_TX_REQUIRED_COMMAND_SERVICE = "txRequiredCommandService";
String NAME_NEW_TX_REQUIRED_COMMAND_SERVICE = "newTxRequiredCommandService";
/**
* @throws JbpmException if command throws an exception.
*/
<T> T execute(Command<T> command);
}
public class CreateGroupCmd implements Command<String> {
private static final long serialVersionUID = 1L;
protected String groupName;
protected String groupType;
protected String parentGroupId;
public CreateGroupCmd(String groupName, String groupType, String parentGroupId) {
this.groupName = groupName;
this.groupType = groupType;
this.parentGroupId = parentGroupId;
}
public String execute(Environment environment) throws Exception {
IdentitySession identitySession = environment.get(IdentitySession.class);
return identitySession.createGroup(groupName, groupType, parentGroupId);
}
}
