IllegalArgumentException在Liferay中创建组

Question

我正尝试使用GroupLocalServiceUtil类中的方法addGroup在Liferay中创建一个新组。我根据文档传递参数类型，但是它莫名其妙地抛出IllegalArgumentException。这是我的明码：

ServiceContext sc = new ServiceContext(); 
sc.setScopeGroupId(10); 
GroupLocalServiceUtil.addGroup(11101, "com.liferay.portal.model.Group", 0, 0, "aaa","foo", description, 
      10, null, true, true, sc); 

什么是错？我可以将ServiceContext参数设置为null吗？

更新：我使用的版本是6.1。异常的堆栈跟踪是：

Answer 1

我使用的Liferay 6.1.1，并在GroupLocalServiceImpl.addGroup寻找线276，我可以看到这一点：

if (className.equals(Group.class.getName())) { 
    if (!site && (liveGroupId == 0)) { 
     throw new IllegalArgumentException(); // this is line 276 
    } 
} 

所以，你必须设置site=false和liveGroupId=0。

反正我用这段代码，以创建站点（我再说一遍，的Liferay 6.1.1），它运行完美，只要我还记得;）

GroupLocalServiceUtil.addGroup(userId, Group.class.getName(), 0, "title","description",GroupConstants.TYPE_SITE_OPEN, "/siteFriendlyUrl", true, true, new ServiceContext()); 

Answer 2

• 你肯定url可以为空？
• 你能用Group.class.getName（）替换类名吗？
