Hi Robert: I don't know how to create the rule like u said: "this rule would construct the object not on the element start but at the element end. maybe you might need to create the
child object on the element start in your custom rule so that's available on the stack." Thank u! Best Regards IMCaptor -----�ʼ�ԭ��----- ������: robert burrell donkin [mailto:[EMAIL PROTECTED]. uk] ����ʱ��: 2002��11��26�� 2:40 �ռ���: Jakarta Commons Users List ����: Re: [digester help] How two construct a Object without a defaultConstructor? let's see if i have this right... you have a child object that you need to create before you can construct the father object. the element for the father object enclosed the element( s) which are used to create the child object. if this is the case, then i'd suggest that you look at creating you own object creation rule. this rule would construct the object not on the element start but at the element end. maybe you might need to create the child object on the element start in your custom rule so that's available on the stack. i'll not speculate further but if you do need any help in creating this custom rule, then just post your questions to the list. - robert On Monday, November 25, 2002, at 02:28 AM, IMCaptor wrote: > Thank u for ur help, > But I have another problem, > Because the Attributes I transfer into the constructor are not only > String, but have complicate class, such as Properties. > How do I first construct the child Object, > and then transfer the child Object into the father Constructor. > > > Best Regards > IMCaptor > > > > -----�ʼ�ԭ��----- > ������: Simon Kitching [mailto:[EMAIL PROTECTED]] > ����ʱ��: 2002��11��25�� 4:32 > �ռ���: Jakarta Commons Users List > ����: Re: [digest help] How two construct a Object without a > defaultConstructor? > > > Hi "IMCaptor" (what an unusual name you have :-) > > What you need is the FactoryCreateRule. > > Step 1: > Write a class which extends > org.apache.commons.digester.AbstractObjectCreationFactory. > > Implement the createObject method. > > Step 2: > call method addFactoryCreateRule on your digester instance to set up > the appropriate rule. > > See the javadoc for class FactoryCreateRule for more info. > > Regards, > > Simon > > On Mon, 2002-11-25 at 03:04, ���챦 wrote: >> Hi All: >> I want to config the connection factory with a xml file, and want >> to > >> parse the file with digest.
