Re: [digester help] How two construct a Object without a defaultConstructor?

[robert burrell donkin]

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.

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.

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.

Simon

Hi All:
  I want to config the connection factory with a xml file, and want to

parse the file with digest. But the
org.apache.commons.dbcp.DriverManagerConnectionFactory
has not default constructor,
How can I do this?

this java file has two contructor

public DriverManagerConnectionFactory(String connectUri, Properties

props) {

        _connectUri = connectUri;
        _props = props;
    }
    public DriverManagerConnectionFactory(String connectUri, String

uname, String passwd) {

        _connectUri = connectUri;
        _uname = uname;
        _passwd = passwd;
    }

and my xml file like this
<connnection-factory>
  <connection-uri>jdbc:tset:fasdf</connection-uri>
  <properties>
    <property key="fdaf" value="fdasf"><property>
    ................
  </properties>
</connection-factory>

the class DriverManagerConnectionFactory has no public getter and
setter.


Thank u!

IMCaptor
Best Regards
