Hello All:
I have a xml file like this
<items>
<item>fdasfdasfd</item>
<item>fvxcvcvxvdasfdasfd</item>
<item>fdasfafdasdasfd</item>
</items>
I want to put the item into a vector,
so i create the rules like this
<digester-rules>
<pattern value="items">
<object-create-rule
classname="java.util.Vector"/>
<call-method-rule pattern="item" methodname="add" paramcount="0" />
</pattern>
</digester-rules>
but I always get a error
java.lang.NoSuchMethodException: No such accessible method: add() on
object: java.util.Vector
why the add(Object o) can't adapt to add(String obj)?
Thank u!
Best Regards
IMCaptor

����: ��: [digester help] How two construct a Object without a
defaultConstructor?
Hi robert:
My class code is like this:
package org.apache.commons.dbcp;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;
public class DriverManagerConnectionFactory implements ConnectionFactory
{
public DriverManagerConnectionFactory(String connectUri, Properties
props) {
_connectUri = connectUri;
_props = props;
}
public DriverManagerConnectionFactory(String connectUri, String
uname, String passwd) {
_connectUri = connectUri;
_uname = uname;
_passwd = passwd;
}
public Connection createConnection() {
try {
if(null == _props) {
if((_uname == null) || (_passwd == null)) {
return DriverManager.getConnection(_connectUri);
} else {
return
DriverManager.getConnection(_connectUri,_uname,_passwd);
}
} else {
return DriverManager.getConnection(_connectUri,_props);
}
} catch(SQLException e) {
throw new DbcpException(e);
}
}
protected String _connectUri = null;
protected String _uname = null;
protected String _passwd = null;
protected Properties _props = null;
}
this class have not the default constructor.
My xml file like this
<connection-factory>
<url>jdbc:oracle:thin:@203.212.6.173:1521:OraTom</url>
<properties>
<property>
<key>username</key>
<value>fdasfd</value>
</property>
<property>
<key>password</key>
<value>fdaf</value>
</property>
</properties>
</connection-factory>
how to convert the xml to the object?
Thank u!
Best Regards

hi
it'd probably be easier for me to help if you could give some concrete
example code and xml. that way, i can talk specifically rather in
general
terms.
