The problem appears to be in digester performing a SAX parse, rather than in
messenger per-se. So it seems like you've an old SAX jar on the classpath
somewhere?
It might be worth trying the xml-apis-1.0b2.jar instead as thats actually
more recent (the 2.0.* versions are wrong).

Posted by Greg Dunn <gr...@nisc.cc>.
robert:
Thanks for the assistance. As it happens storing the value as a Timestamp
suits my purposes and it works with "off the shelf" BeanUtils. However I'm
sure your solution will come in handy with other nonstandard data I need to
deal with.

hi greg
the standard SqlDateConvertor in beanutils uses java.sql.Date.valueOf to
perform the conversion. this method requires a date in sql date format ie
yyyy-mm-dd. i don't think that the conversion will work given an input in
your format.
there is an easy way to make this work in beanutils. you can create a
custom converter and then register it to handle your java.sql.date's.
i'd create a custom convertor by extending SqlDateConverter and overriding
convert with something like
<untested-code-warning>
public Object convert(Class type, Object value) {
if (value == null) {
return super.convert(type, value);
}
return super.convert(type, value.toString().substring(0, 10));
}
</untested-code-warning>
see java docs for explanation of how to register a custom converter.

BeanUtils and Dates
Posted by Greg Dunn <gr...@nisc.cc>.
I'm using BeanUtils to populate a bean with records from a resultSet via a
HashMap built using the metadata.getColumnName for property names and the
rst.getString for values in the usual way. A date field in the resultSet
(we'll call it "myDate") is causing an exception.
Debug log shows ConvertUtils is attempting to "Convert string '2002-09-25
01:05:43.0' to class 'java.sql.Date'" but it cannot and throws a
ConversionException.
My bean imports java.sql.Date, and the instance variable is:
private Date myDate = null;
My setter is:
public void setMyDate(Date myDate) {
this.myDate = myDate;
}
How do I get the date into my bean as a date? Am I stuck with setting it as
a String?

Re: [messenger] problem running messenger
Posted by James Strachan <ja...@yahoo.co.uk>.
Thanks for this Jukkis. Sorry it took so long to get to, but I've finally
committed your WebLogic deployment descriptor.
Incidentally rather than write 2 new programs to send & receive, you can
reuse the existing utillity programs to send & receive messages using your
config file.
e.g. instead of SendTest and Receive test you could do
java -Dorg.apache.commons.messenger=file:c:/dev/messengertest/messenger.xml
\
org.apache.commons.messenger.tool.Producer \
weblogic.examples.jms.exampleQueue message.txt
Where 'weblogic.examples.jms.exampleQueue' = the queue to use and
'message.txt' is a file name containing the message to be sent.
The above will send the message on the queue using your deployment
descriptor. Then to consume the message try..
java -Dorg.apache.commons.messenger=file:c:/dev/messengertest/messenger.xml
\
org.apache.commons.messenger.tool.Consumer \
weblogic.examples.jms.exampleQueue

VS: [messenger] problem running messenger
Posted by Jukka Nikki <Ju...@Kolumbus.fi>.
Thanks James,
I did find the problem. Tomcat 3.2.1 embedded inside JBuilder 5 did the
trick. After this it was quite straightforward, some quirks still..
1) Sample messenger.xml did contain reference to dtd file that I didn't have
(I took reference off)
2) Properties needed some thought before I got them fine (studied
javax.naming.Context static values)
3) Examples just needed addition of exception handling
To help any of you I'll put what I did to this message. This works with
WLS7+SP1 example server. Just install it, change configuration file path
from source and run these from your command line..
Messenger.XML
-------------
<?xml version="1.0" encoding="UTF-8"?>
<manager>
<!-- WLS 7 + SP1 queue test -->
<messenger name="WLS_queue" jndiDestinations="true">
<jndi lookupName="weblogic.examples.jms.QueueConnectionFactory"
topic="false">

<value>weblogic.jndi.WLInitialContextFactory</value>
</property>

<name>java.naming.provider.url</name>
<value>t3://127.0.0.1:7001</value>
</property>
</jndi>
</messenger>
</manager>
SendMessage.java
----------------
package messengertest;
import org.apache.commons.messenger.*;
import javax.jms.*;
import javax.naming.*;
import org.apache.commons.logging.*;
public class sendMessage {
public static void main(String[] args) {
// sending
//Log log = logFactory
Log log = LogFactory.getLog("Tester");
try {
// --- NOTE: Change path!!!
MessengerManager.configure("file:c:/dev/messengertest/messenger.xml");
log.info("Messenger configured");
// get a Messenger and Destination
Messenger messenger = MessengerManager.get("WLS_queue");
log.info("WLS_queue initialized");
Destination destination = messenger.getDestination
("weblogic.examples.jms.exampleQueue");
log.info("Destination found");
// now lets send a message
TextMessage message = messenger.createTextMessage("testi");
log.info("Message created");
messenger.send( destination, message );
log.info("Message sent");
} catch (JMSException e) {
e.printStackTrace();
log.error("Sending error", e);
}
}
}
ReadMessage.java
----------------
package messengertest;
import org.apache.commons.messenger.*;
import javax.jms.*;
import org.apache.commons.logging.*;
public class ReadMessage {
public static void main(String[] args) {
// sending
//Log log = logFactory
Log log = LogFactory.getLog("Tester");
try {
// --- NOTE: Change path!!!
MessengerManager.configure("file:c:/dev/messengertest/messenger.xml");
log.info("Messenger configured");
// get a Messenger and Destination
Messenger messenger = MessengerManager.get("WLS_queue");
log.info("WLS_queue initialized");
Destination destination = messenger.getDestination
("weblogic.examples.jms.exampleQueue");
log.info("Destination found");
// now lets read a message
Message message = messenger.receive(destination);
log.info("Message received");
System.out.println("Got text: "+((TextMessage)message).getText());
log.info("Message parsed");
} catch (JMSException e) {
e.printStackTrace();
log.error("receiving error", e);
}
}
}
If any of you needs straightforward message receiving and sending facade
this one is easy to understand and gives some extras too..
