RE: EntityBean Events inside tx.

2001-04-09 Thread ramiro


Firstly, I wanted to thank the list for all the responses I had.
But, the problem is that the suggested solutions involve using
'Transacted JMS' services.   I have not been able to make
JMS aware of the transacions it is running on.  Messages
always get sent, inspite of eventual rollbacks.
I only wanted to know if anyone got this working under Orion 1.4.7
Thanks in advance

Here's a description of an implementation of the Observer pattern
for EJB.

http://www.theserverside.com/resources/ObserverPattern.jsp

An alternative is to implement your 'Change Events' as JMS messages, if
you are using 'Transacted JMS' messages are only 'published' when the
encompassing Tx is committed.

 We would like our entity beans to propagate events in the same
 fashion than regular java beans.
 Therefore we must, for example, send events notifying of property
 changes inside the bean.  The problem with this is that we don't know
 if this method was called inside a transaction that might be
 rolled back later on, and hence the property change event
 should not have been sent at all.
 Clearly, we want to propagate the events only when the transactions
 are commited.
 Is there a standard "pattern" to manage this sort of thing ?

XA Queues work ?

2001-04-05 Thread ramiro

Hello list,
We've been trying to use, transaction aware queues with no success..
The problem is that messages always get sent, inspite of rollbacks.
We don't know if it is our fault or this type of queues don't work properly
in Orion.

Here is a snip of our configuration and what we are doing.

---
jms.xml:
 xa-topic-connection-factory location
="jms/observerConnectionFactory"/
 topic name="Observer" location="jms/observer"
 /topic
---
/** Some session bean's method */

UserTransaction transaction = ctx.getUserTransaction();
transaction.begin();
sendMessage();
transaction.rollback();

---

/**
   Inside the sendMessage method.
   We have tryied to use Topic and Queue types.
*/


Topictopic = null;
 XATopicSession  session = null;
 XATopicConnection   connection = null;
 XATopicConnectionFactory connectionFactory = null;
 TopicPublisher   publisher;

 InitialContext  initialContext = new InitialContext ();

connectionFactory = (XATopicConnectionFactory) initialContext.lookup
("java:comp/env/jms/observerConnectionFactory");
topic = (Topic) initialContext.lookup ("java:comp/env/jms/observer");

initialContext.close ();

connection = connectionFactory.createXATopicConnection ();
connection.start ();
session = connection.createXATopicSession ();
publisher = session.getTopicSession ().createPublisher (topic);

Message message = session.createMessage ();

message.setStringProperty ("str", event.getSource ().toString ());
publisher.publish (message);
session.close ();
connection.close ();

autoupdate

Hi,
  Everytime I run autoupdate, it updates many packages to version 1.4.7 
(which was already installed).
  That did not happen before, autoupdate used to realize when my system was
already up to date.
  Thank you.

RE: Shutting down orion

2000-11-08 Thread Ramiro Diaz Trepat

Guys, there is an AWEFUL bug in jdk1.3 when using
URLConnection.getInputStream();
This method worked fine until version 1.2.2 of the jdk.
The failure of the shutdown process is probably related to
this bug.
Here is the BugParade url in sun where you can see all the
detailed descriptions.
http://developer.java.sun.com/developer/bugParade/bugs/4333920.html
I wonder why did they have to touch this pice of code
which used to work like a charm since version 1...
It only has 25 votes by now, CAST YOUR VOTES !

 Anyone else noticed this?

Yes, I noticed this too. But only with the new Sun jdk1.3 . In IBM jdk1.3,
it
works fine.

importing keypairs

2000-11-07 Thread Ramiro Diaz Trepat

Hi all,
why keytool can't import keypairs genereted for example
by openssl.
Is there a workaround for this matter ?
We have some keypairs with their thawte certs and we will
not be able to use them with orion since we can import
the certificates but we can't import the key-pairs...
TIA
