Jabber and Orion
Has anyone tried Jabber with Orion? what is your experience? Hadi Jabber is an instant messaging server similar to ICQ..., completely built on XML www.jabber.org

hi, is it possible to use the JMS Server with non -java applications as JMS Clients? (both pub/sub p2p) Hadi
Orion tries to use more connections that the maximum # of connections that are allowed! Why?
If I use Orion's connection pool with a database that has only a few connections (5-10) and I explicitly define it in the data-sources.xml file Why do I get error messages saying that the maximum number of applications is already connected to the database. " 2001-04-05 15:16:30,012 ERROR [ApplicationServerThread] (Controller.java:87) - com.evermind.server.rmi.OrionRemoteException: javax.ejb.EJBException: Error saving state: [IBM][CLI Driver] SQL1040N The maximum number of applications is already connected to the database. SQLSTATE=57030; nested exception is:javax.ejb.EJBException: Error saving state: [IBM][CLI Driver] SQL1040N The maximum number of applications is already connected to the database. SQLSTATE=57030 " as I understand the connection pool, Orion should not use connections if the maximum allowed is already in use? could someone explain me Orion's Connection pool with a limited database(limited number of conections) Thanks Hadi

Hello all, I've been trying for weeks now getting any response from the orion team to no avail. First of all, I wanted to post a serious problem in Bugzilla but for that I need a account password. I've tried and tried, but never ever received a password after creating a new account or after requesting the account password to be send again. Then I tried sending a message directly to orion support. No response. Then I posted my problem to this list http://www.mail-archive.com/orion-interest@orionserver.com/msg 09692.html (Serious problem with Orion transaction processing: multiple connections used within a single transaction) februari 13, 2001, including a test case. I mailed this problem again to [EMAIL PROTECTED] februari 19, 2001. No response. I mailed Magnus Stenman directly on februari 27 explaining these problems and requesting access to Bugzilla. No response. I'm not clear what options are left, but we are seriously considering other application servers right now as this kind of support is really not acceptable in the long run. At least a simple acknowledgment of the reception of the problem would give us the idea that someone is actually monitoring [EMAIL PROTECTED] mailbox. It doesn't seems to be the case right now. Having to switch to another application server is something I really don't like. Overall I like the orion application server very much (certainly for development). We consider the bug we encountered as very, very serious which will have to be solved otherwise we just don't have another option. The bad (non-existing?) support makes this truly serious. If anyone did have some contact with the orion team (mailbased or otherwise) in the last month's I would be very grateful to know how they did that. The same question I have for anyone how was able to create a Bugzilla account recently. Lastly, somewhat less important: does anyone receive the orion-interest maillist still directly to their mailbox? Since Januari 11, 2001, we didn't receive any mail anymore, and can therefore only access the maillist at http://www.mail-archive.com/orion-interest@orionserver.com.

RE: Help: deadlock with concurent access to entity bean
Storing Images works for me using DB2
it should also works with DBs supporting BLOB
1) first check that your db schema config file defines a mapping between
java.io.Serializable and BLOB
2) implement a Picture class that implements
Serializable
---
public class Picture implements Serializable {
public Object data;
public Picture(){}
public void setData(byte[] data) {
this.data = data.clone();
}
public byte[] getData() {
return (byte[])data;
}
}
3) in your bean declare your picture as an instance of Picture class and
deploy it as a container
managed field
Hope it'll work for you
As you read it in my previous message, I'm facing deadlocks with a heavy
concurent access to PictureBean
I'm still searching for a solution
