CMP Entity Bean Craziness
Okay, here is the situation. Database: Oracle on Solaris Orion server: 1.5.2 on Windows 2000 Operating System: Windows 2000 I have a database table named FOO. I want to create different entity beans to provide different views of the table named FOO. FOO is a table with many columns. (Sure, I could create one entity bean, and then create "wrapper" classes that provides the views of table FOO that I want, but I didn't want to do that). Many of those column names contain underscores. When I created the first CMP entity bean, I mapped all column names and used the table name as the entity bean name. I wrote the appropriate ejb-jar.xml and orion-ejb-jar.xml and packaged them. In the orion-ejb-jar.xml file, I used the "persistence-name" to map the Java attribute to the proper table column. For all attributes that mapped to a column name with an underscore, I removed the underscore and uppercased the next character. (A column named long_col_name would map to the attribute longColName). So I deployed the entity bean and there were deployment errors. Orion complained about illegal column names. Much later after going around in circles, I looked at the ejb-jar.xml file that Orion generated and I noticed that the values for the persistence-name mapped exactly to the column names of the database table. It *IGNORED* what I had placed there. I had to edit the deployed xml file to get the mapping correct and properly deployed. Now, that's not very nice. Next, I created another CMP entity bean to give a different view of table FOO. I used the entity name FooTimeView and used the table attribute of entity-deployment in the orion-ejb-jar.xml to map the entity to the FOO table. I deployed it and, again, I got errors. I had to edit the deployed xml file to get the correct mappings. I deployed again and it still failed. Only this time, it tried to create a table named FOOTIMEVIEW. (Actually, it *DID* create the table). That's not what I expected to happen. So, I looked at the deployed xml file again and I noticed that the table name had been changed from what I specified. This time, I also looked at the query that was generated and noticed that the column names with underscores had the underscores removed. Now, that's not very nice. I edited that and restarted the server. Now all is well. Okay, now I *KNOW* what I described should not happen. I want to know why it did happen. Has this happened to anyone else, or am I "special"?

HTTP/HTTPS config failure - Ideas?
Greetings. The attached web-site.xml file describes a site where the default web application is the same as a described application. Does anyone have any idea why the default context works, but the HRneXus one does not? The reason for the extra commented out lines was I was doing some testing trying to figure out what worked, and what was not.

Re: MDB with SwiftMQ
It looks like you've typo'ed the name of the resource provider in your orion-application.xml. Are you sure you didn't list it as com.evermind.server.deloyment.ContextScanningResourceProvider there?

Asynchronous MDB
I've been reading of entries about asynchronous MDB not working. When will this be fixed? I have a mission critical app that depends on asynch msg'ing. I successfully convinced my firm to port from Weblogic to Orion :) - Brian Chan
load balancing load
Hi-- I've got a one island, two node cluster. The whole setup works, each of the two nodes fields requests etc. However, the Linux load average on the load balancer fluctuates radically and often goes above 15 or 20! The load averages on the cluster nodes are well below 0.5. Anybody know what might be causing this behavior and how I can fix it? Thanks, Peter T. Brown
MDB with SwiftMQ
Has anyone got a MDB working with SwiftMQ? I've followed the documentation but am getting the following error on deployment... Auto-unpacking \home\modules\jms_tests\dist\jms-tests.ear... done. Error instantiating application 'jms-tests' at file://e:/home/modules/jms_tests/dist/jms-tests.ear: resource-provider cl ass 'com.evermind.server.deloyment.ContextScanningResourceProvider' not found I noticed that 'deployment' is spelt 'deloyment' in the error message, is this a bug or just a typo? I extracted ContextScanningResourceProvider from orion.jar rather than compiling it myself. I'm not sure where to package this class, should it be in the ejb-jar? or in the general app jar? If anyone has this working can you please post your bean deployment config files. My setup is as follows - Cygwin on Win NT 4.0 - Orion 1.5.2 - SwiftMQ 2.1.3 - JDK 1.3.1 Thanks Dave -- David Shepherd [EMAIL PROTECTED] __ Your favorite stores, helpful shopping tools and great gift ideas.

Re: Mysql table create errors with ejbsamples
you need to use another schema definition: this example is for sqlserver i saw that there is no predefined schema for mysql so you need to make one yourself... should be easy if you look at the other definitions hope this helps morten wilken - Original Message - From: "John Hogan" <[EMAIL PROTECTED]> To: "Orion-Interest" <[EMAIL PROTECTED]> Sent: Wednesday, December 19, 2001 3:12 PM Subject: Mysql table create errors with ejbsamples > All, > I've gone through the process of configuring Orion and the ejbsamples to run with a mysql database. Things seem to be nearly correct. Orion connects to the database ok, but dies trying to create tables. The problem seems to be related to syntax or type mismatches between hypersonic db and mysql. Some of the postings on this list seem to suggest that these mismatches can be addressed by defining type mappings in mysql.xml.

How to bind RMI object in the orion server ?
Hello,
Apart from binding ejb instances in the orion server, I would like to
bind RMI objects. I try this piece of code but it failed because the
server can't find the
remote interface (simpleInterface) of the simpleImpl server :
try {
simpleImpl obj = new simpleImpl();
InitialContext ctx = null;
//
// context creation
//
Hashtable henv = new Hashtable();
henv.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClientInitialContextFactory");
henv.put(Context.PROVIDER_URL,"ormi:///simple");
henv.put(Context.SECURITY_AUTHENTICATION,"simple");
henv.put(Context.SECURITY_PRINCIPAL,);
henv.put(Context.SECURITY_CREDENTIALS,);
try{
ctx = new InitialContext(henv);
} catch(Exception e){
System.err.println("Failure when trying to initialize CTX");
e.printStackTrace();
}
ctx.bind("simpleServer", obj);
} catch (NamingException ne) {
System.err.println("Failure when trying to bind the simple server");
ne.printStackTrace();
} catch (Exception e) {
System.out.println("simpleImpl err: " + e.getMessage());
e.printStackTrace();
}
---
The following error is throwned :
Error binding to server: com.evermind.server.rmi.OrionRemoteException:
Disconnected: Class Not Found: simpleInterface
I'm aware that when you deploy an ejb you specify in a descriptor the
remote interface of the ejb but here we do not want
to do this, we only want to bind dynamically others kind of objects in
the naming service.
Has anyone encoutered the same trouble ?

Favourite logging facility survey...
Hi orion gurus, I'm taking a look on logging facilities provided by log4j project and the upcoming Sun jdk1.4. I've, of course, to integrate one of these facilities in my application deployed with orion. What logging facilities do you use, if any of course, and which one dao you think is better between log4j and jdk1.4? I've got my own thoughts about that question but I want to know more experienced developer's ideas.
