fyi: 1.5.4 still stacks rather than queues JMS messages
Re the problem reported a couple weeks back by Jorge Jimenez and confirmed by myself, I tested 1.5.4 to see if they had fixed this problem, but it's still there. Just set max-instances to 1 and load up with a lot of messages, it works just like a stack. Doh. Maybe I'll have time to put this into Bugzilla next week... Is _everyone_ using a third party JMS with Orion? geoff
Re: getClass().getClassLoader().getResource(fileName) problem
if your "file.ini" is in "c:\orion" try the following:
String path = "c:\orion\file.ini";
Properties props = new Properties();
props.load(new FileInputStream(path));

getClass().getClassLoader().getResource(fileName) problem
Hi,
I tried to open a property file from within my
custom UserManager program, however, Orion was unable
to find my file. I just don't know where should I put
my property file so it can be located by the following
command:
props_ = new Properties();
try {
URL aURL =
getClass().getClassLoader().getResource(fileName);
InputStream in = (InputStream)aURL.openStream();
props_.load(in);
Thanks a lot.

Wow. It seems that 1.5.4 is released!!!
See subj.
Problem on Netscape Browser - Document Contained No Data
I have an application that uses a custom user manager and form-based authentication on Orion 1.3.8. Things work great with Internet Explorer, but with Netscape 4.7, the browser pops up a "Document Contained No Data" error when attempting to login - as if its not getting anything back from the server. If I turn security off and request the same URL, I get right in. Anybody have any idea what is causing this? Thanks in advance, Marc
Accessing HypersonicSQL
I have a few questions about accessing HypersonicSQL when acting as the data source for Orion. I am assuming the HSQL is running in the same JVM as Orion (the default configuration.) How do I access the HypersonicSQL data source from Java using JDBC, but outside the JVM of Orion ? Is there a dirver and URL to use ? How do I access the HypersonicSQL data source from Excel running on a desktop ? (i.e. Is there "native" ODBC access to HypersonicSQL when the client is running on a Windows desktop ?) A question on best practice; when updating a J2EE data source in “batch” (perhaps posting information at night) do I write a program that runs in the Orion JVM (how do I invoke it ?) or do I write a program that updates outside of Orion ? In both cases I would use EJBs (right ?)
Re: problem with ResultSet Object
ResultSet is not a seralizable object. ResultSet is opened cursor to the database. If you want to pass ResultSet to client i.e jsp/servlet either conver the ResultSet data into you own custom objects or collection classes. The other alternate is to use CachedRowSet. CachedRowset is serializable object and contains all the information what ResultSet contains. You can get more information on RowSet at http://www.javaworld.com/javaworld/jw-02-2001/jw-0202-cachedrow.html -kesav - Original Message - From: sachin mahajan To: Orion-Interest Cc: sachin mahajan Sent: Wednesday, February 13, 2002 8:50 PM Subject: problem with ResultSet Object Dear Sir Currently i am working om the orion server. i have deployed my application properly.

Re: problem with ResultSet Object
Sachin: I think you have a design problem. Please, anyone correct me if you think i'm wrong. From inside a JSP page you should not access a recordset returned by an EJB. EJB components represent mostly bussines objects that contains rules and data access services. From outside the EJB (from a JSP page or remote client) the data that this component encapsulates should be accesed using services that returns serializable data types (objects thart starts with an uppercase or even another EJBS throught it's remote interface). In design terms, you are innecesarily coupling presentation layer with data layer if you return a ResultSet. Capture the resultset in private variables of your EJB and provide "getter" services if it is a stateful bean, or you can return a Hashtable with attributes if it is a stateless one. Hope this can help you.
