Newbie - using EJB and databases
Hello all, I am still new to the whole EJB thing, but I have a grasp on it. However, the one thing I am foggy on is how to use a database. I know that I set up the db connection in the data-sources.xml file, but what is the syntax to use that in an application? Where could I find an example of that?
getting a cached copy of jsp on reload
Using Orion 1.5.2 When I redeploy an application and access a jsp page the first time I can debug through jsp pages, and ejb's. However when the first pass through the code is finished, if I press reload on the browser it does not go through my code. It apears to get a chched copy of the page, which displays instantly. I am using Netscape browser, and Linux for a OS. I have no caching proxies, this is all happening on one machine. If I make a minor modification to any file in the app (ear file) and redeploy it, I get to debug again. If this is the way it's suppose to work then it's a bug. My jsp page could very well be accessing constantly changing data in a database and serving a cached copy is not the right thing to do, even one second from the last access. Is there a config parm I've missed? Wendell Nichols

Null values in Jsp page
Hi, There is something strange with Orion 1.5.2 : when I print a variable which contains a null value in a Jsp page, Orion prints "null" instead of an empty string. This doesn't appends with the previous version of Orion I had (1.4.5). Does anybody know how to solve this problem ? Regards, Marc SCHNEIDER

Re: Support for MySQL
Yup . . . it sure is. I use it as well as oracle and db2 for cross compliance testing. As far as it being a 'success story', i personally wouldn't use it as a production RDBMS.

JMSChat example
When trying to run the jmschat example I receive a stack error while trying to get the conncectionfactory. From reading the documentation it appears that I need something in the jndi.properties file on this line java.naming.provider.url=ormi://10.1.37.124/ If I add something like jmschat or application orion reports no such domain. What goes here or what configuration parameter is not set. Does the example run unchanged anywhere.

Re: Support for MySQL
The latest releases (as of 3.23.34a) of MySQL support transactions by using Berkley DB. I'm using MySQL at the moment. The main anoyance I've got is that it doesn't have sub-selects, apart from that, works great. I haven't tried using transactions though as my data is read only. Ray Harrison wrote: Mysql doesn't support transactions (or the last time I checked it didn't) - so it can be limited - but yes, orion interacts with the database just fine. I would suggest another database to try would be SAP DB (www.sapdb.org) which is an open source database delivered by SAP AG - I love it. There is a sap database schema in the orion download. --- Nicolai P Guba [EMAIL PROTECTED] wrote: Hmmm, I've found that PostgreSQL is supported. Has anybody got any success stories with mySQL?

RE: IBM JDK with Orion?
Eddie, We do not start orion under su. We use an account set up for orion. The .bash_profile in the account exports the LD_ASSUME_KERNEL. We also use a startup script to crank up orion. You are right, that every user which starts up orion would either have to put this in their bash_profile, or do this manually. We used the startup script available at www.orionsupport.com, see the article on running orion under unix/linux. We had problems with bad memory, but that didn't have anything to do with the ibm or orion.

Re: Aaarrrghhh!! CSS and Servlet again
You are misunderstanding when the CSS gets used. CSS is client-side. When the browser parses the html you send, it will see the LINK tag and download the external css documentto apply styles. A simple way to deal with this is have your CSS off the document root or in a sub-dir just off the doc-root: LINK REL="stylesheet" TYPE="text/css" HREF="/css/mycss.css" so, the file could be dowloaded if someone typed in this URL: http://www.abc.com/css/mycss.css HTH - Original Message - From: Brynolf Andersson To: Orion-Interest Sent: Wednesday, June 20, 2001 3:28 PM Subject: Aaarrrghhh!!
