RE: Questions about Orion
Klaus, A hundred times faster? BullFeathers! That is not possible since one of Borland AppServer's best features is HotSwap technology for supporting nonstop deployment and nonstop updating and maintenance of EJBs.

SQL Server 2000 database -- That's a tough one. I don't know any IT managers recommending this beast. But if you got to live with it ... make sure you test the jdbc drivers with all necessary uses of sql including things like LIMIT, CLOB, BLOB as well as 100's of open connections. These are the key database needs for a appserver servicing the web. 2. Orion uses the Java 1.3 jvm from Sun, IBM or others. As they say, if it runs on one, it runs on all. 3. We use IBM's jvm with absolutely no problems. 4. Scalability is determined by your clustering needs. Orion clusters httpsessions in islands of two to four servers. Statefull Session Beans are not clustered, but entity beans and slsb's are easily set up in a clustered environment. Orion is easily the fastest jsp/servlet engine on the planet, and along with some very good performance numbers on the ejb side, you can out do other app servers by a factor of 3 to 1. By the way, Orion by itself can out do IIS by six to one! Oracle thought so much of the Orion performance, they licensed the software as the core of their j2ee application server. 5. j2ee security is used on Orion, you can implement your own user security, or link up with ldap, or use the builtin usermanagers for databases. SSL is also a feature of Orion, but I would recommend locking down your web server with SSL, or use a hardward accelerator, and proxying Orion outside the dmz. This is how most firms implement appservers. 6. Like anything, if you run it on Windows, it will be compromised. We have not had any security troubles with Linux RedHat 7.1 and orion. 7. Ironflare doesn't really provide the technical support that some need. With Ironflare's encouragement, companies like Flowsheet Technologies and others provide subscription based customer support for Orion. Join our site, www.elephantwalker.com, its free, and sign up for a subscription when you need some help. We also provide a course for Orion in the San Francisco Bay Area. regards, the elephantwalker www.elephantwalker.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Vlad Vinogradsky Sent: Thursday, September 20, 2001 8:22 PM To: Orion-Interest Subject: Questions about Orion I am evaluating the Orion server for use in a production web site which would be hosted by a hosting services provider. It would run on a Windows 2000 box alongside other web sites serviced by IIS and will manage data in SQL Server 2000 database. I have a few questions I wasn't able to find answers to and I wonder if you can help me with them. 1. I wonder if anybody had any negative experience using Orion server on Windows 2000 or with SQL Server 2000? I-Net jdbc products are going to be used. 2. Any comments on performance, scalability and availability of the Orion server on Windows 2000? 3. What VM is best to use to run Orion server? 4. Does it have auto start and restart features? Do you have to have an interactive logon session to start it? 5. What security context does it run in? 6. What is Orion server security track record? Has it ever been compromised or taken out by DOS attacks? 7. Any comments on IronFlare's technical support? It looks like there is no live tech support - just email. All input is welcome. Thanks, Vlad
application-client.xml ?
Hi, I'm an EJB newbie. I wrote a stateless session bean and deployed it with orion server. Accessing it from servlets/JSPs that are included in the .ear file by configuring the xmls works fine. But I do have a problem figuring it out for standalone clients. What are the exact steps that should be taken in looking up, creating and accessing a bean from a standalone client that resides on another machine given the following deployment descriptors: ejb-jar.xml and orion-ejb-jar.xml ? Thanks ** ejb-jar.xml: ?xml version=1.0? !DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd' ejb-jar enterprise-beans session descriptionAdds, subtracts, multiplies and divides/description display-nameSession Bean Calculator/display-name ejb-nameCalculatorService/ejb-name homecom.beans.CalcHome/home remotecom.beans.Calc/remote ejb-classcom.beans.CalcBean/ejb-class session-typeStateless/session-type transaction-typeBean/transaction-type /session /enterprise-beans /ejb-jar ** orion-ejb-jar: ?xml version=1.0? !DOCTYPE orion-ejb-jar PUBLIC -//Evermind//DTD Enterprise JavaBeans 1.1 runtime//EN http://www.orionserver.com/dtds/orion-ejb-jar.dtd;; orion-ejb-jar enterprise-beans session-deployment ejb-ref-mapping location=ejb/Calc name=CalculatorService/ /session-deployment /enterprise-beans /orion-ejb-jar _ Do You Yahoo!?

Subject: Classpath Structure Error?
SYMPTOMS When I invoke my webapp, the first request to the server causes the front servlet to throw a class-def-not-found exception for the app's session class, which it loads dynamically. The class in question is in fact present in the app's war file, in the web-inf classes directory. To nail the problem down, I printed the jvm's class path, immediately before the attempt to load the session class. With newline chars inserted after each ';' for legibility, the classpath looks like this: classpath: orion.jar; C:\j2ee\home\ejb.jar; C:\j2ee\home\activation.jar; C:\j2ee\home\jdbc.jar; C:\j2ee\home\jndi.jar; C:\j2ee\home\jta.jar; C:\j2ee\home\mail.jar; C:\j2ee\home\xerces.jar; C:\j2ee\home\tools.jar; C:\j2ee\home\lib; C:\j2ee\home\lib\aplWeb.jar; C:\j2ee\home\lib\classes12.jar; C:\j2ee\home\lib\p6spy.jar; C:\j2ee\home\applications\podAdmin-eap\podAdmin-ejb.jar; ; C:\j2ee\home\applications\podAdmin-eap\podAdmin-web\WEB-INF\classes The not-found class resides in the WEB-INF/classes directory, which for a reason not known to me, has a null element immediately before it on the classpath. Everything else on the classpath looks reasonable to me. QUESTIONS Would this null element hide my app classes from the system class loader ? If the null element is to blame how might it have gotten into the class path ? BACKGROUND (The only thing I did was ...) -- This app used to work, before I refactored my ejb classes into an abstract superclass and app-specific subclasses. The super class implements connection to a single datasource, and a few generic business methods such as getDbDate(), getDbName(), etc. Concrete subclasses implement the app-specific business methods. Everything runs smoothly during build and deploy of the ear file, then at run time the class-loading problem shows up. SPECULATION --- Given that orion builds the runtime classpath for an application, and that it generates stubs and skeletons from ejb remote interface class files, is my refactored config of classes the problem ? The null entry on the path comes right after the entry inserted by Orion for my ejb jar. Does orion (or the spec) constrain how an ejb Remote and Bean are configured ? Can they be split into super and sub-classes ? Should I report this as a bug ?

RE: Newbie question
Orion is simply an J2EE server (http, jsp and servlets, ejbs, jndi, jms), plus a relatively immature gui console. It is not a development environment. Many folks use ANT from apache.org as a make-like facility for coordinating compiles, and builds of ear files from compiled classes. Hot deployment by dropping an ear into orion/applications/ works well. Hope this helps. I user Jbuilder for GUI construction, and idea-intellij for most other coding. Hope this helps. -Original Message- From: Pito Salas [mailto:[EMAIL PROTECTED]] Sent: Friday, September 21, 2001 3:41 PM To: Orion-Interest Subject: Newbie question I've been working with the Sun J2EE RI.
