Re: Can't call an EJB from Within another EJB
Remember that your EJB-REF tage are scoped within each bean, so that the same tag name can refer to different things, depending upon which bean it is defined in. So, my guess is that you didn't include an EJB-REF tag *in the bean definition* for the bean you want to reference. If thats not the problem, post your deployment descriptor for us to look at.

MightyWords has a report that doesn't paint Orion very well. And is wrong in part.
Hiya, Just got a report from MightyWords. "The Concise Guide to Enterprise Java Bean Servers" by Subodh Atal, Ph.D. 71 pages. Quite interesting reading, and Orion rates as one of the 22 servers rated. Unfortunately Orion doesn't get the attention it deserves. And the doc is partly wrong is a few areas, particularly in the clustering arena in Orions case. I suggest that Orion staff get in touch with the suppliers (http://www.app-serv.com) and request a copy, review it and respond. (And to this group is poss ;-) It's a document that could have an impact on their sales as many companies may be using it to decide on a server. Sorry I can't include the doc.

Servlet Caching Bug?
We've experienced what we believe to be a bug with Orion in terms of Servlet Caching. The situation is detailed here: 1. We've setup a servlet as a filter for xml, by editing orion's global-web-application.xml thusly: servlet-chaining servlet-name="XSLPainterServlet" mime-type="text/xml"/ servlet servlet-nameXSLPainterServlet/servlet-name servlet-classcom.apama.xsl.XSLPainterServlet/servlet-class /servlet 2. Additionaly, we've edited orion's application.xml thusly: library path="../../dev/ApplyXSLServlet"/ and a jar file is placed in this directory containing the XSLPainterServlet file. We've tested this with an XML file and it works fine. The problem is when we recompile the class file and rebuild the JAR file while Orion is running, the new servlet is not used. Orion continues to use the old servlet in memory. Is there anyway to hot-redeploy servlets without explicitly restarting orion? Thanks, Ted Rice
RE: ORION running under Solaris Environment
One thing we have found is the Solaris JDK 1.3 is very, very slow running Orion (less than half the speed of a MHz equivalent PC running Windows). You'll want to use the last production JDK 1.2.2 (it's either _06 or _05a). It performs much better. Now the question is why is the Solaris 1.3 the only one that is slower than the platform's JDK 1.2? On Linux and NT 1.3 is considerably faster.

can client see dependent objects (ejb2) ?
I save successfully saved an ejb w/ dependent object into the database. But when I try to pull the ejb back (w/dependent object), the client throws an exception saying it cannot find the dependent object class. Client code snippet: system.out.println(contact.getName()); // this works Address a = contact.getAddress(); // this throws exception The ejb attributes print out on the screen fine, but when I try to get the Address dependent object the *client* throws this exception: java.lang.ClassNotFoundException: Address_Dependent0 Now, I think the problem is obvious. My class is called "Address" and Orion compiled the class on the server and called it "Address_Dependent0". Obviously, the client isn't going to see that. My question: Can the client not see dependent objects at all? Should I write another Address class and copy all the dependent Address class attributes into it? Is this addressed in the spec (I didn't see it)? I hope this is how it is supposed to work, I sure hope they change it - it seems a huge waste of time to have to write 2 classes for each dependent object. -tim

RE: Clustering Advice, Software or Hardware
Hi there, First, you definitely want to use the application specific clustering, with a load-balancer feeding to two or more, per island. If your not familiar with Orion clustering, your in for a nice surprise..its VERY easy to do. Orion even comes with its own software load-balancer that is "Orion aware" and as you add more Orion app servers, they automagically appear on the server that the Orion load-balancer is running on. You even see all incoming requests, what server they went to, when a computer is added or taken away, etc. There is a nice doc on the orion site, I forget the URL, that explains a good deal on how to easily set up clustering. I have tried it and it works. The thing to know, however is that HttpSession data (the stuff that the "state" of a client is stored in via a session), needs to be failed over, so that if one server goes down, they are still connected via the session data. If the HttpSession objects were not failed over, when a server went down, everything in the clients "cart" (if say you were building a cart system), would be gone. On our site, people have to log in. We store an object in the HttpSession session for each client that indicates if they are logged in or not. If the server they were on went down, they would no longer be logged in, even if a load-balancer was in place and fed them to another server. The idea behind Session fail-over is that you set up an island of web servers..and in that island all HttpSession data is copied to each of the servers. Therefore, if I am a new client and hit your ip (a load-balancer for example), my request is sent to any one of x number of servers in a specific island (a cluster). My HttpSession is created and its "replicated" to all the servers in the island. Therefore, if you have 3 machines, each machine gets not only its data, but the data of the other two servers..so memory requirements go up a bit on each machine. With Orion, because of the way it clusters, I would put 3 servers per island, with two islands, for "minimum optimum fail-over". You don't have to put fast machines..a single $1200 PIII or AMD Athlon based pc with 500MHz cpus are fine. I ran a simple "login" load-test with 25 users on my PIII650 workstation with Orion, with the Interbase database server running on it as well, and I was able to achieve 4milliion pages per day. Ofcourse..it helps that it is on my local box, but even if the database was on a different machine, I would achieve similar results. And this with only 2 database connections in the pool! Imagine the performance you can get from a 3-server cluster of 500Mhz PCs with 1GB of memory each. Anyways, you can cluster with 2 servers per island, but I recommend 3 simply because if one goes down, you still have a cluster. I wouldn't go with 4..instead I would set up two islands, each with 2 computers if you can only use 4 servers. You can easily add a machine to the island too. The reason being..the more servers you have in an island, the more memory each will need to handle the HttpSession objects of the other servers in the island. Therefore, I think 3 is perfect, each with 1GB (or more) of memory. These days, you can buy nice Dell servers for about $4K each with 900Mhz cpus, 1GB memory, Ultra SCSI 160 hds, etc. Hope that helps.

My problem is that EJB A uses EJB B, but my servlet, when it tries to get EJB A, throws the naming exception. The code in EJB A hasn't even ran yet..and the stack trace says it can't find EJB B! That is strange to me on why if the code in EJB A that uses B isn't even running yet..just when the object is trying to be found, that it says it can't find EJB B. Must be some mechanism of EJB containers that makes sure they all exist. My EJB A does a JNDI call to java:comp/env/ejb/Test and that should work according to the ejb book I have. That is how a session bean uses an entity bean supposedly. From what I read, a session bean (or I suppose any ejb) must use a JNDI lookup for every bean it wants to use. God forbid if I had a bean that needed to use 50 other beans! Isn't there a way to simplify this process? Also, it appears EJB 1.1 entity CMP stuff is very limited..VERY limited. I can't have any type of joins. How then is a join done? Does EJB A (session) that uses two entities, with entity A having a join to entity B..does this have to be done in code? You have to get all the entities of both A and B, then in code do a loop through all As and on each iteration do a loop through all B's and if the fields of both that are in the "query" match, store that in a vector, then return that result? That seems like a whole lot of code just to do a simple one to many join of two tables. It's enough to make me use standard JDBC sql, instead of entity CMP. -Original Message- From: J Davis [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 25, 2000 10:21 AM To: Orion-Interest Subject: Can't call an EJB from Within another EJB We have gotten our Orion server(1.3.8) to work with EJBs on a singular level(i.e. we can call EJB A, B or C and it works fine.) But If one of our EJB's tries to call another(i.e. A calls B) A throws a naming exception that it can't find the EJB reference when doing a jndi lookup. Is there a dependency tag or something within one of the XML files that denotes EJB dependencies on one another? I'm sure this is something simple, but it is getting annoying.
RE: can client see dependent objects (ejb2) ?
I believe you must use a Dependent Value class to get dependent objects .. the idea with dependents is that they are tightly associated with an entity, and the entity should use them and expose in it's own interface .. see the ejb spec 9.3.1 on granularity, and dependent objects and value objects in 9.7.x jd -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Tim Drury Sent: Thursday, October 26, 2000 1:05 PM To: Orion-Interest Subject: can client see dependent objects (ejb2) ? I save successfully saved an ejb w/ dependent object into the database. But when I try to pull the ejb back (w/dependent object), the client throws an exception saying it cannot find the dependent object class. Client code snippet: system.out.println(contact.getName()); // this works Address a = contact.getAddress(); // this throws exception The ejb attributes print out on the screen fine, but when I try to get the Address dependent object the *client* throws this exception: java.lang.ClassNotFoundException: Address_Dependent0 Now, I think the problem is obvious. My class is called "Address" and Orion compiled the class on the server and called it "Address_Dependent0". Obviously, the client isn't going to see that. My question: Can the client not see dependent objects at all? Should I write another Address class and copy all the dependent Address class attributes into it? Is this addressed in the spec (I didn't see it)? I hope this is how it is supposed to work, I sure hope they change it - it seems a huge waste of time to have to write 2 classes for each dependent object. -tim

That's what 2.0 is hopefully going to do a great deal to help. However, you can do custom finder queries in Orion so you can specify the entire finder SQL in the orion-ejb-jar.xml file.

Re: Obtaining an SSL Certificate
Actually, after installing the newer version of the JSSE, I was able to get the test certificate form Verisign to work properly, running 128 bit. Even after setting the shared attribute to true, IE still seems to renew the session every 2 minutes or so, but Netscape seems to do fine. I think IE is trying to be to 'smart', and after so much idle time, it re-negotiates with the server, and new session is created. Any thoughts on how to defeat this? Thanks for the info on JSSE!

We've experienced what we believe to be a bug with Orion in terms of Servlet Caching. The situation is detailed here: 1. We've setup a servlet as a filter for xml, by editing orion's global-web-application.xml thusly: servlet-chaining servlet-name="XSLPainterServlet" mime-type="text/xml"/ servlet servlet-nameXSLPainterServlet/servlet-name servlet-classcom.apama.xsl.XSLPainterServlet/servlet-class /servlet 2. Additionaly, we've edited orion's application.xml thusly: library path="../../dev/ApplyXSLServlet"/ and a jar file is placed in this directory containing the XSLPainterServlet file. We've tested this with an XML file and it works fine. The problem is when we recompile the class file and rebuild the JAR file while Orion is running, the new servlet is not used. Orion continues to use the old servlet in memory. Is there anyway to hot-redeploy servlets without explicitly restarting orion? Thanks, Ted Rice
Transaction not rolled back if exception thrown from ejbCreate method
Heya.. Throwing an system exception from an ejbCreate method with a "Required" transaction-attribute should result in the container rolling back the transaction. However, this doesn't seem to be the case with Orion 1.4.0. Is Orion doing the right thing (not rolling back) or not? My interpretation of the EJB 1.1 spec is that it *should* rollback the transaction automatically. Markus -- Markus Holmberg | Give me Unix or give me a typewriter.

Deploying J2EE RI ConverterApp on Orion
First off, I'm an Orion newbie, so I'm probably doing something stupid. I'm trying to deploy the ConverterApp example distributed with the J2EE RI from Sun (described in Chapter 2 of its User Guide). I added this line to server.xml: application name="Converter" path="/my/path/ConverterApp.ear" / To run the ConverterClient with the J2EE RI, I had to include in the classpath the ConverterAppClient.jar file that was created when I deployed the application. But I didn't think I'd need to do that with Orion since it builds the stubs on demand. I [naively] figured all I had to do was set the JNDI properties on the client command line properly and everything would just magically work! But instead I got the following error. $ java -Djava.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory -classpath $HO\ ME/usr/orion/orion.jar:. ConverterClient Caught an unexpected exception! javax.naming.NamingException: META-INF/application-client.xml resource not found at com.evermind.server.ApplicationClientInitialContextFactory.getInitialContext(JAX, Compiled Code) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java, Compiled Code) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java, Compiled Code) at javax.naming.InitialContext.init(InitialContext.java, Compiled Code) at javax.naming.InitialContext.init(InitialContext.java, Compiled Code) at ConverterClient.main(ConverterClient.java, Compiled Code) Why does Orion require an application-client.xml file? Assuming I figure out what that file should look like, do I really have to wrap it and the client class up in a jar file just to run a simple test??? Thanks for any light you can shed.
Re: Obtaining an SSL Certificate
We are using the Netscape 128 bit key. You have to download the domestic version of the JSSE from java.sun.com, and use that keytool to generate the cert request. Then you should be able to get it to work. Make sure the information in the cert request is accurate tho.

Kevin, quick question on your login test. Does your application use EntityBeans to represent your users (and therefore are you calling EntityBean.ejbFind() to load from Oracle?). Or are you using another mechanism to represent users within your application? Many thanks for posting this info, it's extremely helpful! --Mark Hi all, Well, using a pretty nifty (and very expensive) testing tool, I was able to do some "minor" testing on a login process of our site. Using Orion, Oracle 8i database, and e-load test suite, here are some numbers that I got: 25 users - 15 connections in the pool pages per second - 43 pages per day - 3.75 million transactions per second - 14.5 transactions per day - 1.26 million 25 users - 30 connections in the pool pages per second- 26.4 pages per day - 2.28 million transactions per second - 8.81 transactions per day - 761333 25 users - 5 connections in the pool pages per second - 51.95 pages per day - 4.48 million transactions per second - 17.32 transactions per day- 1.49 million The test is simple. It uses the browser built into the e-test suite software and "automates" the login process of our site. I ran the test on a PIII650, with 512MB RAM. The database is running on a SUN E450 serve with 512MB RAM. The test simply sends a post submitted form with the login name and password to a controller servlet that then hits the database using a connection via the pool, and logs in the user. All logins were valid, I did not test invalid login names/passwords. Just thought I would share these numbers. Next week I will be setting up a two-server farm, using the load-balancer software that Orion includes in their download. Each server will be dual PIII550 with 512MB RAM and SCSI III RAID hd setup (Actually, they are IBM NetFinitiy 4000R units). The load balancer will run on a slow PII300 workstation with 128MB RAM (I hope this is good enough). They will be failed over and load-balanced, and I will test the performance on those and post the results here. The only thing I am not sure of is if different testing software performs about the same..or are there dramatically different results. If anyone wants me to attempt to test their site, I'll give it a go from here..but its over a T1 connection, where as my test is done locally on a LAN, so I am sure the results are more skewed.
findByPrimaryKey..what should be a primar key?
Hi all, I am a little confused on one thing..if I create an entity such as name, address1, address2, city, state, zip, home phone, fax, cell And a "profile" page shows those fields..and I can store that as an entity in the database. The problem is..what if I want the ability to search on ALL of those fields? Do I need to define the PK class with all of the fields too? I am not sure exactly to corelation between an SQL Query where I could put in a "where x = z and x2 = z2" to allow searching on more than one field, when dealing with entity beans and primary keys to pull up searches. Can someone explain how I would allow a search on every field of an entity bean? Thanks.
