ORION running under Solaris Environment
I want to build my development department with Orion under Sun Solaris. I want advise about: * How it should be implemented: one server with Orion inside it and terminals running that instance of Orion or Orion installed in all of the workstations * What are the hardware requirements in both alternatives( workstations and server I'd prefer if you are concret, I say, especific machines like Ultra 1,2 ... workstations like Sparc 20,... and memory requirements...

HARDWARE FOR J2EE apps
I would be very gratefull if anyone with experience tell me what it's the appropiate hardware to develope ejbs, servlets and jsps, and what it's the appropiate in order to run an app with a great load of concurrent users. I wanna know your opinion about what to choose Unix(solaris,HP,..) or Win (intel) for both development and real app. TIA. - David Sierra Fern ndez -- -- Sierr@ --
LDAP
Hi all, I know that a ejb can make a request to an URL, send an e-mail, and manage other actions defined in methods of its superclasses. I want to know if it is possible to make a request to another port different to http port or STMP port?. I would like to make a request to port 389 (ILS). This port is the default port in almost all LDAP servers. If it is not possible, I will have to use ASP. Any ideas would be appreciated.

In web.xml, nested in servlet tag you have a tag called load-on-startup where you specify the priority number which your servlet will have. a value of -1 will not load on startup your servlet.

Re: Begging for Help: EJB Deployment in Orion Server 1.0
First of all you have to create a J2EE directory estructure: application --- META-INF/application.xml | module.jar | module.war and then follow the instructions in Orion docs "How to deploy an app" You have to create yourself application.xml. Read in docs about the estructure of this file but basically you only have to declare the modules you use in the app. Hope this helps or at least push you a bit. - David Sierra Fern ndez Ingeniero Tecnico de Telecomunicaci¢n AULA RETECAL (CEDETEL) Universidad de Valladolid Campus Miguel Delibes E-Mail: [EMAIL PROTECTED] 47011 Valladolid (SPAIN) -- -- Sierr@ -- On Mon, 7 Aug 2000, Ray Harrison wrote: Hello: (I am quite new - forgiveness and patience please!)

Suppose the server had not been busy for quite a while. Under these conditions Orion would have written all its entity beans back to the DB and removed them from memory. If you now empty the DB, then all the entity beans are gone (in the sense that trying to find one from its primary key will fail). If the server is extremely busy when you emtied the DB, then all the entity beans may well have been in memory, and they will get recreated in the DB when Orion writes them out. Hope that helps.

Re: AW: Update: Performance Scalability
Hi Tom, I would like to know exactly the diference between ejb-location and pooled-location. ...and other thing...but I thing that Orion team is the only one who can answer me... How does ORion manage the connection pools??? I mean that Orion only let you set the max-number of connections but I want to know how many connection does it create at the begining, the number of connection that it creates when the initial ones are busy, if these extra connections (out of initials) are destroyed after a certain time whithout using them, an so on This is very important because imagine that your application has a lot of clients and inmediatly you start the server you gonna have 200 hundred clients.. in this situation it cuold be great tha the server creates at least 250 connections at start. Now imagine that you have a hot peak of affluence and you run out of connection (250 all busy) you will need more but because the extension of your application, it would be a great idea to create extra connections but in groups of 25, and destroy or not destroy them in a timeout depends on your decision. All this with the security that they will not be over a certain number of connections that you set and could cause a fall in your database. Now imagine the opposite situaion, you have a small application whith perhaps only two clients connected to the DB at the same time, it would be a lose of resource if your server creates 100 connections at start, the best could be to create only 2. And if this connections are busy it would be awfull to create a extra group of 20 connections at the same time because probably youwill only need one or two extra connections. Here you can see how you can take advantage of connection pooling. I'm sure that Orion manages the connection pools eficently but If the problem was the connection pools and weblogic let you set all this values, Have you thought that perhaps your configuration in weblogic is not the best for your applicaction? Repect to the Orion team...It would be very interesting to know something more about how Orion manages connection pooling. THANKS ALL. - David Sierra Fern ndez E.T.S.I.

This issue has received a lot of traffic on this list, but I have yet to hear anyone for the Orion Team explain either a) what we're doing wrong to cause this error, or b) that it is indeed a bug in the software and it will be fixed in release 1.x.

DEPLOYING A PRE-WRITTEN BEAN
Imagine I want to deploy a bean that I've packed in a JAR file. I know how to deploy a complete application but what should I do to deploy an application with only a JAR file I think the only thing I gotta do is to insert in server.xml the line: application name="myapp" path="../applications/myapp.ear" / Am I oblide to make an ear file to deploy my beans??

EJBs at runtime
*I want to know if it is possible to deploy applications with the server running. *and... undeploy application without stopping the server. *Could be possible in Orion stop a single bean or a single jar?? or do we have to stop and deploy the whole appplication???

Connection POOLs
I've seen that you have the posibilty to bind to the JNDI a pooled version of your database. Is this a connection pool? If I'm correct... where you can configure the features of the pool: min connections,capacity increment. If it is not possible to configure I would like to know how Orion manages this kind of issues.

Connection Pools 2
I missed something. The tag max-connections refers to max number of connections in a pooled version or in a default version If it is in a pooled version, How many connections does Orion create at the begining??

OBJECTS IN ENTITYS
I have a doubt: I have an enity bean but I want that I field of that entity to be a complex object.

PORTABILITY PROBLEMS !!!
I tried to deploy ATM example in Sun's J2EE implementation server, but it didn't recognize ear file. I tried to create the ear file mayself but when I tried to include the war and jar files, this last was also not recognize as a valid file. Then I tried to create both files begining from the .class files but It does not work anyway. For last I tried to compile again the classes but I got the following error: AccountOwnerManagerEJB.java:8: Package com.evermind.security not found in import . import com.evermind.security.*; ^ UserManagementSessionEJB.java:7: Package com.evermind.security not found in impo rt. import com.evermind.security.*; If the standard file is the jar, Why Orion include especific files in the code?

RE: PORTABILITY PROBLEMS !!!
Thank you. I agree with you in the power of that API, and now I understand the concept of this API. With it we can create users and groups dinamically from the inside of the applications without the need to edit the deployment descriptor or using an administrive server console. In that way... a good approach to compatibility could be to write the application as normal and then write a class which implements the security API so if we want to move to another server, we don't have to rewirte the beans and we only should rewrite the secutiy class with the implementation of the security API of the new server.

In my experience this is the biggest problem when trying to develop portable applications. The Orion UA API is great (excellent, easy to use and very well structured once you work it out!) but it is non standard - all containers have their own API. If you want portability, roll your own user management API (but this is a pain as it won't hook nicely into app server functions). Such is life on the edge.

THREADS
My team had a problem some time ago with another server, and I want to know if it is a problem of that server of if it is defined in that way at spec. The situation was: We create a very simple entity bean in which we implement a method that drives us to a infinite loop. We create an instance of that bean and we call the create method.. at this point we call the test method (loop) and then we try to create another instance but the bean didn't not allow to create another instance even from another thread. I consider normal that a server blocks an instance that is being used, but to block the entity bean itself... I consider this behaviour excesive. Is a matter of that server or is in this way at spec? If it's normal, what happen if I have a method that last 2 seconds to compute? would i have my entity blocked during this whole time? THANKS. - David Sierra Fern ndez E.T.S.I.

Re: Easy deployment of .war files?
YEs Dorwin, it's very easy. If you hace a complete application in a .war file, you only have to follow the steps in "Hot-to setting up an Application" in Orion docs, that implies to write a couple of lines in two property files. But the most important thing is that you have to bear in mind that in those war files that you find in Internet, there shouldn't be any property particular for any other server that orion. In your war files there only cuold be standard properties and orion proerties. You can read "web-application.xml" and orion-web-application.xml" in orion docs. The same to move the war files in Orion to other servers, you have to eliminate the specific properties in order to make the war work in other server. - David Sierra Fern ndez E.T.S.I.

Re: Problem running JSP files
Try this... You also have to include your application in orion/config/server.xml: application name="webstats" path="../applications/webstats/" / and include your application in that directory. Remember that "path" is the physical route to your application, meanwhile "root" is the virtual path that you have to write in the URL. - David Sierra Fern ndez E.T.S.I.
