AW: Entity beans never changed back to the pool.
Hello Esteban,
I posted the same question some months ago.
In this list there are several mails concerning the cache-strategy of
entity-beans in the orion-container - but unfortunately we never got answers
from the developer-team.
I found a way to flush the cache automatically.
You can use the class
com.evermind.server.administration.ApplicationAdministrator
from orion.jar in the following way (application-client or session-bean):
...
import com.evermind.server.administration.*;
...
Context context = new InitialContext();
ApplicationAdministrator admin =
(ApplicationAdministrator)context.lookup("java:comp/Administrator");
...
admin.flushEJBCache("name of your entity-bean");
...
All beans will be flushed, it works fine.
But the virtual memory of the JVM don't change (WinNT, JDK 1.3, Orion
1.4.0).
Kind regards

Betreff: Entity beans never changed back to the pool.
Hello, I plan to use Orion-Server for a big Database-Application with Java-
and Web-Clients.
I'm using Orion version 1.4.0. After serveral tests we noticed, that once a
Entity-Bean was instanced and used, it never changed back to the pool. The
number of usered instances grows and grows until I manually flush the cache
in the Console-Utility.
With this strategy, the Server will run out of memory after some time. Is it
possible to limit the number of used and pooled Entity-Bean instances ? I
can't find any parameter in the xml-Files.
Best regards
Esteban
RE: answer (maybe) RE: writing to application.log from EJB
Thanks Mike. The info on Log4J is pretty interesting, especially the ability to log to remote syslogs! That's a great facility to have if you're logging security-related events, for instance. Will send you a longer note to your internet.com address. Will send the JNDI browser servlet code with deployment info to OrionSupport asap, probably the weekend.

RE: Transaction propagation question
I think it defaults to NotSupported; also have in mind that J2EE only allows flat transactions, so, if you a a secuence Required ---> Requires New T1 T2 it will perform 2 transactions, not connected between each other, that is, if T2 fails, T1 doesn't fail autoamtically. -Original Message- From: Aziz Sharif [mailto:[EMAIL PROTECTED]] Sent: Viernes, 03 de Noviembre de 2000 18:11 To: Orion-Interest Subject: Transaction propagation question I have a question regarding transaction propagation. I took the orion primer example and modified it so that the servlet calls Hello and then the Hello Bean calls A HashCoder bean. Both Hello and HashCoder beans are stateless session beans and perform SQL. The Hello does a delete and the HashCoder an incorrect select (causing a SQLException). I was expection these two operations to happen in the same transaction, so that the SQLException would cause the delete to automatically rollback since for both these beans I specified Container managed transaction. But it did actually delete the row. So it seems they two methods were running in different transactions. The only thing I did not do is to specify the tranaction attribute to the bean's methods to be Required or anything else. I don't know what it defaults to in orion. I am using DB2 v. 6.1 as the Database, the in both beans I acquire the connection through JNDI DataSource. I configured the data-sources.xml for DB2 as follows: I am attaching the zip file containing the modified orion primer example, that can be built simply by tying ant. I would like to know how to get something like this where multiple session beans participate in a single transaction such that if any one throws an SQLException the transaction is rolled back by the container.

Just without a lot of the wizards, the jbcl (various borland db enabled tools, layout managers, etc) classes and things like group tools, or source code. With some effort you can configure the foundation to do a lot of the things enterprise does. For example, you can get the j2ee stuff from sun to include as a library (so jbuilder will browse the source automatically) and use the sun deployment tool from a menu in jbuilder. So you can see if you like the environment and then decide about the enterprise version. Which has all of the bells and whistles turned on.

RE: The way to use EJB?
Entity Beans a a representation of persistent data It may be a record in a table in a DB, or maybe something else (like an entry in LDAP)... the idea is that Entities expose themselves as object and you work with them without caring whether they're a given record in a given table in a given DB (provided by a given vendor) Usually, modelling from the Presistance(i.e. Oracle) up only brings you problems in the long run (and sometimes even sooner)-- IMHO: forget the DB, specially when you have a persistence manager as good as the one in orion.

At that time I start to wonder that perhaps we were designing the wrong way. It looks like we were designing Objects FROM Tables, and EJB is a way to create tables FROM Objects. And most of the troubles of the first project were because of that. I mean, we create objects tha represented tables, rather than tables representing objects. Any comments? -- Best regards, Rafaelmailto:[EMAIL PROTECTED]
Re: There has GOTTA be a BETTER way !!!!
Development tools like JDeveloper etc are great but they just build code. We have a generic framework that saves building all the bits of development you see time and again. We have gone along way with this with auto display, listing, add and edit forms, search etc. Plus lots of real world apps. Rapid is off the shelf customisable applications and not simply firing up Java Development Tools to start completely from scratch. Our experience comes from 2.5 years of web apps in Java and putting in reuse to save us with the boredom of repetitive work. Sorry this is abit off topic from Orion. I might add that Orion is our teams favourite J2EE server by far and we have used most of the major servers.

RE: There has GOTTA be a BETTER way !!!!
Pramati Stuido does that... takes a DB Table (if you want one), and creates either BMP or CMP entities It has a packager, and it also has a J2EE App Server + Web Server built in, for development purposes, and allows for debugging of jsp/servlets & EJBs It also is 100% pure java, so you can run it in any platform Oh, and their support is surely the best in the business It costs $1180 with a year support -Original Message- From: Keith Kwiatek [mailto:[EMAIL PROTECTED]] Sent: Viernes, 07 de Noviembre de 2003 12:35 To: Orion-Interest Subject: There has GOTTA be a BETTER way Hello, EJB's are great if you like tripling the amount of code you have to write How is everyone building their web apps with hand coded programs, or using automagic tools?

Two Orion Servers!
Hi, I have two Orion servers running on the network sharing some entity beans. Both two Orion use the same SQL server and table to store entity beans. And here is the problem! Some how the entity get cached in the application server so the other one doesn't get a fresh copy of the data! It's not a concurrency problem since even if I update an entity from server A now and 5 minutes later I read it in server B, I get old data! So any idea? Regards, Amir

RE: There has GOTTA be a BETTER way !!!!
When we initilly started to develop with EJB, we used Pramati Studio to generate our BMP Entity beans. Points to a database, you select the table and field, and it generates all of the sql code and related files. Very nice tool, but had a quirky interface at times.(But save a huge amount of time when generating BMP enity beans). Now, we usually code our EJB's by hand, but use some tools to help the process out. My favorite tool is the EJBDoclet put out by Rikard Oberg, you can get it a www.dreambean.com. It easily integrates with Ant, and saves us a ton of time and typos. It uses the doclet technology to allow us to simply insert a couple of comment tags in the Bean itself, and it will autogenerate the corresponding Remote and Home interfaces, as well as the ejb-jar.xml. We have extended it to generate some utility classes we use for access to the EJB's too. Check it out, it is pretty sweet(and free, and opensource) James Birchfield Ironmax a better way to buy, sell and rent construction equipment 5 Corporate Center 9960 Corporate Campus Drive, Suite 2000 Louisville, KY 40223

Re: Problem with build script
oops. That wasn't the right code Gauri
Forcing servlet declarations
I have several apps the share common libraries. Some apps I want to execute some servlets in the library but not others. Is there a way to keep a web-app from executing arbitrary servlets?1 Ordinarily http://yourserver.com/servlet/class will execute class as long as it is in the classpath and has no security restraints that are unresolved. I want only servlets that are declared in the web.xml file to be executed. Is there a way to do this? I tried removing the servlet-webdir attribute for the tag, but no dice. Anything else I can try? Thanks, Russ

I thought I would just add that there are some good tools out there. In particular JBuilder 4 is looking really slick... The foundation version is free and doesn't have the EJB stuff turned on.. But if you happen to be working on EJBs professionally then getting the company to drop $2500 for the enterprise version is worth it IMHO. Clearly this is lot for a non-pro to pay for a tool.. At home I'll just use the foundation version and some scripts... Works fine and don't cost nothin... later dave

There appear to be tools out there. I did a search for EJB generator in www.northernlight.com search engine, and the first site is http://www.d-a-t.com/Download/product%20info/boca-ejb.htm. I know Iplanet application server has an Iplanet Application Builder, which generates EJB skeletons. Kawa is building an enterprise edition of their IDE, but I don't know if it will generate EJB (Allaire/Jrun just acquired them).

Yes, you can access an ejb directly from JSP--at least I'm fairly sure I saw it being done in one of the examples I was looking at somewhere. I would never want to, so I didn't care about it at the time. > Am I off base here, or are ejb's a lot more work? How can people talk about > how EJB's "speed development time"?!? EJBs can speed development time for extremely scalable applications that require transactions, clustering, and other services that the container and server provide. Once you get used to bean programming--it does not take that much time to develop them at all--and it gives you very clear modularity/organization so you know where a given piece of code/functionality should go. It's definately not for everyone, though. If all you want is to whip something out really quick and not so concerned about the things EJBs give you, try some sort of rapid development framework. -joel shellman http://www.ants.com/

You are just running a web application not a full j2ee application, so you have to add an entry into config/application.xml which is the default application for orion. all you have to do is make an entry that looks like: *This is assuming that your testsite is in a directory in $ORION/applications called 'TestSite' you don't need the entry in default-web-app. or the web-app directive in TestSite.xml all you need to set in TestSite.xml is Your server.xml setting looks ok.

The way to use EJB?
Hello! This can sound a little off-topic, but is an interesting matter that we have been discusing at work. I'm currently working in two paralell projects. On one of them ( the first one) we designed the tables and used JDBC, until we decided to migrate to EJB 1.1. At that point we create one CMP EJB per table. Later we had to create BMP EJB to manage some complex relationships. The second project uses a lot of code from he first one, and the persistence need is the same ( same data). At that time I start to wonder that perhaps we were designing the wrong way. It looks like we were designing Objects FROM Tables, and EJB is a way to create tables FROM Objects. And most of the troubles of the first project were because of that. I mean, we create objects tha represented tables, rather than tables representing objects. Any comments? -- Best regards, Rafaelmailto:[EMAIL PROTECTED]

Different people have different ideas of how to design their applications meaning that the tools available today are normally works one layer at a time, i.e. One tool for EJB's, one for JSP's etcetera. However, I do think that IBM's VisualAge does a little of what you're looking for. > You can't access ejb's directly from a jsp page (like a normal bean) can > you?

I don't want to run the whole EJB sales pitch here, but basically EJB gives you automated authentication, authorization, transaction handling and persistence, among other things.

You simply can not do this. When referencing one bean from another you are essentially being just another client of that bean. And since clients can not, and should not, know anything about the current implementation, you are not able to declare which implementation bean to use. /Marcus -- Marcus Ahnve email: [EMAIL PROTECTED] Lecando AB Office: +46-(0)8-634 94 18 Sweden Mobile: +46-(0)70-462 19 18 www.lecando.comICQ#: 4564879

RE: BMP vs CMP with Orion
I just received JBuilder 4 Enterprise and I will say that it does an amazing job at EJB so far. You can connect to a datasource via JDBC and pick your tables and keys for Entity CMP. It's amazing. I'm still tweaking the deployment descriptors for Orion. Man the money you can save on Orion should go toward also purchasing JB4 Enterprise. The two together could be a very cutting edge solution. It does also have support for EJB 2.0 style descriptors Haven't tested this yet though.

Does anybody know what is new in the 1.4.2 version of orion server? kesha
RE: There has GOTTA be a BETTER way !!!!
If you take a look at all the code that Orion (and any other EJB server product) "writes" for you when you deploy your beans, and all the code that exists in the server to manage those beans, you'd see that the way EJBs work REDUCE the amount of code you have to write. EJBs are an immature technology. There are tools out there to "automagically" produce the bean code for you (see the "Enterprise" versions of the various commercial Java development tools).

EJBs can speed development time for extremely scalable applications that require transactions, clustering, and other services that the container and server provide. Once you get used to bean programming--it does not take that much time to develop them at all--and it gives you very clear modularity/organization so you know where a given piece of code/functionality should go. It's definately not for everyone, though. If all you want is to whip something out really quick and not so concerned about the things EJBs give you, try some sort of rapid development framework. -joel shellman http://www.ants.com/

Adding a site? - (2nd Post)
This is my second post for this question. Are most users of Orion only using the default-web-app site to deploy their applications? It seems like it should be a simple thing to add another site. Can someone explain to me (clearly) how to add another site to Orion? I have been successful in deploying EJBs and JSPs to the default-web-app location. But I can not figure out how to create another site. I have read all the earlier posting on how to do it but I continue to get the error: Error initializing site TestSite: No application named 'TestSite' found in the server The steps if followed were: 1) Copied the default-web-site.xml file to TestSite.xml. 2) Edited TestSite.xml Set the element default-web-app to application="TestSite" name="TestSite". Set the element web-app to application="TestSite" name="TestSite" root="/TestSite" 3) Added the line to server.xml 4) Added to default-web-app. I someone is can point out my error I would appreciate it. Also if someone does post an example (PLEASE!) be consistent with file names and site / application names. The site I am trying to add only contains HTML and JSP. There are no EJBs.

I have an application which runs fine under Windows 98, Orion 1.3.8 and JDK1.3

ejb-link
I have a problem trying to use the same home and remote classes with different implementations of the EJB class. In the ejb-jar.xml reference tags you specify home and remote interfaces. These does not say which ejb to use. It doesn't help to also specify ejb-link that should point out the exact EJB to use. The only way to change between different ejb classes with the same home and remote interfaces is to simply use one at a time. Anyone know a working example that does what I want or know anything I might do wrong? Maybe someone else that has the same problem? Personally I think it's a bug in Orion, but I hope to be proven wrong :) Billy

Hello, EJB's are great if you like tripling the amount of code you have to write How is everyone building their web apps with hand coded programs, or using automagic tools? It sure seems like there should be some sort of tool that you can just point at database tables, and have it build the jsp or ejb entity bean. AND shouldn't there be a tool that you can just drop the bean on an html template thus allowing visual access to the bean fields? You can't access ejb's directly from a jsp page (like a normal bean) can you? Any tools that will automagically wrap an ejb in a bean for presentation in a JSP?

RE: mapping a user to a group using DataSourceUserManager
The extra fields described in the API docs and the docs for orion-application.xml, as they pertain to user managers, specifically DataSourceUserManager, allow you to specify a groups table also (which can be the same as the username+password table). EJBUserManager also allows for groups. This all works just fine, I've found, for retrieval, and mapping a user to a role at login(), without having to specify users in principals.xml (which, as you say, is the whole point). I think there are problems with some of the methods, though, like addToGroup(), and getGroup(). This would affect creation of new users and adding them to groups, but for an existing user base you're OK.

I want to call a servlet from a JSP page, and assign its output to a Styring variable I assume that this could be done from a javabean or EJB as well, but I have not been able to find any documentation or examples of this procedure anywhere. Can anyone lend a hand or point me in the direction of some resources on this? Thanks, Derek AkersInternet application DeveloperEldan Softwarewww.eldan.com
Re: mapping a user to a group using DataSourceUserManager
Russ, to my understanding, user/group-to-role mapping is done in orion-application.xml (orion deployment files). Principals.xml defines users and groups in a manner unrelated to J2EE roles and is thus comparable to the user base you have in any other datastore. regards, Christian - Original Message - From: "Russ White" <[EMAIL PROTECTED]> To: "Orion-Interest" <[EMAIL PROTECTED]> Sent: Monday, November 06, 2000 4:57 PM Subject: mapping a user to a group using DataSourceUserManager > I have spent the morning looking through the archives and not really found what > I am looking for. > > I found that I can grab username and password from the DataSourceUserManager > just fine, but I have to map the user to a group manually still with > priciples.xml. > > If this is the only way to do this then it is a real drag, and really makes it > almost useless in my book. > > Is there any way for me to grab a user's group from DataSourceUserManager? > If so what is the property name? > If not what are my other options? > > Thanks, > Russ > >

RE: BMP vs CMP with Orion
I guess I'm using neither. The clue is that, when you stick to the rules, you have to write the minimum one panel and one table per dataobject as all the access to the properties is done via methods and each of those methods is specific for the dataobjects (e.g. getName(), setName(x)). When you have a lot of dataobjects that is a bore. The 'pattern' I'm using abstracts away (= marketing speak) from the clean OO model. The generator generates standard bean access (getProperty(index), setProperty(index, x) and by using descriptors for the dataobjects and its relations is it possible to generate default screens. Something you would most likely use reflection for when that was possible. Using reflection has two problems: - It does not work with Orion. - It works only on a per object basis. You could solve those by adding on the client side wrapper objects that implement Just-Another-Layer. You can use reflection for that layer and if you device you object in a clever way (using clever naming patterns) you -can- use reflection. Why the complex stuff and not generating the tables and the panel. Well, in the system I'm using I plan to implement the option for users/systemmanager to tailor their screens. You can do that when you generate screen on the fly, you can't when they are already compiled. It is a bit of an excercise but I am always strongly in favour to use as less as possible code to build your final system. A lot of bugs stem from silly mistakes: the less code, the less silly mistakes. And if in the above generator there is a silly mistake it is reproduced in a lot of places: more chance to be discovered. I guess the same model could be used for dynamic creation of HTML.
