Re: java.lang.OutOfMemoryError in Product Application
This is a known bug. A workaround was posted a while back. I have since
moved to another company and dont have an installation of orion here so
Im going from memory here. there should be some class in the orion API
like com.evermind.Administrator which has a function flush() (static I
believe) which flushes theentities from memory.

Huge amounts of entities, no pooled instances
Yesterday I posted a question about batch updating in Orion. Orion is
creating huge amounts of instances of my entity without pooling.
Someone mentioned that my updates possibly would be inside the same TX.
Actually I'm using updating 2 tables, in one table, There is only 1
entity ised and it's pooled, the other one creates huge amounts of
entities. (One for each line in my file, there are some 20 lines to
each file and sometimes a Deadlock occurs due to an
OutOfMemoryException).
I have now set the Tx attribute to my update and remove methods to
RequiresNew, but still one bean is creating huge amounts of Beans while
the other is pooling.
Here's the updater method of my session bean:
public boolean update(ContaEncerradaModel m, String nome){
boolean result = false;
try{
try{
Ccf ccf = ccfHome.findByPrimaryKey(new CcfPK(m.getCgcCpf(),
m.getBanco(), m.getAg()));
ccf.setQt(m.getQty());
ccf.setDate(m.getDate());
result = true;
} catch (FinderException ex){ // if we cant find it we need to
create it
try{
ccfHome.create(m.getCgcCpf(), m.getBanco(), m.getAg(),
m.getQty(), m.getDate());
result = true;
} catch (CreateException exc){
result = false;
}
}
try{ // no need to set result in this block, since we anly want to
know about ccf
//
here's where only one instance is created, it's activated and passivated
constantly.
the CCF part however keeps creating instances without passifating.
//
nHome.create(m.getCgcCpf(), nome);
} catch (CreateException ex){ //this probably means we already
have the name, so forget it
}
} catch (Exception ex){
System.out.println(ex.toString());
} finally {
return result;
}

ApplicationAdministrator admin =

and I've added a finally block to my try{}catch{} blocks.
This seems to work, the bean is passifating now and the application uses
only 1 pooled instance of the bean. However, IMHO this is something the
container should be taking care of for me.
I'm taking a look at Bugzilla to see if there is any report on this.

Used Instances
In Orion console, what does 'Used Instances' denote? I'm doing batch updates to a database (about 20 daily) and about three quarters on the way, Orion console shows some 59000 used instances of my entity bean somewhere after that, my application crashes with a DeadlockException and shows that the nested exception is an OutOfMemoryException. I'm at a loss here, does Orion actually keep these 59000 entity beans in memory ?? Shouldn't these be pooled ?? (Pooled instances shows 0!!). I'm currently testing the application and would like to know if there's any way to have these beans pooled. The app that does the batch updates is a simple class, it reads the lines in a file and then calls a session bean (stateless) through either of two methods (update or remove) update checks for excistence of the entity, if exists, it sets some values, when a FinderException gets thrown, it calls ejb.create(). remove finds the bean and calls ejb.remove(). I read in the specs(9.4.1): The container can choose to passivate the instance (...) Th container invokes the ejbPassivate() method when the container wants to disassociate the instance form the entity object without removing the entity object. I've been printing some output to stdout telling me when a bean is activated and when it's passivated but sofar as I can see, ejbPassivate() is never called.

Re: Anyone using Orion in production? [long]
my personal opinion on this is that evermind should deliver source (while retaining full rights on enhancements and bug fixes) with the product to eliminate that risk. other commercial projects like orbaccus (http://www.ooc.com) have shown that they still make a lot of money despite shipping source for more than five years now. I'm sure about 80% of the bugs our team has reported would have been fixed by us immediately or at least would have been accurately described to the line of source code that has to be changed. I've brought this up to karl and magnus but they don't want to do this and it simply is their baby and therefore their decision (they probably think I'm either a parrot or insane, repeating the same stuff over and over again ;-). Well you're no parrot and neither insane. I agree wholeheartedly. Before moving to Java I did a lot of development on Borland C++ Builder which ships with full source code to the vcl libraries. Serious bugs where easilly found by me and other developers, reported and corrected. It's lot's easier to report a bug if you can see the source code. However I can sympatize with Karl and Magnus. EJB is a very new technology. Shipping the source makes it relatively easy for the competition to copy the product which of course is the downside. But I think shippingg the source would be for the better of the server. Nobody is perfect and if all of us have our hands on the source lots of those silly bugs should be fixed in much less time. Having to submit a testcase makes for a lot of effort on both sides since we have to create a testcase which has to be recreated by the orion team and tested. Most of these bug however would simply appear running your app through a debugger and jumping into the orion source. any other orion users have an opion on that?

What's the trick, or am I stuck with BMP (as I suspect is the case)? Using auto incrementing fields in EJB is not very usefull since they may map to databases not supporting such features, it's just like stored procedures. They might seem to look like a good idea, but it just makes the application much less portable. Orion includes an EJB which can generate a unique id for you, it's in counter.jar (I think you can find it in the news app). However if you really have to use an existing DB, you're either stuck with using BMP or you could write an entitybean (CMP) which only does the updates for you and may delete te bean by calling remove on the bean and a stateles session bean that handles the insertions for you. sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==

more of a OR problem -- I have a CMP field (that happens to be the
primary key) and I want to control its relational representation. And
with all the nice OR stuff in Orion, it must be possible. My only
constraint is that I have to adhere to EJB1.1.
You'll need that public string for cmp to work. The primary Key class
should contain the primary key field in your table (as a public field)
so oruion can manipulate it. Take a look at yeh EJB sprec, section
9.4.7.1 and 9.4.7.2

You might want to try to return from your method ;-) Forwarding a

Orion has unofficially been supporting many of the latest J2EE specs (probably the first independant vendor to support EAR files). BEA and Orion are currently the market leaders in EJB 2.0 compliance. Both vendors have had EJB 2.0 beta features for months now, and are close to full support. * Ease-of-use. Again, BEA and Orion get top marks here. Installing BEA application server on a Unix machine has been a simple process of unzipping a file. Deploying a complete J2EE application in Orion requires adding an EAR file and two lines to the Orion config files.

Most people seem to be using them for prototyping and small scale projects, that I know of... It's quite a new technology, so there are hardly any big projects running.

that can use JOnAs and Orion as the container.
JOnAs's JNDI does not support java:comp/env
at the client level.
Client program: For example:
Context context = new InitialContext();
Object homeObject = context.lookup("java:comp/env/BankHome");
This won't work in JOnAs. Instead I have to write this:
Context context = new InitialContext();
Object homeObject = context.lookup("BankHome");
Looking at the ejb1.1 specs, lookup("BankHome") is non-standard. EJB
should do lookups relative to java:comp/env.
You could however store this string as an evnironment property for your
beans, when deploying on JOnAs you would store "" and on an ejb1.1
clmpliant server you would store "java:comp/env/"

Doubts on finder methods orion-ejb-ar.xml
I have a couple of doubts concerning the finder-method tag. specifically, I would like to implement a query like "select * from table where field LIKE '%value'" Considering I have: cmp-field-mapping name="_fantasia" persistence-name="FANTASIA" / in my orion-ejb-jar.xml. and the docs tell me: finder-method partial="true|false" query="$1 = $myField AND $myOtherField 5" I suppose (not really clear in the docs) that $1 is the value passed to the finder method and $MyField is the persistence name, in the above example FANTASIA and not _fantasia. Is that correct? in this case can I create a query like: finder-method query="$1 LIKE '%' + $FANTASIA + '%'" Sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
Wap url rewriting
In the code below, Orion automatically rewrites the URL, creating a
wrong link in the celphone. Is this rewriting default behaviour, and how
can i undo this?
% if (checkBean.getContas() != null) { %
a href="#contas"contas encerradas/abr/
% } else { %
sem contas encerradasbr/
% } %
% if (checkBean.getTelefone() != null) { %
a href="#telefone"Informações do tel/abr/

Orion Sybase
I just installed sybase and after updating the data-sources.xml I redeployed what I'm currently developing. While deployng, orion started autocreating tables, which is ok with me, except for th fact that it is autocreating in the wrong database. Here's the relevant part of my database xml data-source class="com.evermind.sql.DriverManagerDataSource" name="CEP" location="jdbc/cepDS" xa-location="jdbc/xa/cepXADS" ejb-location="jdbc/cepDS" connection-driver="com.sybase.jdbc2.jdbc.SybDriver" username="sa" password="" url="jdbc:sybase:Tds:brvip.com.br:7100/CEP" inactivity-timeout="30" schema="./database-schemas/sybase.xml" / data-source class="com.evermind.sql.DriverManagerDataSource" name="BOLETO" location="jdbc/boletoDS" xa-location="jdbc/xa/boletoXADS" ejb-location="jdbc/boletoDS" connection-driver="com.sybase.jdbc2.jdbc.SybDriver" username="sa" password="" url="jdbc:sybase:Tds:brvip.com.br:7100/BOLETO" inactivity-timeout="30" schema="./database-schemas/sybase.xml" / and a part of my orion-ejb-jar.xml: entity-deployment name="User" location="User" wrapper="UserHome_EntityHomeWrapper9" table="Users" data-source="jdbc/boletoDS" primkey-mapping cmp-field-mapping fields cmp-field-mapping name="cgc_cpf" persistence-name="cgc_cpf" / /fields /cmp-field-mapping /primkey-mapping cmp-field-mapping name="_ie_rg" persistence-name="_ie_rg" / cmp-field-mapping name="_nome" persistence-name="_nome" / cmp-field-mapping name="_fantasia" persistence-name="_fantasia" / The tables to be autocreated are in the boletoDS. However the tables are created as if I u used: url="jdbc:sybase:Tds:brvip.com.br:7100" for an url instead of url="jdbc:sybase:Tds:brvip.com.br:7100/BOLETO" Does anyone have any experience with Orion sybase ? What might it be that I'm missing here? Sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
Re: SV: Orion Sybase
[EMAIL PROTECTED] wrote: Put the datasource of the database you want the tables to autodeploy in first in the datasources-xml. Or remove autocreatetable support and deploy, then edit orion-ejb.jar.xml to point to the right datasource, then enable autocreate option and redeploy again. Should work just fine :) And so it did ;-) The three words that apply to me are STUPID, STUPID and STUPID ;-) I had created the db boleto (no caps) and pointed to BOLETO (all caps). I suppose this is a bug in Sybases JConnect.

autocreating tables
When orion autocreates tables, string fields are always represented as char(255). How do i change this behavior so it will create for example: String name as char(25) String firstname as char(20) String zipcode as char(8) etc. Sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
Re: Benchmarks
Lawrence Fry wrote: Christof, I read this article, and the comparison in this benchmark is between php, perl and java. The benchmark is not intended to compared j2ee application servers, and as noted in the article, only includes "toy" applications like hello world. The conclusion of the article is that java is as good or better than php and perl. However, lets make some comparisons. Orion is about 2% faster than Resin, which in my book is nearly the same. However, Resin is not a j2ee server, and uses non-j2ee ejb protocols. Most of us use Orion for the ejb support. Besides, Both where tested on JDK 1.2. And the Orion version was 0.7.someting.

You just need to create the directory structure (or ear and war files), edit the proper web-site files, and as the last you edtit Server.xml. As soon as you save server.xml, Orion will start to deploy the application. Sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==

Re: How do you like Orion?
2.3+..not sure about the new 3.0 version) ). It got shot down simply because our "big boys" felt they were too small of a company to rely on being around in a couple of years. Despite the fact that I already had our site running on it (not production..but on my local box) and it was extremely easy to configure, they put WebLogic, WebSphere and Oracle App Server on the list..that was it. Even though Orion is several times faster than WebLogic, we would rather spend $150k on WebLogic (cluster..$15K per cpu per server) than $10K on Orion to do the same thing..yet better. Go figure. Hehehe Isn't it amazing. I had the same discussion with my partners some financial backers for our ptoject relating to my choice for databases. I've chosen for DB2 for various reasons, but my main reason being that it's been on the market for more time than i've been using computers, because of IBM's heavy support for JAVA and it's scalability (I've been able to use it quite well even on a win 98 box with only 32 megs of ram) Oracle, our other choice, I've personally not been able to install, neither on a linux box nor on solaris or nt. It cracked up on some 99%. I had to defend IBM DB2 (US$ 26,000) agianst Oracle (On our dev machine would be around US$250,000) based on the difference in price."With that difference, there must be something wrong". Orion is a great tool. It's the only app server I know, but all I hear of others such as weblogic, iPlanet is that they are not 100% j2ee. What's the use of having a j2ee standard and having an appserver that does things different. Luckily I'm in the position to decide on what to buy when the time comes. I will never fork over US$150.000 for an appserver when I might just as well pay only US$ 1500 for something that works *at least* just as well.
