Error in ORList (Re: byte array OR mapping...)
Yes I know that a byte is a primitive, but byte array (byte[]) is an object.
In my Entity Bean, this array represent a graphic (a jpg), one of my entity
bean can have more than one graphic (I represent it now with a List of
Graph).
I changed my EJB to :

All these errors in Graph_ORList20.java are just because Orion generate [B
insteed of byte[], so the compiler don't understand it... My question is :
Can I write my own Graph_ORList and tell Orion where it is or how can I
correct this error ? (Is this an Orion bug ??)

Subject: RE: byte array OR mapping...
The '[B' is the String returned when I do byte[].getClass().toString()
I don't think you want to do that. Firstly, a byte is not a class.
byte is a primitive like int, float, char, etc. which are not classes
in Java (maybe you are a Smalltalk programmer?).
Second, getClass().toString() isn't correct; you should have used
getClass().getName() to get the name of a class. A Class is an
object, and toString() usually returns a serialized version of
that object (usually, not always).
You should probably take your byte[] and place it in a class that
implements java.io.Serializable. Most of the database mappings
support placing that into a blob:
type-mapping="java.io.Serializable" name="blob"

ejb-ref and resource-ref question
Title: RE: -- Arved -- Can you please help me with servlet authentication? Hi guys, Being relatively new to J2EE I have a question concerning ejb-ref and resource-ref tags used in the configuration XMLs (ejb-jar.xml) Is it quite normal and J2EE standard that every EJB/Servlet/etc that wants to call the same EJB needs to have its own (and SAME) ejb-ref tag in ejb-jar.xml/web.xml/etc? ejb-ref defines the location in JNDI that is used when theclients 'lookup' the EJB Home. Could a commonly used EJB/resource component be published in JNDI globally? Or do I have to repeat theSAME ejb-refs couple of times in the XMLs? If this is truethen it makes deployment and configuration quite complex, redundant and subject to hard maintenance. Please let me know if we have alternatives to the above case. Thanks, Tibor
Re: pop3.jar again
Actually the last part of the String it is not "file_path" (in the specs) it
is "folder_name" like "INBOX" or something (in fact the Sun implementation
for pop3 doesn't support another folder except INBOX). But my advice is to
_not_ use it instead obtain the folder using something like:
session = Session.getInstance(props, null);
// store = session.getStore(new
URLName("pop3://username:[EMAIL PROTECTED]")); //this is the right
way !
store = new POP3Store(session, new URLName(Constants.MAIL_URL));
store.connect();
folder = store.getFolder("INBOX");
if (folder == null || !folder.exists())
log.pError("Invalid folder");
else
folder.open(Folder.READ_WRITE);
Again all you have to do in order to make the above code work is to put
pop3.jar in orion/lib directory.

Sorry I mis-read your email. I now have added activation.jar, mail.jar,
and pop3.jar to the orion.jar manifest file. These files again reside in
orion_root/. I still get the same error. As far as the code goes
"pop3://cucu:[EMAIL PROTECTED]", this is a dumb question but what is the
break up of this String. ie: is cucu a server name or password followed by
:email to check?
I believe that URL is broken down as follows:
provider://username:password@provider_host/file_path

I had posted something similar as a bug (sorry, can't recall the number; if you

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;
}

Workaround found - Re: Error in ORList (Re: byte array OR mapping...)
Hello again,
I found a workaround for this bug : I just changed my Graph class to
public class Graph implements Serializable {
public Object datas;
public void setDatas(byte[] datas) {
this.datas = datas.clone();
}
public byte[] getDatas() {
return (byte[])datas;
}
}
And it works fine !!

Re: Huge amounts of entities, no pooled instances
I'm new to all this, but from looking at your code the only significant
difference I see is that the second try block has a finally after it and the
first one doesn't. Perhaps it's a bug [in Orion] and perhaps not, but maybe
it doesn't passivate without a finally? Or maybe it needs a catch to notice
that it needs to passivate. I just see that the VERY first try block in
your code doesn't have either one after it.

URGENT-Server crashes or locks up
We are using Orion merely as a servlet server (no ejbs) and we are hosting surveys (forms, questionaires) in it. We have built the validation / routing logic into the server using rhino (js.jar) and we have our own proprietary data store. When we go to test the server under stress (as much load as we can get it to take simulating 30-50 users hitting it as hard as they can) after about 14 hours using hotspot (Sun's server VM) and 112 hours using classic it either crashes or locks up. The hotspot VM dies with and internal error and the VM just quits. I have seen this VM allocate over 3000 threads. The classic VM runs Windows NT out of virtual memory. (lots of threads here to) Has anyone seen anything like this ? We are a software development company and are using many different configurations so far the servers we ahve tested are Windows NT4 (with SP 5 or SP 6) and W2K (both server versions) and we are using orion 1.3.8 and js.jar (rhino 1.5). I don't think we can come up with a "little test" to send to Sun as bug against their VM - at least Orion is needed and that's not little. Does anyone have any ideas about how to make our server stay up under stress. Nate

Re: Huge amounts of entities, no pooled instances
I am not quite sure, but for each entity bean two objects are always
created:
- remote EJB object
- object with your bussines logic.
I think that only second one is subject to pooling - so maybe you can be out
of memory because of large amounts of remote instances. This problem you are
facing to brings me again the question about the sense of entity beans.

Inner classes in JSP don't work
Hi, some weeks ago i found a message in this newsgroup that the bug with inner classes in JSP is now fixed. I am currently using 1.4.4 and it seems that this bug is either not yet fixed or it is back again. I tried also with 1.3.8 and 1.4.4, in all versions I was not able to get a inner class in a jsp file working. Has anybody got the same problem? Should I post it to bugzilla? I am not sure, because Magnus said it was a bug in 1.0rc1 but it fixed now. /Thomas -- | /Thomas Hertz | [y] hybris GmbH | Software Engineering | | [EMAIL PROTECTED] | Schwere-Reiter-Strasse 35 | tel +49 89 306697- 0 | | www.hybris.de | Haus 16, D-80797 Muenchen | fax +49 89 306697-99 | | pgp fingerprint: D070 5D86 BE2D C3AF E2CC D2D8 C29A 7F68 7407 629E |
Re: DataSourceConnection not closed
I don't see a wait-timeout property in the orion-ejb-jar.xml dtd. Is it added in a version after the one I have (1.3.8)? All I see is call-timeout and timeout in Session beans, and call-timeout and validity timeout in Entity Beans. -Dan Marcus Ahnve wrote: > "Juan Lorandi (Chile)" wrote: > > yes, I've been complaining about this issues starting a month ago... > check bugs #161 #170 for more info > > nobody from orion replies, and it's a shame, because I cant license > the products until I work my way around these > > Anybody performing a DoS attack on any Orion Web Site will effectively > crash the server Bug #170 was filed due to the fact that the server chrashed and burned if it ran out of connections. For some weird reason, it seems to be very CPU expensive to wait for a connection. However, now that you can specify the wait-timeout property we can keep the server alive, with tons of timeouts though. I've set the status of #170 to fixed, since the immediate problem is fixed. Now, for "DataSource not closed", that's a whole new story, but I believe that there are other reports in bugzilla regarding that topic. FYI, we not only get it due to timeouts, but when testing our app against Hypersonic's in-memory db too. No clue why. /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.com ICQ#: 4564879 -- Daniel G.

RE: A newbie question - problems with JDBC-connection
If you don't mind..can you help explain to me how you even got this far? I just installed Oracle Personal Edition, and I would like to get Orion to pool connections, use a DataSource, and so on. I don't know about using entity beans yet..I don't think EJB 1.1 entity is powerful enough yet..but 2.0 should be. Until then, I only have 5 tables to work with, which I will use SQL for in the EJB session bean. So if you could possibly explain what JDBC type 4 driver you are using (where you got it from.URL?), how you got Orion to use it as a DataSource instead of the Hypersonic SQL one it defaults to, and so on...I would be much appreciated. Thanks. Hi! I am pretty new to applicationservers and thus trying the grasp the nuts and bolts. I have just finished a sessionbean (via a servlet) which connects to a database and reads a specified table. Everything works fine the first time a run my servlet. But the second time, I get no connection, either of the pool or a new one. I run my example, as recommended, by ejb-location="jdbc/DefaultEJBDS" and I am using classes111.zip from Oracle. Can anyone help with this problem and also explain the principals behind what is happening below.

Hello Sven,

interesting mails discussing this problem.
Ok, I found the workaround in the mailing list:

Context context = new InitialContext();
Object o = context.lookup("java:comp/Administrator");
ApplicationAdministrator admin =
(ApplicationAdministrator)javax.rmi.PortableRemoteObject.narrow(obj,

snip
admin.flushEJBCache("name of your entity-bean");
snip
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.

RE: OFFTOPIC: Making a page expired
Question..does this solve the problem of the BACK button going to the
server? I have this problem where if I "control" caching, thus wanting to
force the browser to always go to the server, if the user hits BACK, they
get the infamous "this page has expired from cache..please refresh your
browser..." and that is just not acceptable for a professional site.
Especially given that fact that most users don't know what the hell this
means, or why it happened.
So, will this CACHE-CONTROL setting eliminate this problem and ALWAYS force
the BACK/FORWARD button to use the server page, instead of anything in
cache?
Thanks.

RE: OFFTOPIC: Making a page expired
No - not in my experience
For various reasons, a successful post (usually saving some data) in my web
app causes a redirect to occur to display the newly saved details.
In my case, 95% of the time the user hits the back button the page will
reload properly because the URL wasnt loaded from a form post (thanks to the
sendredirect).
On the few occasions that URLs are loaded from form posts (eg login) I still
get a "page has expired" error. I can live with that.

Just a note that I have heard many negative comments regarding using
