Stateful Session Bean and HTTPSession
Hello, I develop a web application where I use a stateful session bean for my Acl management. When HTTP session is created, I create a bean instance and cache it to the session, so my servlet and every JSP can use it. When the user logout, I invalidate the session and remove my bean. But if the user close the browser without logout or if Orion crash and is restarted, the bean instance is not removed... I set a session timeout of 7200 sec. in my orion-ejb-jar.xml, is the bean removed after this time if unused ? How can I clean these "phatom" bean's instance ? Thanks Laurent Cornelis

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 :
public class ResultBean implements EntityBean {
[...]
public String id;
[...]
public List graphs;
[...]
}
Here is my Graph Object :
public class Graph implements Serializable {
public byte[] datas;
}
And in my orion-ejb-jar.xml :
cmp-field-mapping name="graphs"
list-mapping table="graphics"
value-mapping type="ubiquity.rapids.ejb.result.Graph"
cmp-field-mapping

/cmp-field-mapping
/value-mapping

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 ??)
Thanks

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"

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 !!

I had posted something similar as a bug (sorry, can't recall the number;
if you
want I can try and look) and received a message several days ago that it
had
been fixed in 1.4.5. Perhaps, when that version comes out your error will
also
go away.

byte array OR mapping...
Hello,
I have an Entity Bean :
public class ResultBean implements EntityBean {
[...]
public String id;
[...]
public byte[][] graphResult;
}
The graphResult field is an array of byte arrays. I want it to be stored as
a list of BLOBs. Here is my mapping for this field (orion-ejb-jar.xml) :
cmp-field-mapping name="graphResult"
list-mapping table="graphics"
value-mapping type="[B"
cmp-field-mapping
fields /
/cmp-field-mapping
/value-mapping
/list-mapping
/cmp-field-mapping
The '[B' is the String returned when I do byte[].getClass().toString()
But when I deploy :
Error compiling file:/C:/orion/applications/rapids/rapids-ejb-result.jar:
Dependent OR class [B cannot be abstract unless the ejb-jar.xml has a
dependent tag for it
What's wrong ??? Can someone helps me ??
Thanks

Re: JetSpeed
For me, putting the Jetspeed jars in /orion/lib gives me the following error when calling http://hostname/servlet/jetspeed java.io.FileNotFoundException: /tmp/turbine.log (O sistema não podelocalizar o caminho especificado) It's normal, turbine.log MUST exists when you launch Jetspeed...

Re: EJB classpath problem
Your solution will surely works but I don't want to mix my jars with Orion jars... It is really i^mpossible to specify an additional classpath for EJBs in Orion ? Thanks anyway ;) Laurent - Original Message - From: wim veninga To: Orion-Interest Sent: Wednesday, October 25, 2000 3:56 PM Subject: Re: EJB classpath problem Hi Laurent Where is your rapids-util.jar file located. I would suggest that you put this in your_orion_dir/lib. I had the same kind of situation with cloudscape (database) and orion. I have a couple of objects that need to be stored in cloudscape but cloudscape couldn't find it. But i had the classes in one of my ejb-jars.
