java.util.ConcurrentModificationException
Hello everybody, I recently switched over from Apache Tomcat v3.2.1 to Orion v1.4.5. I deployed an application (that I had developed with Tomcat) using Orion and did the necessary configuring. The application works fine until the point when I logout. Tomcat never gave any trouble, but Orion keeps throwing a java.util.ConcurrentModificationException. This exception occurs when I remove all the attributes in my session object. Can anybody tell me why this happens and how to remove it? Thanks and regards, Arun Jayaprakash. __ Do You Yahoo!? Yahoo!

PetStore - Session State in a Cluster
Hi, I have the (J2EE Blueprint) PetStore application clustered on two Orion instances running on the same machine. When I connect through the LoadBalancer, I can see my session state get replicated across the two nodes. When I kill the primary node, the load balancer automatically connects me to the secondary node and takes me through the rest of the shopping cart experience, however any items I had in my cart (ie. Session state!) aren't there anymore. I know that for clustering to work, objects should be Serializable AND placed in the session/servlet context for it to be replicated. So my *real* questions are: 1) I haven't dived into the PetStore code - but is this a design issue with the PetStore or do I need some configuration pointers? 2) Has ANYBODY got PetStore working properly in a Clustered environment where you can kill the primary server and continue shopping (with your existing cart) on the secondary node? My Environment:Win2K, JDK 1.3, PetStore 1.1.2, Orion 1.4.5 NB: The SessionServlet example works FINE for me. When the primary goes down, the secondary node picks up with the same counter number as before the failure. _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
Object as a parameter in a CMP-Finder
Title: Object as a parameter in a CMP-Finder Hi, is it possible to declare a java-Object as a finder parameter? The container should have access on this object by java-methods. For example I would like to do following in orion-ejb-jar.xml: ... finder-method query=$1.getName() = $bean-attribute method ejb-nameTarifBean/ejb-name method-namefindByAnbieter/method-name method-params method-paramnet.interway.project.ValueObject/method-param /method-params /method /finder-method ... In weblogic e.g. you would define a so called finder-expression: finder-query![CDATA[ (= $0 bean-attribute) ]]/finder-query finder-expression expression-number0/expression-number expression-text![CDATA[@0.getName()]]/expression-text expression-typeString/expression-type /finder-expression Can I do something similar in Orion?

RE: PetStore - Session State in a Cluster
My guess is you stumbled upon a mismatch between the servlet and jsp specifications: a container needs some way to decide when to replicate a session to a cluster. In Orion and Weblogic this is done when session.setAttribute() is called. This works fine for things like the SessionServlet. In jsp's with the jsp:useBean ... scope=session tag, setAttribute is only called upon creation of the bean class. Modifications to the session state are done through calls on the bean class. This doesn't trigger session replication because the container doesn't know about the change. Marcel Hi, I have the (J2EE Blueprint) PetStore application clustered on two Orion instances running on the same machine. When I connect through the LoadBalancer, I can see my session state get replicated across the two nodes.

RE: java.util.ConcurrentModificationException
How are you trying to remove all of the attributes from the session, and could you not just call session.invalidate() ? This can occur if, for example, you get the attribute names out of the session in an enumeration, remove one of them from the session with a removeAttribute and then try and interate through the enumeration. It gets to the attribute that you've removed and then breaks, since it no longer exists. Cheers, Simon This email and any attachments are confidential and are intended only for the addressee.

Upgrading from 1.3.8 to 1.4.5 - (de-)serializing errors
We have encountered some serious problems when upgrading from Orion 1.3.8 to 1.4.5. The problems occurs when our business layer is about to return data to the presentation layer. The data is fetched in the datalayer via a callable statement. The callable statement and the connection is closed in the data-layer-EJB. The business-layer-EJB removes the data-layer-EJB after it has retrieved a ResultSet from it. The business-data-layer then returns data extracted from the ResultSet or sometimes just data from the ResultSet. It still works perfectly fine to use methods that submit data but not returns anything from the data layer. But after the upgrade, the methods that return data is failing.

Orion and Security (2)
Hi All, I posted an email about Orion and Security a few days ago and got some great response. Let me go into a little more details and see if what I am doing will work accordingly? 1. The security model I need is to all a user to log in once but can use multiple applications within that server. a. Server i. App1 ii. App2 iii. App3 2. Let say user1 have admin access to App1, read access to App2 and edit access to app3. a. At the initial login of the user, a security object for the user is created. There all of his/her security is loaded into the object. b. User1 go to App2, at this point, each of the App2 screen will call the security object and check to see with kind of role the user have for it. In our case, user1 only have read access which the screen will be display as read only with no edit problem. Security Summary 1. User 2. Application 3. Role(s) [Read, Modify, Delete, Add, etc] 4. Other. With the scenario I described above, I don't think it is currently available with the Orion security scheme. At each login a new security object get instantiated and populated with all the security information for the user from the database. Once the object is instantiated and populated, the database is no longer access for security. Of course this will requires some memory on the server side to hold the information but the access will be fast. This will requires an Entity Bean to do and will be managed by the container until the session is done. There are also thought of caching it for a certain period of time but probably not the first release. My question now is will the above work? Does anyone willing to share a better scheme? Any inputs will be great. Thanks Doug Pham
Re: finderException in home interface of CMP ??
I understand your point and I completely agree that it's illogical. That's why I started testing around and found out that it's not necessary to throw a finderexception in case of a return collection. Like I see it now: I finderException is never thrown in case of a collection as it always returns an empty collection when it can't find anything ? Or am I missing something here. Neither does Orion complain when you leave out the FinderException! Or are there other situations when a FinderExceptions can occur in case of a Collection ??

In your example, ttype=green_threads and not 'native'

Hi cybermaster,
In both the wrapper files If find something like below. What shall I change

I suppose the _JMS_THREADS_TYPE=native.. !

if [ ${vmtype} = classic ]; then
ttype=green_threads
LD_BIND_NOW=yes
export LD_BIND_NOW
_JVM_THREADS_TYPE=green_threads
export _JVM_THREADS_TYPE

But why ? and should I also change ttype ? If I only change the _JMS .. part
I do get the following:
[orion@ojo Orion]# java -classic -jar ./orion.jar
JVM Classic type
Could not create the Java virtual machine.

BTW: I haven't playes around with the max-instances yet, but I will do that
shorly but still don't know what the max value should be !!!

Hello everybody, How are you trying to remove all of the attributes from the session, and could you not just call session.invalidate() ? I have a class that performs database-related functions. The object of this class is saved in the session object. Now when a user logouts, I want to close the connection object present in the database class. If I called session.invalidate(), will the connection get closed? I thought it would not be possible, so I iterate through the session object and remove them one by one. When I come to the database object, I close the connection first and then remove it. If this approach is not suggested, can anybody suggest any other way? Thanks, Arun Jayaprakash. __ Do You Yahoo!?
