RE: timed events
I have done this using the java.util.Timer class. I created a class that extends the TimerTask class, and calls the EJB. I made a singleton class that wraps the Timer class, so I can call it from the servlet layer to schedule tasks, and guarantee only one instance per VM. Thus, my EJBs aren't forking threads, so it should be OK. And the Timer instance, which controls the scheduling of the tasks, is always alive as long as my VM doesn't go down. I saved the schedule times and taskIds to the database so that they can be rescheduled when the appserver gets restarted. I created an application that reloads these jobs, and put this in client-module of orion-application.xml, so Orion would start it on startup. This works, and I haven't had any problems yet, but I'm not sure whether this is the best, or most valid approach. It feels a bit too easy to be any good. Alternatively, you can use a 3rd party job scheduler. This is free, and it has one: http://ofbiz.sourceforge.net/ http://ofbiz.sourceforge.net/core/docs/services.html I haven't had a chance to evaluate it. -Original Message- From: Johan Fredriksson [mailto:[EMAIL PROTECTED]] Sent: 13 March 2002 13:06 To: Orion-Interest Subject: Re: timed events Perhaps via a croned java client? //Johan - Original Message - From: Casper Højstrup [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Wednesday, March 13, 2002 10:20 AM Subject: timed events This more of a regular EJB question, I suppose.

OS is Windows 2000 and WinNT for server, and Win2000 only for clients. Win2000 is SP2. The plot has thickened as well, The problem only happens sporadically. I can no longer reproduce the problem on these versions, they are now uploading fine!! Nothing has changed, other than we have upgraded IE to version 6 on other machines on the network. When it has happened, I have examined the InputStream that is sent to the server, and when it fails, it appears the HTTP header is being sent as content as well as a header, so the MultiPart parser does not see a valid content boundary.

For example, the original release of 5.5 was very buggy, but it's had at least a couple of Service Packs since then (5.5.1, 5.5.2, if you like). You need to indicate which service pack and which OS you are running on before you can really compare IE versions properly. You may also wish to ensure there are no proxies or anything like that in the middle between IE and Orion, as they can change the HTTP stream. Also, have you configured IE to use HTTP 1.0 or 1.1? Try running the same example code on Tomcat 4.x, with your different browsers. If that works you can pretty much blame Orion.

Uploading files to Orion webserver with MultipartParser API
Hi, I'm wondering if this has anything to do with the Orion webserver. I am using the com.oreilly.servlet.multipart.MultipartParser to upload files to my servlet. If you try the same file several times, it will sometimes work and sometimes fail with a Corrupt form data: no leading boundary IOException. It fails because normally it expects to see a valid boundary in the HttpServletRequest obj, but some of the time the Header is being sent with the content. So where it expects to see something like 12012133613061, it finds a POST url... HTTP1.1 etc It is strange that it sometimes works and sometimes not. Is there anything I can set on the webserver side to ensure that the content is as is expected? Thanks, Justin

What I've done so far is this: 1. Implemented a java.util.Timer as a Singleton which is accessed from the servlet layer. 2. Implemented a class that extends TimerTask, which does a JNDI lookup of my EJB and invokes the appropriate method. 3. Call the Singleton from the servlet to schedule the TimerTasks as per client requests. (Plus save details to database) 4. Implemented another app to be called via the client-module tag which reschedules the previously scheduled TimerTasks. Thus I have my persistence. 5. The Singleton runs the ReScheduler whenever its recreated. 6. Run orion using the -userThreads parameter - this is necessary. So, as long as my Singleton class stays up, I should be OK. The problem is, some tasks might be scheduled for weeks or months away. How can I guarantee that it will fire at the scheduled time even if it is this long away? I understand that there may be several instances of the Singleton per classloader, thats OK, as long as its a finite amount. So. My question now is: Is this as robust as it gets?

One thing I have noticed is that Orion runs slower this way than if you start it from a command prompt. Anyone know anything about this? I've asked this before.

Dear all, I'm trying to find a way to start Orion Server as a service in WindowsNT/2000( i.e.Orion will be started automatically when my computer startup without any user interaction). Any one know how to do this ? I tried this as below but it failed : 1. Write an small Win32 application "startorion.exe" that calls "java -jar orion.jar" 2. Register it as a automatic service (named MyService) with Win2000 using "Service Installation Wizard" tool in the Windows 2000 Server Resource Kit. 3. Restart my computer. Then I can find item "MyService" inthe list of all available services in my computer. But this service can not be start. Any idea ??? Thanks in advance. Vu Le Hung
RE: Transaction behaviour
Title: RE: Transaction behaviour Hi Ampie, Thats my problem, merely catching the CreateExceptions, etc and rethrowing as EJBExceptions apears not to be sufficient to guarantee a rollback, I must call setRollbackOnly() prior to rethrowing. Is this for definite? I would have expected that explicitly throwing EJBException would automatically cause a rollback because it is considered to be a system-level exception. Does the container analyse the nested Exception to determine if it is sourced as a system exception and not rollback EJBExceptions thrown from application-level Exceptions? I'm sure my confusion is apparent now ;) Thanks, Justin -Original Message-From: Ampie Barnard [mailto:[EMAIL PROTECTED]]Sent: 22 October 2001 07:00To: Orion-InterestSubject: RE: Transaction behaviour Orion's implementation is quite correct in returning a method result and not throwing any exceptions, in spite of your invocation of setRollbackOnly. Personally, I only call setRollBackOnly before (re-)throwing an application exception that should definitely cause a rollback. Rolling back the transaction without throwing any exceptions will just confuse the users of my ejb's. It is probably better to just wrap such an application exception in an EJBException and let the container roll the tx back. Remember that CreateException, RemoveException and FinderException are considered to be application exceptions. If you propagate these exceptions but still want to roll the tx back, you have to catch them, call setRollbackOnly() and then rethrow them. Subclasses of Error, RuntimeException (EJBException) and RemoteException are considered to be system exceptions and will automatically cause a tx rollback. -Original Message- From: Justin Crosbie [mailto:[EMAIL PROTECTED]] Sent: 19 October 2001 05:34 To: Orion-Interest Subject: Transaction behaviour Hi all, We have implemented a session facade architecture, with session beans calling multiple entity beans.

The stateless bean always tries to create the entity beans. We would like it such that if either fails to create, the method does a rollback - all or nothing. Does this mean that we must call setRollbackOnly() ? Thanks for any help on this. Justin
RE: JavaMail problem
Hi, Thanks for the replies. Still no joy, this is strange behaviour. We don't want to enable relaying totally, because of the security risks. Yet its still a problem if we enable it for specific IP addresses, it doesn't work. We can enable routing to specific external domains, and this works. Anyway, it appears to be either a JavaMail or Exchange Server problem, so I'll keep looking there.

RE: MDB in orion 1.5.2 using Queue
Hi Romen, did you specify the admin security credentials? its -Djava.naming.security.credentials=admin password If you don't give this, it pops up a textbox asking for the password. Maybe you are tabbing off this before it pops up? Did you enable jms from server.xml by uncommenting the jms-config node? I did not have to do anything to orion-ejb-jar.xml. I configured my ejb-jar.xml as follows: ejb-jar descriptionMessage Driven Bean/description enterprise-beans message-driven ejb-nameMyMDB/ejb-name ejb-classpackage.MyMDB/ejb-class transaction-typeContainer/transaction-type acknowledge-modeauto-acknowledge/acknowledge-mode message-driven-destination destination-typejavax.jms.Queue/destination-type subscription-durabilitydurable/subscription-durability /message-driven-destination resource-ref res-ref-namejms/QueueConnectionFactory/res-ref-name res-typejavax.jms.QueueConnectionFactory/res-type res-authContainer/res-auth /resource-ref resource-env-ref resource-env-ref-namejms/theQueue/resource-env-ref-name resource-env-ref-typejavax.jms.Queue/resource-env-ref-type /resource-env-ref /message-driven Hope that helps, Justin -Original Message- From: Romen Law [mailto:[EMAIL PROTECTED]] Sent: 18 October 2001 01:05 To: Orion-Interest Subject: MDB in orion 1.5.2 using Queue ello, I tested MDB using topic and it worked fine.

JavaMail problem
Hi all, I'm having trouble enabling relaying on my mailserver. I'm using Orion 1.5.2 with the J2EE 1.2.1 JavaMail, trying to relay toa 5.5 Exchange Server(NT).I've set the application.xml to point to my Exchange server as such: mail-session location="mail/TheMailSession" smtp-host="my.mailserver.ie" property name="mail.transport.protocol" value="smtp"/ property name="mail.smtp.from" value="user@company.com"/ property name="mail.from" value="user@company.com"/ /mail-session I have set Exchange to disable relaying except for the IP address of the machine the appserver is on. The problem is I'm still getting the "javax.mail.SendFailedException: 550 Relaying is prohibited" error. Can anyone shed any light on this? Is there something in Orion I need to do as well? Thanks for any help. Justin Crosbie
