RE: System Date.
Title: Message make sure its not a serialisation problem - the Calendar is transient in a Date object, and it effectively holds the TimeZone, so if you have a different timezone on 2 boxes and serialise a date object between them, the milliseconds since 1970 is serialised, but the relevant time zone that it was calculatedwith is not. So when the Date is recreated, it is done with the local default time zone, but using a time in milliseconds from a different timezone, and discrepencies ensue. hope this helps, Oisín. -Original Message-From: Geoff Soutter [mailto:[EMAIL PROTECTED]]Sent: 13 February 2002 00:05To: Orion-InterestSubject: RE: System Date.

Having trouble with system Date. In Orion our application converts dates based on our users time zone. For some reason our application is producing incorrect date times. The same piece of code when ran on its own as a Java class produces correct time conversions. Are there environment variables that Orion uses that may cause it to interprets the system date differently than what the system date really is? We use a staging and production instances of Orion running on two different Unix boxes. Both boxes have the same system date, the application running on staging produces correct dates, the one on production does not, further evidence that maybe the problem lies with the Orion instance and not the code or the servers.

Re: Date conversion problem ??
I had this problem with PostgreSQL, the simplest solution is to save your timestamp as a long and construct a Date object with this long value, I've seen some sites that say the problem is a JDBC driver problem, with the PostgreSQL JDBC driver. The problem lies with the getTimeStamp() method as far as I can remember, the short of all this is: use a long value, from System.getcurrentTimeMilliseconds().. write this value to the DB, create a new Date object passing in the long value as the parameter... Hope this helps, Oisin On Monday 08 October 2001 09:04, Eddie wrote: Thanks Frederik, But what I don't understand is why Date only contains the second part and not the millisecond part and when it does ?

Eddie - Original Message - From: Fredrik Lindgren [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Friday, October 05, 2001 6:50 PM Subject: Re: Date conversion problem ?? You are right that is not the JDBC driver that makes this happen. It is JDBC itself. java.sql.Timestamp is a subclass of java.util.Date but it returns the integral seconds when calling getTime(). It supports nano second precision with the getNanos() method. The javadoc includes this note: Note: This type is a composite of a java.util.Date and a separate nanoseconds value. Only integral seconds are stored in the java.util.Date component. The fractional seconds - the nanos - are separate. The getTime method will return only integral seconds. If a time value that includes the fractional seconds is desired, you must convert nanos to milliseconds (nanos/100) and add this to the getTime value. The Timestamp.equals(Object) method never returns true when passed a value of type java.util.Date because the nanos component of a date is unknown. As a result, the Timestamp.equals(Object) method is not symmetric with respect to the java.util.Date.equals(Object) method. Also, the hashcode method uses the underlying java.util.Date implementation and therefore does not include nanos in its computation. Due to the differences between the Timestamp class and the java.util.Date class mentioned above, it is recommended that code not view Timestamp values generically as an instance of java.util.Date. The inheritance relationship between Timestamp and java.util.Date really denotes implementation inheritance, and not type inheritance.

orion-application.xml
I'm having a problem deploying to Orion, which causes the deployment time to increase over time, and eventually the jvm orion is in to run out of memory. Basically, I'm using ANT to deploy, calling the Orion admin tool (com.evermind.client.orion.OrionConsoleAdmin) and passing the relevant parameters into it. The EAR file I'm deploying includes a lib directory, with all of the required extra jar files in it (utilities, etc). In order for orion to use these when loading a bean, I put the line library path=../lib/ into orion-application.xml, between the persistence/ and principals/ tag. Orion does indeed load up the jar files as expected, so that works. The problem is that each time I deploy, the number of library path=../lib/ tags at least doubles, and at one stage I was left with over 500 library path=../lib/ tags in the orion-application.xml file. At this stage, the server slowed to a crawl, and either took several minutes to load up the beans, or else crashed. Has anybody come across this behaviour? And what can I do about it? And does anybody know of a good source of documentation on the various configuration options available for Orion, as I find it is poorly documented in all areas. Maybe the people at IronFlare could get their act together from counting all the money from Oracle, and produce a decent, (even semi-)professional set of documentation. Regds., Oisín.

There are issues with Together and jdk1.3.1 running on RH7.1. To do
this you will need to edit the java wrapper script and add the following
lines
to the top of the script:
LD_ASSUME_KERNEL=2.2.5;export LD_ASSUME_KERNEL
To edit the java wrapper on Unix, change directories into the
JDK_HOME/bin
directory and,
$ vi .java_wrapper
Also, if you are getting users with errors like:
/usr/java/jdk1.3.0_02/bin/java: /usr/bin/cut
User will need to create a symbolic link from /usr/cut to /usr/bin/cut.

Does anyone have any experience using TogetherSoft TCC v5 (or 4.x) with

I got pretty close using the EJB 2.0 generic version in TogetherSoft but

Re: Simple Clustering Question
Hello All, I just thought I'd send this to explain to people who are having trouble understanding how to set up the default web app clustering and exactly how a broadcast IP is set up. I am a newbie to Orion Server and got 4 machines to act as a cluster after some advice from Lachezar! I'd like to thank Lachezar and Juan and for their help on the Orion interest mailing list. Before You Start The Servers. You need to have a broadcast network address for all the machines on your cluster, this could mean having to have an extra network card configured for that broadcast IP address or configuring you network card to listen to a broadcast ip address in addition to the hosts ip. The default broadcast ip for Orion is 230.0.0.1, so you'll need to change the setting in orion/application-deployments/default/defaultWebApp/orion-web.xml if you want to use a different broadcast ip address and port number. Then you can follow the document: Enabling Web-Clustering in Orion Oisin Enabling Web-Clustering in Orion Setting up the server 1. Install orion and start it. 2. Edit the orion/application-deployments/default/defaultWebApp/orion-web.xml file and add: cluster-config / 3. Repeat 1 and 2 for another (or more) box(es).To test: 1. Go to http://box1/servlet/SessionServlet. Reload a few times. 2. Go to http://box2/servlet/SessionServlet;jsessionid=ID YOU GET ON YOUR BOX1 SCREEN. The counter should be the same as for the other box (box1).To put this into production: On Sunday 10 June 2001 12:08, you wrote: Hi. you need a switch which has multicast enabled; (most ethernet switchs have this capability, some just don't have it enabled) That is not true. Multicast is a network service. It is of type send-on-receive-anyone. That means, that one packet is send and it is received by anyone, listening to that multicast IP/PORT. If you have an Ethernet, than you have the Multicast ability. Routing multicast packets is a different question. Having one, or more Ethernet networks, connected with dumb equipment (HUBs, SWITHCHes, REPEATERs) also gives the multicast routing. Internet multicast routings is somehow more complicated. It is enough to say, that if you have a single dumb ethernet connection between your boxes is enough for the Orion multicast clustering to work. Of course all the boxes have to be configured to use one and the same Multicast IP and one and the same PORT. That's it. Lachezar. Hi, I've spent the last while trying to get clustering to work with orion server 1.5.2 without success. First I tried to follow the instructions at http-clustering-howto.html from the documentation, it said: Setting up the server 1. Install orion and start it. 2. Edit the orion/application-deployments/default/defaultWebApp/orion-web.xml file and add: cluster-config / 3. Repeat 1 and 2 for another (or more) box(es). But when I tried to connect to the server, the server let me know that the file /orion/default-web-app/WEB-INF/web.xml hadn't got the tag distributable/ in it. I then added this tag to all servers /orion/default-web-app/WEB-INF/web.xml file in the cluster, and tried again, this time they actually ran the SessionServlet but as if they were being run individually, i.e. the session wasn't shared as it was supposed to be, I did remember to append ;jsessionid=ID YOU GET ON YOUR BOX1 SCREEN to it and tried both leaving the angle brackets in and out. I know I must be doing some thing wrong but I can't find it, I'd really appreciate some help. I noticed in the http-clustering.html that in the clustering it mentions the default for multicast host/ip to transmit and receive cluster data on is 230.0.0.1, port number 9127, does this mean I have to have a network card listening on this IP/port? What exactly is a network with operational multicast facilities, is plain 100Mbs ethernet running on linux OK?
