Re: Where are the perfumes bubble bath beads
Hmmm, as for WebsPhear ( really liked that one:) ) and IBM support they don't give you support if you're not $1.000.000.000 company. Well, sometimes they do but only if you get ugly with them on phones and harass them enough. They don't care about small businesses... At least that is the case in Sweden. Don't know about the rest of the world, but it's probably similar. And unconfirmed sources say there is only 1 (one) expert at WebsPhere in Europe, and he works at a lab in France.

I can't say enough about being able to run our entire application on a single Win98 box! It means that we can setup a demo on a portable PC, and have a marketing person show up at a meeting and run a full demo from that portable. We do not need an internet connection, nor a $10,000 machine. Also, this means that developers can take work home with them, and not worry about their connection to the office. It also means that developers can work complete independent of each other, without stepping on eachother with every little change to the deployment. If Orion were used only for development and demos, and your application was then deployed on a different app server, I think it is worth the $1500! tim.
RE: Using Log4j With Orion
Hi,
cat.debug("message")and friends works on most appservers. What the
spesification says is that you can't open a file input/outputstream directly
from an ejb and this is because of portability. So output to screen should
always be possible from an ejb.
And this is what log4j does its realy just a System.out whit dynamic filters
on it.

I'm unable to find this thread in the archives. Does anyone have any link to it? I don't, not offhand, but I can see the logic. However, there's no need for J2EE, if applets are dying; they're a neato gadget whose time has largely come and gone, IMHO. Great for *very* vertical applications, lousy for everything else. (And yes, online games are "vertical apps," because the users are generally willing to do what's necessary to get them to run.) Also, is there anyone who is currently using, or has previously successfully used, applets in a production orion application? I would appreciate knowing your experiences. I've used them; the #java faq (http://epesh.com/java) has references to at least one applet in it; orion has no bearing on applets in the general case. The exception, of course, is the applet that uses JNDI to locate things: don't do this. An applet like that is wayyy too heavy. --- Joseph B.

Greetings, We are currently evaluating the various J2EE solutions available for a venture that we hope to deliver to the world in a few months. Whilst reading the documentation for each, I dont appear to be able to configure Orion to suit the way the project will work. In order for our application to be of any use, we need to be able to implement a fair amount of security, since JSP pages may be at the mercy of people who are not us. Basically the application will provide a farm of hosts on which we will be offering certain services. Each application needs to have a data source that it, and only it has access to. The current problem as I see it is that if I define a connection in data-sources.xml, then every web application deployed on the server or cluster of servers has access to it. We need some way of securing that while still being able to use EJB in all its glory. We need to be able to offer the opportunity of creating and editing content without compromising the security of other applications on the system. Could anyone give us some tips and pointers on this?

Re: Does OrionServer 1.3.8 work on SCO Unixware?
Hi Ismael, Orion *should* run on any operating system, as long as a working Java 2 implementation is available (J2SE 1.2 or later). Could you try setting JAVA_COMPILER=NONE, make sure that java -version indicates that no JIT is used and then report the exact trace again? Turning off the JIT *may* even solve the problem, but if it won't, then at least it will show more information w.r.t. line numbers. The version number of your JDK indicates you're working with a custom-compiled version of the JDK for your platform. Did you compile it yourself ?

Sears and Orion - a hardware question
In following the discussions from the person working with Iplanet, I understand that you could have a hardware solution with multiple Orion servers. Did I understand that correctly? Let me pose a hypothetical question: Suppose a company the size of Sears, picked Orion and Gemstone as the solutions to run their e-business, and the site would have a magnitude of traffic. The Gemstone respondent mentioned that VM's max out at 100-200 concurrent users, and that Gemstone would start or use another VM. Could a solution be found with hardware and Orion, that would equal the Gemstone solution, should money be no object? If so, then what would it be and how would you configure it (high level)? Out of curiosity, what would be the more cost effective solution?

Mixing secure non-secure pages in the same application

For a VERY temporary fix, I turned on IIS on the same box, and do a redirect from IIS:80 to Orion:443.

JMS client sender to queue fails
Hi. I was trying orion (1.4.7) with some code samples taken from Sun's
J2EE1.3 JMS tutorial.
one of the simplest is a client that sends a message to a queue :
snip
jndiContext = new InitialContext();
queueConnectionFactory =
(QueueConnectionFactory)jndiContext.lookup(INames.QUEUE_CONNECTION_FACTORY);
queue = (Queue) jndiContext.lookup(INames.AREGON_TEST_QUEUE_1);
queueConnection = queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false,
Session.AUTO_ACKNOWLEDGE);
queueSender = queueSession.createSender(queue);
TextMessage _message = null;
String _msgText = "Here is a message ";
_message = queueSession.createTextMessage();
for (int i = 0; i 5; i++)
{
_message.setText(_msgText + (i + 1));
System.out.println("Sending message: " + _message.getText());
queueSender.send(_message);
}
/snip
I managed to set up everything correctly (server.xml, jms.xml,
application-client.xml) I think, but at the
queueSender.send(_message);
line, an exception is thrown :
javax.jms.JMSException: QueueConnection not started

RE: Any news from Orion yet??
Thank you for pointing me out to the site again, and I do love that site. The article on Uncle Gates not liking open source is interesting. It could be due to a government decision in September to allow government sites to bid on open source (I think the announcement is www.mysql.com, under NASA headlines). I find just the opposite position was taken when someone from Gates company complemented the Perl and Python usage for their net products (www.activestate.com, a while back). Does that mean Uncle Bill embraces open source, when it is to the advantage of Microsoft, but fronds on it when it affects the bottom line?

They come with nice tools like front end gui's, good documentation, paid support, etc. But if you look for the opinions of developers who have used these products, and compared them to Orion, jboss, etc., they would say the EJB capacies are no better then the other high priced products. In order of ranking, here's how I look at the other products. 1 Orion -- This product is ready now, but I haven't seen anyone from this list run a Sears store on it. 2. Jboss (www.jboss.org) -- The founders are very bright, have five hundred developers on the projects, have EJB heavies contributing to the list, and it's a very easy to use product. Personally, even though it is ready for production now, I would wait for it to mature a bit more. It's like a fine wine -- drink it now, and it is OK, or allow it to age a bit then drink it (like jboss 3.0 final). 3. Openejb (www.openejb.org) - this project has a very bright and well known person heading it, and it is slated to be intergrated with Tomcat and Apache. It has yet to prove itself, as it is not yet ready for production release. But it has good future promise. 4. Jonas (www.evidian.com/jonas) - This is a good product, but it is not as advanced as the other two open source products and I don't think they have as many people behind them. 5. Enhydra enterprise (www.enhydra.org). If you like the enhydra application server, this product has potential. But it is not production ready yet and it intergrates with the jonas server. In summary, Orion is here now but can it run Sears? Jboss is ready but I would let it mature a bit more for production environments. Openejb and Enhydra have great potential, but they are not ready yet and have to prove themselves. Jonas is OK but I prefer the other open source alternatives. -Original Message- From: Anthony W.

Re: Is there anyone there ?
Then you are most likely (very likely) subscribed with a second address. What that address is you have much better chance of knowing than we do, it is *impossible* for us to unsubscribe people who dont even know themselves which address they're subscribed with, so it is important when you join a list that you remember the exact address you subscribed with. And even if it was possible we would not spend resources on that kind of activity - this list is a 'self serving' list and it's important to remember that. Some common mistakes: subscribing with [EMAIL PROTECTED] and then attempting to unsubscribe [EMAIL PROTECTED] subscribing with [EMAIL PROTECTED] and then attempting to unsubscribe [EMAIL PROTECTED] or vice versa. subscribing with [EMAIL PROTECTED] and then attempting to unsubscribe [EMAIL PROTECTED] or any combination of the above (there are other variants as well). The simplest way to unsubscribe is to go to http://www.orionserver.com - mailinglist and enter the *address you used when you subscribed* (casing does not matter however) and click unsubscribe. There is a quirk however; the message you receive will be erronous (saying that you have subscribed) but dont worry, the action taken is still correct (we'll try to fix this in the near future to avoid confusion). Of course there could be a bug in the listserver causing your phenomena, it's just unlikely (and we dont know of any such occurances so far) and it's a lot more common for users to have subscribed with multiple addresses that they forgot about. Side note; there's been a lot of inquiries regarding a digest version of the list; the answer is that it's not possible right now. The best option is probably to unsubscribe if you have problems with the quantity of mails and instead follow it via the archives (external service, but linked at http://www.orionserver.com/ - mailinglist). Another thing is for posters to go through the usual "does this benefit the subscribers of the list?" sanity check. For instance general J2EE technology (including servlets/JSP, EJB etc) questions are often better off at the 'neutral' ***-interest lists hosts by Sun, as is general server comparisons/questions etc. Meanwhile Orion-Interest is geared towards technical issues related to Orion usage (and to view it from the other perspective: those questions should not pollute the 'neutral' interest forums since they belong here and not there). Lastly; be sure to appreciate people who respond to your/others queries, and not to be annoyed if your particular query - they're taking time helping you simply out of friendliness, and that should be appreciated.

Is xerces.jar too old ?
Our application uses XML data exchange wrapped into HTTP. It is handled by a servlet running under Orion and doing its own XML parsing and generating. We are using pretty convenient XML API (Jdom ) from http://www.jdom.org which I highly recommend. The jdom.jar bundle comes with the latest (?) xerces.jar which I also copied into /Orion/lib directory. My standalone code worked fine, but after I placed it into servlet it did throw NoSuchMethodException complaining at some xerces code. Apparently Orion's classloader uses xerces.jar from the Orion root directory prior to the one placed in Orion/lib directory. Everything works fine after I replaced the old xerces.jar in the Orion root directory with the new one which came with jdom.jar bundle. I don't like that hack because it's an alteration to Orion distribution and hell knows what side effects it may cause. So, my question are : Is there any way to force servlet in using certain library if there is some naming conflict with the one in Orion root ? Orion team, are you going to update xerces.jar in distribution ? Does it involve any licensing issue ? Thanks ~boris

I am positive that the ejbCreate methods of A and B could include an instantiation like "foos = new Vector();" but if I use this model, I have to remember to write this instantiation into every subclass of S, and if S has many member variables (and many subclasses) that becomes error prone. - Not to mention that if I add a new member variable to S I have to modify all subclasses A, B, etc. to make their ejbCreate(...) instantiate this new variable. My own suggestion is to define a method in S, lets call it "void instantiateS()" and have subclasses A, B, etc. invoke this method in their ejbCreate(...). I believe this method should *not* be the (no-arg) constructor of S as I expect this contructor will be called everytime an instance of A or B is loaded from persistant storage (which is unnecessary).

Servlet Method size limit? -- Illegal target of jump or branch

If I start eliminating some of the tags (doesn't matter which ones) the problem goes away. I've tried increasing my JVM heap. No luck. Where is this limitation coming from? My JVM? Orion? The only way to get around it that works is by writing taglibs to eliminate the amount of code in the JSP. Any other suggestions?
RE: Best practices: How to initialize state in EntityBean's superclass
I am doing something very similar to what you described. My base class is
actually coded like a Entity bean so that it has all the ejbActivate,
ejbLoad, ejbStore etc. Hence it is a self-contained entity bean which
handles its own state information nicely and my subclasses are not required
to re-declare those dummy functions if they do not need to.
Something like the following: -
abstract class MyBase implements EntityBean {
protected transient EntityContext ctx;
Vector states;
/** My pseudo ejbCreate function */
public void ejbCreate() {
states = new Vector();
}
public void setEntityContext(EntityContext ctx) { this.ctx = ctx; }
public void unsetEntityContext() { this.ctx = null; }
public void ejbActivate() {
states = new Vector();
}
public void ejbPassivate() {
states = null;
}
public void ejbRemove() {
stats = null;
}
public void ejbLoad() { }
public void ejbStore() { }
}
public class MySubclass extends MyBase implements EntityBean {
String value;
public Integer ejbCreate(String value) {
super.ejbCreate();
this.value = value;
return null;
}

(only for static web site though).

In ${orion_home}/default-web-app make an index.html that redirect to
port 443 that should do it.

How do you serve both secure and non-secure pages from the same
application
Right now, my entire application is secure and served from port 443.
If someone types in the URL, the server does not respond because I am
not running anything on port 80. For a VERY temporary fix, I turned
on IIS on the same box, and do a redirect from IIS:80 to Orion:443.
My goal is to have one application, serve the splash screen in
non-secure mode, and serve the rest of the screens in secure mode.
I searched the documentation / mailing list, but did not find
anything.
Thanks,

RE: Best practices: How to initialize state in EntityBean's superclass
Why not just put the superclass initialization in ejbCreate() and require all the subclasses to call super.ejbCreate()? Jeff -Original Message- From: Randahl Fink Isaksen [mailto:[EMAIL PROTECTED]] Sent: Monday, February 19, 2001 4:18 PM To: Orion-Interest Subject: Best practices: How to initialize state in EntityBean's superclass Suppose you have two EntityBean classes A and B which share some common functionality and state by inheriting from the same superclass S. Then, if S has some member variable, say a java.util.Vector called "foos", which is part of the persistent state of both A and B, my question is this: When should "foos" be initialized? I am positive that the ejbCreate methods of A and B could include an instantiation like "foos = new Vector();" but if I use this model, I have to remember to write this instantiation into every subclass of S, and if S has many member variables (and many subclasses) that becomes error prone. - Not to mention that if I add a new member variable to S I have to modify all subclasses A, B, etc. to make their ejbCreate(...) instantiate this new variable. My own suggestion is to define a method in S, lets call it "void instantiateS()" and have subclasses A, B, etc. invoke this method in their ejbCreate(...). I believe this method should *not* be the (no-arg) constructor of S as I expect this contructor will be called everytime an instance of A or B is loaded from persistant storage (which is unnecessary). What are your suggestions? What do you do when using inheritance in your beans? Any comments would be appreciated. Randahl.

Re: Servlet Method size limit? -- Illegal target of jump or branch
This has been discussed before, so there are postings in the archive. The problem lies in the Class files themselves. Java Class files have 16 bits limitations, as well as others. The primary issue appears to be the large number of string constants generated by JSP pages. I believe that workarounds were suggested in the previous postings. tim. I get the following error using Orion 1.4.7 w/ JDK 1.3 on Redhat. Error creating jsp-page instance: java.lang.VerifyError: (class: __jspPage11_register_regstep2_jsp, method: _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletRespo nse;)V) Illegal target of jump or branch It is due to a large JSP file (mainly due to a lot of tags, not a lot of logic). If I start eliminating some of the tags (doesn't matter which ones) the problem goes away. I've tried increasing my JVM heap. No luck. Where is this limitation coming from? My JVM? Orion? The only way to get around it that works is by writing taglibs to eliminate the amount of code in the JSP. Any other suggestions?

RE: Is xerces.jar too old ?
Hi, We just had the same problems. The $ORION_HOME/xerces.jar version is old and could not handle our need in XML parsing. We have replaced this file by a new version and all is fine! We use Orion 1.4.4, old xerces.jar was 589 KO, and new one is 769 KO (don't know how to check version...). I know this is not a good solution, but Orion seems to give his own CLASSPATH to the application he ran, so even if you had the new xerces.jar in the CLASSPATH specified with LIB tag it'll be hidden by the Orion's one. If some have idears on this subject... PHiL -Message d'origine- De : Boris Erukhimov [mailto:[EMAIL PROTECTED]] Envoy : lundi 19 fvrier 2001 17:50 : Orion-Interest Objet : Is xerces.jar too old ? Our application uses XML data exchange wrapped into HTTP. It is handled by a servlet running under Orion and doing its own XML parsing and generating. We are using pretty convenient XML API (Jdom ) from http://www.jdom.org which I highly recommend. The jdom.jar bundle comes with the latest (?) xerces.jar which I also copied into /Orion/lib directory. My standalone code worked fine, but after I placed it into servlet it did throw NoSuchMethodException complaining at some xerces code. Apparently Orion's classloader uses xerces.jar from the Orion root directory prior to the one placed in Orion/lib directory. Everything works fine after I replaced the old xerces.jar in the Orion root directory with the new one which came with jdom.jar bundle. I don't like that hack because it's an alteration to Orion distribution and hell knows what side effects it may cause. So, my question are : Is there any way to force servlet in using certain library if there is some naming conflict with the one in Orion root ? Orion team, are you going to update xerces.jar in distribution ? Does it involve any licensing issue ? Thanks ~boris
Problems deploying a MessageDrivenBean
Hi, I am currently trying to deploy a very simple Message Driven Bean (MDB) in Orion 1.4.5. The MDB is subscribing to a topic. To do this I have studied the atm application and the logging MDB used there. Orion deploy's my MDB without any error messages but the bean is not responding when a message is published on the topic. To me it seems like the MDB doesn't know or understand what topic it should subscribe to. I use a client to publish a message on the topic. If I start another client subscribing to the same topic, everything works fine. The jms.xml file seems to be ok. I think I am missing something connecting the MBD with the topic in the ejb-jar.xml file. When I created my ejb-jar.xml file I copied the relevant parts from the atm ejb-jar.xml file. I have studied other MDB examples and tried to modify my ejb-jar.xml file according to those examples but so far nothing has worked. My MDB is the src.java.ejb.NewOrderBean and the topic name is orderTopic. This is my ejb-jar.xml file: ejb-jar enterprise-beans message-driven ejb-namesrc.java.ejb.NewOrderBean/ejb-name ejb-classsrc.java.ejb.NewOrderBean/ejb-class message-selectorJMSType='orderTopic'/message-selector message-driven-destination destination-typejavax.jms.Topic/destination-type /message-driven-destination /message-driven /enterprise-beans /ejb-jar My hopes are that someone could help in this matter.
