Re: how to set exclusive-write-access=true in orion-ejb-jar.xml
I think orion finds out your database doest suport this feature or its not yet implemented for this db in orion. Exclusive-write-access default is set to true, so i beleive that orion resets it cause its not available.Otherwise be sure you remove orion-ejb-jar.xml before you deploy and make sure the one you deploy in your ejb.jar META-INF is valid . At deployment you should see a message about orion copying the orion-ejb-jar.

Re: JNDI question: client talking to EJBs on multiple app servers
Brilliant -- thanks. What I couldn't find was any documentation
on what goes in the environment Hashtable. :)
What does the dedicated.connection=true property do? If I were
to do this:
public FooRemote getRemote(String jndiURL)
{
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, jndiURL);
InitialContext context = new InitialContext(env);
Object ref = context.lookup(EJB_NAME);
FooHome home =
(FooHome)PortableRemoteObject.narrow(ref, FooHome.class);
FooRemote remote = home.create();
return fooRemote;
}
public void doStuff()
{
FooRemote beanOne = getRemote(ormi://fred/app);
FooRemote beanTwo = getRemote(ormi://wilma/app);
// do stuff...
}
Will it work? Or is the remote going to get confused as to
which server it points to?

Hi.
A working model is to create two Initial Context-s for each server.
Use a dedicated.connection=true property to create the context.
The dedicated.connection however leads to resource leakage, and if you
keep creating more and more of them you will eventualy get
java.lang.OutOfMemoryError: Can not create native thread at some 200-300

If you create an context for both servers, and then use them later you
might not have this problem.
public static Context[] connections;
public void ejbCreate(){
if ( connections != null ) return;
Hashtable env = new Hashtable();
// Use any of these.

ClassCastExceptions in EJB client: What am I missing?
So I have a session bean, Home interface, Remote interface, Bean class, the works. When I invoke it from a web application within Orion, it works fine. When I try to invoke it from a standalone client, I can look up the home interface but I can't narrow it. I get: java.lang.ClassCastException at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296) at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137) ...[etc.] Now, it's pretty clear to me that I'm missing something on the client side, because if after Object ref = jndiContext.lookup(ejb/Foo); I add System.out.println(ref.getClass().getName()); on the web-app side, the working side, I get FooHome_StatelessSessionHomeWrapper37 but on the standalone client side I only get __Proxy0 whatever that is. Do I need to be generating the client-side stub classes somehow and including them with the standalone client? How do I do that? I find references in the Orion documentation to something called an EJB client JAR but nothing on how to create one or what's supposed to go in it. I've seen two or three questions on this sort of ClassCastException in the archive for this mailing list but haven't been able to find answers to any of them. Has anyone got an answer?
Java newsgroups: Entity Beans not synchronising with database
We are currently using a stateless session bean to perform a direct update of a table in the database and then usinga findermethodin the home interface of an entity bean which is mapped over the same table to retrieve the records that have just been updated. Because both transactions are managed by the application server, it should know that theentitybeansneed to refresh from the database because some data has changed. However the result is that the direct update is committing the change to the database as you would expect, but theentity beans retrieveddo not reflect that change.Do we need to force theentity beanto refresh from the database?

Apache/SSL or Stronghold as Orion Frontend
Is it possible to successfully have Stronghold (ssl) proxy requests to a non-ssl Orion on the backend? I can proxy all day long http -- http, but it seems that Orion has no mechanism in the frontend portion to say the protocol is https, not http when you need to do a redirect. If I say port=443 it tries to use http on port 443. This is bad and breaks things. The Stronghold side is trivial with mod_rewrite or mod_proxy, it's just that Orion is failing to use the right protocol when doing redirects, be them internal (to make /foo turn into /foo/) or be it within a Java program. ASCII for those who like visuals: [https://ssl.server/foo] --(rewrite)-- [http://private.orion/foo] Is this possible without setting Orion up with ssl support? Help. -- David S.

-Original Message- From: David Potts Sent: 11 October 2001 10:02 To: 'Orion-Interest' Subject: RE: How to get the RoleManager inline -Original Message- From: Mike Cannon-Brookes [mailto:[EMAIL PROTECTED]] That won't help - I think shared sessions only work between two WARs in the same app. We could probably live with merging the two apps into WARs in the same EAR file. However, we've just tried that with a test app and with the shared flag set to be true in both of the web-app tags in default-web-site.xml (and also in default-web-app for good measure!) and we have the same problem: the second app again goes to the login form. Any ideas of what config we might have go wrong? Juan Lorandi in this thread mentioned putting shared=true in orion-web.xml but we can't find that in the docs. What tag attribute do we apply this to? Juan also mentions the same realm name, but this is just for BASIC authentication I believe, and we unfortunately have to use FORM based authentication. Is that right? The only thing I can suggest is using some sort of cookie based system where you track via session ID who is logged in (stored in a hashmap or something), then from each app lookup that hashmap (via JNDI) and log in the user programmatically before they are shown the login page. Very fugly though. SSO is one of J2EE's problems. So the flow of that solution would look like: (1) User logs into app1 (2) Store user info in JNDI somewhere that app2 can see it (3) The user clicks a link that would take them into app2 (4) Intercept the login-request and use the stored info to log the user into app2 The problem with this flow is that we don't know how to intercept at step (4) *before* the user is shown the login form by the container. Is this possible? If not, our idea similar to this would be: (1) User logs into app1 (2) Convince the app2 security (RoleManager?) that the user is logged in using the values passed to app1 (3) The user clicks a link that would take them into app2 and is already logged in Hence the original question in this thread: how from app1 do we get hold of app2's RoleManager? Thanks for all the help. Dave.
RE: How to get the RoleManager
-Original Message- From: Mike Cannon-Brookes [mailto:[EMAIL PROTECTED]] I have a feeling if you made app2 the parent app of app1 it might work (they'd probably be the same RoleManager - can't confirm that though). Thanks for the suggestion. We tried it, but it doesn't work. When we go to the second app the login form comes up again. This is a non-standard solution (if a solution at all! ;)), then again if you're using RoleManager you're already using Orion specific code so you probably don't mind too much. At the moment we are looking for *any* solution that will do form-based single signon across two apps on Orion. What is the standard? Cheers, Dave.

MAPPING MORE THAN ONE WEB RESOURCE TO SECURITY ROLES
I have protected my Application with declarative security and all works properly. When somebody try to access the Main Page, the Basic Authentification turn on. That´s good. I have also protected methods and mapped it with roles. Now... I want to protect a second web recourse, a .js (script src="javascript:void(0);"/script) file but only for a few security-roles. If the role is allowed, the script is charged, if not, the script is not charged. The problem is that when I try to access this Web resource, Orion asks for my login and password again - as if the verification hadn't been stored in the session. If I try to enter with a rol that isn't mapped to this resource, it doesn't even recognize the user and the password. How can I make it so that Orion only asks me ONCE for my username and password and also so that I can load Web resources without having to enter my password, etc... again (assuming I have the correct permissions to load the resources in question).

STRANGE (and BIG!!!) PROBLEM
It's a little bit strange... I'm implementing security on my application and customizing my xml descriptors. All went ok (I had Basic Authentication) and I wanted to implement security also in the EJBs methods. I change the ejb-jar.xml source and this text appears : Auto-deploying UbicuaCMP.jar (Classes were updated)... The compiler has run outof memory. Consider using the "-J-mxnumber" command line option to increase the maximum heap size.Error compiling D:\Orion155\ubicua/UbicuaCMP.jar: Syntax error in sourceOrion/1.5.2 initialized I work with 512MB memory... so I don´t think is a problem of lack of memory... I try to use also the "-J-mxnumber" command but it doesnt work !. Can anybody explain where and how works this command ? (a sample example will be wellcomed !)

RE: Which JAR do I need to run an external client app
Peter, In getting my app-client running, I down loaded http://java.sun.com/dtd/application-client_1_3.dtd and found this statement: The ejb-ref-name element contains the name of an EJB reference. The EJB reference is an entry in the application client's environment and is relative to the java:comp/env context. The name must be unique within the application client. As you can see, ejb-ref cannot be used in your case since you do not want your client in every ejb container. Also res-ref has the same problem. It looks like your client needs to use rmi to call the ejbs. Look at rmi.xm.html in Orion's docs. Set up the server, using rmi.xml, that contain the ejbs your client-app needs to use. Then set up you client to connect to the appropriate server:port for the needed ejb using rmi. Hope this helps.

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.

RE: Calling EJB From a Servlet..
Prashant, You cannot initialize the context within the servlet. Use web.xml with the following entries with your values: context-param !-- The context-param element contains the declaration of a web application's servlet context initialization parameters. There are two special kinds of initialization parameters for the optional cases where the parameter is used to obtain the JNDI name of an EJB or a data source for a subsequent look up. These are indicated by an context-param element together with an accompanying ejb-ref or resource-ref element with matching name. -- param-nametheName/param-name !-- The name of the configuration parameter. -- param-valuetheValue/param-value !-- The value of the configuration parameter. -- /context-param resource-ref !-- The optional resource-ref element contains a declaration of a Web Application's reference to an external resource.

The context-param's value may be specified at deployment time. -- descriptionThe description/description !-- A short description, use etc. -- res-ref-nametheContextParam/res-ref-name !-- Specifies the name of the resource factory reference name.

You need to be sure that the following entries are in your hello-application.xml: application !-- The application element is the root element of a J2EE application deployment descriptor. -- module !-- The module element represents a single J2EE module and contains an ejb, java, or web element, which indicates the module type and contains a path to the module file, and an optional alt-dd element, which specifies an optional URI to the post-assembly version of the deployment descriptor. The application deployment descriptor must have one module element for each J2EE module in the application package. -- ejbpathToEJB.jar/ejb !-- The ejb element specifies the URI of a ejb-jar, relative to the top level of the application package. -- javapathToClient.jar/java !-- if you have an application client -- !-- The java element specifies the URI of a java application client module, relative to the top level of the application package. -- /module web !-- The web element contains the web-uri and context-root of a web application module. -- web-uripathTo.war/web-uri !-- The web-uri element specifies the URI of a web application file, relative to the top level of the application package. -- context-rootthedir//context-root !-- The context-root element specifies the context root of a web application. -- /web /application The module and web tags tell Orion to link these items together as an application.

Hi David,
Thank you for your help, this example code might be very useful. What
I'm trying to do is centralised login service, to allow a central
authentication service to control acces to different web applications
that can even be in different hosts. I already succesfully implemented
the login part, but now I want to be able to logout from all the
applications at once, and I also want to be able to trace in one place
the user movements through the different applications. That's why I
thought about using JMS to implement the communication between the
different applications and the central authorization site. My concern is
now whether JMS, specifically Orion's implementation, is mature enough
as to have all my applications depending from it. Or are JMS
implementations in general as inmature and buggy as Michel J. Cannon
stated?
Thank you again,
D.

You will need to define the JNDINames interface with the appropriate values
for its attributes.
Then any class that needs to send messages can extend MessageSender and use
the appropriate attributes
This works for me. Let me know if you still have problems or

If foo() is under a transaction then calling bar() from foo() puts bar()
under the same tranaction.
The question becomes does bar() really need to be public? Is bar() called by
the Foo client directly?

RE: Concurrency
Greetings, Unfortunately the only way to resolve your concurrency problem is to use an Entity bean containing you list. That way your Session bean acquires in its create and activate methods a reference to the list entity bean and releases it in the passivate and remove methods. Your Entity bean must have Transaction required as its property, which can be either container or bean managed. The entity bean is the 'critical section' and the transaction is the 'monitor'. When Orion supports (hopefully in the near future) EjbLocalBeans we won't be burdened with the network hit. See EJB 2.0 specifications.

Why can't I just set the host to the same IP address I used in the ipchains command above? 2) If I access the application on port 80, it works fine, until I call response.sendRedirect(somefile.jsp).

jsp:useBean Issue / Epicentric ?
First off, is anyone using Orion with Epicentric Foundation Server 3.5? If so, what version of Orion are you succesfully using it with? It seems that alot of the 'stock modules' (jsp files) and other jsp's that ship with EFS 3.5 aren't using bodyless tags, ie: jsp:useBean foo=bar/jsp:useBean and that Orion (?) is complaining about this: jsp:useBean without a set 'class' or 'beanName' attribute cannot have a body, use a bodyless tag (jsp:useBean ... /) Orion wants you to use a bodyless tag: jsp:useBean foo=bar / Question is, is there a 'legacy' switch somewhere that I can turn on that'll allow the JSPServlet to deal with bodyless tags. Or should I just patch all these .jsp files to actually be bodyless? I'd rather not patch because then I'll have to propogate my changes with each EFS update, and potentially patch other oddities as they arise. Env: jdk 1.3.1, Orion 1.4.5 through 1.5.2, EFS 3.5SP1 Any help is appreciated. -- David S. Kenzik [EMAIL PROTECTED] - http://kenzik.com Original Music - http://text.org

RE: problems with classloading and Clients, NoSuchMethodError
Erik, If you want to change classes without restarting the server than you must write your own application ClassLoader. What your experiencing is Java name space isolation. The Java name space is defined by the jar, class, and ClassLoader loading the class, which means that a change to anyone of the three constitutes a different name space. Since your jars and classess do not change, then Orion uses a different ClassLoader for your application and the rmi server. This is surely the case if Orion uses ClassLoader's default constructor for serving ejbs, compiled classes, and rmi requests. See Server-Based Java Programming by Ted Neward for help with what you want to do. Dave -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, July 24, 2001 1:44 PM To: Orion-Interest Subject: problems with classloading and Clients, NoSuchMethodError Hi, My problem is as follows. I have debloyed every EJB in a jar and deployed it properly in application.xml. I have for a number of reasons decided to have every EJB in one ejb-jar. All that works fine. I have an ant script that builds every ejb-jar and an jar called app.jar, this jar contains all classes not included in the ejb-jar files. The app.jar is deployed using library path=./app-lib/app.jar / in the orion-application.xml. I'm running an orionserver starting it with com.evermind.server.ApplicationServer in a shell script and adds all the 3party jar files (such as log4j.jar etc etc.) When I start the server it find all the classes and every thing works very fine. If I remove the the library path=./app-lib/app.jar / the ejbs do net get deployed because they lack a number of files (which is in the app.jar) this makes me belive that the deployment of the app.jar works. I then access the server using a client with RMIInitialContextFactory. I then get a NoSuchMethodError on the client java.lang.NoSuchMethodError at com.evermind.server.rmi.ba.invokeMethod(JAX)at com.evermind.server.rmi.a1.invoke(JAX) at __Proxy1.genericFinderVH(Unknown Source) at no.lindorff.kb2.core.client.ApplicantProxyManager.genericFinderVH(ApplicantP roxyManager.java:147) at no.lindorff.kb2.core.client.ApplicantProxyManager.main(ApplicantProxyManager .java:206) If I start the server when the classpath points to all compiled classes it works fine. The classes in the ejb jars and in the compiled classes are the same. If I put on java -verbose it looks like this error is thrown on the server but it does give me any further output. The class loading looks different and continues when I start with a classpath containing all classes If I use reflection and print out all methods on the remote interface the method is there. I do all this because I want to change classes without restarting the server all logs application.log rmi.log etc. tells me nothing. Is there no way to get more verbose output from the server? Has anyone any idea what I'm doing wrong and any points of what to do and/or test Regards Erik Romson
RE: Queue or Topic multicast?
Greg, Only Topic is multicast by specification. To keep all objects on the network updated, simply have any object that is subject to caching to publish the appropriate change-Topic message and those that are interested in the change subscribe to that change-Topic. There is basically two ways to propagate the change: 1) use a text message containing the database reference id so that the correct row can be refetched (IO expense) or 2) use an object message containing a DataObjectChangeEvent object with the old and new values so that the subscriber can determine which of its values change by check the old value (no IO expense). Remember all object of a class will be subscribers to the change message, which means that a subscriber must be able to determine readily (simply) whether the received message needs to be processed or not.

Re: Oracle deal gag
From: Jay Armstrong [EMAIL PROTECTED] EW, [snip] After my criticism, subsequent messages from others on the original thread (RE: Oracle deal) also went through fine, but none of them were critical of Ironflare. In fact, all of them either told me to shut up (Greg Stickley and Hani Suleiman, who described the problem as a pebble), were complimentary of the deal, and/or tried to change the subject. Seems odd to me that not one, single critical comment about the most important business deal in Orion Server's history came after mine, unless the thread was being censored. Have you considered the remote possibility that everybody else frequenting this forum might just happen to not share your opinion regarding the deal? I would point out one of Karl's statements in his reply to me: The purpose of the orion-interest has always been to promote the exchange of experiences and knowledge between our users, not as a channel to communicate with us. Sounds fair enough. Paying licensees enjoy the benefits of having a support channel directly to Ironflare. Non-paying users enjoy the benefits of having a public forum in which to discuss issues regarding the Orion product. The state being as it is, at Ironflare, with very few employees so far, and the focus being on development, I would find it surprising to see either Karl or Magnus spending lots of time in this forum. Should a significant portion of the users of this forum come to the conclusion that this forum is unfit for its intended purpose, there is a very simple solution: Start another one, e.g an egroup. I interpret the statement above to be a veiled warning that big brother is watching and not to criticize Ironflare via orion-interest. Oh dear. Let's see if this one comes through, to test the theory. Ironflare: - When it comes to announcing major changes and/or updates in the Orion product and/or the Ironflare company, you, at this time, suck! - Your official website is among the most static ones I have ever seen. You should put more effort in publishing current information regarding the product and the company on a regular basis, as in daily or at least weekly, on the website. If the irony wasn't obvious; I, for one, find the very idea that Ironflare would try to censor this forum ludicrous. I would be _extremely_ surprised to find my criticism above being removed for any reason. I would be happy to receive any feedback from Ironflare regarding it, though, but that seems unlikely at this time, this forum not being an official channel. I have found that an email directly to Ironflare tends to get more attention. I am not saying that I wouldn't like Ironflare to more actively participate in this forum. On the contrary, I think that would be great! But _not_ if it affects development and bug squashing adversely. _DO_, by all means, update the website more regularly, though! Don't you also find it odd that Ironflare did not make this announcement? Rather, it came from Bryan Young's discovery after trying oc4j. My guess is that Ironflare, possibly under orders from Oracle, wanted to keep this quiet and is now attempting damage control. Could you please elaborate on exactly how you came to that conclusion? If it's a list problem, okay, but how can we possibly know? Time will tell, though it could also be that open discussions are not and have never been allowed in this interest group. Ridiculous. It might be that I am a Swede myself, but to me it just seems totally unlikely, from what I have heard and read about Karl Magnus. Let's hope I am not proven to be wrong. That would be a sad day indeed. Jay Best regards, David

RE: Problem with @ character submitted in POST request through CGIServlet, TunnelServlet
Strangely enough, I ran into this problem yesterday. It seems that different browsers report the value of the CONTENT-LENGTH variable differently. for reasons I acn't conceive of, MSIE deducts 2 characters from the length it reports for each @ in the form output. Netscape does not. I don't know if the CGI servlet uses teh CONTENT-LENGTH variable to terminate its read of teh form output, but if it does, that may be where the problem lies. This may be a job for the folks at orion to look into.

What happens is: I have an HTML form which is transmitted via POST request. Two parameters are passed: email and action what should arrive is: email=peterb%40sbox.tugraz.at action=Login When perl gets the request the second parameter is truncated [EMAIL PROTECTED] action=Log This happens only if the first parameter contains the "@" character. I suppose the same bug affects the TunnelServlet too. I already informed Orion support about that some time ago, but didn't get a response, and 1.4.7 still doesn't correct this issue. For us this trivial bug is absolutely critical because we need to have orion handle requests and SSL in the front. Certain apps (the IMP PHP webmail) should be tunneled to apache, which still doesn't work! Other URL-encoded characters don't seem to have a negative effect, but the "@" causes the problem with the following parameter. I read on the list that also others have had problems with the Tunnel Servlet and POST requests. Maybe we can track down the bug a bit deeper. I entered it in Bugzilla as Bug Nr. 387 and hope that it finally will be taken care of. Regards, Peter ---
Simultaneous Username/Password Detection
I am building a system that protects content by username and password. No problem there. The more complicated part of the system prevents two people using the same username and password at the same time on our web site. I have a plan to do this, but I haven't seen if there are any common methods/techniques/strategies/design patterns to do this in a jsp environment. Nor do any of our developers have any experience in doing this. Currently, I am just going to store server generated sessionId's and userId's with other necessary data/time checks..of course the user must be able to take over use of that username and password because the browser may crash...or they forget to hit logoutand also I must flag when this happens too many times in a period of time as a red flagobviously with an html web site, there is no 100% accurate way to only have one user using the site at once, however, I can build it well enough that 95% of the users that are giving out their passwords won't because it is annoying to keep re-logging in and being locked out for an hour if you trip one of our red flags.thoughts? experiences?

Servlet Mapping Tag
I don't understand how Orion has implemented the servlet-mapping tag for the web.xml file. According to the documentation, I need to declare a pattern /*.thePattern. When I do something like the following, it works. However, I need a separate pattern for each servlet in order for Orion to invoke a unique servlet. My questions are: 1. Is the servlet-mapping tag necessary. (I couldn't invoke a servlet without it.) 2. How is Orion expecting this to be used? servlet servlet-namesnoop/servlet-name servlet-classSnoopServlet/servlet-class /servlet servlet-mapping servlet-namesnoop/servlet-name url-pattern/*.1/url-pattern /servlet-mapping servlet servlet-namedh/servlet-name servlet-classdh.TestServlet/servlet-class /servlet servlet-mapping servlet-namedh/servlet-name url-pattern/*.2/url-pattern /servlet-mapping

SV: Access EJB's from a standalone client.
I'm sorry I forget to tell you that you also have to add namespace access in
the application-deployments/yourAppName/orion-application.xml file too
(i.e on the server side only). Like this (in my case)
namespace-access
read-access
namespace-resource root=""
security-role-mapping
name="lt;jndi-user-rolegt;"
group name="administrators" /
group name="users" /
/security-role-mapping
/namespace-resource
/read-access
write-access
namespace-resource root=""
security-role-mapping
name="lt;jndi-user-rolegt;"
group name="administrators" /
group name="users" /
/security-role-mapping
/namespace-resource
/write-access
/namespace-access
Also in $ORION/config/principals.xml I have set up normal and admin users
and their passwords. It is this information that is put into the
jndi.properties file on the client side I referred to in my previous post.

RE: Faster encryption
I did a check upon the JSSE spec. It comes in two versions. One for the US and one for non-US countries. The international version does not allow other "service providers" to be plugged-in, thus I am stuck with the slow performance of the Sun JSSE implementation :-((( I hate it when those morons at the US export agency make every effort to hinder the spread of good technology :-( Seems we have to go for hardware encryption to gain speed or set up a cluster of, say, 8 PCs just to get acceptable performance using the JSSE with 128 bit encryption.

Default transaction isolation level
What is the default transaction isolation level for Orionserver? I would like to be able to specify this in datasources.xml, but it seems it is only specifiable in orion-ejb.xml, only pertaining to CMP beans and not session beans. The way think it works, Orion default to "Serializable" as CMP beans seem to obtain exclusive lock when simple getter methods are invoked. A too pessimistic approach IMHO (In my case this causes DeadlockExceptions) /David "The Las Vegas of Online Gaming" David Ekholm System Architect Hammarby Kajväg 14, 120 30 Stockholm tel: +46 (0)8 55 69 67 11 mob: +46 (0)70 486 77 38 fax: +46 (0)8 55 69 67 07 icq: 410993
Too many exceptions logged
I noticed that all exeptions generated from my EJB layer shows up in the application.log file. I actually only want system exceptions or unhandled exceptions to show up there. Is this configurable. I mean the fact that one of my business methods return a NotEnoughMoneyException should not make it into application.log but rather be handled by my web layer (as is the case). /David "The Las Vegas of Online Gaming" David EkholmSystem ArchitectHammarby Kajväg 14, 120 30 Stockholmtel: +46 (0)8 55 69 67 11mob: +46 (0)70 486 77 38fax: +46 (0)8 55 69 67 07icq: 410993
Deadlock exception when accessing entity bean
During heavy stress testing of my application I noticed that I get the following exception: com.evermind.server.DeadlockException: Transactions was rolled back: timed out, while waiting for primary key for one of my CMP entity beans here I can't see why this happens. The database has not reported any deadlock problem, and there is a row in the database for the primary key I am trying to look up. What can trigger such a problem. The CMP bean has no relations to other beans/tables what so ever, and just a primary-key index on the primary key. /David "The Las Vegas of Online Gaming" David EkholmSystem ArchitectHammarby Kajväg 14, 120 30 Stockholmtel: +46 (0)8 55 69 67 11mob: +46 (0)70 486 77 38fax: +46 (0)8 55 69 67 07icq: 410993

I'm really, really surprised no one's ran into this before. Everyone must use a jndi.properties file to set up their InitialContexts, not the InitialContext constructor that takes a Properties object. Unfortunately, that scenario doesn't work for me. :-( So, what's the normal resolution process here? It looks like it's probably a very simple fix. Will the fix make it into Orion 1.3.9 and then will 1.3.9 become the new stable version of Orion? Just wondering what the process is here.

For what it's worth, the bug is triggered from an application client. The bug also exists in Orion 1.4.0 and 1.2.9. The bug is *not* triggered if you never call close() on your InitialContexts, but I'm in the situation where my company's J2EE software component has to work with multiple application servers, so not calling close() is not an option. :-/ Thanks again. Here's hoping a fix shows up soon. :^) cheers, david -- David Sims [EMAIL PROTECTED] Sims Computing, Inc. www.simscomputing.com
Log Analysis
Anybody using standard tools to analyze logs? Anybody have the format string for apache's combined format set up? So it is a quick fix? David
Entity bean question
I wonder if the EJB specification guarantee that there is only one instance of an entity bean representing a particular row in a database? If so, does that also hold true for a cluster of EJB servers? /David "The Las Vegas of Online Gaming" David Ekholm System Architect Hammarby Kajväg 14, 120 30 Stockholm tel: +46 (0)8 55 69 67 11 mob: +46 (0)70 486 77 38 fax: +46 (0)8 55 69 67 07 icq: 410993
bug in Orion 1.3.8 when creating InitialContext
Hi OrionFolk :-)
Tonight I downloaded OrionServer 1.3.8 from the stable link off the
orionserver.com. There seems to be a bug having to do with
InitialContexts that was not there in version 1.0.3.
If you create an InitialContext object and pass in a Properties object
to the constructor containing the InitialContextFactory and so on, you
can successfully create an InitialContext object. Then you can call
close() on it. If you try to create it the second time, a
NullPointerException is thrown out.
Below is a small, simple class that definitively shows the bug. A
NullPointerException is thrown. The bug does not occur in Orion 1.0.3;
no NPE is thrown. Below my signature (see below) is the code and after
that is the stack trace.
I searched the archives and found nothing on this. Does anyone know
about this? Is there a workaround or some kind of fix? Any info at all?
thank you,
david

Re: Orion slow startup
What O/S are you using? If you are using Win95 or Win98 then it takes an age and then runs like a crippled dog. I agree with the Jikes suggestion - an absolute must. I would recommend removing javac from your system and copying jikes in its place. Full Stop.

Try configuring Orion to use jikes as a compiler instead of the standard jdk compiler. Jikes is an order of magnitude faster than javac.

Re: jdk version
Suresh Ajja said... Now recently i installed Jbuilder 4.0, which took jdk1.3 as default jdk ver.in built in it.from command prompt, I was not able to run my programs, hence I installed jdk1.2 after that, but now I am not able to run my Inprise server (jdk1.2.2 or later ver. not found error) .can somebody tell me How can i configure only one ver. of jdk to run my IAS as well from Command pr. In the jbuilder "bin" directory, there is a file called "jdk.config". It's self-explanatory-- you can set the path to your JDK in there. Just set it to the one you use from your command line.
