Re: Does any one else see any problems with latest PDF2?
It looks like you're right, which (looking at our typical deployment organization) makes the spec completely unsuable in that regard. could you crosspost your email to EJB-INTEREST? It's more likely that you'll get a response from an expert group member. I sure hope we're both missing something. Regards, Robert At 14:38 27.04.2001 , you wrote: Looking at the latest spec PFD2, it appears that it is not possible to establish a unidirectional relationship between two entity beans in separate ejb-jar.xml files. With the removal of remote-ejb-name as a possible value for role-souce it makes integration of two packages impossible without the mess of taking and trying to merge two ejb-jar files into one. Scenario 1: We are developing an general accounting package. Our clients need to integrate with our package by establishing uni-directional relationships from their CMP Entities into what we provide them. Since they will not be altering our ejb-jar (except for deployment) how can they reference our beans? Scenario 2: Our accounting package contains a good number of CMP Entity beans. Since EJB A relates to B, and B relates to C, and C relates to D and E, and E relates to G and so on. It is not possible to separate the ejb-jar into multiple, smaller, ejb-jar files for the purpose of managing and controlling change. With over 100 EJBs a single ejb-jar becomes very unmanageable.

RE: WE NEED NEWS! We need to know Orion is alive well!
guys, as someone who has been dealing with theses issues for over 1 1/2 years of using orion (1 year in production for a number of applications) I would just advise you to save your breath and make your decision based on what's there now. several people (including myself) have made pleas like you a number of times and not much has changed but I (or better we) have decided that orion has reached a level of maturity that is ok for us and that it is an unbeatable deal for certain requirements if you can live the risks that are certainly there. we now know, which features are reliable and we stick to using those only. there are probably a number of major bugs still waiting to be discovered which might cause serious problems in your projects without any guarantee when they will be fixed. my advice is, set up your system, test extensively and then decide whether to buy or not (if you can afford that approach, of course). if you cannot live without that extra bit of security, you'll have to spend a heck of a lot more money for similar features. it's a trade-off but don't bet on anything happening at ironflare that hasn't happened yet. best regards, robert At 22:48 05.04.2001 , you wrote: I'd confirm the concerns listed below.

Re: HELP: Settings for pooled datasources, timeout errors
snip I'd like to know if i did not get something regarding the configuration of datasources and if others had problems with the timeout settings. Hi Jens, I believe your observations are correct and your not doing something wrong. We have also had a number of strange effects in that area but unfortunately not been able to construct an easily reproducible test case, which IMHO is the only thing that would make magnus or karl have a look at that. I believe that the core connection and transaction handling code is not rock-solid and does break under some exceptional circumstances. btw, most of my problems also happen when doing large bulk updates using ejb. IMHO an additional parameter that should be in there is a max-number of statements that can be issued per connection, before it is reopened by orion's pooling software. that way one could configure stuff conservatively without degrading performance significantly. Of course that makes their TX handling code a bit more complicated but as your case demonstrates, these things are necessary or at least very helpful in the real world. If you can set up a simple ear that demonstrates your problems, I'm sure they will look into it quickly, at least that has been my experience. Hope that helps somewhat, if not, see it as a sign of support ;-).

Re: Source available and sun
we've had this dicussion many times before. they (Orion team) have decided to keep it closed-source and it simply is their decision (apart from the legal stuff with sun, which I personally never bought as the primary reason not to make the source available without an NDA). the arguments (debugging parallelizes well etc. etc.) that have been brought up are valid and I'm sure they know the trade-offs very well but at the end of the day it's their baby. I'm not saying I'm happy with their decision but I do respect it. regards, robert At 08:21 24.02.2001 , you wrote: I must admit -- I am still confused about the Sun agreement preventing a J2EE server from sharing the source code.

Of course, the open source EJB servers, like openejb, Jboss, and jonas, have the source code available. So why would this be good for Orion or anyone, when Orion has such brainy people building their product? If you don't think they are brainy, the download the Sun spec for EJB and try building it yourself. The answer lies in numbers.

a pooled Oracle connection.
there is some shared library missing for your OCI driver. if you're on a
unix system check if your $ORACLE_HOME/lib is in the LD_LIBRARY_PATH your
orion instance is using.
if this doesn't make sense to you, use the thin driver and you will be OK.
no orion problem just your local oracle client setup.

This is in my data-sources.xml:
data-source
class="com.evermind.sql.DriverManagerDataSource"
name="Oracle"
location="jdbc/OracleCoreDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OracleDS"

connection-driver="oracle.jdbc.driver.OracleDriver"
username="store"
password="store"

inactivity-timeout="30"
/
This is in my EJB:
Context ctx = new InitialContext();
DataSource dataSource = (DataSource)ctx.lookup("jdbc/OraclePooledDS");
Connection con = dataSource.getConnection();
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select description from attribute_type");
if (rs.next())
blah = rs.getString("description");
st.close();
con.close();
And this is my error message, which occurs on the getConnection() call:

Re: Sybase experience anyone?
At 18:58 20.01.2001 , you wrote: Hello, We are about to decide about the database platform on which we will deploy our first J2EE application. Preferrably, it should be a cost-free solution. First I would like to ask if anyone has experience to share about using Sybase 11.0.3 (the one that is free to deploy under Linux). I especially wonder about the JDBC driver (does it come with one?). I have read about people using Interbase and PostgreSQL successfuly. I would still like to conduct a shootout between the following databases: Interbase PostgreSQL Sybase 11.0.3 SapDB We've had (/have?) the same problem and we settled for sapdb if nothing unexpected happens. Reasoning: - We don't trust Postgresql to be as mature in areas like backup, mirroring as one of the commercial products (anyone comment on that?) - Worked with Adabas for the past three years in production and never had a significant problem (one year in combination with orion). We were only pissed at how unprofessionally Software AG handled development and support for Adabas Tools and drivers (JDBC and Perl). Now that that seems to be a lot better with SAPDB (basically being the same as Adabas, I think you told me that Christian, thank you again for that hint :-) we only have minor things that make SAPDB less fun to work with than Oracle (by far the best RDBMS I've worked with but you know ...$$$). - Sybase worked well in our tests here too but we thought what could happen when at some point Sybase decided not to support this (very old) free version with new versions of JDBC drivers. Probably not relevant for the next year or so but you never know. SAPDB feels a safer choice in that regard. - A very individual reason. We have Adabas know-how and experience here and the basic concepts are exactly the same, so we don't have to make all the beginners' mistakes again with a new RDBMS. - Interbase (on linux) initially worked very well (also with orion) but proved to be VERY unstable (especially the JDBC driver) The only thing we haven't decided on is a low-cost failover solution for the database.

RE: Any news from Orion yet??: Rebuttle...
At 08:41 15.01.2001 , you wrote: Not to sound like a hipocrat but I believe the J2EE standard calls for a pplication server independence flexibility. You must think to yourself what makes your application so dependent on the server it is deployed onto. Besides the custom deployment descriptors (orion-ejb-jar, weblogic-ejb-jar, jboss, and so on) you should architect your system independent of any app server dependent features like clustering, fail-over and load balancing. If you sit down and outline the layers that are dependent on the underlying mechanism, you will be able to isolate and separate your application. Do you rememeber that Java is supposed to be independent of its OS? LOL So, coming back to my point: even if Orion does go under, you should be able to switch out to another server and modify some deployment descriptors with no problem. I have my application running under Weblogic, Orion, and Jboss with only the deployment descriptors different. no shit? seriously, of course, it is possible to deploy simple applications independently on different J2EE environments and of course one should use server-dependent features. I don't know what your level of experience and the complexity of your application is but it doesn't sound like you've been involved in the development and maintenance of a large number of complex J2EE projects (and that is not meant as an offense). First of all you obviously didn't read the cost factor (primary reason not to deploy on WLS for us). I'll give you some examples of things that one (or more precisely we) has to consider or do when moving to another server: 1. we have a homegrown code generation software that generates all entity beans, all deployment files and some more stuff. has to be modified for the server dependent parts of the config 2. database based web authentication has to be moved/ported to the mechanisms available for a different J2EE server 3. procedures/scripts for moving from development to production site, CVS management of sites etc. would all have to be changed according to the new configuration requirements 4. all people involved would have to learn how to work with the server 5. system administration scripts/procedures (including monitoring) might have to be changed 6. All http server specific stuff (filters, virtual directories) would have to be ported to the new http server 7. all tuning aspects not covered by the spec like transaction-timeouts, datasource-pool configuration etc would have to be migrated Regarding cheap alternatives there are additional things: - If you rely on a fast CMP engine JBoss is not an option (yet) - How fast does jBoss start with about 30 applications deployed (with about 15-30 EJBs each) the integration with TomCat or Jetty is alpha.quality? I'm not saying that half a year from now things might not be different but believe me, we've looked into that quite thoroughly. Of course, it's all doable but add that up for about 30 productive applications distributed on 3 production systems with more than 20 lines of orion-specific deployment information add the testing you need (remember, that stuff is in production now) and then consider than none of our customers would pay a penny for that because we recommended orion and then add the fact that we have to take the manpower for that migration from current projects. now is that a considerable price to pay for moving to a different server or what? we have architected the apps very carefully to be as little orion-specific as possible but there are some things that are simply not covered by any spec (see above for examples). no doubt that this wouldn't even be doable if we hadn't coded to the specs but it still is serious and expensive work. so that java 101 "but isn't it supposed to be WORA" just doesn't cut it in real life. hope that clears up the confusion and the scope of the statements in my earlier mail. best regards and no offense, robert I hope this helps and triggers some thought.

RE: www.orionserver.com down again
+1 from here too. Most problems with orion stability on our production systems were caused by buggy linux VMs. Even now with jdk1.3.01 from sun the VM crashes from time to time. In terms of long term stability, I think orion has become very good. The problems we've had with orion freezing were all triggered by rather extreme conditions (e.g. massive batch operations on ejbs causing OutOf MemoryErrors).

Re: Large Collections
At 17:59 07.12.00 , you wrote: We're working on an ecommerce site which has a rather large ( 3M) record products table. We were hoping that the Collection which is returned when an entity bean's collection field getter is called would be smart .. that the entity beans would be instantiated as needed vs all instantiated at once. Alas, it appears that this is not the case. I initially ran out of memory trying to get the collection until I applied the ApplicationAdministrator.flushEJBCache hack, but the elapsed time is still just too large when dealing with that collection. My question is how are people handling this kind of problem? Should I just abandon CMP for this stuff and do it in a traditional fashion, perhaps a temporary table, via JDBC? Maybe cache the handles from the CMP collections for reuse? Go for a database specific solution? IMHO you have to abandon CMP in that case as orion gives you no way to configure the behaviour of a particular finder. in many cases orions way of doing it (fetching all records) results in great performance but for 3M that obviously hits a limit. I don't know which appserver gives you that kind of control (I think inprise lets you decide whether a finder fetches the data or just pks). It depends on the kind of client you use, what's available as a solution. Probably the most robust way is using RDBMS features like limiting the number of records in the resultset and perfom a query against the db when the subset the client looks at changes. What do you want to do? Just iterate over all or present a subset to a client (e.g. browser or swing app) to select an entity? regards, robert tia john d (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

memory consumption problems
Hi, Is there any way to influence orion's way of handling memory consumption? I have a production installation that frequently crashes with java.lang.OutOfMemoryErrors although I've set the jvm to -Xmx400m. Resources never seem to be freed. This sounds similar to the problems someone else reported a short while ago. I'm also doing massive batch updates using CMP. It could be an explanation that entity beans are never cleared from the cache. I'm reluctant to putting in code that looks up internal orion objects to flush the cache. What I need is a config option for that (cache parameters, can't be hard to implement). Anyone knows a solution to this dilemma? As it is now, orion frequently crashes and the bad thing is, that in contrast to real vm crashes the supervise tool we use to supervise and restart orion doesn't detect this, which resulted in several very awkward situations.

Re: Anyone heard from evermind?
Hi Karl, good to see you're still alive ;-). snip/ I will try to keep you posted on these developments and I want to reassure you that we are not gone, but quite the opposite, we are making a move to become more aggressive in the future, but it has made us less visible for some time and has hurt the product development and release cycle, and it is likely to do so from time to time as we go ahead. A new release with a few fixes shouldn't be far away now though. can we read this as a committment to fixing bugs in available features before adding new features (like finalizing EJB2.0 and servlet 2.3 support)? I don't know about others but we are currently facing a rather tough time with the number of outstanding issues regarding stability and robustness. If you're admitting that development resources will be short for some time to come, then I think/hope that this is the only way to go, if you're serious about supporting your current userbase. I'm sorry that I have to say it this way but anyone in the business knows how hard it is to convince people to use an underdog product and I've been taking punches from customers for a while now.

Shipping the source makes it relatively easy for the competition to copy the product which of course is the downside. But I think shippingg the source would be for the better of the server. Nobody is perfect and if all of us have our hands on the source lots of those silly bugs should be fixed in much less time. Having to submit a testcase makes for a lot of effort on both sides since we have to create a testcase which has to be recreated by the orion team and tested. Most of these bug however would simply appear running your app through a debugger and jumping into the orion source. I've run into so many weird and absurd problems in Orion; all it would've taken for me to solve the problem and submit a patch would be a grep in the source tree. Alas, I cannot do this and I am stuck with an application server that has many advantages and many disadvantages, which more or less cancel each other out. Many bugs I post as problems to the mailing list, many times without response, forcing me to submit some of them to bugzilla, where they go unnoticed. Evermind's position, as stated on the FAQ, is that they would be SUED by Sun if they made their source code public. Well, I wonder what projects like Jonas, EJBoss and JBoss do? I know that there are legal issues with sun but so far I have yet to hear a statement from evermind saying "yeah we would really like to ship with source and talked to sun but they wouldn't let us". I personally would love to trade offical J2EE branding (if that's the legal problem) with being able to do something about really awkward situations caused by unexpected bugs. I think they have made up their mind not to give source away and that's a decision I as a customer must respect but it has the potential to make me abandon a (generally great) server. I don't think legal issues have really been considered seriously (might be wrong though). main problem is that they (evermind) don't want it. nobody forces them to obfuscate their code (or is there such a statement in sun's J2EE license?).

Lately though I haven't seen either Karl or Magnus on IRC chatting, nor have I seen an email in the list from them on any regular basis. I know myself and a few others are offering a good set of frameworks to be shipped with Orion and haven't heard a response in over a week of submitting the proposal. The frameworks would benefit Orion in that it would be like the big boys..offering more than just an app server. We would fully document them, support them, and they are open-source, so unlike Orion, if anything goes wrong, they are fixable by the ones using it. I quite agree that Orion should make source available for the use of allowing us to fix bugs if they crop up, and submit them for the Orion team to examine and if its a good fix, put it in the next build. This would require more people however..managing a product like Orion with lots of bug fixes coming in, merging them, testing them and so on..that would require alot of managing, and I get the feeling Magnus and Karl would rather write code than integrate fixes from many other people. I strongly disagree. let's compare what happens now and what would happen then. now: I try to describe the problem that causes the bug to show maybe add some pseudocode and maybe even package an application with instructions how to reproduce the bug. they have to go through that maybe program a test case or at least install my test application and then start looking. then: I'd do all the stuff myself until I see that there is e.g. a wrong conditional at line xyz and submit the line number of the file with a description of what is wrong and why. I would say that I as a developer would be much quicker with the second kind of information. I'm talking about many very obvious silly bugs that you see when someone points you at. the hard and tedious(==time and resource consuming) part is nailing it down. not understanding it when someone points you to that. of course there would be bullsh*t bugreports also but that's also the case without source. parallel development doesn't scale well but parallel debugging scales extremely well (linux, apache being the best example). it's many people stressing the software being curious enough to dive into the code to do work (find bugs) that would otherwise have to be done by evermind. people (mostly highly qualified techies) work for you for free to get a stable and mature product.

Re: EJB using core classes?
snip/ At any rate..my main question here is, the EJB class in the jar file is referencing the core class. I don't have the core package in the jar file. I thought if I deployed the jar file into the same web-app as the other classes were in, it would have access to these classes. I compile classes to WEB-INF/classes. Is this not the case? Is there some trickery to getting EJB classes to see the WEB-INF/classes? no, it's impossible and not meant to be that way. two possible cases: - your class is not application specific but a general utility in which case you could put it in a library that is specified in the library path of global-application and therefore visible for all web an ejb modules in all application or you have to explicitly put it where the ejb code gets it - it is application specific and used by both web an ejb then you have to put it in a separate jar which you reference in orion-application.xml (or the dir it's located in, look at the library element) and it will be visible to both ejb and web modules.

does anyone use the parent attribute for applications?
hi, I started using the orion feature, that you can declare a child application of another one. at first it worked fine but I'm beginning to get more and more weird errors, e.g. say I have three applications named parent, child1 and child2. in addition to that I have used the global-application to import some common utility classes used by all applications. when I start orion I get an error message saying that one of the utility classes (in the library path of the global application) cannot be found when deploying child1 and child2: Error loading package at file:/home/krueger/devel/projekte/s7procurement-deployment/devel/ejb/, Error loading class 'com.signal7.procurement.ejb.administration.CompanyBean': java.lang.NoClassDefFoundError: com/signal7/ejb/EntityAdapter when i remove child1, child2 from server.xml store, put them back in, they deploy normally and work. on another orion installation I have the effect that the narrow operation on a looked up home interface leeds to a class cast exception because there is an object of some internal com.evermind.server... class instead of my home interface wrapper. the identical deployment settings, freshly checked out from cvs work well on the same version of orion on the development machine. suddenly after a few requests on the servlet it works. before I incest more effort trying to find a pattern in this weird behaviour I would like to hear from others who have used this stuff if they think it works. if I'm the first to use it extensively I don't know if I have the nerve to go on and would consider solving my problem some other way. any input appreciated, maybe magnus or karl could share some internals on how this parent/child/global application stuff works internally (classloader hierachy, jndi tree, implications) so I can bo better than with just brainless trial and error. robert (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

DirView which contains all the attributes of your Dir EJB. Then
make a single call to the Dir EJB to get a DirView. This will cause
only 1 RMI call and save you a huge amount of time.

We have implemented our own usermanager, and it all works great. But we

We start up a 'raper' thread, which is responsible for cleaning up expired

the usermanager, and there is know way to kill the spawned thread, so after
several restart(in development mode), these threads get crazy. I would
love to see a shutdown hook added to the AbstractUserManager class. Anyone
else have a need for this? Anyone else have an idea how to get around it?
you could put the code that inititates a cleanup thread in a method of the
usermanager that checks when the last cleanup has been invoked. this will
be more robust and won't give you a noticable performance penalty. It's not
that nice (sort of a heuristic approach because it relies on the fact that
getUser() is probably called often enough to ensure that your cleanup works
reliably).
pseudo code:
getUser(String userName){
if(lastCleanupWasTooLongAgo()){
doCleanUpActionAsyncronouslyAndSetTimestamp();
}
return getCustomUser(userName);
}

Re: Web upload of a Java class
oh, I see. that's something the servlet api doesn't do for you. to parse a
multipart request (that's what you use for file-upload) all you get is an
input stream that you can parse which you have to decode. however there are
plenty of utilities that do this for you. one is even shipped with orion.
check the api docs for FilePostParser. there is a source example of how to
use it.
just get the request input stream, apply the parser to it (again gives you
input stream on the decoded data items) and store copy the data from the
input stream to a file.
remember to set the form enctype to multipart/form-data.
that should be all you need to get going.

Re: 1.4.4 OR Collection classes
Unfortunately it is not always clear whether an object referred to by its interface type is serializable. I am in the middle of fixing a load of beans that returned Iterators, which worked fine on Orion 1.3.8. Of course Iterator is an interface, and I discovered when I upgrade to Orion 1.4.3 that the objects that backed the Iterator objects returned by JDK 1.1's Vector and JDK 1.2's ArrayList (etc.) were *not* serializable. well, that's perfectly ok because Iterator or ListIterator is not serializable either. Return collections from your beans. So orion let you get away with a design error (which is bad, I admit as it should have detected that the reurn type is neither a remote object nor serializable, shouldn't it?) but it remains a design error on your part. robert (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

RE: 1.4.4 OR Collection classes
did you file this as a bug report in bugzilla? I didn't find it there. I'll file it now (we just ran into it and it's a nasty one to find). if you already have please contact me so I can remove it. robert Vidur, This looks in same ways similar to the problem that I reported a couple of days ago. That is, Orion 1.3.8 allowed non-serializable objects to be returned to the client if running in the same JVM (which should of course not be allowed). 1.4.3 on the other hand behaves differently - rather than throwing a java.io.NonSerializableException (?) or something like that (which I suppose would be correct behavour although I haven't looked in the spec), it just returns a null and says nothing. Perhaps you are experiencing this kind of problem? Unfortunately it is not always clear whether an object referred to by its interface type is serializable. I am in the middle of fixing a load of beans that returned Iterators, which worked fine on Orion 1.3.8. Of course Iterator is an interface, and I discovered when I upgrade to Orion 1.4.3 that the objects that backed the Iterator objects returned by JDK 1.1's Vector and JDK 1.2's ArrayList (etc.) were *not* serializable. I found it useful to use an ObjectOutputStream to write the returned object out to System.out, wrapped in a try-catch block that printed the stack trace. The resulting exception messages told me what the offending classes were (for example java.util.AbstractList$Itr, and also RuleBasedComparator which I had been using to sort sets). Maybe this is totally unrelated but the symptoms seem similar enough so I though I'd mention it.

RE: BMP vs CMP with Orion
At 22:23 05.11.00 , you wrote: My personal trade off was: Why not CMP 2.0 style: - Too scared to use it for real as it is not even officially there ... Why choose for CMP 1.1? - CMP is more portable (across db's). - Working already towards EJB2.0. - The claim is CMP can be optimized better (I would be happy to know more details about that, until that time it is a bit of a bet on a blackhorse for me). check the archive of ejb-interest. bottom line is that the server can cache or prefetch data from resultsets that bmp doesn't allow. bmp typically results in many db accesses for finders (retrieving pks and subsequent ejbloads) where a good cmp engine just uses a few. Why choose for BMP? - I do not know yet whether I'll run into trouble with complex and highly flexible queries requirements for Query By Example forms. The requirement for extra flexibility could become an argument. it is not an either-or decision. mix them as you like (typically simple stuff cmp, complex stuff sometimes BMP sometimes jdbc wrapped with a session bean). you don't decide to use either a hammer or a drill to build a house ;-). I would say if you can spend the time learning enough about CMP 1.1 I would go for that as a first option. The EJB1.1 specs are even written so that you can sub class a CMP bean to create a BMP bean. One of the biggest disadavantages of EJB's is the tremendous amount of redundant code you have to write. Add for instance a field to a bean. You'll have to change three files minimum and don't make mistakes as that will cost you time. This disadavantage applies to both CMP and BMP and will apply to EJB2.0 as well. What I'm doing is using EJB1.1 CMP and generate beans and stuff using a slightly more advanced bean generator then the standard ones. Based on a datamodel (Entity-Relation) it generates a set of beans for your application (including the remote and home interfaces and the *.xml files of course). The generated beans include the fields, the finder queries, the additional methods to retrieve related beans etc. same approach we use and we're quite happy with that too. As an additional bonus the beans include a more abstract way to access the properties (myBean.getProperty(int index)) as the client side of orion does not allow reflection. I use that to generate forms and tables on the client. The generator adds a tremendous flexibility (I can switch to BMP / EJB2.0 easily), makes CMP 1.1 managable and keeps me away from EJB2.0 while it is still too early for me. For the rest: Im a notoruios mifftyper and am able to spend tons of time debug typos in 2638 lines of very closely resembling code.
