When to use java.util.Collection or java.util.Set
Hi everybody I noticed in the EJB 2.0 specification that most of the examples use java.util.Collection when defining a relationship between two entities, even though java.util.Set is also allowed. Why is that so? I would expect java.util.Set to be the most frequently used type, since in general you would not want duplicates in a relationship. Think of a Person-owns-Car relationship for instance you are not interested in any duplicates here, since a Person cannot own the same car twice so to speak (if one relationship says that person P is the owner of car C, it does not provide you with any usefull information to create yet another relationship between P and C). Which cmr-field-types do you use and why? Randahl
RE: Orion user management - NOT solved
Dear Elephantwalker As we all know, you are right that my session beans have access to a SessionContext, but I think this is not enough for performing the logout. As I mentioned, the user has been logged in by calling the login method on the RoleManager from a session bean, and this means that the user is logged in to the Orion server, he has a role and can access EJB methods and so forth. Now, to log him out again I have to tell the Orion server that he is to be logged out, so Orion will no longer allow him to access the EJBs which are protected by the security model (e.g. calling a method which requires the role Administrator). And to do this, I need some kind of logout method in the Orion API. It will not be enough to just alter the state of my beans (as mentioned by Peter Saurugger), because Orion will still think the user is logged in and has permissions to access my EJB methods. Now, you mention SessionContext are you thinking of the now deprecated HttpSessionContext which was available to JSPs? From that you could get a HttpSession upon which you could invoke the invalidate method. However, this is not possible with the object of type SessionContext which my session beans have access to. It has no getSession method or the like. I sure hope somebody can think of an answer to this issue. Either that, or I am stuck with making the client open an HTTP connection to call a servlet which performs the logout I would really hate that.

RE: Orion user management - Johan Frederikson comment
Well, Johan Frederikson and Peter van Rensburg, you both kindly mention the possibility of using the standard session.invalidate() for logging out the user. However, I think this would require me to write a servlet which (as we all know) automatically has access to the session object. This seems like a very strange approach to me, if one chooses to base ones system on Orions EJB-features and RMI only i.e. if you are writing a non JSP-system. In our design, our Swing-based client has a simple interface to the server consisting of a set of Session Beans upon which the client invokes a number of business methods. One of these Session Beans is used for authentication, so it has a login method and a logout method. It is quite easy to implement the login method since it can just delegate the work to the RoleManagers login method. But then when you want to log out the client, whps, there is no corresponding logout method on the role manager is that not a bit odd? Firing up the whole JSP/Servlets API in an EJB-only system seems a bit ugly, does it not? To put it briefly: Is there any good reason why the RoleManager does not have a logout method? is there any alternative?? I am very interested in hearing your views.

Is Orion JDK 1.4 compatible?
Hi I am wondering if anyone has any experience with using JDK 1.4 to run Orion I noticed that, the Orion installation docs mention using JDK 1.2.2, but is does not say that this is a requirement. I would like to run Orion with JDK 1.4 because then the new Java features like logging will be available to my beans, but I am worried that Orion has not been tested properly with this JDK.

Authentication
Hi Have anyone of you noticed that the RoleManager contains no log-out method this raises the question How do you log out an application (Swing) client? Randahl
jndi.properties and ApplicationClientInitialContextFactory
I noticed that when specifying the jndi properties in accordance with the orion documentation you include this line: java.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory Does this mean that the application client needs to have the mentioned class in its class path? If so, how do you make this class available to the client I think having the client application include all of the huge orion.jar (which contains this class) seems a bit awkward, and if you can use this class on its own I wonder why it is located in orion.jar.

Application client log in
We are currently implementing a Java Swing client, and I am wondering how to write the log in system.

Bidirectional N-M - when will it be ready???
Hi I was just wondering if anyone on this mailing list has a clue to when we might expect the bidirectional N-M relationships to work. Since the 2.0 version of the specification is final I expect the development team is working on these features. I guess we are waiting for several of the 2.0 features, but personally I am especially interested in getting the chapter 10.3.7.6 behavior (bidirectional insertion and removal) to work without having to program it myself. Any clues? Randahl
RE: bugs in @page extends=.... in Orion implementation?
Hi Juan I absolutely aggree, and it probably will be implemented at some point - giving us the chance to use it if necessary (and with causion). Having looked deeper into spec I think filters are definately a better solution - its just like the old debate about inheritance vs. delegation, the obvious idea is to use inheritance, but when you take all the details into account, you end up with using delegation (filters). One advantage being that the filters you develop can easily be combined or used in later projects. A nice feature it is!

Anything you can accomplish by using this new base class, can be accomplished by either using filters or by implementing your own security and session management thru Orion UserManager and HTTPSessionManager. Tough the earlier can be plugged in seamlessly, the latter doesn't have a configuration tag that allows it. The interface, however, is available since version 1.4.5 at least, and Orion uses it internally with two implementations, normal session and clustered sessions. I agree with you that the feature should be there, but it would be necessary only to work around (transient) web server limitations, and render the code unportable. It should be in orion, but must be used wisely.

Michael J. Cannon wrote: Interbase is not 'free.' Well, Michael, I already made a post of the parts in the Interbase licence that states that the database product is free. I think I read the licence very carefully, and as far as I can see, the licence is indeed free. The licence includes sentences like the ones included below, which states that one can freely use and distribute Interbase although one is not granted a patent right. This is, I believe, sufficient if you just want to put Interbase underneath your web application.

RE: orion + jbuilder4 -- sapdb?
I believe Interbase is totally free. For some reason Borland does not emphasize this very much - maybe to make sure people don't think it is a discount product. Interbase is released under a licence which besides the usual juristical mumbo jumbo says the following three important things: "grants You a world-wide, royalty-free, non-exclusive license" (...) "to use, reproduce, modify, display, perform, sublicense and distribute the Original Code (or portions thereof) with or without Modifications, and/or as part of a Larger Work;" (...) "under Patents Claims infringed by the making, using or selling of Original Code, to make, have made, use, practice, sell, and offer for sale, and/or otherwise dispose of the Original Code (or portions thereof)." And I feel sure that if it was not for these sentences there would not be an open source project based on Interbase called "Firebird" at http://firebird.sourceforge.net. - That's interesting by the way... when Interbase went open source Borland was slow on getting up to speed with the open source web community stuff, so the open source developers took the project elsewhere and renamed it "Firebird", which means that Borland has no control over what happens with the Firebird project. - Probably not what Borland expected at all. Now the developers at "Firebird" claim they have made a bunch of bug fixes which should be the reason to choose their product. Still, we are definately going to stick with Borland for now; after all they have many years of experience with developing the product, so having them control the open source effort somewhat might be a good thing. Hope this clarifies what Borland did not make obvious at their web site.

max-table-name-length - a bug or a feature?!?
When using max-table-name-length in my database schema Orion does not only truncate table names, it also alters them. I have a couple of beans which all have their own relationship to a certain other bean which has a long name. This should result in Orion creating the following tables: MyFirstEJB MyFirstEJB_theCertainOtherBeansIKnow MySecondEJB MySecondEJB_theCertainOtherBeansIKnow CertainOtherBean Where the tables called "X_theCertainOtherBeansIKnow" store the relationship keys. However, when these relationship tables have too long names Orion does not remove characters at the end of the names, rather it removes the bean name from the table name. So instead of a truncated name like "MySecondEJB_theCertainOth", I get this name instead: "theCertainOtherBeansIKnow". This is quite a problem since many of my EJBs have this relationship, and then Orion thinks it should create a table named "theCertainOtherBeansIKnow" for each of them, which it cannot because the table names collide. As a work-around I have decided to force Orion to use table names which I will specify in "orion-ejb-jar.xml". - But of course this is not very satisfactory. If anyone knows another solution to this problem or have any suggestions I would very much like to hear from you. Yours Randahl

Interbase and Orion / Falk Langhammers database schema for Interbase
Hi If you could give me any feedback about the following issue I would be very gratefull... I managed to get Interbase up and running with Orion. When I deploy, Orion creates my tables in the way I expected. However, when I start creating EJBs I get a javax.ejb.CreateException from InterClient. I create my EJBs from a JSP page which has worked fine on Hypersoniq. The exception on Interbase is this: javax.ejb.CreateException: Error creating EntityBean: [interclient] Invalid data conversion: Parameter instance Archive is out of range for requested conversion. See API reference for exception interbase.interclient.ParameterConversionException Now, such a conversion exception has to do with JDBC's conversions from Java objects to database data types. The instance I am trying to store is a simple bean containing only three properties: 1. a String as a primary key 2. another String 3. an int The only way I can imagine one of these values being out of range is if one of the strings were too long or the bytesize of the int could not fit into database type I have declared - I am using the database schema shown below which is based partially on Falk Langhammers post.

FW: Interbase and Orion / Falk Langhammers database schema for Interbase
Hi If you could give me any feedback about the following issue I would be very gratefull... I managed to get Interbase up and running with Orion. When I deploy, Orion creates my tables in the way I expected. However, when I start creating EJBs I get a javax.ejb.CreateException from InterClient. I create my EJBs from a JSP page which has worked fine on Hypersoniq. The exception on Interbase is this: javax.ejb.CreateException: Error creating EntityBean: [interclient] Invalid data conversion: Parameter instance Archive is out of range for requested conversion. See API reference for exception interbase.interclient.ParameterConversionException Now, such a conversion exception has to do with JDBC's conversions from Java objects to database data types. The instance I am trying to store is a simple bean containing only three properties: 1. a String as a primary key 2. another String 3. an int The only way I can imagine one of these values being out of range is if one of the strings were too long or the bytesize of the int could not fit into database type I have declared - I am using the database schema shown below which is based partially on Falk Langhammers post. If you have any ideas or suggestions I would be very happy to hear from you.

This installs Firebird as a Win2k-service. (7) Using Interclient configurator, configure Interclient (ie., Interserver) as a Win2k-service. Start the service now.

Are they still around? Hello all, I've been trying for weeks now getting any response from the orion team to no avail. First of all, I wanted to post a serious problem in Bugzilla but for that I need a account password. I've tried and tried, but never ever received a password after creating a new account or after requesting the account password to be send again. Then I tried sending a message directly to orion support. No response. Then I posted my problem to this list http://www.mail-archive.com/orion-interest@orionserver.com/msg09692.html (Serious problem with Orion transaction processing: multiple connections used within a single transaction) februari 13, 2001, including a test case. I mailed this problem again to [EMAIL PROTECTED] februari 19, 2001. No response. I mailed Magnus Stenman directly on februari 27 explaining these problems and requesting access to Bugzilla. No response. I'm not clear what options are left, but we are seriously considering other application servers right now as this kind of support is really not acceptable in the long run. At least a simple acknowledgment of the reception of the problem would give us the idea that someone is actually monitoring [EMAIL PROTECTED] mailbox. It doesn't seems to be the case right now. Having to switch to another application server is something I really don't like. Overall I like the orion application server very much (certainly for development). We consider the bug we encountered as very, very serious which will have to be solved otherwise we just don't have another option. The bad (non-existing?) support makes this truly serious. If anyone did have some contact with the orion team (mailbased or otherwise) in the last month's I would be very grateful to know how they did that. The same question I have for anyone how was able to create a Bugzilla account recently. Lastly, somewhat less important: does anyone receive the orion-interest maillist still directly to their mailbox? Since Januari 11, 2001, we didn't receive any mail anymore, and can therefore only access the maillist at http://www.mail-archive.com/orion-interest@orionserver.com.

Re: JDom and Orion
Well, David Kinnvall, did you ever get into any trouble from replacing the versions of Xerces and Xalan in Orion? Randahl Hi Mark, and the list, I ran into this as well, just two days ago. I tried putting the new xerces.jar in WEB-INF/lib as well as in orion/lib, with no effect. Finally I simply replaced the $ORION_DIR/xerces.jar with the new one as you are thinking about. It worked nicely, and I have not seen any ill effects from it yet. JDOM is very nice! I guess your question is still valid though: Are there any bad effects from doing this that will surface along the road that I haven't seen yet? Something that is not triggered by my current code? Or is Orion compatible with newer versions of Xerces? Oh, almost forgot, I took the opportunity to replace the old Xalan with the latest one as well... Regards, David.
Is Orion compatible with the latest versions of Xalan and Xerces?

Using multiple datasources
What is the simplest, most server-independent way of using several datasources with the same application? I would like a number of different customers to be able to use the same web-application, but with different database instances. It is important for me to use as few Orion specific features as possible - so far almost all my configuration lies in the standard xml-files as defined in the specification. However, it seems choosing a specific database instance is not mentioned in the EJB spec. Randahl.

RE: Error page
Hi Juan! My experience is that using an error page directive can take care of _some_ of the problems, not all. For now, I have simply put such a directive in each page, and quite often Orion shows my error page when an error occurs. However, if the error occurs on an included page, the contents on the containing page are often combined with my error page, which gives me a mix of two pages contents which all together is NOT valid XML. In these cases I bypass the XSLT processor by removing the page's link to it, and look at the source of the html to see the exception. I have not had time to solve this yet, but I was thinking of using a dummy error page containing a redirection header which would force the client to call a REAL error page which will be delivered with no page mixing. This would work, I think, but I would have to store the error information somewhere in between the two page invokations, which is maybe not that pretty after all. I will go ahead and make a post about this directly to the list. PS: I mailed this to the list aswell, as I think this is an important subject which should also be brought up on the list. Yours Randahl -Original Message- From: Juan Lorandi (Chile) [mailto:[EMAIL PROTECTED]] Sent: 6. marts 2001 19:53 To: '[EMAIL PROTECTED]' Subject: Error page Hi Randahl! I remeber you've had some problems with orion errors being invalid xml and you followed my suggestion of creating your own error page; I was wondering if you could share it with me(or some pointers) because I have the same problem now. TIA Juan
How can I prevent pagemixing when using error page directive?
A couple of us seem to have problems with error pages. I have a page A which includes another page B, and I have created an error page called "error.jsp" which is specified as the error page of both pages. However, if an error occurs on page B which makes Orion forward the request to the error page, I sometimes get parts of page A sent to the client along with my error page contents. When using regular HTML the problem is simply that the error page looks a bit odd to the user. But the problem is worse, when using JSP/XSLT, because the error page never reaches the user as the mixed page is most often invalid XML. Does anyone know a solution to this? Randahl

Request for your comments: Possible improvement of Orion CMP 2.0
I noticed that CMP 2.0 getXYZ-methods like customer.getAccounts() return a Collection which does not use isIdentical() to test whether it contains some element. I.e. when you invoke customer.getAccounts().contains(myAccount); this does not work. It seems to me that the collection returned by Orion is as incompatible with EJB as is the Java Collections Framework. This raises the question: Should not Orion return a collection which is compatible with EJB? - After all, it is an EJB server, and a pretty good one too, I might add. Yours Randahl
RE: Again EJB 2.0
Sounds like the database you are using does not support a type called "int" which you are mapping all "Integer"s to. You need to instead have Integer mapped to some 4-byte wide integer value supported, so you would have to check your database documentation for such a type.

We are trying to figure out if tag handler objects are re-used, or instantiated-and-destroyed at every request. This is obviously important for performance reasons. There is conflicting information in JSP spec and on JGuru (see references below). So maybe it's an implementation-specific issue. Which brings me to the question: What does Orion do with tag handler instances? Reuse or reinstantiate them? JSP spec 1.1, paragraph 5.4.7: At execution time the implementation of a JSP page will use an available Tag instance with the appropriate prefix and name that is not being used, initialize it, and then follow the protocol described below. Afterwards, it will release the instance and make it available for further use. This approach reduces the number of instances that are needed at a time. http://www.jguru.com/jguru/faq/view.jsp?EID=337618 Question We want to make sure that our JSP development efforts are thread-safe. Is it possible that two threads will access one instance of a JSP custom tag handler concurrently? No it is not possible. There is a defined lifecycle of a custom tag, and during this lifecycle, that instance of the tag will only get called once. Hopefully in newer implementations of JSP engines, the actual tag object will not get reinstantiated each time (as this negatively affects performance), but at least during it's use, it will be thread safe. -- Bart Blacha, Software Developer NetPerceptions Inc.

RE: Database schema type mappings
Thanks for your input. An additional argument here might be that if you are not the only developer working on your EJB system, and if the system is to be maintained and expanded over time by many different software developers in a large organisation, it would probably be best to use only a single type of key for the same EJB (both in the bean class files and in the xml files) - and that would have to be the wrapper class, of course. - All these mails confirm that using different kinds of keys cause confusion, and I see no reason to confuse future developers of a system. But that is my personal view of course - and from the systems I have met so far in my career I sure know that not all developers think this way.

So I went back and looked at the deployment descriptor (it was originally generated by EJBMaker) and noticed that they prim-key-class was "java.lang.Long". All of the EJB class files are using the primitive type. It appears that at least Orion maps them intelligently(if not according to spec). On closer examination of the EJB 2.0 spec, I found these statements. * The primary key type must be a legal Value Type in RMI-IIOP. (this includes long) * The container must be able to manipulate the primary key type of an entity bean. * Primary key (must be a class or type?) that maps to a single field in the entity bean class. * The (create) method must declare the primary key class as the method argument. According to this statements, the primary key class and the primary key type don't necessarily have to be the same.

RE: Database schema type mappings
The fact that you have found that quote in the book (even in the 2nd edition) definately indicates that at least at some point in time it has not been allowed to use primitive types as primary keys. Still, the specification is under constant development, and it seems to me the subject is deliberately ignored in the specification - in fact I did a search on java.lang.Integer and java.lang.Long and there is _no_ example what so ever which includes a primary key of neither the wrapper class nor the primitive type - odd... Perhaps it is avoided in the specification because it is subject to change. Personally I would like to here it from "the horse's own mouth" aswell - to be absolutely sure. We are definately not the only people who bumped into this issue. I am not sure your argument about EntityContext.getPrimaryKey() returning an object can be used here, though. Since EntityContext is an interface which is implemented by some proprietary class it is _possible_ that a container could construct the Integer object for you no matter what kind of Integer you are using. Please note the earlier post in this thread by Michael Third, too. He states they are using long's - so it works. And why not? - You can use any primitive type which is valid in RMI-IIOP, which for what I know includes primitive types aswell. Which brings me to my conclusion: Since this issue is unclear in the specification there is no guarantee that using int or long will work on any EJB Server. Therefore I will continue to use Integer to make sure my beans are platform independent. I personally go for a container independant system.

RE: need help getting started
I would definately *NOT* recommend moving away from Tomcat if you only use JSP and servlets. Tomcat is the reference implementation, it is free, and unless you need a product with a lot of additional features (GUI helper tools, EJBs, remote debugging, etc.) there is no reason to open up a can of worms. I really like the Orion server but that is for its EJB capabilities. I think the Orion team strives for making it a great EJB server. - The aim is not specifically to make it the best JSP/Servlet platform available, so I would not expect it to be ahead of Tomcat in that sence. Orion is a great product, but also a more complicated product, so if you can use a less complex system and still fulfill your needs, then I sure recommend you do so. However, should you get to the point where you simply don't think using just a relational database and several truck loads of SQL really makes your day, THEN JOIN THE CLUB - that is why many of use Orion Server and Enterprise Java Beans.

You are probably right. Still, I would very much like to hear from anybody who could prove you wrong. Having to use something like XMLEscaper.escape(Book.getPreface()) for all the output you take from your beans and use to generate XML really sounds like a mess to me. While we are at it: If you just *have* to do this conversion, why not do it when you put information into the beans rather than when you take it back out again... many systems on the web certainly have more content browsing than updates of content. Still, I sure hope this EJB/XML hindrance is just a rumour - somebody tell me there is a solution to this (!) Randahl
EJB values into xml attributes (a little off topic, I know)
PROBLEM I have a question regarding taking properties from an EJB and generating XML output. To explain, here is an example of my problem: poem title = "%= myPoem.getTitle()" %= myPoem.getContents() % /poem Because title is an XML attribute I think special characters like '' needs to be escaped with amp; and the like. How does one handle this in a nice way? BACKGROUND I can think of at least two solutions, but I was hoping someone could suggest a better one: 1: One could make sure to always store all content in the database as escaped content. This means that the title of myPoem could be stored as "Strength amp; Honour" instead of "Strength Honour". 2: One could require all get/set-methods to transform unescaped content to escaped content and vise-versa. 3: One could use a utility class with a static method: poem title = "%= Converter.convert(myPoem.getTitle()) %" . I know all this could work, but still I think it involves a programming overhead which I would like to avoid if possible. - Especially because I have found out I do not need to do any conversion for content which is not used in an attribute, e.g. myPoem.getContents() works fine no matter what it contains.
Database schema type mappings
If you look at the database schema in "orion/config/database-schemas/hypersonic.xml" it looks as if it is mapping between the primitive java type "int" and the corresponding database type "int": type-mapping type="int" name="int" /. In my EJBs my primary keys and other attributes are of type Integer. Since there is no mapping for class Integer one could think that Integers would be mapped to VARBINARY. Luckily my integers are mapped to the database type "int", but this makes me ask two questions: 1. Why is Integers automatically converted to int by Orion - and is this a standard EJB convention? 2. Would it be legal to have a primary key of the primitive type "int" instead of Integer? Yours Randahl

CMP 2.0
Would somebody please confirm that they have been able to use CMP 2.0 relationships on Orion, that they have seen them get stored in the database AND brought back into main memory correctly after a restart of the server. When I create a relationship it works fine until I restart - I simply can't make Orion restore my relationships from the keys it stores in the database. If I try the getX() / method of a cmr property it works - but after a restart it returns null. R.
CMP 2.0
Question A: Are the ones of you who are using CMP 2.0 using version 1.4.4, 1.4.5 or 1.4.7 of Orion? Question B: When _you_ use the uni-directional relationship-features does that make Orion create a seperate table for the relation or is the relationship stored as a serialized collection attribute (in the 1:N case, of course)? Question C: Would you mind posting an example of a unidirectional ejb-relation declaration that you have made work. Preferably both a 1:N and 1:1 relationship. A think the ideas behind CMP 2.0 are absolute magnificent, but gee, it has been a hard struggle for me to make it work on Orion :) . Often when I test my new CMP 2.0 application Orion simply just crashes - no error messages, nothing, it just closes. - I think I am starting to understand what was ment with "CMP 2.0 preview" as it says on the web site (LOL). Randahl
CMP 2.0: Yabbadabbadoo or not (?)
I have put quite an effort into making the CMP 2.0 features work, using both Orion 1.4.5 and 1.4.7 out of the box. I have narrowed my problem down to this: I have several uni-directional relationships, both 1:N and 1:1 and they seem to work just fine. For instance, when I create a new ejb A which knows another ejb B through a 1:1 relationship Orion stores ejb A along with the foreign key from ejb B. Yabbadabbadoo! However, my excitement comes to an end after I restart Orion. When I call A.getB() i get a null. - Orion does not use the key of B stored in A to raise an ejb of type B for me. Below is my ejb-relation definition - any hints would be G R A T E L Y appreciated. Thanks Randahl ejb-relation !-- this is the unidirectional relationship from many A to one B -- ejb-relation-nameA-B/ejb-relation-name ejb-relationship-role ejb-relationship-role-namea-has-b/ejb-relationship-role-name multiplicityMany/multiplicity !-- NOTE: I have tried both One and Many here -- role-source ejb-nameAEJB/ejb-name /role-source cmr-field cmr-field-nameb/cmr-field-name /cmr-field /ejb-relationship-role ejb-relationship-role ejb-relationship-role-nameb-belongsto-a/ejb-relationship-role-name multiplicityOne/multiplicity role-source ejb-nameBEJB/ejb-name /role-source !-- no cmr fields; unidirectional relationship -- /ejb-relationship-role /ejb-relation My ejb A is specified as entity cmp-version2.0/cmp-version ejb-nameA/ejb-name (...) persistence-typeContainer/persistence-type (...) cmp-fieldfield-nameb/field-name/cmp-field (...) /entity NOTE: I know "b" should not be mentioned here according to the specification because it is a cmr-field.

I have verified that if I don't, I get a deployment error (saying that getB() and setB() cannot be abstract methods for Orion to implement).
RE: EJB 2.0 CMP features of Orion
Thanks, Jeff for your many informative posts. I checked out the ServerTest.zip you posted and it seems my files look pretty much like yours. I noticed you had entered the abstract schema names of your beans, which I had not, in expectation that it would make no difference. I have now added such names too (just to make sure), however I am still working on getting my application up and running. I noticed in one of your posts (a reply to me, actually) you wrote: "Unidirectional 1-1 and 1-n relationships between EJBs work, but bidirectional relationships do not. There are easy ways to fake it, though." I too have been experimenting with bidirectional relationships by manually adding the relationship on both sides in my bean implementations. I have tried both defining my bidirectional relationship as two seperate unidirectional relationships which are the reverse of one-another, and I have tried to simply define it the way it is done in the specification. Interestingly enough, it turns out that doing this results in the same database tables, which made me expect that using the spec-way would probably be correct with Orion. I do not yet know what is wrong, but when I run it, orion hangs for quite some time and ends up returning an "out of memory" error with "no stack trace available". which brings me to: How have you made it work? Randahl
RE: http 500 errors
You would not happen to be using Internet Explorer, would you? If so, that is why you don't see the stack trace, someone mentioned earlier on. Go to the "Advanced" part of the "Internet Options" and disable the so-called "Show friendly http error messages". The so-called friendliness lies in the fact that the browser does not show the error itself, rather it shows an informative message to non-technical users about what they could try to do in case of the error, which occured. I is still quite a puzzle to me why this browser does not include a link to the thorough error information on the so-called friendly error pages.

RE: Win2k Pro. is mess... choosing the right database product
You are probably right in your asumptions. Might I ask why you have chosen to go for PostgreSQL? To me it seems a bit too uncertain to have two pieces of experimental software in one project. Personally I was thinking of switching to either MySQL or Interbase once my system goes on-line. I have used Interbase quite a lot, just not with EJBs, and it is totally free and open source nowadays. I have no experience with MySQL, but as far as I have read on this list, quite many people are fond of it, and it seems that the use of MySQL is a question of once needs for transactions (which MySQL does not support). I am wondering if anyone is using the prepackaged Hypersonic database in production... It has not given me any trouble during this development project... yet... - I would feel MUCH better about using a 10+ years old well-tested database like Interbase, and I simply do not know why more people are not using it.

Hi Randahl,
Why don't you just leave the method setBalance(float b)
out of the remote interface and put
public void setBalanceAndDoWhatHasToBeDoneWhenYouSetBalance(Float balance)
in the remote interface. So no other objects can call setBalance but only
setBalanceAndDoWhatHasToBeDoneWhenYouSetBalance(Float balance).
Greetings Wim Veninga.

Subject: No influence on CMP 2.0 getter setter methods - a feature or a bug?
I have been reading the CMP 2.0 specification and I think it is simply
great! Still, I am a bit surprised that the bean developer has no control
over what happens when a field is set. Imagine an AccountBean, for
instance:
public abstract class AccountBean extends EntityBean {
//implemented by the persistence manager
public abstract Float getBalance();
//implemented by the persistence manager
public abstract void setBalance(Float balance);
}
What if I wanted to do something useful when the balance was set? Say, I
wanted to add the account to a list of surveilled accounts if a negative
balance was set... it seems I cannot do that because the container
implements the setBalance() method for me. And I cannot just declare a
setBalance() method myself because I need the container's implementation
or
I will not be able to store the balance. H... it seems this is going
to
leave me with something like
public abstract class AccountBean extends EntityBean {
public abstract Float getBalance();
public abstract void setBalance(Float balance);
public void setBalanceAndDoWhatHasToBeDoneWhenYouSetBalance(Float balance)
{
//check if balance is negative and take action
...
setBalance(balance);
}
}
Now I have _no_ guarantee that nobody will accidently call the original
setBalance() method, thereby circumventing my little security system,
which
was supposed to check for a negative balance. But, hey, I thought, then I
will just declare the original setBalance() as protected - unfortunately
that is not allowed by the specification.
I would r e a l l y like to hear from anybody who knows a solution to
this.
Any comments would be most welcomed.

EJB 2.0 CMP features of Orion
Has anyone tried out OR-mapping of 1-1 relationships and 1-n relationships between two EJBs? I have seen Jim Archer's fine tutorial about EJBs having a 1-1 or 1-n relationship to a *dependent object*, but is the same thing possible between two EJBs? I know the web site states that Orion 1.2.9 does NOT support n-m relationships, but is 1-1 or 1-n supported in the latest release, and is the support for 1-1 and 1-n in accordance with the specification?

RE: Best practices: How to initialize state in EntityBean's super class
Thanks for your reply. I think you are right about naming the pseudo-method
"ejbCreate()" - makes good sence. I could not help noticing, though, how you
set states=null in some of your methods... I don't think that is necessary.
If you'd like the Vector called "states" not to be stored just declare it as
transient Vector states;
Actually I found a place in my own code where I forgot to put the transient
keyword in front of a variable which should not be persisted by Orion and it
works anyway, but it should be corrected, as the fact that it works may very
well be Orion specific.
See section 6.4.1 of the specification (I looked it up in the 2.0 spec but I
think it is the same in 1.0).
Yours

Subject: RE: Best practices: How to initialize state in EntityBean's
super class
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;
}
}

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.

Maybe it is a matter of taste, but it seems a little less elegant to me to develop my JSPs directly in the middle of Orions file tree.

I am hoping someone out there has already encountered a similar problem and can point me in the right direction in solving mine. The issue is that my custom JSP BodyTag is a wrapper around JSP Code producing UTF8 Encoded XML Content. Portions of this content is encoded in UTF8 because they are language resources and this is the only way they can be represented (e.g. and ? ). My JSP Body Tag Implementation takes the produced XML Content and processes it against an XSL Style Sheet to produce the desired display content. However, the UTF8 Characters are being munged and not displayed correctly. The crux of the matter is how do I maintain the encoding of the produced XML between the page being processed and handing it of to the XSL Parser for transformation. Currently I am trying to use something of the nature: StringReader xmlReader = new StringReader(bodyContent.getString().trim()); InputSource xmlInputSource = new InputSource(xmlReader); where the bodyContent is the standard internal JSP Tag extension member variable. I then used the created InputSource for any XML operations, but my content still has munged UTF8 characters. Anyone have any suggestions?
