Questions about JNDI Initial context
Hi, I already saw a lot of questions/answers about that in the mailing archive but none of them really answered the question so I'd like to evaluate the web-tier of Orion using an existing EJB application running on weblogic 6.0, I already did the same thing with Tomcat and in that particular case the only thing I had to do was to add the following parameters when I started the Tomcat servlet engine. -Djava.naming.factory.initial="weblogic.jndi.WLInitialContextFactory" -Djava.naming.provider.url="t3://localhost:7001" and it worked fine. So my question is, will it work the same way if I add those parameters when I'llstart the Orion server ? I read a lot of stuff about jndi.properties file and I'm still not convinced about the utility of this file and also where to place it. I do not have a lot of time to test that for the moment, but I'm sure I'll have to do it in the future so I'd like to get already an answer.

Remote JMS access

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.

orion.jar needed for JNDI-lookup??
Hi everybody, we are running a Swing-application accessing via HTTP/RMI to an EJB-server. To do the JNDI-lookup class "com.evermind.server.ApplicationClientInitialContextFactory" is used as describes in the orion-doc. The problem: this class is located in orion.jar (2.sthg MB), which is after my understanding the main-lib of the whole orion-server. Consequences: 1) we don't want to ship this lib to the client (system uses Java-Webstart to download all classes and libraries needed, even if Webstart only updates classes which are changing this is way too much download for "some JNDI-lookup") 2) how can this conform to the licence-model of Orion when you have to ship the application-server to the client (for each client-installation, which in this scenario comes up to several hundred) If I should have missed sthg. in the doc, sorry for this. If not: how to deal with that since this a pro/con-decision for our customer using Orion. Thanks Cheers, Stefan Wendel, [EMAIL PROTECTED]

RE: Orion as a Win2000 service ?

Hi Stefan, we are running a Swing-application accessing via HTTP/RMI to an EJB-server. To do the JNDI-lookup class "com.evermind.server.ApplicationClientInitialContextFactory" is used as describes in the orion-doc.

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

Subject: RE: simple JSP bug with switch
It appears to me that Sun's RI is recognizing the obvious - that statements
can not appear between switch and case, nor between break and case.
Unless the spec specifically addresses this, it seems that Orion is doing the
correct thing, and Sun is providing a nicety that lulls one into writing bad
JSP code.
tim.
Sorry if I didn't quite get your point.
It's odd though. The spec VERY specifically says that whitespace must be
preserved (JSP 1.1 spec, section 2.1.6), so it seems to me that what Orion
is doing is correct, even if it seems inconvenient.
If I write:
% out.print(one); %
% out.print(two); %
then my reading of the spec says that I must get the two words printed on
different lines (which I believe Orion would do), whereas you seem to be
saying that Sun's RI would print onetwo. Or is Sun's RI somehow clever
enough to know the difference between my sample and yours? That would take
some clever examination of what's in the scriptlets, I would think.

Orion should eat that newline. This is how other JSP engines behave,

It shouldn't break the java code by inserting an erroneous println...

Hi Adam,
I don't think this is a bug, although I agree the messages are
confusing. Set the development=true flag in the orion-web.xml and you
get the reason explained more fully. Basically what you have written in
the broken version produces code like this:
switch(1){
// write a new line (but can't be reached!)
case 1:
// write newline, One, newline
break;
// write a new line (but can't be reached!)
default:
// write newline, Default, newline
break;

RE: problem in accessing ejb from a bean in web-inf/classes direc tory .
These should be in the WEB-INF directory.
If you have your application packaged as WAR file it should have a folder
called WEB-INF. Your web.xml file should be there.
If you're running your code using orion's default web app, you'll find the
file under orion/default-web-app/WEB-INF.
In your web.xml file the ejb references should be defined like so:
ejb-ref
ejb-ref-nameejb/EDMSessionBean/ejb-ref-name
ejb-ref-typeSession/ejb-ref-type
homeCore.BusinessObjects.EDMSession.EDMSessionHome/home
remoteCore.BusinessObjects.EDMSession.EDMSessionRemote/remote
ejb-linkTheEDMSessionBean/ejb-link
/ejb-ref
With this definition my code would then expect to find the bean under
java:comp/env/ejb/EDMSessionBean
In you orion-web.xml, which should reside in you application-deployments
directory, you need to link the bean like this:
ejb-ref-mapping name="ejb/EDMSessionBean" location="TheEDMSessionBean" /
In this case location="TheEDMSessionBean" is the location specified in your
ejb-jar.
Hope this helps.

RE: JAXP
The other day, somebody posted a well written document on Java2 class loaders. I wish I had the url to the document, but I can't find it. The gist of the document was this: All class loaders within a jvm form a hierarchy with the boot class loader being at the root. No matter which class loader in this hierarchy is utilized, it's job is to always delegate to it's parent class loader before attempting to load anything on it's own. In this case I belive orion's application class loaders will still be children of orion's class loader, so classes defined at the class path level (using orion.jar's classpath manifest attribute) will be used. Even if you create a lib entry to jaxp in server.xml or orion-application.xml the jxap that ships with orion will be used.

This idea comes from the fact that every class is identified not only its class name but also which class loader it is loaded from. Since Orion supports dynamic loading of application files, it should be using a custom classloader for every application. Hence, by theory, you should be able to use a different JAXP than the one Orion uses. Of course it depends on exactly how Orion implements this.

It appears to me that Sun's RI is recognizing the obvious - that statements
can not appear between switch and case, nor between break and case.
Unless the spec specifically addresses this, it seems that Orion is doing the
correct thing, and Sun is providing a nicety that lulls one into writing bad
JSP code.
tim.
Sorry if I didn't quite get your point.
It's odd though. The spec VERY specifically says that whitespace must be
preserved (JSP 1.1 spec, section 2.1.6), so it seems to me that what Orion
is doing is correct, even if it seems inconvenient.
If I write:
% out.print(one); %
% out.print(two); %
then my reading of the spec says that I must get the two words printed on
different lines (which I believe Orion would do), whereas you seem to be
saying that Sun's RI would print onetwo. Or is Sun's RI somehow clever
enough to know the difference between my sample and yours? That would take
some clever examination of what's in the scriptlets, I would think.

Hi Adam,
I don't think this is a bug, although I agree the messages are
confusing. Set the development=true flag in the orion-web.xml and you
get the reason explained more fully. Basically what you have written in
the broken version produces code like this:
switch(1){
// write a new line (but can't be reached!)
case 1:
// write newline, One, newline
break;
// write a new line (but can't be reached!)
default:
// write newline, Default, newline
break;

and the compiler complains (correctly) that some of the copde can't be

In Orion, are tag handler instances reused or reinstantiated?
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.

Of course, you can download the already integrated version, but you'd be getting an old JBoss and an old Tomcat... The main problem with Tomcat and JBoss is also their virtue. Since everything is so modular, it also means that there are a lot of components, some of which have conflicts among eath other Among other things, JBoss is not compliant to any spec, as simple things like java:/comp/env namespace are plainly not supported by their jndi impl, cmp (jaws) support is very poor and does not really scale well to more than a couple kids playing "deploy" on 3 machines... JBoss also has many problems deploying j2ee "ear" (Enterprise Archives) ... Although Orion is small, it's self-contained and requires very little work to get everything running. flame-warning I respect the authors of JBoss as they have done a great job, but you really can't compare... it's a orange vs. apples comparison.

Most of the ASF is trying to stay compatible with dead things (jdk 1.1), which makes their software suffer a great deal. For example, they dislike the use of the Collections API, try to solve everyone's problems for everyone, and in the way bloat their products unnecessarily... And repeatedly "break" the rules...

It's rather sad, as most of those problems could easily be solved... Sometimes people on the list say things like "I can't get Cocoon to work under Orion", "I can't get XXX Apache product to work under Orion"... well now you know why :) haha ...

Ok,
there is no superclass since InitialContextFactory is an interface which is
implemented
by ApplicationClientInitialContextFactory directly (so every vendor provides
his
own InitialContextFactoryClass...)
Can you show that part of your code? Perhaps you can do smthng like this:
// Perhaps this one is read from a configuration somehow
String factoryClassName =
"com.evermind.server.ApplicationClientInitialContextFactory";
InitialContextFactory factory;
try {
Class c = Class.forName(factoryClassName);
} catch (Throwable t) {
System.err.println("Unable to load initial context factory " + factoryClassName
".");
t.printStackTrace();
}
It should work like this: when the class is needed it should be loaded by
the class
loader over the net (this is a basic principle of JNDI: load the "driver"
which is
needed for current application, if not already installed on the client).
Well, perhaps you're referencing the driver from your code, and perhaps you
should try loading the class explicitly with the Class.forName() call?

Servlet Filters
Hi, We're currently trying to move our web site from running IIS to hopefully Orion and we've come across something in the servlet container that we're hoping someone has seen or dealt with themselves before. We want to use a servlet filter to intercept *all* requests that come into the web server. Is this possible? It seems to work for all files when I put the URL filter as "/" or "/*". But we're also looking to be notified when a directory resource is requested. An example of this might be a url that looks like so: "http://www.somecompany.com/test". Test is not a virtual directory nor is it a directory under our site root. We forward these directory requests to a JSP that then produces the appropriate output for this directory on the fly. Has anyone tried this? Or is there another way to filter HTTP requests in the Orion web server? Thanks! -Mike

Re: mail.jar POP3
If you upgrade the mail.jar to JavaMail 1.2, the POP3 provider is included. Replacing mail.jar is most likely your easiest route. Otherwise, you have to deal with the javamail.providers file, which will almost certainly require that you modify mail.jar's version of that file. tim. Hello, I'm trying to add POP3 functionality to my application on orion. Unfortunately, the mail.jar that ships with orion does not include the POP3 provider. Does anyone know how I can enable the POP3 provider from Sun without replacing, or otherwise having to modify the existing mail.jar? Thanks, Andre Machines should work. People should think. -- IBM motto

login security include file
I'm trying to do a response.sendRedirect() from an include file jsp:include and wanted to avoid doing a directive.include (preparser), I keep getting "Response has already been committed, be sure not to write to the OutputStream or to trigger a commit due to any other action before calling this method." I have been very careful as to put this include at the very top of the file, and to specify autoFlush=false and flush=false on the include tag. Again, the intention of this include file would be to be place at the top of the jsp file to secure it by redirecting to a login page if credentials in a session based UserBean do not allow access to the page for some reason. -Vaskin

However, I could not make Orion as EJB server work with Apache Tomcat.
A servlet is placed to access ejb at tomcat's WEB-INF/classes directory,

HelloHome.class);
}
catch (Throwable exception) {
throw new ServletException(
"Unable to get home interface: " + exception.toString());
}
// Get a reference to a Hello instance
try {
_hello = helloHome.create();
}
catch (Throwable exception) {
throw new ServletException(
"Unable to create Hello instance: " + exception.toString());
}
// Insanity check: Make sure we have a valid reference
if (_hello == null) {
throw new ServletException(
"Unable to create Hello instance, create() returned null");
}
}
// Handles the HTTP GET request
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
trace("doGet");
ServletOutputStream out = response.getOutputStream();
response.setContentType("text/html");
// Get the answer from the bean
String answer;
try {
answer = _hello.sayHello();

RE: Servlet Filters
We want to use a servlet filter to intercept *all* requests that come into the web server. Is this possible? It seems to work for all files when I put the URL filter as "/" or "/*". But we're also looking to be notified when a directory resource is requested. An example of this might be a url that looks like so: "http://www.somecompany.com/test". Test is not a virtual directory nor is it a directory under our site root. We forward these directory requests to a JSP that then produces the appropriate output for this directory on the fly. Has anyone tried this? Or is there another way to filter HTTP requests in the Orion web server? Given that you seem to have worked out how to intercept /*, intercepting /test/* is a simple extension of that. Presumably you have something like this in your web.xml servlet-mapping servlet-nameWhereStuffGoesByDefault/servlet-name url-pattern/*/url-pattern /servlet-mapping So for /test/* you'd have servlet-mapping servlet-nameTestServlet/servlet-name url-pattern/test/*/url-pattern /servlet-mapping The problem is working out which order they're considered. I imagine it's probably the order they're specified, so you'd want the test one listed first in your web.xml. I'm assuming that by intercepting all requests you want everything (except test/*) to go to a particular servlet. If you just mean intercept and feed back whatever resource they asked for, then all you need is the second code snippet in your web.xml Trond.
Re: orion.jar needed for JNDI-lookup??
Stefan, Are you sure about the InitialContext class being loaded over the network? I have never heard of that before, and was not aware that JNDI supported this feature. Can you point to any documentation of the feature? I have always understood that the JNDI properties pointed to the class to be used, and that the class had to be accessible via the ClasPath. thanks, tim. Hi Ernst, there is no superclass since InitialContextFactory is an interface which is implemented by ApplicationClientInitialContextFactory directly (so every vendor provides his own InitialContextFactoryClass...) It should work like this: when the class is needed it should be loaded by the class loader over the net (this is a basic principle of JNDI: load the "driver" which is needed for current application, if not already installed on the client). To be more specific with my error: I get an error from the java.net.URLClassLoader which says he(she...?) can't find the specific class (ClassNotFoundException). Did I miss some setup somewhere ... ?

Subject: RE: I switch from X to Orion because:
Just a few comments...not angry comments. :-)
As a committer on an Apache project, let me just say that decisions to
support JDK 1.1, on a per-project basis, are not about
supporting "dead
things". We have, in fact, people who _must_ use JDK 1.1
(probably more than
you might think). As another example, we are a J2EE shop; but
just recently
we had a (big) requirement to support ISAM data. That's
ancient, too, but
I'll bet there's more ISAM data out there than there is
relational data.
Would you personally turn up your nose at supporting ISAM?
Well, maybe you
would. I dunno.
I also use ISAM data, talk to mainframes (MVS, OS/390, VSE) and minis
but we are not talking about that. We are talking about Apache neglecting
important features in newer versions of the jdk which would work with all
versions of the jdk. for example, instead of producing code with 200
occurences of:
Class clazz=Class.forName("blabla");
these could be replaced with:
Class clazz=ClassUtils.findClass("blabla");
where you could have a "central" ClassUtils with a static method called
findClass which would find the class in the correct classloader
(contextclassloader or primordial, etc)... The only drawback to this
approach is that although the resulting code would work with any jdk, it
would need jdk1.2+ to compile, but of course there are workarounds around
this... So just becuase there are few jdk1.1 users out there, Apache
releases code which will not work in advanced containers and require severe
patching. (e.g. ever tried to use Xalan, BSF or Xerces together in JBoss,
Resin, Orion?)
I haven't used Struts myself, but since you mention it, I'd
guess you'd have
to ask Rickard himself why he decided to write his own
framework. With all
due respect to him, the primary reason, 9 times out of 10,
that people write
their own code is because as an industry we are damned
terrible at re-use.
There are a whole bunch of bad reasons why this is so -
laziness, arrogance,
reluctance to share the limelight, etc etc. Only rarely do
you find that
somebody wrote code because they conducted a thorough search
and couldn't
find anything that could even be modified. I'm personally
pretty hot about
this topic because there is a huge amount of wasted time due to this.
Frameworks are a particularly bad offender - everybody and
his brother wants
to write their own framework.
quoting from Webwork documentation...
"Q: What is the difference between WebWork and Struts?
A: Struts is probably the technique that was the most similar to WebWork.
The main problem with Struts is its large API. There is quite a bit of API
to learn, and it is closely tied to Servlet API. The Struts API also imposes
quite a few implementation rules with regard to how things are done, leaving
less room for customization.
"
(Large API == Bloated?) since both do the same things in concept.
This industry is very pro-reuse, it's only when projects become surreal,
when people start building something else. Let's get real, would you spent
your time building something when there is another product which is
accesible and fits your needs entirely... ? thought not...
The problem here is that you can't serve god and devil at the same time.
As far as bloat, well, that's in the eye of the beholder. If a product
provides 100 features, but any given user only needs 25 of
them, but nearly
all of the features are useful to someone, it's "bloat" to
almost everyone,
but also useful to almost everyone. It's only bad bloat if the extra
features get in your way, though, when you want to use your subset. I
question whether this happens that often. But most of your
comments are
pretty general, so who knows exactly what you were talking about.
Usually I don't mind about extra features, but take Xerces for example...
it's a 800k jar file compressed, provides for just about every xml parsing
scheme that currently exists, has a built-in serialization API, XML DOM,
HTML DOM, you name it, it's there It is also the most popular xml parser
for java right now... what's the problem? it's also the worst performant out
of the xml parsers for java... So strictly my opinion, why not spend
precious time trying to improve the things which are really important (speed
and basic conformance) instead of trying to build a do-it-all-for-everyone
parser. Then people say, "Why is java slow?" Is Apache becoming the
Microsoft of the open source arena?
Are Apache products perfect? No, not by a long shot. Are they
as bad as you
make them out to be? No, not by a long shot.
Perfection cannot be attained, it can be aspired... The problem is that you
can't aspire perfection without criticism. And Apache hates

Subject: RE: I switch from X to Orion because:
Just a few comments...not angry comments. :-)
As a committer on an Apache project, let me just say that decisions to
support JDK 1.1, on a per-project basis, are not about
supporting "dead
things". We have, in fact, people who _must_ use JDK 1.1
(probably more than
you might think). As another example, we are a J2EE shop; but
just recently
we had a (big) requirement to support ISAM data. That's
ancient, too, but
I'll bet there's more ISAM data out there than there is
relational data.
Would you personally turn up your nose at supporting ISAM?
Well, maybe you
would. I dunno.
I also use ISAM data, talk to mainframes (MVS, OS/390, VSE) and minis
but we are not talking about that. We are talking about Apache neglecting
important features in newer versions of the jdk which would work with all
versions of the jdk. for example, instead of producing code with 200
occurences of:
Class clazz=Class.forName("blabla");
these could be replaced with:
Class clazz=ClassUtils.findClass("blabla");
where you could have a "central" ClassUtils with a static method called
findClass which would find the class in the correct classloader
(contextclassloader or primordial, etc)... The only drawback to this
approach is that although the resulting code would work with any jdk, it
would need jdk1.2+ to compile, but of course there are workarounds around
this... So just becuase there are few jdk1.1 users out there, Apache
releases code which will not work in advanced containers and
require severe
patching. (e.g. ever tried to use Xalan, BSF or Xerces together in JBoss,
Resin, Orion?)
I haven't used Struts myself, but since you mention it, I'd
guess you'd have
to ask Rickard himself why he decided to write his own
framework. With all
due respect to him, the primary reason, 9 times out of 10,
that people write
their own code is because as an industry we are damned
terrible at re-use.
There are a whole bunch of bad reasons why this is so -
laziness, arrogance,
reluctance to share the limelight, etc etc. Only rarely do
you find that
somebody wrote code because they conducted a thorough search
and couldn't
find anything that could even be modified. I'm personally
pretty hot about
this topic because there is a huge amount of wasted time due to this.
Frameworks are a particularly bad offender - everybody and
his brother wants
to write their own framework.
quoting from Webwork documentation...
"Q: What is the difference between WebWork and Struts?
A: Struts is probably the technique that was the most similar to WebWork.
The main problem with Struts is its large API. There is quite a bit of API
to learn, and it is closely tied to Servlet API. The Struts API
also imposes
quite a few implementation rules with regard to how things are
done, leaving
less room for customization.
"
(Large API == Bloated?) since both do the same things in concept.
This industry is very pro-reuse, it's only when projects become surreal,
when people start building something else. Let's get real, would you spent
your time building something when there is another product which is
accesible and fits your needs entirely... ? thought not...
The problem here is that you can't serve god and devil at the same time.
As far as bloat, well, that's in the eye of the beholder. If a product
provides 100 features, but any given user only needs 25 of
them, but nearly
all of the features are useful to someone, it's "bloat" to
almost everyone,
but also useful to almost everyone. It's only bad bloat if the extra
features get in your way, though, when you want to use your subset. I
question whether this happens that often. But most of your
comments are
pretty general, so who knows exactly what you were talking about.
Usually I don't mind about extra features, but take

Re: Orion with tomcat!!!
I know it has been mentioned in serveral times. However, I could not make Orion as EJB server work with Apache Tomcat. A servlet is placed to access ejb at tomcat's WEB-INF/classes directory, along with application-client.xml under META-INF directory. That's strange. I've built two different applications, both using Orion as an app server and Tomcat and Resin as servlet containers, both with Apache as a web server. In both application i had no ejb references in the web.xml and i have absolutely no application-client.xml. I've just built war files with the required lib, classes, jsps and servlets... few parameters into the web.xml and that's it. It looks from your stack trace that the problem is that the application cannot connect to the application server at all... I'm afraid that you're using the wrong port this unless you have changed the port number in the rmi.xml file from the default (23791) to the one you've set in the environment for the intial context (800).

Struts (was: I switch from X to Orion because: )
This subject is especially timely for me because I just finished evaluating both WebWork and Struts. I decided to go with WebWork. It wasn't so much that I was drawn to WebWork's technological coolness - there are some neat ideas there, but I think most could be adapted into Struts with a little effort. The problem was that when I looked deeply into Struts, I didn't like what I saw. I spent a *lot* of time wavering; on one hand, Struts has a solid user community and good javadocs, on the other hand, WebWork is simpler and easier to teach future members of the team. I kept switching my favor back and forth when I discovered something new I did or didn't like. What finally pushed me over the edge was my experience hunting down the problem preventing Struts from working with Orion out of the box. Here's the story: If you've ever tried loading the Struts 1.0 example app, you are immediately confounded by missing resource errors. There is a lot of complaint in the Orion and Struts archives about this, but the closest anyone has come to nailing it down is this message: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg00582.html in which the principal author of Struts, Craig, implies that Orion's classloader has a problem preventing it from working with the standard JDK ResourceBundle. I knew there was something wrong with this because WebWork uses ResourceBundle without issue. So I looked through Struts' source to see how it might be using ResourceBundle differently, and what I discovered is that Struts doesn't use ResourceBundle at all! In fact, Struts has a whole homebrewed framework for handling properties which mirrors the ResourceBundle API but doesn't use any of its classes or interfaces. There are javadoc comments to the effect that the Struts code should be faster than ResourceBundles, but looking at the JDK 1.3 source code, both frameworks seem to be doing pretty much the same thing. For those curious, the actual problem with Orion is that Struts uses ClassLoader.getResourceAsStream() to build the Properties object, and (I checked the decompiled code) the Orion classloader does not implement getResourceAsStream(). Orion's fault, and logged as bug #340. But why re-invent the wheel?!? The JDK provides resource management for us! Even if the Struts code was slightly faster (which I doubt), any performance gain is going to be negligable compared to the amount of time spent processing taglibs, etc. I can't believe that whoever wrote the Struts MessageResources classes ever bothered to run the code through a profiler to find out where the real bottlenecks are. All this extra code and duplicated infrastructure is nothing but an opportunity for more bugs, IMHO. At this point I decided to go with WebWork. It is certainly not without issues as well, but I'm very happy with the results. And I am finding that in a framework this simple, fundamental changes are easy to make. I could elaborate on the differences between WebWork and Struts if anyone is really interested. If you're still writing JSP-centric applications, you *really* should look into an MVC framework.

RE: Database schema type mappings
You're thinking C++. In Java: A long is 8 bytes, always. An int is 4 bytes, always. The byte-orders are fixed independent of the hardware, too. Speaking of byte size, here's something I found amusing (and annoying): long millisInMonth = 1000 * 60 * 60 * 24 * 30; Date thirtyDaysAgo = new Date(); thirtyDaysAgo.setTime(thirtyDaysAgo.getTime() - millisInMonth); This actually produces a date in the FUTURE! It took me a while to hunt down this bug because it had really wierd effects on my application.

This sounds like you didn't set the transactional behavior in ejb-jar.xml as "required". There is no default behavior in the spec so it is up to the container to decide what the default behavior is. I know in Weblogic, transactions default to "supports" (I think). In any event, the entities are not stored in the database unless you mark them as "required".

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.
RE: Database schema type mappings
From: Randahl Fink Isaksen [mailto:[EMAIL PROTECTED]] 1. Why is Integers automatically converted to int by Orion - and is this a standard EJB convention? Yes. All the class representations of the primitive types should work that way. 2. Would it be legal to have a primary key of the primitive type "int" instead of Integer? No. Primary keys must be Objects. This makes sense because EntityContext.getPrimaryKey() returns an Object. Jeff
referring to a jar from an ejb-jar file/directory?
I have an ejb application running under orion. I want to restructure the code so that some common code is put into a jar. The problem is that I can't figure out a way, short of putting the jar in the orion/lib directory, to make the contents of the jar available to the ejb side of the application. The EJB-2.0-pfd spec says: The ejb-jar file must also contain, either by inclusion or by reference, the class files for all the classes and interfaces that each enterprise bean class and the remote and home interfaces depend on, except J2EE and J2SE classes. (page 486) Well, what does 'reference' mean? The only hint I have found is: An ejb-jar file does not have to physically include the class files if the classes are defined in another jar file that is named in the Class-Path attribute in the Manifest file of the referencing ejb-jar file or in the transitive closure of such Class-Path references. (page 487) Well, I'm going to try creating a manifest file with a Class-Path in it, but since I'm running out of a directory, not an actual ejb-jar file, I really doubt this is going to work! Any hints would be greatly appreciated... Gary
