Re: How to trap orion shutdown

Hi Vidur,
I don't know if this will help but Servlet.destroy() should be called
on shutdown of the web container.

Re: Classpath settings - Ver 1.1.30

Hi Todd,
Do you have an EAR file or directory structure? If you do, I would
put the jars in the

Hope this helps,

Hi,
I understand that orion has a UserManager that can be used instead

Is this similar to what Apache does if you set up access via the RDBMS

rather that the file based ones?
Which example uses this and can anyone give me more info about the

init-param is just for the JSP or servlet and accessed via

String ServletConfig.getInitParameter(String)
Enumeration ServletConfig.getInitParameterNames(String)

HttpServlet extends GenericServlet so you could use in a servlet
the methods from GenericServlet the method with the same signature as the
methods above.

These are in relation to this servlet only.

context-param is for the whole web application and is accessed via
String ServletContext.getInitParameter(String)
Enumeration ServletContext.getInitParameterNames(String)

this in JSP is the "application" implicit variable.

Let us know if this is correct.

The following stack traces shows that you client does not have a deployment 
descriptor. Even
application clients run in a J2EE container. In this case you need to supply the 
application-client.xml
file below.

It should contain the lookup info for the initial context you put in the following code
Hashtable h = new Hashtable();
h.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClientInitialContextFactory");
Context jndiContext = new InitialContext(h);

After you add the file then the above code could be replaced by

Context jndiContext = new InitialContext();

The DTD for application-client.xml  can be found at
http://java.sun.com/j2ee/dtds/application-client_1_2.dtd

Then to redeploy on another server just the XML file changes.

Hope this helps,

Eric :-)

Re: Performance & Scalability Concern

[Eric Richardson]

I see that, but that sets the policy of which libraries to use at the server
level. When you have a large codebase then pieces of it and the applications
may use different non-binary compatible versions and this breaks the component
model of J2EE. Except for the J2EE version, each app should be self reliant.
This is what I think anyway.

I agree, they have stepped outside the spec on this one but maybe the
spec
should be changed.  How does a container process the ejb-jar.xml
file if it
can't load a parser?  Hopefully, they don't have to write another
one just
to conform.  It's one of those gray areas I think.
At least I don't have to 'hack' the jar files and Orion has provided

IMHO this is a problem in Orion. As far an application is concerned,
they
should only be able
to see the J2EE classes. Somehow the class loader scheme needs to insulate
the
application
from the server classes. In this case XML is not part of the current

spec
and I'm hoping they won't add it. I haven't looked at an future specs

J2EE.

Re: Sessions And SSL

Hi,
I think you have to generate and load your cert and associated stuff via
the java tools. I did this
once on J2EE reference edition. ASelf generated and signed Cert will work
for testing.

If you want a real site you need to buy a certificate from VeriSign or some

You should pick a company that is pre installed in common browsers.

Re: admin -shutdown

[Eric Richardson]

Hi,
We are evaluating orion for an internal app and our overall opinion
is thumbs up.
1. it is really j2ee compliant
2. stable
3. good performance
4. not expensive
If you are using internal or selling there is a risk of course.
1. small company
2. not open source-you can't fix problems yourself(not too many opensource
alternatives)
The worst risk is that you might have to port your j2ee app to another
platform and this platform would be
1. more expensive
2. performance?
...
If the risks are discussed and documented then I think Orion is a great
bet regardless of the problems.
Also, the team is very responsive to fixing bugs and making the product
better-probably better if you are a customer.
FWIW,
Eric :-)

This issue is frustrating to me.  You'd think something as fundamental
as
shutting down the server would work--it did in 0.9.  I really
like Orion,
but I just can't recommend it to my employer if such fundamental features
don't work.  Ideally you won't be shutting down the server very
often,
however when you are configuring and testing you do it a lot. 
This issue
has received a lot of traffic on this list, but I have yet to hear
anyone
for the Orion Team explain either a) what we're doing wrong to cause
this
error, or b) that it is indeed a bug in the software and it will be

I understand Orion is hard to beat for the price, but I'd gladly pay

Hi Klaus,
If you are displaying a bunch of data on your page, agree with the
approach. Then if someone wants
to change the data, I would suggest having a separate edit page for
that data. In this case I would
use a entity bean directly behind the form.
Did you use CMP entity beans to make your display beans from the session
beans? This is how the pet store
does it. If you do then the entity bean for that row will already be
loaded so asking for it in your edit page
would not be expensive except for all the calls to display the attributes.
Hope this helps,

We use Resin and Orion for Web Apps by putting our files into an EAR
structure(from J2EE). This lets us have 1 line of configuration in two files in
Orion and only one small section in the Resin config file. The resin config
needs to point to the web directory inside the EAR which is expanded. We make
no changes to the app from one system to the other.

Re: PORTABILITY PROBLEMS !!!

[Eric Richardson]

Hi David and Karl,
I talked to the J2EE group at Java One about this exact subject and
just sent a message to the [EMAIL PROTECTED] group. I also cross
posted the previous post in this thread as support.
I think other people need to let the J2EE team know about these issues
and the importance for your apps. They can then coordinate with the EJB
and Web container teams on this issue. Hopefully an SPI can be developed
that both containers can use.
Funny how security always comes up last.
Eric :-)

Hello David,
Unfortunately there are still a few things that are not standardized
in J2EE
1.2, especially in the field of security and user management (like
dynamically
adding users to the server).
For such things, the application server vendor unfortunately has to
provide
their own ways of doing things, and some of our demo applications demonstrate
those features as well. We will try to push for as much as possible
to be
standardized for better portability, and it is happening. For example
OR-mapping was not standardized in EJB1.1 but is/will be in EJB 2.0
and we
have just converted our OR-mapping to match the EJB 2.0 draft (but
will not be
available publically just yet). Of course it'll take some time before
the spec
sorts out every portability issue though.

Hi Orion Team,
This problem is fixed in 1.0 Internal build 3

interface Product {}
interface Pet extends Product {}
class PetImpl implements Pet {

}
The use bean gets the product which is a PetImpl and properly deals
with it!!!

Re: useBean scope problemed

[Eric Richardson]

Hi Magnus,

I'm sorry I didn't respond earlier. We just found out yesterday afternoon that
the Iterate tag issue is not a problem. I didn't recompile it yet for the
three argument method setAttribute, but you said before that you fixed this.

Please close the other setAttribute report for 1.0 internal build 3. This is
not a problem, it just took us a long time to sort it out.

This current problem below confuses me a bit. The resulting code if it made it
thru the parse phase would compile but it doesn't make it thru the parse
phase. I couldn't find anything in the spec that would say this is not an okay
usage but couldn't find anything that says it's okay either.

The main goal in the code was to make the creation of the bean right where I
wanted it(readability, maintainability etc). The BluePrints state this type of
JSP controller is desired and actually they are easy to write and change so I
hope this is allowed.

Thanks for all the help,
Hope to see your team at JavaOne.

Eric :-)

p.s. I guess we may have to discuss this with the Sun Team. Do you want to
forward this message to them?

Taglibs/Orion Packaging

[Eric Richardson]

Hi,
Still trying to sort out my taglib problems. I'm not sure at this point
what classes I should compile
against. I thought the reference edition, j2ee.jar would make the most
sense. In theory each
server that licenses J2EE should use the same "interfaces" and basic
infrastructure classes. This way statics and other things would all be
the same.
Looking at orion, why are the "javax.jms" and "javax.servlet" packages
put into the orion.jar while all the other J2EE classes provided as separate
jars.
Could someone shed some light on this.
Thanks,
Eric :-)
 

Re: Source XML Error: External entity not found:

Hi Mark,

I have a problem like this in 10 Internal build 3. I have an application that
used a url  http://iron:8080/my.xml

on it and could not resolve the dtd. The application showed that it tried to
resolve it as
/local/app/orion/default-web-app/my.dtd rather than http://iron:8080/my.dtd

I'm sure this is just me not knowing how to configure orion and the XSLT
servlet but thought it might be helpful.

Tag lib fails with newest build

Hi,
We previously used an iterate tag lib but had problems with the three
argument setAttribute method so we hard coded to pageContext.
Code in tag library:
pageContext.setAttribute(name, iterator.next()); //page scope default

java.lang.InstantiationException: Could not find the bean named 'hierarchy'

Re: JSP Parsing Bug

[Eric Richardson]

Hi Anjana,
Good idea but I don't think this is the problem. I needed more info
like the previous message I posted on this subject.
The interface Product has the method getId().
The PetImpl class which is the actual bean on the page
implements Pet which extends Product. (a product taxonomy)
I believe the parser should use introspection to map id to a public
method getId().
It seems the parser is not following the inheritance chain.
The bean call is like this

It does work in Resin.
What is really cool thing is that the controller jsp can check product

It would also compile but the Orion parser prevents it from generating

Re: Look up a EJB from a JSP?

[Eric Richardson]

Hi,
The first two properties should be able to be put in a properties file such as
jndi.properties
usually on the classpath(maybe in the jre/lib directory). This can be read by
the system by the "InputStream Classloader.getResouceAsStream()" method. Orion
should allow for setting this for the system if it's not already loaded for
the client program. You should not have to write this code unless
you want the PROVIDER_URL to be dynamic and not from a property file.

The second two need to be set at runtime coming from the client program as
input.

Hope this helps,
Eric :-)

Re: JSPServlet not invoked for *.JSP

JSP useBean type problem

[Eric Richardson]

HI,
I think I've found a JSP parsing problem and would like confirmation.

Here is the situation for the classes:

interface Product {
  public String getId();
}

interface Pet extends Product {
  public double getWeight();
}

public class PetImpl implements Pet {

  public String getId();
  public double getWeight();
}

The page has a product of type Product in page scope. We use the
following tag
to get the correct casting of the PetImpl object.



Then we go to use it.

  


  

And get the following error.

-
500 Internal Server Error

Error parsing JSP page /pet_db.jsp line 59

Property 'id' in the 'com.ratex.common.Pet' type bean not found


If I comment out the first get:property then the page will compile and
run.

A Pet is a Product so I believe this may be a bit aggressive in the
parse phase. It works
on Resin FWIW.

Platform
Linux RedHat 6.1
Sun jdk1.2.2-001
Orion 1.0rc1

Any insights or help is appreciated.

Auto Deploy of web app from EAR?

[Eric Richardson]

Hi,
Isn't there some way that a web-app can be deployed by just reading
the application.xml file from the EAR?
Is it because the server can support multiple HTTP sites that the deployment
is ambiguous because it has to know which Web Container to deploy into
or is the problem more subtle?
It would be nice to not have to edit both the server.xml and the default-web-site.xml
file. I guess the
J2EE spoils us but it just deploys to the server directly but it can
be remote too.
Thanks,
Eric :-)

Re: Classloaders in orion

[Eric Richardson]

Hi Robert,

I have asked too about this because I also use XML and not the same version. I
use
xmltr2. My problem is that the parser is leaving whitespace between elements
where no whitespace can be according to the DTD. This breaks my code because
apparently I'm using the one built into the application server and it leaves
TEXT elements
between my elements. My workaround is to make sure my XML has no whitespace
between
elements.

In a previous post from Ken Saks on the J2EE team, he said in response to my
questions about
initial context:
from me
>> And then since components are loaded by seperate classloaders so they can
be
>> loaded and unloaded then what is the classloading scheme for the what I'm
calling
>> the "global" context or is there only one context?

from Ken
>It can be risky to make assumptions about the underlying classloading
>scheme used by an application server.  As a component developer the
>key is to obey the programming restrictions defined in the J2EE specs( e.g.
Runtime
>Environment chapter of EJB spec).   For example, the use of read/write static

>members in EJB components is discouraged.

Certainly, some restrictions and assumptions have to put in the J2EE spec.
What
if you want to use your own implementation as your point illustrates? What do
you
do?

My thought is that this is a very tough problem since the classloading scheme
is so
pervasive in the Java Platform. Sure the application server programmer can
provide their
own classloading scheme but usually there is a parent classloader and the
classloader must
look for classes somewhere when it has exhausted the local jar(s) for the WAR,

EJB Jar, or EAR. My understanding is that the classloaders differ to the
parent for
loading because it normally makes sense but in this case it seems it needs to
look
from local to global.

Some clarification would be very helpful,
Eric :-)

Re: Package private member access between JARs and WARs

[Eric Richardson]

Hi Gordon,
This code is valid. Both ctors and the setName method have default
access which
means they can be called by other classes in the same package. The
only thing
that's off limits is the private var.
So I agree and this is strange unless I'm missing something in the EJB
spec. Maybe
someone from Orion will comment.
Eric :-)

I'm having a problem with Orion that I don't get with
the Sun J2EE RI, regarding the use of package private members in one class
by another class in the same package (i.e. com.x.y) but in different JARs
or WARs.
Say that I have a value class in package com.x.y called
One as part of an EJB JAR:
package com.x.y;
class One
{
    private String name = null;
    void setName(String newName)
    {
    name = newName;

}
And a class in the same package com.x.y called Two as

package com.x.y;
class Two
{
    public Two()
    {
    One one =
new One();
    one.setName("Foo");
    }
}
These two classes are packaged in their respective EJB
JARs and WARs and deployed as an application.
In Orion, I get an IllegalAccessException on the "one.setName"
line, however other classes in the same EJB JAR as class One don't the
exception when the call setName.
The problem does not occur in the J2EE RI and I have not
found anything in the EJB/J2EE spec that would prohibit this cross-JAR
usage of package private members.
Any thoughts?
Thanks,

Re: Tag Example Problem

[Eric Richardson]

Hi Magnus,
I resolved my problem and think it is a bug. I did recompile with no
avail.
Karl wrote me back and suggested from now on if I found what I think
is a bug to copy it to [EMAIL PROTECTED] He said he would add that
to the Web site.
When this call is made in 0.9.6 the bean goes in application scope.
pageContext.setAttribute(name, iterator.next(), PageContext.PAGE_SCOPE);
I changed to the two arg version which for pageContext puts bean in
page scope which
solves the problem temporarily.
pageContext.setAttribute(name, iterator.next());
Thanks,
Eric :-)

Re: Tag Example Problem ***Possible bug***

[Eric Richardson]

Hi,
I found a workaround.
If in the doStartTag method I change
pageContext.setAttribute(name, iterator.next(), PageContext.PAGE_SCOPE);
to
pageContext.setAttribute(name, iterator.next());
Then the tag works on 0.96.
I checked it out and if I use PageContext.PAGE_SCOPE in the taglib I
can retrieve
it from application scope. So I think this is defined wrong and is
a bug.
Is [EMAIL PROTECTED] where bugs should be sent? Couldn't see anything
on Web Site.
Hope this helps,
Eric :-)

Re: problem with orionserevr and jdbc on win95

[Eric Richardson]

Hi LynchWu,

You should be able to just drop this oracle library in the orion/lib
directory.
Edit the datasources.xml as a shown in a previous post recently and then
it should work.

0.96 problems: Was Re: 0.94 and 0.96 problems

[Eric Richardson]

Hi Magnus,
Oops I miss stated earlier. To make my code work I have to remove all
whitespace out of the
xml document to make sure extra text nodes are not in the document
DOM.
Eric Richardson wrote:
Hi Magnus,
Well, I was using the autoupdate version of 0.96 and didn't know that
you released a real version yesterday.
I don't know what you did but now the XML parses correctly with the
version I use and the superclass classloading problem is fixed as well.

In my code I call doc.normalize() and use strict parsing according
to the DTD. When I ask for children, I get the nodes I expect with no #text
nodes between the elements.
It seems the classloader is following the chain somehow and using the
classes supplied by Orion. I put all my libs in WEB-INF/lib including the
xml.jar from the XML-tr2 package.
I can use Orion and ignore this for now but the classloading may be
a problem for others in the future as well.
Any help would be appreciated.

Wow! Thanks a bunch.

Subject: 0.94 and 0.96 problems
 Hi,
After three days of work to try and get Orion going for a simple example
using our infrastructure code, I give up.
Here are the details.
1. We use our own XML lib (xml-tr2) to get info from a config file.
This is used by our Persistence layer and connection pool etc.
2. I created a web app with web.xml and also tried it as a real j2ee
app with application.xml
Here are the problems with 0.94
1. Can't load a superclass that is clearly in the jar (stack trace below)
even though the JSP has sucessfully
loaded and instantiated two beans that work.
2. In a web application if classes are included from J2EE (even though
this was a mistake) it causes problems.
 
Here are the problems with 0.96
1. My XML config file is parsed with included white space which represents
extra Text Nodes. This caused my code not to work here. When all whitespace
is removed from the file my code works again.
Somehow this must not be using xml-tr2.
2. Then nothing happens and the JSP apparently just stops half way
through the service method.
 
I can only think of one thing-classloader problems. I am not an expert
but application code can't conflict with server code in this way. Otherwise
the system is brittle, libraries used are brittle and ...
To go to J2EE we can't redo everything so our code needs to co-exist
in the system. First, we could take advantage of the build in connection
pools and transactions, and then add EJB and eventually migrate all our
code base to the new architecture J2EE.
I also launched the vm using -verbose and it seems to load everything
until it gets to my scriptlet code. I looked at the generated JSP code
and that looked fine as well. The only thing that's a little different
in our code is that the Persistent class below is abstract. Our code works
in JRun, Resin, Tomcat and older versions of Orion.
Suggestions for Orion
1. Tracing controlled by the developer and other features to help the
users or Open Source.
2. Good luck because I think there must be alot of potential with this
server.
Sorry that I can't get any mileage out of it.

Re: ANY ONE USING ORACLE WITH ORION SERVER

[Eric Richardson]

Hi Sudhir,
Can't help you with this-this is security stuff with orion.

You can create a JSP using
your connection to Oracle to see if it is working. Add the following to your JSP.

<%
javax.naming.Context context = new javax.naming.InitialContext();
javax.sql.DataSource dataSource =
(javax.sql.DataSource) context.lookup("jdbc/OracleDS");
java.sql.Connection conn = dataSource.getConnection();
java.sql.Statement stmt = conn.createStatement();
java.sql.ResultSet rs = stmt.executeQuery("select table_name from user_tables");
while(rs.next()) {
 out.println(rs.getString(1));
}
%>

Help Needed 0.94 and EARs

[Eric Richardson]

Hi,
Do you have to have a separate enterprise application to run a web
app in WAR format
on this version of Orion?
Can you use the global-web-application.xml which points to application.xml(doctype
orion-application) or do you have to have application.xml(doctype application
from j2EE)?
Orion folks, do you settings from these "global" config files sort of
provide default setting for applications and web applications that don't
specify settings. are there some rule which can be published? Some of the
new documents help but as you change the server and config files, it's
hard to understand what we need
to know.
Thanks for any help,
Eric :-)

web app setup / classloading problem

[Eric Richardson]

Hi,
I'm trying to set up a web app without a enterprise app.
I copyed default-web-site.xml to eratex-web-site.xml and edited to
change the port. It looks like this minus the header.

 
 
 
   name="eratex"

root="/eratex"
   load-on-startup="true">
    
 
 

I added  to server.xml
I added to application.xml (document-type orion-application) the following
tag.
 and put
my app in WAR
layout but not zipped.
This is my web.xml in the WEB-INF dir.

  E-Ratex Web App
 
  Provides a complete shopping site.
 
  
    index.html
  
 
  
    product-demo.jsp
  
  
    Used to find the AppConfig configuration
file
    configFile
    WEB-INF/eratex.xml
    java.lang.String
  

Here are the problems:
1. doesn't find welcome file list when I put http://localhost/eratex
but will find it when I add index.html to the URL.
2. The server seems to find my beans on the JSP page from a JAR file
inside the WEB-INF/lib dir but when it comes to the scriplet code it fails
to load the superclass of Product.
Persistent <-- BaseProduct <-- Product
I check to see if Persistent is in the JAR and it is.
Here is the stack trace.

Can the java.lang.NoClassDefFoundError be called for a version problem
in my classes or is the server really not finding my class.
Any help would be really appreciated.

Re: Is CMP is useless?

[Eric Richardson]

Hi,
We also found the performance of Jonas poor for CMP. We currently are
using
a code generator for our persistence layer and even support of that
without hand coding
is a lot of work. we found CMP very handy but the mapping tools don't
give you the
flexibility of design that you'd have with an ODBMS.
I personally have not gotten Orion to work with EJB. I get stuck on
security for the examples
and I don't have endless time to mess around with it-I wish I could
see the performance you
got.
My question is about the isModified extension. From what I can see this
will work with
any container that supports it with out affecting containers that don't
support it. There was some code
posted (see below)I'm interested in and would like some comment. When
implementing
isModified on Jonas, each business method that changed the state of
your bean such as a set method would call setModified(true) thus the container
could call a method on your bean
boolean isModified() to check the state of the bean. Then the container
can avoid a call to the db.
The ejbStore and the ejbLoad methods have to be called according to
the spec but the container
version of these calls can be avoided.
Any comments?
What's going on in this code below?

I think your opinion on entity beans may be clouded by your use of Jonas
1.6.
We used Jonas in our project up until about 3 months ago. The entity
bean
performance in jonas is absoulutely terrible - their development team
admitted to it , something to do with RMI calls. The only way round
it at
that time was to do what you're doing and write a load of SQL code
in
session beans for handling collection stuff. This would be when iterating
over CMP collections would be too slow. In the end we had two lots
of code,
one slow that used entity bean calls( that we kept but didn't use)
and one
lot fast that used SQL calls.
Then someone mentioned Orion on the Jonas Mailing list, and that the
entity
bean performance was a lot better than Jonas. We tried Orion and got
it
working (eventually) and were blown away by its performance. In most
cases
the entity bean collection code in Orion would be FASTER than the SQL
session code in Jonas.
Fortunately we kept all the CMP code and we try to steer clear of SQL
statements in any type of EJB - as someone mentioned earlier its not
as
portable, but also the java compiler or Orion deployment tool will
always
catch table/column name errors and type errors where as hardcoded SQL
won't.
Just my 10 euros.

Re: Feature question

[Eric Richardson]

Hi Dale,
We have the same situation with a bunch of code, generator etc. I'm
planning on making my
stuff look like JNDI, DataSource etc. so my stuff can use resources
if they are available. These
are all interface specifications so if a datasource is available you
can use it if you are in Orion
other wise in JRun you would use your implementations.
Does this make sense? Please let me know if you make progress.

which I know are EJB things but I am wondering if it will stop me from

Re: Dynamic class loading in servlet

[Eric Richardson]

Hi Ted,

Very nice article.

I didn't understand the fine points of this but thought if my user class was
loading a class it should load in the same class loader as loaded my original
class. But apparently it depends on who loaded my original class. All my
classes were managed by Orion.

In JRun it worked fine as
Class.forName("package.class")

In Orion we had change the above since it didn't work-we used the
Beans.instantiate version of
this as I understand it.
Class.forName("package.class", true, this.getClass().getClassLoader())

Does this indicate a problem with Orion's Classloading scheme?

Hi,
Here is a little doc I put together that shows the ear layout with some

When I autodeployed an app into Orion, it inserted the file as you asked but I
had no luck getting any of the J2EE or the Orion EJB examples to work. All the
examples deployed but the orion one didn't let me past a security error which I
posted previously and I didn't even try to get the J2EE stuff to work since I
couldn't get the Orion EJB examples to work.

I general, I have seen no posts that have helped me get the EJB stuff working.
My thought is that if anybody does have it working, they aren't telling.
Probably because it's involved and if you don't know the specs by
heart-especially the xml deployment descriptors, it's hard to do. IMHO

Hope the doc helps you anyway,

Title: J2EE EAR File Structure






Overview

The Enterprise Application Archive (EAR) file is the only file needed to
deploy a J2EE application. It contains all the Enterprise Java Beans (EJB)
JAR files and the Web Application Archive (WAR) files. It also contains
all the Extensible Markup Language (XML) deployment descriptors and other
XML files needed for deployment. The J2EE application server can insert
it's own files as needed that are not part of the J2EE specification.


File structure

The following shows the files in an EAR for the ProductApp released
with the reference edition of J2EE. It has Container Managed Persistance (CMP)
but no web component or client application. These will be shown later in
this document.


ProductApp.ear

ejb-jar1813.jar
META-INF

MANIFEST.MF
application.xml
sun-j2ee-ri.xml




The contents of the MANIFEST.MF files contain no special information. The
following is the content of application.xml file.







  ProductApp
  Application description
  
ejb-jar1813.jar
  



Each server may have server specific configuration file. Follow the
following link to look at the 
sun-j2ee-ri.xml file.
Now we will look at the structure of ejb-jar1813.jar.


ejb-jar1813.jar

ProductHome.class

Re: Dynamic class loading in servlet

[Eric Richardson]

Hi,
Did you try Beans.instantiate(this.getClass().getClassLoader(),
"my.package.Classname") ? This would use the same classloader as servlet was
loaded in assuming "this" is the servlet? We had to do this going from JRun
to Orion and this is a much
better way for Servlet 2.2 API.

Re: Orion bug for disallowed-field with Oracle

[Eric Richardson]

Hi,
I mentioned this table name too long for oracle thing in a previous post as
well.

Another thing I don't understand is the need for xml document to map
java types to sql column types for specific DBs. DatabaseMetaData and
ResultSetMeta data
gives the types when looking at an existing DB and java.sql.Types gives you
the
standard type mapping from java to sql. It is the drivers responsibility to
make the mapping
to the database specific column names if they are not ANSI SQL. A good example

for Oracle is that if you specify thru JDBC to create a VARCHAR column the
driver
makes this VARCHAR2(oracle specific) in the database.

To be fair, there are some things that can't be done cross platform and these
specific
things need to be kept somewhere.

Jonas' http://www.bullsoft.com/ejb does CMP without these type mapping files.

Re: Problem running ejbsamples

[Eric Richardson]

Hi Karl,

First I'd like to say that I think you are doing a very good job in
general. We've
been experimenting with some apps running Servlet/JSP with very good
results.
We are really interested in getting EJBs running so we can see the
performance of
in particular CMP.  Thinking that the performance should be good since
everything
is running in the same VM.

I included a previous post below. We have alot of installed JSP
and they use the setProperty="*" as below. Is there any reason this doesn't
work? Is it a bug
or left out?

About documentation, the EJB demo is well documented. I followed all the
instructions
and I still can't get the CartClient to run. Below is the error. For me,
the configuration files are
very confusing. This is because I'm having a hard time figuring out which
are related to
the server and which are just the ones required in an enterprise app.

Example: A server can have multiple Web sites which can have multiple
applications. Then
the server should just have config for it and each web-site should just
have configuration
for that site. Also server specific config files(non-J2EE) should be easy
to differentiate such as the
orion-application.xml. Here is the structure I have in my head.

config - all server files

site-1 - all site related files including apps running in that site
site-2 - same as above

Now this doesn't make since if the same app is run in multiple sites.

Anyway,
Hope this helps.
Eric

Re: Problem running ejbsamples

[Eric Richardson]

Hi Vlad,
The auto deployment compile the beans and creates the wrapper code for the
beans. In addition
it tries to create the associated Database tables. You need a datasource. I
just plugged my
stuff in for Oracle. The first and the last four items are all that I
changed.

from data-sources.xml. I cloned the example and made this entry.

I had a couple of problems due to table name length- previous post but at
least it deployed.
That's all I know.
Eric :-)
p.s. good luck

Subject:  Ann: Orion Application Server 0.9.0 released with full
J2EE
  support
Content-Type: text/plain; charset="iso-8859-1"

We are proud to announce the availability of Orion 0.9.0.

This version provides an implementation of the full Java 2 Enterprise
Edition specification. This makes it the first commercially available
full
implementation of the J2EE specification.

Although we have yet to agree with Sun Microsystems on the terms of J2EE

licensing so we can not call it J2EE compliant and this is one of the
reasons for us not calling it Orion 1.0.

Except for this the new version also includes many bugfixes and
performance
enhancements as well as new features:

* Complex OR-mappings for CMP Entity beans (including Collection, Set,
List,
Map mappings)
* Automatic deployment of Enterprise application archives (.ear files)
and
application hotswap.
* Simplified SSL configuration and native SSL support with
certificate-based
client authorization.
* Simplified XML configuration file formats.
* HTTP tunneling for RMI (for firewalls)

As of now it is available for download and purchase.

You can download a full version at http://www.orionserver.com

Orion/0.9.1g initialized
The problem is that the table name   com_evermind_ejb_EJBUser_groups
is too long (31 characters) for Oracle .
Resolution is to edit the demo/ejb/usermanager/orion/orion-ejb-jar.xml
file.
added the table attribute as follows:
    The next is that I can't run the client. The instructions are not quite
correct. The classpath should be ../../../ejb.jar etc instead of ../../ejb.jar
and could use a :. for unix to find the CartClient.
This is the output:
 java -classpath ../../../orion.jar:../../../ejb.jar:../../../jndi.jar:.
CartClient
Communication error: Lookup error: java.lang.SecurityException: Invalid
username/password
Any help on the security issue would be appreciated. BTW, I did modify
principles.xml as specified.
Thanks,
Eric
