RE: Help me please domain was nul message is killing me here...
Ray, the problem is quite simple. I have two Orion servers. One server is running an EJB application model, the other server is running JSP client application. From the JSP server, I try to access the EJB server, by creating an InitialContext with the same parameters that I would if I was trying to connect to the EJB application using a standalone client (appplication-client.xml and ApplicationClientInitialContextFactory). At this point, I get a NullPointerException on the Client (JSP Server) side telling me that the "domain was null". The exact same code, works correctly when running as a standalone application, however, when put into the JSP Server, produces this exception. Some people suggested using ApplictionInitialContextFactory, however, since ApplicationInitialContextFactory reads application.xml, I have no place to put my ejb-ref tags to reference the objects in the EJB application. Other people suggested playing around with rmi.xml. This, however, hardly seems standard. I am trying to write code that is J2EE compliant without having to use any of the Orion specific features. So I am at a standstill. It's hard to believe that no one ran into this problem. In many cases it does not make sense to deploy the client and server on the same physical machine. Our JSP clients are running on the public internet while our EJB models are running on the private internet not accessible from the outside. Also, since we have many clients, we anticipate having a "farm" of EJB servers running the model, and a "farm" of JSP servers accessing this model. I am amazed that no one has stumbled onto this problem. If you have two Orion servers running, put the following code on one of the servers: Properties p = new Properties(); p.setProperty(Context.PROVIDER_URL, "ormi://target-host/application-name"); p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory"); p.setProperty(Context.SECURITY_PRINCIPAL, "user"); p.setProperty(Context.SECURITY_CREDENTIALS, "password"); InitialContext ctx = new InitialContext(p); You will need to replace target-host, application-name, user and password with values for your system. You will need to put the application-client.xml in to the proper directory. For a web application, this file should go into WEB-INF/classes/META-INF/application-client.xml. -AP_ -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ray Harrison Sent: Monday, April 02, 2001 8:16 PM To: Orion-Interest Subject: Re: Help me please "domain was nul" message is killing me here...

Re: usebean tag
Dear Alessandro,
the problem is in the page where I use the tag. I miss that value just
there and I save the dipartimentoQuery in the session. The mai problem is
with the jsp:setProperty tag. It saves string values, but losts Integers!
You're Italian, aren't you? I'm from Cosenza...

This is the code:
jsp:useBean id="dipartimentoQuery"
class="it.unical.amministrazione.np.DipartimentoQuery" /
jsp:setProperty name="dipartimentoQuery" property="*" /
In my jsp page this code would take the values from a previous form and
take them in my bean, but I lost the Integer value idUniversita (it was
in
a select tag). So I had to take it by a
request.getParameer("idUniversita")... Is this an Orion bug, is this a
Nicola's bug? Too strange!
Thanks in advance...
Nicola,
When you use the jsp:useBean tag with that syntax, you are inserting
that
bean in the page scope. Once the page is completed, that scope will be
cleaned up and your bean will be lost, so, if in a previous page you have
set the idUniversita member, it will be lost. Try inserting that bean in
the session scope, for example, so it will be accessible to the next page
and you will not use that value.

Kazuma

Internal Server Error
Hi, We're testing our web project (JSPs, Servlets and MS SQL 2000 DB). Orion app server version is v1.4.0. The test tool is MSWeb Application Stress v1.1. It's cool and free anyway, take a look: http://webtool.rte.microsoft.com/ The problem is minor, but it would be nice to clarify. During a 10 hour reliability test, some error appears, but only for POST methods. (The testing is replaying a recorded "browsing" by sending the POST and GET requests to the server, so it's like an average user, just no delay between the requests. FYI: Number of hits: 10798682 Requests per Second: 299.88, so it's quite busy). We have two problematic POSTs: Problem#1: URI: POST /login?action=dologout Hit Count:42018 Result Codes Code Description Count -- 200 OK42001 500 Internal Server Error 17 Problem#2: URI: POST /login?action=login-frommain Hit Count:42018 Result Codes Code Description Count -- 200 OK42010 500 Internal Server Error 8 What is interesting that there are no other POSTs in the test, just GETs, so it's somehow seems to be related to the type of the request. We're doing heavy logs during the test using log4j, so we have the complete log in a file. There is no detected problem in the log. The possible System.outs from Orion are lost, since the window it's running has only 999 line buffer. As you probably noticed, these POST methods are going to a servlet, mapped to /login. Other mappings are used of course, so the problem is not related to servlet mapping. Unfortunately I don't know when those logs coming (at once or in random intervals) My questions: - how to store orion logs? - any ideas what is this problem? - is there any way to catch these kind of errors? Any help would be very nice. Thank you in advance, Adam
Problem with @ character submitted in POST request through CGIServlet, TunnelServlet
There's a bug in the CGI servlet. What happens is: I have an HTML form which is transmitted via POST request. Two parameters are passed: email and action what should arrive is: email=peterb%40sbox.tugraz.at action=Login When perl gets the request the second parameter is truncated [EMAIL PROTECTED] action=Log This happens only if the first parameter contains the "@" character. I suppose the same bug affects the TunnelServlet too. I already informed Orion support about that some time ago, but didn't get a response, and 1.4.7 still doesn't correct this issue. For us this trivial bug is absolutely critical because we need to have orion handle requests and SSL in the front. Certain apps (the IMP PHP webmail) should be tunneled to apache, which still doesn't work! Other URL-encoded characters don't seem to have a negative effect, but the "@" causes the problem with the following parameter. I read on the list that also others have had problems with the Tunnel Servlet and POST requests. Maybe we can track down the bug a bit deeper. I entered it in Bugzilla as Bug Nr. 387 and hope that it finally will be taken care of. Regards, Peter

Microsoft replaces standard 404 'can not find page' errors with their own page, which is considered (by them) to be more user friendly. Still I do not understand how the Explorer gets the information there is a 404 error. Could this be somewhat less wanted feature of Orion?

Shared session
I'm kind of stuck on this one, been experimenting all this morning :) What I want to do is to share a session between several applications. Preferredly, I'd like to share the objects between those applications and the code. I want to use virtualhosts, and I confed my hosts file like this 127.0.0.1 company.localhost 127.0.0.1 admin.company.localhost 127.0.0.1 subdomain1.company.localhost 127.0.0.1 subdomain2.company.localhost The mapping to those work. But how do I access a session created in company.localhost at subdomain1.company.localhost? Is it possible or impossible? Can I create a "parent" application which handles the sessions and how do I configure it? And for sharing code, I'd like to have a single point of distribution, is there a way to tell in the web.xml where the classes dir is? Thanks in advance Johan Fredriksson

Ray, the problem is quite simple. I have two Orion servers. One server is running an EJB application model, the other server is running JSP client application. From the JSP server, I try to access the EJB server, by creating an InitialContext with the same parameters that I would if I was trying to connect to the EJB application using a standalone client (appplication-client.xml and ApplicationClientInitialContextFactory). At this point, I get a NullPointerException on the Client (JSP Server) side telling me that the "domain was null". The exact same code, works correctly when running as a standalone application, however, when put into the JSP Server, produces this exception. Some people suggested using ApplictionInitialContextFactory, however, since ApplicationInitialContextFactory reads application.xml, I have no place to put my ejb-ref tags to reference the objects in the EJB application. Other people suggested playing around with rmi.xml. This, however, hardly seems standard. I am trying to write code that is J2EE compliant without having to use any of the Orion specific features. So I am at a standstill. It's hard to believe that no one ran into this problem. In many cases it does not make sense to deploy the client and server on the same physical machine. Our JSP clients are running on the public internet while our EJB models are running on the private internet not accessible from the outside. Also, since we have many clients, we anticipate having a "farm" of EJB servers running the model, and a "farm" of JSP servers accessing this model. I am amazed that no one has stumbled onto this problem. If you have two Orion servers running, put the following code on one of the servers: Properties p = new Properties(); p.setProperty(Context.PROVIDER_URL, "ormi://target-host/application-name"); p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory"); p.setProperty(Context.SECURITY_PRINCIPAL, "user"); p.setProperty(Context.SECURITY_CREDENTIALS, "password"); InitialContext ctx = new InitialContext(p); You will need to replace target-host, application-name, user and password with values for your system. You will need to put the application-client.xml in to the proper directory. For a web application, this file should go into WEB-INF/classes/META-INF/application-client.xml. -AP_ -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ray Harrison Sent: Monday, April 02, 2001 8:16 PM To: Orion-Interest Subject: Re: Help me please "domain was nul" message is killing me here...

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.

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

Orion(web) - Orion(ejb) communication rough mini-how to
OK, I decided I would try to figure out how to get this working yesterday and here is what I came up with. We have two machines each running Orion: Machine A - contains the EJBs Machine B - contains the web stuff 1) Create an application on Machine A that contains the EJBs you want to be able to access from Machine B. 2) Create an application on Machine B that contains web elements that will access the EJBs on Machine A (This application must be named the same as the application on Machine A! Also See Warning below!) 3) Edit the rmi.xml file of Machine B to include a "server" element tag that points to Machine A. 4) The orion-application.xml for the application on Machine B must include a tag like: ejb-module remote="true" path="doesn't_seem_to_matter" / 5) I had to put the home remote interfaces of the ejb in the orion/lib directory on Machine B. It didn't seem to be able to find the class definitions otherwise, and I would eventually get this error: javax.naming.NamingException: Lookup error: java.io.IOException: Class Not Found : jason.HelloWorldHome; nested exception is: java.io.IOException: Class Not Found: jason.HelloWorldHome at com.evermind.server.rmi.RMIContext.lookup(JAX) at com.evermind.server.hm.f4(JAX) at com.evermind.server.hm.lookup(JAX) at javax.naming.InitialContext.lookup(Unknown Source) at __jspPage3_jtest_jsp._jspService(__jspPage3_jtest_jsp.java:39) at com.orionserver.http.OrionHttpJspPage.service(JAX) at com.evermind.server.http.HttpApplication.xj(JAX) at com.evermind.server.http.JSPServlet.service(JAX) at com.evermind.server.http.d3.sw(JAX) at com.evermind.server.http.d3.su(JAX) at com.evermind.server.http.ef.s1(JAX) at com.evermind.server.http.ef.do(JAX) at com.evermind.util.f.run(JAX) (I am very interested in the solution to this problem, and if anyone knows please post it to the Orion-Interest list.) 6) I didn't have to add any ejb-ref tags to my web.xml, I was able to access the remote EJB by doing the usual context lookup, narrowing, etc., from within a jsp. 7) Watch your web talk to the EJBs --- ! Warning ! --- Machine A must have at least the same applications that Machine B defines! If you don't then you will get a NullPointerException on Machine A that looks like: java.lang.NullPointerException at com.evermind.server.rmi.a7.gr(JAX) at com.evermind.server.rmi.a7.resolveClass(JAX) at java.io.ObjectInputStream.inputClassDescriptor(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at java.io.ObjectInputStream.inputObject(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at com.evermind.server.rmi.ba.hg(JAX) at com.evermind.server.rmi.ba.run(JAX) at com.evermind.util.f.run(JAX) I am speculating that this is because of the "shared" application namespace stuff that seems to be going on, but I could be way off base here. Note that you are allowed to have applications on Machine A that are not defined on Machine B. My biggest (or more frustrating) gotcha was making sure I could start both servers after I had placed the server tag in the rmi config for the web machine. The warning should explain what you need to do to avoid that. After that was the afore mentioned class location problem. Regardless, I hope this helps. -jason

Returning Collections from ejbFindXXX()
Hi,
Has anyone tried to return Collections from a BMP ejbFindAll() type of
operation?
I return an ArrayList of String objects, the client receives this list ok
but gets a cast exception on trying to extract the String from the list. eg.
public Collection ejbFindAll() throws java.rmi.RemoteException,
javax.ejb.FinderException
{
ArrayList v = new ArrayList();
v.add("First");
v.add("Second");
return v;
}
and the client code:
Collection coll = home.findAll();
System.out.println(coll.size() + coll.toString()); // this shows
correct count and contents: "2[First, Second]"
Iterator iterator = coll.iterator();
while(iterator.hasNext())
{
String s = (String)iterator.next();// class cast exception
System.out.println("Desc=" + s);
}
On closer inspection with a debugger it turns out the objects in the list
are of class __Proxy5, some sort of orion proxy object.
This appears to be a bug but I'd like to be sure in case its me. Has anyone
done this successfully?
I'm using orion 1.4.5, I cannot seem to upgrade with autoupdate due to
(probably) firewall restrictions.
TIA

RE: Help me please domain was nul message is killing me here...
I have had the same problem Alexto further muddy the matter I still haven't figured it out. I have opted to sipmply circumvent this option and do my own method of remote invocation (EJB in one server invoking an EJB in a another server). What I do remember reading , is that you need to set the "parent attribute" in the application definition in server .xml. If you look at the docs it specifies that this kind of scenario can be accomplished by doing just this.. i.e. the invoker is a child of the invoked. The problem I had, with this , is that I could never get it to work; I could never figure out the syntax.- parent ="ParentApp". - This only works if the other application is on the same physical server. The moment you try to append a server name to this application name i.e. parent = "remote-host/ParentApp" or even parent = "ormi://remote-host/ParentApp" this goes to hell !!! If this is supposed to work, that implies that the syntax tried out was wrong Anyway this might not be of any help, but you may want to try investigating the parent deal further (in server.xml when you define the application). It might lead to some undiscovered truth If you do find out, could you please let me know as well !! I developed a kludge to bypass this scenariowhich I would like to rep-lace with a functional soloution Good Luck !

Ray, the problem is quite simple. I have two Orion servers. One server is running an EJB application model, the other server is running JSP client application. From the JSP server, I try to access the EJB server, by creating an InitialContext with the same parameters that I would if I was trying to connect to the EJB application using a standalone client (appplication-client.xml and ApplicationClientInitialContextFactory). At this point, I get a NullPointerException on the Client (JSP Server) side telling me that the "domain was null". The exact same code, works correctly when running as a standalone application, however, when put into the JSP Server, produces this exception. Some people suggested using ApplictionInitialContextFactory, however, since ApplicationInitialContextFactory reads application.xml, I have no place to put my ejb-ref tags to reference the objects in the EJB application. Other people suggested playing around with rmi.xml. This, however, hardly seems standard. I am trying to write code that is J2EE compliant without having to use any of the Orion specific features. So I am at a standstill. It's hard to believe that no one ran into this problem. In many cases it does not make sense to deploy the client and server on the same physical machine. Our JSP clients are running on the public internet while our EJB models are running on the private internet not accessible from the outside. Also, since we have many clients, we anticipate having a "farm" of EJB servers running the model, and a "farm" of JSP servers accessing this model. I am amazed that no one has stumbled onto this problem. If you have two Orion servers running, put the following code on one of the servers: Properties p = new Properties(); p.setProperty(Context.PROVIDER_URL, "ormi://target-host/application-name"); p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory"); p.setProperty(Context.SECURITY_PRINCIPAL, "user"); p.setProperty(Context.SECURITY_CREDENTIALS, "password"); InitialContext ctx = new InitialContext(p); You will need to replace target-host, application-name, user and password with values for your system. You will need to put the application-client.xml in to the proper directory.

RE: Does any one has a solution for the domain was null message???
If you use the ApplicationClientContextFactory it will read META-INF/application-client.xml which is where you can specify the ejb-ref and env-ref elements... There still must be some other aspect of your situation that I don't understand. In answer to my own question, I finally discovered how the rmi authentication works in conjunction with an EJBUserManager. It was not clear from the error messages. After reading the article at orionsupport on the DataSourceUserManager, studying the orion examples and docs and an intuitive guess, I added the permissions to a group in the application's principals.xml, e.g.: group name=RMIUsers descriptionrmi users/description permission name=rmi:login / permission name=com.evermind.server.rmi.RMIPermission / /group (Can someone explain the permissions in relation to the groups or point me to a reference? I'm still not sure which of the two or whether both are required and why. It works for now...) This group name is added in the orion-application.xml which also directs the application to use the custom EJB user manager: user-manager class=com.evermind.ejb.EJBUserManager property name=defaultGroups value=ValidatedUsers / property name=home value=ejb/CustomEJBUserBean / /user-manager ... namespace-access read-access namespace-resource root= security-role-mapping group name=RMIUsers / /security-role-mapping /namespace-resource /read-access ... /namespace-access Now my application client is successful in connecting to the rmi server, authenticating a user account via the EJBUserManager and accessing my application.

EntityBean Events inside tx.
We would like our entity beans to propagate events in the same fashion than regular java beans. Therefore we must, for example, send events notifying of property changes inside the bean. The problem with this is that we don't know if this method was called inside a transaction that might be rolled back later on, and hence the property change event should not have been sent at all. Clearly, we want to propagate the events only when the transactions are commited. Is there a standard "pattern" to manage this sort of thing ? TIA Ramiro Diaz Trepat Opetra

web application classloading
short: Orion's classloading seems to be broken. It handles classes differently depending on whether they're loaded from WEB-INF/lib or WEB-INF/classes. I see related bugs in the Orion bugzilla database (http://bugzilla.orionserver.com/bugzilla/show_bug.cgi?id=340) with no comments or solutions metioned.. long: I'm having some troubles with the Orion web application classloader. I'm currently using Orion 1.4.5 (I tried "java -jar autoupdate.jar" but it only asks me "Overwrite /config/database-schemas/sapdb.xml" and doesn't seem to do anything else). I'm running Linux, Sun JDK1.3_02. I'm trying to get the IdooXoap 1.1.1 toolkit running (http://www.idoox.com). It is delivered in an unpacked WAR directory. Classes seem to load from the WEB-INF/lib directory, but the application fails when those classes from WEB-INF/lib try to use Class.forName() to load classes that are in WEB-INF/classes. (Confused yet?) Here's what the default setup is, and what works on most other application servers: IdooXoap/WEB-INF/etc/config.xml IdooXoap/WEB-INF/lib/IdooXoap.jar IdooXoap/WEB-INF/lib/log4j.jar IdooXoap/WEB-INF/lib/xerces.jar IdooXoap/WEB-INF/classes/demos/.. The servlet that is being called is inside of IdooXoap.jar, and it tries to load the demos from the "classes" subdirectory. This fails - ClassNotFoundException. Here's how I've tried to fix it: 1) Create "IdooXoap/WEB-INF/lib/demos.jar" with the contents of "classes/demos". This fails again with ClassNotFound. 2) Unpack all of the libraries from "lib" into "classes" (and then remove everything from the "lib" directory). This works!! 3) Create a giant JAR of all classes in the "lib" directory (and then remove the "classes" directory). This works too!! court

RE: findByXXX() with an ORDER BY parameter for Container-managed bean ?
From: Markus Holmberg [mailto:[EMAIL PROTECTED]] You are relying on an implementation detail of your container. The reason it has worked for you so far is because your container has used an instance of java.util.ArrayList/LinkedList, which indeed does guarantee order. But CMP Entity EJB's finder methods do not return java.util.List's! They return java.util.Collection. Your functionality will break when the container changes it's implementation. I'll bet a case of beer that you can't find a J2EE server that uses an unordered implementation for the Collection :-) I would guess that Orion actually walks the RowSet from the Iterator rather than trying to shove everything into core first. Otherwise finders are going to choke on big queries. I think assuming this behavior is reasonably portable. My only worry is whether or not other app servers let you customize the finder sql so easily. Jeff

RE: Servlet blues
By default, a single instance of your servlet will be created by the container to service all requests. The doGet() is not synchronized so it must be written thread-safe. Alternatively, you can have your servlet implement the SingleThreadModel interface. This instructs the container to create a pool of servlets and synchronize access to them. I do a lot of image generation from servlets, but since I have a reasonably finite quantity of images I don't bother with SingleThreadModel and just cache them in a synchronized HashMap. The overhead of creating the ImageBuffer, etc for the first instances is small. BTW, you might want to use the free Acme GIFEncoder (http://www.acme.com) instead of Sun's jpeg encoder. I believe the jpeg encoder is only available in the Sun JVM and jpeg encoding is pretty lousy for flat expanses of color anyways.

RE: Implementation inheritance with ejb...
I don't think you can have an inheritance structure like this. When you
define the parent relationship, the EJB container wants a method
'abstract Category getParent()' which does not exist.
I have a similar tree structure without the inheritance (also called
'Category'), and it works with some caveats. Watch out for the lack of
support for bidirectional relationships; I only store the parent
relationship and implement the getCategoryChildren() business method
with a call to ((CategoryHome)getEJBHome()).findByParent(). There are
other ways but I found this to be the most pleasant.
Inheritance wasn't really designed into the EJB specification. You can
use interface inheritance, but otherwise you're asking for pain.

I have a general concept of a TreeNode which could contain a

have defined a
basic TreeNode such as:
public class TreeNode ... {
public void setParent(TreeNode parent) throws RemoteException;
public TreeNode getParent() throws RemoteException;
public void setChildren(Collection children) throws RemoteException;
public Collection getChildren() throws RemoteException;
}
My TreeNodeBean, has the appropriate abstract functions.
Now, I have something called Category, which has a parent/children
relationship with other categories. So, when creating a
Category, I defined
it like this:
public interface Category extends TreeNode {
public String getName() throws RemoteException;
public void setName(String string) throws RemoteException
}
similary, I defined a CategoryBean as an abstract class which
is based on
TreeNodeBean, with the additional abstract functions to
get/set name. I
have created a one-to-many relationship between Categories,
using parent to
specify the parent for particular category, and children to
indicate the
children Collection.

Once that was over with, I copied the generated finder code

generated code:
THE ORION-GENERATED CODE REVERSES THE ORDER OF THE STATEMENT

Notice the criteria in the where clause: first is
CatalogEntryEJB.catalogIdentity, second is
CatalogEntryEJB.catalogLocale.
These are the two fields of the composite primary key of CatalogEJB, a
String and a Locale respectively.
Now look at the code that inserts the values for these parameters:
First is: statement.setString(1,
com.evermind.util.ObjectUtils.toString(primaryKey398.locale));
And second is: statement.setString(2, primaryKey398.identity);
The locale is being inserted where the identity should be, and
vice-versa.

I followed the instructions and noticed that the directions to install the sample application on Orion (as written) would not work. First it only mentions copying one xml file not action.xml (it mentions struts_config.xsl). Then it asks you to point the config setting to action.xml without copying it to the web application root. The directions seem to be missing some steps. I tried to improvise and tried to copy all xml (and tag definition files) files from WEB-INF to the web app root of the sample, but I am running out of ideas.

RE: Does any one has a solution for the domain was null message???
Well, I agree that it would be nice if you could get access to servers outside of Orion using the "client" approach, I don't think it necessarily defined in the J2EE platform specs. I took a look around the J2EE 1.3 specification, and the section J2EE.2.8 "Flexibility of Product Requirements" states: "This specification doesn't require that J2EE product be implemented by a single program, a single server, or even a single machine. In general, this specification doesn't describe the partionining of services or functions between machines, servers, or processes. As long as the requirements in this specification are met, J2EE Product Providers can partition the functionality however they see fit. A J2EE product must be able to deploy application components that execute with the semantics described by this specification." In section J2EE.2.11.3 "Network Protocols" it says that "This specification defines the mapping of application components to industry-standard network protocols. The mapping allows client access to the application components that have not installed J2EE product technology". Finally, in J2EE.8.2.1 "Application Assembly" subpart 3ii says "Dependencies that are not linked to internal components must be handled by the Deployer as external dependencies that must be met by resources previously installed on the platform. External resources must be linked to the resources on the platform during deployment." From everything I have read, it seems that Orion isn't violating any specification rules, since they are allowed to partition functionality as they see fit. Orion does allows multiple servers to intercommunicate, but it is the responsibility of the application deployer to specify those links (and it is specific to Orion). Since the web container is bundled as part of the J2EE Server, I don't think the specification requires that it has access to anything outside that specific server environment. I would like to hear the thoughts of others about this, and any experiences they might have had with access with remote containers/servers. -jason

MessageDriven Beans !
Hi all, This is a freaky thing that I have been experiencing. Here's the scenario: I have two sets of topics: a server topic and a client topic. The server topic is hooked to a Message Driven Bean. There is some logic involved that places a message on the "server" topic.In turn the Message Driven Bean is awaken and it odes some procesisng in its turn. Subsequently, when the processing is done, I publish a message onto a separate topic for a client. Everything works fine up to the point where the Message Driven Bean publishes on to the "Client " topic. Everything looks peechy, however, the client subscriber to the client topic never gets the message. If I try an external client that publishes a message onto the client topic, the subscriber gets it. SO my dillemma, and what's been driving me nuts for the last few days, is that, the bloody Message Driven Bean does something to the topic, and freezes it up. I can't think of any reason why it should , but it does. Has anyone out there experienced such problems with the message driven beans ??? If so could you please lend a helping hand to someone who is slowly going looney Any input is much apreciated ! Thanks !!! Bruno

Re: Returning Collections from ejbFindXXX()
The reason you're getting an exception is because the collection of Strings
you return from your EJB method is not the same collection that the client
receives. The client receives a collection of your EJB's remote interface
class, and that is the class to which you should cast the results.
Remember that it is the EJB container (Orion) which calls your EJB methods,
not the client. Orion receives your String collection and uses it to create
a collection of EJBs which are returned to the client code.

Subject: Returning Collections from ejbFindXXX()
Hi,
Has anyone tried to return Collections from a BMP ejbFindAll() type of
operation?
I return an ArrayList of String objects, the client receives this list ok
but gets a cast exception on trying to extract the String from the list.
eg.
public Collection ejbFindAll() throws java.rmi.RemoteException,
javax.ejb.FinderException
{
ArrayList v = new ArrayList();
v.add("First");
v.add("Second");
return v;
}
and the client code:
Collection coll = home.findAll();
System.out.println(coll.size() + coll.toString()); // this shows
correct count and contents: "2[First, Second]"
Iterator iterator = coll.iterator();
while(iterator.hasNext())
{
String s = (String)iterator.next();// class cast exception
System.out.println("Desc=" + s);
}
On closer inspection with a debugger it turns out the objects in the list
are of class __Proxy5, some sort of orion proxy object.
This appears to be a bug but I'd like to be sure in case its me. Has
anyone
done this successfully?
I'm using orion 1.4.5, I cannot seem to upgrade with autoupdate due to
(probably) firewall restrictions.
TIA
