RE: Orion and IIS
Title: RE: Orion and IIS What you should really do is set-up an IIS virtual root (e.g. /protected). You then set this virtual root to forward to, for example, http://localhost:8088 SSL can be run on the virtual root, which will encrypt all incoming traffic as it has the following pattern: CLIENT - IIS - ORION However, the traffic back from Orion to the client will not be encrypted, as the outbound port from the (Orion) server won't be secured using SSL. If this a requirement you may have to think more carefully about the solution. One of the best ways I've seen of encrypting data between a browser and a server is to run the encryption software on a firewall (if this option is open). Most commercial, and even some freebie firewalls come with an encryption module that allows you to protect traffic up the point where it passes through the perimeter of your network, which is essentially all you're really interested in. There is no drastic need to encrypt point to point, and SSL performance through firewalls tends to be a lot better.

Orion 1.2 JSP Samples
I downloaded and installed Orion 1.2.0 on a Suse 6.4 Linux machine with JDK 1.2.2 and have the following problem: When I start the server, it tells me that it cannot find the WEB-INF/web.xml file for initializing the default web site. The directory structure on Linux is case sensitive, and there is a web-inf directory in the default-web-app tree. When I rename it to WEB-INF, the server initializes fine, but when I try to run the JSP samples, it cannot find its classes. Am I doing something wrong here? The installation of 1.3.XX on another machine worked fine.

Re: Restricting servlet access
When I brought up this issue with one of the authors of Orion I was recommended to set the servlet-webdir attribute of orion-web-app (in orion-web.xml or global-web-application.xml) to "[NONE]". Not sure if this actually disables the feature, or if its just meant to obfuscate the path to something unusable. It would be preferable if this feature would be disabled by default in Orion. (The servlet-webdir attribute in global-web-application.xml does not seem to be used as a default value when auto-deploying, which requires manual adjustment of this each time..

Transaction problems...
We have been using transactions successfully for a while nowor so we
thought.
Here is the scenario. We have a series of registration pages on our site.
We gather all the information we need, and at the end
we create a stateless session bean passing it all the information we need.
In this session bean, we have seven tables that get
modified by calling the create method of seven different entity beans. We
wrap the whole series of method calls in a usertransaction
similar to the following:
code
InitialContext context = null;
TransactionManager manager = null;
context = new InitialContext();
manager = (TransactionManager)context.lookup
("java:comp/UserTransaction");
manager.begin();
try {
org = createOrganization();
orgLoc = createOrganizationLocation();
orgUsers = createOrganizationUsers();
orgLocUsers = createOrgLocationUsers();
createEquipmentTypeOrganization();
regStatHist = createRegistrationStatusHist();
notifyUser();
}
catch(RegistrationException re) {
manager.rollback();
throw re;
}
manager.commit();
/code
From the surface, this looks to work normally. If an excpetion is thrown
in any method, the entire transaction gets rolled back.
however, our problem lies within the order that Orion calls the methods on
the EJB. When the above code is *NOT* wrapped within
a transaction, only the ejbCreate of each entity bean gets called. Nothing
else. However, wrapped in a transaction like the
above, immediately after the ejbCreate method is called, the ejbStore
method is called. Now here is the big reason this is a bad thing.
All of our tables have triggers on them that set two of the columns. These
triggers are set in the database on the insertion of a row. But when
the ejbStore method is called, it does not sync itself back up with the
database to get the newly created values in these columns, and does an
update
with the locally held values, which happen o be null. It seems that
ejbLoad should be called *before* ejbStore gets called.
Can someone tell me what I am missing here? In order to get around this
problem, we have resorted to hardcoding the proper trigger generated
values into the EJB, but that is a very unflexible solution. Any help
would be greatly appreciated.

An example to connect to a remote client (based on Orion-Primer)
Hi, A little, perhaps useful, contribution to the documentation. I have been experimenting with Orion. In the end I want to connect to the Orion server from a browser. As a first step I have added a remote client to the Orion-Primer from Ernst de Haan. Maybe it is usefull from some other people new to Orion. Frank Hi, I've got a simple remote client running. As it took me quite some time, maybe other people might find this example useful to get started. All this is based on the Orion-Primer of Ernst de Haan. Have a look on his site www.znerd.demon.nl for a more detailed explanation of the JSP example before running the remote client. In the attached archive files you find: - the unchanged sources from Ernst, - an addapted application.xml file (did I do that right?), - two extra files: HelloClient.Java and application-client.xml and - an addapted build file. If you have successfully compiled the example as described by Ernst using my sources, you will find the necessary 'orion-primer-client.jar' in the rel/ directory. B.T.W. It is fun to see the autodeploy working. Check the log of the server while running 'ant clean' and 'ant'. You'll see the autodeploy picking the file up. You run the remote client as follows: 1. Make sure you have a proper java setup on your remote machine. 2. Copy a jndi.properties file from a orion demo (e.g. the cart demo) to directory X. You'll find it in the directory orion/demo/ejb/cart. Make sure it refers to the server and not localhost. 3. Copy the following jars from the orion installation dir to directory X: - orion.jar - ejb.jar - jndi.jar - jaxp.jar - parser.jar - jdbc.jar - mail.jar 4. Copy the orion-primer-client.jar to directory X on your remote machine. 5. Run the following command: "java -classpath .:orion.jar:ejb.jar:jndi.jar:orion-primer-client.jar hello.client.HelloClient" If all runs fine you will get some messages on your screen ending with: "Exit cleanly". == HelloClient.java == The code is straightforward, but as it is an example and things can go wrong. Amongst others: - First thing is to get a context. You'll run into trouble here if your jndi.properties are not right. - Next step is the get the Home Interface. If the application-client.xml is not right or server does not run (or you point to the wrong server) things will break here. I guess there are more ways of having fun ... == application-client.xml == The example file is pretty straightforward. It describes under which name you can find the Home Interface, in our case 'ejb/HelloHome'. You have to use that same name in your source file 'HelloClient.java'. The type of the Bean is of course the same as in the ejb-jar.xml: Session. The other entries in the application-client point to the right Home and Remote interfaces. == classpath / jndi.properties / jars == The '.' in the classpath is necessary to pick up your jndi.properties file. The first three jars mentioned (orion, ejb, and jndi) in the classpath are necessary for the execution environment. The Orion runtime environment will look for the other jars you have copied (mail, jdbc, parser and jaxp) in the directory where the orion.jar file resides (directory X in our example). The reason why you need mail.jar and jdbc.jar is unclear to me. You get error messages if don't include them. I understood from Karl Avedal that Orion is working on a smaller 'client.jar' that also contains a subset of orion.jar. That would be great for connecting to Orion from a browser. That would take less downloading. Next step for me is to get it running using an applet and a browser. All that work and who will notice the difference with the JSP example 8-).

CMR / CMP problem on the client side
Hello, i just started using the OrionServers CMR mapping for a simple CMP Bean. The bean has a "public Set getItems()" and returns a CMR Set of other CMP Beans. Creation of Beans using the create() using the homes create methods works flawless. All entries and dependencies get generated in the DB. The getter also works great on the server side since i put in a System.out.println in the EJB's getter implementation and it shows the set of read Objects. Alas the Client invoking the getItems() just sits there and waits for the result. At least i assume it does. Nothing happens any more after the call. My setup is Win98, JDK1.3, mySQL shareware and OrionServer 1.0.3 or 1.2.0. That problem occurs with both versions of Orion. Is there anything i can do ? I tried to get some info from the mail-archive but couldn't find anything relating to that problem. THX in advance, Udo

Would you please to tell the deployed file structure or tell me how to make file structure? Could I find gui tool to deploy ejbs in orion server? Could I use the deploytool provided by Sun for orion server? Jinpeng
Re: Transaction problems...
I'm just guessing, but have you tried setting exclusive-write-access="false"
in your orion-ejb-jar.xml file? It sounds like Orion is doing some
optimisation to speed things up because it thinks it has exclusive write
access to the database - but your triggers are going behind Orion's back
without it realising. Turning this off might force Orion to call the
ejbLoad.

EJB stub classes and stand-alone remote java client
I've been trying to get my standalone java client to access EJBs on a remote machine, but with no luck.I've deployed a J2EE application with my EJBs in it. But I can't figure out how to generate the stub classes. I can't find the Orion tool to generate the stub classes that the client would normally reference from the CLASSPATH(as described in "Java 2 Enterprise Edition Developer's Guide" page 95). How do you generate the stub classes that enable the client to communicate with the enterprise bean? This is a simple thing to do with the deploytool that comes with Sun's J2EE Reference Implementation.During deployment you simply select a checkbox labelled "Return client Jar" when you deploy the application. I don't understand how the client can resolve the EJB classes if you don't have the client stubs to include in your CLASSPATH. I keep getting a java.lang.ClassNotFoundExceptionexception. Also, what else do I need to deploy to my client machine, just orion.jar? Thanks, Paul Knepper [EMAIL PROTECTED]

classpath for third party tools
Hi We are integrating a third party java application with orion but both of them will be running on the same VM. As per the docs we dropped all the third party jar files into the orion/lib directory and the server was able to load their classes. These third party classes are looking for config files of their own, the directory path for which needs to be specified in the classpath. Problem: When running on the same VM started by orion server they cannot find the path to these config files through classpath. java - cp %classpath%;..\..\some path -jar orion.jar does not work. so I put the path in application.xml file as a tag library path="..\..\some path" / that doesnt work either I also put these tags in server.xml ..no luck.

Orion is doing it's own manual loading of those JARs from the lib directory. Any suggestions would be highly appreciated.

As indicated by an e-mail from Karl Alvdal of the Orion team earlier today they are working on a lightwight library which will remedy this. As for makeing jars with home and remote interfaces, it's easy to automate this task with a shell-script, bat-file or using ant. The later is what we found preferbal.

I've deployed a J2EE application with my EJBs in it. But I can't figure out how to generate the stub classes. I can't find the Orion tool to generate the stub classes that the client would normally reference from the CLASSPATH (as described in "Java 2 Enterprise Edition Developer's Guide" page 95). How do you generate the stub classes that enable the client to communicate with the enterprise bean? This is a simple thing to do with the deploytool that comes with Sun's J2EE Reference Implementation. During deployment you simply select a checkbox labelled "Return client Jar" when you deploy the application. I don't understand how the client can resolve the EJB classes if you don't have the client stubs to include in your CLASSPATH. I keep getting a java.lang.ClassNotFoundException exception. Also, what else do I need to deploy to my client machine, just orion.jar? Thanks, Paul Knepper mailto:[EMAIL PROTECTED] [EMAIL PROTECTED] File: ATT1.html
RE: EJB stub classes and stand-alone remote java client
The "home" class wasn't found. I followed the directions from the reply from Torgier Lerker (Thanks Torgier) and things work fine now. I jar'ed up the home and remote interfaces and deploy them with my client everything works fine. Are you saying that I don't even need to do that?

For some reason Orion does not need you to generate stubs. I do not fully understand how they get away with that. Wrt. your ClassNotFoundException, which class can't be found? It could be a bogus setting in the jndi properties or a bogus application-client.xml?

request dispatcher problems under load !?!
hi all, we were stress testing our app today with real users and found that at high loads some users were winding up with others' session info. as we autopopulated text controls with previously entered information, some users found that info entered by others on other client machines was popping into their screens. has anyone else seen anything like this before? the stress on the server was particularly heavy as we were running a trace logger at the time, which of course involved serious i/o pressure, so this wasn't in response to particular user load (about 10 people executing fairly involved searches). as soon as we shut down the trace function, the problem disappeared, but we're worried that once we get 100-200 people at once onto this app that we'll have problems again. we thought that perhaps request dispatcher might be the root of the problem. does anyone know if it is supposed to be thread safe? any other ideas? we're running orion 1.1.37 on redhat linux, using the blackdown 1.2.2-RC4 jdk/jre. thanks, bradley mclain usmoving.com __ Do You Yahoo!?

Re: Linux and IBM JDK v1.3?
It turns out that I was running a development version of IBM's JDK. A very subtle "dev" in the middle of the version string tipped me off. Upon download of the production version everything appears to work. Certainly a dubious first post to the mailing list. Thanks for your offer of help.

Re: request dispatcher problems under load !?!
Hello Bradley, Can you reproduce this and set us up with an .ear that shows the same behaviour? If it is an Orion bug it's very serious and we want to be able to fix it right away, that's not something that should be able to happen :) Also, in the future, if you send suspected bugs to bugs@ that helps us to solve the problem quicker, since this list is a rather high-traffic one and some of us don't read every mail on the list (it's meant for the community...).
