Re: Orion price
Hello Rob, The price is definately not per year. The license agreement says as it does because you only get free upgrades for on year. However you may continue using what you have bought forver and ever. I'll check out the agreement to see if the text is implying something else, and if it does, we'll change it, we never meant it to be per year.

PROBLEM: Primary-child CMP object
Here is a simplified version of my problem:
I have a Person entity object that contains a list of phone numbers as string, which
encapsulates Person and Phone database tables joined by foreign key person_id.
When I create a person instance first and then fill in phone numbers information,
everything is fine and all the data is stored into their underlying tables properly.
However if I need to fill in all phone numbers during the creation of person instance
(i.e. in ejbCreate()), I will get a foreign key constraint error.
public Integer ejbCreate(...)
{
phones = new ArrayList();
phones.add("123-3456");
phones.add("888-");
phones.add("911");
}
I look like to me that Orion tries to create all the dependent objects first before
the primary objects and hence violates the underlying database constraint.
Could someone explain to me is there a reason Orion creates object in this order since
it doesn't quite make sense to me.
P.S. Here is my orion-ejb-jar.xml snap-shot

Quick Tips on SSL
This is quick tip list for getting SSL working on Orion: 1) Fairly good instructions at http://www.orionsupport.com/?key=ssl-howto 2) Install JDK1.3 for the purpose of generating you keystone and other associated files. It has the RSA algorithm in it. You don't have to run the server with it. 3) Build the associated SSL files on NT. 4) Be sure to check "Test SSL Chained CA Cert" at the Thwart step. 5) On the first step, when the keystone tool asks for you First and Last name DON'T DO THIS!!! Instead give the URL of the site you are attempting to secure! DAAA! 6) DON'T supply a second password. There is an option to do so called something like . Just hit return here. Now, can anyone post a summary of the steps to get a REAL certificate? Hmm. This is starting to feel like open-source software! :-() STeve Puntee-Business Software ArchitectTechnologent Inc[EMAIL PROTECTED]

Re: confusion about the use of context-root in orion
Hi, context-root is a "hint" to deployment tools and as such will be used by
the Orion deployment tools when suggesting a mapping at deployment time. The
actul root specified is a deployment setting though and as such doesnt
belong in the assembly descriptor. For instance a web-app can on the same
server be mapped to different roots on different sites etc. I agreee that
the spec is a little (very) uncler on this point.
Hope it helps!

I must correct myself. this is what the docs say: exclusive-write-access - Whether or not the EJB-server has exclusive write (update) access to the database backend. If it does it will speed up common bean operations and enable better caching. The default is true. So orion's default behaviour is not to be spec compliant in a scenario where other clients write to the database, which probably was a marketing decision ;-). so if you don't turn it off explicitely, it's not deterministic what happens in your scenarion. it depends on how the cache works and it's current state. btw. have a look at this validity-timeout - The maximum amount of time (in millis) that an entity is valid in the cache (before being reloaded). Useful for loosely coupled environments where rare updates from legacy systems occur. This attribute is only valid when exclusive-write-access="true" (the default). fiddling around with those two attributes might give you acceptable performance and still "some" deterministic behaviour depending on how strict you requirements are. haven't tried it but it seems to make sense. regards, robert (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de

confusion about the use of context-root in orion
hi,
I must say that I'm a little confused about the way context-root is used in
orion, which may be due to lack of understanding of the spec on my part.
say, I want to use a web application under a certain context-root
("/myroot") in a website. what I do is put an entry in the relevant
web-site.xml file like so:
works like a charm with everything (redirects etc.) being interpreted
relative to the contextPath "/myroot". now, what is the use of the J2EE
"context-root" element in application.xml? I get the impression it is not
being used at all. the spec doesn't say too much about the element ("sets
the context root"). does orion's root attribute in web-site.xml replace the
context-root element in J2EE? if I specify it nothing changes, even if I
put nonsense in there. I like the orion mechanism as it works and is very
flexible (I can use the same web-application under many context roots in
different websites) but it would be good to know what that does to spec
conformance.
some clarification on this matter would help.
thanks,
robert

Importing a cert from Thawte
I have now got a valid certificate from Thawte, (i.e a real one, not a test
cert). I am now trying to import it into my keystore without success.
I genereated my certificate request like this:
keytool -genkey -keyalg "RSA" -alias myalias -keystore keystore -dname
"cn=www.[mydomain].com, ou=[MyCompany], o=[My Company], c=SE, S=[Mystate],
l=[mycity]" -validity 360
keytool -certreq -keyalg "RSA" -alias myalias -file
www.[mycompany].com.csr -keystore keystore
The only thing that differs from the Orion docs is that I use an alias
'myalias' instead of the default 'mykey'.
When getting my certificate from Thawte I could choose from a number of
formats. The two that seems to fit is
'Standard Certificate Format' (BASE64 encoded, DER encoded X.509v3 cert.)
'PKCS #7 Certificate Chain' ("Newer servers and development toolkits support
"certificate chains". This format allows Thawte to deliver a full
certificate chain to you, which in turn makes for superior key management
and flexibility.")
When trying to import either one of the above I get:
keytool -import -keystore keystore -file mythawtecert.cer -keyalg
"RSA" -alias myalias -trustcacerts
Enter keystore password: mypassword
keytool error: java.lang.Exception: Input not an X.509 certificate
After reading the docs on keytool, I am still not completely sure if to use
"-alias myalias" so I tried that too:
keytool -import -keystore keystore -file mythawtecert.cer -keyalg
"RSA" -trustcacerts
Enter keystore password: mypassword
keytool error: java.security.cert.CertificateException: Unsupported encoding
Does anybody have any idea what is going wrong here?
Thanks,

Re: Integration with existent www-servers
Hello Stanislav, The answer depends on what you want. If you want to have apache act as web server and Orion only as EJB server, you can remove the default web site server from Orion or move it to another port than 80 and have the EJB accessed from application-clients. If you want Orion to serve part of your site's context and let Apache serve the other part (like Orion serving JSP and Apache serving html, gif, php, cgi:s or something else) there is a TunnelServlet provided, which is still in beta and not documented, but you can test it to see how it works for you. You set the TunnelServlet up like this (you can set it up in global-web-application (this is assuming that Orion is running on port 80 and Apache on 8080): tunnel com.evermind.server.http.TunnelServlet targetRoot http://localhost:8080/ And you add the mappings for the content you want Apache to handle: tunnel /*.html tunnel /*.gif These two mappings make Apache handle any *.html and *.gif requests. The tunnel servlet will get more sophisticated later on to be able to do things more conveniently, but it should work already.

Your options are to run orion's webserver alongside your existing web-server (on another port/ip), or to create some kind of wrapper extention for your existing server to forward certain type of requests to orion. The latter option is fairly trivial under apache with something like mod_perl, and is how a lot of other servlet engines work (jserv, tomcat, jrun, etc) but your performance will be impacted badly as each web-request requires an additional tcp connection to be made. > And I'd like to know how to start only > application server, not whole orionserver. whole orionserver == application server. If you mean you want to start the server without the web-service, you can remove all tags from server.xml -Joe Walnes
to list admins: please set reply-to header
hi, could the list admins set the reply-to header in the emails the listserver sends? it would make things easier and is standard behaviour of other listservers. thanks, robert (-) Robert Krüger (-) SIGNAL 7 Gesellschaft für Informationstechnologie mbH (-) Brüder-Knauß-Str. 79 - 64285 Darmstadt, (-) Tel: 06151 665401, Fax: 06151 665373 (-) [EMAIL PROTECTED], www.signal7.de
Re: Entity beans and database
this is incorrect. the container has to ensure that when a transaction is started the entity beans involced in that transaction have to be in sync with the underlying datastore. depending on your transaction isolation level this locks the record associated with your entity in the db during the transaction. if you modify the record with another client, the next transaction that is started and involves that entity should reload the current state, otherwise the container doesn't conform to the spec. so if you deleted records, the load operation should throw an exception. however, most containers (including orion) allow you to specify a flag that indicates that your server is the only thing writing to the database to avoid the expensive load operations at the beginning of each transaction. if you specify that and still modify the database from outside, you're on your own and can no longer rely on the spec. the effect that you cannot recreate an entity that you deleted manually looks like it's a caching problem (somewhere there's a hashtable of primary keys kept in memory that's not updated when the database record is deleted manually). so if you use the exclusive-write-access option then you're to blame. if you don't, I guess orion shouldn't behave that way and you should probably consider it a bug and post it to [EMAIL PROTECTED] but I might be wrong. regards, robert At 14:48 20.07.00 , Nick Newman wrote: >Hi Rick, > >The EJB spec says that once the entity bean is loaded from the database, >the container (Orion) doesn't have any responsibility to keep track of any >possible changes to the database.

Re: Entity beans and database
Uhh boys , I think I can help a bit I agree that the problem is that you're working behind the server but ... the solution is to do something in order to it understantd what are you doing. I suggest you make a "commit" commnad in SQL every time you modify something in the database through SQL sure it will work and the server will understand the changes PLease I would be very grateful if you mail back to tell us wheter I'm correct or not. - David Sierra Fern ndez Ingeniero Tecnico de Telecomunicaci¢n AULA RETECAL (CEDETEL) Universidad de Valladolid Campus Miguel Delibes E-Mail: [EMAIL PROTECTED] 47011 Valladolid (SPAIN) -- -- Sierr@ -- On Thu, 20 Jul 2000, Nick Newman wrote: > Hi Rick, > > The EJB spec says that once the entity bean is loaded from the database, > the container (Orion) doesn't have any responsibility to keep track of any > possible changes to the database.

Integration with existent www-servers
Please, explain me how to integrate orionserver with other web servers like Apache. And I'd like to know how to start only application server, not whole orionserver. Any help appreciated, Stanislav Bernatsky
