RE: INTERESTING FOR DEVELOPMENT TIME: Central location for classes and still able to use hot deployment
There is very simple solution to this problem - make ORION server embedded. I use it. That's it. -Original Message- From: Marcelo Schroeder [SMTP:[EMAIL PROTECTED]] Sent: ? 06 2001 7:57 To: Orion-Interest Subject:INTERESTING FOR DEVELOPMENT TIME: Central location for classes and still able to use hot deployment I think this is something that a lot of people in the list would like to have: A central location for java classes in production or live mode (located in a network drive for instance) and and classes in development mode, so when a class doesn't exist in the development location, Orion would pick them up from the production/live location, and that with Orion still being able to hot-deploy for EJBs, servlets and helper classes shared by both ejbs and servlets. OK, I almost got there... I will share my success and also ask for some help to complete the puzzle: Classpath/classloader issue: 1) My ejbs and helper classes go in the ejb section. Hot deployment is triggered by touching orion-application.xml. Since the ejb classloader takes precedence over the servlet classloader, classes loaded here can be accessed by the servlet classloader and the auto reload feature can still be used by touching orion-application.xml. 2) Servlets and servlet specific beans go in the web section. Central location for production/live classes 1) Servlets: by using the classpath element in the orion-web.xml file it is possible to make Orion search for classes first in your development directory and if it doesn't find them there, then it searches in the production/live directory. Example: classpath path= file:///C:/proj1/developmentclasses file:///C:/proj1/developmentclasses / classpath path= file:/fileserver/proj1/productionclasses file:/fileserver/proj1/productionclasses / Instead of directories (where you would the expanded classes) you could also point to jar files. This solution works fine and the hot deployment still works also fine. 2) EJBs: this is my problem, I was not able to find a way to have the same classpath set up I have for servlets and get the hot deployment to work. You can use the library tag in the same way as the solution for servlets above, but you lose the hot deployment feature. So, my question is: is there a way to set the classpath for EJBs (first local classes, then production/live classes) and still be able to use ejb hot-deployment? Any contribution will be highly appreciated. Thanks a lot.

Transaction rollback problems because of incomplete orion-ejb.jar
Hi, I'm using orion 1.5.2 and I have the following problem: I have a session-bean that is accessing a datasource in transaction context. I have added an orion-ejb.jar in deployment jar/WEB-INF, containing a resource-ref-mapping pointing to the EJBDS for I want transaction support for this datasource. session-deployment... resource-ref-mapping location="jdbc/myEJBDS" name="jdbc/myDS" / /session-deployment After I deploy the application I can see in the deployment-directory that Orion only succesfully copiesall setting form my orion-ejb.jar for the entity-beans but fails to copy the settings for my session beans. The resource-ref-mapping for the sessionbeans lacks the location. session-deployment... resource-ref-mapping name="jdbc/myDS" / /session-deployment As a consequencethe datasource doesn't point to the EJBDS and therefore will not participate in a transaction, that is, transaction rollbacks do not affect the changes made through this datasource. The datasources.xml file looks like this: data-sources data-source class="com.evermind.sql.DriverManagerDataSource" name="DS" location="jdbc/myDS" xa-location="jdbc/xa/myDS" ejb-location="jdbc/myEJBDS" connection-driver="com.sap.dbtech.jdbc.DriverSapDB" url="jdbc:sapdb:DS" username="DBA" password="DBA" inactivity-timeout="30" schema="../../config/database-schemas/sapdb.xml" / /data-sources So, help!

2 parameter finder finding wrong thing
I am using EJB 2.0 and have a finder method that takes 2 parameters (e.g. the WHERE clause looks something like WHERE columnOne = ?1 AND columnTwo = ?2). No matter what I do, it does not return the right entity. I have tried single-object return, Collection return, narrowing, not narrowing, checking parameters, etc. I am running Orion 1.4.7 on HypersonicSQL for my testbed. Any ideas?

RE: Transaction rollback problems because of incomplete orion-ejb.jar
Ron, Take a look at bug 512. Your orion-ejb-jar.xmlis being overwritten with a double deployment of the application. Same thing happened to me. AFAIK, the only work around is to use version 1.5.1 or earlier. I reproduced this bug with a modified atm application.

ejb-jar.xml -- orion-ejb-jar.xml bug? finder parameters
I have discovered that when creating a finder with 2 parameters, the resulting orion-ejb-jar.xml that gets generated by Orion outputs finder-method query= instead of finder-method query=$columnOne = $1 AND $columnTwo = $2 for the finder example below. Single-parameter finders seem to generate the correct query. Has anyone experienced this problem? Is there a work-around or should I report this as an enhancement request or bug? Please don't tell me I have to edit this file by hand or some sort of processing during a build! - Kit -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Kit Cragin Sent: Sunday, July 08, 2001 12:30 PM To: Orion-Interest Subject: 2 parameter finder finding wrong thing I am using EJB 2.0 and have a finder method that takes 2 parameters (e.g. the WHERE clause looks something like WHERE columnOne = ?1 AND columnTwo = ?2).

RE: Transaction rollback problems because of incomplete orion-ejb.jar
Just looked at bug 512. The behavior is very similar to what I'm experiencing.Oninitial deployment the orion-ejb.jar file is copied to the deployment directory. THis is also ok in my case. Problems start arising similarly after redeployment of the ejb module. After this the orion-ejb.jar is incomplete, that is, ONLY my sessionbeans lack the specified location in resource-ref-mapping. My entitybeans are ok however. Modifying the orion-ejb.jar by hand after initial deployment seems to work but that is not a acceptable procedure.

Re: ejb-jar.xml -- orion-ejb-jar.xml bug? finder parameters
Kit, Yes, you have to edit the file by hand. I know that isn't what you wanted to hear, but it's alot nicer than what JRun was asking us to do for CMP (writing the full query for everything, it wouldn't generate a single findBy or create). You can edit the orion-ejb-jar.xml, then include it in your ejb.jar. Just remember that the only time this file gets copied over is on initial deployment. Jeff.

RE: How can I get UserTransaction or TransactionManager
Hi HK, I am getting puzzled now on this. Maybe you could try UserTransaction ut = context.getUserTransaction(); where 'context' is the SessionContext or EntityContext variable which is declared at the top of the EJB as a variable. Kind Regards Aby
RE: Orion 1.5.2 and ORM Map bug (SHOW STOPPER)
I have checked this out and it does not seem to be the problem. The orion-ejb-jar.xml file remains intact. If I remove the deployment directory and do an initial deployment, all data created while the server is up is readable. Any data that already existed in the database is unreadable. This is now a very serious problem for us and may require re-writing a large portion of the application to work-around it! Regards, Simon.
RE: How can I get UserTransaction or TransactionManager
Hi HK, you can't get UserTransaction from an Application-Client-or RMI-Client-Context. This (optional) feature is not supported by Orion.
