Re: What documentation?
Thanks Gary! It does help. Danut At 06:41 PM 2/26/2001 -0700, Gary Shea wrote: The same thing was bothering me, because having to modify orion's deployment descriptors was getting old. It turns out that you can make the orion web, ejb, and application deployment documents be part of your distribution. I create simplified versions that have just the stuff I care about in them, for instance: orion-application autocreate-tables="false" treat-zero-as-null="false" /orion-application By putting these into the appropriate places in your .ear or directory heirarchy, orion will find them and incorporate the information you specify in them into the final deployment descriptor that lives in the application-deployment directory. It's pretty slick. Hope that's useful. Gary _ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
RE: jsp form-based authentication
Go inside "orion.jar" and extract "EJBUser*.class" files then use reverse engeneering to get the java code and you will see exactly what you need to implement. Then go into "orion-application.xml" file and add user-manager class="com.acme.security.CustomUserManager" property name="blah" value="blah" / /user-manager You also have to pack into a jar all the files (the equivalent of EJBUser* files) needed to the security and copy it into the lib folder. Then go into web.xml and set the proper role names, login-config, the constrains, etc. I hope it helps.

Weblogic (and the high priced products like Websphere) are great, if you want to pay the price. They come with nice tools like front end gui's, good documentation, paid support, etc. But if you look for the opinions of developers who have used these products, and compared them to Orion, jboss, etc., they would say the EJB capacies are no better then the other high priced products. In order of ranking, here's how I look at the other products. 1 Orion -- This product is ready now, but I haven't seen anyone from this list run a Sears store on it. 2. Jboss (www.jboss.org) -- The founders are very bright, have five hundred developers on the projects, have EJB heavies contributing to the list, and it's a very easy to use product. Personally, even though it is ready for production now, I would wait for it to mature a bit more. It's like a fine wine -- drink it now, and it is OK, or allow it to age a bit then drink it (like jboss 3.0 final). 3. Openejb (www.openejb.org) - this project has a very bright and well known person heading it, and it is slated to be intergrated with Tomcat and Apache. It has yet to prove itself, as it is not yet ready for production release. But it has good future promise. 4. Jonas (www.evidian.com/jonas) - This is a good product, but it is not as advanced as the other two open source products and I don't think they have as many people behind them. 5. Enhydra enterprise (www.enhydra.org). If you like the enhydra application server, this product has potential. But it is not production ready yet and it intergrates with the jonas server. In summary, Orion is here now but can it run Sears? Jboss is ready but I would let it mature a bit more for production environments. Openejb and Enhydra have great potential, but they are not ready yet and have to prove themselves. Jonas is OK but I prefer the other open source alternatives. -Original Message- From: Anthony W.

Oracle database and connection pooling
Hi,
I am new to EJBs so I apologize if my question sounds silly. I am trying to
configure Orion to use Oracle 8 and pooled connections.
This is how my data-source looks like:
data-source
class="com.evermind.sql.ConnectionDataSource"
ejb-location="jdbc/MyApollo"
location="jdbc/OracleCoreDS"
pooled-location="jdbc/OraclePooledDS"
name="Oracle"
schema="database-schemas/oracle.xml"
xa-location="jdbc/xa/OracleXADS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="system"
password="manager"
url="jdbc:oracle:oci8:@APOLLO"
inactivity-timeout="30"
/
I am trying to implement a BMP and here is the code I am using to get the
connection:
public void setEntityContext(EntityContext ec)
{
...
Context initialContext = new InitialContext();
ConnectionPoolDataSource dataSource = (ConnectionPoolDataSource)
initialContext.lookup( "jdbc/OraclePooledDS" );
}
and later on
public Connection getConnection() throws SQLException
{
...
return dataSource.getPooledConnection().getConnection();
}
I get the folowing exception in my client code when I create the bean
javax.ejb.EJBException: com.evermind.sql.OrionPooledDataSource
at com.evermind.server.rmi.ba.invokeMethod(JAX)
at com.evermind.server.rmi.a1.invoke(JAX)
at com.evermind.server.rmi.a2.invoke(JAX)
at __Proxy2.create(Unknown Source)
at SelectTestClient.main(SelectTestClient.java:117)
that seems to be thrown
when the execution reaches the following line of code:
ConnectionPoolDataSource dataSource = (ConnectionPoolDataSource)
initialContext.lookup( "jdbc/OraclePooledDS" );
Thanks!
Danut

I'm not sure if you can use the CLASSPATH to accomplish the same thing, but frankly I'm not clear on how orion decides where to find things! I agree. Why do I have to copy the file(s) there instead of using the CLASSPATH? Shouldn't I be able to point to where Oracle installed the driver files?
