Unfortunately, I don't believe this is an appropriate forum to address this question to. The ODBC protocol has nothing to do with Java or EJB.

Entity EJB deployment on Oracle through JDeveloper 3.2
I have a project which is using Oracle 9iAS as the for the web server. There were intial plans to use the 8i database within the 9iAS machine as the place where the EJBs would be stored. There was a comment from the Oracle support people that the EJBs would be better off stored on the backend. We are trying to do the same.
We have experienced mainly two problems
1) While trying to deploy the container managed beans through JDeveloper, just after creating the deployment profile, an error ORA - 00904 comes up. (no columns). Then there is a prompt to install BC4J. On doing that the error comes up again and while it goes further, it says 'Exhausted ResultSet'. But the BMP entity beans are working OK.
2) We had a bug report from the Oracle people on entity bean support through JDeveloper on non-NT machines. But we have been trying to deploy beans on the Solaris DB using JDeveloper and we keep getting 'peer socket disconnected errors'. I'll try the workaround which was suggestesd by the Oracle people to solve the problem and get back on this.
I don't know how Oracle will measure up to the performance when EJBs are running. But the problems mentioned above would have to be solved first.
Can anyone help out?
Thanks in advance.
Aby PhilipI can't resist a comment here. Oracle folks seem to always recommend putting the EJBs in back-end database. How many real-world enterprise-scale applications (i.e., one's that would need EJBs at all) have a non-shared back-end database? And in those cases, who in their right mind would accept running application code in the back-end database? I guess Oracle just hasn't really bought in to the concept of multi-tiered applications. The whole reason for separating the business logic tier from the EIS tier is to insulate the EIS services from the demands of the business logic code.
So from that perspective, I would highly recommend running an 8.1.7 instance in your middle tier to house your EJBs. Then you can hook up to your EIS tier either with database links, or (for better performance) by caching data in the EJB database from the EIS tier.
As for your specific issues, I can't help with the first. On issue 2, I am installing the 8.1.7.1 patch set today and I'll let you know if it fixes the JDeveloper --> Solaris deployment problem.

Jdk 1.2 clients running ejb deployed on oracle 8.1.5
Oracle claims that it is possible to run jdk 1.2 clients with ejb on oracle 8.1.5 in the faq : http://technet.oracle.com/products/oracle8i/htdocs/jserver_faq/815faq0012.html
If you have JDK1.2 on the client side and:
8.1.5 clients connecting to an 8.1.5 server: This does not work, because of conflicts with the ORB supplied in JDK1.2.
8.1.5 clients connecting to an 8.1.6 server: This does not work, because of conflicts with the ORB supplied in JDK1.2.
8.1.6 clients connecting to an 8.1.5 server: This works provided the "server" portion of the application is developed/loaded using the client side tools and jars that are supplied with 8.1.5.
What do they meen with 8.1.6 clients? and how to make 8.1.6 clients?Oracle 8.1.6's JVM uses JDK 1.2. Oracle's 8.1.6 JDBC drivers support JDBC2 and JDK2. The 8.1.6 drivers are available for download from OTN under the Technologies section.
If you develop a client (application, applet, servlet, JSP, etc.) using the Oracle 8.1.6 JDBC drivers, then this is considered an Oracle 8.1.6 client.

nullWhat I did to solve this problem was to
create a simple RMI remote object that
resides outside the database JVM and that
serves as a proxy EJB client for your java
stored procedure. The stored procedure can
invoke a method on the remote RMI object
which then looks up the EJBean's home
interface and invokes the relevant method on
the bean's remote interface, and relays any
return values back to the java stored
procedure.
Hope this helps,
Avi.

Problems deploying EJB on a oracle 8i server
We are trying to deploy a EJB on a oracle 8i server. We crossposted this question in BI Beans forum also.
For doing so we are using the following command:
"deployejb -republish -temp temp -u sys -p sys -s sess_iiop://NLWS122:2481:
LOKAAL -descriptor AQServerReceive.ejb AQServerReceive.jar"
It seems that everything goes allright (we can trace the classes in the database) but we get this message:

Thx for helping.Hi Ralph,
I don't know if you are aware of this, but Oracle has replaced
the database embedded EJB container (a.k.a. "aurora") with an
external EJB container named OC4J (Oracle Containers for J2EE).
OC4J is available in both stand-alone version and as part of Oracle's
application server product: 9iAS. Although the database embedded
EJB container still exists in the latest database versions (as
far as I know), Oracle has -- for a long time, now -- been discouraging
its use in favour of OC4J.
More information on OC4J is available from:
http://technet.oracle.com/tech/java/oc4j/content.html
Good Luck,
Avi. -

I had tried using -Xms / -Xmx options (upto 1 GB).
The trace of exception gets delayed (from being displayed on the console) as the memory size is increased; but after sometime it starts getting displayed on the console.
Even though this exception is displayed on the console, the Timer Bean continues to execute upto sometime before it finally crashes!
If anyone has encountered such problem; would appreciate if you could share the solution.
Regards, VidyadharHi guys, I have the same problem. I have an application EAR file with two modules (EJB and WAR starting in this order). The application can schedule a process via EJB timer. In this case restarting the server I receive the error above. If I change the modules start order --> WAR - EJB the server start correctly, but the application scheduler fails (the persistency is not working) with this error:

Can't access EJB deployed on remote OC4J - what am I doing wrong?
I'm unable to access an EJB deployed on a remote OC4J instance (ie, part of a 9iAS installation on another machine vs local in JDeveloper).
I've reverted to a stupid-simple EJB in hopes of getting it going prior to trying my actual code. The EJB works fine in JDev (9.0.3) - I 'run' the EJB to start the local OC4J instance, run my client code (generated via the "New Sample Java Client..." option in the Navigator context popup) and all is well.
I then create an EAR file via the the "Create EJB Jar Deployment Profile..." context popup of the ejb-jar.xml node, followed by "Deploy to EAR file" from the context popup of the resulting ejb1.deploy node. I next "Deploy EAR File" via the "Oracle Enterprise Manager" that comes with 9iAS (the :1810 port). After successfully deploying, I modify my client code in JDeveloper, specifying the new connection information for the remote machine via the Hashtable constructor of InitialContext and attempt to run it. I've tried a number of Context.PROVIDER_URL forms, including: ormi://registered_pingable_host_name:23791/deployed_application_name
ormi://registered_pingable_host_name:23791/session_deployment_name (from the <enterprise-beans><session-deployment name="xxx"/></enterprise-beans> section of my orion-ejb-jar.xml file, as per a tip in this forum)
I've tried prefixing ormi:// with http:, but get no response whatesoever in this case.
I've also tried it without the port number (this port number matches that in my remote OC4J's <oc4j_instance_home>/config/rmi.xml file).
On the Context.SECURITY_PRINCIPAL and Context.SECURITY_CREDENTIALS settings, I've tried various values, generally using the 'admin' user, with passwords taken from:
<oc4j_instance_home>/principals.xml
<oc4j_instance_home>/application-deployments/application_name/principals.xml
I've also tried matching the password in the jazn-data.xml, to no avail - this password appears encrypted anyway, but thought I'd give it a try on the off-chance that it was just a randomly-generated password - no go.
I've also tried SCOTT/TIGER, anonymous, etc. Incidentally, the 'deactivated' attribute of the <user> tag is set to "false" in my principals.xml files.
No matter what I do, I always get back "javax.naming.NamingException: Lookup error: java.net.ConnectException: Connection refused: connect"
Additionally, I get this same message when I try to establish an Application Server Connection via JDev.
Clearly, I'm missing something critical (and probably simple), but I can't for the life of me figure it out.
Any help would be much appreciated!
Thanks,
Jim StollOk, well this is a bit strange...
3103 - 3103 also fails, and some experimentation has led me to find that any time that I specify a range smaller than 6 (3101 - 3106 works, 3101 - 3105, 3101-3101, 3103-3103, etc does not), the OC4J instance will not restart. I get "An error occurred while starting. The opmn request has failed. From opmn: HTTP/1.1 204 No Content Content-Length: 0 Content-Type: text/html Response: 0 of 1 processes started. Check opmn log files such as ipm.log and ons.log for detailed." in the OEM window (I specify the RMI port range, hit Apply, go to the OC4J instance home page, see that the Status is 'Down', hit Start, and get that message.) <ORACLE_HOME>/product/iasinfra/opmn/logs/ipm.log tells me:
02/12/03 09:41:12 There is no rmi port left for starting an OC4J process. Please check oc4j's port property in OPMN's configuration file.

02/12/03 09:41:12 start_proc_req: failed to start a process in GID OC4JJim2, type: 2
If I bump it up to 3101 - 3106 or higher, it starts right up. Running opmnadmin debug, as suggested by Venky (thanks Venky!), yields:

3456376 14964 00000000 OC4J Alive 1 0 3004 3104 3204
Which is what I would expect, given the specified range of 3101-3106. Trying each of these ports in turn, I've found that I can hit the EJB successfully on 3106, but 3101 - 3105 all fail with:
javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: No such domain/application: Project7_2; nested exception is:

InitialContext.java:350
void Samplemypackage9.MySessionEJBClient1.main(java.lang.String[])
MySessionEJBClient1.java:15
I'm a little concerned about assuming the high-end of the range to be the active port on a regular basis (though thus far, among about 20 - 30 tries spaced over 20 - 30 minutes, it has been...) - I guess I can have my code loop through the range until it finds a good port or exhausts the list, but that seems a bit excessive.
Can you think of a reason that my OC4J instance won't start with a range size of less than 6? I'm on 9iAS 9.0.2, if that makes any difference.
Thanks,

nullHi Mak_GK,
Sorry for the late answer.
Make sure that your client project has the following libraries:
JDeveloper runtime
Oracle 8.1.5 JDBC
Connection Manager
<your generated jar file from the EJB>
JBO Runtime
OAS Runtime
JBO OAS Runtime
Also, sometimes it helps to stop and re-start OAS after deploying your EJB.

Access Denied with EJB Deployment to 8i with JDeveloper

Perhaps you should be checking if the user you wish to deploy
EJBs to has at least JAVAUSERPRIV.
As SYSTEM
grant JAVAUSERPRIV to <user>;
Good luck

Create an EAR in JDeveloper to deploy on Oracle AS 10g
I have a J2EE project with EJBs and JSPs. I am using JDEVELOPER as my IDE. I need to deploy my application on ORACLE 10G APP SERVER.
I need to create an EAR file consisting of my EJBs and JSPs to deploy the appln.
When i go into Deployment Profiles in JDeveloper and try to create an EAR file, it does create the EAR file but the contents of the file are only 2-3 xml files, there is nothing else in it.
I am wondering how on earth do i need to create my EAR package so that i can deploy on Oracle APP Server.
This is actually very urgent... so i would really really appreciate and thank you if someone could help me out....
Thank you very much in advanceSee thread Re: Create EAR in JDeveloper to deploy on Oracle AS 10g

URGENT : ejb client in Oracle 8
We developed a EJB client. This client should be called from an Oracle Database 8.1 (ejb compliant). But, each time we tried to load weblogic.jar, we have several errors into Oracle (ie : ORA-29534 NamingContext could not be resolved)
Do you have an idea why ? Someone already developed an ejb client into Oracle 8.1 ?They are reccomended because the next step going from your simple single EJB
to anything interesting, like adding more EJB's adding web-apps, adding
web-services etc etc involves ears. If the setup and overhead for an EAR is
easy, then just start there.
But no if you just doing helloworld you of course dont have to ears.

My understanding is ejbc has been deprecated and replaced with appc.Moreover,
BEA is encourgaging developers to deploy ear files. All I want todo is
to use
ant to deploy a jar file with a single EJB in it. I'm not findingthe WL
documentation
very helpful. Hopefully, you'll have better luck than I.

nullAre you using JDeveloper? If yes then go to File|New->Snippets
and select 'Example JServer EJB Client' to create an EJB client.

It's sess_iiop not iopp ;-)

Is it possible to monitor all calls into all EJBs deployed on a server?
Is there any way of monitoring all calls into the EJBs deployed in a server?
I'd like to be able to externally log the calls, and perhaps do some monitoring at the call level, without modifying the EJBs themselves. Something along the lines of servlet filters for servlets, but for EJBs instead..
JBoss has a nice plugin interface, and one could either extend the Logging plugin, or write another one, that can do this.
But is there an analog in other J2EE servers (e.g. weblogic and websphere)? Or is that a standard or clever way of intercepting all calls? (I suppose one could use Ethereal, but I was hoping for a higher-level solution).
Duke dollars available!Hi,
In JBoss they use Log4J to log and intercept the Bean calls and JDBC calls. You can use Log4J to do the same with other servers also, cause I configured OC4J(Oracle 9iAS) Server to use log4J and it worked for me. I think other servers can also be configured to use log4j. I've only tried this with JBoss and OC4J. I don't have much experience with other servers.
So, my advise is : try LOG4J and try to configure server to use LOG4J
Hope this works!

Hi,
I try to deploy my first ejb. I'm pretty sure I have done everything right, but I'm getting errors anyway. Does anyone recognize this error message?
