OAS - EJB connectivity
Hi,
I've been trying to connect my EJBs with OAS(4.0.8 and 4.0.8.1) on NT. I could not get it connected. Before we continue to spend more time to explore, can somebody tell me if he/she ever made it work successful?
Raghu, I notice that you've been giving out great advice to others. I tried your methods and I still could not get it connected.
EJBs on OAS 4.0.8 (I also tried 4.0.8.1 ), today), does anybody make it work at all? Or, we just made some silly mistakes in our configuration.
We really need to get it work.
Thanks.
Raghu,
In general, I do have the following unknowns:
1. when I start up OAS (4.0.8 or 4.0.8.1), I get an error on "ORAPERF8.DLL" not found in my path. I could not find this file from my entire PC nor all my Oracle CDs. This has not caused me much problem. I don't know if it causes my problems with EJB connectivity.
I reinstall OAS many times and this problem does not go away.
2. I had my Oracle 8i and OAS on the same NT. According to the release notes, we have to do some workarounds and I did. It still did not solve my EJB problems. I installed Oracle 8.0.5. No help.
3. I have had many different problems during EJB deployments and I had then overcome. Right now, the program hangs when connecting (narrow) to the home interface.
Tommorrow, I will reinstall my NT, Oracle DB and OAS. I hope I have better luck this way.
By the way, I've tried the ways you suggested including http://www.domain.com:80/ows-bin/rmproxy.ior
. I had no problem with it.

[Jeveloper + EJB client - EJB on OAS] Problem connecting
I having problems getting a simple client from within JDeveloper 3.0(Code snippet - OAS/EJB Client) talking to a simple EJB on OAS 4.0.8.

Is there a way to do that? To use dynamic EJB connections?
Hello Developers,
I have developed a security web application using EJB,
Jaas with customer provider
I used DBSystemLogin module
I want to fined a way that the EJB connection change each time when the user login.
I used the HR as the main schema.
I created three schemas that I want to use them as users:
-Lina
-Salem
-Ahmad
I granted Roles to users on hr tables.
additional, created my own roles in data base and granted to my users:
ADMINISTRATOR Lina - can see all records
EMPLOYEE Ahmad -can see the records added by this employee
CUSTOMER Salem - can see the records belongs to this customer
In developer 10.1.3.3
I created Order Entity been using HR database connection, created session been,
Modified web.xml:
-security roles["ADMINISTRATOR","EMPLOYEE","CUSTOMER"])
-Loginconfig (Form-based authentication: login page, error page)
-Security constraints: ord on /faces/Orders.jsp to ADMINISTRATOR,EMPLOYEE,CUSTOMER.
I created Orders.jsp page contains order table.
Now, I want that when the user login as Lina to switch the EJB database connection to Lina, so the displayed order table achieves ADMINISTRATOR roles that created in database,means opening database session for user Lina and use it.
and so on for user salem and ahmad.
Is there a way to do that? To use dynamic EJB connections? To achieve authentication based connection? to implement the user database roles on the client side? To specify the database connection at run time?
That is possible using forms but I don’t want to use forms.
I want to reed the roles from database according to the user.
I hope to get answers soon,
thanks.Does JNDI do this job?

URGENT:Testing deployed OAS EJB Aplication (JNDI Problem)
Please I need urgently help on this subject matter:
Environment:
OAS 4.0.8.2a on NT 4.5 SP5
Jdeveloper 3.1
Oracle 8R2
After succesfull deployment of BC4J aplication on OAS I want simply test it. When I click to test on the appModule on the tree, the dialog asking the connection information appears..I choose OAS option from the drop down box.
The error message I get is:
"apps/ejb/ClientesProjectOAS/pkgClientes/PkgClientesModule is not the name of a registered component"
I have tried with other variants too taking into account what OAS Administration shows..but no luck!
Now, WHAT SHOULD BE PUT TO THE "JNDI PATH" and "CLIENT JAR PATH" options. This is the most confusing point to me and there are practically no valid/good information on online help.
Thanx.
Best regards,
Ari Supperi
[email protected]I have (almost) the same problem. Any idea? My weak english must be the reason, but I cannot find out what to enter into the JNDI and the Client jar path during testing my OAS deployed AppModule.
Thx,

Oracle9i DB?Hi,
on small thing to check (or perhaps do):
Make sure that you are using the JDBC drivers from the Oracle9i
DB client e.g. copy the classes12.jar from the ORACLE_HOME of
the database client into OC4J_HOME lib.
Also, one thing that might help is to define an explict Oracle
datasource e.g.
- Set class to value of Oracle DataSource class
- Use only the location logical name
- Returns Oracle implementation of java.sql.Connection
<data-source
class="oracle.jdbc.pool.OracleDataSource"
name="jdbc/oracle/PooledDS"
location="jdbc/oracle/PooledDS"
username="scott"
password="tiger"
url="jdbc:oracle:thin:@<host>:<port>:<SID>"

Ejb connect to remote jndi resource
Hi,
I want my ejb to connect to a jndi reource (in this case a jms topic) on another server (also AS7). I'm trying to use somthing like this:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://remoteserver:3700");
ctx = new InitialContext(env);
tconFactory = (TopicConnectionFactory) PortableRemoteObject.narrow(ctx.lookup(JMS_FACTORY),TopicConnectionFactory.class);
tcon = tconFactory.createTopicConnection();
tsession = tcon.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
topic = (Topic) PortableRemoteObject.narrow(ctx.lookup("jms/MyTopic"), Topic.class);
tpublisher = tsession.createPublisher(topic);
I get the following exception:
WARNING ( 2944): CORE3283: stderr: javax.naming.NameNotFoundException. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0
Anyway, it throws the exception on the
ctx = new InitialContext(env);
So, if this is not the way to connect to a resource on another server, what's the correct way?

this makes testing of your client programs easier, you can find the error trace on which line and saves lot of time.
