Caught "com.evermind.server.rmi.OrionRemoteException" while attempting to find all De

Question

I am getting the following error while running JSP. Can anyone guide me.
Caught "com.evermind.server.rmi.OrionRemoteException" while attempting to find all DepartmentBean entries.
com.evermind.server.rmi.OrionRemoteException: Database error: Io exception: The Network Adapter could not establish the connection; nested exception is: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
Add entry
I have doubt in
My rmi.xml file
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE rmi-server PUBLIC "Orion RMI-server" "http://xmlns.oracle.com/ias/dtds/rmi-server.dtd">
<rmi-server port="23791" >     
     <!-- A remote server connection example -->
     <!-- <server host="the.remote.server.com" username="adminUser" password="123abc" /> -->
<!--     <server host="169.254.162.207" username="admin" password="welcome" /> -->
<!--     <server host="prg-fg9s9g12dnz" username="admin" password="welcome" /> -->
     <!-- path to the log-file where RMI-events/errors are stored -->
     <log>
          <file path="../log/rmi.log" />
     </log>
</rmi-server>
If I give server host line My oc4j server is NOT initialized.
In My Data Sources file :
     <data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="jdbc/DBConnection"
          location="jdbc/OracleCoreDS"
          xa-location="jdbc/xa/OracleXADS"
          ejb-location="jdbc/DBConnection"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          username="RajiveShukla"
          password="pujavrms1"
          url="jdbc:oracle:thin:@localhost:1521:wbs"
          inactivity-timeout="30"
     />
And JSP which I run is :
<%
* list.jsp
* Lists all the entries stored through EmployeeBean. This JSP is the only JSP
* that will actually connect to the entity bean. On success, it will save a
* reference to the entity bean in the session. So there will be one reference
* to the bean per session.

Hi Avi,
Thanks,
I have already used earlier..
the data-sources file is as under.
     <data-source class="com.evermind.sql.DriverManagerDataSource" name="jdbc/DBConnection" location="jdbc/OracleCoreDS" xa-location="jdbc/xa/OracleXADS" ejb-location="com.webstore.Department" connection-driver="oracle.jdbc.driver.OracleDriver" username="RajiveShukla" password="pxujxa" url="jdbc:oracle:thin:@PRG-FG9S9G12DNZ:1521:wbs" inactivity-timeout="30"/>
</data-sources>
The username and password and sid, I can connect in the sqlPlus
Do we have to give remote server name in rmi.xml.. It is not initilizing the J2EE server if we give that.??
I am using thin driver , if any change or any settings please write me..
Thanks in advance..
Rajive
