Com.sap.sql.log.OpenSQLException during EntityManager Call

Question

Hi!
I deployed an EJB3 session bean on the NW 7.1.
The aim is to use JPA with this bean.
I configured the "persistence.XML" for the bean project and packed it into the jar File and a "data-source-aliases.xml" which is included in the ear file. The packaging of the ear-file is done with the developerStudio and deployed on the NW 7.1
Then I created a dataSource project which contains the "data-sources.xml" and deployed this too.
Here is my data-sources.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE data-sources SYSTEM 'data-sources.dtd'>
<data-sources>
    <data-source>
        <data-source-name>JPA_SDN_EXAMPLE_DS_555</data-source-name>
        <driver-name>ora10</driver-name>
        <sql-engine>native_sql</sql-engine>
        <jdbc-1.x>
            <driver-class-name>oracle.jdbc.driver.OracleDriver</driver-class-name>
<!-- *** Edit the following entries appropriately *** -->
            <url>jdbc:oracle:thin:@10.XXX.7.27:1521:orcl</url>
            <user-name>bdeadm</user-name>
            <password>dmin</password>
<!-- *** End editing ***  -->
        </jdbc-1.x>
    </data-source>
</data-sources>
My deployed session bean looks like this:
@Stateless(name="WorkerBean")
public class WorkerBean implements WorkerRemote {
     @PersistenceContext(unitName="JPAModel")
    private EntityManager em;
     public String sayHello() {
The last step was the deploment of the oracle driver on the NW7.1 under the "Application Resources Overview". The driver I named "ora10".
Now if I call my Bean shown above with its Entity Manager Call for the injection I got the following exception:
Caused by: com.sap.sql.log.OpenSQLException: Error while accessing porting layer for ORACLE database via getSessionId().
     at com.sap.sql.log.Syslog.createAndLogOpenSQLException(Syslog.java:148)
     at com.sap.sql.jdbc.direct.DirectConnectionFactory.createPooledConnection(DirectConnectionFactory.java:532)
     at com.sap.sql.jdbc.direct.DirectConnectionFactory.createDirectPooledConnection(DirectConnectionFactory.java:157)
     at com.sap.sql.jdbc.direct.DirectConnectionFactory.createDirectPooledConnection(DirectConnectionFactory.java:117)
     at com.sap.sql.connect.factory.PooledConnectionFactory.createPooledConnection(PooledConnectionFactory.java:119)
     at com.sap.sql.connect.factory.DriverPooledConnectionFactory.getPooledConnection(DriverPooledConnectionFactory.java:38)
I have no idea, whats wrong. Perhaps my driver is wrong or not set properly ?
Can anybody help me please ?
Thanks in advance,
Hendrik

Answer 1

I have tried that.
[EXCEPTION]
*com.sap.sql.log.OpenSQLException: The SQL statement "SELECT * FROM EPD.SAPEPDDB.UME_EP_SLD" contains the syntax error[s]: - Open SQL syntax error: table names must not specify a catalog name (delete "EPD". before "SAPEPDDB"."UME_EP_SLD")*
Database name must be Ok, because i can access to other tables which are in the same DB...
Thanks for your help
