Hi Armin
This is my ejbCreate()
public void ejbCreate() {
InitialContext context = null;
try {
context = new InitialContext();
OjbPbFactory ojbFactory=
(OjbPbFactory)context.lookup("PBFactory");
PersistenceBroker broker =
ojbFactory.getInstance().defaultPersistenceBroker();
}catch(NamingException e){
//throw new ServletException("Error looking Data Source", e);
}
}
Here everythink goes well, but I need this lines in the Dao and not here
The object returned by the lookup in an istance of OjbPBStartup.
Then I do ojbFactory.getInstance() and I get an instance of
PersistenceBrokerFactorySyncImpl in the dao too.
The problem is that in the Dao when I call
pbf.defaultPersistenceBroker(), where pbf is the istance of
PersistenceBrokerFactorySyncImpl, I got the error.
The mistery is why it work correctly in ejbCreate and not in the Dao.
I read yet the lines you told, and I thought that the problem coud be in
the datasource definition:
I send it to you if you can have a look ;-)
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="srvOracleDS"
location="jdbc/srvOracleCoreDS"
xa-location="jdbc/xa/srvOracleXADS"
ejb-location="jdbc/srvOracleDS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="srv_des"
password="srv_des"
url="jdbc:oracle:thin:@192.168.80.212:1521:ORA92"
inactivity-timeout="30"
/>
I'm not very esperienced with this and I copied it from an example.
I don't Know exactly what do location, xa-location, and ejb-location.
My repository-database.xml is
<jdbc-connection-descriptor jcd-alias="default"
default-connection="true"
platform="Oracle" jdbc-level="2.0"
jndi-datasource-name="jdbc/xa/srvOracleXADS"
protocol="jdbc"
username="srv_des"
password="srv_des" eager-release="false"
batch-mode="false" useAutoCommit="0"
ignoreAutoCommitExceptions="false">
Have I done all right (well, no, of course)
Thank for the help

Hi Alessandro,
the code causing the CCE is

org.apache.ojb.broker.accesslayer.ConnectionFactoryAbstractImpl.newConne
> ctionFromDataSource(C
> onnectionFactoryAbstractImpl.java:195)
in this method OJB does:
<snip>
InitialContext ic = new InitialContext();
ds = (DataSource) ic.lookup(jcd.getDatasourceName()); <===!!!
</snip>
So it seems that the object returned by the lookup is not instance of
DataSource or it's a side-effect of another problem.
Could you describe your test more detailed?
You lookup OjbPbFactory in ejbCreate method?
And the DAO use an session bean or does directly access OJB via JNDI
lookup?
regards,
Armin
