1. Re: Accessing a DataSource
davidjencks May 15, 2003 8:49 AM (in response to gseel)Are you accessing from within the jboss vm and are you sure the jndi is configured to not go through rmi? (normally this means you just say new InitialContext and dont put any jndi.properties anywhere in a deployable)

Thanks for response.
Yes running inside the JBoss vm. Actually running as a stateless session bean wanting to use DAOs for persistence.
Relevant code is:
context = new InitialContext();
dataSourceName = (String) context.lookup("java:/PointbaseDS");
dataSource = (DataSource) context.lookup(dataSourceName);
Have done a list on the context and it lists a number of names (e.g. XAConnectionFactory and queue) but nothing like java or PointbaseDS.

3. Re: Accessing a DataSource
gseel May 15, 2003 9:09 AM (in response to gseel)Looks like the classic copying code without understanding it error. Got rid of the two stage lookup and I think it's working. Now can't get a connection because of 'no principal' but that just sounds like a config problem in my stuff.
Thanks. -
4. Re: Accessing a DataSource
richardye May 16, 2003 8:15 AM (in response to gseel)I have the same problem while trying to access data source within jboss vm using JBoss_3.2.1. I have done the following:
1) change the oracle_ds.xml to include my data source info
<jndi-name>DevDs</jndi-name>
my oracle url</connection-url>
then put the oracle_ds.xml into deploy directory
2) I define System property in properties-service.xml
DataSourceJndi=java:/DevDs
3) In my stateless session bean I call one of my application class JndiDataSource(JndiDataSource is included in my application library jar, the jar is simply deployed into deploy directory) as
JndiDataSource.getConnection() {
String jndiName = System.getProperty("DataSourceJndi");
InitialContext initialContext = new InitialContext();
Object jndiDataSrc = initialContext.lookup(jndiName);
}
then I got DevDs not bound error even though I saw the log file says 'java:/DevDs' is bound to WrapperDataSource
and I don't believe I have any jndi.properties in deploy directory
****** client side error ********
