DataSource-class pool-JNDI-bind-lookup

Question

Hi,
I am a beginner in this subject and it is confused. I read that
the best way to use the connections is from a DataSource. There
are 2 ways to configure it:
1- From the data-source.xml file
2- Or using InitialContext, Context and bind method from a java
program loaded in the startup.
If so, which one is better?
On the other hand, there are some classes I can use, for
instance:
1- OracleConnectionCacheImpl
2- OracleConnectionPoolDataSource
etc.
which one is better?
Thank you very much for any comment.
Andres.

Answer 1

Hi:
upon further research, i find that the data
that was used in State class at binding does not change on any update,
like via foll -
State s = (State)ic.lookup(JNDINAME);
s.addHashtableEntry (key, val); or
s.setDesc ("new desc");
next time i lookup State class the hashtable entry is missing and desc is
old and not "new desc".
any help appreciated.
thanks

Hi:
I am using jdk1.3, weblogic6.0
I am binding a state class like ->
public class State implements Serializable {
private String desc;
private Hashtable sessions;
onto the JNDI tree. Binding is done like initialCxt.bind (name,
_state);
and state's sessions has one entry in it and state's desc is set.
I then use another client to do _initialCxt.lookup (name) on same
weblogic JVM.
The _state object is returned with correct value of desc; but the
sessions
hashtable is empty and the single entry is gone. I do see also the the
State's finialize () method is called.
Can anyone explain why i am losing hashtable information ?
How do I make this work in weblogic jndi with hashtable info ?
thanks
