Hi,
I am trying to get my DataSource
(with Connection Pooling) to run.
In the examples one always gets the
DataSource from JNDI and I have the
impression that everytime I want
to get my connection from DataSource
via a Context lookup.
Wouldn't it be better to read the
data source once in a singleton class
and then just get it back, i.e.
private DataSource ds;
...
public static void getDataSource() {
// if data source unknown read it from context
if (ds == null) {
try {
Context ctx = new InitialContext();
ds = (DataSource) ctx.lookup("java:comp/env/jdbc/myDataSource");
}
catch (..) {..}
}
return ds;
}
This should be faster than accessing the context
every time you need a datasource or a connection.
Could this lead into problems?
Any suggestions?
Cheers,
Holger
