ResourceException: Access not allowed (when trying to grab a connection from weblogic pool)

Question

I am using WLS7 with SP1.
I just recently migrated from WLS6.0. When my code tries to grab a
connection from the pool, it throws an exception
java.sql.SQLException: Pool connect failed:
weblogic.common.ResourceException: Access not allowed
at weblogic.jdbc.pool.Driver.connect(Driver.java:202)
Does anyone know if anything changed from 6.0 to 7?
Here is a piece of the code that throws exception.
Driver driver =
(Driver)Class.forName("weblogic.jdbc.pool.Driver")
.newInstance();
conn = driver.connect("jdbc:weblogic:pool:" +
dbName, null);
Thanks in advance.

Do you know how to change security setting on the connection pool?
Thanks.WebConsole:
1.Compatibility Security => ACLs
Create a new ACL,
name : weblogic.jdbc.connectionPool.yourPoolname
permission : reserve, reset
group : everynone
2.Services => JDBC => Connection Pool
Create a new Connection Pool
ACL Name : weblogic.jdbc.connectionPool.yourPoolname
In 'Target' tab, choose server and click the Apply button

Hi Jung,
Could you try providing weblogic user name and password
in the properties?
Could you also check security setting of the connection pool?

Well that is exactly what I am doing. The variable dbName is database
connection pool name that I created in weblogic console. Again, it
worked
in WLS6 but after migration, it stopped working.
Thanks.

In my code I am supplying name of the connection pool already
created
in
weblogic server. I am asking you to get connection from the pool
using
pool
driver.
In your case you are trying to create connection straight to
database
using pool
driver.
What I am asking is pass name of the connection pool instead of
database
name.
Thanks,
Mitesh

What would be the difference between your code and mine? Mine
simple
appends dbName string value for connection pool name at the end of
"jdbc:weblogic:pool:"? And why same exact code would work in WLS6and
not
work in WLS7?
Thanks.

conn = driver.connect("jdbc:weblogic:pool:" +
dbName, null);Instead of doing this what if you use
Connection conn =
myDriver.connect("jdbc:weblogic:pool:myConnectionPool", null);
Will you please try this and see if that helps?

Try As described below:
The following example demonstrates how to use a database
connection
pool
from a servlet.
Load the pool driver and cast it to java.sql.Driver. The
full
pathname
of
the driver is weblogic.jdbc.pool.Driver. For example:
Driver myDriver = (Driver)
Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Create a connection using the URL for the driver, plus
(optionally)
the
name of the registered connection pool. The URL of the pool
driver
is
jdbc:weblogic:pool.
You can identify the pool in either of two ways:
Specify the name of the connection pool in a
java.util.Properties
object
using the key connectionPoolID. For example:
Properties props = new
Properties();props.put("connectionPoolID",
"myConnectionPool");Connection conn =
myDriver.connect("jdbc:weblogic:pool", props);
Add the name of the pool to the end of the URL. In this case
you
do
not
need a Properties object unless you are setting a username
and
password
for using a connection from the pool. For example:
Connection conn =
myDriver.connect("jdbc:weblogic:pool:myConnectionPool",
null);
Note that the Driver.connect() method is used in theseexamples
instead of
the DriverManger.getConnection() method. Although you may
use
DriverManger.getConnection() to obtain a databaseconnection,
we
recommend
that you use Driver.connect() because this method is not
synchronized
and
provides better performance.
Note that the Connection returned by connect() is an
instance
of
weblogic.jdbc.pool.Connection.
Call the close() method on the Connection object when youfinish
with
your
JDBC calls, so that the connection is properly returned to
the
pool. A
good coding practice is to create the connection in a try
block
and
then
close the connection in a finally block, to make sure the
connection
is
closed in all cases.
conn.close();
