How can I use the Connection Pool with DB2

Question

Hi All,
I am facing the problem with the usage for the Connection Pool.
I want to use DB2 via JNDI lookup.
But when starting the Weblogic server, Error occured with the following message.
<Error> <JDBC> <Cannot startup connection pool "MyJDBCPool" Cannot load driver class : com.ibm.db2.jdbc.app.DB2Driver>
DB2 and Weblogic are on the same machine.
In case of the use of remote DB2 database, I also encountered the same error.
Configurations are as follows.
<JDBCConnectionPool DriverName="com.ibm.db2.jdbc.app.DB2Driver"
MaxCapacity="10" Name="MyJDBCPool"
Password="{3DES}gCGsOfD9M6iwOtgL2v/NpA==" Targets="myserver"
TestConnectionsOnReserve="false" TestTableName="test" URL="jdbc:db2://localhost:6789/yongjoo"/>
<SNMPAgent Name="mydomain"/>
<JDBCDataSource JNDIName="acsdb" Name="acsdb" PoolName="MyJDBCPool" Targets="myserver"/>
Could you please give some information about this problem? I will appreciate your kindness.

Hi Joe,
Thanks your help.
Perhaps It's my fault for Weblogic console's setting.
After I reset the target server in console, Error message disappeared.
But, when I call the TestCode, I encountered another error message. The error
is NameNotFoundException.
When lookingup the JNDI name, NameNotFoundException errer occured. I tried to
change my setting and JNDI name, but the results are the same.
Would you please give me some information about this one more time? I will be
appreciated for your help.
Follows are Config.xml
<JDBCConnectionPool DriverName="com.ibm.db2.jdbc.app.DB2Driver" MaxCapacity="10"
Name="MyJDBCPool" Password="{3DES}gCGsOfD9M6iwOtgL2v/NpA==" Targets="myserver"
TestConnectionsOnReserve="false" TestTableName="test"
URL="jdbc:db2://localhost:6789/yongjoo"/> <SNMPAgent Name="mydomain"/>
<JDBCDataSource JNDIName="acsdb" Name="acsdb" PoolName="MyJDBCPool"
Targets="myserver"/>
and follows are TestCode,
url = "t3://localhost:7001"; //default URL
datasource = "jdbc/acsdb";
Context ctx = null;
Hashtable p = new Hashtable();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, url);
try{
ctx = new InitialContext(p);
System.err.println("initialContext(p)"+ctx); <-- success
ds = (DataSource)ctx.lookup("java:comp/env/jdbc/acsdb");
}catch(NameNotFoundException ne){
throw new ConnectionException(); .
}catch(NamingException ne){
throw new ConnectionException();
