Java EE (Java Enterprise Edition) General Discussion

Hi!
I am having this configuration..
Application Server:weblogic 5.1
RDBMS:oracle 8.1.5
DataBase Instance:REDS
Jdk: jdk1.3
platform: win2000

i have created a connection pool by adding this code in
my weblogic property file...


weblogic.jdbc.connectionPool.testPool=\
url=jdbc:oracle:thin:scott/tiger@localhost:1251:REDS,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=4,\
maxCapacity=10,\
capacityIncrement=2,\
allowShrinking=true,\
shrinkPeriodMins=15,\
refreshMinutes=10,\
testTable=dual,\
props=user=SCOTT;password=tiger,\
allow=everyone

weblogic.jdbc.DataSource.testDataSource=testPool


when i start my weblogic server it throws these errors....
