iBATIS Error in configuration xml

Question

i'm using iBATIS in my project. and my SqlMapConfig.xml is

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
    <transactionManger type="JDBC">
        <dataSource type="SIMPLE">
            <property name="JDBC.Driver" value="oracle.jdbc.driver.OracleDriver" />
            <property name="JDBC.ConnectionURL"
                value="jdbc:oracle:thin:@apludc01dat01-oravip.com:61961:irawbp" />
            <property name="JDBC.Username" value="xxxxxx" />
            <property name="JDBC.Password" value="xxxxxx" />
        </dataSource>
    </transactionManger>
</sqlMapConfig>

and i'm getting following error
