xml配置文件如下：
 <datasource name="localoracle"
            helper-class="org.ofbiz.entity.datasource.GenericHelperDAO"
            schema-name="hrplan_jiaxing_090109"
            field-type-name="oracle"
            check-on-start="false"
            add-missing-on-start="false"
            join-style="ansi">
        <read-data reader-name="main"/>
        <!-- <jndi-jdbc  jndi-server-name="localweblogic"  jndi-name="hbdsSource" oraxzgl/> -->
        <inline-jdbc
                jdbc-driver="oracle.jdbc.driver.OracleDriver"
                jdbc-uri="jdbc:oracle:thin:@192.192.192.182:1521:@testora"
                jdbc-username="hrplan_jiaxing_090109"
                jdbc-password="hrplan"
                pool-minsize="2"
                pool-maxsize="200"/>
    </datasource>
192.192.192.182是局域网服务器IP
用OEM能够登陆它，但到本地服务器就报错,请高手指教
