我使用Apache的ofbiz的，03年7月13日。我構建項目，螞蟻。我改變了數據庫mysql.When我想加載種子/演示數據或螞蟻啓動，日誌顯示錯誤。Ofbiz中：無法建立與數據庫的連接的helperName [localmysql]
***我使用MySQL連接器的Java-5.1.40-bin.jar JDBC連接

我entityengin.xm就像
<delegator name="default" entity-model-reader="main" entity-group-reader="main" entity-eca-reader="main" distributed-cache-clear-enabled="false">
<group-map group-name="org.ofbiz" datasource-name="localmysql"/>
<group-map group-name="org.ofbiz.olap" datasource-name="localmysqlolap"/>
<group-map group-name="org.ofbiz.tenant" datasource-name="localmysqltenant"/>
</delegator>
而我localmysql部分
在我的服務器的ip是10.0.31.8
我想分享，我可以成功地運行在我的本地機器上這個項目，而無需任何問題

請檢查您的數據庫用戶和權限設置。您可以從錯誤中看到，用戶ofbiz不允許從IP 10.0.31.110訪問您的數據庫。 如需進一步調查，請提供您的相關entityengine.xml設置。 –
@MichaelBrohl我在我的代碼的最後一部分添加了我的entityengin.xml代碼... 我可以通過命令窗口通過命令窗口登錄到我的mysql數據庫通過'**用戶名：ofbiz並傳遞：ofbiz **，因爲我給予ofbiz授予所有權限.. 非常感謝你 –
可能重複[Java JDBC訪問拒絕用戶]（http://stackoverflow.com/questions/8224898/java-jdbc-access-denied-for-user） –
