Worklight 6.2中的DB2 SQL语句（SQL适配器）

我要求求助，我在工作中相对较新，我必须开发一个与DB2数据库通信的程序。 我正在使用Worklight 6.2和DB2 express-c 10.5.1，我希望得到这个标准的结果：

var procedure1Statement = WL.Server.createSQLStatement("SELECT location FROM ORG;");
function procedure1(param) {
    return WL.Server.invokeSQLStatement({
        preparedStatement : procedure1Statement,
        parameters : [param]
    });
}

设置我的SQL适配器：

<wl:adapter name="DB2Adapter"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:wl="http://www.worklight.com/integration"
    xmlns:sql="http://www.worklight.com/integration/sql">

    <displayName>DB2Adapter</displayName>
    <description>DB2Adapter</description>
    <connectivity>
        <connectionPolicy xsi:type="sql:SQLConnectionPolicy">
        <dataSourceDefinition>
            <driverClass>com.ibm.db2.jcc.DB2Driver</driverClass>
            <url>jdbc:db2://localhost:50000/sample</url>
            <user>Ondra</user>
            <password>OndraPass</password>  
            </dataSourceDefinition>
        </connectionPolicy>
        <loadConstraints maxConcurrentConnectionsPerNode="5" />
    </connectivity>
    <procedure name="procedure1"/>
    <procedure name="login" securityTest="LDAPAdapter-securityTest"/>

</wl:adapter>

我已将.jar文件复制到服务器lib文件夹（db2cc_license_cu.jar，db2cc.jar）

如果我尝试通过eclipse一个receve语句来调用worklight过程：

{
   "errors": [
      "Runtime: DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=;;CT location FROM ORG;END-OF-STATEMENT, DRIVER=3.66.46.\nPerformed query:\nSELECT location FROM ORG;"
   ],
   "info": [
   ],
   "isSuccessful": false,
   "warnings": [
   ]
}

在eclipse控制台中是：

{[AUDIT   ] CWWKG0016I: Starting server configuration update.
[AUDIT   ] CWWKG0018I: The server configuration was not updated. No functional changes were detected.
[ERROR   ] FWLSE0099E: An error occurred while invoking procedure  [project DataPower]DB2Adapter/SqlStatementFWLSE0100E:  parameters: [project DataPower]

有人可以帮我吗？我有点迷失

解决方案是删除';'在SQL语句中而不是在IBM教程中
