我正在使用 IBM MobileFirst Platform Studio（v6.3 - 前 IBM Worklight）开发混合应用程序。

由于需要调用包含 OUT 参数的 Oracle 存储的 PL/SQL 过程，因此我使用了此处提供的解决方案How to get OUT parameter when invoking a stored procedure？- 在 java 中调用存储过程并从适配器过程调用 java 类。

我将 StoredProcedure.java src 文件添加到我项目中的 server/java 文件夹中。我还将 commons-dbutils-1.6.jar 和 ojdbc6.jar 添加到 server/lib 文件夹。StoredProcedure 类建立在保存并部署在 MobileFirst Development 服务器上。我还在 server.xml 中定义了所需的数据源，但是当我尝试测试我实现的适配器过程时（R-单击适配器运行方式 -> 部署 MobileFirstAdapter，R-单击适配器运行方式 -> 调用 MobileFirst 过程）我收到此错误信息：

我还应该怎么做才能让后端服务找到 commons-dbutils-1.6.jar ？

我正在使用 64 位 Java v1.7.0.72 的 Windows 7 64 位上运行 Eclipse 版本：Luna Service Release 1 (4.4.1)，连接到 Oracle Server 11g。

在 server/lib 目录中删除必要的 jar 对我不起作用。我必须复制所需的 jars (dbutils) 和为调用存储过程而创建的自定义 jar，在 Eclipse 工作区中相对于 WorklightServerConfig 的以下目录中

<workspace>/WorklightServerConfig/shared/resources

映射到 server.xml 中的以下变量

${shared.resource.dir}

然后定义 oracle 库，我在名为 oracle 的子目录中有 ojdbc6.jar

<library id="ORACLE_LIB">
    <fileset dir="${shared.resource.dir}/oracle" includes="*.jar"/>
</library>

<connectionManager id="OraclePool" maxPoolSize="40" minPoolSize="10"/>

<dataSource id="mobileDatasource" jndiName="jdbc/mobile__datasource">
    <jdbcDriver libraryRef="ORACLE_LIB"/>
    <properties.oracle URL="jdbc:oracle:thin:@..." password="..." user="..."/>
</dataSource>
