从ftp网关返回没有文件

我正在尝试从ftp目录中获取所有文件。我的配置：

<bean id="ftpSessionFactory"
    class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
    <property name="host" value="ftp.aaaaaa.bb"/>
    <property name="port" value="21"/>
    <property name="clientMode" value="2"/>
    <property name="username" value="XXXXXXX"/>
    <property name="password" value="YYYYYYY"/>
</bean>

<int:channel id="inbound"/>

<int:inbound-channel-adapter channel="inbound" expression="'GB2AV'">
    <int:poller fixed-rate="10000"/>
</int:inbound-channel-adapter>

<int-ftp:outbound-gateway id="gatewayLS"
    session-factory="ftpSessionFactory"
    request-channel="inbound"
    command="ls"
    command-options="-1"
    filename-pattern="*"
    remote-file-separator="\"
    expression="payload"
    reply-channel="outbound">
</int-ftp:outbound-gateway>

<int:channel id="outbound"/>

<int-stream:stdout-channel-adapter channel="outbound" append-newline="true"/>

它对我自己的测试服务器（Ubuntu / vsftp）非常有用。对于生产服务器（未知的操作系统和ftp服务器），我无法获取文件名。调试输出：

手动连接到ftp服务器时，我可以使用cd GB2AV更改目录，并使用ls显示此目录中的所有文件。我也尝试过各种文件分隔符等组合。

使用org.apache.commons.net.ftp.FTPClient时，我必须使用.listNames()返回String[]而不是.listFiles()，这会在我的情况下返回一个空对象。

我可以在网关配置中做些什么，还是听起来像服务器端缺少功能支持？
