Buffalo不支持数组参数传递，还是我的写法有误

Step 1 用JS获取一组CHECKBOX的数组：
----------------------------------------------------------------------------------------------------------------------------------------------
var selectedFiles = document.getElementsByName("fileIds");
for(var i =0 ; i < selectedFiles.length; i++){
if (selectedFiles[i].checked){
alert(selectedFiles[i].value); //值完全正确
}
}
----------------------------------------------------------------------------------------------------------------------------------------------
Step 2 将数组传递给JAVA服务：发生页面错误提示，实际上Call function失败，因为Step3 的Service工作正常，没有
Call到。
----------------------------------------------------------------------------------------------------------------------------------------------
buffalo.remoteCall("baseService.deleteBaseFile",[selectedFiles],
function(reply){
var k=reply.getResult();
}）；
----------------------------------------------------------------------------------------------------------------------------------------------
Step 3 JAVA服务代码：
----------------------------------------------------------------------------------------------------------------------------------------------
public int deleteBaseFile(String[] fileIds){
System.out.println("Here is deleteBaseFile function");
return baseDao.deleteBaseFile(fileIds);
}
----------------------------------------------------------------------------------------------------------------------------------------------

selectedFiles是一个对象，selected.value才是string值

问题是如何把JS的数组对象（如例子中的selectedFiles)传递给JAVA方法中的数组对象？
例子中数组对象的值已经可以通过"alert(selectedFiles[i].value); //值完全正确 "验证说明取到了呵，只是传
给ＪＡＶＡ方法的时候，报错。

var extractedStrings = selectedFiles.collect(function(el){return el.value});

<input type="checkbox" name="fileIds" id="fileIds" value="11">
<input type="checkbox" name="fileIds" id="fileIds" value="12">
<input type="checkbox" name="fileIds" id="fileIds" value="13">
<input type="checkbox" name="fileIds" id="fileIds" value="14">
运行：var selectedFiles = document.getElementsByName("fileIds"); 之
后，selectedFiles是一个对象。

var extractedStrings = selectedFiles.collect(function(el){return

el.value}); 这样会报JavaScript错。
var extractedStrings = [11,12,13,14].collect(function(el){return
el.value}); 可以得到：extractedStrings = 11,12,13,14
如果将extractedStrings = 11,12,13,14传给JAVA方法，也会页面错误，也就是说类型不匹配。尝试如下：
如果后工拼出一个extractedStrings = [11,12,13,14] ，JAVA也会报错，数组对象不匹配：cannot find
the method deleteBaseFile(java.lang.String[[11,12,13,14]]) for com.
如果后工拼出一个extractedStrings = 11,12,13,14，JAVA也会报错，数组对象不匹配：cannot find
the method deleteBaseFile(java.lang.String[11,12,13,14]) for
com..................BaseService
如果后工拼出一个extractedStrings = {11,12,13,14} ，JAVA也会报错，数组对象不匹配：cannot find
the method deleteBaseFile(java.lang.String[{11,12,13,14}]) for
com................BaseService
