因为没遇到过Array类型。处理有些困难，望大虾帮帮忙，帮看看怎么处理？[/size]

Answer 1

试过很多但未果。问题主要出在array传参上，现在也可以调用，也有返回值，但并不是真正的结果。
上面代码返回是全部数据，array那个参数并没有传递进入。array中有参数['new','open'...],通过java调用perl完成的webservice项目，并得到相应的返回数据。如果哪个大侠明白，请多指点！

Answer 2

这个，得看wsdl文件中对返回值的定义

Answer 3

前面问题已解决：原程序调用方法： 
StateType => $['new','open'] dispatch.addChildElement("Param2_Name").addTextNode("StateType").setAttribute("xsi:type","xsd:string"); 
SOAPElement e = dispatch.addChildElement("Array", "enc"); 
e.setAttribute("enc:arrayType", "xsd:string[2]"); 
e.setAttribute("xsi:type", "enc:Array"); 
e.addChildElement("item").addTextNode("new").setAttribute("xsi:type", "xsd:string"); 
e.addChildElement("item").addTextNode("open").setAttribute("xsi:type", "xsd:string"); 后有又有问题，但已解决，分享下：
原程序调用方法： 
Attachment => [ 
            { 
                Content     => $Content, 
                ContentType => $ContentType, 
                Filename    => 'lala.txt', 
            }, 
            { 
                Content     => $Content, 
                ContentType => $ContentType, 
                Filename    => 'lala1.txt', 
            }, 
        ], 
解决方法：
Filename，ContentType，Content分别为传入的上传附件的参数；Content为附件转换成base64Binary种字符串； 
当对象为多个时需要调整xsd:anyType[n]的数量； 
dispatch.addChildElement("Param19_Name").addTextNode("Attachment").setAttribute("xsi:type","xsd:string"); 
SOAPElement e = dispatch.addChildElement("Array", "enc"); 
e.setAttribute("enc:arrayType", "xsd:anyType[1]"); 
e.setAttribute("xsi:type", "xsd:Array"); 
SOAPElement obj = e.addChildElement("item"); 
e.addChildElement(obj); 
obj.addChildElement("Filename").addTextNode(Filename).setAttribute("xsi:type","xsd:string"); 
obj.addChildElement("ContentType").addTextNode(ContentType).setAttribute("xsi:type","xsd:string"); 
obj.addChildElement("Content").addTextNode(Content).setAttribute("xsi:type","xsd:base64Binary"); 
e.addChildElement(obj);
