I figure it out. This is solution: <wsdl:message name="getSubjectsRequest"> <part name="getSubjectsReq" type="xsd:string" /> </wsdl:message> <wsdl:message name="getSubjectsResponse"> <part name="getSubjectsReturn" type="tns:myarray"/> </wsdl:message> <wsdl:message name="getClassesRequest"> <part name="getClassesReq" type="xsd:string" /> </wsdl:message> <wsdl:message name="getClassesResponse"> <part name="getClassesReturn" type="tns:myarray"/> </wsdl:message> Request Messages can't be empty.

I have strange problem with SOAP. My file SchoolAPI look like that: <?php require_once('../require/constants.php'); require_once('../require/connection.inc.php'); class SchoolAPI{ private $dbh; public function __construct() { $this->dbh = new PDO(DRIVER.':host='.HOST.';dbname='.DB, USER, PASSWORD); } //function return all subcjects public function getSubjects(){ $sth = $this->dbh->prepare(' SELECT id, nazwa ROM subjects'); $sth->execute(); return $sth->fetchAll(PDO::FETCH_NUM); //return array(array("1", "subject1"),array("2", "subject2")); } //function return all classes public function getClasses(){ $sth = $this->dbh->prepare(' SELECT id, nazwa FROM classes'); $sth->execute(); return $sth->fetchAll(PDO::FETCH_NUM); //return array(array("1", "class1"),array("2", "class2")); } } ini_set("soap.wsdl_cache_enabled", "0"); $server = new SoapServer("SchoolAPI.wsdl"); $server->setClass("SchoolAPI"); $server->handle(); ?> wsdl file is named SchoolAPI.wsdl and look like that: <wsdl:definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://schema.example.com" targetNamespace="http://schema.example.com" > <wsdl:types> <xsd:schema targetNamespace="http://schema.example.com"> <xsd:complexType name="myarry2"> <xsd:sequence> <xsd:element minOccurs="0" maxOccurs="unbounded" name="row" nillable="true" type="xsd:string" /> </xsd:sequence> </xsd:complexType> </xsd:schema> <xsd:schema targetNamespace="http://schema.example.com"> <xsd:complexType name="myarray"> <xsd:sequence> <xsd:element minOccurs="0" maxOccurs="unbounded" name="table" nillable="true" type="tns:myarry2" /> </xsd:sequence> </xsd:complexType> </xsd:schema> </wsdl:types> <wsdl:message name="getSubjectsRequest"></wsdl:message> <wsdl:message name="getSubjectsResponse"> <part name="getSubjectsReturn" type="tns:myarray"/> </wsdl:message> <wsdl:message name="getClassesRequest"></wsdl:message> <wsdl:message name="getClassesResponse"> <part name="getClassesReturn" type="tns:myarray"/> </wsdl:message> <wsdl:portType name="SchoolAPIPortType"> <wsdl:operation name="getSubjects"> <wsdl:input message="tns:getSubjectsRequest"/> <wsdl:output message="tns:getSubjectsResponse"/> </wsdl:operation> <wsdl:operation name="getClasses"> <wsdl:input message="tns:getClassesRequest"/> <wsdl:output message="tns:getClassesResponse"/> </wsdl:operation> </wsdl:portType> <wsdl:binding name="SchoolAPIBinding" type="tns:SchoolAPIPortType"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="getSubjects"> <soap:operation soapAction="urn:SchoolAPI/getSubjects" style="document"/> <wsdl:input> <soap:body use="literal"/></wsdl:input> <wsdl:output><soap:body use="literal"/></wsdl:output> </wsdl:operation> <wsdl:operation name="getClasses"> <soap:operation soapAction="urn:SchoolAPI/getClasses" style="document"/> <wsdl:input> <soap:body use="literal"/></wsdl:input> <wsdl:output><soap:body use="literal"/></wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="SchoolAPI"> <wsdl:port name="SchoolAPIPort" binding="tns:SchoolAPIBinding"> <soap:address location="http://localhost:82/myschool/webservices/SchoolAPI.php" /> </wsdl:port> </wsdl:service> </wsdl:definitions> The problem is that correct data is returned olny by first function declarated in <wsdl:binding> section. In this example correct data will be return by getSubjects function, and function getClassses return null. However, if we change order and put getClasses operation first in binding section like this: <wsdl:binding name="SchoolAPIBinding" type="tns:SchoolAPIPortType"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="getClasses"> <soap:operation soapAction="urn:SchoolAPI/getClasses" style="document"/> <wsdl:input> <soap:body use="literal"/></wsdl:input> <wsdl:output><soap:body use="literal"/></wsdl:output> </wsdl:operation> <wsdl:operation name="getSubjects"> <soap:operation soapAction="urn:SchoolAPI/getSubjects" style="document"/> <wsdl:input> <soap:body use="literal"/></wsdl:input> <wsdl:output><soap:body use="literal"/></wsdl:output> </wsdl:operation> </wsdl:binding> then correct data will be return by getClasses function, and getSubjects will return null. Do you know what is going on? I do my best to solve this problem and I have no idea what is wrong...
