    <p>I am using ksoap2 to call the java webservice in Android. Java Web service method is,</p> <p>ImageProcessImpl.java</p> <pre><code>public UserResponse sample(UserRequest userRequest) { return ImageProcessDAO.sample(userRequest); } </code></pre> <p>ImageProcessDAO.java</p> <pre><code>public static String sample(UserRequest userRequest) { System.out.println(userRequest.getClientName()); UserResponse UserResponse = new UserResponse(); userResponse.setMessage("SUCCESS"); return userResponse; } </code></pre> <p>I am calling these webservices from Android as,</p> <pre><code>try{ String NAMESPACE = "http://impl.test.com"; String URL = "http://10.0.2.2:8080/Webservice/services/ImageProcessImpl?wsdl"; String SOAP_ACTION = "http://impl.test.com/sample"; String METHOD_NAME = "sample"; SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); UserRequest userRequest = new UserRequest(); userRequest.setClientName("Test"); PropertyInfo pi = new PropertyInfo(); pi.setName("userRequest"); pi.setValue(userRequest); pi.setType(UserRequest.class); request.addProperty(pi); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); envelope.implicitTypes = true; envelope.addMapping(NAMESPACE, "UserResponse", UserResponse.class); AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL); httpTransport.debug = true; httpTransport.call(SOAP_ACTION, envelope); UserResponse response = (UserResponse) envelope.getResponse(); Log.e(Test.LOG_TAG, response.getMessage()); }catch (Exception e) { Log.e(Test.LOG_TAG, "throws an exception: " + e.getMessage()); } </code></pre> <p>But I am getting the error in my Logcat is "<strong>throws an exception: Cannot serialize: com.test.common.UserRequest</strong>". How to fix this error? Is this right way to call web service with complex type?</p> <p>my wsdl file is,</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;wsdl:definitions targetNamespace="http://impl.test.com" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://impl.test.com" xmlns:intf="http://impl.test.com" xmlns:tns1="http://common.test.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt; &lt;!--WSDL created by Apache Axis version: 1.4 Built on Apr 22, 2006 (06:55:48 PDT)--&gt; &lt;wsdl:types&gt; &lt;schema elementFormDefault="qualified" targetNamespace="http://impl.test.com" xmlns="http://www.w3.org/2001/XMLSchema"&gt; &lt;import namespace="http://common.test.com"/&gt; &lt;element name="sample"&gt; &lt;complexType&gt; &lt;sequence&gt; &lt;element name="userRequest" type="tns1:UserRequest"/&gt; &lt;/sequence&gt; &lt;/complexType&gt; &lt;/element&gt; &lt;element name="sampleResponse"&gt; &lt;complexType&gt; &lt;sequence&gt; &lt;element name="sampleReturn" type="tns1:UserResponse"/&gt; &lt;/sequence&gt; &lt;/complexType&gt; &lt;/element&gt; &lt;/schema&gt; &lt;schema elementFormDefault="qualified" targetNamespace="http://common.test.com" xmlns="http://www.w3.org/2001/XMLSchema"&gt; &lt;complexType name="UserRequest"&gt; &lt;sequence&gt; &lt;element name="clientName" nillable="true" type="xsd:string"/&gt; &lt;/sequence&gt; &lt;/complexType&gt; &lt;complexType name="UserResponse"&gt; &lt;sequence&gt; &lt;element name="message" nillable="true" type="xsd:string"/&gt; &lt;/sequence&gt; &lt;/complexType&gt; &lt;/schema&gt; &lt;/wsdl:types&gt; &lt;wsdl:message name="sampleRequest"&gt; &lt;wsdl:part element="impl:sample" name="parameters"&gt; &lt;/wsdl:part&gt; &lt;/wsdl:message&gt; &lt;wsdl:message name="sampleResponse"&gt; &lt;wsdl:part element="impl:sampleResponse" name="parameters"&gt; &lt;/wsdl:part&gt; &lt;/wsdl:message&gt; &lt;wsdl:portType name="ImageProcessImpl"&gt; &lt;wsdl:operation name="sample"&gt; &lt;wsdl:input message="impl:sampleRequest" name="sampleRequest"&gt; &lt;/wsdl:input&gt; &lt;wsdl:output message="impl:sampleResponse" name="sampleResponse"&gt; &lt;/wsdl:output&gt; &lt;/wsdl:operation&gt; &lt;/wsdl:portType&gt; &lt;wsdl:binding name="ImageProcessImplSoapBinding" type="impl:ImageProcessImpl"&gt; &lt;wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/&gt; &lt;wsdl:operation name="sample"&gt; &lt;wsdlsoap:operation soapAction=""/&gt; &lt;wsdl:input name="sampleRequest"&gt; &lt;wsdlsoap:body use="literal"/&gt; &lt;/wsdl:input&gt; &lt;wsdl:output name="sampleResponse"&gt; &lt;wsdlsoap:body use="literal"/&gt; &lt;/wsdl:output&gt; &lt;/wsdl:operation&gt; &lt;/wsdl:binding&gt; &lt;wsdl:service name="ImageProcessImplService"&gt; &lt;wsdl:port binding="impl:ImageProcessImplSoapBinding" name="ImageProcessImpl"&gt; &lt;wsdlsoap:address location="http://localhost:8080/Webservice/services/ImageProcessImpl"/&gt; &lt;/wsdl:port&gt; &lt;/wsdl:service&gt; &lt;/wsdl:definitions&gt; </code></pre> <p>I used the KvmSerializable. I have added one more array bean variable <code>private Client[] clientNameList = null;</code> in UserRequest.java. </p> <p>When I call the web service it is working fine in the request. But in the response I am getting one string that contains all values. The response string is given below.</p> <p><code>anyType{clientNameList=anyType{clientNameList=anyType{clientID=1; }; clientNameList=anyType{clientID=2; }; }; message=SUCCESS; }.</code> </p> <p>How Can I parse this string?</p> <p>UserResponse.java</p> <pre><code>public class UserResponse implements KvmSerializable{ public String message = null; public Client[] clientNameList = null; @Override public Object getProperty(int index) { switch (index){ case 0: return message; case 1: return clientNameList; default: return null; } } @Override public int getPropertyCount() { // TODO Auto-generated method stub return 2; } @Override public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) { switch(index) { case 0: info.type = PropertyInfo.STRING_CLASS; info.name = "message"; break; case 1: info.type = PropertyInfo.OBJECT_TYPE;

break; default: break; } } } </code></pre> <p>Client.java contains only clientId of Integer type.</p> <p><strong>Updated code and wsdl</strong> </p> <p>ImageProcessImpl.java</p> <pre><code>public UserResponse sample(UserRequest userRequest) { return ImageProcessDAO.sample(userRequest);

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
