Testing a secured webservivce in SOAP UI - web-services

I am using AXIS2 framework for my webservices creating. Now I am secured my webservices using ramprt. Now entire requests and response will be signed and encrypted.
Now my doubt is how can i test it in SOAP UI. when I am loading wsdl file it giving me as
below.
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soapenvelope"
xmlns:sam="http://sample03.policy.samples.rampart.apache.org">
<soap:Header/>
<soap:Body>
<sam:echo>
<!--Optional:-->
<sam:args0>?</sam:args0>
</sam:echo>
</soap:Body>
</soap:Envelope>
Now Ho w can i place digital certificate related data and how can i encrypt the content i want to send to axis server.
Thanks,
Narendra


the certificate data is stored in two xml Files the Outflowsecurity.xml and Inflowsecurity.xml they should look like this:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="action">

for more details go to the Apache help Page
To use the authentification in the Request you need to add a Tag to the soap:Header
<soapenv:Header>
<wsse:Security
soapenv:mustUnderstand="1">
<wsu:Timestamp
wsu:Id="Timestamp-31497899">
<wsu:Created>2008-02-06T13:39:50.943Z</wsu:Created>

<wsse:Username>apache</wsse:Username>
<wsse:Password
Type="http://...#PasswordText">password</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
the namespaces are:

Parse soap msg with gSOAP

I have following example xml message:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<to>...</to>
<from>...</from>
<id>..</id>
<relatesTo>...</relatesTo>

<version>...</version>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<customComplexElement>
<a>a_v</a>

<c>c_v</c>
<d>d_v</d>
<e>e_v</e>
<f>f_v</f>
</customComplexElement>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
From which I have generated a xsd file with use of one of online tools:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" attributeFormDefault="unqualified" elementFormDefault="qualified">
<import namespace="http://schemas.xmlsoap.org/soap/envelope/" schemaLocation="http://schemas.xmlsoap.org/soap/envelope/"></import>
<xs:element name="to" type="xs:string"/>
<xs:element name="from" type="xs:string"/>
<xs:element name="id" type="xs:string"/>
<xs:element name="relatesTo" type="xs:string"/>
<xs:element name="action" type="xs:string"/>
<xs:element name="version" type="xs:string"/>
<xs:element name="customComplexElement">
<xs:complexType>
<xs:sequence>
<xs:element type="xs:string" name="a"/>
<xs:element type="xs:string" name="b"/>
<xs:element type="xs:string" name="c"/>

<xs:element type="xs:string" name="e"/>
<xs:element type="xs:string" name="f"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Then I generate the appropriate header file with wsdl2h.exe and then compile it with soapcpp2.exe compiler.
Then I try to read xml file with a function soap_read_customComplexElement() and all I get is SOAP_TAG_MISMATCH. This method seems to work if I get rid of all the soap stuff the message but I wonder if there are some functions in gSOAP to parse soap envelope, header and body?

I've had same problem. But i've just fixed it.
So, in my case i use this line of code.
struct soap *soap = soap_new1(SOAP_C_UTFSTRING | SOAP_XML_IGNORENS | SOAP_XML_TREE);
The key paramter is SOAP_XML_IGNORENS. This parameter ignore namespaces.
SOAP_XML_IGNORENS in: ignores the use of XML namespaces in input
The root of this problem is that you don't declare namespaces in your body content. That why gSoap don't know how to convert this xml.
This wouldn't be converted, because gSoap don't know what is ns4:
<ns4:ParseKeywords><ns4:Keyword>Hello</ns4:Keyword></ns4:ParseKeywords>
But if i declare namespace it will be converted
<ns4:ParseKeywords xmlns:ns4="com.idurdyev.idcommerce:ParseKeywords:1.0"><ns4:Keyword>Hello</ns4:Keyword></ns4:ParseKeywords>

My first try was follow a POJO model how ever i did not have any success. I couldnt reproduce the <xs:choice minOccurs="0" maxOccurs="unbounded">. So i am here to ask for an idea to create a soap web service that follows this schema.
best regards,

Why don't you use the xjc tool which comes with your JDK and creates the required jax-b artifacts from a xsd...
something like this will create the classes in the 'generated' subfolder of the current directory:
xjc /the/path/to/my/xsdfile.xsd
Also look here: http://docs.oracle.com/javase/6/docs/technotes/tools/share/xjc.html

Primary and foreign keys in xml schema

I am trying to insert primary and foreign keys in XSD schema file below :-
Primary key is StudentID and Foreign Keys are courseID, AddressID, GradeID.
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Student">
<xs:complexType>
<xs:sequence>
<xs:element name="Title" type="xs:string"/>
<xs:element name="FirstName" type="xs:string"/>
<xs:element name="LastName" type="xs:string"/>
<xs:element name="Dateborn" type="xs:date"/>
<xs:element name="Gender" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
However above code is not working in my setup please help me in tracing the issue,

In general you would need to put more details in a question... So this should be enough to understand what else you might need to define, and how. I'll tackle what's needed to understand how to define a primary key/foreign key by illustrating an assumed student/address relationship.
First you need to define a context where these constraints hold true. In my modified XSD, I call it the "World".
<?xml version="1.0" encoding="utf-8" ?>
<!-- XML Schema generated by QTAssistant/XSD Module (http://www.paschidev.com) -->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="World">
<xs:complexType>
<xs:sequence>
<xs:element ref="Student" maxOccurs="unbounded"/>
<xs:element ref="Address" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:key name="PKStudents">
<xs:selector xpath="Student/StudentID"/>
<xs:field xpath="."/>
</xs:key>
<xs:key name="PKAddresses">
<xs:selector xpath="Address/AddressID"/>
<xs:field xpath="."/>
</xs:key>
<xs:keyref name="FKStudentToAddress" refer="PKAddresses">
<xs:selector xpath="Student/AddressID"/>
<xs:field xpath="."/>
</xs:keyref>
</xs:element>
<xs:element name="Student">
<xs:complexType>
<xs:sequence>
<xs:element name="Title" type="xs:string"/>
<xs:element name="FirstName" type="xs:string"/>
<xs:element name="LastName" type="xs:string"/>
<xs:element name="Dateborn" type="xs:date"/>
<xs:element name="Gender" type="xs:string"/>
<xs:element name="StudentID" type="xs:string"/>
<xs:element name="AddressID" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="Address">
<xs:complexType>
<xs:sequence>
<xs:element name="AddressID" type="xs:string"/>
<xs:element name="Street" type="xs:string"/>
<xs:element name="City" type="xs:string"/>
<xs:element name="Province" type="xs:string" minOccurs="0"/>
<xs:element name="Country" type="xs:date" minOccurs="0"/>
<xs:element name="PostalCode" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Then an XML like this would pass or fail, depending on what you do with the values in the StudentID and AddressID fields.
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<!-- Sample XML generated by QTAssistant (http://www.paschidev.com) -->
<World xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Student>
<Title>Title1</Title>
<FirstName>FirstName1</FirstName>
<LastName>LastName1</LastName>
<Dateborn>1900-01-01</Dateborn>
<Gender>Gender1</Gender>
<StudentID>StudentID1</StudentID>
<AddressID>AddressID1</AddressID>
</Student>
<Student>
<Title>Title1</Title>
<FirstName>FirstName1</FirstName>
<LastName>LastName1</LastName>
<Dateborn>1900-01-01</Dateborn>
<Gender>Gender1</Gender>
<StudentID>StudentID2</StudentID>
<AddressID>AddressID1</AddressID>
</Student>
<Address>
<AddressID>AddressID1</AddressID>
<Street>Street1</Street>
<City>City1</City>
<Province>Province1</Province>
<Country>1900-01-01</Country>
<PostalCode>PostalCode1</PostalCode>
</Address>
<Address>
<AddressID>AddressID2</AddressID>
<Street>Street1</Street>
<City>City1</City>
<Province>Province1</Province>
<Country>1900-01-01</Country>
<PostalCode>PostalCode1</PostalCode>
</Address>
</World>
To finish your solution, you would need to define the Course and Grade "entities" in your "world", define the xs:key for each, similar to Student/*Address*, then add CourseID and GradeID attributes to the entities that need them, and finally, define the keyref, as above, for Entity to Grade and Entity to Course.

So far I have been able to read the webservice, here is the code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Try
Dim SerSyncfonia As Syncfonia.Productos
SerSyncfonia = New Syncfonia.Productos()
Dim v1 = "7505000010064"
Dim v2 = "DISTRIBU"
Dim v3 = "DISTRIBU"
Dim v4 = ""
Dim v5 = "7500112045058"
Label1.Text = SerSyncfonia.ObtieneProducto(v1, v2, v3, v4, v5).ToString
Catch ex As Exception
Label1.Text = ex.Message.ToString
End Try
End Sub
The result I'm getting for Label1.Text after pressing Button1 is "System.Data.DataSet"
So, after I read the Web Service, how can I store this data somewhere to be able to work with data. For example, get the value of the nombregen element, or gtin element and store them somewhere.

In general, it's a bad idea to pass the DataSet class or any other type specific to .NET when using web services. That makes them only usable by compatible versions of .NET (not Java, for instance).
In your case, though, there's a simpler question: even if a DataSet was successfully passed, what exactly did you expect the ToString method to do? Even without web services, DataSet.ToString() isn't going to produce useful output.
