Consuming web services with a java application

Hello,
I want to consume an ABAP generated web service with a stand-alone Java application. I am very new to this topic and need some hints how this functionality could be achieved.
How is the web service accessed by the Java application? What about security issues?
Thank you in advance for your replies! They will be appreciated.
Kindest regards

Biztalk 2010 - Consume Web Service with Certificate

Hi
I have to consume a java web service with Biztalk that requires authentication via a client certificate. Until now I have not been able to consume any web service where any kind of authentication was needed. Simple web services without authentication are
no problem. Also using SoapUI works perfectly fine.
I am generating the XSDs and the port binding with the WCF wizard in VS2010. I've read several comments that it's not possible to consume web services with the WCF-WSHttp adapter when the message format should be SOAP 1.1. Therefore I'm trying with the WCF-BasicHttp
and WCF-Custom adapters, but I did not suceed in receiving a positive response yet.
The web service I want to consume uses a client certificate (with a private key) and two root certificates. When I use the BasicHttp adapter I choose either 'Transport' or 'TransportWithMessageCredential' but none of them work. I also have to supply a client
and a service certificate. I always use the one with the private key for the client but I'm not sure which one I have to use for the service. Is there a possibility that I have to provide both root certificates and if so, how can I achieve this?
Hope the question makes sense somehow... thanks for any input.
Error message that I receive currently is that the server needs a client certificate. However I attached it in the send port properties under the tab "Security" => mode "TransportWithMessageCredential".

Adapter: WCF-Custom
Binding: customBinding
Cannot send pictures (yet).

Error consuming Web service with object hierarchy

I am creating a Web reference to a Web service deployed on JBoss application server. Incidentally, I am able to consume this Web service and run a client against it in .NET. Sun Java Studio Creator has a problem with one of methods in my Web service.
As far as I can tell from my experimentation, the problem lies in the fact that the JavaBean returned from the Web service extends another JavaBean (rather than Object). When I flatten the value object in question, I am able to run the same Web service method in Studio Creator.
I encountered the following post on this forum: http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=49056. It appears to describe a similar problem. I tried to follow the instructions in that forum by upgrading the JWSDP version (to 1.5) to no avail. I continue to receive the following error when trying to test the Web Service method after creating a Web Service reference in Creator.
The relevant error appears to be
deserialization error: deserialization error: unexpected XML reader state. expected: END but found: START: entityID (where entityID is one of the attributes of the object being returned by the Web Service, which is defined in that object's parent class).

Consuming web services with Attachments

Hello,
I need to consume a web service with attachements (mime type) from sap was j2ee 7.0 (nw2004s).
When I try to generate the web service deployable proxy using nwds (version 7.0.06), I get the following error message
"Invalid WSDL or WSDL not found, please specify different WSDL.."
Removing references to"wsi:swaRef" from wsdl, above error is not displayd and wsdl is correctly processed
<complexType name="ArrayOf_tns2_swaRef">
- <sequence>
<element maxOccurs="unbounded" minOccurs="0" name="swaRef" nillable="true" type="wsi:swaRef" />
</sequence>
</complexType>
Unfortunately, we have not been able to find any SAP documentation (online help, oss note,,,) describing if SAP WAS Java 7.0 supports this standard.
Has anybody already worked with Web Services with attachments ?
Thanks in advace,
Regards
Berta

Consuming Web Services with ABAP - WSDL

Hi All,
I Want to consume web service in abap, i found lot of documents,Here i am having data in the internal table i need to pass
it to wsdl file, The Web Service or Proxy generates a WSDL file. So this WSDL file can be consumed on ABAP Front and Encrypt the Data that is to be sent to the Banks.
I found the input and output, Where i can find the method generated or we need to create it
CALL METHOD io_clientproxy->XXXXXXXXXXXX
please let me have your valuable ideas
Thanks in advance,

Hi Miguel,
I have not heared about SPROXY, Here i found some code,which calls a web service method and where it is from.
when i double click on my proxy it shows me some method.IF_PROXY_BASIS_INTERNAL~CREATE_FRAMEWORK

Web service with complex java type

Hi,
I create a web service method with String o with Array of Strings without problem. Now I nedd to create a ws that return a table, so I create a class like this:
public class User {
     private String Name;
     private String.Surname;
     public void setName(String setName){
          Name= setName;
     public void setSurname(String setSurname){
          Surname=setSurname;
In my ws class I use this object:
public User[] getUser(String a){
          User[] user = new User[10];
          for (int i=0;i<10;i++){
               User<i>.setName("aaa");
               User<i>.setSurname("bbb");
          return user;
When in WebService Perspective I try to create my ws in wizard mode I see method getUser but I can't check it
Where is error?
Thanks
Andrea

HI Andrea,
    I think with present netweaver developer studio , we can create Web services with end points as simple data types in java and the array of that simple data types.
    not sure whether it support our own custom developed classes as end points.
     just go through these links.
http://help.sap.com/saphelp_nw2004s/helpdata/en/f7/af60f2e04d0848888675a800623a81/frameset.htm
http://help.sap.com/saphelp_nw2004s/helpdata/en/f7/af60f2e04d0848888675a800623a81/frameset.htm
from this we will get Restrictions for WS Endpoints.

How to create password digest from PLSQL? or if any other alternatives available please response soon.

I do not see why it will not be possible to do digest authentication with a web server using PL/SQL.
As for the digest password - the web server supplies a token (a nonce) which you need to use for creating the hashed authentication token (the digest password). The URL I posted explains this authentication process.
As for the technical how-to in PL/SQL - as I mentioned, never had to do this (only dealt with Basic and NTLM authentication thus far). But as other auth methods (such as Microsoft's NTLM) can be implemented, I do not see why digest authentication could not.
Suggest you spend some time googling for technical articles/sample code on the subject - and try to find specific PL/SQL related sample code too.

Problem consuming web service with basic authentication

Hello,
I've set up a web service with basic authentication. Although I have to log in before being able to open the overview page of the web service in the Web Service Navigator, the response I get after sending a request is:
Authority check failed
I get this response in the Web Service Navigator as well as when consuming the web service via standalone proxy classes.
The following is strange, too: It is not possible to change authentication in the generated logical port. It is set to "none". I changed it via the XML file where I added the properties "AuthenticationMethod" (value "BasicAuth") and "AuthenticationMechanism" (value "HTTP"). But I got the above response anyway.
Thanks for your help!
Regards

I used basic authentication for my web service.
I was able to obtain a hardcopy of the logfiles in the meantime. The invocation of the web service is stored there with the following error messages:
<i>SOAP Runtime: Exception message: Schwerer Prozessierungsfehler macht eine SOAP-Fault-Behandlung erforderlich
SOAP Runtime: SOAP Fault exception occurred in program CL_SOAP_RUNTIME_SERVER========CP in include CL_SOAP_RU NTIME_SERVER... [the picture is cut here]</i>
In addition to that I found a thread in SDN that dealt with exactly the same problem:
Web Service Homepage: Authority check failed
But I have the same problem like Kimberly Carmack (the last post on the second page). We do not have that role in our system.

Invoking a AXIS Web Service with a Java object as input argument

Hi
I've been trying to execute a bpel process that invokes a web service deployed through axis.
This web service takes a java object as input argument as opposed to data types that are directly mapped to java types through the SOAP engine.
I deployed and tested the service outside of BPEL using a test client class. Everything works well.
When I try to configure the "Assign" and "Invoke" activities so that service can be invoked, I cannot see the data structure through the variable picker and I see the following message:
"The element {urn:ComplexTypeWebService}TimeSheetBean is not know to the schema container. Perhaps a schema file that uses it needs to include or import its definition.There mat also be an XML schema issue (non resolvable schema) which prevents {urn:ComplexTypeWebService}TimeSheetBean from being seen by the schema processor."
Is there any example that demonstrates how to invoke an axis web service in such scenario? What am I doing wrong?
Please, let me know.

The passing of Java objects in and out of a web service is NOT supported. variables must be xml documents defined by a XML schema. In my opinion, missing Java object and WSDL is not a good idea. -Edwin

Consuming a web service with a java client

hello
wanted to consume the following web service:
http://www.dataaccess.com/webservicesserver/numberconversion.wso
http://www.dataaccess.com/webservicesserver/numberconversion.wso?op=NumberToWords
so i used WSDL2Java to create client stubs n then followed it with a client program
public class XmethodsAccessor {
public static void main(String[] args) throws Exception{
org.apache.axis2.databinding.types.UnsignedLong x = new org.apache.axis2.databinding.types.UnsignedLong(10000L);
NumberConversionStub stub = new NumberConversionStub();
NumberConversionStub.NumberToWords request = new NumberConversionStub.NumberToWords();
request.setUbiNum(x);
NumberToWordsResponse response = stub.NumberToWords(request);
System.out.println("answer is : " + response.getNumberToWordsResult());
Upon running the program i get error

Consuming Web Services with Web Dynpro Java

Hi All,
I've been searching around for a weblog that would describe building a web dynpro java app that consumes a web service. Ideally, I'm looking for something that has at least two views.
Does anyone know of good weblogs that address this?
Thanks!
Roman D.

Have a look at the https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro?rid=/webcontent/uuid/5b77db42-0a01-0010-d7ba-8aa375593dd3">tutorial [original link is broken] [original link is broken].

Consuming web services with JDeveloper

Hi everyone, Im trying to consume a web service from an Oracle database 9.2.0.6, which has Java 1.3.1. I started using JDeveloper 10.1.2 with sdk 1.4, but when ever I tried to deploy into the database a bunch of libraries had to be pointed in order to successfully load it into the database, and besides it never worked.
I assumed that it was for the java versions, since in the database I have an older one. I then downloaded java 1.3.1 in my PC and when I compiled my code (defining a 1.3.1 profile before to point to javaw in 1.3.1 version) but when I tried to execute I get the error (Unsupported major.minor version 48.0). I read that this happens according to the VM version.
I decided to move then to JDeveloper 9i, but when creating my stub and uploading it to the database, it keeps asking to add libraries which some of them I don't know where are (oracle/bali, oracle/jsp..etc)
What do I need to generate my stub correctly and then deploying it to database? What versions for Jdev and Java SDK do I need to get it working correctly?

One solution to this problem is to make sure that the complex type you are using in yous service interface do implement the JAVA Bean as per the spec (at least Oracle's interpretation of it).
You need to have getter/setter for all members and you need to have an empty ctor() to create new instances of your objects. In some cases, the design time let you get by, but the runtime fails in the code generation.
In your case, the 'Task' class may have some issue.
Hope it helps,

Consuming web service with with a custom class parameter in web dynpro

Hi,
I have developed a web service. It is tested an it runs fine. The webservice is retrieving and returning Data Transfer Objects (POJOS). I have made the model-context binding, then the view controller - component controller binding with the input parameters for one method of the web service.
In an input field I have set the value to a attribute of the DTO. (This appears: Request_CreateProductGroup.CreateProductGroup.ProductGroupDTO.CompText)
When I run the Application I get following error:
com.sap.tc.webdynpro.model.webservice.base.exception.BaseModelRuntimeException: No object for mandatory target role 'ProductGroupDTO' of model class 'CreateProductGroup' with cardinality '1' maintained
