How to call web service using J2SE 1.3?

Dear All,
i have developed a web service by jdev 10.1.3 (JAX-RPC with web service security
enabled).
i generate the ws proxy (jdev 10.1.3) and run it with wsclient_extended.jar (required JDK 1.4.1 or above??).
but one of my client say he has to use J2SE 1.3.x (as OS=AIX 4.3 that without J2SE
1.4.x ), could anyone tell me how can generate ws proxy (with supporting
library) for jdk 1.3.x?
if oracle don't have such library / tools, any third party tools / library available?
thank you.

[Best practice] How to call a service from custom Java code

Hi all,
I'm wondering what the best method is to call a standard service from custom Java code?
In a specific situation iDoc script is extended with custom functions with a custom component. There's Java code mapping to these functions that is executing these functions. The iDoc script functions are called from a workflow entry script.
In the Java code that runs when the custom iDoc functions are called, I want to call a standard Content Server service. I don't think that the m_service variable is available, so filling the binder and using m_service.executeService() probably isn't possible.
Also, if it were possible (that is, if I want to call a standard service from my own custom service Java code), what would then be the best method to do so?
Regards, Stijn

Hi Sapan,
Let me explain a bit further.
I'm an UCM consultant trying to solve a problem that occured at a client when they installed the CS10gR35CoreUpdateBundle.
Content items are entered into a Workflow when they are checked in. Part of one of the entry scripts of the a workflow step is that related content to the content item in the workflow is (re)submitted for conversion.
To achive this, a custom component provides an iDoc script extension. This iDoc function (resubmitForConversion) is implemented in Java (the class extends ScriptExtensionsAdaptor).
In this Java method, first the related content items are fetched. Then the service RESUBMIT_FOR_CONVERSION should be called for all dID's in of the related content.
Thus, at a certain point in the custom Java code, a native Content Server service must be called. Of course the class of this Java code does not extend the Service class, so the m_service object isn't available.
The thing is: before installed the 10gR35CoreUpdateBundle everything worked OK. This code was used to execute the service:
        Workspace workspace = CommonUtils.getSystemWorkspace();
        String cmd = binder.getLocal("IdcService");
        if (cmd == null) throw new DataException("!csIdcServiceMissing");
        ServiceData serviceData = ServiceManager.getFullService(cmd);
        if (serviceData == null) throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined", null, cmd));
        Service service = ServiceManager.createService(serviceData.m_classID, workspace, null, binder, serviceData);
        UserData fullUserData = CommonUtils.getFullUserData(userName, service);
        service.setUserData(fullUserData);
        binder.m_environment.put("REMOTE_USER", userName);
        ServiceException error = null;
        try {
            service.setSendFlags(true, true);
            service.initDelegatedObjects();
            service.globalSecurityCheck();
            service.preActions();
            service.doActions();
            service.postActions();
            service.updateSubjectInformation(true);
            service.updateTopicInformation(binder);
        } catch (ServiceException e) {
            error = e;
        } finally {
            service.cleanUp(true);
            if (!CommonUtils.isWorkspaceConnectionInTransaction(workspace)) {
                 workspace.releaseConnection();
        }the first problem was that the CS began to complain that a transaction was started within another transaction. So I suspect that the 10gR35 update wrapped a transaction around a workflow script entry.
With some decompiling I figured out how a service is called from iDoc with the <$executeService()$> command. So I replaced the code above with:
              String cmd = binder.getLocal("IdcService");
            ServiceData serviceData = ServiceManager.getFullService(cmd);
            if (serviceData == null) throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined", null, cmd));
            Workspace workspace = CommonUtils.getSystemWorkspace();
            Service service = ServiceManager.createService(serviceData.m_classID, workspace, null, binder, serviceData);
            UserData fullUserData = CommonUtils.getFullUserData(userName, service);
            service.setUserData(fullUserData);
            binder.m_environment.put("REMOTE_USER", userName);
            service.initDelegatedObjects();
            service.executeSafeServiceInNewContext(cmd, true);This solved the transaction problem but introduces another problem: !csUnableToResubmitItem,(null)!csIllegalScriptAccess,RESUBMIT_FOR_CONVERSION
The Service Reference Guide says that the access level for RESUBMIT_FOR_CONVERION is 33 (Read, Scriptable). However, in shared/config/resources/std_services.htm the access level is specified as 2 (write).
Thus, my question still is:
What is the best method to call a standard Content Server service from any Java code (so without extending the Service class, or having the m_service object available)?

How to call Web Service using http?

Hello everyone,
I have created a web service in weblogic 8.1sp4. The web service is deployed and in the test page in the administration console I see that the wsdl is sth like
http://localhost:6101/SomeWebService/SomeWebService/SomeWebService?WSDL
How is it possible to call the web service operation (let's say someOperation) using http? The problem is that the client which will call the operation is not a java or .net one and is needs to do the call using a URL. I have tried sth like
http://localhost:6101/SomeWebService/SomeWebService/SomeWebService?string=somestring&operation.invoke=someOperation which is the URL used in the test page in the administration console and although it works, instead of getting the SOAP response back I get the whole html page returned by the test page.
Please help me,
Thanks,
Yiannis

Hi Shreyas,
From your post, it seems that you are using SharePoint 2013 workflow platform in SPD.
If that is the case, we can use Call HTTP web service action to get the item data, but we cannot use Call HTTP web service to create a new item in the list in another web application with these data.
As my test, we would get Unauthorized error when using Call HTTP web service action to create a new item in a list in another web application.
So I recommend to achieve this goal programmatically.

How to call Web Services with Sun Java Studio Creator?

Can someone from Sun please explain how to use the sample Web Services USWeather and GoogleSearch in Sun Java Studio Creator (no Portlet Application)?
I read the Web Service Tutorial Accessing Web Services (http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/webservices.html) and this blog entry: http://blogs.sun.com/roller/page/winston?entry=code_google_search_in_no .
But the proposed solutions do not work with the services USWeather and GoogleSearch.
Thank you.

Thank you for your answer, dongmei.
It seems that the MethodResultTableDataProvider does not return the response of the web service as a value field if the WSDL contains only one result element.
E.g. from WSDL of the USWeather Web Service which returns theGetWeatherReportResult string:
<?xml version="1.0" encoding="utf-8"?>

            <s:element minOccurs="0" maxOccurs="1" name="GetWeatherReportResult" type="s:string" />
          </s:sequence>
        </s:complexType>
      </s:element>
      <s:element name="string" nillable="true" type="s:string" />
    </s:schema>If I drag the web service method on the page and I should be able to select the response value in the Bind to Data dialog box. But there is no value field. Value fields only occur if the web service returns more than one value.
The question is how can I get the response GetWeatherReportResult from the service.

How to call WEB Service From SAP 4.6 c

Hi Friend,
How to call WEB Service From SAP 4.6 c Report
Thanks in advance.

It is not possible to directly call a web service from SAP 4.6c.
Indeed, web service enablement is available as from Web AS 6.20, thus as from SAP R/3 4.7
So as described above, the solution is indeed to make use of PI(XI) for this.

Call web service using code.

we want to call a web service from ADF JSP form.
We used web service data control. But deployment failed.
we applied Patch 5878326 to JDeveloper 10.1.3.3.0 and OAS.
But problem is not solved.
So we need a new way to call web services.
is there any other way to call web services from Jdev.
any code sample will be appreciated.
Thanks.

Workaround for the Connection Failure
In JDeveloper, locate the .deploy file in the Resources folder of your web application project.
Double-click the file to open the WAR Deployment Profile Properties dialog.
Expand File Groups - WEB-INF/classes - Contributors.
In the Contributors panel, click Add and use the Browse dialog to locate the .adf folder in the root for your application (for example, /jdev/mywork//.adf path.)
Select the .adf folder and add it as a contributor to the deployment profile.
Note that the .adf folder does not become part of the deployable archive. This merely ensures that the contents of the META-INF get placed in an appropriate location in the archive that will permit the web container to find it when the application loads.
The failure to get the connection to Webservice is beacuse the "connections.xml" is not available in the deployed archive.
This has been release note'd as in
http://www.oracle.com/technology/products/jdev/htdocs/10.1.3.0.3/10.1.3_addendum.html under "Deployment issues"

How to develop web service using Intellij Idea 6.0

How to develop web services using Intellij Idea 6.x. A sample web service and service client is needed with full procedure. Thanx in advance.

Web service is technology not a tools that bundle with IDE.
For example you can't say how can I develope object orented program with Eclipse.
1- You should get some general info about SOAP, WSDL and Web sevice usage
2- Start to implmenet a simple Hello world web service and deploy it on application(web service) server
3- Write Client code and test it.
for step 2,3 Apache Axis(2) could be a good solution for developement or you can use JAX-WS for sun

Invoking a web service from a java code

Hello
I created a simple Web service using JDevlper. It contains two methods
1) getInf int () {
return inf;}
2) void setInf (int a) {
inf = a;}
I have deployed it on Oracle Application server. By inserting the address in a browser, I tried both methods and it works correctly.
Here I am looking how to invoke this web service using a java client and use the method setInf (5 ) / * for example * /.
I search but I have not found an answer that works :(. I hope you could help me to solve this problem.
Thank you in advance

Because you weren't told what to get, perhaps you already have it eh?
What you want to read up about is JAX-WS, which is the webservice API bundled by default with your JDK (Java 6 and up). You'll find the wsimport tool in the bin directory of your JDK. I recommend you explore that directory and read up about all the executables you can find there, to be more prepared in the future. Know the tools you work with and all that. Most tools have a manual on this website:
http://www.oracle.com/technetwork/java/javase/tech/index.html
(under tools and utilities). Not wsimport, that is part of the jax-ws documentation. Better you look for jax-ws tutorials using Google, it will be quicker.

          /*can produce errors which must be caught*/
          catch(Exception e) {
               e.printStackTrace();
               System.out.println (e.toString());
