Calling web service from oracle forms 10g

Problem Description:
I'm following the steps as per the doc:
http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://gend:83/DesignService.svc?wsdl
The service was developed by us.
Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
The code from oracle form to call web service is as below:
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(2000);
ex ora_java.jobject;
str varchar2(100);
BEGIN
jo := GendServiceClient.new;
rv := GendServiceClient.sendHello('Nora');
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;
Any help/ideas on this is greatly appreciated. Thanks.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.

Exception when calling web service from Oracle forms 10g

Hi All,
I am trying to integrate Oracle Forms 10g(V 10.1.2.0.2.) with Web Services.
There is a java class named 'authenticate' which is generated using Oracle JDeveloper.
This class is included in the forms application by using "Import Java Class" feature.
Forms built the following funtion based on that class:
-- Method: authenticate (Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
FUNCTION authenticate(
obj ORA_JAVA.JOBJECT,
a0 VARCHAR2,
a1 VARCHAR2) RETURN VARCHAR2 IS
BEGIN
args := JNI.CREATE_ARG_LIST(2);
JNI.ADD_STRING_ARG(args, a0);
JNI.ADD_STRING_ARG(args, a1);
message('here1');
RETURN JNI.CALL_STRING_METHOD(FALSE, obj, 'mypackage/AuthenticatorWebServiceServiceStub',
'authenticate', '(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;', args);
message('here2');
END;
However when the above code is invoked it shows the message 'here1' on the form and then throws the following exception: java.lang.Exception: java.lang.ClassCastException
Please suggest me what's wrong with the code. I appreciate your time and help.
Thanks,
Scott.

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.

Calling web service from oracle forms fails with ORA_JAVA.JAVA_ERROR

Yes, it is the message line - so basically this call fails => rv:= CurrencyConvertorStub.ConversionRate(jo,'CAD','USD'); and control goes in the exception block
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);

How to access web service from Oracle ?

Database version: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0

/*Construct the information you want to send to the webservice.
Normally this would be in a xml structure. But for a REST-
webservice this is not mandatory. The webservice i needed to
call excepts plain test.*/
t_Request_Body := 'the data you want to send to the webservice';
/*Telling Oracle where the webservice can be found, what kind of request is made
and the version of the HTTP*/
t_Http_Req := Utl_Http.Begin_Request('**webservice address**',

ORA-12545: Connect failed because target host or object does not exist
But I can link to the web server by going to **webservice address** through my browser.
Is there any ACL should be open in order to have this capability? I asked my DBA but she asked me I will need to give her username/password/ip in order to open an ACL...
however there is no username/password required while visiting the web service...
Any help would be highly appreciated..

So it could be a firewall on my database side that needs to be open in order to visit the hostserver?The "web browser" code (your PL/SQL code using UTL_HTTP) runs on the Oracle database server. It needs the same type of network access that your browser on your PC enjoys. (firewalls opened, proxy authentication if required, etc).
On 11g. Not on 10g.I saw the example code you post through the link you provided... will those only work on 11g?
If it can work on 10g, what package or what steps I need to follow in order to have that working on me?The code I've posted will work on both versions. My comment was regards to ACLs. No ACLs existed on 10g. So you only need execute privs on the relevant packages (e.g. UTL_HTTP, etc).
ACLs were introduced with 11g - so on 11g you also need the DBA to create an ACL for you that will allow UTL_HTTP access to the network.

Well, you should first test if your webservice is reachable with a simple WS - Client or a Browser - Plugin, then verify the respones of the web service and after that you can take further investigations on your problem domain. The error - message refers to a line in your function, obviously, but I can't see which line and because there is more than one call to sys.utl_dbws I don't see at what point the script fails. NULL - Pointer - Execptions usually indicate that a method was invoked on a variable which should contain an object reference but is NULL.

How to call web services from Acrobat API using VC++

Hi,
I have api plugin which installs custom menu and tool bar to adobe acrobat. In this plugin once user installs this plugin, he need to activate this tool by entering key value. this limites to limited number of users (which is decided by client while buying).
I am using javascript and VC++ with Visual studio 2008.
So can some one suggest me how can i achive this.
Thanks
Shiva

First, this is the scripting forum. You want the SDK forum.
Second, this isn't an Acrobat issue. It's a C++ programming issue. If you want to connect to a web service you'll need to use the windows or mac socket interface. If you're doing this using MFC then there is a library for internet interactions. If not, I'm sure there is still a library for it, I know there is a system API, you'll just have to look around. But the main point is that it's completely outside the Acrobat SDK.

Hello,

Please help me how to call web services from ABAP and how to pass value. Any one help me with example.
Thanks
RaviKumar

Hi Ravi,
If you can call EJB from ABAP and from EJB call Web service which you want to call. I am giving code to write in EJB business method processFunction.
public void processFunction(Function function) {
   IRepository repository;
   repository = new Repository("TestRepository");
   JCO.MetaData fmeta = new JCO.MetaData("ZTEST_EJB");
   fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.IMPORT_PARAMETER, null);
   fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.EXPORT_PARAMETER, null);
   fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.EXPORT_PARAMETER, null);
   repository.addFunctionInterfaceToCache(fmeta);
   JCO.ParameterList input =
   function.getImportParameterList();
   JCO.ParameterList output =
   function.getExportParameterList();
   JCO.ParameterList tables =
   function.getTableParameterList();
if (function.getName().equals("ZTEST_EJB")) {
                    output.setValue(input.getCharArray("REQUTEXT"),"ECHOTEXT");
output.setValue("This is a response " + table.getString("E_NAME") +" " + output.getName(1), "RESPTEXT");
else if (function.getName().equals("STFC_STRUCTURE")) {
JCO.Structure sin = input.getStructure("IMPORTSTRUCT");
JCO.Structure sout = (JCO.Structure)sin.clone();
try {
      System.out.println(sin);
   catch (Exception ex) {
       System.out.println(ex);
                    output.setValue(sout,"ECHOSTRUCT");
output.setValue("This is a response from Example5.java","RESPTEXT");
}//if
Here REQUTEXT, ECHOTEXT are import parameter and RESPTEXT is the Export parameter of Function module ZTEST_EJB in SAP.
Here from this bisuness method you can call web service which you want and give back the result of webservice to ABAP F.M.
