Calling Web SErvice from Forms 10g R2

Hi All
We are building a new form that calls out a web service. We used JDeveloper to build the stub and successfully import the same into Forms. We added the jar file names to class path, formsweb.cfg and default env files in the desktop. When we run the form using designer we get ORA-105100 error.
Do we need app svr to test the web services call out or can we test it from the forms builder itself. any help is appreciated. I understand that the error is due to the java class not being loaded at run time. do not know what the reason is.
I have read the how to document multiple times and have memorised the same, please do not point me to that. I have followed the instructions in that document step by step. the only difference is that the web service that I am calling is different.
Any help is greatly appreciated.

Error while calling web service from Forms 10g

Hi,
I have defined a web service and deployed at OracleAS 10g 10.1.2.0.2. Web services is working fine as per standalone invocation URL and also using a Web Service source in Portal (OmniPortlet).
I have created a web service proxy and imported the JAR file into Forms module via Java Importer. Created a button to invoke a web service and show results on message bar.
Code for WHEN-BUTTON-PRESSED:
declare
     v_javaObject ora_java.jobject;
     xo ora_java.jobject;
     v_name varchar2(30);

     v_javaObject := EmpServicePortClient.new;
     v_BigDecimalObject := BigDecimal.new(101);
     v_name := EmpServicePortClient.getName(v_javaObject,v_BigDecimalObject);
     message(v_name);

However, while invoking a service by pressing a button, getting following error at message bar:

Is there anything that I have missed in the configuration? or what else is causing it?

Without going into any technical discussion about the code, my first question is what JDK version was used to create this which was imported into the form? Understand that Forms 10 runs on JDK 1.4.2, so if you used any newer JDK version, likely there will be problems.

Calling web service from forms..

Forms Gurus,
I am using this demo to call the webservice in Forms.
http://www.oracle.com/technology/obe/obe_as_10g/deploy/callws_fromforms/forms_webservice.htm#r1
I am using a simple button to call get the conversion rate from the web service.
But my code is not doing anything. I used some insert statements to see where my code is failing and is as follows:
DECLARE
jo ora_java.jobject;
rv ora_java.jobject;
EX ora_java.jobject;
v_num NUMBER;
BEGIN
INSERT INTO XXIPAY_WEB_TMP VALUES (111,'before',20);
commit;
jo:= CurrencyExchangeServiceStub.new;
INSERT INTO XXIPAY_WEB_TMP VALUES (111,'between',20);
commit;
rv:= CurrencyExchangeServiceStub.getRate(jo,'USA','great britain');
INSERT INTO XXIPAY_WEB_TMP VALUES (111,'after',20);
commit;
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
fnd_message.set_string('Unable to call out to Java, '||ORA_JAVA.LAST_ERROR);

 commit;
WHEN ORA_JAVA.EXCEPTION_THROWN then
 EX:=ORA_JAVA.LAST_EXCEPTION;
 message(Exception_.toString(EX));
 INSERT INTO XXIPAY_WEB_TMP VALUES (111,'exception',20);
 commit;
END;
After pushing the button I am getting the following values from the table:
111 before 20
111 java_error 20
I am importing currencyexchangestub.class, java.lang.Float.class and java.lang.Exception.class.
My code is failing before executing the new function.
Where am I doing wrong? Any help is highly appreciated.
Thanks in advance.

Hey Francois,
Everything went fine according to demo until I clicked on the button to get the conversion rate. The button is inserting the "java_error" row in the table and giving out this error:
SoapException: faultCode=SOAP-ENV:Protocol;msg=Unsupported response content type "text/html;, must be: "text/xml". Response was: <! DOCTYPE HTM
I am attaching the PL/SQL package generated out of the java class. Hope this is correct:

RETURN JNI.CALL_OBJECT_METHOD(obj, mid, args);
END;
Please let me know where I am doing wrong.
One more thing I would like to mention is that my form builder is on UNIX server and JDeveloper is on my local machine. So I am ftp'ing the java class and the deployed JAR file into my home directory on UNIX server in "binary" mode. And in the CLASSPATH I am mentioning my home directory,So that the java class gets picked up when I import the Java class.
Thanks in advance,

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.

Yes, SAPHTTPA (runs on application server) and/or SAPHTTP (runs on front-end pc), one of which, is required for HTTP communication. So far, nothing too elaborate as far as SOAP goes, but the logic is simplistic. Here's some sample code:
DEST = 'SAPHTTPA'.
TRANSLATE HOST TO LOWER CASE.
MYURL = 'wssrvTest/Service.asmx/GetByOrderItem'.
CONCATENATE HOST MYURL INTO MYURL.
REQUEST_HEADERS-DATA =
 'Content-type: application/x-www-form-urlencoded'.
APPEND REQUEST_HEADERS.
CLEAR REQUEST_HEADERS.

Web services for forms 10g

Hi, Can anybody explain how to use web services in forms 10g. I have a wsdl url with me which I need to call. I also heard that I can use utl_http and utl_url package. Anbody knows what it is. So basically there are two ways to call web services into the form, either use Jdeveloper to create a stub and import it into the forms or I can use the utl_http and utl_url package. Is that right?
Please advise in details. All this is confusing.
Thanks.

Is there a way to call web service from 2 servers??

Hi,
I need to know if its possible to call web service from 2 different servers without having load balancer??? I mean, if one of the server has heavy work on, then it should call web service from the other server.
Thanks in advance.
Best Regards.

Hi,
WebLogic Cluster has this feature ( Load Balancing & Failover ). If you will deploy your WebService to a WebLogic Cluster and then If you will put a Proxy in front of it like (Apache)...Then it is Possible.
<h3>What All You Need To Do ? ...... as following</h3>
Step1). Create a WebLogic Cluster (minimum two ManagedServers)
http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
Step2). Install a Proxy like Apache in frot of them like following:
http://weblogic-wonders.com/weblogic/2010/05/13/apache-proxy-as-static-content-repository/
Or
http://weblogic-wonders.com/weblogic/2010/08/01/weblogic-httpclusterservlet-proxyserver/
Step3). Now Configure a FrontEnd Host for your Cluster by providing the ProxyServer Host name as the FrontEnd of your Cluster. This step is required to Generate the Dynamic WSDL with the Address of the Frontend.(Not of a perticular WebLogic Server)
http://weblogic-wonders.com/weblogic/2010/06/21/configuring-frontend-host-and-port/
Step4). Deploy your WebService on the Cluster
Step5). Now Hit the WebService using the Proxy URL:
Example:
http://ProxyHostname:proxyPort/ServiceContextRoot/ServiceURI?WSDL
Thanks

Calling Web Service from CRM using proxy

Hi all,
I'm facing a problem trying to call a web service from CRM (WAS 620) via XI 3.0. The response that XI recieves from the web service contains SOAP Envelope, and the mapping fails because of it. I built the proxy manually, because if I load WSDL the proxy generation in CRM generates error that sais that external definition coudn't be used.
Is there any way to remove SOAP envelope from the response while mapping?
Is it possible to call web service from WAS 620?
Thanks!!!!
Anya.

Hi Manish,
SOAP adapter does pass the message to XI (this message contains SOAP envelope although XI expects to get message without it), and during the mapping step i get "Runtime Exception in Message-Mapping transformatio~".
I suppose it's because i created proxy manually. I did so because when i imported WSDL, and tried to generate proxy in CRM, i got an error message that said that proxy couldn't be generated because external definitions are only allowed in XI 3. But my XI version is 3.0! And when I generate the same proxy in my R/3 system that is installed on WAS 640, it works.
What can I do?
Cheers,
Anya.

Calling web Service from the Custom Adapter.Is it Possible?

Hi Experts,
I am having requirment in which i have to cal com.sap.aii.mapping.lookup.LookupService for calling web Service from the Custom Adapter.Is it Possible?
Regards,
Rajesh.D

Hi Rajesh..
Just looking the problem in another angle.. if there is no constraint that you have to use XI specific API to call the web service, why dont you use usual Java API used for calling a web service inside you custom adapter (I have Microsoft background.. donno exactly how it is done in Java,, but in .NET kind of a language it is possible). SInce your adapter is in Java itself and is capable of calling web service.. collect or lookup the data whatever you want and validate...
Just a thought..
