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.

Web services for foms 10g on the forms server.

Hi,
I have created the sample form in 10g (windows based) where it calls the web service to get the currency exchange rate (http://www.oracle.com/technology/obe/obe_as_10g/deploy/callws_fromforms/forms_webservice.htm).
I have now ftp'd the form into my forms server in unix and compiled it using compile.sh. Now my question is, where to add the jar files in the unix forms server. Since my archive.jar and other jar files are in my windows explorer directory, do I need to ftp all that into the forms server? If yes, what exactly do I need to put in the server.
Once I put all the files in the forms server, where do I need to set the paths.
Please advise. Urgent.
Thanks.

I don't know why you need to place them into the CLASSPATH of the target machine? For deployment of my forms from a linux iAS EE installation, all I do is to place the related (and custom) jar files to the iAS BI (business intelligence components)/forms/java directory and then list the jar files properly in the iAS BI/forms/server/formsweb.cfg file's application related section. The jar files then downloaded to the client when they access to the form (via Sun JRE plugin on linux clients or Jinitiator on windows clients). I know I had to place those jar files in CLASSPATH for iDS (forms development) but not for the deployment.
I hope this proves useful

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);
     javaException ORA_JAVA.JOBJECT;
     v_BigDecimalObject ORA_JAVA.JOBJECT;
begin
     v_javaObject := EmpServicePortClient.new;
     v_BigDecimalObject := BigDecimal.new(101);
     v_name := EmpServicePortClient.getName(v_javaObject,v_BigDecimalObject);
     message(v_name);
exception
     WHEN ORA_JAVA.JAVA_ERROR THEN
-- In this case, the error would be

-- Print out the Exception by using the toString()
-- Method of the exception Object
message(Exception_.toString(javaException),acknowledge);
-- and clean up
ORA_JAVA.CLEAR_EXCEPTION;
END;
Forms got compiled successfully.
However, while invoking a service by pressing a button, getting following error at message bar:
java.rmi.RemoteException:; nested exception is: HTTP transport error: javaxml.soap.SOAPException: java.security.PrivilegedAction
Is there anything that I have missed in the configuration? or what else is causing it?

(urgent) web cache for forms 10g

Hi all,
We have application running on oracle 10g Aps resently migrated and we got couple of freequently used forms by default my webcache is on but i dont know how can i specifialy say that thease forms to be cached like if i see my webcache page i could see some of the gifs had cached but no specific forms how can i do this.
I shall be highly be obliged if one can clear my queries in the forum may wish to add to 2cents to my infinetly minimal knowledge of webcache.

Not really true. You could setup a rule to cache the JAR files for Forms. Additionally, you could cache the GIF files accessed by the applet, though it would be better to move those image files into a JAR file. Why?...
If you use a static HTML file to call your forms, that would be cached by default.
Because the client JVM caches the files. You can view this in the Java Console of JInitiator or your Java Plug-in. Additionally, you can see when the image files are served from the JAR files by looking in the Java Console as well. Change to level 5 trace in the Java Console window and look for GIF files with a path that includes http://server/forms/jave/filename.jar!/filename.gif. Notice the ! symbol. That shows a client JAR cache hit for that GIF file. Served locally, doesn't even make it to Web Cache!
The rest of the communication really isn't cacheable. Communication goes from the Applet (Client JVM) through Web Cache to the HTTP Server to the OC4J_BI_Forms container (OC4J JVM) that runs the Forms listener servlet which talks directly with the Forms Server runtime process running as a Unix process (C, not Java).
So, the only communication that goes between the applet and the Appliction Server is just the messages between the applet and Forms Server process telling the applet how to refresh the display on the client's applet screen and telling the Forms Server process what to do with the data and code being run. This communication is optimized by using message diffs, so it is relatively efficient. But an application not optimized for the web might use chatty functionality that slows things down a bit.
Anyway, xhomet is essentially right in that Web Cache doesn't do much of any significance besides load balancing. Caching JAR files might make sense for you though if you have a lot of users all getting this JAR or an updated JAR at the same time.
Hopefully you foundthis interesting.

    }Also the secured web service was generated from Webcenter Content 11.1.1.6 that is why it's a secured web service.

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 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.

Create a Web Service for Exchange with form based authentication ?

I want to create a Web Service in Apex that can create appointments in my exchange calendar. Exchange is offering web services for that.
When i try to create the web service reference in Apex i provide the URL and my Exchange login, but it is failing.
The exchange guys told me, that there is a ISA Server running where i need to authenticate through a form.
Does anyone know, how i can implement a webservice in Apex, when the access to the wsdl url needs login through a form ?
Or : what other types of authentication does Apex know ? What possibilities do i have ?
Thanks for answers.
Bernd

Hi
Presume you've already found this information, but in case not ....
Exchange 2007 provides out of the box web services, see

As a disclaimer - neither myself of the team I work with have tried to use these web services within APEX.

Configuring Web Services for Oracle XML DB

Hi all...
I think I need some help one this subject....
We have a 10G Release 2 Oracle single instance ( not RAC) install on a Linux Redhat v5.3 64 bit server. Are developers are user Visual Studio .Net and wnat to send xml files to a web service so that the xml file (containing data) can call a PL/SQL package (to be written) which will take the data out of the xml input file and insert rows into a prefined table within the instance. Now they have browsed the web and have come upon the following links...
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb22pro.htm#i1026724
Currently, within the database I looked at the schema XDB and have unlocked the account and connected as the user XDB. There are some 680 objects in the following groups...
SQL> select object_type, count(*) from dba_objects where owner='XDB' group by object_type;
OBJECT_TYPE COUNT(*)
SEQUENCE 2
PROCEDURE 5
OPERATOR 8
LOB 334
LIBRARY 12
PACKAGE 20
PACKAGE BODY 17
XML SCHEMA 25
TYPE BODY 5
TRIGGER 12
TABLE 36
INDEX 51
FUNCTION 5
INDEXTYPE 2
VIEW 2
TYPE 144
16 rows selected.
Now in the links above it mentions that the xdbconfig.xml needs to be altered etc. However, I have searched the entire $ORACLE_HOME and there is no file definition of that description.
From a DBA prospective...what do I have to install on the Linux server? I assume from the Oracle Database 10g Companion Products I need to lay down Oracle HTTP Server in a new Oracle home as the first step...or not? Does the HTML DB need to be installed as well?
And for Configuring Web Services for Oracle XML DB...what else has to be installed? And from what product line?
Thanks in Advance....
Cheers
Roegr

Hi Marco...
First of all ...thanks for the reply.
I followed the link and the infor in that web page. However, there were a few things that did not work....
1. The http://localhost:8080/ as is brought up a web page withe the heading as
==========
ORACLE DATABASE 10g EXPRESS EDITION LICENSE AGREEMENT..
==========
The other browser test ftp://localhost:2100/
did not find any page?
2. Then I went onto running (as the sysdba) the pl/sql to enable the ORAWSV Entry Service
however it error out. So I did a describe on DBMS_XDB and the function deleteServlet does not appear
then I had a look and this link to > http://www.liberidu.com/blog/?p=471
was for 11G and the other link > http://docs.oracle.com/cd/B28359_01/appdev.111/b28369.pdf
was for 11G.
However, we are on 10G
=================
SQL> select * from V$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for Linux: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
==================
So is there must be other sql for 10G?

JDev: Generating Web Services for Streaming Attachments

Hi,
I am a newbie in this field. I am trying to generate web service code using JDev (10.1.3.3). I have an interface class and the implementation class. When I am trying to generate J2EE Web Service for the implementation class, I am getting the following error:
"The selected class doesn't contain any public method publishable in a web service".
Following is my code:
Interface:
package testing;
import oracle.webservices.attachments.Attachments;
public interface ImageStore extends java.rmi.Remote {
public void storeImage (String name, String desc, Attachments attachments) throws java.rmi.RemoteException;
Impl:
package testing;
import java.io.InputStream;
import javax.activation.DataHandler;
import oracle.webservices.attachments.Attachment;
import oracle.webservices.attachments.Attachments;
import oracle.webservices.attachments.IncomingAttachments;
public class ImageStoreImpl {
public static String storeImage(String name, String desc, Attachments attachments) throws Exception {
IncomingAttachments incomingAtts = attachments.getIncomingAttachments();
if (incomingAtts == null || !incomingAtts.hasNextAttachment())
throw new Exception("Expected request attachments");
Attachment imageAtt = incomingAtts.nextAttachment();
String id = imageAtt.getId();
DataHandler dataHandler = imageAtt.getDataHandler();
InputStream imageStream = dataHandler.getInputStream();
//-- Store image metadata and stream image bytes
if (incomingAtts.hasNextAttachment())
throw new Exception("Expected only one attachment");
return "success";
Can someone please let me know how can I generate the web service for this code using JDev.
Thanks,
J

Hi J,
Why is the concrete class not implementing the ImageStore interface? Anyways, I believe the ImageStoreImpl#storeImage method cannot be static if you want to generate a WS.
Furthermore, you should consider posting your question in the JDev 10G (JDeveloper and ADF forum as this one is for 11G.

How to create web service for a Java class in SAP NetWeaver Studio

hi all,
i am using SAP Netweaver Developer Studio.have created a normal java project and i want to create web service for one of the classes in this project. i used the Web Service Creation Wizard to create a web service for this class. but it says there's no methods available for VI. all my methods in this class are public, what should i do?

Hi,
I guess there are other ways. But this is an easy way, if you find the right wizards.
Besides this it is good practise to define interface methods so that session bean implement these interface methods, and thus seperate the interface from the implementation.
In this approach you will need 3 projects:
An enterprise application project (will contain EJB Module)
An EJB Module project (will contain session bean)
A Java project (contains code that implements the session bean methods)
In my previous post I suggested to use a J2EE web mudule project. This was a mistake, it should be EJB module.
But it should be possible to do it in another way. It is up to you.
Good luck, Roelof

Get xml data from a web service into Forms?

Hello folks! I am reading active directory info from a web service into forms via imported java classes. I can read from functions that return strings just fine, but I have to get the output from getGroupUsers which returns an XmlDataDocument. How do I read this in and parse it in Forms?
I will be grateful if y'all could point me to an example.
Thank you,
Gary
P.S. Here is a snippet of how I get the full name by passing an ID:
DECLARE
jo ora_java.jobject;
rv varchar2(100);
BEGIN
jo := ADSoapClient.new;
rv := ADSoapClient.getUserName(jo, 'user_ID');
:block3.fullname := rv;

Hello,
Since you are already dealing with server-side JAVA, I would suggest you create a method that would do the parsing server-side and what your PL/SQL will be dealing with is just the return string.
Here is a method I use to read an XML file (actually, it is an Oracle Reports file converted to XML) and from the string version, I will do search, replace and other things.
So, from getGroupUsers which returns an XmlDataDocument, you can adapt this method to get your data server-side and let the form module read the output data.
<blockquote>
private String processFileXml(String fileName, int iFile) throws ParserConfigurationException, SAXException,
IOException, XPathExpressionException{
try{
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setNamespaceAware(true);
InputStream inputStream = new FileInputStream(new File(fileName));
DocumentBuilder builder = domFactory.newDocumentBuilder();
Document doc = builder.parse(inputStream);
StringWriter stw = new StringWriter();
Transformer serializer = TransformerFactory.newInstance().newTransformer();
serializer.transform(new DOMSource(doc), new StreamResult(stw));
return stw.toString();
catch (Exception e){
System.err.println(e);
System.exit(0);
return "OK";
</blockquote>
Let me know if this is of nay help.
Thanks.

Calling Web Service from Froms 10g

I was following the tutorial located here: http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
but the link is no longer working. I have tried searching at the new Oracle Learning Library but they do not even offer an option for Forms 10g. Could someone point me in the right direction to find this tutorial?

Francois,
If you can see the text but cannot see the images it likely means you have not enabled them. Click on the link in that page that appears as follows:
<font color="red">Viewing Screenshots
Place the cursor over this icon to load and view all the screenshots for this tutorial. (Caution: This action loads all screenshots simultaneously, so, depending on your Internet connection, may result in a slow response time.) </font>
If you still cannot see the images, ensure that java scripting is enabled in the browser security.
I will pass your comments to Grant for his review since he is leading the investigation of this problem.

Thanks Venu for your input.
Unfortunetly we do not have Java stack on our development system. You said we can test it by SOAP UI tool. Where do I see the WSDL file for the service?
I used WSDL from SE80 --> Service --> WSDL tab, but SOAP UI does not accept this format ?
What are the other ways I can test this web service? I think about SAP PI, importing RFC & creating web service or creating ABAP proxies... Which is the best way to go forward in case you do not have Java stck.
