Doc for 10g Web Services for EJBs

I'm trying to determine if any documentation exists for 10gAS that discusses how to publish a statless session bean as a web service. The only thing I'm found so far is a tutorial called "Expose a Stateless Session EJB as a Web Service Endpoint through JAX-RPC interface", but I've found it lacking in detail and possibly incorrect. For example, it mentions a wsadmin tool that I don't see in the 10gAS release and it discusses how files like mapping.xml and webservices.xml can be created by JDeveloper. However, the 10g JDeveloper I downloaded doesn't see to support this.

Unfortunately the doc is the how-tos right now. However, there are a couple of pointers - this article by Anirban Chatterjee - http://otn.oracle.com/tech/webservices/htdocs/j2ee14/jsr109.html - describes the configuration behind it.
The JDeveloper interface is on the cusp of being released - it is just going through QA. I have written a tutorial on what it looks like here:
http://otn.oracle.com/tech/webservices/htdocs/series/jaxrpc1/index.html
But this tutorial is not linked publicly yet because it isn't released ... when the extension becomes available this link will be hooked up publicly. Please treat it as a preview right now.
Could you describe the errors that you are encountering. There are a number of bugs that we have been collecting with the preview and we hope to do a refresh soon. It would be good to know if yours is a known one or not.

XI for create web servicies for SAP R/3 4.6C

Hi All,
we are implementing PM (Plant Management) module of SAP R/3 4.6C and we have the necessity to create web services for some PM functionalities. Infact we need to integrate our SAP R/3 4.6C with other applications (non-SAP) through TIBCO (it's mandatory). So we think to use SAP XI. Moreover our users don't want to use SAP GUI for the accessing to the PM functionalities but they want an UI more friendly. So we think to use SAP EP.
Which is your opinion about this architectural scenario? Is it possible to fulfil the requirement of our business users with a more simple architectural solution (for example with WEB DYNPRO)?
Many thanks in advance for your collaboration.
Regards,
Bob

Infact we need to integrate our SAP R/3 4.6C with other applications (non-SAP) through TIBCO (it's mandatory). So we think to use SAP XI.
TIBCO is another middleware. So once you expose your R/3 functionalities as web service, you may directly use TIBCO to integrate and XI won't be required at all.
Moreover our users don't want to use SAP GUI for the accessing to the PM functionalities but they want an UI more friendly.
WebDynpro application would provide you an easy GUI and could act as Soap client as well to send data.

Sample code for calling web services for export

Hi I am trying to use web service ExportProject to export a project out of Primavera DB. The Export service uses MTOM (Message Transmission Optimization Mechanism) to send the output files as attachments. Need some information on
- Can the export service be specified a location for the transfer? or it will come attached in the response?
- How do i access this attachment? I am using PL/SQL for doing this.
Any help will be appreciated.

I am not a pl/sql guy but there is a java example in the demo code that might help you figure out a pl/sql approach.
Look in WSDemo.java in the exportProject method. The WSDemo.java file was located in the following directory on my system: \Oracle\P6EPPM\ws\demo\Java\JAX-WS\src\com\primavera\wsclient\demo

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

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?
Cheers

How to create web service for database application

Hi everyone
Is it possible to create a web service for an apex database application page which has reports and radio fields and dialog boxes and validations in it. IF it is possible to create, pls help me with example or step by step procedure. I have seen all oracle docs of implementation of Web services in apex but unable to figure out how to get that link of wsdl for an application.
Thanks in advance.

Sandeep Artham

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

Dynamic destinations for adaptive web service in webdynpro for java

Hi,
Please advice me on how to create dynamic destination for adaptive web service model in webdynpro for java.
Regards,
Patana

Hi,
If this is the case, then use the HTTP destination for this.
What you need to do is:
1. Create one HTTP destination in visual administrator at services-> Destinations. Provide HTTP url of the your web service and the security options.
2. Specify this HTTP destination in the code before executing web service model.
Write following code for that:
wdContext.current<node name>Element().modelobject()._setHTTPDestination(<Specify HTTP destination name>);
Then execute your web service model.
Now, whenever you want to change the server on which your web service is running, make change in the HTTP Destination in visual administrator.

(268625273) Q WSI-29 Can you give any performance benchmarks for WLS web services?

Q<WSI-29> Can you give any performance benchmarks for WLS web services?
A<WSI-29>: It is very difficult to quantify performance aspects of web services
since they depend on so many variables including but not limited to: backend system
processing by stateless session beans and message driven beans, size of XML SOAP
message sent, system hardware (CPU speed, parallel processing, RAM speed) and
system software (JVM type and version of WebLogic server). However, let me point
out that the EJB backend processing of requests both have the best possible scalability
within the EJB2.0 specification (both stateless session and message driven beans
can be pooled) and servlets have a proven scalable track record. Thus it should
be possible to scale your web service deployment to meet demand. The overhead
in processing XML within the servlet can be significant depending on the size
of XML data (either as a parameter or a return type). While WLS6.1 does not have
any features to address this performance concern, WLS7.0 will feature Serializer
and Deserializer classes which can be dedicated to the XML to Java and Java to
XML translation (they can also be automatically be generated from a DTD, XML Schema
or regular JavaBean).
It is true that web services are not the fastest way to process client requests
but BEA is committed to making WebLogic server the fastest possible service provider.

Getting complete WSDL for the web services created in J2EE

Hi,
I have created a web service using Netweaver developer studio for a J2EE project (complete EJB, WEB and Appln Project) similar to CAR rental application.
I also have tested the web service in web service perspective and it is working fine. Now i want to call this web service from XI. Therefore i need the WSDL for the same. The testing screen also gives the WSDL for the web service. But it has got number of links inside in the forms of import.
Editing all those documents and forming the complete wSDL is very difficult..
How do i do it??
Abhijeet

Hi,
When I opened the wsdl it has number has a wsdl:import location tag..which refers to binding.
when opened this import location we have one more import location for porttypes.
When combined all thhree e.g. service, binding and porttype we get the complete WSDL which i could comofortably import in XI and further process.
This way i coudl succesfully call a web service from XI.
I used Stylus studio for editing WSDL.
Thanx

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.

Standard Web service for Plant maintenance

Hi Gurus,
I am new to Web services.Could you plese let me know is there any standard web services for Plant maintenance?
Thanks & Regards
Bhuvana

Hi,
This is the mail which i got from Client.
We have a prospect wanting to see a proof of concept (and pay for it) of SAP -GIS integration using web services. No specific requirement. Fetch a bunch of work orders from SAP using web service and display on a map - can be the POC.
Please review the attached doc. Figure out whether any standard web service is available, if not a BAPI can be converted to web service quickly.
Attchment contains Utilizing State oriented Communications
for Web Services based on BAPI With Microsoft Visual Studio
2005.U can check it in Google with the same name.
They just asked about is there any Standard web services available for Plant maintenance.

Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.
Thanks

How To Set Parameters in a SOAP-Message for QUERY_VIEW_DATA Web Service

Hi all,
I want to use the QUERY_VIEW_DATA Web Service to get data from BI through an existing BEx-query.
How can I set a navigation status as it is stated in the SAP documentation [Web Service for Accessing Query Data|http://help.sap.com/saphelp_nw04/helpdata/en/d8/3bfc3f8fc2c542e10000000a1550b0/frameset.htm]?
I am able to set filter values but setting any parameter with the name 'CMD' has no effect to the response.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">

We use SAP NetWeaver 7.0 EHP1. The documentation mentioned above belongs to NetWeaver 2004s and I can't find it in the docu for 7.0. Does that mean the QUERY_VIEW_DATA is deprecated?
Thanks for your help!
Best regards
Heiko Braeske

Dear Heiko,
did you solve this problem?
We are facing the same problem. Every parameter that requries "cmd" does not work. I guess we don´t use this paramter the right way.
