EJB and Web Services

Hi,
I have created a EJB project with Stateless Session Bean having just one method, Java persitence (connnection to MS SQL). I have added this project to the Enterprise project as well.From the context menu when I select to create Web Service. The method is not selectable.
What is going wrong?
Can somebody please help?
Best regards,
Dharmi

Hi Dharmi,
How did you do that? Create an EJB which connects to MS SQL?
Are there specific jars or something that have to be added to the EJB?
Did you also have to install a SQL server driver and such?
Can you provide a step-by-step for the creation of an EJB which gathers data from MS SQL?
Kind regards
Allan

Error during EAR deployment with EJB and web service

I created a simple stateless EJB with one method called echo that returns a string. I created a web service using the wizard, did a build and deployed. The deployment did not report an error, but the logs in the visual administrator showed the follwoing message, and the web service did NOT deploy.
Am I missing something related to EJB and web service security?
PLEASE HELP ME.

EJBs and web services in Application server ??

Hi all,
I just wanted to ask for a help in a scenario that i am facing:
I have a Application that relies on EJBs for Business Logic
I basically use the Jboss A/s[4.2.2 GA] server for the same and now there is a need to Expose these bean methods through a web service
so that our web team can make use of the same Business logic.
Currently i have implemented a End point interface that my Bean class implements so that i can expose
my bean methods to the web team
Req:
I want to create a separate Enterprise Bean which resides in the same JVM as my Application bean , and acts as a wrapper for my application bean
Also,
Further elaboration of the problem is as follows:
THE existing Application beans Remote interface has all the business methods that i want to expose.
The new bean should act as a delegate which intercepts the web clients call extracts the request from the call
and passes it to the application bean methods.
So this basically requires that new bean should be able to communicate with my application bean +(Which is BTW a stateless session bean)+
and pass on clients requests to the same.
Kindly provide suggestion for the same or any ideas as soon as possible
thanks again

Edited by: RainaV on 14 May, 2009 6:57 PM

Let me make it more clear for everyone
Let [A] be my application bean which has all the business Logic.
is a new wrapper bean that needs to communicate to bean [A] for accessing the Business Logic
The requirement for creating Bean[B] is two folds
1) it will provide a wrapper class for breaking down the web client requests,
which are in XML format;
into simpler data structure which can be passed as parameters to bean [A}.
2)This bean [B] will send the response back to the web client who is in need of the service
Now as pointed out by one of the guys why not create a Local interface that is not possible at this point as Most of the session bean methods have been declared to throw
Remote Exceptions and i am faced with the issue that this Design mistake is irreversible due to the Size of the Code and other factors
Now i have been looking and some Alternatives for the same .
The problem is i have not been able to find any way to do the same and need suggestions and ideas if anyone has some on this issue
i hope this clears the matter
thanks again

Deployment Aborted (EJB and Web Services)

Hello All.
In SAP Netweaber Developer Studio I created a Project with an Entity EJB and another Sesion EJB.
The Sesion Bean uses the Entity Bean (persistence). After this, it generate a Web Services.
After building the project ejb and project EAP. Within the Project EAP I took file Persistent_EAP.ear and to make respective deploy on the Server, in the Deploy out View I get the message 'Deploy Aborted'.

Could someone please help me?
Thanks in advanced,

Dear Esther,
This exception usually happens when the application is not packaged properly.
It seems that the J2EE engine web services deployment processor is looking for a descriptor which is absent in the jar file.
This could happen for instance if you forget to save all the modified files before rebuilding.
Unfortunately I cannot tell you which web service descriptor is missing, without looking at the packaged application.
Try the following:
1) Regenerate your virtual interfaces
2) Save all modified files
3) Rebuild the application
4) Deploy the application again.
Best Regards,
Abhishek

Injecting both SessionContext & WebServiceContext in an EJB 3 Web Service

Hi,
Is it valid/legal to inject both of WebServiceContext and SessionContext in an EJB 3 Web Service, e.g.:
@WebService
@Stateless
public class MyService
@Resource private SessionContext sessionContext;
@Resource private WebServiceContext webServiceContext;
}Thanks in advance.

J2EE and Web Services

Hi forummates,
In the traditional architecture, the communication between EJB is RMI/IIOP. Web Services can be looked as a communication between classes on SOAP/HTTP.
How should we use Web Services in J2EE in the maximum effeciency? Is there any good example of using Web Services in J2EE (1.4 is a must?) ? Please advise.
Lawrence.

Hi Lawrence,
I would look at the J2EE blueprints on web services to get started. You may also want to take a look at the J2EE tutorial and web services tutorial. Links below:
http://java.sun.com/blueprints/guidelines/designing_webservices/

XML and Web Service Data Source Missing in Crystal Reports for VS

I would like to use a Web Service as the data source for a Crystal Report that will be running outside of my Visual Studio application. So setting the data source to the web service in code is not possible. My understanding is Crystal Reports has a connection (in the Database Expert under New Connection) named XML and Web Service. Here you can select web service and enter the WSDL URL for the web service. However it does not appear in the list for Crystal Reports for Visual Studio. Does this connection type come with the Visual Studio version of Crystal Reports and if not is their a way to obtain it?
Thank you for your assistance.

None of the bundled versions of CR have the driver. Reason is that the driver responsible for these connections requires the Java framework and I suspect MS would not be too pleased if we installed the Java framework. The stand alone versions, since they are not part of any bundle can and do install the Java framework and the driver. Note that even the latest release of CR - CRVS2010 does not have the driver as it essentially becomes a bundle or a VS2010 plug-in.
So, the short of it is; you have to obtain a stand-alone version of CR. I'd recommend CR 2008 (12.x) as CRXI R2 will run out of support in June of this year.

Can't run wiki and web services at the same time?

I'm a newbie with Lion Server, but I've been running several web sites successfully for about 6 months. I'm up to Server 10.7.4.
I've been trying ever since the first installation of Server to get the wiki service running. I had absolutely no luck until I turned OFF the web service (always got the "URL does not exist" error when I tried to create a group wiki from inside the Server app). With the web service off, it all starts up fine and I created my first wiki (woohoo). Turning web service back on kills access to the wiki. I don't find reference to this in any of the dicussions, and especially not in Apple's documentation.
Are the Wiki and Web services mutually exclusive? Or is there a way around this?
I'm using Dyndns to provide me with sub-domains to use, and I've dedicated one of them to the wiki service. Traffic comes in on port 8080, where my web sites are on port 80.
Thanks for any pointers...

LR supports tethering using a Canon DLL and EOS Utility probably also supports tethering or at least uses something from a similar Canon DLL. You probably cannot have two different versions of that DLL loaded at the same time, so it makes sense there are problems.

Message Monitoring and Web services Sequences .. SOAMANAGER

When can I use Mesage Monitoring and Sequence Monitoring .
We are making a proof a concept and we are the following.
1. A program which executes a proxy and with this proxy we are consuming a web services.
2. The proxy and web services were implemented in the same Abap Machine .
3. We execute the test and everything works very well and we consume the webservice and the program displays the expected result.
Now want to know How can we use the Message Monitoring and the Sequence Monitoring . Is this posible ? Do we have to make any previous configuration?
We don´t have any XI installation and for that we wonder if we can monitorize the webservices sequences ?
Any idea about if we can realize such king of actions ..
Many Thanks

Hi
I assumes u have dual stack.
You can do the sequence monitoring with or without PI. But without PI you would achieve that thing on the local machine.
You have to do those things at Java End using SAP NWA.

SSL certificates and Web Services Usage inside Oracle Database Questions!

We have implemented a specific business logic using PL/SQL for our client, so we open a file and process each line of this, doing something in the Database and also call a Web Services (Service1) using UTL_HTTP package. Service1 runs in a Windows 2008 Server in the DMZ as Database server.
Service1 is already working, and we can call the service from PL/SQL without troubles.
However, according with security client's policies they requires all Web services be consumed via https including Service1, so we must to follow the procedure established for Oracle in order to enable the calling of service1 via https from the Database.
Our client's DBA and IT Team are concerned about two subjects before to continue to follow the certificate installation:
     - SSL Certificates:
1- Can installed certificates in the Database put in risk the stability of the database?
          2- Can installed certificates in the Database generate performance issues?
          3- Can installed certificates reloading the Databases?
          2- Can installed certificates in the Database generate security issues?
     - Web services:
1- Can web services calling from the Database put in risk the stability of the database?
2- Can web services calling from the Database generate performance issues?
3- Can web services calling from the Database generate security issues in the DMZ?
Could you please give us any clues, about the possible negative impact related with the SSL certificates and Web Services Usage inside Oracle Database, if it’s the case this impact exists?.
Those are the links describing the procedure mentioned above.

Thiago:
You are correct in that there should be no problem interacting with a Web service that has an HTTPS endpoint as long as you create a wallet and specify it when you make your UTL_HTTP calls, like the PayPal example.
I am not aware of a PL/SQL utility to create a XMLDsig Standard message, but if you find some Java source out there that does it, you may be able to follow a technique I used for a similar use case:

Custom Portal Services and Web services

Can you please tell me what exactly are "custom portal services" and "web services" with a business like/ real life example?
How do you go about developing deploying and utilizing these services in Portal?
Thanks.

Hi navin,
Thanks for the par file.
Duly awarded points.
I need your help again.
I wish to use the method
public String getWelcomeString(String name)
in my own portal application to test usage of portal services.
So I uploaded your par file on my server.
Then I added the api and core jar files which came along with your par in my project as external jar files.
I imported com.wickes.WickesService.*;
Next, to use the service I coded:
IPortalRuntimeResources rs =
PortalRuntime.getRuntimeResources();
IWickesService ws = (IWickesService) rs.getService(IWickesService.KEY);
But now I am stuck and I dont know how to proceed.
Please help.

Enterprise services and Web services

Hi Everyone
I need documents about Invoking enterprise services from Netweaver PI and web services from Netweaver PI, I can find only NetWeaver CE, but not PI. So help, any links?? or pdfs?? or ideal would be some demo example of invoking a web service using PI.
Thank you

GTC Connector using SPML Format Provider and Web Services Transport Provide

Hello All,
Did any body create a GTC connector which uses SPML Format for Format Provider and Web Services format for Transport Provider?
Is there any doc which talks about the same?
I need to provision to a system over web services and I thought GTC using the above formats should be an easy approach. Am I right?
I was trying to follow:
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e14309/devgtc.htm#BABDFDFE
But Iam getting lost in the immerse details.
Thanks in advance.

Hi ,
I tried creating one and am getting the following error while provisioning:
SPML Response failed V2 schema validation
Th eoracle document says :Ensure that the SPML response returned by the target system conforms to the SPML V2 standard specification
Please help me with the same. What is it that needs to be done here.
Thanks

Many Thanks

hi,
short answer: you can't. to my knowledge there is no such thing as message/sequence monitoring outside of PI/XI.
the only thing you can do is to enable debugging and access some debugging info from ST22. other than that you do not have access to the original (XML) message, the HTTP headers or the ST(simple transformation) info or anything else.

anton

Struts and web services

If you want to use Struts and web services, what approach do you take? If you want to use reliable messaging,
you need to have a web service client as well as the web service being called.
What is the recommended way to set this up?
Do you call a local web service from the action class and then have that web service do all of the business logic including calling remote web services?
I am just starting to look at this so I am probably not close but I would like some guidance on what, in general, is the correct approach.

The jars you are referring to are not SAP BusinessObject specifics jars: struts and JiBX. There are open source java framework. For more information about the struts refer to:
http://en.wikipedia.org/wiki/Apache_Struts
for more information about jibx refer to:
http://en.wikipedia.org/wiki/JiBX
Normally the core jars for a SAP BusinessObjects webservice SDK are:
The core jar files to use for Web Services Java SDK applications are:
dsws-bicatalog.jar
dsws-biplatform.jar
dsws-common.jar
dsws-publish.jar
dsws-queryservice.jar
dsws-reportengine.jar
dsws-saveservice.jar
dsws-session.jar
wilog.jar
And the jars you have mentioned are part of the
The dependent jar files to use for Web Services Java SDK applications are:
activation-1.1.jar
axiom-api-1.2.5.jar
axiom-impl-1.2.5.jar
axis2-kernel-1.3.jar
axis2-saaj-1.3.jar
axis2-xmlbeans-1.3.jar
backport-util-concurrent-2.2.jar
commons-codec-1.3.jar
commons-httpclient-3.0.1.jar
commons-logging-1.1.jar
log4j-1.2.14.jar
mail.jar
stax-api-1.0.1.jar
struts.jar
wsdl4j-1.6.2.jar
wstx-asl-3.2.1.jar
xbean-2.2.0.jar
XmlSchema-1.3.2.jar
In any cases it is recommended not to have duplicated jars in your deployment and also check if the version of the jars to use is supported by the version of the JDK used.
Thanks
