EP 6.0 SP3/Web AS 6.40 JAVA:

I want to install the Portal Platform EP 6.0 SP3.
After installing Web AS 6.40 JAVA SP3, can we directly upgrade to the highest SP level?
The install guide for the EP 6.0 on Web AS 6.40 mentions the following sequence:
Web AS 6.40 JAVA SP3 -> Web AS 6.40 JAVA SP4 -> EP 6.0 SP3 -> Web AS SP9 -> EP 6.0 SP9
The link from the SDN:
Install SAP EP 6.0 on Web AS 6.40
mentions the following sequence:
Web AS 6.40 JAVA SP3 -> Patch Web AS 6.40 JAVA to latest SP -> EP 6.0 SP3 -> Patch EP 6.0 to latest SP
My platform: Solaris 9, 64-bit mode, Oracle 9.2.0.5
Any thoughts?
Kind Regards,
Phani.

Nick,
I understand the part that Web AS 6.40 SP09 comes with SR1. I would like to know the recommendations for existing systems that already have a Web AS 6.40 SP3 installed.
Phani.

Any difference in creating a web service from a java class or session bean?

Hi,
The JDeveloper tutorial at http://www.oracle.com/technology/obe/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm demonstrates creating a web service from a plain java class. I'm wondering:
- Is it possible to create a web service from a stateless session bean instead of a java class? If so, what's the proper way to do this in JDeveloper? When I tried doing so in JDeveloper 10.1.3.0.4 (SU5) using the J2EE Web Service wizard, the wizard did not list the session bean in the Component To Publish dropdown (it does list any java classes available in the project). I can proceed by manually typing in the name of the session bean. After the wizard completes though, the @Stateless annotation that had been in my session bean class code is removed and replaced by a @WebService annotation. The end result is that it looks like it made no difference whether I had tried to create the web service from a session bean or plain java class as the annotations in the resulting web service code are the same (although if I had started from a session bean, the class for the web service still implements the Local/Remote EJB interface that the session bean originally implemented).
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean? I'm creating the web service from scratch so I also need to either build the java class or stateless session bean the web service would be based on from scratch too.
Thanks for any ideas about this.

Hi,
EJB Session beans (EJB 3.0) are deployed as WebServices by annotating the class with @WebService and the methds with @WebMethod (both tags require you to add the JSR-181 library to your project (available in the JDeveloper list of libraries)). Unlike the J2E WebService, the EJB session bean service is turned into a WebService upon deployment. This means you obtain teh WSDL file after deployment
- Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean?
The difference is that EJB Session bean based web services are integrated with the J2EE container, which means that they can leverage container services like transaction handling, data sources, security, JMS etc.

Invoking a AXIS Web Service with a Java object as input argument

Hi
I've been trying to execute a bpel process that invokes a web service deployed through axis.
This web service takes a java object as input argument as opposed to data types that are directly mapped to java types through the SOAP engine.
I deployed and tested the service outside of BPEL using a test client class. Everything works well.
When I try to configure the "Assign" and "Invoke" activities so that service can be invoked, I cannot see the data structure through the variable picker and I see the following message:
"The element {urn:ComplexTypeWebService}TimeSheetBean is not know to the schema container. Perhaps a schema file that uses it needs to include or import its definition.There mat also be an XML schema issue (non resolvable schema) which prevents {urn:ComplexTypeWebService}TimeSheetBean from being seen by the schema processor."
Is there any example that demonstrates how to invoke an axis web service in such scenario? What am I doing wrong?
Please, let me know.

The passing of Java objects in and out of a web service is NOT supported. variables must be xml documents defined by a XML schema. In my opinion, missing Java object and WSDL is not a good idea. -Edwin

Issues in invoking a web service from a JAVA/BPEL client...

We are trying to invoke a web service from a JAVA/BPEL client using org.apache.soap classes. But everytime we are running into issues of IllegalAccessError or InvalidClassError or IncompatibleClassError based on different jars we are trying to include in our project. Attached is a simple BPEL project which tries to invoke a web service through JAVA embedding (no supporting jars need to be included explicitly). It erros with following trace:
Class org/apache/soap/Envelope violates loader constraints
     Invalid class: org.apache.soap.Envelope

Could you please help us out or provide any pointers. Any help would be highly appreciated

Because you weren't told what to get, perhaps you already have it eh?
What you want to read up about is JAX-WS, which is the webservice API bundled by default with your JDK (Java 6 and up). You'll find the wsimport tool in the bin directory of your JDK. I recommend you explore that directory and read up about all the executables you can find there, to be more prepared in the future. Know the tools you work with and all that. Most tools have a manual on this website:
http://www.oracle.com/technetwork/java/javase/tech/index.html
(under tools and utilities). Not wsimport, that is part of the jax-ws documentation. Better you look for jax-ws tutorials using Google, it will be quicker.

Invoking a web service from a java code

Hello
I created a simple Web service using JDevlper. It contains two methods
1) getInf int () {
return inf;}
2) void setInf (int a) {
inf = a;}
I have deployed it on Oracle Application server. By inserting the address in a browser, I tried both methods and it works correctly.
Here I am looking how to invoke this web service using a java client and use the method setInf (5 ) / * for example * /.
I search but I have not found an answer that works :(. I hope you could help me to solve this problem.
Thank you in advance

How do i Hyperlink to a web page from a java application?

How do i Hyperlink to a web page from a java application using internet explorer as my default web browser?

It's very simple.You can start any Application with the class Runtime. The command is an array consisting of the path of .exe and the file to be open.
String [] cmd={path of IE+Filename.exe,"URL of your website"}
try
Runtime.getRuntime().exec(cmd);
catch (Exception e)
System.err.println(e.toString());
}

How many web.xml in a java application

1Why ?Because the Web container refers to only one web.xml for one web application.
I havent heard of an application having more than 1 web.xml
How?It reads all the definitions of servlet mappings, filters, welcome-file etc from this file itself.
Where?From the following folder ...
/WEB-INF
By the way ..... the way you questioned me was amuzing ... Why? How ?Where ? Its funny :D

Calling a soap web service from a java desktop application

Hi,
Does anyone know how to call a soap web service from a java desktop application? I've seen examples using Apache Axis, but it sounds like Axis needs to run on a web server and we are trying to avoid that. My initial thought was that, "of course we need a web server", but I'm wondering if there is a way to do this without a web server.
Any help is greatly appreciated.
thank you,
Julie

If you are the consumer you don't need any web server. The web server is only needed in the provider end.
In java 6 there is a built in framework to call web services without the need of third parties (such as apache axis)
take a look at:
https://jax-ws.dev.java.net/guide/Developing_client_application_with_locally_packaged_WSDL.html
http://java.sun.com/webservices/technologies/index.jsp
For the provider end there is also a built in http server to expose web service via HTTP without the need to
use any external web server.
take a look at:

Web dynpro abap or java ?

Hi All,
Our client wants a web front end for the SAP system and has asked us to search which web dynpro ABAP or Java will be suitale ?
They were of the opinion that web dynpro for ABAP is not that good for web interfaces is it correct ?Also is there demend for web dynpro developers in the market ?
Thanks & Regards
Gaurav Jain

>They were of the opinion that web dynpro for ABAP is not that good for web interfaces is it correct ?
What do you mean by Web Interfaces? Web Dynpro ABAP and Java are well suited for created browser-based (or rich client based) business application User Interfaces. If by Web Interfaces you mean Internet facing, highly customizable user interfaces - then no - neither web dynpro abap or java are really well suited for that situation. WDA and WDJ are both designed to create consistent Business Application user interfaces.
Now if you just want to compare WDA and WDJ - that is a very different question. The differences in capabilities are relatively minor. Generally it comes down to which programming language you have more of a skill set in and how close to the underlying data you need to be. Also are you planning to extend existing SAP applications? WDA is primarily used by SAP within the Business Suite (ERP, SRM, PLM, etc) - two exceptions however - WDJ is used in ESS/MSS (although newer portions of that solution are in WDA) and CRM uses BSP/CRMUI. WDJ is used by the middleware components (Portal) and edge or composite applications.

ABAP Web Dynpro V/S JAVA Web Dynpro

We need to pick developing technology between ABAP Web Dynpro v/s JAVA Web Dynpro. Is technology better than other in terms of security, scalability? There is lot of documentation on the web but it is very old and out dated. I am pretty sure things have changed quite a bit with recent versions of SAP. Any feedback is greatly appreciated.
Thanks.
PS: I Used Web Dynpro for ABAP at my previous client for SAP SRM without a problem.

Dear Sap Fan
This has been a long and interesting debate on SDN.
You will find plenty of posts discussing this matter.
But there's no clear winner, I warn you.
;o)
This one in particular is very good:
[http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/e0e4940c-035c-2b10-0b9d-eb8f99674f4e]
But you can also check these others:
[webdynpro java or abap;
[Webdynpro Java or ABAP;
[Webdynpro Java or ABAP;
[Webdynpro Java or Abap ?;
More and more you see clients migrating from WD4J to WD4A.
Guess SAP is also heading into that direction, perhaps because Oracle bought SUN sometime ago.
I'm comfortable on both environments I have to say.
I have more than 10 years with development.
I know ABAP from inside out.
I also know JAVA and I'm certified with this technology.
But I personally prefer WD4A.
Why ?
Because you don't need to use NWDI.
Because you don't need to configure JCO's.
Because you integrate seamlessly the development with the transport framework (requests, etc..)
Because debugging is great.
Because plenty of traditional ABAP tools (trace, logs, performance analysers, etc..) can also be used with WD4A
Because you don't need to worry with NWDS...just type SE80 and you're there... ;o)
And I could go on and on....
But then again, it all depends:
Do you have a lot of good in-house JAVA knowledge ?
Do you use a lof of Custom JAVA development in your company ?
Are you planning to use standard SAP (ESS/MSS or others for example) ?
I'm not saying that WD4A is "better" than WD4J.
There's no such thing.
Each option has its pros and cons.
You also can't tell that WD4J is more secure or scalable than WD4A. Or the opposite.
And, believe me, WD4J is still going strong with a lot of customers.
But things are changing, and for me WD4A would make more sense if you want to be aligned with SAP.
Now and in the future.
Kind Regards

Finding an EJB object. Web clients vs. Java clients

From what I've read this is the process for a web client to find an EJB object: the client uses JDNI to find a reference to the EJBHome interface and then it uses the create method from this interface which makes the container to begin to work, creating an instance of the implementation class and an instance of the EJBObject interface, and returning a reference to the EJBObject, which will be used by the client to call the methods.
Are there any differences if the client is a java application and not a web client?

The Java Client talk to the server with random ports
not 80. Gives me a headache. _*why?
There's no need to get headaches about it, in fact no need to worry about it at all.
Just have the JNDI services available so you can do the lookup (which might require opening a port (or more than one) on the firewall, but that's it.
And that's no different between a standalone client and a web application client. Both need to do that JNDI lookup.

Diff in web dynpro abap and Java

Hi Friends,
   I am new to web dynpro ABAP and Java.
     1) Please give me idea about about these two
      2) In which Scenarios these are helpfull
     3) From which version   onwards these are existing
Thanks for your help.
Thanks,
Asha

Hi Ravi,
The following are basic differences between ABAP and JAVA WD.
1. ABAP WD can be developed in ABAP Workbench thru transaction SE80 whereas Java WD needs SAP NetWeaver Developer Studio.
2. Since ABAP WD is a part of the ABAP Workbench, it has direct access to ABAP dictionary. Hence access is faster.
3. In order to develop on ABAP WD, you will need basic knowledge of ABAP objects, whereas in Java WD, dev is using Java
