Log for J2EE Web Services?

Hi All,
My SAP Web Application Server has some Web Services.
The Web Services are being run from the same server (Web Dynpro/Java Projects).
Is there a <b>built in</b> log which holds data of the calls?
Info like request/response, HTTP codes etc...
My J2EE version is 6.14, soon will be upgraded to 6.19.
Regards,
Omri

Thanks for the answers.
I've found <a href="http://help.sap.com/saphelp_nw04/helpdata/en/60/aec0b110a940d09e7a296c09af27bf/frameset.htm">this</a> in help.sap.com.
I did the config in 'Log Configurator' and log file should be
./log/services/webservices/runtime/sap.com_WS/Hello.trc
I changed the severity to 'ALL' and run the service a few times (through Web Service Navigator & a Web Dynpro application)
I looked for 'Hello*.trc' files but I couldn't find any.
So what is the correct way to configure it?
I've checked the 'regular' config files (DefaultTrace, applications etc) but they don't contain the data I need.

Omri

How to disable default logging for workshop web services

Hi there,
We have created a web service using WL Workshop that we want to deploy to a production server. The problem is that the destination server is not using a default log4j library for the server, but each application initiates its own library.
When we try to deploy the web service onto the production server, we are getting an error of a log4j/Appender class not found. We can solve the problem by adding any log4j library to the class path at the beginning, but that will cause compatilibity problems with existing applications.
Is there any way to disable the default web services logging? It looks like the knex library is trying to instantiate this class at deployment. Any way we can disable that option?
Thanks

Thanks David for your reply,
That is indeed what I am trying to do: to add all required libraries within my web-inf folder.
But it seems that the server itself expects the log4j library to be loaded when the server is initiated. It looks to me that some server-level listener for the web services is starting together with the domain and tries to access the log4j library. This library is not found because it is inside the web-inf folder of my application.
I do not see any error while starting the server. The error only appears when trying to deploy the application (ear) with the web service. It seems that I am forgetting something, but unless I include the log4j.jar in the classpath when I start the server, i will not be able to avoid the error.
Suggestions and tests are much welcome.
thanks!

How to create stub for C++ client to invoke a j2ee web service

Hi All,
I have developed a j2ee web service which is deployed in Tomcat. I have to call this service from C++ client. I have followed "Axis C++ Client User's Guide" to create stub for my service. I am running WSDL2Ws tool with command
D:\axisserver\axis-c-win\wsdls>java -cp %AXISCLASSPATH_C%; org.apache.axis.wsdl.wsdl2ws.WSDL2Ws Calculator.wsdl -lc++ -sclient. While running this WSDL2Ws tool , it is giving error.
Exception Stack is as follows.

Anybody can suggest me what i missed...
Thanks in advance...

Hi all,
I have solved this issue. I had JDK1.3 by default. So it was giving error. When i use java from jdk1.4, it created stubs for web service. Java version was the problem. Now it is working fine.
Thanks....

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

NullPointerException in Create J2EE Web Service Wizard

I created an EJB2.1 session bean that has a method which returns an user defined class and also throws user defined exception. I tried to use the Create J2EE Web Service and chose to use RPC/Encoded scheme.
The WSDL and java-wsdl mapping files were generated, but I got the following messages and exception. The webservices.xml and oracle-webservices.xml were not generated and wizard did not finish. Any ideas why would this happen?

Error while returning complex data type in a J2EE web service

Hello,
I am implementing J2EE web service which returns array of custom class object.
I have implemented serializable interface to custom class, and also to session bean.
But it gives the following error:
Serializing object [Lcom.ltitl.j2ee.ejb.classes.ProjectDetails;@2a2289 fails. Nested message: XML Serialization Error. Object of Class [com.ltitl.j2ee.ejb.classes.ProjectDetails] does not have property [ObjId] of type [java.lang.Integer]. Check if the right object is passed to the serialization routine..
As error stated about some property ObjId..I tried including such property in my class. But now it gave exception while deploying stating that ObjId already defined.
Also I want to return multiple arrays of complex custom classes. i tried using vectors but didnt work. What is the method to return arrays of complex custom classes.
Please help..
Abhijeet

Trying to create a web service that returns a Collection doesn't seem to be possible in Netweaver. The reason for this is that languages other than Java have difficulty in mapping Collections, amongst others, to their own native equivalents.
There is a discussion on the subject here you may find useful:
http://forum.capescience.com/showthreaded.php?Cat=&Board=webservices&Number=147&page=0&view=collapsed&sb=5&o=&vc=1
The short answer is to use object Arrays instead, or a custom class that contains an array of each type of object you would expect to find in your Vector
Hope this helps

J2EE Web services and JAX-RPC

Hello..
While working with J2EE web services using JDeveloper and OC4J, I noticed that it really doesn't confirm to Sun's JAX-RPC standard. The Web Service interface class does not extend the "Remote" and all methods don't throw "RemoteException" as mandated by JAX-RPC standard.
I have few questions:
(1) Are the OC4J J2EE web services completey different from JAX-RPC based web services.??
(2) Does Oracle have any implementation of JAX-RPC??
(3) Is Sun the only one promoting and implementing the JAX-RPC standard? Or are there other players?
thanks...

(1) Are the OC4J J2EE web services completey different from JAX-RPC based web services.??
OC4J J2EE Web Services originate from Oracle/Apache SOAP with several differences:
a. A model where each type of implementation gets a specific servlet (e.g. one for EJB's, one for PL/SQL, one for stateless and stateful Java classes. Architecturally, you can see the picture here:
http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/b10004/orawebservices.htm#1024808
(scroll down a half page for the picture)
b. The packaging of the Web services rather than using the Apache SOAP registration mechanism uses something closer to JSR 109 (also known as Web Services for J2EE, part of J2EE 1.4 with JAX-RPC, SAAJ [SOAP API forAttachments in Java] and JAXP [Java API for XML Parsing]), where the Web service is packaged as an ordinary ear file for deployment.
Oracle built this implementation by extrapolating from the JAX-RPC documentation that was available last year before it was a final specification in an effort to release a production quality Web services implementation that was aligned with JAX-RPC. It has been through two releases - Oracle9iAS 9.02 and Oracle9iAS 9.0.3 and is now being evolved to JAX-RPC as we move to J2EE 1.4.
(2) Does Oracle have any implementation of JAX-RPC??
We are planning to release a JAX-RPC implementation in the new year (I don't have specific dates yet) on OC4J. The production implementation of this will be as seamless a migration as possible from the existing implementation. Oracle9i JDeveloper will also add support for JAX-RPC as a 3rd option in its list of choices available. You can get a sense of how such a migration would work by running the Web services wizard in JDev for Apache SOAP and then, in a separate project, running it for Oracle9iAS J2EE Web Services - imagine there being another option for JAX-RPC. The work to migrate should be as simple as running a wizard or command line utility (known as the Web Services Assembler tool in Oracle9iAS).
(3) Is Sun the only one promoting and implementing the JAX-RPC standard? Or are there other players?
Pretty much every one in the Java side of industry will be implementing JAX-RPC. The important time to note is when J2EE 1.4 is released ... sometime in the new year ... I believe around March but may be mistaken. Part of J2EE 1.4 is required support for JAX-RPC, SAAJ, Web Services for J2EE etc etc. This will standardize the implementation of Web services. Oracle, like others in the industry, supports the standard protocols, (SOAP), interfaces (WSDL) and registries (UDDI) - what J2EE 1.4 does is standardize the packaging, deployment and implementation (the wrappers generated by the tooling).
My guess is that around JavaOne (June 2003) there will be a rash of announcements from J2EE vendors announcing support of JAX-RPC and J2EE 1.4 (or early implementations) as we will be in the same race that happened in 2001/2002 when J2EE 1.3 was the spec to announce implementations around.

J2EE web service client using WSDL

Hi,
We are required to develop client program in Java for the
web services developed in SAP XI 2.0.
We will be getting the WSDL files for corresponding web
services.
We have tried doing it with J2EE JAX-RPC...
We studied the sample program of HelloService...
While calling the service from command line..it takes .jar file..
But we have to make use of only WSDL....
Is there any alternative way?? or jax-rpc is the best one???
wat will be the best way to do so??

Hi,
thanx for your reply!
We have written web services in SAP XI 2.0....
we has generated corresponding WSDL..which is little
incomplete..but we can modify and update it according to
requirements...so we have complete WSDL....for corresponding web
services.
My colleagues have developed web dynpro application which
makes use of those services. Now for demostration purpsoe we need
to write java/jsp which will access those services...
can u help???

Deploy a J2EE Web Services App in CE 7.1 SP1 SDN Preview

Hi,
I am new to SAP CE 7.1 SP1 (SDN Preview). I have a SAP J2EE (web services) application developed for SAP Netweaver 7.0.
How to deply the application in CE 7.1 SP1.
thanks in advance,
Nagarjuna.

Hi Nagarjuna,
the easiest way will be to use the Deployment perspective in NWDS. Just choose Window > Open Perspective > Other > Deployment.
If you have the application packages in a deployable archive (EAR, SCA, SDA, ...) in the file system, right-click External Deployable Archive and select Add. You can also choose archives to be deployed from the workspace.
If your application cannot be deployed or doesn't run properly, you might have to make some changes to it in order to port it from NW 7.0 to 71.
Other methods of deployment:
- There's a program called JSPM which is aimed primarily at non-development, admin users (the guys running the production system).
- There's a command-line deployment tool - have a look at <Install drive>\usr\sap\CE1\J00\j2ee\deployment\scripts.
Cheers,
Thorsten

Thamarai,
Can you provide more information on your jws ? Also can you start the server
from the command line with verbose option. This will cause
weblogic_debug.log to be generated in the domain folder.

Deploying ADF BC as J2EE Web Service

I am attempting to deploy some ADF BC components (just the data model) as a J2EE web service. In the Application Module Editor I have selected the "Remoteable Application Module" and selected the "J2EE Web Service" option. Some of my public methods that I have exposed on the Client Interface (which return primitive types or serializable complex types) of the AM are placed into the WSDL of the web service. I would like to return a representation of one of the View objects and understand since the view itself is not a serializable type, I cannot return this directly. I created a public method on the Application Module that returns a RowSet (which I grabbed from the view) and it allows me to put that method on the Client interface but it does not show up in my web service. Is there anyway to directly return a representation of the view without manually retrieving the data and placing it in a custom class/bean that I return and then have to turn back into a view on the calling side?
Thanks for any help

Hi,
exposing a VO as a WebService will come a s a feature in JDeveloper 11. Until then you can only expose methods

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
Ram
