JAX-RPC vs OC4J J2Ee web service

Hi,
Currently we use Oracle10G 10.0.3 developer preview edition. we deployed same web service on both JAX-RPC platfrom and OC4J J2EE web service platfrom (RPC encoding style). We found that old platform seems to perform better than JAx-RPC platfrom with regard to serialization and de-serialzation. We also did the test on Doc/literal style in JAX-RPC platfrom and its performance is not as good as the one deployed on old platform. We understand JAX-RPC is new implementation and Oracle10.0.3 is under developer preview edition and so it may not be optimized. We have following questions
1. Is this a known issue in JAX-RPC platform?
2. Is there anyway to optimize JAX-RPC web service? Like using different XMl parser (instead of Oracle XML parser)
3. When is the final release of 10.0.3 expected?
4. Will Oracle be supporting old web service platfrom (OC4J J2EE web service platform)? If so how long?
Thanks and regards

Using JAX-RPC handlers to proxy web service traffic

Hi,
I want to use JAX-RPC handlers to proxy web service traffic. In some instances the handler should modifiy / verify the message before forwarding the request to the remote web service end-point. Hence, the handler should forward the call by invoking the remote web service. In some cases the result from invoking the remove service should be post-processed by another proxy handler. To ensure that the result from invoking the remote service is available for post-processing I assume that the handler invoking the remote service must add the response message to the message context ( e g setProperty method) in the handler. Is this correctly understood?
I would like to understand that this is a technically feasible and reasonable approach of using JAX-RPC. I'd really appreciate some feedback here.
Many thanks,
Tom

Hi Eric,
Thanks for your response. we are trying to access WSRR( manages end point urls for 7 different environments) and generate the end point dynamically at the design time. As we figured out WSRR is not compatible with OSB we are trying to implement these client side (OSB Proxy service) handlers which would get the dynamic endpoint depending on the environment used. I was able to create the handlers for this and set the jar in the classpath but the client service which should be using these handlers have to have these handlers defined in the deployment descriptor(web.xml) which am unable to see with a OSB project.
Will there be a deployment descriptor(web.xml/webservices.xml) associated with Proxy services on OSB? Or Is there any other way to add custom JAX-RPC Handlers to a proxy service? Or is there any way to connect to WSRR directly?
Thanks,
Swetha

JAX-RPC And Non-Java Web Service

Hi,
This is a total shot in the dark. I'm attempting to consume an RPC web service developed in Delphi. I've created a JAX-RPC client in NetBeans from the published WSDL, attached below. I've created calls to several of the procedures available. What's bizarre, at least to me, is that half of them work fine and half of them don't. In all cases where they don't I'm getting a returns SOAP envelope indicated an access violation, attached below. There are no errors in any of the server logs and the developer assures me that the procedures do, in fact, work from his client (also developed conveniently enough in Delphi).
I'm willing to take him at face value for the moment and assume that the problem is in my client implementation, although I have no idea where it would lie. The only difference I've been able to gather between the features which work and those that don't is the size of the return package...it would most likely be much larger than the ones that don't work.
The service is an ISAPI dll running under IIS on Windows Server 2003. Any clues or guidance anyone would be willing to provide would be most welcome. On to the files:
There wasn't enough room to post the entire thing so I've included one working (CheckStock) and non-working (GetLibTrace) function.

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.

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?
Web Service Log :

JAX-RPC on OC4J (Migrating from TOMCAT to OC4J) Problems

I am attempting to compile and build a simple web service
to using wsdeploy from Sun's JWSDP1.2. It works fine on Tomcat but when I try to deploy it to OC4J. I get the following error:

I've come to notice that Oracle's WebServicesAssembler doesn't use com.sun.xml.rpc.server.http.JAXRPCContextListener but instead uses something else. When the JAXRPCContextListener starts to initialize it trys to perform the following operation:
classLoader = (URLClassLoader)Thread.currentThread().getContextClassLoader();
Is there any way to remedy this?? Or is there anything I can do to get this to work??
Thanks
Mike

Have you deployed JAX-RPC onto OC4J? We currently do not have JAX-RPC available on OC4J.

Web Service/XML-RPC: SMTP to BC4J web service bridge ??

A new business problem just landed on my desk for a possible solution.
One way XML documents coming in from a Novel mail server doing SMTP forward to something
in the OC4J, BC4J, side to receive and parse the XML.
It would be great of course if the JDev / OC4J web services tools had a SMTP service
that would route inbound SMTP messages at email address to a particular Servlet.post().
Any other ideas??
Thanks much,
curt

I don't have answer for the SMTP binding as currently the Oracle9iAS J2EE Web Services engine doesn't support an SMTP binding (checking with product management to see if their is any solution today). I suspect this is a manual exercise parsing the SMTP message and extracting the SOAP message.
However with BC4J you do get in Oracle9i JDeveloper 9.0.2 the ability to consume/publish SOAP messages. And the readXML and writeXML methods on the BC4J view objects help deal with the content of your SOAP messages. So some of the work has been done for you.
If you haven't seen this already, here is what the publishing side looks like. First, if you build a remote method in your <applicationModule>impl.java file with a signature like (everything in "<xxx>" is specific to your implementation), you can publish it as a Web service. For example:
import org.w3c.dom.*;
import oracle.xml.parser.v2.*;
public org.w3c.dom.Element getBC4JXMLDocument (String parm) {
get<some BC4J view>().setWhereClause("<some column from your BC4J view>" = parm);
// Assuming your column is a String :-)
get<some BC4J view>().setWhereClauseParam(0, parm);
return (Element)get<some BC4J view>().writeXML(1,Row.XML_OPT_ALL_ROWS);
Then publish the application module method as a Web service (see: http://otn.oracle.com/products/ids/daily/may10.html)
It is pretty easy to build a client from the WSDL that is generated using the JDev wizards. Once you have the stub your code would look something like:
import org.w3c.dom.*;
import oracle.xml.parser.v2.*;
org.w3c.dom.Element x = stub.getBC4JXMLDocument("your_parameter");
XSLProcessor l_processor = new XSLProcessor();
XSLStylesheet l_xsl = l_processor.newXSLStylesheet(this.getClass().getClassLoader().getResourceAsStream("some.xsl"));
l_processor.showWarnings(true);
l_processor.setErrorStream(System.err);
DocumentFragment l_result = l_processor.processXSL(l_xsl,(XMLElement)e);
// now feed the transformed XML document into the receiving BC4J view object using the readXML method
The neat thing, which I think is the gist of your message, is that you could then use the BC4J readXML message to parse the incoming XML message and inflate it back into a BC4J view object. The net result would be moving an entire dataset over SOAP to a BC4J client.
The SMTP binding would have to worked into the stub code generated. I don't have sample code that would help here right now but will check around.
Mike.

Adding Jax-RPC Handlers to OSB Proxy Service

Hi All,
I am new to OSB and wanted to know if I can add a Client side (My proxy Service -> external business service) Handler chain to OSB Proxy Services. I know how to add handlers to general webservice. But is there any way to intercept the request by adding handlers to OSB proxy service before it goes to business service?
Any help is highly appreciated.
Thanks,
Swetha

Hi Eric,
Thanks for your response. we are trying to access WSRR( manages end point urls for 7 different environments) and generate the end point dynamically at the design time. As we figured out WSRR is not compatible with OSB we are trying to implement these client side (OSB Proxy service) handlers which would get the dynamic endpoint depending on the environment used. I was able to create the handlers for this and set the jar in the classpath but the client service which should be using these handlers have to have these handlers defined in the deployment descriptor(web.xml) which am unable to see with a OSB project.
Will there be a deployment descriptor(web.xml/webservices.xml) associated with Proxy services on OSB? Or Is there any other way to add custom JAX-RPC Handlers to a proxy service? Or is there any way to connect to WSRR directly?
Thanks,
Swetha

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

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.
Exception in thread "main" java.lang.NoSuchMethodError
at org.apache.axis.wsdl.wsdl2ws.info.Type.<init>(Unknown Source)
at org.apache.axis.wsdl.wsdl2ws.info.TypeMap.getType(Unknown Source)

at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.generateWrappers(Unknown Source)
at org.apache.axis.wsdl.wsdl2ws.WSDL2Ws.main(Unknown Source)
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....

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

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

Web services - JAX-RPC/Axis/OC4J

Hi,
We are planning to expose some of J2EE applications as web service. It is based on JAX-RPC 1.0. I have checked it with Apache-Axis without changing any code and it worked. Will it work in OC4J without any code changes?
1. Does OC4J or Oracle SOAP server supports(or implements) JAX-RPC?
2. Do we need to change any code?

Right now we have a JAX-RPC 1.1 with JSR 109 support preview here on OTN at - this came out at OracleWorld:
http://otn.oracle.com/tech/java/oc4j/1003/content_preview.html
The target production date is summer 2004. There are also plans to do another drop of this preview with updated support later this year and possibly again before the production release.
We have quite a lot of functionality that we are targetting to flesh out our Web services support in the areas of reliability, orchestration, transactions and security.

Deploy J2EE Web Service with otherwise than SUN1AS

Right now i have a webservice up and running on a Sun1 that comes with J2EE1.4 tutorial.
But if i try to deploy the war to other AS (say OC4J), saving the web.xml transformed to 2.3, the call to this WS fails because it says the Servlet is not a Servlet (wich is quite right). So, what is going on?
Can't I deploy a WAR containing a WS generated with deploytool to other AS?
Thanks and thanks again,
Mariano.

Things I've learnt these days.
1-) J2EE is still too new for many Application Servers.
2-) Developing web services is a tough, long way to go.
I finally realized war's containing web services are not that portable at all.
I had to download Jdev's 10g preview in order to deploy 1 miserable JAX-RPC web service in OC4J.
And I still can't return a java.util.HashMap in the service's response...not to mention trying to add its mapping in JDev's web service creating process...
So, hold still gentleman, for it's rough.
Thanks,
Mariano.
