BPEL & Oracle J2EE Web Services

I have only tested with success invocations to JAX-RPC
web services.
When I try to call an oracle J2EE rpc/encoded web service
I get a runtime error:
BPEL Fault: {http://mypackage4/ws_hola.wsdl}org.apache.wsif.soap.fault{org.apache.wsif.soap.fault.object=No Deserializer found to deserialize a 'http://mypackage4/ws_hola.wsdl:quien' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'. [java.lang.IllegalArgumentException]}
Does anybody know why?

Hello 2087,
try to add support for xsi type in "bpel.xml" of your bpel process
Example:
<?xml version="1.0"?>
<BPELSuitcase>
<partnerLinkBinding name="PartnerLinkName">
<property name="wsdlLocation">services/PartnerLinkNameWrapper.wsdl</property>
<property name="sendXSIType">true</property>
</partnerLinkBinding>
For more information see the link in this forum:

When i instantiate process from bpel console - everything is ok .. but when i call process from plsql function, i get this error:
ORA-20000: soapenv:Server.generalException - Missing BPEL archive file.
The process domain cannot locate the BPEL archive for process
"AuthorizeKeyCode", revision "AuthorizeKeyCode".
If you have deployed the process please check that it is located in the
directory "/ora/bpelpm/integration/orabpel/domains/vinves/deploy".
; nested exception is:

Hi,
I am trying to invoke the HelloWorld BPEL process from Oracle DB using the demo_soap package downloaded from oracle.com.
Find the PL/SQL block below:
DECLARE
req Demo_Soap.request;
resp Demo_Soap.response;
zipcode VARCHAR2(100) := 'Suresh';
BEGIN
req := Demo_Soap.new_request('initiate',
'xmlns="http://xmlns.oracle.com/HelloWorld"');
Demo_Soap.add_parameter(req, 'HelloWorldProcessRequest', 'xsd:string', zipcode);
resp := Demo_Soap.invoke(req,
'http://nooslux037t.gl.2wglobal.com:7777/BPELConsole/Dev/displayProcess.jsp?processId=HelloWorld',
'http://xmlns.oracle.com/HelloWorld');
END;
Please help me in knowing what value i should pass for the
1. New_request procedure
2. Add_parameter procedure
3. Invoke procedure.
The HelloWorld is same as the example in the BPEL Tutorial Session 1.
Thanks for your time.

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

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?

Not sure what to call the server - this works okay when I'm not using tunneling and using our proxy server??

I think your problem is that you have a proxy user/password and the TCP Monitor (both the command line and built-in 9.0.3 version) do not support that - they only support specification of the proxy server itself :-(
It is a feature request that I hope will make it into the late spring/early summer release of JDeveloper - I wrote it up as a request based on the number of folks who faced this issue with these tutorials.

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.

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

Issue: BPEL invoking Axis web service

Hi
We are calling a Axis web service from BPEL.. The web service has been defined to be a request only 1 way service. The axis service takes around 3-5 minutes to complete the job( data insertion in DB).. But seems like when BPEL invokes the web service; BPEL thread is waiting (thread is not released) and the BPEL process does not move forward until the web service completes the job....
Any pointers on how the deal with the issue will be helpful!!
Thanks

Hi Lovenish,
Goto console-> select domain> Configuration->JTA
Check timeout seconds.
2. i don't know what kind of partner link you are invoking.
check composite.xml, is there any property like retry.interval .
3. ◦SyncMaxWaitTime: The maximum time a request and response operation takes before timing out.
The maximum time a request/response operation will take before it times out. The default value is 45 seconds.

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....

BPEL process as web service data control

Hi,
I am trying to invoke a synchronous BPEL process from a jspx page. I have configured my BPEL process as web service data control object and
dropped it on my jspx as a button. But after dropping it as a button i observe that it is expecting three parameters.
I have attached the .xsd file used in the BPEL process and the screen shot of the parameter window of JDEV.
Here if you can see, i have a heirarchy of data. I have customerType which has orderType , which further has lineType.
Can somebody help me , how do i provide data to this process i.e in the parameter fields., so that it is in accordance with my .xsd of the BPEL process.
-thanks,

Oracle Spatial Web Services in ADF application

Hi,
I want to use Oracle Spatial Web Services in an ADF application (JDeveloper 11.1.2) to retrieve Longitude/Latitude after inserting/upating an address record.
Is there any sample app or documentation on how to do this?
Thank you,
Monica

I never did solve the problem. I decided to try out GeoServer for WFS and am very impressed. It was much easier to install and pretty feature-filled as well with a lot of documentation. I would definitely suggest checking it out to see if it will fit your needs.

WS-I fails with Oracle Generated Web Service

Hi
I recently used WS-I Analyzer to analyze the HTTP Analyzer logs. I get the following error:
SSBP1003
The Content-Type header is not present.
Element Location:
lineNumber=19
SSBP5101
The message either (1) did not have a "Content-Type" HTTP header field, or (2) the "Content-Type" HTTP header field had a field-value whose media type was something other than "text/xml"
Element Location:
lineNumber=19
Any ideas?

I successfully developed the oracle native web service for returning single record but the next challenge is to develop web service in order to return multiple record (like Employees data base on each department)You could return a list (multiple values/records) in XML format (using XMLType or CLOB), or CSV, or JSON, or whatever.
function get_employees (p_department_id in number) return clob
as
begin
return 'your_xml_string_here';
end get_employees;It would be up to the client (the caller of the web service) to extract the values from whatever format you decide upon, of course.

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
