10.1.3.5 - Using WSIF binding in BPEL

Hi,
I'm trying to use WSIF binding for a java web service in my bpel process. I'm following the steps given at http://www.oracle.com/technology/pub/articles/bpel_cookbook/juric.html
I used Jdev to create wsdl for my java class and enabled WSIF bindings. I copied the generated wsdl to my bpel process and used it to create a partnerlink. Now I want to generate XML facade classes using schemac compiler. I modified the BPEL build.xml to call schemac for my generated wdl. The schemac errors out with following message:
[schemac] schemac> parsing schema file 'C:\share\jdevuserhome\home5\mywork\TestApps\TestWSIF3/bpel/WsifBindingDoc.wsdl' ...
[schemac] schemac> Loaded schemas from wsdl located at C:\share\jdevuserhome\home5\mywork\TestApps\TestWSIF3/bpel/WsifBindingDoc.wsdl

[schemac] warn: The W3C datatype 'hexBinary' is not currently supported by Collaxa schemac.

Invoking a webservice using WSIF Binding

Hi All,
I have few queries regarding usage of WSIF Binding in BPEL
My understanding was it is useful for calling Java Classes from BPEL Process.
Can I use WSIF Binding for invoking the webservice ?
Or the use of WSIF Binding is limited to invoking Java classes.
If we can invoke web service , Can you please let me know how to do it?
you can mail your replies to [email protected]
Any help will be immensely appreciated..
Regards,
Bhanu

First of all thanks to Jens and clemens.
From both of your replies, i learnt that we can call webservice from BPEL process using WSIF binding .
Can you provide me a bpel sample where we're using wsif binding for invoking web service?
I have one more doubt:
"WSIF java binding means, which was used to call java classes. WSIF soap binding used to call web services"
Is my understanding correct?
Can you explain a bit on WSIF Java binding?
Regards,
Bhanu

SaxParser error while using WSIF bindings in BPEL

Hi All,
I am using WSIF bindings in BPEL to invoke a java class.
This java classs is using Jersey Client. For this I have imported relevant jersey jar files version 1.1.4.1.
My java class is getting invoked and even the jersey client jars are also recognized by my project.
But I am getiing the following SAX parser error:
*Operation failed!; nested exception is: javax.ws.rs.WebApplicationException: javax.xml.bind.JAXBException: Error creating SAXSource - with linked exception: [org.xml.sax.SAXNotSupportedException: SAX feature 'http://xml.org/sax/features/external-general-entities' not supported.]*
I found the following details when checked the logs.
JAXP feature XMLConstants.FEATURE_SECURE_PROCESSING cannot be set on a SAXParserFactory. External general entity processing is disbaled but other potential securty related features will not be enabled.
Please let me know what should be done in order to solve this issue.
Thanks in advance!!!

I am having the same problem in a non-BPEL application. I am using Oracle MDS in an application that is also using Jersey 1.1.4.1 and it blows up Jersey 1.1.4.1 in the same way.
Oracle MDS has a dependency on Oracle XDK, an XML parser (xmlparserv2.jar). xmlparserv2.jar registers Oracle's oracle.xml.jaxp.JXSAXParserFactory using the Java ServiceLoader API (by using the file META-INF/javax.xml.parsers.SAXParserFactory.
Jersey doesn't like Oracle's JXSAXParserFactory, as you can see. From what I've found so far, it seems that the Oracle SAXParserFactory is clamped down for security and Jersey will not work with it. Here is a more complete stack trace that I have:
[org.xml.sax.SAXNotSupportedException: SAX feature 'http://xml.org/sax/features/external-general-entities' not supported.]
at com.sun.jersey.core.provider.jaxb.AbstractJAXBProvider.getSAXSource(AbstractJAXBProvider.java:178)

at com.sun.jersey.core.provider.jaxb.AbstractRootElementProvider.readFrom(AbstractRootElementProvider.java:105)
Caused by: org.xml.sax.SAXNotSupportedException: SAX feature 'http://xml.org/sax/features/external-general-entities' not supported.
at oracle.xml.parser.v2.NonValidatingParser.setFeature(NonValidatingParser.java:1974)
at oracle.xml.parser.v2.SAXParser.setFeature(SAXParser.java:270)
at oracle.xml.jaxp.JXSAXParserFactory.newSAXParser(JXSAXParserFactory.java:92)
at com.sun.jersey.core.provider.jaxb.AbstractJAXBProvider.getSAXSource(AbstractJAXBProvider.java:174)
In my case, Jersey seems to ignore the system property that I set with -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
I am trying to figure out a way to satisfy the dependency that my app has on Oracle's XDK (xmlparserv2.jar) without having its SAXParserFactory take over Jersey.
I'll try to post here if I ever solve my problem because it sounds the same as yours.

Problem while using HTTP Binding in BPEL

Hello
I have a scenario where I am suppose to access a JSON based RESTful API from BPEL. I have created a HTTP binding adapter for the given endpoint.
When I test the process I am getting the following error
<part name="summary">
<summary>oracle.fabric.common.FabricInvocationException: Unable to access the following endpoint(s): REPLACE_WITH_ACTUAL_URL</summary>
</part>
<part name="detail">
<detail>Unable to access the following endpoint(s): REPLACE_WITH_ACTUAL_URL</detail>
</part>
And while I was compiling it in JDeveloper I am getting the following error
Warning(24,52): Failed to Find Binding "Get":"{http://xmlns.oracle.com/pcbpel/adapter/http/ProcessProject/GetContact/Get}Request_Response_pt" in WSDL Manager
Can anyone please help me with this?
Thanks

Thank you for the reply
I am able to contact the same endpoint from SoapUI and also the browser. As far as I know there is no proxy that is required but I will still go ahead and ask the provider.
And do you have any clue why I am getting the error in Jdev when I compile the project?
And another thing that I would like to mention is that the WSDL that the HTTP Binding adapter created is incomplete as in it does not have the <wsdl:service> tag, is that something that I should be looking out for?
This is what my WSDL (generated by HTTP Binding Adapter) looks like
<?xml version="1.0" encoding="UTF-16"?>
<wsdl:definitions
name="Get"
targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/http/ProcessProject/GetContact/Get"

WSIF Binding Error while invoking HTTP Service

Hi,
I am getting a WSIF binding error when invoking an HTTP service. I was able to successfully invoke another HTTP service on the same server. However, while invoking some of the others services, we are getting errors. The wsdl binding declaration is:
<binding name="JACADACustMaintBinding" type="tns:JACADACustMaintPortType">
<http:binding verb="POST"/>
<operation name="PostData">
<http:operation location="/custmaint.cfg"/>
<input>
<mime:mimeXml part="CustMaintInput"/>
<mime:content type="text/xml"/>
</input>
<output>
<mime:mimeXml part="CustMaintOutput"/>
<mime:content type="text/xml"/>
</output>
</operation>
</binding>

Hi,
Using the exact same wsdl i was able to get a response from the HTTP service using OSB. I created a business service targeting this wsdl. Then created a proxy service to route the xml to the business service.
I was able to successfully invoke and get response from the HTTP service without making any change to the wsdl.
Could this be a bug in BPEL PM? Should I raise an SR?

Dynamic call to a partnerlink using WSIF.

Hi,
I've already seen the "DynamicPartnerLink" sample and the "Making BPEL Processes Dynamic" cookbook.
I want to do something similar, but using WSIF. I want to be able to change binding information in runtime to be able to call Java/EJB using WSIF.
According to a Edwin (ekhodaba) post, "The only think that you can change at runtime in the address/binding information". But I don't know if this is only possible for SOAP binding.
First, I tried a similar approach to the Dynamic cookbook and example. I had a parterlink to a service with Java binding information. This worked fine. Then I changed the service name (like in the cookbook using a reference variable to change the service name, no address) to use another service with the same binding information but a different implementation Java class and I got a binding exception.
Eventually I will also wanto to do that with EJB.
Is there any way to change in runtime the WSIF binding information to call a EJB/Java class ? Any suggestions to get it? I want to have several Java classes or EJB with the same interface and be able to choose in runtime which one to call using WSIF.
Furthermore, It'd be interesting to change the Java/EJB classname, jndiName, initialContextFactory, jndiProviderURL, etc. (e.g. reading from DB or a configuration file)
Strictly speaking, this information is not needed in development time, it's only binding information so it is only useful in runtime.
I've also tried a service per Java class, but the service name can't be changed in the partnerlink in runtime, you'll get a binding error.
Thanks.

Hi, sure you will need to register your private certificate with ADF Mobile's embedded JVM. This is a security mechanism - the JVM we embed will only recognize certificates from well-know CA out of box. However, you can register your private certificate with the JVM. The steps are described in the ADF Mobile Developer Guide: http://docs.oracle.com/cd/E35521_01/doc.111230/e24475/security.htm#CDDCCDFF.
Please note that you will need to be very careful when registering the JVM - extra spaces for example will cause certificate error and it could be hard to diagnose. Please ensure all the fields matches exactly with your private certificate's fields.
Thanks,
Joe Huang

Problems calling java classe using WSIF in BPEL 10.1.3.3

Hi,
I am working on a POC for a telecom gaint in Sweden. One of their requirement is to invoke java library.
Inorder to do it, I have followed the below steps:
1. Wrote a wrapper java code to a class in this library.(Attached with this mail)
2. Using JDEV 10.1.3.3 created a wsdl file of WSIF binding type for invoking this wrapper class.(Attached with this mail.)
3. Created the required fascade classes using the SCHEMAC option in command prompt.
4. Placed all the class files including the wrapper class file in %BPELHOME%\bpel\system\classes
5. Created a BPEL process to invoke the wsif wsdl.
However while Invoking the BPEL process I am getting the error"com.collaxa.cube.ws.wsif.providers.java.WSIFOperation_Java@9ecad : Could not invoke 'authenticate'; nested exception is:
     org.collaxa.thirdparty.apache.wsif.WSIFException: No method named 'authenticate' found that match the parts specified"
Can someone tell me how to resolve this issue.
I have to do a presentation on this in 2 days.
Thanks for the help.

Error while using Java bindings in BPEL (WSIF)

Hi,
I have a requirement to invoke a java method from BPEL process using WSIF and get the response back from it.
MY java method accepts an input parameter which is object of anothe class.
When I tried to invoke the java class from BPEL, I am getting the following error:
[email protected] : Could not invoke 'getFullName'; nested exception is: org.collaxa.thirdparty.apache.wsif.WSIFException: Class 'com.services.test.Employee' is not compatible; nested exception is: java.lang.NullPointerException
Please find below the java class that I created:
package com.services.test;
import com.services.test.Employee;
import com.services.test.EmployeeFullRecord;
public class EmployeeRecord {
public EmployeeRecord() {
public static void main(String[] args) {
EmployeeRecord employeeRecord = new EmployeeRecord();
public EmployeeFullRecord getFullName(Employee emp) {
String fullName = emp.getFname() + emp.getLname();
EmployeeFullRecord emp1 = new EmployeeFullRecord();
emp1.setFullName(fullName);
return emp1;
The following is the wsdl that I created with JAva bindings:
<types>
<schema attributeFormDefault="qualified"

Hi,
I have created another such service as above and placed the class files in <oraclehome>/bpel/system/classes and invoked the java code from bPEL.
Now i am getting the following error:
com.collaxa.cube.ws.wsif.providers.java.WSIFOperation_Java@98065 : Could not invoke 'createIdentity'; nested exception is: org.collaxa.thirdparty.apache.wsif.WSIFException: Class 'com.testx.wam.services.gen.identity.CreateRequest' is not compatible; nested exception is: javax.xml.bind.UnmarshalException: unexpected element (*uri:"",* local:"createRequest"). Expected elements are <{http://services.test.com/shared/xmlschema/user/1}CreateResponse>
My question is why am I getting URL as empty when I am actually passing the URL to the service. I have highlighted the uri which is showing as empty above.
Please help me solve this issue.
Thanks in advance!!!

Unable to invoke Java WSIF Binding process

Hi,
I am using BPEL 10.1.3.1 version.
- I created Greeting.java, then from JDev generate WebService for class but did not publish or deploy as web service
- in BPEL created one partner link using same wsdl file from local file system
- put invoke activity to call this partner link
- deployed process
- copied all class file with package folder inside $ORACLE_HOME/bpel/system/classes folder
When i initiate the process i get error
Failed get wsdl service definition.
Failed to get a WSDL service that support the portType "{http://BusinessProcess/}Greeting" in WSDL definition "{http://BusinessProcess/}Greeting".
Please verify that WSDL portType "{http://BusinessProcess/}Greeting" is supported by a service in WSDL file.
Please help.

Hi Jack
Does your WSDL have the "binding" and "service" section? I do not use JDev or anything else to create the WSDL for me, I create it by hand so I don´t know how to help you in JDev, but it seens that JDev does not generate this sections and you must set then in order to use WSIF Bindings to Java or EJB.

BPEL TO BPEL using WSIF

Can I call One BPEL from another using WSIF?
Currently when I looks at the BPEL WSDL it has SOAP binding. How can I change the BPEL's WSDL to expose WSIF biniding.
Also will the WSIF binding work if both BPELs are in different container.
Thanks for your help
- Piyush

I don't think BPEL exposes it self as WSIF. You can do it via optSoapShortcut property process or domain level. If they are in same container/same jvm then it will be native.

How to use a bind variable in an IN clause

I am trying to use a bind variable in an IN clause where the column is a varchar2 type. Something like:
select *
from test
where test_column in (:bindVariable)I have tried assigning the bind variable comma separated strings (eg. test,test,test) and comma separated strings with quotes (eg. 'test','test','test'). Neither of these work. Does anyone know the correct way to do this?
Thanks in advance.

How to use a bind variable in a table-validated flexfield

Hi,
I want to prepare a table-validated descriptive flexfield, which uses as source a select statement.
So, in the form "Validation table information" I use as table name the statement:
(SELECT my_procedure('test_value') FROM DUAL)
Up to here it works fine.
But instead of 'test_value' I want to use the value of a field in the form or a value of another flex (using $FLEX$ bind variables).
Please advice if it is possible to perform this in "table name" statement. I use it in "where/order by" clauses and it works fine.
Thank you.

Hi,
I have posted in the place where you did advise,

Please, can I continue in this place with this question?
