OSB: Call service business, proxy non-MTOM MTOM

Hello

It is very easy to call non-MTOM MTOM active business the proxy service, but I don't know how to do it in an opposite way. I have the web service (http) with binary data in Base64 proxy in a soap body element and I would call a business (web service over http again) using MTOM format service to send binary data in binary format (and not base64 as in proxy). Is it possible to decode Base64 binary data in a kind of proxy service and send them this proxy for a service business using MTOM?

I understand the flow that you propose, but I do not know how to pass the decoded data from legend of Java to mail flow. As far as I know I can return only primitive, String and XmlObject, because nothing else can be handled in mail flow.

Yes you are right. But you can also return DataSource in the legend of java. Please http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/pojo.html

Now the solution/POC - tested on my linux machine local work

package manoj.javacallout.binary;
import java.io.BufferedReader;
import java.io.ByteArrayOutputStream.
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;

javax.activation.DataSource import;
Import javax.mail.util.ByteArrayDataSource;

import com.sun.org.apache.xml.internal.security.utils.Base64;
/**
* TODO: I use sun internal API for decoding for simplicity. You must modify this code and base64 decoding library
* Ideally should use using http://commons.apache.org/downloads/download_codec.cgi
*
* @author mneelapu
*
*/
public class Util {}
          
Public Shared DataSource decodeBase64 (DataSource ds) throws Exception {}
InputStream in = ds.getInputStream ();
BufferedReader bin is new BufferedReader (new InputStreamReader (in));.
Byte [] decodedB64 = Base64.decode (bin);
ByteArrayDataSource decodedDS = new ByteArrayDataSource(decodedB64,"binary/octet-stream");
Return (decodedDS);
}
}

Java legend at decodeBase64
Parameters
javax.activation.DataSource = [$body / *]
Result
javax.activation.DataSource = response

Now, replace the $body with the answer decoded base64 of the legend of java

Replace [content of the node] [XPath undefined]
in [body] with [$response]

Use $BEA_HOME/modules/javax.mail_1.4.jar for the compilation.
Let me know if this solves your problem.

Thank you
Maury

  • Service of Proxy Service / business does not apply by default to items

    Hi all

    I have a situation on OSB, is the case here.

    I have a Service Business based on the WSDL, and this WSDL contains some items that have the default definition = '0' (only for request schema) in the schema section.

    When an execute the SoapUI .wsdl, always the fields are filled with the default value. Yet, on OSB when I call the console for the Service of Proxy/Business test

    and run them in the following cases, without tags/value, the default value is not met.

    There is some kind of restriction or limitation on OSB on applies the default value of the schema? Or it's like a work colleague, said: "what you doing is a transformation and OSB is not done automatically."

    Thanks in advance.

    By default doesn't mean that demand for the generators must provide this value. The value is for the analyzers. When a schema-aware parser detects an optional attribute with a default value is MISSING in the inbound document, the parser must register the default value in the model of analyzed data.

    When SoapUI generates the entries to the default settings, so it's good to do. But when the test console does not generate them, it is fair to do so too, because they are optional.

    XML Schema Part 0: second edition Primer

    > Default values for elements or attributes are declared using the attribute by default, even if this attribute has a slightly different consequence in each case.

    >

    > When an attribute is declared with a default value, the value of the attribute's value as the value of the attribute in an instance document;

    > if the attribute does not appear in the instance document, the schema processor provides the attribute with a value equal to that of the default attribute.

    > Note that the default values for attributes have meaning if the attributes themselves are optional, and so there is an error to specify both a default value and

    > anything other than a value of optional for use.

    >

    > The default schema of items processor treats a little differently. When an element is declared with a default value, the value of the element is all that

    > value appears as the content of the element in the document instance; If the element appears without any content, the schema processor provides the element

    > with a value equal to that of the default attribute. However, if the element does not appear in the instance document, the schema processor does not provide

    > the item at all. In summary, the differences between elements and attributes by default can be noted:

    >

    > Default attribute values apply when attributes are missing, and default element values apply when elements are empty.

    So the question is: when you run the query from a test console and do a transformation inside the proxy, not you or do you not see the default values on the output? If you do not, the OSB Analyzer is then, mmm, not meet the standards.

  • Question about business and Service of Proxy

    Hi friends,
    I have a question about services and proxy services business IE I need to find the time it takes to call an operation on multipoint business of proxy service, how can I do in oracle service bus (OSB)? You can help quickly

    If your question is only about the performance analysis,
    try to activate the 'monitoring' on the 'operational' of the Service Proxy Service/Company tab.
    For the Proxy Services, if you activate at the level of the 'Action' you get a lot of information about each individual action in a power of attorney.

  • OSB: How to create Proxy call another Proxy

    Hi all

    I create project OSB (file management) contain some File.Proxy and I create project OSB (JavaCallOut) contain some CallOut.Proxy. Now I create project OSB (OSB integration) contain some Integration.proxy, I want to access (File.proxy, CallOut.proxy) (Integration.proxy) or how to access all the proxy from a URL.

    Thank you

    Sameh

    Sameh salvation,

    Ideally, if all your projects of OSB are under the same setup OSB project, then you can directly reference the proxy in your Department of Integration.proxy services.

    Otherwise, you can create commercial services for the file.proxy and the Callout.proxy services in your project of OSB (where your integration.proxy service is hosted) and then call these commercial services of the integration.proxy service.

    It will be useful.

    Hello

    If you need to call several Business Service and use the legend of Service actions and at the end, use action road. If he's single legend in proxy service using only course of Action.

    I'm not clear what you mean! Please develop...

    And in the Action of the road... > you can use request action replace action to replace the application payload content (Business Service).
    Replace the Action:
    Leave the empty Xpath in variable body with Expression [request payload structure] and use the content of the node replace!

  • Call service HTTPS OSB

    We have a requirement where I need to invoke a HTTPS OSB service... the system gave me 3 certificates...

    I get the error when I call the main service below...

    The invocation was an error: from the certificate chain [Security: 090477]-(servername here) was not trust origin SSL handshake failure...



    Can someone tell me how can I use the 3 certificates provided by the system while calling the business service HTTPS service...



    I created a single certificate file (AllCertificates.cer) with the content of all three certificates provided by the target system. I tried under commond assuming we need import the certificate in jdk so the runtime of osb will check with jkd certificate

    but I am still experiencing the same error... maybe I do not correctly or need me some conifguration

    Because you have chosen to use the jdk keystore as your trusted keys file, you must change the keystore parameter in the console of administration--> --> tab keystore keystore to define custom identity and Java Standard Trust.

    With the SOAP body set up using $body directly, with a payload of set up, you can use different variables... In addition, payload to configure supports NO - CPP, encoded SOAP... I have never come across a use case where I had to use the payload...

  • How to pass an xml CDATA in the string element when OSB call a webservice?

    How to pass an xml CDATA in the string element when OSB call a webservice?

    I have a business service (biz) this route to exploitation of a Web service.

    An example of this legacy Web service request:
    < soapenv:Envelope xmlns:soapenv = 'http://schemas.xmlsoap.org/soap/envelope/' xmlns: ex = "example" >
    < soapenv:Header / >
    < soapenv:Body >
    < ex: run >
    < ex: arg > <! [CDATA [< searchCustomerByDocumentNumber >
    < documentNumber > 12345678909 < / documentNumber >
    [[< / searchCustomerByDocumentNumber >]] > < / ex: arg >
    < / ex: run >
    < / soapenv:Body >
    < / soapenv:Envelope >

    type ex: arg is a string.

    How to pass this structure CDATA webservice in OSB?

    Steps to resolve this problem:
    1 create an XML schema. For example:


    elementFormDefault = "unqualified" >


              
                   
                        
                             
                             
                        
                        
                             
                        
                   
         
         
         
         

    With this XSD, XML can be generating:


    documentNumber

    2 create an XQuery query to create a ComplexType searchCustomerByDocumentNumber. For example:
    (: pragma bea: element global-element-return = "searchCustomerByDocumentNumber" location = "searchCustomerByDocumentNumber.xsd" ::))

    declare namespace xf = "http://tempuri.org/NovoSia/CreateSearchCustomerByDocumentNumber/";

    declare function xf:CreateSearchCustomerByDocumentNumber($documentNumber_as_xs:string)
    as {(searchCustomerByDocumentNumber)}

    {$documentNumber}

    };

    declare the variable $documentNumber as XS: String external;

    XF:CreateSearchCustomerByDocumentNumber ($documentNumber)

    3. in your step in proxy pipeline add to assign the created the XQuery function call from the number of the document of your payload.
    Assign to a variable (for example: called searchCustomerByDocumentNumberRequest)

    4. create an another Transformation of XQuery (XQ) to create a request to the existing Web service. For example:
    {fn - bea: serialize ($searchCustomerByDocumentNumberRequest)}

    For more information about xquery Serialize function:
    41.2.6 fn - bea: serialize()
    You can use the fn - bea: serialize() function if you need to represent an XML document as a string instead of as an XML element. For example, you can share an XML document through an EJB interface and the EJB method takes the string as an argument. The function has the following signature:

    FN - bea: serialize($input as item()) as xs: string

  • BPEL is create multiple instances of a single HTTP OSB call

    Hello

    OK guys, we found the solution. We had to update the files of PVE strategy on our SOA server Linux machine.

    Thanks to Varun Guruvugari (Support Salesforce) who responded with below the answer on another forum:

    --===========================
    There are countless reasons for uninitialized encryption error, but I'm sure that this reason is because of SSL certificates and you saw the error above for good reasons that salesforce.com ensures the safety and security.

    You will be able to integrate successfully in this instance, by deploying the latest version of the files of Extension JCE (Java Cryptography) unlimited strength jurisdiction policy-6 for JDK1.6 on the server SOA in FMW.
