Oracle SOA Suite Composite Deployment - Global Type declaration/definition of name *are duplicated - Part2

We were receiving the following exception while trying to invoke a composite(A) from other composite(B) in Oracle SOA Suite.

Error(284): part "payload" of variable "SFDCIN" is defined as XML element "{http://trm.com:I100:OrderProcessing:orderToQuote_Recieve}MT_BackfillStatus" whose definition cannot be resolved because "Global Type declaration/definition of name '{http://trm.com:I100:OrderProcessing:orderToQuote_Recieve}DT_BackfillStatus' are duplicated at the following locations: http://localhost:8000/soa-infra/services/CRMSYNC/SFDCOMQT_EventManager/xsd/SAP.MSG.EAI_610_OLIStatus_Quote.xsd [line#: 4] http://localhost:8000/soa-infra/services/CRMSYNC/SFDCOMQT_EventManager/sfdcomqt_eventmanager_client_ep?XSD=xsd/SAP.MSG.EAI_610_OLIStatus_Quote.xsd [line#: 5] There are at least two of them looking different: http://localhost:8000/soa-infra/services/CRMSYNC/SFDCOMQT_EventManager/xsd/SAP.MSG.EAI_610_OLIStatus_Quote.xsd [difference starting at line#:6] http://localhost:8000/soa-infra/services/CRMSYNC/SFDCOMQT_EventManager/sfdcomqt_eventmanager_client_ep?XSD=xsd/SAP.MSG.EAI_610_OLIStatus_Quote.xsd [difference starting at line#:7] ".

But the deployment of the composite(A) is success and we were able to test the composite(A) successfully from SOAP UI but while trying to invoke from other composite(B), the deployment of the invoking composite(B) failed with the above exception.

The both the differences pointing to the same xsd in the same component, one is design time xsd and another one is run time xsd.

While comparing, we were able to see some small differences between these two xsd's but unfortunately we could not able to correct it because both are pointing to the same xsd.

After a long struggle i was able to find out the root cause, the actual root cause is the annotations defined in the xsd.

The issue is due to  missing ADF web Run-time libraries in the war file.This can be resolved by adding the ADF web Runtime libraries into the war file.

Steps to resolve the issue

If you are deploying through JDeveloper then follow the below steps.

Add the ADF Web Runtime to the project libraries.

Getting the Audit Detail of a BPEL instance in JAVA - Oracle SOA Suite

In Oracle SOA Suite 11g and Oracle SOA Suite 12c,the audit trail of the BPEL is stored in the table AUDIT_TRAIL.If the size of the payload crossed the threshold size configured in the EM console then the details are stored in the AUDIT_DETAILS table.

Recovering the composites to JDeveloper from MDS - Oracle SOA Suite

Sometimes there is a possibility the latest code changes of the deployed composite in JDeveloper might have lost in other hand some cases we will not be having the implementation code for the deployed composites.

These scenarios the Oracle SOA Suite composite artifacts can be exported from MDS through em console and the same can be converted to design time artifact in JDeveloper.

This post will explain the steps to recover the composite to JDeveloper from MDS.

Steps to recover the composite from MDS

Login to Em console, right click on the particular composite and click on Export

Not able to save the projects into the JWS file(Application) in JDeveloper

Sometimes we may receive the following exception when trying to deploy a web application from JDeveloper to weblogic server.

Wildcard SSL HostnameVerifier in Weblogic Server

Before WLS release 10.3.5, weblogic  servers's hostname verification code did not supports the wildcard certificate by default we have to create a custom hostname verification code to handle this scenario but from WLS release 10.3.5, weblogic servers  hostname verification code  by default supports the wildcard certificates.

Wildcard SSL Certificates work the same way as a regular SSL Certificate, allowing you to secure the connection between the client and server(www.abc.com) but a single Wildcard SSL Certificate covers any and all of the sub-domains of the main domain(*.abc.com)

Configuring Wildcard SSL HostnameVerifier:

• Launch WLS console
• Click on Environment -> Servers and click on the server
• Then go to SSL tab
• Lock & Edit
• Scroll down and expand advanced section
• Change Hostname verification entry to Custom Hostname Verifier
• Enter Below in Custom Hostname verifier "weblogic.security.utils.SSLWLSWildcardHostnameVerifier"

• Make sure the option Use JSSE SSL is selected.

• Restart the weblogic server.

SOA-INFRA app is not starting up - Oracle SOA Suite 11g:

When we restarted the soa server, the soa server came up properly except the SOA-INFRA app.
The status of the SOA-INFRA app in weblogic console is failed and also the SOA node in the em console is not displayed.



We could not able to find any particular error from log files including diagnostic log except schema mismatch error with some of the composites.It  seems due to some reason the status of the soa-infra application is failed and the server is restarted without fixing the actual issue then even after fixing the issue and restarting the server the soa-infra app is not Active.

We have tried deleting the following folders from $DOMAIN_HOME/servers/AdminServer
data
temp 
cache 

Unfortunately even after deleting the above folders the SOA-INFRA app did not come up. 

Tried starting the SOA-INFRA app manually from weblogic console, this time the SOA-INFRA app came up and we could able to see the SOA in em console.

Polling the Message from WebSphere MQ using MQ Transport in OSB

OSB MQ transport help us to post/receive message from the WebSphere MQ. The MQ transport can be configured to poll the queue for the new messages.


This blog explains how to configure the OSB Proxy Service to poll the Queue for new messages.

Steps to configure the OSB Proxy Service to poll the Queue for new messages

Create a OSB Project and Create a Resource of  type MQ Connection.

Remote Java Client to Post the Message to IBM MQ

The below java code will help us to post the message to remote IBM MQ.

package mqclient;
import com.ibm.mq.jms.*;
import javax.jms.*;

public class MQJavaClient {
 
    public static void main(String[] args)
     {
      try {
       MQQueueConnectionFactory cf = new MQQueueConnectionFactory();
       cf.setHostName("10.130.134.178");        
       cf.setPort(2022);

Initiating an OSB Service with Email

Email transport will help us to send/receive emails in OSB. Some cases we may required to initiate the external service based on the email in the user inbox.


The Proxy service polls the Mail Inbox for the new messages and invokes the Business service whenever there is a new message in the Inbox.The polling interval can be specified in the Proxy Service configuration.Here i will explain about invoking the service with the XML message received from the email body.

Invoking the service with the XML message received from the email body

Create a XSD message structure that will be used by Proxy Service to receive the message

<?xml version="1.0" encoding="UTF-8"?>
<schema attributeFormDefault="unqualified"
elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/JEJBSample/EmployeeDetailService/EmployeeDetailService"
xmlns="http://www.w3.org/2001/XMLSchema">
<element name="EmployeeRequest">
<complexType>
<sequence>
<element name="empNo" type="string"/>
</sequence>
</complexType>
</element>
</schema>

Create a OSB project and create a Business service that needs to be invoked based on the Email content - Here i am invoking a sample BPEL service with the same XSD structure as input.

Create a Service Account with Static username/password of email user.

Exposing a OSB Proxy Service as EJB through JEJB transport

The JEJB transport lets you pass Plain Old Java Objects (POJOs) through Oracle Service Bus.To a J2EE client, a JEJB proxy service looks like a stateless session bean. A JEJB proxy service, on receiving the method arguments, passes their XML representation in the pipeline $body variable. POJO arguments are represented as the XML fragment. This XML fragment contains the location of the actual POJO stored in the object repository within the pipeline.

For deployment, Oracle Service Bus automatically packages JEJB proxy services as enterprise archives (EARs) and deploys to weblogic server(OSB Server).


JEJB transport uses the Java Interface to expose as EJB.

Here i will explain exposing the proxy service as EJB and invoking the same through java client by passing/receiving  the java objects and invoking the business service by passing/receiving the XML(Java utility methods will be used to convert Java to XML and XML to Java).The BPEL service invoked will receive the empno and and return back the employee details.

Steps to expose the proxy service as EJB

Create a Java interface that will receive/return the Employee object .

package jejbsample;
public interface EmployeeDetails {
 
    Employee getEmployeeDetails(Employee emp);
}

Steps to enable message tracking in OSB

Open project in OSB console and also create a session

ORABPEL-05250 Error - JDeveloper Part1

I faced a strange ORABPEL-05250 issue while deploying the composite to Oracle SOA Suite Server through JDeveloper.

The composite was successfully build in JDeveloper but during deployment to the server received the following exception.

[03:59:18 PM] Sending internal deployment descriptor

ORABPEL-05250 exception can occur for number of reasons . After a long struggle( tried removing the partner links one by one) received the actual error

There was an error deploying the composite on AdminServer: Error occurred during deployment of component: SFDCOT_Invoker to service engine: implementation.bpel, for composite: SFDCOT_Invoker: ORABPEL-09705

Could not initialize variable.
An error occurs while initializing BPEL variable inputVariable; the schema processor cannot find the element {http://xmlns.oracle.com/pcbpel/adapter/db/top/SFDCOT_POLLING_V}SfdcotPollingVCollection in the following schemas: oracle.fabric.common.wsdl.SchemaManager@7eb126f4.
The XSD element on which the variable was based was not properly defined in XSD or the WSDL.

Ensure that the element named in the error message is valid in the XSD or the WSDL.

The issue is due to schema name in the wsdl file is wrongly specified(wrong case) even though the schema name was wrongly specified in wsdl the composite was able compile and build successfully in JDeveloper installed in windows but failed while deploying to the server running in UNIX, this is due to case sensitive nature of file names in UNIX OS


After correcting this issue the composite got deployed successfully.

The WSDL is not semantically valid: The element or type specified for part'payload' in message cannot be found in any schemas referenced by this wsdl - Oracle OSB

While creating the WSDL resource in OSB with inline schema refereed to create the message types we may receive the following exception even though the wsdl is valid

An error occurred creating the resource:

Common customization file to deploy OSB services to different environments

The customization file can be used to customize the OSB services.
This post will explain how to use the common customization file to customize the OSB services.

Steps to use common customization file to customize the OSB services

1. Create a environment specific property files with the end point details ex Dev_build.properties

# SFDC Details
sfdc.protocol=http
sfdc.host=10.23.23.11

siebel.protocol=http
siebel.host=10.23.23.12


2. Common customization file

To customize the end point details for the business service, we have to change the Service URI and Service URI Table.
we have to tokenize the endpoint details so that the values can be replaced from the environment specific file.

For each new OSB service generate the customization file and copy the required sections(mainly <cus:envValueAssignments> of Service URI and Service URI table <cus:envValueAssignments>) to the common customization file.

<?xml version="1.0" encoding="UTF-8"?>

Customization File:

Customization file will help us to modify the environment specific values for a OSB project.
The previous post can be referred for more details on customization file.

Modify the  environment specific values in the customization file.

Running the Script:

Login to the server and copy the wlst script and the Customization file to some location.
Execute the below two commands

CLASSPATH=$CLASSPATH:$OSBHOME/modules/com.bea.common.configfwk_1.5.0.0.jar:$OSBHOME/lib/sb-kernel-api.jar:$OSBHOME/lib/sb-kernel-impl.jar;export CLASSPATH

wlst.sh /home/eaiapp/Albin/OSBCustomization.wlst

Before executing the first command change the com.bea.common.configfwk_1.5.0.0.jar file version according to your environment.

After successful execution verify the service from OSB Console

Removing the default rowselector column from DOJO Enhanced Grid:

Make sure the value for rowSelector is set as 0px or remove rowSelector property from the grid definition.

var grid = new dojox.grid.EnhancedGrid({
        id : gridObjectName,
        structure : layout,
        rowSelector : '0px',
        sortFields: [{attribute: defaultsort, ascending: true}],
        noDataMessage:"<span class=\"dojoxGridNoData\">No Matching Rows Found!!</span>",
        plugins : {
            indirectSelection:selection,
            pagination : {
                pageSizes : [ "25", "50", "100" ],
                description : true,
                sizeSwitch : true,
                pageStepper : true,
                gotoButton : true,
                /* page step to be displayed */
                maxPageStep : 4,
                /* position of the pagination bar */
                position : "bottom"
            }
        }
    }

Programmatically Uncheck/Check DOJO Checkboxs

The below lines of code will help us to check /uncheck set of dojo checkboxes from javascript.

dojo.forEach (dojo.query("input[type=checkbox]"), function(item){
var widget = dijit.getEnclosingWidget(item);
alert(widget)
widget.set('checked', false);
})

We can change the dojo.query parameter accordingly to fetch the checkboxes.

Testing the Spring Service layer through JUnit

Steps to enable Junit test for spring service layer

This post will explains the steps required to test the spring service layer through JUnit without deploying to the server.

Right Click on the service class for which the test class needs to be created and click on New and select JUnit Test Case


Click on Next and provide the Test Class Name and the package to which the test class has to be created.


Click on Next and select the methods for which the test methods needs to be created and click on finish.

Fetch Type vs Fetch Mode in Hibernate

Fetch type (lazy/eager) tells when Hibernate fetches the association, whether in advance when it fetches the entity (eager), or whether it waits for the code to ask for the association (lazy).

Fetch mode (select/join) refers to how Hibernate will fetch the association, i.e. does it use an extra SELECT statement, or does it use a join.

Some combinations of these make no sense, e.g. lazy+join. If you use lazy fetching, then SELECT fetch mode is the only one that you can do.If you use eager fetch, then you can choose to use either fetch mode.

Creating Validation TextArea in DOJO:

Sometimes we may need to do the validation of the data entered in TextArea but unfortunately the default TextArea provided by DOJO will not support the validation .

We can create a custom component extending both dijit.form.ValidationTextBox and dijit.form.SimpleTextarea, this will provide the functionality of both the ValidationTextBox and
SimpleTextarea.

dojo.declare(
            "ValidationTextarea",
            [dijit.form.ValidationTextBox,dijit.form.SimpleTextarea],
            {
                  postCreate: function() {
                    this.inherited(arguments);
                },
                validate: function() {
                    if (arguments.length==0) {
                    return this.validate(false);
                    }
                    return this.inherited(arguments);
                    },           
                onFocus: function() {
                    if (!this.isValid()) {
                        this.displayMessage(this.getErrorMessage());
                    }
                },
               onBlur: function() {
                    this.validate(false);
                }
             }
        );

We have to add the dojo require for ValidationTextarea  -  dojo.provide("ValidationTextarea");

Using the ValidationTextarea in jsp page:

<textarea id="clntlocn" name="clntlocn" data-dojo-type="ValidationTextarea" required="true" missingMessage="Enter the Client Location Name" rows="2" cols="20"" maxLength="50" style="resize:none"></textarea>

Now we can include all the validations applicable for dijit.form.ValidationTextBox to
ValidationTextarea.
