JAX-WS webservice client basic authentication

JAX-WS webservice client basic authentication:

Sometimes we may need to create a webservice client for a JAX-WS webservice that require the basic authentication.

This post will explain the how to pass the username/password when invoking the basic authentication enabled web services from the client.

Java client with basic authentication details:

import java.util.*;
import javax.xml.ws.*;
import weblogic.wsee.security.unt.ClientUNTCredentialProvider;
import weblogic.xml.crypto.wss.WSSecurityContext;
import weblogic.xml.crypto.wss.provider.CredentialProvider;

public class DataObjectOperationsByNameClient
{
  @WebServiceRef
  private static DataObjectOperationsByName_Service dataObjectOperationsByName_Service;
  public static void main(String [] args)
  {
    dataObjectOperationsByName_Service = new DataObjectOperationsByName_Service();
    DataObjectOperationsByName dataObjectOperationsByName = dataObjectOperationsByName_Service.getDataObjectOperationsByName();
    String input="<DataObject Name=\"BAMWebservice\" Path=\"/Albin\">\n" + "<Contents>\n" + "<Row>\n" + "<Column Name=\"Field1\" Value=\"Albin\" />\n" +
    "<Column Name=\"Field2\" Value=\"I.T\" />\n" +"<column Name=\"Field3\" Value=\"TR\" />\n" +"</Row>\n" + "</Contents>\n" + "</DataObject>\n";   
      String USERNAME = "weblogic";
      String PASSWORD = "welcome1";
        try {
            BindingProvider bindingProvider = (BindingProvider) dataObjectOperationsByName;
            Map<String,Object> rc = (Map<String,Object>)bindingProvider.getRequestContext();
            List<CredentialProvider> credProviders = new ArrayList<CredentialProvider>();
            credProviders.add(new ClientUNTCredentialProvider(USERNAME .getBytes(),PASSWORD .getBytes()));
            rc.put(WSSecurityContext.CREDENTIAL_PROVIDER_LIST, credProviders);
            rc.put(BindingProvider.USERNAME_PROPERTY, USERNAME);
            rc.put(BindingProvider.PASSWORD_PROPERTY, PASSWORD);;
            dataObjectOperationsByName.insert(input);
        } catch (BAMWebServiceException e) { e.printStackTrace();      }

Building a Simple Oracle ADF page using Oracle BAM Data Control

Building a Simple Oracle ADF page using Oracle BAM Data Control

This blog will explain how to Build a Simple Oracle ADF page using Oracle BAM Data Control

The Oracle BAM reports can be built through BAM Active Studio or through BAM data control in Oracle ADF page.

In this blog I will be explaining about the steps required to build a simple ADF page using BAM data control.

Creating the BAM Connection:

• Open the JDeveloper
• Create new BAM Connection

• Enter the BAM Server details as shown below. 

• Click on Finish and Test the connection
• Create the data object in BAM through Architect view (I am using the existing data object Employee)

Runtime Exception in Oracle ADF application with Oracle BAM Data Control - Failed handling event FirstGetOnDataProvider on QueryConfigured

Runtime Exception in Oracle ADF application with Oracle BAM Data Control - Failed handling event FirstGetOnDataProvider on QueryConfigured

We may receive the following exception while running the Oracle ADF application with Oracle BAM Data Control configured into that.

The issue is because of the BAM connection details are not configured in the EM console after the deployment of the application.

If we are deploying the application to the stand alone server, the Oracle BAM connection must be re-created in Oracle Fusion Middleware Control Console after the deployment of the application.

Also application must be deployed using MDS enabled otherwise the connection details will not be persisted.

Steps to resolve this issue:

Enable the MDS for the Application:

• Right click on the project and Select Project Properties.

The issue is the oracle.adf.library.webapp.ResourceServlet class is missing in the class path.This issue can be resolved by deploying the application as EAR file instead of deploying the project as WAR file.

Steps to resolve the issue:

• Right click on the application and select Application properties

• Select Deployment and click on New
