configuring the http proxy in weblogic

To configure the proxy in weblogic configure the below properties in setDomainEnv:

-DproxySet=true
-Dweblogic.webservice.transport.http.proxy.host=proxy
-Dweblogic.webservice.transport.http.proxy.port=80
-Dweblogic.webservice.transport.https.proxy.host=proxy
-Dweblogic.webservice.transport.https.proxy.port=80
-Dhttp.proxyHost=proxy
-Dhttp.proxyPort=80
-Dhttp.nonProxyHosts="172.16.40.84|172.16.40.63"
-Dhttps.proxyHost=proxy
-Dhttps.proxyPort=80
-Dhttps.nonProxyHosts="172.16.40.84|172.16.40.63"

If the proxy is accepting username/password
Or if you face the below issue,
weblogic.net.http.HttpUnauthorizedException: Auth scheme Negotiate is not supported!
then you may need to write the custom authenticator for calling the service behind proxy.

Please find the below example for custom proxy authenticator:

Write the class that extends java.net.Authenticator.
***
import java.net.Authenticator;
import java.net.PasswordAuthentication;

public class ProxyAuthenticator extends Authenticator {
    private String username;
    private String password;
    public ProxyAuthenticator(String username, String password){
        this.username = username;
        this.password = password;
    }
    public PasswordAuthentication getPasswordAuthentication () {
        return new PasswordAuthentication (username, password.toCharArray());
    }

}
***

From your code, before calling the service over the http set the above authenticator.

//I set the proxy again for safer side
System.setProperty("http.proxyHost", "proxy");            
System.setProperty("http.proxyPort", "80");
System.setProperty("https.proxyHost", "proxy");            
System.setProperty("https.proxyPort", "80");

Authenticator.setDefault (new ProxyAuthenticator("username","password"));

JAVA embedding in Oracle SOA 12c

Image
In this post we will explore how to EMBED Java or call Java API from Oracle SOA BPEL process. In order to demonstrated this, I have created a simple JAVA project with 3 classes. 1.        Account.java -> This class represent Account DTO       2.       Party.java -> This class represent a party (customer) DTO       3.       GetNumber.java -> This class contains the method that takes Party DTO as input and apply some business logic and return party’s AccountDTO in response. public Account getNumber(Party party) The above classes are created to simulate the calling of actual business logic API’s. Account.java Party.java GetNumber.java public class Account {     public Account() {         super();     }     String account;     public v...

API Design First approach: Implementing quick mock API's using swagger hub and postman

Image
Consider a scenario, where you as a API developer been ask to to implement the API's for a new mobile/web application team. The requirement is to implement a application to allow users to manage orders.         Mobile APP -> API infra->Backend enterprise system While implement a full working API might take days, you also do not want the application team to wait till the API's are ready. Thus, in most case we end up implementing the mock API's with sample scenarios. In this post, we will define an API using swagger openapi 3.0 yaml specification in swaggerhub. We will then use the definition to implement mock API's in postman. Even though postman provide option to define the API's, i liked swagger hub much better, it allow you to view your API on right side.  For this post I implemented API definition in swagger, please find the below link. https://app.swaggerhub.com/apis-docs/lopesrohan1988/ordermanagement/1.0.0 API Definition can be found at below link: h...

Passing/Receiving HTTP header in SOA BPEL

Image
In this example we will explore how to pass or receive the parameters from HTTP header. We will explore below two scenarios, To receive the HTTP header from SOAP request. To pass the HTTP header while calling soap service. SOA version used: 12.1.3c To receive the HTTP header from SOAP request: First we need to add the property “oracle.webservices.http.headers” under binding.ws in Service element in composite.xml. This property contains the comma separated parameters that we are expecting in request. Example,  ENV,VERSION. <binding.ws port="http://xmlns.oracle.com/SOA_Learning/HTTPHeader/HTTPHeaderTest#wsdl.endpoint(httpheadertest_client_ep/HTTPHeaderTest_pt)">          <property name="oracle.webservices.http.headers">ENV,VERSION</property> </binding.ws> Now in BPEL source under receive activity, we need add <fromProperties> element which will copy the parameters from HTTP heade...
