Interface JboContext

All Superinterfaces:

javax.naming.Context

All Known Implementing Classes:

ColoInitialContext, InitialContextImpl, InitialContextImpl, JboInitialContext, WLEJBInitialContext

public interface JboContext

extends javax.naming.Context

Defines additional properties (or environment variables) for the initial context. The following table describes the properties, their possible values, and the platforms for which they are required.

Context Property	Description	Required on Platforms
DEPLOY_PLATFORM	Platform to which an Application Module is deployed. One of PLATFORM_LOCAL, PLATFORM_VB, PLATFORM_EJB, or PLATFORM_ORACLE8I.	ALL
INITIAL_CONTEXT_FACTORY	Must be JBO_CONTEXT_FACTORY.	ALL
HOST_NAME	Host on which the Application Module server is deployed. Required on Visibroker for USE_BIND mode only.	Oracle8i, Visibroker
CONNECTION_PORT	Port number where the ORB listens for IIOP requests	Oracle8i
CONNECTION_MODE	Specifies how to connect to Application Module server. Clients can connect to an Application Module server started on a remote host (USE_BIND mode), find the server using the Visibroker naming service (REMOTE mode), or load the server in the client's VM (COLOCATED mode).	Visibroker
ORACLE_SID	Oracle8i service ID to identify the ORB service.	Oracle8i
APPLICATION_PATH	JNDI path under which an Application Module is registered. Full path under which an Application Module is published.	Oracle8i
USE_APPLET	Must be used whenever the client is an applet.	Visibroker, Oracle8i
SECURITY_PRINCIPAL	User name. Required for connecting to an Application Module deployed as CORBA server or an EJB session bean.	Oracle8i
SECURITY_CREDENTIALS	Password. Required for connecting to an Application Module deployed as CORBA server or an EJB session bean.	Oracle8i

Using the Context Properties

You first create a hashtable to store the properties:

 static Hashtable env = new Hashtable(10);
 

Your code must also include a definition of the Application Module home:

 static ApplicationModuleHome mHome ;
 

You must include code to connect to the database. Then set the properties for deploying.

Setting Properties for Deploying Locally

The following code snippet illustrates how to set the properties to run an Application Module deployed locally.

  // Component running locally
     {
     public static void setLocalEnv()  {
     env.put(JboContext.INITIAL_CONTEXT_FACTORY,
                        JboContext.JBO_CONTEXT_FACTORY);
     env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
     }
   }
 

Setting Properties for Deploying on Oracle8i as a CORBA Server Object

The following code snippet illustrates how to set the properties for loading an Application Module deployed on Oracle8i as a CORBA object.

 // Component deployed to Oracle8i CORBA Server.
 // Set up the 8i environment
    public static void set8iEnv()   {
    env.put(JboContext.INITIAL_CONTEXT_FACTORY,
                      JboContext.JBO_CONTEXT_FACTORY);
    env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_ORACLE8I);
    env.put(JboContext.SECURITY_PRINCIPAL, "scott");
    env.put(JboContext.SECURITY_CREDENTIALS, "tiger");
    env.put(JboContext.HOST_NAME, "localhost");
    env.put(JboContext.CONNECTION_PORT, "2481");
    env.put(JboContext.ORACLE_SID, "ORA815");
    env.put(JboContext.APPLICATION_PATH, "test");
  }
 

Setting the Environment for Deploying on Oracle8i as an EJB

The following code snippet illustrates how to use the properties to set the environment for loading an Application Module deployed on Oracle8i as an EJB.

  // Component deployed to Oracle8i as EJB.
  // Set up the 8i environment
     public static void set8iEnv()  {
     env.put(JboContext.INITIAL_CONTEXT_FACTORY,
                       JboContext.JBO_CONTEXT_FACTORY);
     env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_EJB);
     env.put(JboContext.SECURITY_PRINCIPAL, "scott");
     env.put(JboContext.SECURITY_CREDENTIALS, "tiger");
     env.put(JboContext.HOST_NAME, "localhost");
     env.put(JboContext.CONNECTION_PORT, "2481");
     env.put(JboContext.ORACLE_SID, "ORA815");
     env.put(JboContext.APPLICATION_PATH, "test");
  }
 

Setting the Environment for Visibroker Servers

For examples of setting the environment for Visibroker Servers, see ConnectionModeConstants

Setting the Initial Context and Loading the Application Module

The following code snippet illustrates creating an initial context for the environment and creating the Application Module d2e.D2eModule in the database. This Application Module was created at design time.

 // Load the Application Module
    ApplicationModule appMod = null;
      try
        {
          Context ic = new InitialContext(env);
          String theAMDefname="d2e_D2eModule";
          ApplicationModuleHome home =
                              (ApplicationModuleHome)ic.lookup(theAMDefName);
          ApplicationModule appMod = home.create();
          appMod.getTransaction().connect("jdbc:oracle:thin:scott/tiger@pc3:1521:ORCL");
          return appMod;
        }
        catch(Exception e) {
      e.printStackTrace();
   }
