WebLogic Server 6.1 Code Examples, BEA Systems, Inc.

Package examples.iiop.ejb.stateless.cppclient

This directory contains a C++ CORBA client which can be used to call a stateless session bean from WebLogic and to additionally make an outbound call to a Tuxedo server. It also demonstrates using complex java data types with C++. You must have Visibroker 4.1 installed on your machine in order to get the example running. You set the location of visibroker by modifying the iiop.properties located in the WL_HOME/samples/examples/iiop folder (for example, it would likely be set to INPRISE_HOME=c:/Inprise/vbroker). You also need a C++ compiler; this example used Microsoft Visual C++. Make sure that your PATH is set so that the compiler can be run.

Before you run the client applications in this directory, be sure to build the full example. This includes building the WebLogic Server and, if you wish to run an outbound call to Tuxedo, the Tuxedo Server (iiop/stateless/server/tux) as well.

    Be sure to also take a look at the C++ client code.

    Visibroker

    There are many bugs in Visibroker that make configuring your files and environment correctly a difficult process (Note how we must force GIOP version below). This example demonstrates using Visibroker with an EJB, but it also simultaneously demonstrates how difficult this process can be. It is not recommended to utilize this sort of implementation in production systems.

    Configure WebLogic

    Due to a Visibroker bug in GIOP 1.2 you must force Visibroker to use GIOP 1.1. You can do this by adding the DefaultGIOPMinorVersion element to your Server MBean in the config.xml contained in the WL_HOME/config/examples directory (also, because we cannot currently force GIOP on Tuxedo, this example only works when calling WebLogic--though you can still make an outbound call from WebLogic to Tuxedo). Below is an example of using the DefaultGIOPMinorVersion attribute:
    <Server AcceptBacklog="50" AdministrationPort="0" ClusterWeight="1"
            ConsoleInputEnabled="false" DGCIdlePeriodsUntilTimeout="2"
            DefaultGIOPMinorVersion="1" DefaultProtocol="t3"
            DefaultSecureProtocol="t3s" HttpdEnabled="true"
            JavaCompiler="C:\BEA\jdk131/bin/javac" ListenPort="7001"
            Name="examplesServer" NativeIOEnabled="true"
            RootDirectory="C:\BEA\wlserver6.1"
            SocketReaderTimeoutMaxMillis="10"
            TransactionLogFilePrefix="config/examples/logs/"
            TunnelingClientPingSecs="45" TunnelingClientTimeoutSecs="40"
            XMLEntityCache="XMLCacheMBean" XMLRegistry="examplesXMLRegistry"><Server DefaultGIOPMinorVersion="1">
    

    Build the example

    1. Set up your development shell as described in Setting up your environment.

    2. Execute the build script provided for this example in the samples\examples\iiop\ejb\stateless\cppclient directory of your WebLogic Server installation.

    Run the Example

    1. Make sure you have started the WebLogic Server as per the directions for WL_HOME/samples/examples/iiop/ejb/stateless/server/wls.

    2. Open a separate command-line window in which you will run the client.

    3. Set up the environment for your client as described in Setting up your environment for building and running the examples.

    4. Run the client by executing the Client.exe:
      
       Client -ORBInitRef NameService=iioploc://ip_address:7001/NameService 
      

      Enter the correct ip address and port for your particular configuration

    5. To run the client and make an outbound call to Tuxedo make sure you have built and properly configured the included components necessary for both the Tuxedo server and WebLogic (iiop/samples/examples/ejb/stateless/server/wls and iiop/samples/examples/ejb/stateless/server/tux). Then run the client application with the following command:
      
       Client -ORBInitRef NameService=iioploc://localhost:7001/NameService true
      

      Enter the correct host and port for your particular configuration
