WebLogic Server 6.1 Code Examples, BEA Systems, Inc.

Package examples.iiop.ejb.entity.cppclient

This directory contains a c++ client which can be used to call an entity session bean from WebLogic server. 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 configuring the WebLogic Server and deploying the entity bean. Do this first.

  • iiop.entity.server.wls

    Also, 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. For example:
    <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">
    

    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\entity\cppclient directory of your WebLogic Server installation.

    Run the Example

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

    2. Set up the environment for your client as described in Setting up your environment for building and running the examples. Make sure you have specified your Visibroker home in the iiop.properties file (wlserver6.1/samples/examples/iiop/iiop.properties) as well as include any necessary directories in your PATH.

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

      Enter the correct hostname and port for your particular configuration
