Installing and configuring KIE Server on IBM WebSphere Application Server

Procedure

1. Download IBM Installation Manager version 1.8.5 or later from the IBM Installation Manager and Packaging Utility download links page. IBM Installation Manager is required for installing IBM WebSphere.

2. Extract the downloaded archive and run the following command as the root user in the new directory:

   sudo ./install

   Copy to Clipboard Toggle word wrap

   The IBM Installation Manager opens.

3. Go to File → Preferences and click Add Repository.
4. In the Add Repository window, enter the repository URL for IBM WebSphere 9.0. You can find all the repository URLs in the Online product repositories for IBM WebSphere Application Server offerings page of the IBM Knowledge Center.
5. In your command terminal, navigate to the IBM WebSphere Application Server folder location that you specified during the installation.

6. Change to the /bin directory and run a command similar to the following example to create an IBM WebSphere profile, user name, and password. A profile defines the run time environment. The profile includes all the files that the server processes in the runtime environment and that you can change. The user is required for login.

   sudo ./manageprofiles.sh -create -profileName testprofile -profilePath /profiles/testprofile  -adminUserName websphere -adminPassword password123

7. In your command terminal, navigate to the bin directory within the profile that you created (for example, /profiles/testprofile/bin) and run the following command to start the IBM WebSphere Application Server instance:

   sudo ./startServer.sh <SERVER_NAME>

   Copy to Clipboard Toggle word wrap

   <SERVER_NAME> is the IBM WebSphere Application Server name defined in Servers → Server Types → IBM WebSphere Application Servers of the WebSphere Integrated Solutions Console.

8. Open the following URL in a web browser:

   http://<HOST>:9060/ibm/console

   Copy to Clipboard Toggle word wrap

   <HOST> is the system name or IP address of the target server.

   For example, to start the WebSphere Integrated Solutions Console for a local instance of IBM WebSphere running on your system, enter the following URL in a web browser:

   http://localhost:9060/ibm/console

Procedure

1. Declare the Red Hat Business Automation BOM in the pom.xml file:

   <dependencyManagement>
    <dependencies>
     <dependency>
      <groupId>com.redhat.ba</groupId>
      <artifactId>ba-platform-bom</artifactId>
      <version>7.7.0.redhat-00002</version>
      <type>pom</type>
      <scope>import</scope>
     </dependency>
    </dependencies>
   </dependencyManagement>
   <dependencies>
   <!-- Your dependencies -->
   </dependencies>

   Copy to Clipboard Toggle word wrap

2. Declare dependencies required for your project in the <dependencies> tag. After you import the product BOM into your project, the versions of the user-facing product dependencies are defined so you do not need to specify the <version> sub-element of these <dependency> elements. However, you must use the <dependency> element to declare dependencies which you want to use in your project.

   • For a basic Red Hat Decision Manager project, declare the following dependencies, depending on the features that you want to use:

     Embedded decision engine dependencies

     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-compiler</artifactId>
     </dependency>
     
     <!-- Dependency for persistence support. -->
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-persistence-jpa</artifactId>
     </dependency>
     
     <!-- Dependencies for decision tables, templates, and scorecards.
     For other assets, declare org.drools:business-central-models-* dependencies. -->
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-decisiontables</artifactId>
     </dependency>
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-templates</artifactId>
     </dependency>
     <dependency>
       <groupId>org.drools</groupId>
       <artifactId>drools-scorecards</artifactId>
     </dependency>
     
     <!-- Dependency for loading KJARs from a Maven repository using KieScanner. -->
     <dependency>
       <groupId>org.kie</groupId>
       <artifactId>kie-ci</artifactId>
     </dependency>

   • To use the KIE Server, declare the following dependencies:

     Client application KIE Server dependencies

     <dependency>
       <groupId>org.kie.server</groupId>
       <artifactId>kie-server-client</artifactId>
     </dependency>

     Copy to Clipboard Toggle word wrap

   • To create a remote client for Red Hat Decision Manager, declare the following dependency:

     Client dependency

     <dependency>
       <groupId>org.uberfire</groupId>
       <artifactId>uberfire-rest-client</artifactId>
     </dependency>

     Copy to Clipboard Toggle word wrap

   • When creating a JAR file that includes assets, such as rules and process definitions, specify the packaging type for your Maven project as kjar and use org.kie:kie-maven-plugin to process the kjar packaging type located under the <project> element. In the following example, ${kie.version} is the Maven library version listed in What is the mapping between Red Hat Decision Manager and the Maven library version?:

     <packaging>kjar</packaging>
     <build>
      <plugins>
       <plugin>
        <groupId>org.kie</groupId>
        <artifactId>kie-maven-plugin</artifactId>
        <version>${kie.version}</version>
        <extensions>true</extensions>
       </plugin>
      </plugins>
     </build>

     Copy to Clipboard Toggle word wrap

3. If you use a decision engine with persistence support in your project, you must declare the following hibernate dependencies in the dependencyManagement section of your pom.xml file by copying the version.org.hibernate-4ee7 property from the Red Hat Business Automation BOM file:

   Hibernate dependencies in decision engine with persistence

   <!-- hibernate dependencies -->
   <dependencyManagement>
     <dependencies>
       <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-entitymanager</artifactId>
       <version>${version.org.hibernate-4ee7}</version>
       </dependency>
   
       <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-core</artifactId>
       <version>${version.org.hibernate-4ee7}</version>
       </dependency>
     </dependencies>
   </dependencyManagement>
