Changes In This Release

Oracle Help 11.1.2.1.0 is a new release that contains mostly bug fixes, except for the following.

  • This release contains bug fixes and an enhancement to the search functionality. You can now include a * character in a search term. For example, searching for add* will match all words that begin with "add".

Dependency Information

Sun Microsystems Java SE 6.0 or higher is required to use OHW 11.1.2.1.0 . Java SE 6.0 is recommended.

Using OHW with your ADF Application

Approach 1: OHW (ohw-rcf-demo.ear) deployed as a Standalone Application and integrated with your ADF application

  • We recommend that you build you ADF application and then use the helpTopicId attribute to link your ADF application to OHW-RC. However, we recommend that you deploy OHW-RC separately from the ADF application. This keeps the setup and configuration cleaner and easier to debug and support. For example, by deploying OHW-RC separately, you can fine-tune the web.xml file for OHW-RC and your ADF Application separately to ensure each is optimized for its specific use.

Deploying OHW-RC Demos in WebLogic (WLS)

  • ohw-rcf-demo-thin.ear: Meant to be deployed through and instance of WLS that already had the adf-faces and trinidad runtime jars installed (the shared library adf.oracle.domain.webapp).
  • ohw-rcf-demo-thick.ear: Comes with local copies of the adf-faces and trindad runtime jars, and thus can be deployed through an instance of WLS that isn't configured to use adf.oracle.domain.webapp shared library.

Option 1: Deploying ohw-rcf-demo-thin.ear to a standalone WLS

  1. Start the WebLogic DefaultDomain
  2. Access http://localhost:7101/console (The WebLogic Server's administration console)
  3. Login using weblogic/weblogic1
  4. Click on the 'Deployments' Link
  5. Ensure that you have ADF installed
  6. Click the 'Install' button
  7. Navigate and select WebLogic ready application EAR file and click on the 'Next' button
  8. Select 'Install this deployment as an application' and click on 'Next' and 'Finish' and 'Save' button
  9. OHW-RCF is accessible by accessing http://localhost:7101/help-ohw-rcf-context-root/ohguide (if you haven't modified the ohw-rcf-demo-thin.ear's META-INF/application.xml, then the context root is "ohw-rcf-demo", which means http://localhost:7101/ohw-rcf-demo/ohguide will start the application)

Option2: Running the ohw-rcf-demo-thin.ear from JDeveloper

  1. Start JDeveloper 11g
  2. Select File -> New -> Application from EAR File
  3. Select the ohw-rcf-demo-thin.ear file and click 'Finish'
  4. Right-click the ohw-rcf-demo-thin project and select Deploy -> to IntegratedWLSConnection. Access the demo via http://localhost:7101/ohw-rcf-demo/ohguide (If the prior link does not work try http://localhost:7101/ohw-rcf-demo-thin/ohguide)

Approach 2: OHW as part of a Web Application

  • If for some reason you cannot deploy OHW-RC separately, you can add OHW-RC files directly to your ADF Application and deploy everything together. We do not recommend this approach as it tends to make things much arder to debug and support. For example, if you deploy OHW-RC together with your ADF App, both will share the same web.xml file, which will not allow you to fine-tune the OHW-RC application separately from the ADF Application as is often desirable.
  • There are serveral files needed to run OHW RC correctly:
    • ohw-rcf.jar
    • ohw-share.jar
    • help-share.jar
    • ohw-rcf-webapp.zip

Understanding OHW-RC Deployment as Part of Web Application

Once help authors are done with the help contents, then the OHW administrator will need to modify the web configuration to deploy the help contents using OHW-RC. One way to deploy OHW-RC  is to allow it to co-exist with your web application. The web application can be a JSF, ADF, JSP application or any JEE web application The OHW-RC could then be deployed as one of the web projects within the existing application.

Understanding OHW-RC Deployment Workflow as Part of Web Application

 Since OHW-RC will be part of an existing application, there are some steps that need to be done in the configuration of  the existing web application:
  • Veifying requirements and dependencies
  • Configuring the JEE Container
  • Installing the OHW-RC artifacts
  • Configuring OHW-RC configuration files

Verifying requirements and dependencies

To deploy OHW-RC as part of a web application, there are some requirements to be verified.

Requirement

Description
JEE Container The OHW-RC needs a JEE Container that could support Java Servlet 2.5\JSP 2.1 or later, JSF 1.2 (JEE 1.5). These containers are:
  • Oracle WebLogic Application Server Container 10.3
  • Apache Tomcat 6.x (not supported in 11gR1)
Client OHW-RC supports the browsers supported by ADF-Faces 11g. See the list of Supported Browsers.
Rich ADF Faces OHW-RC need the Rich ADF Faces libraries and their dependencies to be available. It should also be configured for ADF-based applications by installing the right jar files. This is generally done by using the adf.oracle.domain.webapp shared library. JSF 1.2 is also required

Configuring JEE Container

The existing container needs to be configured to support Rich ADF Faces since OHW-RC depends on that technology. Oracle JDeveloper, has a "ADF Runtime Installer" that will help you install the ADF libraries into the WebLogic Application Server Container.

Installing the OHW-RC artifacts

There will be serveral files you need to run the OHW-RC project: ohw-share.jar, help-share.jar, ohw-rcf.jar and ohw-rcf-webapp.zip,  which contains installable files like .jspx (xml style of a JSF page), images, css, and javascript files needed to run OHW-RC properly.
  • The ohw-rcf-webapp.zip needs to be extracted to the public html folder of the existing web application..
  • Create a helpsets directory under the public html directory.
  • Create an ohwconfig.xml file under the new helpsets directory.
  • The jar files (ohw-share.jar, help-share.jar, ohw-rcf.jar) should be put in a folder which is in the web application library path (such as public_html\WEB-INF\lib).
  • After adding the files, press the Refresh button on the Application Navigator in JDeveloper to have the window refresh.

Configuring OHW-RC Configuration Files

After all files have been placed in the right location, the OHW-RC administrator still needs to modify some configuration files to make the OHW-RC work.
  • Modify the application's web.xml file to include JSF servlet definitions and ADF Faces tags:
<context-param>                       
        <param-name>org.apache.myfaces.trinidad.CHANGE_PERSISTENCE</param-name>
        <param-value>oracle.adf.view.rich.change.FilteredPersistenceChangeManager</param-value>
    </context-param>
    <filter>
        <filter-name>trinidad</filter-name>
        <filter-class>org.apache.myfaces.trinidad.webapp.TrinidadFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>trinidad</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    <servlet>
        <servlet-name>resources</servlet-name>
        <servlet-class>org.apache.myfaces.trinidad.webapp.ResourceServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>resources</servlet-name>
        <url-pattern>/adf/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>resources</servlet-name>
        <url-pattern>/afr/*</url-pattern>
    </servlet-mapping>
  • Modify web.xml to support OHW-RC front servlets and JSF filter:
servlet>
        <servlet-name>OHW Servlet 1</servlet-name>
        <servlet-class>oracle.help.web.rich.OHWServlet</servlet-class>
        <init-param>
            <param-name>ohwConfigFileURL</param-name>
            <param-value>/helpsets/ohwconfig.xml</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet>
        <servlet-name>OHW Servlet 2</servlet-name>
        <servlet-class>oracle.help.web.rich.OHWServlet</servlet-class>
        <init-param>
            <param-name>ohwConfigFileURL</param-name>
             <param-value>/helpsets2/ohwconfig.xml</param-value>
        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>OHW Servlet 1</servlet-name>
        <url-pattern>/ohguide/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>OHW Servlet 2</servlet-name>
        <url-pattern>/blafdoc/*</url-pattern>
    </servlet-mapping>
    <!--This mapping is to support old OHW2 bookmarked URL. If you want to support
        OHW2 URL, please find out servlet mapping from web.xml in OHW2, add it
        here but change servlet to be Faces Servlet-->
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/help/*</url-pattern>
    </servlet-mapping>
    <filter>
        <filter-name>OHWRCFRequestFilter</filter-name>
        <filter-class>oracle.help.web.rich.OHWFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>OHWRCFRequestFilter</filter-name>
        <servlet-name>Faces Servlet</servlet-name>
    </filter-mapping>
  • Modify the ohwconfig.xml file you created and edit help content as needed. It specifies which helpsets to display and how to present them. You can also specify locales, branding information, and various other settings. For more information about this configuration file, please the OHW-RC Developers Guide on ohwconfig.xml. 
  • Modify faces-config.xml to add the ADF Faces render kit:
<application>
     <default-render-kit-id>
       oracle.adf.rich
     </default-render-kit-id>
     <locale-config>
      <default-locale>en</default-locale>
     </locale-config>
</application>
