JRUN 3.0 SP2A, VERSION 3.02A.11614

Tested with: Microsoft IIS 5.0, Windows 2000 テスト環境: Microsoft IIS 5.0, Windows 2000

Important Note:

重要なお知らせ:

At the moment, JRun is not fully compliant with the JSP 1.1/1.2 specification.

現在のところ、JRun は JSP 1.1/1.2 の仕様に準拠していません。

Specifically, the automatic type conversions for custom tag parameters specified in "Issue 7" of the JSP 1.1 Errata and in the JSP 1.2 Proposed Final Draft have not yet been implemented.

具体的には、 JSP 1.1 修正の "課題点 7" 及び JSP 1.2 最終ドラフト案にある、 独自タグのパラメータの自動での型変換に関する仕様を実装していません。

As it stands, JSP pages that make use of Struts taglibs whose parameters require conversion (such as booleans) will not compile under JRun. This includes the Struts Example Application. Attempting to run the example application will result in an exception similar to the following being thrown:

そのため、JSP ページを Struts taglibs を使用して作成し、 それらがパラメータの（ブール値などの）変換を必要とする場合は JRun によるコンパイルを行うことができません。 これは Struts サンプルアプリケーションにも含まれており、 試しにサンプルアプリケーションを実行してみると、 結果として次に示すような例外をスローします:

/struts-example/index.jsp:

javax.servlet.ServletException: Compilation error occured: 

allaire.jrun.scripting.DefaultCFE: 

Errors reported by compiler:
c:/JRun/servers/default/Struts 
  Example/WEB-INF/jsp/jrun__index2ejspa.java:41:1:41:27: 

Error: No match was found for method "setLocale(java.lang.String)".

The following instructions describe how to install the Struts Example Application under JRun. A subsequent section describes how the Struts Example Application can be patched to work with Struts

次に JRun 配下に Struts サンプルアプリケーションをインストールする方法について記述します。 後に続く章で Struts を動作させるために Struts サンプルアプリケーションにパッチを当てる方法について記述します。

The following instructions assume the following:

後続の記述は、以下に記述されていることを前提とします

  • JRun has been installed and integrated with the web server of choice.
  • $APP_SERVER_NAME is the name of the application server used to host the application. (When JRun is first installed, it creates an application server called JRun Default Server).
  • $APP_SERVER_DIR is the directory used to hold applications hosted by $APP_SERVER_NAME. For the JRun Default Server, the directory is $JRUN_HOME/servers/default where $JRUN_HOME is the directory where JRun is installed.

Installing the struts example application

Struts サンプルアプリケーションのインストール

  • Login to the JRun Management Console.
  • On the left pane, select $APP_SERVER_NAME. A page showing the current server status will be shown on the right pane.
  • On the right pane, click on the WAR Deployment link. A page containing a list of the currently deployed web applications will be shown.
  • On the right pane, click on Deploy an Application. Complete the Web Application Information form as follows:
    • Servlet War File or Directory: Enter the full path where struts-example.war is found or click on Browse to select the path.
    • JRun Server Name: $APP_SERVER_NAME
    • Application Name: Struts Example
    • Application Hosts: All Hosts
    • Application URL: /struts-example
    • Application Deploy Directory: will default to $APP_SERVER_NAME/Struts Example (or the name as specified for Application Name).
  • Once the form is complete, click on the Deploy button.
  • If deployment is successful, restart the application server by clicking on $APP_SERVER_NAME on the left pane. A page showing the current server status will be shown on the right pane. Click the Restart Server button to restart the application server.
  • Test the sample application by using the following URL in the browser:
    http://hostname/struts-example/index.jsp
    The struts-documentation.war can be installed using the same procedure.

Installing unpacked web applications

パックされていない Web アプリケーションのインストール

The above steps should be followed for applications deployed as *.war files.

For unpacked web applications, configuration involves the following steps:

以上のステップによって *.war ファイルによるアプリケーションの公開を行うことができます

パックされていない Web アプリケーションについては、次のステップを踏む必要があります:

  • From the JRun Management Console, select $APP_SERVER_NAME (on the left pane) and click on WAR Deployment (on the right pane).
  • On the right pane, click on Create an Application and complete the Web Application Information form as follows:
  • JRun Server Name: $APP_SERVER_NAME
    • Application Name: myApplication
    • Application Hosts: All Hosts
    • Application URL: /myApplication
    • Application Deploy Directory: will default to
      $APP_SERVER_NAME/myApplication
  • Click on Create to submit the form.
  • Once the web application is created, install and configure the struts components (struts.jar, struts*.tld, etc) for the web application under $APP_SERVER_NAME/myApplication/WEB-INF
  • Install the remaining components of the application: .class files, JSP pages,.properties files etc as required.
  • To configure the extension mapping of the request URI (ie *.do) to the action servlet, expand $APP_SERVER_NAME on the left pane, expand the Web Applications branch and click on myApplication. The right pane will display the configuration options for myApplication. Click on Servlet URL Mappings. A list of existing mappings will be shown. Click the Edit button and create the following entry:
    • Virtual Path/Extension: *.do
    • Servlet Invoked: action
  • Click on the Update button to save the changes.
  • Restart the application server.
  • The application should now be accessible from the browser.

JRun application server will need to be restarted each time one of the following changes are made to the web application:

JRun アプリケーションサーバは Web アプリケーションに対して、 以下のような変更を行うたびに再起動しなければなりません:

  • .class or .jar files are modified
  • .properties files are modified
  • .xml files are modified

Patching the struts example application

Struts サンプルアプリケーションにパッチを当てる

As mentioned at the beginning of these notes, the Struts Example Application will not run under JRun without modification. The following changes will need to be made:

この文書の冒頭で記述したように、 Struts サンプルアプリケーションは修正を行わなければ JRun 配下で実行することができません。以下の修正を施す必要があります:

  • index.jsp, logon.jsp: Change <html:html locale="true"> to
    <html:html locale=<%= true %>>
  • registration.jsp, subscription.jsp: Change all instances of filter="true" to
    filter=<%= true %>
