## 6.2 Installation

### Installing Struts with your servlet container

#### Orion Application Server

In the steps below, `$ORION_HOME` refers to the directory in which you have installed Orion, and `$STRUTS_HOME` is the directory in which you unpacked the Struts binary distribution.

- Modify the file `$ORION_HOME/config/application.xml` to define the two new applications, by adding the following declarations, immediately following the `web-module` directive for the default web application:

    <web-module id="strutsDoc"
                        path="$STRUTS_HOME/webapps/struts-documentation.war"/>
                        <web-module id="strutsExample"
                        path="$STRUTS_HOME/webapps/struts-example.war"/>

- Modify the file `$ORION_HOME/config/default-web-site.xml` (or the configuration file for any other Orion website) to include the following declarations, after the declaration for the <default-web-app> if any:

    <web-app application="default" name="strutsDoc"
                        root="/struts-documentation"/>
                        <web-app application="default" name="strutsExample"
                        root="/struts-example"/>

- After you start Orion, you should now be able to access these applications (assuming you haven't changed the port number from the default of 80) at:

    http://localhost/struts-documentation
                        http://localhost/struts-example

- Versions of Orion up to at least 1.0.3 have a bug related to ServletContext.getResource() calls that prevent the Struts example application from working out of the box. This manifests itself as a JSP error when you try to access the example application, with the following message:
  `javax.servlet.jsp.JspException: Missing resources attributeorg.apache.struts.action.MESSAGE`
  followed by an error traceback. There will also be an initialization error message in the `ORION_HOME/log/global-application.log` log file. To work around this problem, you can take the following steps:
  - Go to the `$STRUTS_HOME/webapps` directory, where you will note that Orion has automatically expanded each web application into an unpacked directory structure.
  - Go to the `$STRUTS_HOME/webapps/struts-example/WEB-INF` directory, and copy the file `struts-config.xml` one directory up (that is, into `$STRUTS_HOME/webapps/struts-example` .
  - Modify the `$STRUTS_HOME/webapps/struts-example/WEB-INF/web.xm` file, changing the value of the "config" initialization parameter (for the action servlet) from `/WEB-INF/struts-config.xml` to `/action.xml` .
  - Restart Orion, and you should be able to access the example application.
  - Note that this workaround has a negative security-related side effect: your `struts-conifig.xml` file can now be retrieved by remote clients at the following URL:
    `http://localhost/struts-example/struts-config.xml`
    Therefore, you should be sure you do not store sensitive information (such as database passwords) in this file.
