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.
