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"
<web-module id="strutsExample"
  • Modify the file $ORION_HOME/config/default-web-site.xml (or the configuration file for any other Orion web site) to include the following declarations, after the declaration for the <default-web-app> if any:
<web-app application="default" name="strutsDoc"
<web-app application="default" name="strutsExample"
  • 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:
  • 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:
      Therefore, you should be sure you do not store sensitive information (such as database passwords) in this file.
