Installing Struts Examples on Orion 1.0.3b...
Hello fellow struts users ! I just want to share my experience with installing the struts example webapps on the Orion application server. 1. Locale problems The struts example application generated exceptions due to the fact that I'm running in the fr_FR default locale. The first exception was caused by the ActionResources.properties file not being found : 11/08/00 20:22 struts-example: Error preloading servlet javax.servlet.UnavailableException: Cannot load internal resources from 'org.apache.struts.action.ActionResources' at org.apache.struts.action.ActionServlet.initInternal(ActionServlet.java:541) at org.apache.struts.action.ActionServlet.init(ActionServlet.java:287) at javax.servlet.GenericServlet.init(GenericServlet.java) at com.evermind.server.http.HttpApplication.sw(JAX) at com.evermind.server.http.HttpApplication.si(JAX) at com.evermind.server.http.HttpApplication.sr(JAX) at com.evermind.server.http.HttpApplication.r6(JAX) at com.evermind.server.http.HttpApplication.init(JAX) at com.evermind.server.Application.q_(JAX) at com.evermind.server.http.dq.q_(JAX) at com.evermind.server.http.dp.j9(JAX) at com.evermind.server.http.dm.o9(JAX) at com.evermind.server.http.dm.o8(JAX) at com.evermind.util.e.run(JAX) I solved the problem by putting a copy of the ActionResources.properties file in /WEB-INF/classes/org/apache/struts/action/ActionResources_fr.properties. Wouldn't it be better to have a lookup that defaults to the ActionResources.properties file no matter what the default locale is ? 2. Problems with finding the action.xml file This is a know issue with orion for which the getServletContext().getResourceAsStream(config); call doesn't go into WEB-INF. I modified the web.xml mapping for the taglib to point to /action.xml and moved the file to /action.xml to fix this. Wouldn't it be better to access this file as in the example Database servlet ? getServletContext().getRealPath("/") + "/WEB-INF/database.xml" 3. Problèmes with the jaxp...

Wouldn't it be better to have a lookup that defaults to the ActionResources.properties file no matter what the default locale is ? I will have to look at this one. I would expect java.util.ResourceBundle (which I'm using to read this file) would do exactly what you describe, according to it's Javadocs. 2. Problems with finding the action.xml file This is a know issue with orion for which the getServletContext().getResourceAsStream(config); call doesn't go into WEB-INF. I modified the web.xml mapping for the taglib to point to /action.xml and moved the file to /action.xml to fix this. Wouldn't it be better to access this file as in the example Database servlet ? getServletContext().getRealPath("/") + "/WEB-INF/database.xml" This approach will only work if your servlet container is actually running the webapp out of a directory structure. On containers that run an app directly from the WAR file (or some other internal organization), getRealPath() will return null and the above call will not work. The servlet spec issue that led to this has been clarified -- ServletContext.getResource() is allowed to access static resources from within WEB-INF -- but the container is not allowed to return these contents directly to a client. I understand that the newest version of Orion has been modified to change this. 3. Problèmes with the jaxp...

Re: Clustering help..
Hate to just chime in, but I would love some information on this as well. Not only instructions and documentation for it, but a list of clustering features that are supported would be great too. - Original Message - From: "Keven Duffey" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Saturday, August 12, 2000 5:28 PM Subject: Clustering help.. Hi, I have yet to figure out how to cluster Orion. The documentation still leaves a lot to be desired. If I have two separate machines, how do I get two Orion servers to talk with one another? Can I have one be the servlet engine, and one be th ejb engine? How about fail-over? Ideally I want two (or more) web server/servlet engine front-end boxes, and two or more EJB boxes. Can someone shed some light on how to get this to work. Initially I need the fail-over servlet engines, because I am not doing the EJB stuff yet. So how would I set up two boxes to be fail-over, scalable and load-balanced with Orion? How do I add more computers to one tier? Thanks.
Creating a JNDI entry
Hello I'm trying to access an EJB through RMI. I can get hold of the context, but I'm not sure how to assign the bean a JNDI entry under Orion. Could someone tell me how this is done? Thanks
