I would like it to be XML centric, and MVC. For example, the V should apply the XSL to XML, to make it HTML. It should do standard session tracking. It should do standard data manager, so that Java Beans do the SQL (the M). A minor plus is form entry management and a bit of image/content management. It should be a single rich framework.

Re: Is this a 1.4.8 bug??
Yep that sure is a bug. I and Jeff had the sam thing and Jeff logged it under bug number #414. Add your configuration to the bug (I still have to do that to) so that they have more info to work on. I hope they resolve it soon so I can go back to 1.4.8, as things were looking good.

Using SSL from within an EJB
Hi! Ny1 ever tried to open a SSL socket from within an EJB (lets say stateless session-bean) As far as I know it's "legal" to open a client socket which is what I want to do, but I want to make it a secure socket (using SSL). Lars Borup Jensen email: [EMAIL PROTECTED]
Advanced OR mapping
Hi, I'm having some problems with the OR mapping, especially for entity bean reference mappings. Although I've gone thru the Advanced Object-Relational mapping topic on orionsuppurt.com, I'm unable to transfer this to our object model, i.e.: EJB Product has references to - ProductType - Supplier which references to - Country - PackingUnit and also has Collections of - Attributes which references to - AttributeType - Prices which references to - Currency - ClientType - SalesTax - Medias which references to - MediaType - AccessoryProducts which are of the same type as the Product itself. So it's quite complicated and maybe someone can give me some directions of what to do. For me it's very important to see, whether for this model Orion CMP works better (in regard to performance) than the existing BMP, as I've seen that it's faster for simple EJB's TIA Joerg
RE: MVC/XML Framework Comments please
Title: RE: MVC/XML Framework Comments please Thanks everyone. I will first say that I have asked a similar question in 2 newsgroups and another mail list. The Orion Mail list gave 10 times more input and 10 times higher quality than any other mail list. Here is what I plan to recommend. We will use Data Access Object in the back (so we can change that to be an Astral Clones Pattern later). This ADO layer cache transparently. I am leaning towards Jet Speed in the middle, because it has Portal capabilities. (A 2nd part of our application that need to be high speed will be hand crafted). In the presentation, I plan to do similar to bellow, or XSLT with pre compiled cached sheets. It is interesting to not that there is an upcoming Java One session that talks about using JSPs for XSLT somehow, and I will go to it to see what that is about. Again, thanks for great input to the a dozen who responded. Vic -Original Message- From: Jeff Schnitzer [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 26, 2001 4:11 PM To: Orion-Interest Subject: RE: MVC/XML Framework Comments please Your message is very timely, because I'm currently doing the same sort of research. I wrote my site ( www.similarity.com http://www.similarity.com , an amusing basement project) using Rickard Oberg's WebWork MVC framework to produce HTML directly, but now my team and I are exploring more sophisticated options. My desire is for an MVC framework which generates XML. The XML would then be transformed with XSLT on the way out by a filter. Orion already does this transformation if your output is XML; take a look at $ORION_HOME/default-web-app/examples/xsl. So it really doesn't matter what MVC/templating framework you use as long as you generate XML; Struts would work fine. In fact, yesterday we wrote a spike solution using Struts (which now works out-of-the-box with Orion 1.4.8) to generate XML and transform it using the stylesheet tag in the XML document. It works great. I've been spending a lot of time researching MVC frameworks, and I'm happy to offer my thoughts so far: In the pure form, there are three stages we wish to isolate in building our html (or wml, or whatever) pages: Logic (the algorithmic world of code), Content (the meaninful information which may be static or may have been generated by logic), and Presentation (content transformed into html, wml, pdf, or whatever can be attractively rendered for display). MVC frameworks like Struts and WebWork do not distinguish between Content and Presentation. Really the MVC Framework just covers the first two phases of a Web Publishing Framework. The third phase is covered by XSLT transforming filters applied to the View after generation. Orion provides this automatically. Within the MVC process, however, there is another templating/transformation process to build the Content from the Logic. Some frameworks (Struts and WebWork) use JSP optionally with custom tag libraries. Some frameworks (Turbine) allow you to plug in a variety of templating systems, such as Velocity. Cocoon uses XSP (Xml Server Pages). This is entirely independent from the Content to Presentation transformation process which occurs later using XSLT. It sounds like Tim has a homebrew system for going directly from Logic to Presentation. My team has been thinking of eventually writing a wrapper to expose JavaBeans (the model) as a DOM using reflection so you could still have a pull-based system rather than having to build the full tree ahead of time. I'm not sure it's ultimately desirable to skip the Logic-Content step, although it would improve performance. As far as specific frameworks go: Cocoon is the most comprehensive solution. Cocoon2 sounds like it's going to be even better. I'm not too fond of this framework though because you have to be able to stomach XSP. The syntax isn't very elegant, IMHO. I didn't look too closely at how their controller system works. Struts is pretty complicated, but it has a large support community and a lot of developers working on it. For a templating system you can use either straight JSP or their elaborate set of taglibs. It provides good delineation of M, V, and C but it feels like you're programming fairly close to the servlet api. I'm sure this is easily avoided with a few support classes. Struts seems to be the favorite framwork of the Sun blueprints authors, which gives it a lot of longevity. WebWork is very much like Struts, but simpler (good), less mature (bad), and lacking a development community (fatal). The author is a smart guy, but he's just one guy, and he doesn't seem interested in moving the project towards a community development process. One thing I *don't* like about WebWork is that it tries to abstract the MVC system away from servlets so that it could conceivably be used with Swing as well. This makes doing simple things like issuing redirects rather than
Have you clustered orion successfully? Please contact mchristoff@eldan.com
Hello. This is just a friendly plea to those who have successfully clustered orion to contact me at Eldan Software. We have already commited to using orion and currently have a *production* web application running off an orion server. The client company has now asked us to add two more servers to serve their web application. At the time we went with orion we knew we would eventually have to cluster them. From from reading the how-to doc and reading comments on how easy orion clustering is to set up we were confident we could promise the client we would cluster orion without having tested it :(. Now we are in the position that orion *is* clustering correctly *but only the default-web-app*. It will not replicate session state for any other web applications setup in the default-web-site.xml file. We followed the setup instructions to the letter: (NOTE: All of these steps were taken for both servers) 1) We tested our web app individually on our two test servers and they ran correctly. 2) We added the cluster-config/ tag to orion/application-deployments/default/defaultWebApp/orion-web.xml. According to the docs: If you want to add clustering for the whole website (for all web-applications), edit the orion-web.xml of the default web-application We are using orion 1.4.5, so according to the docs ALL of the web applications defined in default-web-site.xml should be clustered. 3)We added the cluster-island=1 to the default-web-site.xml file in the web-site tag. Note that all the applications we are testing are defined in the default-web-site.xml, ie: web-site host=ivan port=8080 cluster-island=1 display-name=Default Orion WebSite frontend host=groovy port=80 / default-web-app application=default name=defaultWebApp / web-app application=TestApp name=TestApp-web root=/TestApp / web-app application=Test2 name=Test2-web root=/Test2 / Note that we also changed the 'host' attribute in the web-site tag from [ALL] to our actual hostname. 4) As you can see from step 3) we added the frontend-host tag with the location of the loadbalancer to the body of the web-site tag in default-web-site.xml 5,6) We started the load balancer on our server named groovy then started our other two servers. The lodablancer successfully noticed our other two servers and added them to cluster island 1. 7) Lastly we tested the session replication using the servlets/SessionServlet servlet. We modified the SessionServlet servlet, adding one line that posts the ip of the server its being run from. We then re-compiled the session servlet and to be safe, stopped the loadbalnce, stopped both orion servers, restarted the load-balancer and both servers (again, the load balancer found both servers). We then ran SessionServlet and found the ip was from server2, we refreshed the page until the counter went up to 5. We then shut down server2 and refreshed again, and lo-and-behold the counter went up to 6! Yeah! We thought we were done with clustering. The Problem We then copied the code for SessionServlet into a JSP called session.jsp. We put the jsp in the TestApp-Web directory and tried the same test. THIS time the counter went back to 1 when we ran it. This boggled us. We then copied session.jsp into the directory orion/default-web-app and tried it. IT WORKED!! We did not change a line of code. This is an exact recreation of our problem with orion session replication. We followed the docs exactly. If you have gotten clustering to work properly, we would appreciate greatly if you could share your knowledge with us. We are at an impasse and cannot figure out what to try next. Just for completeness, here is our server.xml file, perhaps we are missing a setting in this file(?) ... application-server application-directory=../applications deployment-directory=../application-deployments rmi-config path=./rmi.xml / principals path=./principals.xml / log file path=../log/server.log / /log global-application name=default path=application.xml / global-web-app-config path=global-web-application.xml / web-site path=./default-web-site.xml / application name=Test2 path=../applications/Test2/ auto-start=true / application name=TestApp path=../applications/TestApp/ auto-start=true / ...

install issues
Every now and then I do something that reminds me I am human. I am trying to use 1.4.8 with the autoupdate. This usually works fine, but I have been working on a machine which I unzip from win98 onto a samba directory in linux. This is great, because all of the permissions expecially the X for the directories is preserved, as well as the time stamp. But on a straight linux box, an unzip -X orion1.4.5.zip will not give you X on the directories, which of course makes them useless. I want to use unzip, since it preservse the timestamp...which is necessary for autoupdate to work. What am I doing wrong? regards, the elephantwalker .ps I am running as j2ee user, since I am useing ipchains to redirect my 80 packets to another port.
