I also got an error when I deployed my ear from Sun's J2EE server but I got a pretty detailed description of what orion didnt like in the XML files. With this information I could unpack my ear and fix the XML file and succeed to redeploy it. Some SUN specific information is stored in a sun...something...xml file for each bean.

Re: Trouble with session between JSP and Servlet
Hello. I had the same problem. It was because of the browser. JSP location: http://myserver.com/Init.jsp The JSP redirected to the Servlet after it does it's job. BUT! The redirection went to: http://www.myserver.com/servlet/MyServlet The browser (IE) did not recognize this to be the same server and restarted the sessionID. So Orion thinks it is a different client. Test: try to access the JSP via: http://www.myserver.com/Init.jsp Then the redirect should work. Another problem is, that the Session cookie is bound to a start location: Cookie: JSessionID=1235r4123; path=/RootContextPath. Again the browser dows not recognize this cookie to be sent, when you try to access /servlet/* That is why I was forced to use filters, so that /RootContextPath/MyServletService/* was bound to MyServlet, and it worked. Try these things. They might help. Additional info is required for further investigation. May the shade of the tree strengthen you. Lachezar. I have a JSP and a Servlet in the same war file. Both URLs have been setup with security-constraints in the web.xml. When hitting the JSP first I am prompted to authenticate, which is expected behaviour. After authentication I then goto the Servlet and I am then again redirected to the login form and asked to authenticate. Has anyone else had this problem? Seems like being in the same war file the first authentication of the session should work for the entire war file. Thanks

Just some catches: .- In the Error pages, ALL the links have to be absolute and start with a different name than the proxied path. Otherwise you get an infinite loop between the proxied page and the error page. So make sure that nameX and localApacheDirX are ALWAYS different and that all links in localApacheDirX/index.html start with /localApacheDirX or http://. .- If inside the applications you want to get the real remote IP instead of the proxy one, then you can use, for example, the mod_proxy patch written by Bjoern Hansen which includes the original IP in an http header (X-Forwarded-For). We used it because we needed to implement IP based security restrictions, which are not defined in the JSDK spec. We also used this IP based security restrictions to prevent acces to the applications by-passing the proxy, which is very important with SSL protected applications. .- It also works with ssl. .- To improve performance, you can also use the apache proxy as proxy-cache, to get the static content faster, but then be careful not to allow it to cache the dynamic pages you don't want to be cached. And make sure you have enough disk space ;). .- We haven't specified and ErrorDocument directive for the code 500 (internal server error) because we wanted to be able to see this kind of messages, but you can put it later on to show more graceful messages. .- We use SSI to define the error hanlding page, but you could use a JSP if you wished. We just did it to have a light weight proxy with no special add ons. I hope it helps, D. Eddie wrote: Daniel, The way you do this with Apache sounds very nice.

What we do is put an Apache web server, acting as a proxy, in front of the orion server. Then, in the proxy configuration you can specify a redirect page in case something goes wrong, and we use it to redirect to a SSI script that determines which application is down and which page should be shown as an error message. This way you show automatically an error message, just by shutting down orion or by returning a 500 code from your application. I hope it helps, D. David Pérez Villanueva wrote: Hi!

RE: BodyTagSupport
A couple of things I noticed.
1) Your HTML does not specify the count so the body is skipped.
2) You rely on the tag engine to do your looping. While this may work if the
engine is not correctly implemented then it won't. I would just do the
looping in the doAfterBody. That way you have all of the body contents and
you have the count.
Hope this helps.

Various levels of security, how do you do it?
We are in a process of developing an application, and are looking for ways to implement security, we have the following requirements: 1. There are operations that certain members cannot perform in general 2. There are operations that certain members cannot perform relative to an object (owner vs non-owner) What are some of the mechanims that you are using to deal with these problems. I assume, in the first case you can use deployment descriptor. Also isInRole query can be made to determine if particular option should be shown to the user during the .JSP processing. The second option is a bit more difficult to implement, since a particular user can be an owner of some objects but not others. How can this requirement be implemented? Thanks. -AP_
