Fw: Session Managment and Cache
Hi All, I have the following problems: with orion when my application creates a session it gets the old session Id.I mean if the session expired or my program invalide it, nex created session gets the old session id. Should it be a unique?I am asking because maybe my creation procedure is wrong or Is it normal for orion? And the second lets consider my jsp or servlets imports a package for example com.aaa.bbb.util and it contains some objects.If i change my jsp or servlets no problems orion runs the last compiled version of my servlet.But if i modify a class inthe com.aaa.bbb.util package and compile it,Orion still runs the oldest version of these class.It just runs the version of server startup time.So to validate changes i have to restart orion.Is there another way to od it? Any Comments Welcome. Thanx. Deniz

RE: Where is my stderr output?
if I understand you correctly what you need to do is check in your application.xml for the log file path=something.log / /log This will lead you to where your log file is located and if you haven't set it then simply set it by default I think most of the log files are kept in the ORION HOME\log folder John Creaner Software Development, e-Spatial Solutions, Ireland.

Re: Bug?!
You need to update your filter, the 1.5.2 was buit
on not yet finished servet 2.3 spec while the 1.5.4 is based on the latest and
finished servlet 2.3 spec.
Your generic filter should now looks like
this:
import javax.servlet.FilterChain;import
javax.servlet.FilterConfig;import javax.servlet.ServletRequest;import
javax.servlet.ServletResponse;
public class GenericFilter implements
javax.servlet.Filter{ private FilterConfig
filterConfig;
public void doFilter(final
ServletRequest request, final ServletResponse response, FilterChain chain)
throws
java.io.IOException,
javax.servlet.ServletException
{ chain.doFilter(request,
response); }
public FilterConfig
getFilterConfig()
{ return
filterConfig; }
public void init(FilterConfig
config) {
this.filterConfig = config; }
public void destroy()
{ this.filterConfig =
null; }}

Resource Adapter Assembly descriptor
Hello I'm trying to deploy a test resource adapter on the Orion server. My understand is that in addition to the standard J2EE deployment desriptor (ra.xml) I will need to write an application server spesific assembly desriptor (for JNDI binding etc). Do anybody out there know how to write such an desriptor for the Orion server ? Any help would be apreciated... Thank you.

RE: timed events
I have done this using the java.util.Timer class. I created a class that extends the TimerTask class, and calls the EJB. I made a singleton class that wraps the Timer class, so I can call it from the servlet layer to schedule tasks, and guarantee only one instance per VM. Thus, my EJBs aren't forking threads, so it should be OK. And the Timer instance, which controls the scheduling of the tasks, is always alive as long as my VM doesn't go down. I saved the schedule times and taskIds to the database so that they can be rescheduled when the appserver gets restarted. I created an application that reloads these jobs, and put this in client-module of orion-application.xml, so Orion would start it on startup. This works, and I haven't had any problems yet, but I'm not sure whether this is the best, or most valid approach. It feels a bit too easy to be any good. Alternatively, you can use a 3rd party job scheduler. This is free, and it has one: http://ofbiz.sourceforge.net/ http://ofbiz.sourceforge.net/core/docs/services.html I haven't had a chance to evaluate it. -Original Message- From: Johan Fredriksson [mailto:[EMAIL PROTECTED]] Sent: 13 March 2002 13:06 To: Orion-Interest Subject: Re: timed events Perhaps via a croned java client? //Johan - Original Message - From: Casper Højstrup [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Wednesday, March 13, 2002 10:20 AM Subject: timed events This more of a regular EJB question, I suppose.

Using NT security
Hi all, I checked thearchives and support pages for this, didn't seem to find it. Is there any way to get Orion to usethe NT username+password of whoever is logged in, for running client apps? Currently I'm reading them from a config file, which obviously is not ideal. Also, I am using the mail-session properties to configure a JavaMail session. Thus I have the userame+password of this hardcoded into application.xml. Anyone know of a way I could use the NT logged on credentials to specify the mail.smtp.user and mail.smtp.password properties of the session? It is an Exchange server. (Probably OT, apologies if it is). Thanks, Justin

It's doable, but far from straightforward or pleasant, plus there are plenty of holes in the protocol that are undocumented. http://www.innovation.ch/java/ntlm.html will give you a start. Of course, if you choose to go native, there's probably some dll somewhere that'll handle all this for you.
RE: Using NT security
Take a look at the sample JAAS modules that you can download from Sun in conjunction with JAAS. Specifically, they include an NT module which can be used to retrieve username and group information for a running process. Note however, there is no way to retrieve a password for a logged on user, at least not included with the JAAS module. The NT API does provide functions for retrievinga user's password, but in that case the domain/NTServermust be configured to store plain-text passwords, which is something most people don't do anyway. Exchange definitely offers an alternative authentication mechanism, but that falls outside of the standard javamail SMTP interface.

Fw: Re: J2EE Security issue...
repost.. One thing we added to what Rabi is doing is as follows: We track version with each object. If the user object is already on the session then we get it off and double-check to make sure that the version on the session is the most up-to-date. If it isn't, then we refresh that object on the session with what's in the database. This way we're guaranteed to have the most-recent user information on the session. This is all done in a filter that is mapped to everything, providing post-login processing. Jeff. On Wed, 13 Mar 2002 09:25:09 -0600 Satter, Rabi [EMAIL PROTECTED] wrote: I had the same issue. We did do it as a filter. However we checked to see if the a user context object (ie object where the informaiton was stored) existed in the session.

We've been using J2EE based security for some time now, its working great for us supporting several hundred users distributed across a handful of servers. Heres my issue - I have a set of things that happen on every page, a portion of which is looking for a 'new' login which then launches a series of things including doing database lookups, dropping stuff in the session, etc. Its occured to me that it would be significantly more effective if this was chained off the J2EE authentication, instead of checking on each page. I started looking into it and it looks like 1) its not part of the spec and 2) Orion has no specific implementation. The current implementation of J2EE security is so completely handled by the container that theres no way to get something in there. I then started going down the question of 'what is J2EE security except a filter?', so I could potentially chain a filter through there? It doesn't solve the problem because it still happens on each page hit.

Chained servlets and chained filters
I've got an interesting issue where I've got three chained filters running which all work great. One of these filters is a compression filter that modifies the Stream by compressing the final output. Unforutately I discovered that when the server sends a HTTP 500 response code, the result on the browser is not the typical ugly error page, but a blank page with a HTTP 200 response code. That won't do. I started looking through the J2EE spec and realized quickyl that the way to fetch the http response code is to deal with the raw stream (e.g. what Orion does, not me). Sure I can set the response code, but theres no way to examine find the HTTP status code. THe more I started thinking about this I started to believe this makes some sense, in almost every case you want the response code devlivered to the browser. The only time it becomes an issue is with doing chaining - and even then some chaining situations you still don't need it. It might be fair to say you only need to examine the status code when doing filters. Anywoo... Anyone given this a thought?
Another filter chaining question
I'm starting to get into some intersting space with filters and I've found yet another thing that seems like it would be a requirement for chaining filters. Order. It seems that theres no clearly defined way to know which filter will process a request first. I've been playing with placement in the web.xml and I don't seem to notice any particullar change in filter sequence. Anyone have any experience in this?

Hi,friend, Thanks for your reply. Yes, I tried every cases. And I also found the same problem when I tried to subscribe the e-mail. I don't know why, I also re-isntalled the low stable version 1.5.2, but same problems. By the way, I also have 2 questions: 1.Can you tell me where(the directory) I should put the jndi.properties file? 2.How can I list a directory(that means if I just give the directory name in the web browser, then the contents of the directory will be displayed in the browser)?
