Re: Setting up a new web-application
Hi Kevin, I'm using Xalan 2 in my framework and I've had the same problem with pretty much all the containers that I've tried playing with. With Orion, substituting xalan.jar and xerces.jar in the orion directory did the trick for me in 1.4.*. I think I remember I had to do something similar with Resin and I never tried with Tomcat. The problem seems to be something like the first XML library to be used is the one to be used for everything and as all the containers have nowadays XML configuration files and use an XML parser as soon as they start up, then the XML library that is used is the one that the container uses, hence the need to put your desired library in the global CLASSPATH. This can lead to problems that can't be solved, if the container and your application can only use incompatible versions of a parser. As somebody mentioned, I think JSDK 2.3 tries to solve this, specifically, Point SRV.9.7.2 Web Application Classloader (Page 63 JSDK2.3 PFD2) states: ... It is recommended, however, that the application classloader be implemented so that classes and resources packaged within the WAR are loaded in preference to classes and resources residing in container-wide library JARs. That should mean that the parser installed in the application classpath should be used in your applications over the one installed in the global classpath, but unfortunately it is just a recommendation so who knows what will happen :). Just my 2c, D. Kevin Jones wrote: and the point is that I shouldn't need to put the classes/jar in the Orion lib. I should be free to put whatever classes/jars I need in my own application. The only thing about this is that it is not an easy problem to solve (ask the Jakarta/Tomcat team), and for some reason it always seems to happen with XML/XSLT processors :-( Kevin Jones DevelopMentor www.develop.com snip...
Re: proxying orion with IIS or iPlanet Web Server
Hya... Got a reply for you :). I use Apache as a front-end server. I use Orion to store my EJBs, and I use Jakarta-Tomcat to deploy servlets and JSPs. Just put the Tomcat and Orion on one and the same machine, start tomcat with a classpath, that includes the jars of the Orion server. Put a jndi.properties file somewhere (probably the web-inf/classes directory) and specify the jndi properties as for a remote application: java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory java.naming.provider.url=ormi://127.0.0.1/your application java.naming.security.principal=admin user java.naming.security.credentials=admin pass Than you can safely read the Apache-Tomcat connectivity issues.

RE: bugs in @page extends=.... in Orion implementation?
Hi Juan I get your point about multiple inheritance, but say the web server would like all JSP pages to extend from class WebServerXYZPage, then one could just create a class which extends this web server class so that The JSP page EXTENDS MyClass which EXTENDS WebServerXYZPage This way, the web server has got room for its callbacks. Of course, this gives you a very tight coupling to the web server product (wherefore I for one would not use it), but I still don't see why this is not possible with Orion - I have been told that other EJB servers support this.

So, why use Orion?
Hi, I'm trying to collect together reasons for chosing Orion over other app servers - our company's been doing a lot of research into EJB technology over the last few months and currently the favoured choices seem to be JBoss and Weblogic. I can understand JBoss as a target environment - after all it's free. But I haven't seen a good case (yet) for using Weblogic; as far as I know it's pretty expensive and support actually seems a little lacking from what I've heard from others. From what I know it is pretty feature-rich though. Anyway, there's a chance for using Orion in preference (or at least as another official environment) given a solid list of reasons... Any ideas would be appreciated - performance, scalability, standards adherance, reliability, cost, platform availability, support, documentation quaility etc. etc. (I've been using it for a couple of months now and haven't had any trouble other than the usual learning 'glitches' :-) cheers Jules

Re: bugs in @page extends=.... in Orion implementation?
Hi, I've also used filters, but in this case to filter requests by IP, as I don't want certain IP's to be able to access certain URLs. On the other hand, I implemented security, logging and other features inside my own servlet Controller, following a Model 2 approach. I thought about externalizing this services as filters, but that would mean that the web.xml file will grow too much and that I would have to put too much things in the request object each time. It's not that I've discarded the idea, but I don't see any compelling reason to implement everything as filters. We don't use servlets, but ONE controller servlet and action classes and we use JSP as view-only, creatures (actually, we seldom use them as we use XML/XSLT), so as anyway all the requests go through my controller servlet...

Re: SV: proxying orion with IIS or iPlanet Web Server
Hi Patrick, I agree with you, in our case we are using Apache as a proxy for other reasons. One reason is that the Apache SSL certificate that we have doesn't work with Orion (quite easy to fix) but the main reason is that we use several instances of Orion, one per set of related applications, and we use the proxy to concentrate/redirect the traffic from the port 80 to the appropriate application port. This way we have one single point of failure, the proxy, but orion instances are independent of each other and we can start/stop/move them without bothering the other applications. Besides, we also have an SSI script inside the proxy that, in case an application server is down, redirects the request to the appropriate For maintenance reasons... page. Right now the proxy and the orion instances are, some of them, in the same host, but in the future I guess they won't be as next step for us is clustering. Anyway, no Tomcat anywhere and no plans for it, at least as it is now. We are quite happy with this set up, but we are in a situation were our main worry is not speed, so we don't care about the small extra trip between the proxy and the orion instance, but the number of applications.

Re: My Orion does not want to run the jsp and the servlets
Hasan, Make sure that you copy tools.jar from your java-dir/lib directory into the orion directory. This enables JSP compilation.

RE: Setting up a new web-application
I'm using Xalan 2 in my framework and I've had the same problem with pretty much all the containers that I've tried playing with. With Orion, substituting xalan.jar and xerces.jar in the Orion directory did the trick for me in 1.4.*. This is an ugly hack though :-) If another app using the same server and relies on Xalan-1 functionality, they're screwed. with Resin and I never tried with Tomcat. Tomcat 4 fixes this (mostly) The problem seems to be something like the first XML library to be used is the one to be used for everything and as all the containers have nowadays XML configuration files and use an XML parser as soon as they start up, then the XML library that is used is the one that the container uses, Yes, sort of. The problem is that the same classloader used by your web-app can also 'see' the global 'classpath ' set by Orion, and, as classloaders delegate, when the web-app CL tries to use an XML parser, or Xalan or something that is shared then the 'global' one gets used first. hence the need to put your desired library in the global CLASSPATH. This can lead to problems that can't be solved, if the container and your application can only use incompatible versions of a parser. As somebody mentioned, That was me I think JSDK 2.3 tries to solve this, specifically, Point SRV.9.7.2 Web Application Classloader (Page 63 JSDK2.3 PFD2) states: ... It is recommended, however, that the application classloader be implemented so that classes and resources packaged within the WAR are loaded in preference to classes and resources residing in container-wide library JARs. Yes, we put this in because of these sorts of problems. Kevin Jones DevelopMentor www.develop.com

Re: Orion running out of memory ?
Java? Memory leak? Um, not likely. Make sure you don't have some kind of infinite loop in your application. I did that once, and got the error after Orion grew to 512MB of RAM, used up all the swap space too, then orion tried to recover and it couldn't. If you ask me, I think it does a good job of handling situations like that. If you don't have an infinite loop, try to 'force' a garbage collect at some point in your test and see if it helps.

Markus, Thank you so much! Your answer combined with some of the stuff I've tried ended up being the whole solution. Here's the solution for those of you who may be having the same problems: - You have to run orion in secure mode. - You have to have a policy file to be able to run in secure mode (see my original email for the contents of my policy file). - Then you can read system properties from an EJB. But as Markus said, you can't write properties from your EJB code, so you have to have a properties file to set those. Here's the whole commandline syntax: java -Djava.security.policy=orion.policy -jar orion.jar -secure -p orion.properties I can't believe how much time this took to figure out.

Re: bugs in @page extends=.... in Orion implementation?
Hi! I have implemented these features as externalized filters. The reason for this was that I use a MVC 2 product which is developed independently (Jakarta Struts http://jakarta.apache.org/struts/). Like Marcel said the beauty of filters is that they are independent from the rest of the application. The filters allow me to plug in these services to the application without any integration code. So, I have a LogFilter which logs the requests using log4j (http://jakarta.apache.org/log4j/). After that there's an AuthorizationFilter which checks if the current user has priviledges to execute the request. AuthorizationFilter utilizes the forthcoming Java Authentication and Authorization service (http://java.sun.com/products/jaas/). All in all, I have a pretty flexible system with a very little own code.

I have a new problem in my application with runtime permissions.
The runtime error I'm seeing is:
java.lang.ExceptionInInitializerError: java.security.AccessControlException:

The commandline syntax for starting Orion that I'm using is:
C:\orionjava -Djava.security.policy=orion.policy -jar orion.jar -secure -p
orion.properties
I've tried a few different modifications to my orion.policy file, the
current state is:
grant codeBase file:/orion/- {
permission java.lang.RuntimePermission
accessClassInPackage.sun.net;
permission java.util.PropertyPermission *, read;
permission java.security.AllPermission;
};
grant codeBase file:/orion/applications/SystemAccess/- {
permission java.lang.RuntimePermission
accessClassInPackage.sun.net;
permission java.util.PropertyPermission *, read;
permission java.security.AllPermission;
};
// default permissions granted to all domains
grant {
permission java.lang.RuntimePermission *;
permission java.security.AllPermission;

Any suggestions?
Where can I find full documentation on what permissions may be set in Orion

Obviously Orion just ignores some permissions (like write to properties).

image/servlet caching issue
I'm having what I believe to be a image/servlet issue cache issue with Orion 1.4.5: Situation: I'm creating dynamically generated graphs based on an authenticated user. The images are created by passing values to a graph generating servlet. HTML looks like this: img border=0 src=/Incentive1Graph?mgmt01=37500min=10009target=25024gold=37535 where Incentive1Graph is a servlet that produces the image based on mgmt01, min, target and gold values. The very first time the servlet is run it produces the correct image. However, on any subsequent calls with a different user, the original image is returned. I think the image/servlet is being cached by Orion and thus, always returns the first image that was created. If I restart Orion, log in with a different user, the image produced is correct. Here's what I've done to debug so far: 1) Verfied the values for mgmt01, min, etc. are changing with different users 2) Deleted all files in the persistence directory 3) Deleted my browser cache 4) Tried with both Netscape and IE 5) Verified that I'm not accessing the test site through a proxy 6) Searched the Orion mailing list for similar issues Any other ideas??? My questions are: 1) how do disable image/servlet caching in Orion config? 2) is there something I can write in the Incentive1Graph servlet that will prevent it from being cached? Thanks in advance, Todd
Re: Orion running out of memory ?
We have had similar problems, using Orion 1.4.5. The first problem seems to be that Orion does not re-use instances... I beleive that the orion-ejb-jar.xml defaults to allow an infinite number of instances per EJB. If you are creating a lot of instances, this might help your problem. The second problem seems to relate to bug#251. If you are performing operations on entity beans, you might try setting their reentrant property to true and see if the problem goes away. If that works, I think it is a short-term workaround at best... I'm not sure how Orion handles entity bean reentrancy. Has anyone found these problems to be fixed in later (beta) versions of Orion?

We don't use servlets, but ONE controller servlet and action classes and we use JSP as view-only, creatures (actually, we seldom use them as we use XML/XSLT), so as anyway all the requests go through my controller servlet...

RE: bugs in @page extends=.... in Orion implementation?
Sure I will be happy to. The project I was involved in they factored a load of code in the JSP servlet superclass and I found that when I wanted access to this code via a servlet that it was impossible. Factoring code into the superclass is only useful if you've made the decision to only access this code from within your JSP pages at runtime. Sure there are many ways to architect this properly but reusing code factored into the superclass outside of a JSP pages is very difficult and putting such code in the superclasses encourages the use of scriptlets in the JSP code.

RE: image/servlet caching issue
First off, I have a similar servlet sending images running in Orion right now and it does not display this behavior (Although mine uses path info instead of request parameters so the URL still looks like an image). So I'm pretty sure its not Orion. Narrowing to a solution depends alot on whether the problem exists on the client or on the server. You should start out by forcing response headers to instruct the browser to not cache the results. This really can't do much harm so, its good to do even if the problem is on the server. Use these (assuming 'res' is an instance of HttpServletResponse) res.setHeader(Cache-Control, no-cache); res.setHeader(pragma, no-cache); res.setHeader(expires, System.currentTimeMillis()); If this doesn't fix the problem, I'd start looking at the servlet itself. I'd make absolutely sure that you have the appropriate things in the request scope verses the class scope. Its easy to miss something in the wrong scope and accidentally create this kind of behavior. -Original Message- From: Todd McGrath [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 30, 2001 11:25 AM To: Orion-Interest Subject: image/servlet caching issue I'm having what I believe to be a image/servlet issue cache issue with Orion 1.4.5: Situation: I'm creating dynamically generated graphs based on an authenticated user.

Maybe I'll just have to create an errorpage that handles this specific error.

Re: how to run jsps and servlet on orion?
Can you give a little more info? This is very vague... Jeff. On Thu, 31 May 2001 08:52:53 +0700 Hasan [EMAIL PROTECTED] wrote: i have created a simple web app (only using jsps). but orion didnt want to run them. any advice to solve it?
RE: So, why use Orion?
Hi, That's a tough call. Orion rocks in terms of performance, but they are far behind most others in documentation and support. JBoss is rock solid on EJB and has far more developers working on the project at any one time than I would say any other app server. Documentation is pretty good and you can't beat the price. The architecture of JBoss is pretty nice too. I think Orion's strongest points are its performance. Because it integrates the web server, jsp/servlet engine and ejb engine in a single jvm, its very fast. Ofcourse, you can run it in two tiers as well leaving one for ejb, and one for front-end web serving...nothing gigabit networking wont remedy in terms of network speed as the only difference in performance between running it on a single box in one jvm. I am interested in seeing how well Apache 2, Tomcat 4 and JBoss do as a team. Its a complete solution for web pages, servlets/jsp, and ejb and its all free and very well supported. I'd say the only downside to using free or cheap software is most companies simply wont do it because they are too naive to realize its good quality software. I still have yet to figure out why it is upper management involve political crap into the mix when it comes to choosing a good solid platform to deploy on. For some reason, if they have millions in the bank, they need to spend millions on the hardware and software otherwise they can't justify it. WebLogic 6 is very nice indeed, but you pay a premium, at $17K per cpu per server for a clustered setup, it can easily cost $100K for a site with fail-over and backup at dual co-lo's. Personally, I would use Apache 2, Tomcat 4 and JBoss for the reason of cost, documentation, performance and support. Orion still kicks all butts in sheer performance however. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Julian Richardson Sent: Wednesday, May 30, 2001 1:02 AM To: Orion-Interest Subject: So, why use Orion? Hi, I'm trying to collect together reasons for chosing Orion over other app servers - our company's been doing a lot of research into EJB technology over the last few months and currently the favoured choices seem to be JBoss and Weblogic. I can understand JBoss as a target environment - after all it's free. But I haven't seen a good case (yet) for using Weblogic; as far as I know it's pretty expensive and support actually seems a little lacking from what I've heard from others. From what I know it is pretty feature-rich though. Anyway, there's a chance for using Orion in preference (or at least as another official environment) given a solid list of reasons... Any ideas would be appreciated - performance, scalability, standards adherance, reliability, cost, platform availability, support, documentation quaility etc. etc. (I've been using it for a couple of months now and haven't had any trouble other than the usual learning 'glitches' :-) cheers Jules
RE: My Orion does not want to run the jsp and the servlets
Title: SV: ATM example -> deployment error -> PLEASE some HELP Make sure you copy tools.jar to the /orion root folder. Its used to compile jsp pages into servlets. It can be found usually in your /jdk/bin (or maybe its jdk/jre/bin) folder. -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of HasanSent: Wednesday, May 30, 2001 1:56 AMTo: Orion-InterestSubject: My Orion does not want to run the jsp and the servlets Hi, I have created a web application using JBuilder. I have followed the specification Orion made. I have tried to run the html files and they work fine. However, when I tried to run the jsps and servlets, Orion did not want to run them. What other files/jars I should copy or CLASSPATH, PATH, etc I should change? Please help me!! Thanks
