Orion freezes on lookup
Hi! Perhaps somebody can explain this: Server is Orion 1.3.8,1.4.5 and 1.4.8, jdk 1.3.0 on Linux. We packaged two ejb jars and two WARs into one EAR. Everything works fine, except when we want to lookup one BMP bean. The call to ctx.lookup(..) freezes the whole app server. But if we first start the orion console, open the Context of the application and click on the bean, everything works as planned. All ejb-ref entries are present. t.i.a.

RE: Pure Corba client and Orion
Orion is not an IIOP-based server. It uses client stubs to communicate using the Orion RMI Protocol (ormi). If you need to access EJBs from a pure CORBA client, you have three options I can think of: Write your own RMI proxy Use some sort of HTTP-based RPC mechanism Use an app server which speaks IIOP natively There seems to be something of a religious war over the issue of stubs/proxies vs. IIOP. There is a lot of interesting discussion in the EJB-INTEREST archives about this.

Re: User/Role problem (solved)
There was an other method permission set on findByPrimaryKey(). Orion obviously calls this method for a remote object when you call a remote-method on that object (presumably for uptodate-checks). Thus a remote-method may only be invoked by a user that belongs to roles for both the remote-method in question and for any subsequently needed Home/Remote methods. Pretty obvious when you look at it that way, isn't it? Only methods implicitly called by OrionServer are not always that obvious. ;-) Yours Armin Michel On Tuesday 08 May 2001 15:52, you wrote: Following situation: - I restricted method permission of method foo to role bar - if I do: roleManager.addToRole(ctx.getCallerPrincipal(),bar); foo(); everything works just fine. - if I create a (temporary) user (e.g. user123), add him to role bar then log him in with the RoleManager and finally do a foo(), I get as security-exception.

RE: User/Role problem
Are you using the default user manager (the using the principal files)? In that case it is easy to check what's happening by adding roleManager.store() in your code. That'll store all your changes in the principal files. After that it's piece of cake to check the relations. 'user123' should be member of one of the groups that are mapped you your 'bar' role (i.e bar group). I can remember I struggled some time ago with the RoleManager and the UserManager as well. After a while I realized that the offer RoleManagement plus some convenience methods (like createPrincipal) which sometimes gets confusing. The UserManager should manage users and groups, the RoleManager manages roles and stores changes to persistence (why can't you do that using the UserManager ?).

Re: User/Role problem
On Tuesday 08 May 2001 17:14, you wrote: We have had similar problems, and I have reported them to orion (but they said they couldn't reproduce the problem). Here is what I found. If you have an EJB method foo(), and you restrict its access to a role MYROLE, then a user who, according to the XML files, should have access to foo() is denied access. If, however (and quite contrary to specs) you specify a GROUP name (e.g. MYGROUP) instead of a ROLE name (e.g. MYROLE), then access is granted (assuming your user is in that group). I would be very interested to know if you can confirm this. Probably yes. IMHO, Orion forces me to specify a group for every role that I define. I can only do a addToRole(bar) when I have a group defined that bar is mapped upon. Your problem may be closely related to mine, but I think my problem is still another one.

Re: Share sessions????
Hi Tomas, AFAIK, you can't do what you want to do, as sessions are not shared between different applications. When you try... disp=context.getRequestDispatcher(/app2/app2.jsp); disp.forward(request,response); from inside your app1 application, you are really forwarding to /app1/app2/app2.jsp, hence the 404 not found. And when you try sendRedirect(), you are asking the BROWSER to issue a call to the second page, and the browser knows nothing about server side sessions so that's why your attribute doesn't get through. Unless both jsp pertain to the same application, I don't know of any standard way of directly sharing objects between webapps. You might have to use something external. I guess the philosophy behind that is if they have to share, they should be part of the same webapp which can be seen, IMO, as a security feature and a limitation. As a non standard way of doing it, you might be able to use the parent attribute in the orion server.xml configuration (http://www.orionserver.com/docs/server.xml.html), but I'm not sure it allows you to do what you want to, as I have never used it. Does anyone know if there is a standard solution for this? regards, Dan Tomas Anderson wrote: Hello. I hope someone can help me with this basic question. I have 2 separate applications, app1 and app2. One jsp and one servlet in each. From the jsp I send some parameters to the servlet.

RE: Caching XLS style sheets
Excel stylesheets? Perhaps you mean XSL :-) If you use the JAXP 1.1 transforms api, creating a Templates object should produce a precompiled version of an XSLT. Although this will be completely dependent on implementation, I don't believe any implementations actually compile to bytecode - really precompiled means preparsed and maybe stored in a format for efficient processing. On a related note: A friend and I are nearly finished constructing a simple MVC framework with sophisticated XSLT support. We will be publishing it with an Apache-style license in about a week. Cool things this framework does: . Output from a view can be run through a config-defined sequence of iterative XSLT transformations. . The JavaBeans model returned from a command can be automagically adapted to a DOM for XSLT transformation without JSP, XSP, or any other templating language. Efficiently go directly from java beans to XSLT. . The transformation process can be halted at any step, allowing the XSLT creators/designers to work from static XML generated from the previous step(s). . Other templating systems can be used to feed input to the transformation process, including JSP and Velocity. Plain XML inputs can be used as well. . XSLT transformations are not required. It's still an elegant MVC framework for simple JSP/Velocity/? - HTML processing. I've attached an example configuration file so you can see the kinds of things you can do with the framework.

You need to take five steps: 1. First tell the server where the app is in the server.xml file (this is in the config directory). Add this line between the application-server tags: application name=someapp path=/path/to/someapp / 2. Create a directory the reflects your /path/to/someapp above. Add a directory, /path/to/someapp/META-INF. 3. Create an application.xml with the following content, and put it in the META-INF directory: ?xml version=1.0? !DOCTYPE application PUBLIC -//Sun Microsystems, Inc.//DTD J2EE Application 1.2//EN http://java.sun.com/j2ee/dtds/application_1_2.dtd; application module ejbEJBS.jar/ejb /module /application 4. copy your EJBS.jar to the /path/to/someapp directory. 5.

RE: Sybase
You probably still have the deployment directory with references to the old cmp deployment in Hyprersonic. Blow away the application-deployment directory, or your app directory in the application-depoyment directory, and you should be ok. No need to change the sybase.xml -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Markus Härnvi Sent: Wednesday, May 09, 2001 6:29 AM To: Orion-Interest Subject: Sybase Hi! I'm using Hypersoniq for development and Sybase ASE 11.9.2 for deployment. I am storing some TreeMaps in a CMP Entity Bean. In Hypersonic it will be stored in a LONGVARBINARY. However, when I try to change the data source to Sybase it still tries to create a LONGVARBINARY field, and Sybase doesn't like that. Is there something I have to add to sybase.xml? /Markus -- Markus Härnvi Altcom AB, Sweden
Apache + Orion
Could somebody please provide with a workable set of instructions on how to integrate orion and apache. I followed the instructions available on orionsupport.com and got the apache proxy part to work, but url rewriting is still not working. I'm also not quite clear where the web-site.xml file goes in this configuration. Your response is greatly appreciated.
common practice for configuring orion app/web-site
Hi, This might be sort of a newbie question or just a very general one. I tried looking through archives before posting but no luck, maybe someone has a quick anwser. I would like to know if most of you break up your projects into a lot of small apps and bind this to a web-site, or do most of you just pile all the apps into one big one.. so that there is only one application running on one default-web-site. -p __ Do You Yahoo!?

Re: log4j and ejb usage ??
Sorry that I posted the message three times. I was having a fight with my mail program! Eddie From: Eddie [EMAIL PROTECTED] Reply-To: Orion-Interest [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Subject: log4j and ejb usage ?? Date: Wed, 9 May 2001 16:13:50 +0200 Hellu there, I wan to use log4j to do the following: - Log a message and send an email if this concerns a log message of typ=ERROR. - Keep track of the logged message, so that a email is only send once and not every minute when the same error keeps occuring. Does anyone has any advice on how to do that. I was thinking about putting it all in a session bean ?? Then what should I choose: stateless/statefull ?? I think that is best to give every application his own session bean, but I can only do this by making the bean statefull. But if it statefull, the application will have more session beans, as it is possible that more than one client connect at the same time!!

Re: BIG Problem with SSL
robert, check out the shared attribute of a web app in the orion docs. it's designed allow two different web apps to share sessions. i.e. in the appname-web-site.xml file, set web-site web-app shared=true/ /web-site for both the secure and non-secure apps. cheers, greg - Original Message - From: Robert S. Sfeir [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Wednesday, May 09, 2001 5:19 AM Subject: BIG Problem with SSL When I setup SSL under Orion and I hit: http://www.domain.com then hit https://www.domain.com they both come up fine, but it looks like Orion is starting a new session!!! This is bad because if someone is logged in under https, it doesn't look like they're logged in when they're under the http server. Am I missing a setting with SSL or is this normal Orion behavior? Thanks for any prompt response you might have. R

XSL blahs
Howdy yall, I was a subscriber here some time back but had to get out of my mail lists (I cant delete, er, read 1000 emails every evening..;) Im back to playing with Orion, I upgraded to ver 1.4.8 and found the automatic XSL translation on my pages is now broken. It seems to be nullpointer error from the XSLServlet somewhere. Anyone else have the problem, and anyone know of a solution? I saw others had XML problems with this ver, but havent seen anything in the archives addressing this.

Well, I spent all evening to discover I didnt have the encoding specified, so a special character buried in a huge xsl was causing this error.

Re: Database Connectivity Problems
Thanks for pointing me in the right direction. The network adapter error came from the way Oracle MTS handle JDBC calls. Even if you call it by using an IP Address, when it responds back with the connection information it sends a hostname even if the JDBC driver made the original call using an IP address. The JDBC driver made the connection, which I could see in the listener.log file, but when oracle told it to close the connection and reconnect at the specified port on hostname the JDBC driver closed it's original connection and got lost trying to resolve the hostname, since it hadn't gotten added to DNS yet. Kep In a message dated 5/3/01 4:31:52 PM Pacific Daylight Time, [EMAIL PROTECTED] writes: This message comes from the JDBC Driver NOT from orion... We get that error when there is something wrong with the DB (i.e. down, etc) . Also the JDBC driver your are using should match the Orcale db version you are using. Thanks, Claudio
