Re: idea=$395.00USD was: RE: Java IDE?
IDEA has rediculously high ROI. And it's normally high productivity is skyrocketed if you are refactoring because of all the advanced refactoring features it has. IDEA was written by people who apparently actually use the editor they're selling. JBuilder is probably used for JBuilder, too, but look at how long it takes Borland to crank out new useless features; Intellij does it every week. I've used JBuilder for years, and have recommended it often. However, IDEA is simply way more productive, and appropriate to the way I work. Refactoring is the major advantage IDEA has over anything else I've tried (which includes codeguide). I am now more evolutionary in my programming approach, iterating toward the proper packaging and naming of things later in the project when the issues of feasibility and functionality have been settled. Often the cost/tediousness of repackaging classes (for example) in a normal IDE, is such that you just avoid it, if at all possible. I'm an independent contract developer, and I normally pick up free or inexpensive software tools (Net beans, jedit, ant, Metamill, etc). For me to commit US$400.00 to an IDE is sincere testimony to the productivity of IDEA. It has saved me probably a hundred hours development time in the last 6 months, and my products are better structured than they would otherwise be. However, I wish intellij would drop the price. More developers (including clients - why dont you use our jDeveloper?) should know the joy of immediate refactoring. Oh well, its intellij's business model. I suppose those excluded by the current pricing will just have to wait a few months for the open source and competitors (Borland ?) to come up to speed. Bill Winspur.

Re: Shutdown causes Address in use: JVM_Bind
Stephen, Andrew, After I posted this issue, I noticed that the problem was application dependent, i.e. when my web appwas invoked from an applet, shutdown and startup work as advertised. However, when the web appwas invoked frommy client app, in which I use a URLConnection object to talk to the web-app, subsequent shutdown and startup exhibited the address-in-use problem. The fixwas to do a disconnect() on the client app's URLConnection (casting it to an HttpURLConnection). The implication is that the browser (IE 5.0) is already well-behaved in this regard, so applets did not exhibit the problem. As to why this client-side problem affected the webserver, Iassumeit is because the web-server and client share the same TCP stack (I'm developing in loopback mode at present). I'll check that assumption later on, when Ideploy tothe real server.

Re: Class.newInstance() Fails with InstantiationException.
Thank you Stephen. That nailed it. The
problem was not so obvious to me.
Although the API doc for
Class.newInstance(), does not state it explicitly, you must code a no-args
constructor into the class to instantiate it using newInstance(). Replacing my 1
arg constructor witha no-argconstructor and a setter method fixed my
problem.
The behaviour of of Class.newInstance() and
Class.create(object), which implements programmaticinstantiation using
constructors with arguments,is documented in theJava
Tutorial. RYFM strikes again.

Class.newInstance() Fails with InstantiationException.
I have a servlet that would instantiate anobject, if everything worked. Unfortunately, it fails with the following exception from the Class.newInstance() method: java.lang.InstantiationException: com.wynnon.appletChannel.test.EchoingPort where EchoingPort is the class I would instantiate from. The api says this about the Exception thrown by newInstance(): InstantiationException - Thrown if this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the instantiation fails for some other reason. I printed all the modifiers for the the class, and it is not an interface, not abstract, etc. The odd thing is, if I run the instantiation code outside orion,EchoingPort instantiates properly. Questions Does orion intervene somehow in the instantiation process ? Does anybody have a clue what I'm doing wrong ?

Servlet Mapping Recursion Problem
In my web.xml I set up the servlet mapping, for a (front) servlet to handle all requests for the web app, to '/'. This works to the extent that all requests are passed to the servlet. BUT... if I do a forward to another resource from the servlet, the servlet's doGet() method is invoked recursively with no response generated until the jvm runs out of memory. The same thing happens with a url-pattern of '/*'. If the servlet itself generates html output, that works. If I map my servlet to a specific resource, like /index.html, forwarding works fine, but the servlet cant handle all requests and 'http://myhost/myapp' returns 'no directory browsing'. The url-pattern '/' seems like a valid directory specification (as per the servlet 2.2 spec, 'Servlet Mapping Techniques') and a front component, handling all requests is fundamental in the j2EE blueprints (http://java.sun.com/j2ee/blueprints/index.html, section 10.6), so my approach seems architecturally reasonable. I've looked thru the archives and found two reports of the same problem. A proposed workaround from Magnus seems to recommend explicitly mapping every request your app generates (which would make the web.xml coding difficult to maintain in a large app) pendng the delivery of 'filters', perhaps in Servlet 2.3. I dont really understand what Magnus is suggesting: PS: If you're bound to 2.2 or lower then you will not be able to use Filters, in that case you'd have to apply a more complex solution with duplicate resource roots and so on. It looks like 'no front servlets on Orion' to me, but I hope I'm wrong. I was not able to find any references to the problem on bugzilla, but I'm not very adept with its query interface. My hunch is that Orion's request dispatcher is invoked in two contexts (from a client, and from a forward) and does not distinguishbetween them when it comes to selectinga resource to respond to the client. Ifthe dispatcher ignored mapping in the forward context and just accepted the specified resource, the recursion problem would vanish and the front servlet would trap ALL client requests as per the blueprint architecture. Just a hunch, things are probably not that simple. Does anyone know if this is a problem with other webservers ? My experience with Apache was all static pages. My environment is NT4(sp6), Orion 1.4.8, IE 5.00, JDK 1.2.2. Also, if somebody is actually using the front servlet pattern and univeral mapping on Orion, and could let me know how to set it up and/or get around the recursion I'd be a happy camper. TIA, Bill.
Re: Servlet Mapping Recursion Problem
Thanks Joni, very elegant. I've started down that route (ie. having externally visible urls that are different to the internally visible urls), but hadn't thought of driving the whole thing off a configuration file. Neat. The application provider could package it with the app, leaving the front servlet truly generic. Also, the *.html servlet-mapping hides *.gif resource mapping, etc. from the servlet.. And reason number four to like this approach is: it should work on any webserver. After my previous post I discovered that recursion doesn't just happen if the '/' is mapped to your front servlet (it seems obvious now). If you map 'myUrl' to your front servlet, and then forward to 'myUrl', you also get recursion and a crash. Its been a good day, Bill. - Original Message - From: Joni Suominen [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Friday, May 11, 2001 11:48 AM Subject: Re: Servlet Mapping Recursion Problem Hi Bill! I am using a front servlet pattern with Orion. I use Struts but I suppose this approach should work in any framework. 1. The front servlet mapping in web.xml: servlet-mapping servlet-nameaction/servlet-name url-pattern*.html/url-pattern /servlet-mapping So all the requests ending to .html are processed by the front-end servlet. 2. All the valid URL's are mapped in an xml config file. The front servlet initializes its state by reading this file in a startup. An entry in this file looks like: actionpath=/faq type=org.shiftctrl.general.interaction.EmptyAction forward name=success path=/faq.jsp/ /action This means that the request http://myserver.com/faq.html is first processed by front servlet. The servlet searches its configured mapping and forwards the request. In this case it would forward the request to faq.jsp. I haven't had problems with this setup and I really like it for following reasons: 1. It is easy pipeline actions. Just configure the mapping so that its forward part points to another mapping. 2. You can hide the technology being used. Clients only see URLs which are always ending .html (so .jsps are not exposed outside, their function is only to provide the view part in MVC pattern) 3.

The url-pattern '/' seems like a valid directory specification (as per the servlet 2.2 spec, 'Servlet Mapping Techniques') and a front component, handling all requests is fundamental in the j2EE blueprints (http://java.sun.com/j2ee/blueprints/index.html, section 10.6), so my approach seems architecturally reasonable. I've looked thru the archives and found two reports of the same problem. A proposed workaround from Magnus seems to recommend explicitly mapping every request your app generates (which would make the web.xml coding difficult to maintain in a large app) pendng the delivery of 'filters', perhaps in Servlet 2.3. I dont really understand what Magnus is suggesting: PS: If you're bound to 2.2 or lower then you will not be able to use Filters, in that case you'd have to apply a more complex solution with duplicate resource roots and so on. It looks like 'no front servlets on Orion' to me, but I hope I'm wrong. I was not able to find any references to the problem on bugzilla, but I'm not very adept with its query interface. My hunch is that Orion's request dispatcher is invoked in two contexts (from a client, and from a forward) and does not distinguish between them when it comes to selecting a resource to respond to the client. If the dispatcher ignored mapping in the forward context and just accepted the specified resource, the recursion problem would vanish and the front servlet would trap ALL client requests as per the blueprint architecture. Just a hunch, things are probably not that simple. Does anyone know if this is a problem with other webservers ? My experience with Apache was all static pages. My environment is NT4(sp6), Orion 1.4.8, IE 5.00, JDK 1.2.2. Also, if somebody is actually using the front servlet pattern and univeral mapping on Orion, and could let me know how
Re: Basic Authentication
I 've learned how to get basic authentication going, given Brian's suggestion, and a little more trial and error. Things that I would like to add to the authentication-primer at jollem (if I had the time this week) include: 1. You need the login-config tag in web.xml 2. you need the security-role-mapping tag in orion-application.xml. 3. I also needed to understand the scope of the url-pattern '/' entered in web.xml. It protects everything but the root, to protect that too you need to enter '*' as the url-pattern. I suppose 'x' means directory x, and 'x\' means the content of directory x. In a url-pattern, '*' seems to mean 'whatever the root directory is'. Given the above and appropriate group and user defns in orion\config\principals things work OK. I've attached a zip of my test-app's application's xml files.

Re: common practice for configuring orion app/web-site
I prefer to do lots of little apps tied togoether by the data they share in an enterprise database (I'll admit the term enterprise database is optimistic but I've just done two years at a client who started his IT shop from scratch, so I'm spoiled). The many apps to one db patttern was practical, even pre-j2ee, and I find the the servlet/jsp/jdbc paradigm conceptually covers that pattern and allows better implementation patterns (eg front servlet) in the middle tier. I'm just getting into ejbs and expect to share them between web-tier apps. Discussion on this list indicates that it can be done, using orion. Thus, in the ideal world, I expect to develop lots of little apps using fewer ejbs against very few enterprise databases. Unless there are technology constraints I dont know about, I will DEFINITELY NOT go down the path of one humongous app. That way lies maintenance madness. Much better to learn techniques for efficiently sharing extensions, ejbs, database, etc. in a deliberately modular way.

I guess the auto-unpack fails because the file isn't totally

The simple work-around is to copy it to a temporary filename and
then rename it to the real .ear.
See below for a better (IMHO) solution for deploy an application.

Thers is no need to use the Orion's "-admin" option to deploy an
application. I usually rely on the auto-deploy feature of Orion
which trigger timestamp changes on the .ear file.
A remote deployment is easy if you use the "rsync" utility
(http://rsync.samba.org) that provides fast incremental file transfer
over the network.
Rsync mangle the file name until the trasfer is complete so there is
non need to perform an additional rename of the file or a restart
of the server.
For better security you can tunnel the rsync traffic over an encrypted
channel with "ssh" (http://openssh.org).
This is the ant target I use for remote (or local) deployment:
target name="deploy" depends="all"
exec failonerror="true" executable="rsync"
arg line="-azv -e ssh" /
arg value="${app-ear.file}" /
arg value="${deploy.app-ear.dir}" /
/exec
/target
Hope this helps.

WAS RE: productive comment. Ok, I feel it's time for me to step in here as one of the 'Joe Co.' people. Firstly, everyone calm down. As Hani said yesterday, every few weeks this whole "Orion support sucks, my boss won't buy Orion without support, I'm having a whinge" thread starts up again. Calm down and read the archives people ;) THE SITUATION: With regard to the future of OrionSupport, here are the things I _know_ are currently happening: - As far as I know it, Joe is on holidays which is probably why he's not answering his email - he hasn't been on IRC for about a week. Everyone just calm down ;) - The domain IS owned by IronFlare / Orion. As far as I know this was done by the previous owners so that it would always be an Orion support site. I have no problems with this at all, the guys have given us free reign over the content / production of the site. - The site IS down now, I'm not sure why. It seems to me Joe's machine has fallen over but we'll know when we get back. Meanwhile there is an archive of all content up to March 18th kindly hosted at www.theculprit.com - There ARE moves in progress to upgrade the site. As Hani said in a previous email it currently runs on lots of OpenSymphony technologies ( http://www.opensymphony.com - see gratuitous-OpenSymphony-plug at the end of this email) like SiteMesh, OSCache and Clickstream. I'm in the process of upgrading it to use OSContent so we'll have a fully fledged CMS with community features to boot. This will take a week or two at the least. THE PROBLEM: - The above measures are purely technical and won't help the Orion community in and of themselves. OrionSupport's biggest problem so far has been GETTING PEOPLE TO CONTRIBUTE. JoeO says this better than I could in his rant http://www.theculprit.com/www.orionsupport.com/articles/vision-2.html . BASICALLY if noone contributes the site will continue to move ahead at it's trickling pace. - HOWEVER if lots of people take 5 minutes to note down the problem they just solved, the bug they worked around, their expertise on a particular area, their knowledge of using Orion with software X - we can really produce a very useful support resource very fast indeed. Keep reading for how you can help. THE SOLUTION: I suggest we move discussion of this off the list (the last 48 hours has driven me nuts with the lack of Orion questions and the volume of "me too, Orion support sucks, I'm complaining and not doing anything about it" emails. If you don't like it, join those who are trying to do something about it! I've set up an egroup (still can't bring myself to call it a Yahoo! Group yet) for discussing it here http://groups.yahoo.com/group/orionsupport The manifesto of the group is: "A group for the authors and users of OrionSupport ( http://www.orionsupport.com ) to discuss content needed, moves ahead etc. NOTE: This is not a group for people looking for support for Orion. See http://www.orionserver.com for that" I hope you'll all join up and that together we can make OrionSupport an even better resource for the community. -mike gratuitous-OpenSymphony-plug If anyone else has some spare time and wants to help out the most advanced Open Source J2EE project out there, OpenSymphony is it ;) Check it out at http://www.opensymphony.com , help by downloading, using, testing, developing, documenting or even just suggesting ideas - let me know where you can help!

Re: configuring jndi
I'm interested. What was the problem ? Bill. - Original Message - From: "Christy Nicklas" [EMAIL PROTECTED] To: "Orion-Interest" [EMAIL PROTECTED] Sent: Thursday, April 05, 2001 2:50 PM Subject: RE: configuring jndi Actually, you can ignore my earlier message, as I found the immediate problem, although a pointer on how to configure jndi in general would probably still be helpful. --Christy
Localhost and IP Yield Different Pages
I've just wasted an hour or so debugging a non-existent problem with my default-app configuration that was caused by IE's page cache ! It had locked onto a page for http://localhostwhich it presented instead of the page I'd confugured. Short of persuading MS to get out of the html page-caching business (and the filesystem caching busines while they're at it), does anybody know how to flush all of IE's 'performance-boosting' (hah!), caches ?
Re: admin.jar deploy failed after autoupdate
I was doing autoupdate to a 1.3.8 installation - after re-installing at the 1.4.5 level the problem is gone. - Original Message - From: Bill Winspur To: Orion-Interest Sent: Monday, March 26, 2001 12:14 PM Subject: admin.jar deploy failed after autoupdate I've been using admin.jar to deploy my appsfor several months, but it failed after I did an autoupdate on my server (about Mar 13th). The failuremessages areendless repetition of: at com.evermind.server.ApplicationServerSystemProperties.getProperty(JAX)at java.lang.System.getProperty(System.java:562)at com.evermind.server.Application.w8(JAX)at com.evermind.server.ApplicationServerSystemProperties.getProperty(JAX)at java.lang.System.getProperty(System.java:562)at com.evermind.server.Application.w8(JAX)at com.evermind.server.ApplicationServerSystemProperties.getProperty(JAX)at java.lang.System.getProperty(System.java:562)at com.evermind.server.Application.w8(JAX) In the interim, I've been shutting down the server, replacing the ear file in orion/applications and restarting, which works fine, except that I have to shutdown and restart. Incidentally, an advantage of the approach is that it avoids admin.jar's habit of renaming previous deployment (by prepending '_' to the app name) instead of replacing it.
