RE: Setting Up Tomcat for Multiple Users
I read something on the $CATALINA BASE but don't know how to deploy that. Would be grateful for any help given I am no expert, but I believe $CATALINA BASE would only be helpful if everyone had his or her own Tomcat server each of which pulled classes and other files from a base install. That's most useful for clustering. Netbeans is a free IDE from Sun that comes with it's own internal Tomcat server bundled inside the IDE. Consider incorporating it in your class. I am very impressed with it's debugger, and each student might benefit from breaking and fixing the server.xml. Besides, at some point everyone in Javaland needs to deal with an IDE. If you insist on having a central server, then you want something similar to apache's public_html. http://httpd.apache.org/docs-2.0/howto/public_html.html I don't know if Tomcat alone has that functionality, but you might get what you need by Apache running tomcat as a module.

RE: Why JBoss (and Tomcat)?
Thanks for the great reply. You are mixing several different things: I agree. Sorry to be so thick, everyone. I hope I am not too far off topic with this conversation thread, but I simply don't understand how JBoss differs from the J2EE SDK. - J2EE is a spec that consists of several technologies. Most of these technologies can stand for them selves and be used without the others. (Some of them are related or even dependend to some extend) Sure. It's a spec. That I understand. - JBOSS is an implementation of that spec. So they say. So, why heck would I want it if I have the J2EE SDK and other fun Sun dowloads? Doesn't Sun offer *thee original* implementation of that spec alerady? Does JBoss rely on the J2EE SDK? Does it try to replace it? Is it a bunch of Sun downloads repakcaged in one big .tar? Is JBoss really an App Server? Does it run it's own asynchronous threads outside of the standard Tomcat threads? It doesn't implement all technologies from scratch but integrates other projects to implement some of them. (Like tomcat to implement Servlets and JSP, or use JavaMail and JDBC from sun) It sounds to me like JBoss is simply repackaging Tomcat, Ant, and some other Jakarta stuff along with the Sun J2EE SDK and some common jar files like Javamail and JDBC. Is so, then it also sounds to me like all they're trying to do is save developers a few downloads so that they can sell some expensive centralized documentation. Not a bad idea, but it's not for me because I already have all of that installed. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Problem with Excel and Word Documents
While downloading/viewing a file from a jsp page, there are no problems encountered by IE. But, when the same is opened on Netscape 7.0 (and up), the file is opened up in the same window and all the data is improperly rendered because NS cannot interpret the file properly. Are you familiar with MIME types? If not, then Google MIME types. According to the HTTP spec, the HTTP Accept header specifies the media MIME types. Try looking up the res.setContentType() function to set that header value for your HttpServletResponse. Before you send some response res, I believe you should specify the content type with that function. Netscape is probably to spec. Windows cheats by parsing the file extension (.txt, .xls, .doc) to help you out. I believe there are also MIME !ELEMENTS that can be added to web.xml to achieve this as well within Tomcat. regards, MPC - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Why JBoss (and Tomcat)?
(J2EE SDK the is not intended as a tool for production) Thanks for the post. Can you please clarify? Are you saying that the J2EE SDK is not production quality while JBoss is? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Why JBoss (and Tomcat)?
Perhaps this will help you decide which application server to use. http://www.theserverside.com/reviews/matrix.jsp This Matrix is excellent. Thanks, James. I noticed that J2EE x Tomcat was not checked off? For my project, I will need servlets with J2EE, JMS etc. Why can't I simply use Tomcat along with the J2EE SDK? It seems to me that I might want to blow away my Tomcat install and unpack JBoss (with Tomcat). MPC - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: (OT) Why JBoss (and Tomcat)?
Sun want's to sell their Sun ONE software, so the licence for the free J2EE SDK is restricted. (For internal use and development) (But this is getting quite off topic for this list) Thanks for the reply. Now it's clear to me. As James stated in his last email Sun's implementation also uses Tomcat as does JBoss. So many people are using Tomcat with J2EE as part of a greater bundle, that I bet it's a common newbie assumption that Tomcat alone supports J2EE. Clearly it does not. The fact that the Sun J2EE is a reference implementation and not meant for production came as another bonus surprise - directly relevant to my bogus J2EE install anyway. I think that all this information is on-topic and very important. Many people who are new to Tomcat grab the .tar installer from the Jakarta site, and come to this list for immeadiate help. I think it's a great thing for the archives to show that if you want servlets with full J2EE functionality then you had best stop that Tomcat install and download the JBoss installer (or some competing bundled product) instead, and yet don't worry. You'll still be using Tomcat in the end. Sure, all this information is on the web, but I believe it's purposefully convoluted because everyone's trying to make a buck. Sun wants to give and sell the SDK. Tomcat is free but rebundled with commercial products (and semi-commercial products with deliberately little documentation - aka JBoss). As if it all wasn't confusing enough. But thanks to you all on the list, now I know the score.

HelloWorld embedded applet not being served
I'm having trouble serving up a fairly simple embedded applet from the O'reilly Servlet Programming tutorials. Tomcat can't seem to find the applet that I request from loginpage.html using this line of HTML. applet CODE=DaytimeApplet CODEBASE=/ WIDTH=300 HEIGHT=180/applet The HTML page is served just fine, but both IE and Netscape seem to bring up an empty applet. I see the Sun logo in the browser so I am assuming it's a Tomcat config issue and not a local client problem. Does Tomcat expect applets to reside next to servlets in the WEB-INF/classes directory? I can't seem to find much documentation and Tomcat and the applet tag. This was the web.xml IN used for the example above. It was my best guess. I scanned the DTD but didn't find the relevant ELEMENTS or ATTRIBUTES. web-app servlet servlet-nameDT/servlet-name servlet-classDaytimeApplet/servlet-class /servlet servlet-mapping servlet-nameDT/servlet-name url-pattern/DaytimeApplet/url-pattern /servlet-mapping /web-app Tomcat version 4.1.27 gave me this output with debug=99 2003-12-22 13:24:52 StandardHost[localhost]: Mapping request URI '/loginpage.html' 2003-12-22 13:24:52 StandardHost[localhost]: Trying the longest context path prefix 2003-12-22 13:24:52 StandardHost[localhost]: Mapped to context '' 2003-12-22 13:24:52 StandardHost[localhost]: Mapping request URI '/DaytimeApplet.class' 2003-12-22 13:24:52 StandardHost[localhost]: Trying the longest context path prefix 2003-12-22 13:24:52 StandardHost[localhost]: Mapped to context '' 2003-12-22 13:24:52 StandardHost[localhost]: Mapping request URI '/DaytimeApplet.class' 2003-12-22 13:24:52 StandardHost[localhost]: Trying the longest context path prefix 2003-12-22 13:24:52 StandardHost[localhost]: Mapped to context '' 2003-12-22 13:24:57 HostConfig[localhost]: Deploying discovered web applications TIA, Mike C - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Why JBoss (and Tomcat)?
This might seem like an embarrassing question (or a poor post for the Tomcat-user list), but why would a developer want to download JBoss with Tomcat bundled instead of Tomcat alone? Does the Jakarta project have a competing open-source appsever product? I understand why someone would need an application server for Apache, but isn't Tomcat prepared to track sessions, manage DB connection objects with JDBC, etc? Does JBoss provide standard code for Shopping Carts? What does it offer that Tomcat does not? I'm sure there is a good reason for App Servers. If someone can clue me in as to the limits of Tomcat and the common uses of an App Server, I would appreciate it. The only decent Documentation for JBoss is for sale. Their site was not very informative. I don't know if I trust their POV anyway. In the mealtime, I've got the JBoss installer tar to try out and no manual.

RE: Why JBoss (and Tomcat)?
Thanks for the reply. Tomcat is a servlet (and jsp) container. Thats it, nothing else. Zippo. Understood. Although Tomcat seems to be more robust than Apache in tracking sessions and saving state, which is what App Servers did in the past. JBoss is a full J2EE server which offers all the J2EE services To help drive the point home, can someone please give a few more examples of J2EE services? I swear, I've looked through all the Sun App server and Jboss literature and there is very little about what one might do with them. Finally, the Jakarta project seems so robust, why is there no Jakarta equivalent? Or is there?

RE: Why JBoss (and Tomcat)?
Thanks again for the reply, Tim. As you can tell, I am a little confused although it's becoming somewhat more clear. J2EE includes JMS, EJB, and a bunch of other acronyms. java.sun.com should have a whitepaper about j2ee and everything it can do. I think I can imagine that whitepaper. This might be the source of my confusion: I was under the impression that JMS, EJBs, etc. were supplied by the J2EE SDK. If so, what does JBoss give me on top of that SDK? Let's take JMS as an example: I remember compiling and running Java Messenger Service code examples as stand alone Java programs (without JBoss). I just assumed that I was able and expected to write servlets to make use of the robust JMS Development Kit. Was I wrong? If not, then what exactly would JBoss offer on top of the J2EE SDK and Tomcat? Does JBoss (WebShere, BEA Weblogic) offer some kind of JMS Servlet libraries on top of the already robust J2EE sdk? Do they simply give persistence? I can't seem to find a direct answer to that question. There is an apache project called Geronimo but it is in its infancy (i think). I can imagine that the existence of JBoss would steal some of Geronimo's thunder despite the cool project name.

RE: Start and stop server
There is a Startup and Shutdown batch scripts in your Tomcat's bin directory. I also remember that Tomcat 4 also used to be a Windows Service, for stopping, starting, and running on startup.
