Harbor is really something we did for ourselves, for internal use. Packaging it and putting it out there is only 1 week old its brand new, and the site does say use with caution. The momentum for this is actually coming from friends. When they saw us popping applications out of browsers just using Tomcat, they got more excited than we did. Dont think I've worked so hard in my life... spending hours showing people how to ban their supercan, which now seems to be the name for the informal course. So thats why we doing this, packaging it, giving it a site, mailing list etc... tired of visitors :) The 1 day old Mailing list can be found at http://coolharbor.100free.com/mailing_list.htm I'm also trying to get samples of things like mailing and dB pools up on to the site please be patient, its coming and its got a mailing list now so we dont have to bug the Tomcat guys anymore I thank Apache again. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I think its a new way of looking at application servers, it feels like a discovery to me, but then who knows maybe there is something out there like this, I dont know, all I do know is that when we drop this servlet into Tomcat, we run POJO applications over the wire as if they were right their on the client machine, the same applications that will also run standalone on the machine. Its so different that I really struggled to find the relevent theory behind this technology, I think I'm close, but any pointers or corrections would be much appreciated there as well. Just one question, what do you need tomcat for? Remove the tomcat from your app server, add rmi, corba, and, if you really wish, a http connector (which could be tomcat or a small http listener with xml parser) , and yeah, you are back to the good old days... Well, I thought about that, but not quite in the same way, I thought about taking it down to the Apache native socket level, but decided TC is a much better solution. Harbor doesnt use RMI, and it doesnt use SOAP, all the protocols for Harbor, the required serialization, the Java reflection, everything was re-done. Crazy Huh ;) I wanted a pure fast binary HTTP based protocol, and there wasnt a complete protocol out there that could do what I needed. RMI I felt is a little too primative for what I needed, but as you know, the real problem is that its not HTTP driven, and as soon as firewalls come into play, guess what, you probably have to use tomcat and a servlet to tunnel through the firewall, nah! its old technology, ok for EJB servers ;) Then there is the whole concept of registries, which RMI and just about every other SUN service specification, EJB, SOAP, all have some place the thing has to be registered. In this context I felt that it was also superfluous. Harbor addresses in the same way a web site does. My application is at http://harbor etc, which is really nice and easy for users to understand. An EJB client is really a completely separate thing to the EJB server implementation and needs a discovery mechanism. Harbor houses full applications, so the client side knows about its server side, its just very different. In coding terms it comes down to, I want to talk to that Harbor I want to run that thing Go! It literally comes down to that code... have a look at the examples on the site. Probably the easiest RMI available. So, to answer your question, the protocol is especially made to be as easy to set up and run as a web site, and runs on port 80, just like a web site does, it makes it very easy... you never going to see a user asking how to get the RMI working through their firewall etc. So to answer your question, Tomcat is essentially a nifty container with great HTTP communications, thats what this technology needs, why re-invent a terrific wheel. The rest is perspective if one looks at TC as nifty container with great communications, why does an application server do its own thing, and incorporate TC as an add on the reason I think is because they do exactly that, use old RMI, and it sees web technology as an addon. I decided that there is no better communication protocol than the web based ones (at binary level), why mess with that, make the application server use it. As for SOAP, well any protocol with all that machinery is bound to be slow and pathetic, it links to non java products, ok thats nice. Its just philosophy... do you think an servlet container should be a layer ontop of an application server, or the other way around (this makes more sense to me). As for not having a servlet container at all, I wonder how other application servers are doing their HTML admin consoles... When I'm working on a site and suddenly realise that an application server may come in handy, its really nice not even having to consider moving away from TC, I just keep going... Hope that answers the question Harbor is new, need to give us a little time to start bench marking etc, but I have a feeling when its delivering full accounting programs and powerful games to users on the web it wont be seen as the relic container ;)... not even sure a comparison will be possible. For example EJB has

Could you please tell us why is this specific to Tomcat? Sorry I live on the other side of the world, I was sleeping ;) In theory, its not, its a servlet and thus should run on any servlet container, but its one hell of a servlet, and internally there is some serious class loader stuff going on. A little like having Tomcat run inside Tomcat, if that makes sense. It also uses TC's security setup and thats preconfigured in WEB.xml and I imagine a little different on other containers, so users may find that a hassle factor. It's certified for Tomcat really just because thats the only servlet container we use... and my way of giving back, yes I do want new comers to come to the TC mailing lists. Or let me say it this way, I could have taken the tomcat code and combined it with this servlet internally and then given it the name of some fish, but I wanted all credits to come back to TC for the servlet container... so maybe its just misguided loyalty ;) But there is a technical reason as well, when class loaders run inside class loaders, or class loaders run inside another container, it really brings out issues with the underlying class loaders inside a container. So I feel it should be tested carefully on any other servlet container. I havnt tested on other servlet containers, because I think half of them run on TC code anyway, not much of a test, but if you want to see a container fail, try make WebStart use an RMI program, or a program that has its own class loaders... it will likely fail. When testing I actually ran TC from the source and traced into TC just to make sure classloaders were doing the right thing, they do, fortunately. So there is a degree of caution, and a whole lot of loyalty ;) By all means if you use something else, try it but I do have a feeling the security side may need a rework of the configuration, and may not work at all because it twists normal web security to protect classes, so that one can protect access to their applications.

What problems does it solve? How is that specific to Tomcat, instead of just any servlet container? Greetings, Lilianne E. Blaze Johnny Kewl wrote: I'd like to show you guys something that I think may blow your minds. Firstly let me just say that I call myself a hobbyist, dont consider myself in the same league as the guru's that work on Tomcat and Apache, but I do spend an enormous amount of time playing with technology. One can almost measure how much I like a technology by how much time I stay in the mailing lists, on Postgresql I think it was 3 months, and I really like that product, on Tomcat it must be close to a year and still counting, what a fantastic product. In our office Tomcat is now officially the delivery mechanism for everything. First I was impressed with Tomcats web abilities, then more and more with its container ability, we discovered that it can run any code, and even if it wasnt intended for the web, we started sticking applications into Tomcat anywaythat idea has now come a long way. I call it a POJO Application server, I've mentioned before that we actually popping full java applications out of browsers, but then it was very much something only I could use, messy libraries etc. What I've done now is (try) make a more professional package, and it would be really nice if the guru's just have a little read about this unbelievable servlet, and let me know what you think, if just to see how someone is using your Tomcat, in a very unusual way. As you will see, I dont like EJB containers, but I love Tomcat, and it was almost inevitable that this would happen. All I will say is that this is no ordinary application server... not unless I missed something and you can also just drop a POJO application into the others and make it remoteable. I think its a new way of looking at application servers, it feels like a discovery to me, but then who knows maybe there is something out there like this, I dont know, all I do know is that when we drop this servlet into Tomcat, we run POJO applications over the wire as if they were right their on the client machine, the same applications that will also run standalone on the machine. Its so different that I really struggled to find the relevent theory behind this technology, I think I'm close, but any pointers or corrections would be much appreciated there as well. Anyway, would just like to thank all the Tomcat'ers that have helped me out, people like Chuck, Bill, Christopher, Leon, David, Mark, Mladen... and if I forgotten you, sorry, so many, it really is the best mailing list on the web
