Setup Advice Needed: dev vs. test vs. production
I have some web services running on tomcat and I am trying to figure out the best way to have 1 tomcat instance running all 3 environments. So the tomcat would run dev, test, and production on one tomcat instance. I don't want to install 3 instances of tomcat on the customers machine for running the different environments. I guess the way I would like it to work is to have the web services have the same name regardless of the environment. The easy way to think about it is to have each environment running on a different port. Is this possible? Or would it be easier to have a virtual host? For now I just need to be pointed in the correct direction on what is the best way to handle this situation with tomcat. If you do have a suggestion and know how to set it up then please pass it along. Thanks, Susan === Susan G.

RE: Setup Advice Needed: dev vs. test vs. production
I hear you. But in our environment it just isn't feasible to install three different tomcats on the customer's system. So I was trying to come up with a way to do this without having to rename a bunch of stuff. If it was running on a different virtual host for each environment or different ports. Can Tomcat be setup so 3 VM instances are ran under one tomcat installation? With the constraint that only one tomcat can be installed on the system what is the best way to run 3 separate environments?

I strongly suggest you rethink that, and use at least three separate Tomcat instances. Trying to run everything in one instance puts production at a severe risk of failure should anything in the dev or test environment have a problem (e.g., infinite loop, heap overflow). Given the extremely low cost of hardware (or VMs) these days, I'd have the test and prod systems on different boxes or VMs, and let each developer run their own Tomcat instance on their own workstation. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Setup Advice Needed: dev vs. test vs. production
You are preaching to the choir here about the multiple installs. But I can't. This is running on an AS400. And the clients are very particular on what you can install. So I am stuck. FYI: The dev, test, and production is for my software not Tomcat. So I have 3 or more versions of the software that I have to support. I want to have 1 tomcat installation will all of the versions on it at my customer site. Actual development happens on my laptop but sometimes I have versions that the customer has to play with and give feedback on that aren't ready for testing. This I would install under dev, then others that are actually in the testing phase and then finally production. On my laptop I have multiple tomcat installations but I don't have that luxury on the customer's as400. So my thought process is I will have to change my software that communicates with the web services so that it calls different web services depending on dev, test, or production. However I don't want to have to do this. It would be better if I could just change the port. I don't know if a virtual host would give me anything or not.

Running separate Tomcats for each avoids that issue. Can Tomcat be setup so 3 VM instances are ran under one tomcat installation? Assuming you mean JVM, not VM, you can read RUNNING.txt in the Tomcat home directory to see how multiple Tomcat instances can be run with one copy of the Tomcat jar files. But I'm not sure what you think you're gaining by doing so. Having separate installations and running instances lets you test on a new Tomcat version before committing it to production. With the constraint that only one tomcat can be installed on the system what is the best way to run 3 separate environments? Get rid of the constraint; it's nonsensical. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Serving images from classes directory
Andre,
Thanks. I know serving images from the classes directory is not the best
way to do stuff. But from a maintenance/source control stand point it sure
would make things a lot easier if I didn't have to pick and choose what
directories to move when deploying on the users machines. Because the tool
app deploys the web apps that it builds as classes under it's own classes
directory, I have to move all of my custom scripts and graphics to another
location in order to use them. As I said it would make my life much easier
if everything was in one spot. That way I could package everything easier
and maintain with subversion easier. This is a windows box so I can't just
put links in the other area. I actually have to move or copy the pieces.
Having multiple copies of the same objects is not a fix because they have to
be kept up to date.
I knew when I posted the first request that it was strange. But sometimes
we have to take that square peg and hammer it into the round whole. So if
anyone has any ideas (I will take a look at your rewriting url stuff.
Thanks!) how this can be done then I am all ears. If you just want to slam
me for doing something different then don't bother.
Thanks,
Susan

Susan,
have a look at this :
http://tuckey.org/urlrewrite/
This is a servlet filter, which kind of wraps your webapp,
intercepting all calls before they reach your webapp.
On the way, it allows you to modify the request URL (for instance), to
for example to redirect the call to some simple servlet which would just
return said image.
Or maybe - my knowledge is too limited to really tell - arrange for
these calls to be served by Tomcat's default webapp, which serves static
items.
Note that I am not in all this taking a stance on whether what you want
to do is fundamentally a good idea, which from the previous expert
testimonies here, it seems it is not.
Also, the reason that said experts object so strenuously to what you
want to do, is not that they just personally don't like it for some
reason of elegance or so. Their main objection probably has to do with
the security of your website. Mixing code (which you do not want to
disclose to just about anyone) with static objects (which you want to
disclose of course) is probably the best way to introduce huge holes in
whatever security scheme your site would otherwise have.
So the experts are telling you don't do that, because in their expert
and considerate opinion, they don't feel that they should help you do by
yourself something that will definitely put your site at risk.

If the images are physical images in the classes directory - you have a
few options.
1) At build time - move (or copy) the files from the classes directory
to somewhere more sane that the default servlet can access
2) Write a filter the detects these images that live in the classes dir,
and then forwards to the images. (You need to be careful with this one)

this would be easy. You know a servlet mapping in the web.xml file that
would allow me to just map the directory/file type and I could just put
that
in my html. Since I can't use jsp everywhere I need the images. Again I
am
tied into their system and they have stuff in html files that they create.
I edit the html template files they have to add my images and javascript.
I use their environment to create/edit/build the web application.
Underneath
I have tied in netBeans the best I can so I can debug their stuff. But
that
has issues too.
If you can edit the template files, can't you include images in the same
place as the templates?

If the images are physical images in the classes directory - you have a
few options.
1) At build time - move (or copy) the files from the classes directory
to somewhere more sane that the default servlet can access
2) Write a filter the detects these images that live in the classes dir,
and then forwards to the images. (You need to be careful with this one)
For # 2 - it would look something like this:
doFilter(...) {
String p = request.getServletPath();
if (p.matches(/magic_prefix/[\\w]+\\.gif$)) {
String np = request.getServletPath().replaceFirst(.+/, );
request.getRequestDispatcher(/WEB-INF/class/more/cowbell/ + np)
.forward(request, response);
} else {
chain.doFilter(...);
}
}

RE: Serving images from classes directory
I started with the authors of the tool app and they said it was a tomcat
limitation. Basically can't be done. So I figured I would try the list
before I took their word for it.
Yes, I use the tool to modify the template files. But that is basically
just editing html using the tool. When the tool app builds my app it copies
everything into the classes directory. So that everything looks like one
big Java class under the tool app. So my thought is that my images and
javascripts should go in here so I can have everything together and make
maintenance easier. I check everything the tool app builds into subversion
so I can have some source control.
Thanks,
Susan

For reference then, we'll call the first one the 'tool app'.
So are you actually editing the template files yourself, or are you
using the tool app to edit the template files?
Where in your app do the modified template files end up, and are they
copied individually?
The thought also occurs that the authors of the tool app might be the
people you really want to be talking to about this.

Tomcat 6 Manager
I am trying to use the deployment of a host directory under the tomcat manager. The context path that I want to use is /webapp/bfc. However whenever I try to deploy the directory it gives me an invalid context path and it fails to deploy. What should I put in the context path to have it deploy to /webapps/bfc?

RE: Tomcat 6 Manager
When you go into the Tomcat Manager you get a list of running web applications. Then the next section lets you deploy a host directory or local WAR file. It asks for the following information: Context Path (optional): [I have found this is not optional] XML Configuration file URL: [This appears to be optional] WAR or Directory URL:[Here I enter my host directory path] I don't have anything in my server.xml. Just a generic tomcat 6 install. When I enter anything in the Context path that has a 2 tier specification .i.e. xyz/abc I get an error when I try to deploy the host directory. I have been able to deploy a different directory using just xyx. So basically if I have a unix directory called /mywebapps/xyz that has a web application in it. And I want to deploy it using the Tomcat Manager what would I put in for the Context Path. I know that the WAR or Directory should be /mywebapps/xyz. I want the context path to be xyz/abc. However if I put that in the deployment fails. Does this explain it a little better?

What should I put in the context path to have it deploy to /webapps/bfc? webapps is usually the host's appBase. I am a little confused. A few questions: - what is the full path to your Tomcat installation? - what is your host configuration in server.xml? - what is the full path to the directory you want to deploy? - what url do you want to use to access this web app?

redirect port 80 to application server
I am not sure if this is the right list for this. But I have an Apache HTTP server front end and I want to redirect port 80 so that it goes to port 8080. Thanks, Susan === Susan G.

RE: redirect port 80 to application server
I have to have the Apache HTTP in front. Don't want it there but it is required by the customer. So they type in http://myserver/webapp and expect it to go to the application server. I say just use the port http://myserver:8080/webapp and you will get to the application server. They say we don't want to type in the port just make 80 redirect to the application server port. So, I am here trying to figure out the easiest way to redirect all traffic from 80 to 8080 and still have the apache running in front. Should I use remote proxies?

System requirements for running Apache Tomcat on Windows Box
I am trying to put together some system requires for running Apache HTTP Server and Tomcat on windows machines. I have looked all over but I can't seem to find a minimum system specification for windows. I want to run tomcat 6.0 and I need CPU, Hard Drive Space, Memory and anything else that will tell the customer what the need. I would like to know the minimum, medium, ideal system specifications for windows. If anyone know where I can find this information or has these specs please let me know. Thanks, Susan === Susan G.
