help installing
I am new to the list and Tomcat. I know this has probably been answered,
but I am having trouble finding it in the archives. Is there an
installation guide that makes sense some where?
I would like some thing with a definition of files, what to edit, what
works, how to install from source. I find the documentation on
jakarta.apache.org/tomcat to be confusing. Any help is appreciated.
Thanks in advance,
J. Case

Thank you, thank you, thank you!
This is exactly what I was hoping for. Something simple and straight
forward!

Re: Accessing images through FrontController Servlet
Posted by Dakota Jack <da...@gmail.com>.
You are right that a call for an image, or css for that matter, is
another call to the server. And, this call is really not anything
special, except that it returns a stream. If you want to get a
response from a URL, then you have to follow the rules in doing this.
If you instead want to get a response from a protocol, like using a
servlet, then you have different rules. There is nothing really
magical going on. Why are you using this "init" business?

Re: Accessing images through FrontController Servlet

Thanks Robert,
Hard-coding the images works fine, but I'm leery of this,
as they will of course all need to be changed when the app
goes up on a public server; changes could be localized, but...
Is there really no way to declare <img> calls in the web-app
that would allow images to use relative path names?
The init-param 'imgURL' sounds like it should allow this,
but I'm not familiar with it.
Thanks for your suggestion, which gets things moving again.
Thanks too for the pointer to Ethereal; looks like a useful tool.
Best,
-BC

Re: Accessing images through FrontController Servlet
Posted by "Robert r. Sanders" <ro...@ipov.net>.
Do you have any logs of what's going on? Also, make sure the pages are
using the <c:url /> tag (or equivalent), as the image paths need to be
relative to the url that the client browser see - should be able to hard
code the path to be /ntrr/images/whatever.jpg
To check for bad paths first view page source from your browser, then
you can get the image urls and see if they map to the correct path.
There are also some nice tools that you can run to see what's going on,
for instance the "Live Headers" extension for Firefox, or Ethereal for a
more general solution

Accessing images through FrontController Servlet
Posted by William BC Crandall <bc...@earthlink.net>.
Hello,
I'm starting a new project, using a FrontController servlet
(http://java.sun.com/j2ee/patterns/FrontController.html),
and am unable to access image files.
My understanding is that each <img> invokes another call
to the server/servlet, which, due to the mapping in web.xml,
is channeled through the controller servlet, which rejects
the call because it does not point to a sub-servlet.
How can I access images in webapps/ntrr/images/ ?
My web.xml:
<web-app>
<servlet>
<servlet-name>
controller
</servlet-name>
<servlet-class>
org.ntrr.core.ControlServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>
controller
</servlet-name>
<url-pattern>
/*
</url-pattern>
</servlet-mapping>
</web-app>
I have tried, without success, adding:
<init-param>
<param-name>imageUrl</param-name>
<param-value>http://localhost:8080/ntrr/images/</param-value>
</init-param>
The files in webapps/ntrr/images/ ARE accessible from
webapps/ntrr/css/ntrr.css, when called as background
page images, for example.
Any suggestions welcomed.
Thanks,
-BC

If you're installig on a linux machine, we have a brief guide on setting up
Tomcat for our virtual linux machine service at
http://www.mythic-beasts.com/support/topic_vds_java.html
This is designed for low volume simple usage, everything is done directly by
Tomcat and there is no challenges with connectors and apache for example.
We're in the process of finalising our virtual hosting guide.
Hope this helps,
Pete Stevens

Thanks to all for responding. The information I received was much
clearer and easier to understand then the apache site!

Welcome. :)
I actually had to scratch my head thinking about if there was such a
guide and finally had to do a google to find
http://www.coreservlets.com/Apache-Tomcat-Tutorial/ That seems like
just what you're after. Although I don't know what they were thinking
with all that pink and magenta on the page...
