Re: quick question when getting started
Hi Stephen, You've been tricked by the web.xml. The JSP's are pre-compiled to servlets and a mapping for the URL /index.jsp to this servlet has been inserted into web.xml. If you delete the servlet mapping in the web.xml, everything should be as normal, and your changes will be visible. (this caught me out the first time too... ;-) ) Michiel Stephen Charles Huey wrote: I'm upgrading from Tomcat 4 to 5 and I just installed Tomcat 5 on a dev machine to play with it, and I know a couple things are organized a bit differently, but the provided index page is weirding me out.

Re: quick question
Hi Steven, You should be able to if your URI directive is something like, [uri:localhost/*.jsp]. The other thing that you need to do is set up the proper context for the JSP, so if you want to place them in /home/apache, you'll need to add the proper context directive in your server.xml file.

RE: Quick Question
IMO, it seems like a bad idea to me to tie your bean
code to a servlet context unless you REALLY need to.
To me, a better way would be to put the file in a
directory under classes, and use the classloader of
the current thread to get to the file.
This way, you do not need servlet.jar to use your bean
if you every decide to use it outside of a servlet.
This is a very simple process. Here is an example:
private InputStream getFile(String name){
return Thread.
currentThread().
getContextClassLoader().
getResourceAsStream(name);
}
To read a properties file classes/myprops.properties
for instance, you just do this:
Properties p = new Properties();
p.load(getFile(myprops.properties));

Howdy,

doesn't work. Is there something else along the same lines that will?
How's about:
URL destinationURL = ...getResource(...);
URLConnection destinationConnection = URL.openConnection();
destinationConnection.setDoOutput();
OutputStream outputStream = destinationConnection.getOutputStream();
...
You are not guaranteed this will always work across containers. I don't
think the spec says the container *has* to give you write permission to
URLs obtained this way.

RE: Quick Question
It is little more work to get read/write access, but the getResource()
method will give you a URL object.
You can then use URL.getProtocol() to see if it is coming from a file or
something else (a jar or even http, if you use the URLClassLoader), then
use the URL.getFile() if it was a file to get the path to the file.
Might be a good idea if you want to do that to create a
class that makes this more abstract so you have a single API to work
with instead of trying to remember all the ClassLoader/URL/File APIs...
I might just do that - it might be fun. ;-)

tomcats default directory is where ever you called the startup.sh/bat file.
So if you dont use another script to call the startup.sh/bat file tomcats
default will be the bin directory.
Use this code to find the directory where WEB-INF is. Then you can traverse
your directory structure from there.

Re: Quick Question
Alex, Probably the current working directory, which is whatever directory Tomcat was started out of (probably bin/, but not necessarily so). You can provide a full file name in the code, or use your web.xml to set a context parameter that indicates a base path to do read/write relative to in your servlet. You could also put that file somewhere your web application's Classloader will see it and load it via a findResource() or getResourceAsStream().

RE: Quick Question
Hi all,
I'm trying to resolve this problem with all the solutions that you gave
me, but it doesn't work...
This is what I did:
in my java bean (not a servlet), I have this code:
public class DbBean {
public int Connect() {
InputStream is =
Thread.currentThread().getContextClassLoader().getResourceAsStream(config.txt);
if (is == null) {
return 0;
}
else {
return 1;
}
}
then in my jsp, I called this method, and then I write the value (0 or
1)..
The txt file is in WEB-INF/classes/beans..., because DbBean is in a
package called beans, and I start tomcat from TOMCAT_HOME/bin..
When I load the jsp, the method Connect of the DbBean (java bean) returned
0, which means the InputStream is null, but if I put the txt file in
TOMCAT_HOME/bin, I had no problem, the method returned 1 why is
that??.. I'm using Tomcat 3.2
Do I need to set something else in Tomcat??
thanks again

hi what you should try to do is either from your jsp use the method I suggested before and pass the info to your bean, or if this is a config file, use this method which works I have just tried it, to load your file into a properties class.

RE: Quick Question
If you are only reading the file, you could also put it in your $/WEB-INF/classes folder and use the class loader to get an input stream. That way, if you jar/war the file up, it will still find it. Like this: InputStream is = Thread. currentThread(). getContextClassLoader(). getResourceAsStream(config.txt); Also, a change to config.txt will trigger a reload, so in development, you do not need to restart or otherwise force the file to get reloaded. Not sure if this makes sense in your case, but it is another option.
