My problem is that the class cannot location my properties file. I am

The problem is that you appear to be loading a file with an absolute path,
versus the common form of load a properties file via the ClassLoader.
Fumble about with the ClassLoader.getResourceAsStream to have it hunt down
your properties file, and then feed that stream to your Properties.
public static yourMethod()
{
ClassLoader cl = YourClass.class.getClassLoader();
Properties prop = new Properties();
prop.load(cl.getResourceAsStream(yours.properties));
}
Then, just drop your properties at the right place in your WARs classes
area.

Re: Loading Properties Files
Thats right.
If you don't have a .war file, you can use the classes dir inside your WEB-INF
dir, and create a new directory like conf, the put inside all the properties
files. In that way the ClassLoader looks for the files in there when you use
something like this:
try {
Properties props = new Properties();
InputStream in = getClass().getResourceAsStream(/conf/db.properties);
props.load(in);
..
propertie1 = props.getProperty(propertie1);

RE: Loading Properties Files
Depends upon what you want to do with the properties files and how you
access them. Some ways of accessing them require that the name to access
be relative to the classpath, others don't. You are better off to learn
about properties files in this instance. There is nothing peculiar to the
web-structure that I know of that is important about locating properties
files.

Re: Loading Properties Files
If you're using the ClassLoader to locate your properties files, then the
properties files need to be within your classpath. For WARs, the only places
that you really have much control over is the 'classes' directory.
The other issue is that your can not assume that you will be able to write
to you properties files.

RE: Loading Properties Files
No, that's not true at all.
The examples already given will find properties files for you just fine
whether the file is in a directory structure or inside an archive. How do
you think Java loads classes? It works out of archives, no?
here are some various was to access a properties file ( or any resource,
for that matter) in whether the app is deployed as a directory or as a .war
file (even inside a .jar file in WEB-INF/lib)
This will load a file in WEB-INF/classes/conf or any jar file in the
classpath with a package of conf...
getClass().getResourceAsStream(/conf/db.properties);
This will load a file relative to the current class. For instance, if the
class is org.mypackage.MyClass, then the file would be loaded at
org.mypackage.conf.dbproperties. Note that this is because we didn't
prepend / to the path. When that is done, the file is loaded from the
root of the current classloader where this loads it relative to the current
class...
getClass().getResourceAsStream(conf/db.properties);
this will find db.properties anywhere in the current classloader as long as
it exists in a conf package...
getClass().getClassLoader().getResourceAsStream(conf/db.properties);
This will find the file in a conf directory inside the webapp (starting
from the root). This starts looking in the same directory as contains
WEB-INF. When I say directory, I don't mean filesystem. This could be
in a .war file as well as in an actual directory on the filesystem...
getServletContext().getResourceAsStream(/conf/db.properties);
of course you would probably not want just anyone seeing your db.properties
file, so you'd probably want to put in inside WEB-INF of your webapp, so
getServletContext().getResourceAsStream(/WEB-INF/conf/db.properties);
If your db.properties exists in another classloader which your app has
access to, you can reach it by using:
Thread.currentThread().getContextClassLoader().getResourceAsStream(conf/db.properties);
That will act similar to getClass().getClassLoader(), but it can see across
all available classloaders where the latter can only see within the
classloader that loaded the current class.
So, as you can see, you have quite a number of options. There you go.

A WAR file has the same format as a JAR file, but a servlet container --
and most especially the class loader for a webapp that the a servlet
container provides -- very definitely *does* know where to look in a WAR
for unpacked classes/resources (in /WEB-INF/classes) or JAR files
containing classes/resources (in /WEB-INF/lib). That's why Tomcat is
perfectly capable of running a webapp directly from a WAR, without
unpacking it.
As long as you use the correct resource paths (as shown in the examples),
you can access properties files under /WEB-INF/classes (or from JAR files
in /WEB-INF/classes). These calls are required to work whether the WAR is
unpacked or not.

This will load a file in WEB-INF/classes/conf or any jar file in the
classpath with a package of conf...
getClass().getResourceAsStream(/conf/db.properties);
This will load a file relative to the current class. For instance, if the
class is org.mypackage.MyClass, then the file would be loaded at
org.mypackage.conf.dbproperties. Note that this is because we didn't
prepend / to the path. When that is done, the file is loaded from the
root of the current classloader where this loads it relative to the
current class...
getClass().getResourceAsStream(conf/db.properties);
this will find db.properties anywhere in the current classloader as long
as it exists in a conf package...
getClass().getClassLoader().getResourceAsStream(conf/db.properties);
This will find the file in a conf directory inside the webapp (starting
from the root). This starts looking in the same directory as contains
WEB-INF. When I say directory, I don't mean filesystem. This could
be in a .war file as well as in an actual directory on the filesystem...
getServletContext().getResourceAsStream(/conf/db.properties);
of course you would probably not want just anyone seeing your
db.properties file, so you'd probably want to put in inside WEB-INF of
your webapp, so
getServletContext().getResourceAsStream(/WEB-INF/conf/db.properties);
If your db.properties exists in another classloader which your app has
access to, you can reach it by using:
Thread.currentThread().getContextClassLoader().getResourceAsStream(conf/db.properties);
That will act similar to getClass().getClassLoader(), but it can see
across all available classloaders where the latter can only see within the
classloader that loaded the current class.
So, as you can see, you have quite a number of options. There you go.

Depends upon what you want to do with the properties files
and how you
access them. Some ways of accessing them require that the
name to access
be relative to the classpath, others don't. You are better
off to learn
about properties files in this instance. There is nothing
peculiar to the
web-structure that I know of that is important about locating
properties
files.

Thats right.
If you don't have a .war file, you can use the classes dir
inside your WEB-INF
dir, and create a new directory like conf, the put inside
all the properties
files. In that way the ClassLoader looks for the files in
there when you use
something like this:
try {
Properties props = new Properties();
InputStream in =
getClass().getResourceAsStream(/conf/db.properties
Re: Loading properties files
Your properties file must be in a location that Tomcat knows about via its
classpath (WEB-INF/classes is on Tomcat's classpath, that's why it worked
when your file was there). See the Tomcat docs under Classpath How-to,
which describes the class loaders in Tomcat.

Hi,
Could u tell me what is not correct with that :
Before we had that ( the properties files were in WEB-INF/classes ) and
that works :
package com.a2a.util ;
public interface A2aConstantes
{
public static final String SCHEMA =
java.util.ResourceBundle.getBundle(db).getString(schema);
}
Now we want to have properties files in WEB-INF/config so we change
the file like this :
package com.a2a.util ;
public interface A2aConstantes
{
public static final String SCHEMA =
java.util.ResourceBundle.getBundle(/WEB-INF/config/db).getString(sche
ma);
}
But it doesnot work, it can't find the db.properties. I have tried with
WEB-INF/config/db and /WEB-INF/config/db.properties but
it doesnot work too.
Can u tell me what's wrong ?

why is it tomcat could not locate the property file if i place it on the

directory isnt it? just need some more clarifications.
e.g WEB-INF/classess/com/test/MyProperty.properties

Re: Loading properties files
java.util.ResourceBundle.getBundle() uses the current ClassLoader to load
your resource bundle. That means that your properties have to either be
located with a jar file in /WEB-INF/lib or in your /WEB-INF/classess directory.
This isn't a limitation of Tomcat, this is how resource bundles work.

Re: Loading properties files
we're using something like (off the top of my head):
System.getResourceAsStream(com/domain/package/file.properties)
and that works; until we fixed our app deployment structure, we had to use
getSystemResourceAsStream (we were putting things in common/lib when we
shouldn't have).

Why do you insist on putting your property file in /WEB-INF/config?
Just create a jar with your property file and put it in /WEB-INF/lib,
or put the property file in /WEB-INF/classes.
