I have read the Tomcat 6.0 classloader documentation(below link),
from this what i understood is that the
"classes/jar/resource/properties file" get loaded from the following
locations
1.Bootstrap classes of your JVM ($JAVA_HOME/jre/lib/ext). 2.System
class loader classes ( Add bootstrap.jar & tomcat-juli.jar to
CLASSPATH variable) 3.Common class loader classes ( refers
$CATALINA_BASE/lib & $CATALINA_HOME/lib ) & uses
$CATALINA_BASE/conf/catalina.properties 4. /WEB-INF/classes of your
web application 5. /WEB-INF/lib/*.jar of your web application
The thing which is still puzzling me is that how my
"resource/properties files" get loaded to Tomcat CLASSPATH when i add
them to "$CATALINA_BASE/bin" directory & When i move the same files
to $CATALINA_BASE/conf directory then it doesn't get added to Tomcat
CLASSPATH.
My deployed applications need"properties/resource files ", Can
someone please help me in understand the optimal way of adding these
files to Tomcat CLASSPATH. Does placing the files under
<CATALINA_BASE>/bin is the right approach.Please suggest
Why in the world are you adding these resource files to Tomcat's
CLASSPATH? If the resources are application - specific, you don't need
to do this at all.
Just add the files to your local application. In Maven, there's a
special directory for that:
src/main/resources
In NetBeans, I normally create a separate package for all of my
configuration files.
I think in Eclipse you'll have to make a subdirectory under
WEB-INF/classes and copy the files there. That's unpleasant. Eclipse
will include that in the build of the WAR file when you do an "export".
Then, just do the following in your code to reference the resource.
InputStream in =
this.getClass().getClassLoader().getResourceAsStream(configfile);
Where configfile is the complete classpath to your resource.
This is nice. It works in exploded WARs, it works in WAR files, it works
in JARs.
No mucking about with CLASSPATH. No polluting other applications or
Tomcat with spurious application - specific resources. This enables you
to run several copies of the same web application in the same container,
all with different configurations.
Just search for getResourceAsStream() for more explanation.
In my organisation i cannot add anything to "$CATALINA_HOME/lib or
bin" location ,these are read only directories

Application is deployed under tomcat webapps directory . It tries
to refer to application specific properties file from tomcat
classpath, for that we copied it under tomcat bin directory.
My query is that does this is the right way to add properties file
to tomcat classpath?
Did you try putting it in tomcat/lib?

I have a requirement in which i need to add couple of
properties files to tomcat CLASSPATH as these are needed for my
application deployed in Tomcat 6.0.
One strange thing is that, i need to add the all my properties
files to "<CATALINA_BASE>/bin" directory else these all wont
get added to Tomcat classpath.
Where does the code live that attempts to load those properties
files?
